Exploring the feasibility of validating early developmental screening tools for American Indian and Alaska Native children.

Screening children from birth through age 5 is critical to early identification of challenges and referral to intervention to support optimal development. Screening of American Indian and Alaska Native (AIAN) children lags behind that of other children, partly due to the lack of screening tools validated for this population. This study tested the feasibility of an online data collection strategy for use in a future study of the validity of existing screening instruments for AIAN children. Parents of AIAN children in four communities were recruited to complete screeners, provide demographic information, and provide feedback on experiences with online data collection. Participants were given the option of receiving screening results from the local early childhood program through which they were recruited. 240 participants began the process, 183 were enrolled in a partner program and reported a birthdate for at least one AIAN child, 157 had an age-eligible child, 81 began the consent process, 62 consented, and 39 fully completed data collection. Most participants were female and AIAN, the majority reported that online data collection was easy. Collecting screener validation data on a large sample of AIAN children may be able to utilize online data collection tools, with in-person support to facilitate participation.

Un examen de detección en los niños a partir del nacimiento hasta la edad de 5 años es esencial para la temprana identificación de retos y la referencia a intervenciones como apoyo a un desarrollo óptimo. El examen de detección en el caso de niños del grupo Indio Americano y Nativo de Alaska (AIAN) está muy por debajo del de otros niños, en parte debido a la falta de herramientas de detección validadas para esta población. Este estudio puso a prueba la posibilidad de una estrategia electrónica de recolección de datos para uso en un estudio futuro acerca de la validez de los existentes instrumentos de detección para niños AIAN. Se reclutaron progenitores de niños AIAN en cuatro comunidades para completar los exámenes de detección, proveer información demográfica, así como proveer información sobre las experiencias con la recolección electrónica de datos. A los participantes se les dio la opción de recibir los resultados de la detección de parte del programa local para la temprana niñez a través del cual habían sido reclutados. 240 participantes comenzaron el proceso; 183 estaban matriculados en un programa paralelo y reportaron la fecha de nacimiento de por lo menos un niño AIAN; 157 tenían un niño elegible según la edad; 81 comenzaron el proceso de consentimiento; 62 consintieron; 39 completaron en su totalidad la recolección de datos. La mayoría de los participantes eran mujeres y AIAN; la mayoría reportó que la recolección electrónica de datos fue fácil. La recolección de información de validación de la detección en un grupo muestra grande de niños AIAN pudiera ser capaz de utilizar herramientas electrónicas de recolección de datos, con un apoyo presencial para facilitar la participación.

Le dépistage des enfants de la naissance à l'âge de 5 ans est critique pour l'identification précoce des défis et problèmes et l'orientation vers l'intervention afin de soutenir le développement optimal. Le dépistage des enfants d'amérindiens des Etats-Unis et des autochtones d'Alaska est en retard par rapport à celui des autres enfants, en partie du fait du manque d'outils de dépistage validés pour cette population. Cette étude a testé la fiabilité de la stratégie de collecte de données en ligne pour son utilisation pour une étude à venir sur la validité d'instruments de dépistage existants pour les enfants AIAN. Les parents d'enfants AIAN de quatre communautés ont été recrutés afin de remplir des dépistages, d'offrir des renseignements démographiques, et d'offrir des commentaires sur les expériences de collecte de données en ligne. Les participants ont reçu l'option de recevoir les résultats de dépistage d'un programme de petite enfance local au travers duquel ils avaient été recrutés. 240 participants ont commencé le processus. 183 ont été inscrits dans un programme partenaire et ont fait état de la date de naissance d'au moins un enfant AIAN. 157 avait un enfant admissible par l'âge. 81 ont commencé le processus de consentement. 62 ont consenti. 39 ont fini la collecte de données en ligne. La collecte de données de validation du filtre de recherche sur un grand échantillon d'enfants AIAN pourrait utiliser des outils de collecte de données en ligne avec un soutien en personne afin de faciliter la participation.

Evaluation of the use of psychometric scales in human-wildlife interaction research to determine attitudes and tolerance toward wildlife.

Studies evaluating human-wildlife interactions (HWIs) in a conservation context often include psychometric scales to measure attitudes and tolerance toward wildlife. However, data quality is at risk when such scales are used without appropriate validation or reliability testing, potentially leading to erroneous interpretation or application of findings. We used 2 online databases (ProQuest Psych Info and Web of Science) to identify published HWI studies that included attitude and tolerance. We analyzed these studies to determine the methods used to measure attitudes or tolerance toward predators and other wildlife; determine the proportion of these methods applying psychometric scales; and evaluate the rigor with which the scales were used by examining whether the psychometric properties of validity and reliability were reported. From 2007 to 2017, 114 published studies were identified. Ninety-four (82%) used questionnaires and many of these (53 [56%]) utilized a psychometric scale. Most scales (39 [74%]) had at least 1 test of reliability reported, but reliance on a single test was notable, contrary to recommended practice. Fewer studies (35 [66%]) reported a test of validity, but this was primarily restricted to structural validity rather than more comprehensive testing. Encouragingly, HWI investigators increasingly utilized the necessary psychometric tools for designing and analyzing questionnaire data, but failure to assess the validity or reliability of psychometric scales used in over one-third of published HWI attitude research warrants attention. We advocate incorporation of more robust application of psychometric scales to advance understanding of stakeholder attitudes as they relate to HWI.

Análisis del Uso de Escalas Psicométricas en la Investigación sobre la Interacción Humano-Fauna para Determinar Actitudes y Tolerancia hacia la Fauna Resumen Los estudios que analizan las interacciones humano-fauna (IHF) dentro de un contexto de conservación con frecuencia incluyen escalas psicométricas para medir las actitudes y la tolerancia hacia la fauna. Sin embargo, la calidad de los datos se encuentra en riesgo cuando dichas escalas se usan sin una validación apropiada o una prueba de confiabilidad, lo que potencialmente puede llevar a interpretaciones o aplicaciones erróneas de los resultados. Usamos dos bases de datos virtuales (ProQuest Psych Info y Web of Science) para identificar estudios publicados sobre las IHF que incluyeran actitud y tolerancia. Analizamos estos estudios para determinar los métodos utilizados para medir las actitudes o la tolerancia hacia los depredadores y otros tipos de fauna; determinar la proporción de estos métodos aplicando escalas psicométricas; y evaluar el rigor con el cual se usaron las escalas al examinar si las propiedades psicométricas de validez y confiabilidad estuvieron reportadas en el estudio. Identificamos 114 estudios publicados entre 2007 y 2017. De estos estudios, 94 (82%) usaron cuestionarios y muchos de estos cuestionarios (53 [56%]) usaron una escala psicométrica. La mayoría de las escalas (39 [74%]) tuvieron al menos una prueba de confiabilidad reportada, pero la dependencia de una sola prueba fue notable, contrario a la práctica recomendada. Fueron menos los estudios (35 [66%]) que reportaron una prueba de validez, pero esto estuvo restringido primordialmente a una validez estructurada en lugar de un análisis más integral. De manera alentadora, los investigadores de las IHF cada vez usaron más las herramientas psicométricas necesarias para diseñar y analizar los datos de los cuestionarios, aunque la falta de análisis de la validez o confiabilidad de las escalas psicométricas utilizadas en más de un tercio de los estudios publicados sobre las actitudes hacia las IHF requiere de atención. Promovemos la incorporación de una aplicación más sólida de las escalas psicométricas para propiciar el entendimiento de las actitudes de los actores sociales conforme se relacionan con las IHF.

Reliability of evidence-review methods in restoration ecology.

In restoration science, evidence reviews play a crucial role in summarizing research findings in practice and policy. However, if unreliable or inappropriate methods are used to review evidence, decisions based on these reviews may not accurately reflect the available evidence base. To assess the current value of restoration reviews, we examined a sample of meta-analyses and narrative syntheses (n = 91) with the Collaboration for Environmental Evidence Synthesis Assessment Tool (CEESAT), which uses detailed criteria to assesses the method of policy-relevant evidence synthesis according to elements important for objectivity, transparency, and comprehensiveness. Overall, reviews scored low based on this standard: median score 16 out of 39, modal score 15, and mean 16.6. Meta-analyses scored higher than narrative syntheses (median 17 vs. 5, respectively), although there were some outlier narrative syntheses that had high scores, suggesting that quantitative synthesis does not solely reflect the reliability of a review. In general, criteria spanning the more fundamental review stages (i.e., searching for studies and including studies) received low scores for both synthesis types. Conversely, criteria comprising the later stages of the review (i.e., critical appraisal, data extraction, and data synthesis) were generally well described in meta-analyses; thus, these criteria achieved the highest individual CEESAT scores. We argue that restoration ecology is well positioned to advance so-called evidence-based restoration, but review authors should elucidate their conceptual understanding of evidence syntheses and recognize that conducting reliable reviews demands the same methodological rigor and reporting standards used in primary research. Given the potential of evidence reviews to inform management, policy, and research, it is of vital importance that the overall methodological reliability of restoration reviews be improved.

Confiabilidad de los Métodos de Revisión de Evidencias en la Ecología de Restauración Resumen Para las ciencias de la restauración, las revisiones de evidencias juegan un papel muy importante en la síntesis de los hallazgos de las investigaciones en la práctica y en las políticas. Sin embargo, si se usan métodos poco fiables o inapropiados para revisar las evidencias, las decisiones que se tomen con base en estas revisiones pueden no reflejar acertadamente la base disponible de evidencias. Para analizar el valor actual de las revisiones de restauraciones examinamos una muestra de metaanálisis y síntesis narrativas (n = 91) con la Herramienta para la Síntesis de Análisis de la Colaboración para la Evidencia Ambiental (CEESAT), la cual usa criterios detallados para analizar el método de síntesis de evidencias relevantes para las políticas de acuerdo con los elementos importantes para la objetividad, transparencia y exhaustividad. En general, las revisiones tuvieron puntajes bajos con base en este estándar (puntaje medio: 16 de 39, puntaje modal: 15, media: 16.6). Los metaanálisis tuvieron un puntaje más alto que las síntesis narrativas (mediana: 17 vs 5, respectivamente), aunque hubo algunas síntesis narrativas atípicas que tuvieron puntajes altos, lo que sugiere que la síntesis cuantitativa no refleja por sí sola la confiabilidad de una revisión. En suma, los criterios que abarcaron las etapas de revisión más fundamentales (es decir, buscar estudios e incluir estudios) recibieron puntajes bajos para ambos tipos de síntesis. Al contrario, los criterios que comprendieron las etapas tardías de la revisión (es decir, la valoración crítica, la extracción de datos y la síntesis de los datos) estuvieron generalmente bien descritos en los metaanálisis; por lo tanto, estos criterios alcanzaron los puntajes CEESAT individuales más altos. Argumentamos que la ecología de restauración se encuentra bien posicionada para adelantar la llamada restauración basada en evidencias, pero los autores de las revisiones deberían aclarar su entendimiento conceptual de la síntesis de evidencias y reconocer que la realización de revisiones confiables requiere el mismo rigor metodológico y los mismos estándares de reporte usados en la investigación primaria. Dado el potencial que tienen las revisiones de evidencias para orientar el manejo, las políticas y la investigación, es de vital importancia que se mejore la confiabilidad metodológica generalizada de las revisiones de restauración.

Validity and reliability of the Inflammatory Bowel Disease Fatigue Scale in Mexican patients.

INTRODUCTION: Fatigue is an extra-intestinal manifestation of inflammatory bowel disease (IBD). OBJECTIVE: To determine the construct validity, discriminant validity and reliability of an instrument for evaluating the Fatigue Scale for IBD in Mexican patients. METHODS: Two hundred patients with an IBD confirmed diagnosis were included. Current demographic and clinical characteristics of the condition were evaluated. Each patient answered the IBD Fatigue Scale (IBD-F) and the Pittsburgh Sleep Quality Index (PSQI), which was used to determine IBD-F discriminant validity. A factor analysis of each IBD-F section was performed, independent sample Student's t-tests were used to contrast the PSQI, and reliability was evaluated using Cronbach's alpha. RESULTS: The items in both IBD-F sections showed high factor loadings, which explained 68.3 and 38.4% of variance, respectively. Cronbach's alpha was > 0.80 in both, which discriminated patients with greater sleep disturbances. CONCLUSIONS: IBD-F is a valid and reliable scale for Mexican patients with IBD. Fatigue objective evaluation will allow timely interventions in order to reduce its impact on patients with IBD.

INTRODUCCIÓN: La fatiga es una manifestación extraintestinal de la enfermedad inflamatoria intestinal (EII). OBJETIVO: Obtener la validez de constructo, la validez discriminante y la confiabilidad de un instrumento para evaluar una escala de fatiga para EII en pacientes mexicanos. MÉTODOS: Se incluyeron 200 pacientes con diagnóstico confirmado de EII. Se evaluaron las características demográficas y clínicas actuales del padecimiento. Cada paciente contestó la Escala de Fatiga para EII (IBD-F) y el Índice de Calidad de Sueño de Pittsburgh (PSQI), empleado para determinar la validez discriminante de la IBD-F. Se realizó un análisis factorial de cada sección de la IBD-F, se utilizó la t de Student de muestras independientes para el contraste del PSQI y la confiabilidad se evaluó mediante alfa de ZCronbach. RESULTADOS: Los reactivos de ambas secciones de la IBD-F mostraron altas cargas factoriales, que explicaron 68.3 y 38.4 % de la varianza, respectivamente. El alfa de Cronbach fue > 0.80 en ambas, las cuales discriminaron a los pacientes con mayores alteraciones en el sueño. CONCLUSIONES: La IBD-F es una escala válida y confiable para pacientes mexicanos con EII. La evaluación objetiva de la fatiga permitirá realizar intervenciones oportunas para disminuir el impacto de esta manifestación en el paciente con EII.

Tools for assessing the psychometric adequacy of latent variables in conservation research.

Conservation psychology has a history of measuring variables that cannot be seen (e.g., values, attitudes, norms). Such latent variables are critical drivers of human action and are often measured using responses to survey questions. Tools for establishing the psychometric adequacy of unobservable, latent variables has been a century-long pursuit and challenge for quantitative psychologists and statisticians. Fundamental questions at the heart of this challenge include is what is claimed to be measured (validity) being measured and is measurement consistent (reliability)? We examined common methods used to establish the validity and reliability of psychometric instruments. Through a case study of anglers in Texas, we investigated the protocols and metrics used to evaluate the measurement of latent variables. The indicators we tested (identity, awareness of consequences, ascription of responsibility, and personal norms) validly and reliably assessed latent variables. Our findings also illustrated decision protocols (e.g., discriminant validity, convergent validity, internal consistency) involved in assessing the psychometric adequacy of latent variable indicators. The ability to correctly identify significant relationships among unobserved variables and their influence on human action is directly tied to the adequacy of measurement. In an era of instability and change that threatens social-ecological systems worldwide, the need for accuracy and precision in conservation social science has never been greater. Research that employs flawed measures has potential to lead to erroneous conclusions and undermine conservation and biodiversity protection.

Herramientas para Evaluar la Idoneidad Psicométrica de las Variables Latentes en la Investigación de la Conservación Resumen La psicología de la conservación tiene la reputación de medir variables que no pueden ser vistas (p. ej.: valores, actitudes, normas). Dichas variables latentes son impulsores importantes de la acción humana y con frecuencia se miden usando las respuestas dadas en una encuesta. Las herramientas para establecer la idoneidad psicométrica de las variables inobservables y latentes ha sido una búsqueda y un desafío de todo un siglo para los psicólogos cuantitativos y los estadistas. Las cuestiones fundamentales en el núcleo de este desafío son: si es medido lo que se dice está siendo medido (validez) y si la medición es uniforme (confiabilidad). Examinamos los métodos comunes usados para establecer la validez y la confiabilidad de los instrumentos psicométricos. Mediante un estudio de caso de pescadores en Texas, investigamos los protocolos y las medidas usadas para evaluar la medida de las variables latentes. Los indicadores que analizamos (identidad, noción de las consecuencias, adscripción de la responsabilidad y normas personales) evaluaron a las latentes variables en validez y confianza. Nuestros hallazgos también reflejaron los protocolos de decisión (p. ej.: x, y, z) involucrados en la evaluación de la idoneidad psicométrica de los indicadores de variables latentes. La habilidad para identificar correctamente las relaciones significativas entre las variables no observadas y su influencia sobre las acciones humanas está vinculada directamente a la idoneidad de la medición. Hoy en día, en esta época de inestabilidad y cambio que amenaza a los sistemas socio-ecológicos en todo el mundo, la necesidad de tener certeza y precisión en las ciencias sociales de la conservación nunca ha sido tan grande. Las investigaciones que emplean medidas imperfectas tienen el potencial de derivar en conclusiones erróneas y perjudicar a la conservación y a la protección de la biodiversidad.

The My Emotions Questionnaire: A self-report of mothers' emotional responses to infant crying.

The purpose of this article was to examine the psychometrics of the My Emotions Questionnaire, a self-report designed to assess mothers' emotional reactions when their infants cry. Participants were 240 first-time mothers. When infants were 6 months and 1 year old, mothers completed the new questionnaire and measures assessing beliefs and behavioral responses to infant crying, and interview-based measures of mothers' emotional reactions and causal attributions about crying were administered. Maternal sensitivity and negative behaviors were observed when infants were 6 months and 1 and 2 years old. Mothers reported on their discipline practices when children were 2 years old. Five emotion factors emerged based on exploratory factor analysis (EFA) of the 6-month data: Amusement, Anxiety, Frustration, Sympathy, and Protective. The five-factor structure was supported via a confirmatory factor analysis (CFA) of the 1-year data. All scales demonstrated adequate internal consistency reliability and significant stability from 6 months to 1 year. Amusement, Frustration, and Protectiveness demonstrated the best convergent validity with cry cognitions and predictive validity to parenting measures, followed by Anxiety, although effects tended to be small to moderate. Evidence for the validity of Sympathy was less compelling. The potential utility of the questionnaire for basic and applied research is discussed.

El propósito de este ensayo fue examinar la sicometría del Cuestionario Mis Emociones, un auto-reporte diseñado para evaluar las reacciones emocionales de las madres cuando sus infantes lloran. Las participantes fueron 240 madres primerizas. Cuando los infantes tenían 6 meses y 1 año de edad, las madres completaron el nuevo cuestionario y se les administraron medidas para evaluar creencias y la conducta de respuesta al llanto del infante, así como medidas basadas en entrevistas sobre las reacciones emocionales de las madres y atribuciones causales acerca del llanto. Cuando los infantes tenían 6 meses, 1 año y 2 años, se observaron la sensibilidad materna y las conductas negativas. Las madres reportaron acerca de sus prácticas disciplinarias cuando los niños tenían 2 años. Cinco factores de emoción surgieron de la información a los 6 meses, con base en los análisis exploratorios de factores: diversión, ansiedad, frustración, simpatía y actitud de protección. La estructura de cinco factores fue apoyada por medio de un análisis confirmatorio de factores de la información de 1 año. Todas las escalas demostraron una confiabilidad adecuada de consistencia interna y significativa estabilidad desde los 6 meses hasta 1 año. La diversión, la frustración y la actitud de protección demostraron la mejor validez convergente con conocimientos del llanto y validez predictiva hacia las medidas de crianza, y fueron seguidas por la ansiedad, aunque los efectos tendieron a ser entre pequeños y moderados. La evidencia por la validez de la simpatía fue menos convincente. Se discute la posible utilidad del cuestionario para la investigación básica y aplicada.

Le but de cet article était d'examiner la psychométrie du Questionnaire Mes Emotions, une auto-évaluation conçue pour évaluer les réactions émotionnelles des mères lorsque leurs bébés pleurent. Les participantes étaient 240 mères pour la première fois. Lorsque les bébés avaient 6 mois et 1 an, les mères ont rempli le nouveau questionnaire et les mesures évaluant les croyances et les réactions comportementales aux pleurs du bébé et des mesures basées sur des entretiens de réactions émotionnelles des mères et les attributions causales sur les pleurs ont été administrées. La sensibilité maternelle et les comportements négatifs ont été observés lorsque les enfants avaient 6 mois, 1 an, 2 ans. Les mères ont fait état de leurs disciplinaires quand les enfants avaient 2 ans. Cinq facteurs d'émotion ont émergé, basé sur l'analyse des facteurs exploratoires des données de 6 mois : amusement, anxiété, frustration, sympathie et protectrice. La structure de 5 facteurs a été soutenue au travers d'une analyse des facteurs de confirmation des données d'une année. Toutes les échelles ont démontré une fiabilité adéquate de la cohérence interne et une stabilité importante de 6 mois à 1 an. L'amusement, la frustration et la protection ont démontré la meilleure validité convergente avec les cognitions des pleurs et la validité prédictive aux mesures de parentages suivies par de l'anxiété, bien que les effets avaient tendance à être petits à modérés. Les preuves de la validité de la sympathie étaient moins convaincantes. L'utilité potentiel du questionnaire pour les recherches de base et les recherches appliquées sont discutées.

Reliability and validity of the EASYCare-2010 Standard to assess elderly people in Portuguese Primary Health Care.

INTRODUCTION: The EASYCare is a multidimensional assessment tool for older people, which corresponds to the concerns and priorities of older people in relation to their needs, health, and quality of life. The EASYCare instrument has been used in many countries worldwide. Lack of reliability evidence has recently been raised by researchers. This study aimed to test the validity and reliability of the EASYCare-2010 instrument in community-dwelling Portuguese older people attended in Primary Health Care centres. METHODS: The sample for this transversal study (N=244) was collected from Portuguese Primary Health Care Centers. Categorical Principal Component Analysis was used to assess the underlying dimensions of EASYCare-2010. Construct validity was evaluated through correlation with the World Health Organization Quality of Life Assessment Instrument-Short Form. RESULTS: A two-factor model (labelled "mobility and activities of daily life", and "general well-being and safety") was found. The EASYCare-2010 instrument showed acceptable levels for internal consistency (≥0.70). The EASYCare-2010 factors were correlated with measures of quality of life. Results showed that in most polytomous items, some of the more extreme categories were not considered at all or only by a residual number of participants. CONCLUSION: EASY Care -2010 version is a valid and reliable instrument for holistic assessment of the older people attended in Primary Health Care centres in Portugal.

Psychometric properties of the Spanish version of the Pediatric Quality of Life Inventory Family Impact Module (PedsQL FIM).

INTRODUCTION: This study analysed the psychometric properties of the Spanish version of the Pediatric Quality of Life Questionnaire Family Impact Module (PedsQL FIM) in the Argentinian population. PATIENTS AND METHODS: The sample included 232 caregivers, of who 108 were parents of children with chronic diseases (mean, 9.54; standard deviation [SD], 4.43) and 124 parents of children in the general population (mean, 12.37; SD, 4.6). RESULTS: We assessed the validity of the instrument with the known-groups method, finding significant differences between the case and control groups in the overall and subscale scores (P < .01). We also assessed test validity by means of exploratory factor analysis, which yielded an 8-factor model that explained 74.03% of the variance. We assessed reliability with the Cronbach alpha and found a high internal consistency (α=0.95). CONCLUSION: The PedsQL module proved to be a valid and reliable tool to assess the impact of a chronic paediatric condition on caregiver quality of life and family functioning.

Scale of concern about COVID-19 infection in Peruvian Health Care Workers.

INTRODUCTION: The global SARS-CoV-2 pandemic has generated concern about contagion, especially among healthcare workers who are on the front line. OBJECTIVE: To design and analyse the evidence of content validity, internal structure and reliability of a measure of concern about the spread of COVID-19 among Peruvian healthcare workers. MATERIAL AND METHODS: Quantitative study and instrumental design. The scale was administered to 321 health science professionals (78 males and 243 females), whose ages ranged from 22 to 64 years (38.12 ±â€¯9.61). RESULTS: Aiken's V-coefficient values were statistically significant. An exploratory factor analysis was performed which indicated the existence of a single factor, and confirmatory factor analysis (CFA) confirmed a satisfactory six-factor model. The CFA solution obtained adequate fit indices (RMSEA = 0.079; P = .05; TLI = 0.967; IFC = 0.980; GFI = 0.971, and AGFI = 0.931), and showed good internal consistency based on Cronbach's alpha coefficient (α = 0.865; CI 95%, 0.83-0.89). CONCLUSIONS: The scale of concern for COVID-19 infection is a valid and reliable brief measure that can be used for research and professional purposes.

Are YouTube videos on smell dysfunction a good source of information for patients seeking a cure for their illness?

OBJECTIVE: To conduct unbiased research into the quality and reliability of videos published on YouTube on the subject of smell dysfunction and treatment through two Ear, Nose, and Throat (ENT) specialists using three different tools. METHODS: The videos were separated into two groups (reliable: Group 1; non-reliable: Group 2) according to whether or not the content was scientifically reliable, proven, accurate, and useful, as determined by two ENT specialist physicians. The DISCERN reliability tool, Global quality scale (GQS), and JAMA scoring system were used as video scoring tools in the evaluations. RESULTS: Group 1 included 173 videos, and Group 2, 16 videos. The GQS (First ENT specialist) points were 3 (2-5) and GQS (Second ENT specialist) points were 3 (2-5) in Group 1, and 2 (2-3) and 2 (1-3) in Group 2, respectively (p = 0.0001). The points in the DISCERN and JAMA scoring systems were found to be higher in Group 1 than in Group 2 (p = 0.0001). CONCLUSION: Although the majority of videos on YouTube related to smell dysfunction are reliable, the number of unreliable videos is not inconsiderable. When videos related to medical information are accepted onto YouTube, weighting should be given to videos which include scientifically proven evidence uploaded by specialist professionals and institutions.

OBJETIVO: realizar una investigación imparcial sobre la calidad y la confiabilidad de los videos publicados en YouTube sobre el tema de la disfunción y el tratamiento del olfato, a través de dos especialistas en oído, nariz y garganta que utilizan tres herramientas diferentes. MÉTODOS: Los videos se separaron en dos grupos (confiables: Grupo 1; no confiables: Grupo 2) según si el contenido era o no científicamente confiable, probado, preciso y útil, según lo determinado por dos médicos especialistas en Otorrinolaringología. La herramienta de confiabilidad DISCERN, la escala de calidad global (GQS) y el sistema de puntuación JAMA se utilizaron como herramientas de puntuación de video en las evaluaciones. RESULTADOS: el Grupo 1 incluyó 173 videos y el Grupo 2, 16 videos. Los puntos GQS (Primer especialista en ORL) fueron 3 (2-5) y los puntos GQS (Segundo especialista en ORL) fueron 3 (2-5) en el Grupo 1, y 2 (2-3) y 2 (1-3) en el Grupo 2, respectivamente (p= 0.0001). Se encontró que los puntos en los sistemas de puntuación DISCERN y JAMA eran más altos en el Grupo 1 que en el Grupo 2 (p= 0.0001). CONCLUSIÓN: aunque la mayoría de los videos en YouTube relacionados con la disfunción del olfato son confiables, la cantidad de videos poco confiables no es despreciable. Cuando se aceptan videos relacionados con información médica en YouTube, se debe dar peso a los videos que incluyen evidencia científicamente probada y subidos por instituciones y profesionales especialistas.

Validity and reliability of the Turkish version of the Parent Attitudes About Childhood Vaccines (PACV) scale.

AIMS: This study aimed to determine the validity and reliability of the Turkish version of the "Parental Attitudes toward Childhood Vaccines" (PACV) scale. MATERIALS AND METHODS: A two-stage observational validation study was conducted. A back-translation technique was used and then the scale was validated with a sample of 343 parents with children aged 0-72 months. The test-retest method, Cronbach's alpha coefficient, Split-half analysis, and item analysis methods were used to determine the reliability of the scale, factor analyses were run to determine construct validity. Explanatory Factor Analysis and Confirmatory Factor Analysis were applied to assess construct validity. RESULTS: Cronbach's alpha coefficient was measured as .84. The Spearman-Brown coefficient was .82 and the Guttman Split-half coefficient was .81. According to the item-total correlation and Cronbach's alpha values when the item was deleted, no item was deleted from the scale. The intraclass correlation coefficient between the test-retest measurements was .79. The three-factor structure consisting of 15 items explained 51.6% of the total variance. As a result of the confirmatory factor analysis, a sufficient fit of the model to the model proposed in the original version of the scale was evident (χ2/sd=2.214, RMSEA=.06). CONCLUSION: The Turkish version of the PACV is a valid and reliable scale and can be used to identify parental attitudes toward childhood vaccines.

[Validation of a belief scale regarding adherence to iron supplementation treatment in mothers of children with anemia]. / Validación de una escala de creencias sobre la adherencia al tratamiento con suplementos de hierro en madres de niños con anemia.

Introduction: Introduction: anemia in children can cause cognitive and motor deficits that can lead to difficulties in academic performance, physical endurance, affecting health and well-being Objective: to develop and validate a scale of beliefs about adherence to iron supplementation treatment in mothers of children with anemia (SBAIST) living in a high altitude region of Peru. Methods: a cross-sectional study was conducted in 192 mothers of children with anemia living in a high altitude region of Peru. The Health Belief Model (HBM) was used to develop and validate the SBAIST. Expert judgment analysis (Aiken's V) was used for content validity and exploratory factor analysis for construct validity. Reliability was determined by internal consistency. Results: for content validity, Aiken's V test showed concordant values for relevance (0.60 to 0.90), relevance (0.75 to 0.95), clarity (0.80 to 0.90) and total scale (0.75 to 0.92). Cronbach's alpha values per question ranged from α = 0.70 to 0.81, and for total scale was α = 0.75. The exploratory factor analysis (EFA) reflected Kaiser-Meyer-Olkin (KMO) values of 0.733, Bartlett's test of sphericity indicated a value of 968.680 (p < 0.001). The eigenvalues in the five dimensions reflected values from 1.05 to 4.03. The percentage of variance for factor 1 (barriers = 33.58 %), factor 2 (severity = 12.61 %), factor 3 (action cues = 10.78 %), factor 4 (barriers = 8.07 %), factor 5 (susceptibility = 7.63 %), and for the total scale was 74.12 %. Conclusion: HBM is a useful tool that allowed validation of the scale of beliefs about adherence to iron supplementation treatment in mothers of children with anemia living at high altitude in Peru.

Introducción: Introducción: la anemia en los niños puede provocar deficiencias cognitivas y motoras que pueden conducir a dificultades en el rendimiento académico y la resistencia física, afectando a la salud y el bienestar. Objetivo: desarrollar y validar una escala de creencias sobre la adherencia al tratamiento con suplemento de hierro en madres de niños con anemia (ECATSH) que viven en una región de altitud del Perú. Métodos: se efectuó un estudio transversal en 192 madres de niños con anemia que viven en una región de elevada altitud del Perú. Se utilizó el modelo de creencias de salud (MCS) para desarrollar y validar la ECATSH. Para la validez del contenido se utilizó el análisis de juicio de expertos (V de Aiken) y para la validez del constructo, el análisis factorial exploratorio. La confiabilidad se determinó por consistencia interna. Resultados: en la validez del contenido, la prueba V de Aiken reflejó valores concordantes para la pertinencia (0,60 a 0,90), relevancia (0,75 a 0,95), claridad (0,80 a 0,90) y la escala total (0,75 a 0,92). Los valores de la alfa de Cronbach por pregunta oscilaron desde α = 0,70 hasta 0,81, y para la escala total fue de α = 0,75.

Validity, reliability and clinical utility of mental disorders: The case of ICD-11 schizophrenia.

Diagnostic classification systems categorise mental psychopathology in mental disorders. Although these entities are clinical constructs developed by consensus, it has been pointed out that in practice they are usually managed as natural entities and without evaluating aspects related to their nosological construction. The objectives of the study are to review a) the conceptualisation of mental disorders, b) the indicators of validity, reliability and clinical utility, and c) the values ​​of these indicators in ICD-11 schizophrenia. The results show that mental disorders are conceptualised as discrete entities, like the diseases of other areas of medicine; however, differences are observed between these diagnostic categories in clinical practice. The reliability and clinical utility of mental disorders are adequate; however, the validity is not yet clarified. Similarly, ICD-11 schizophrenia demonstrates adequate reliability and clinical utility, but its validity remains uncertain. The conceptualisation of psychopathology in discrete entities may be inadequate for its study, therefore dimensional and mixed models have been proposed. The indicators of validity, reliability and clinical utility enable us to obtain an accurate view of the nosological state of mental disorders when evaluating different aspects of their nosological construction.

Measurement of coronaphobia in older adults: Validation of the Spanish version of the Coronavirus Anxiety Scale.

BACKGROUND AND OBJECTIVE: The Coronavirus Anxiety Scale (CAS) is an instrument that measures the severity of anxiety due to COVID-19 or coronaphobia. In the context of the COVID-19 pandemic, older adults are the most vulnerable age group; therefore, the aim of the study was to evaluate the psychometric properties of the CAS in this group. MATERIALS AND METHOD: 274 Peruvian older adults participated (Mage=67.86; SD=6.34, 64.6% women). In addition to the CAS, the 2-item Patient Health Questionnaire (PHQ-2), and 2-item Generalized Anxiety Disorder Scale (GAD-2) were applied. Confirmatory Factor Analysis (CFA) was used to assess the factor structure of the CAS and Item Response Theory was used to analyze item characteristics. A sequence of hierarchical variance models was used to evaluate the measurement invariance of the CAS according to age. To assess reliability, Cronbach's alpha coefficient (α) and the omega coefficient (ω) were used. The correlations between the CAS score and the scores of the PHQ-2 and GAD-2 scales were calculated with Pearson's correlation coefficient (r). RESULTS: The results of the CFA indicated that the unidimensional model of the CAS fitted the data adequately and showed very good reliability (α and ω≥.83). Likewise, all items provided high information and adequate discrimination, which allowed for better detection of average and high levels of coronaphobia in the older adult population. However, the CAS did not show evidence of being strictly invariant between older adults aged 60-65 years and 66-86 years. The CAS showed significant correlations with anxiety (r=.72; [95%CI: .66, .87] p<.01) and depression (r=.53; [95%CI: .43, .76] p<.01). CONCLUSION: The CAS in Spanish shows evidence of validity based on internal structure, convergent and divergent validity, as well as an adequate reliability estimate to assess coronaphobia in older adults. The CAS can be used to detect average and high levels of coronaphobia in the older adult population.

Inter-rater reliability of the measurement of diaphragmatic excursion and fraction of diaphragmatic thickening by ultrasonography in healthy volunteers.

BACKGROUND AND OBJECTIVE: To determine the inter-rater reliability in the ultrasonographic (US) measurement of the diaphragmatic excursion (DE) and the diaphragm thickness fraction (DTF) performed by non-medical health professionals in healthy people. PARTICIPANTS AND METHODS: Prospective observational study in a third level hospital in Cali, Colombia. Measurements were made to 30 healthy volunteers chosen by convenience sampling, without a history of lung diseases, with ages between 18-60 years. A pilot test was previously carried out with 8 healthy volunteers. US measurements of DE, and DTF were based on previously published protocols. Each assessor independently observed several cycles of normal quiet breathing for 3min to establish a baseline. The Intraclass Correlation Index (ICC) was used to evaluate the inter-rater reliability in the measurements of DE and DTF, with 95% confidence intervals and a p<0.05. RESULTS: Substantial agreement was identified in the measurement of DE in the splenic and hepatic windows because the ICC was greater than 0.6 (p<0.05). The measurement of the DTF in the hepatic window showed slight agreement in both 2D and M modes (p>0.05). In the splenic window, the measurement of the DTF in the 2D mode was found to be moderate agreement and for the M mode a slight agreement was found (p>0.05). CONCLUSIONS: The diaphragmatic US constitutes a reproducible method with acceptable inter-rater reliability for the measurement of inspiratory/expiratory thickness, and with little reliability for the measurement of DTF.

Reliability of the Gross Motor Function Measure-66 scale in the evaluation of children with cerebral palsy: validation for Colombia.

BACKGROUND: Infantile cerebral palsy is the leading cause of physical disability in childhood and generates different alterations in motor development that prevent the child's independence. The Gross Motor Function Measure (GMFM) scale is considered the gold standard for this measurement in children with infantile cerebral palsy. In Colombia, its use is delayed due to its original language (English) and no studies on its validity in this specific field. This study aimed to determine whether cultural equivalence allows maintaining the reliability characteristics of the instrument to favor its use in the clinical setting. METHODS: We conducted a cross-sectional study that included 330 children with infantile cerebral palsy from three departments of Colombia, to whom the GMFM-66 scale was applied. Reliability was evaluated from interobserver consistency by estimating intraclass correlation coefficients and internal consistency with the omega coefficient (w) or McDonald's test. RESULTS: The scale demonstrates consistency and stability in its measurements in terms of reliability. The internal consistency was satisfactory only for the first dimension, Lying and rolling (w = 0.91). For the other dimensions, the w-value was always > 0.95. Good agreement was found among the experts in 83.3% of the items and dimensions evaluated. CONCLUSIONS: The GMFM-66 scale in Spanish and for the Colombian context demonstrates good psychometric properties and provides a better understanding of the motor development of children with infantile cerebral palsy so that it can be recommended for use in the Colombian context.

INTRODUCCIÓN: La parálisis cerebral infantil es la principal causa de discapacidad física en la infancia y genera diferentes alteraciones en el desarrollo motor que impiden la independencia del niño. La escala de Medición de la Función Motora Gruesa (GMFM) se considera el método de referencia para esta medición en niños con parálisis cerebral. En Colombia, su uso está rezagado por el lenguaje original (inglés) y la carencia de estudios sobre su validez en este contexto. El objetivo de este estudio fue determinar si la equivalencia cultural permite mantener las características de confiabilidad del instrumento para favorecer su uso en el ámbito clínico. MÉTODOS: Se llevó a cabo un estudio transversal que incluyó 330 niños con parálisis cerebral infantil de tres Departamentos de Colombia, a quienes se aplicó la escala GMFM-66. Se evaluó la confiabilidad desde la consistencia interobservador mediante la estimación de coeficientes de correlación intraclase y la consistencia interna con el coeficiente omega (w) o prueba de McDonald. RESULTADOS: En términos de confiabilidad, la escala demuestra consistencia y estabilidad en sus mediciones. La consistencia interna fue satisfactoria únicamente para la primera dimensión, Decúbito y rolado (w = 0.91). Para las demás dimensiones, el valor de w siempre fue > 0.95. Se encontró un buen acuerdo entre los jueces en el 83.3% de los ítems y las dimensiones evaluadas. CONCLUSIONES: La GMFM-66 en español y para el contexto colombiano demuestra buenas propiedades psicométricas y proporciona una mejor comprensión del desarrollo motor de los niños con parálisis cerebral infantil, por lo que se puede recomendar su uso en el contexto colombiano.

Single item to assess for worry for cancer: Initial evidence of validity and reliability.

OBJECTIVE: To translate into Spanish and evaluate the evidence of content validity, construct validity and reliability of the Cancer Worry Chart as a single item measure of worry for cancer. METHOD: The Spanish translation of the Cancer Worry Chart was done with the back-translation procedure. The participants were 165 healthy people with a family history of cancer who responded to the Cancer Worry Chart and the Cancer Worry Scale (CWS). RESULTS: Translation back-translation allows a Spanish version of the Cancer Worry Chart whose content is clear, coherent and relevant (V>.70). Evidence of construct validity is reported based on 3 criteria: (a) an adequate adjustment of the one-dimensional model formed by the Cancer Worry Chart and the items of the CWS performed with the structural equations method (χ2S-B=23.38; df=14; χ2S-B/df=1.67; CFI=.988; RMSEA=.064); (b) a significant correlation between the Cancer Worry Chart and the CWS (r=.76 [IC95%: .68-.90]); (c) ascending averages in the CWS score as the groups formed by each response option of the Cancer Worry Chart express a greater degree of worry (F=55.72; p=.000; ω2=.57). The reliability of the Cancer Worry Chart is above what is recommended (αsingle item=.84). CONCLUSION: The Spanish version of the Cancer Worry Chart showed satisfactory evidence of content validity, construct validity and reliability to measure, briefly, quickly and generally, the worry for cancer in healthy people with a family history of cancer.

Scale of Concern about COVID-19 Infection in Peruvian Health Care Workers. / Escala de preocupación por el contagio de la COVID-19 en personal de la salud peruano.

INTRODUCTION: The global SARS-CoV-2 pandemic has generated concern about contagion, especially among healthcare workers who are on the front line. OBJECTIVE: To design and analyse the evidence of content validity, internal structure and reliability of a measure of concern about the spread of COVID-19 among Peruvian healthcare workers. MATERIAL AND METHODS: Quantitative study and instrumental design. The scale was administered to 321 health science professionals (78 males and 243 females), whose ages ranged from 22 to 64 years (38.12±9.61). RESULTS: Aiken's V-coefficient values were statistically significant. An exploratory factor analysis was performed which indicated the existence of a single factor, and confirmatory factor analysis (CFA) confirmed a satisfactory six-factor model. The CFA solution obtained adequate fit indices (RMSEA=0.079; p=0.05; TLI=0.967; IFC=0.980; GFI=0.971, and AGFI=0.931), and showed good internal consistency based on Cronbach's alpha coefficient (α=0.865; CI 95%, 0.83-0.89). CONCLUSIONS: The scale of concern for COVID-19 infection is a valid and reliable brief measure that can be used for research and professional purposes.

Confirmatory factor analysis of the family APGAR questionnaire.

INTRODUCTION: In Colombia, the family APGAR questionnaire is often used to evaluate family function. However, there is no confirmatory factor analysis (CFA) to corroborate the proposed one-dimensional structure in Colombian adolescent students. OBJECTIVE: To perform CFA on the APGAR family questionnaire in high-school students of Santa Marta, Colombia. METHOD: A total of 1462 students of tenth and eleventh grade of official and private schools completed the family APGAR questionnaire. Students between 13 and 17 years old (M = 16.0, SD = 0.8) were included, of which 60.3% were female, and 55.3% were tenth grade students. The χ2, RMSEA, CFI, TLI and SMSR were estimated in the CFA. The internal consistency of the dimension was calculated with Cronbach alpha and McDonald omega coefficients. RESULTS: In the CFA the indexes were χ2 = 9.11, df = 5, P = 0.105; RMSEA = 0.024 (CI90%, 0.000-0.048), CFI = 0.998, TLI = 0.996, and SMSR = 0.009. Cronbach alpha coefficient was 0.819 and McDonald omega, 0.820. CONCLUSIONS: The one-dimensional structure of the APGAR family scale is confirmed in high-school students of Santa Marta, Colombia. This questionnaire is reliable and valid for the measurement of family function in school-aged adolescents.

Reliability of a specific questionnaire to evaluate quality of life in people with osteoarthritis. / Confiabilidad de un cuestionario específico para evaluar calidad de vida en personas con osteoartritis.

OBJECTIVES: The aim of this study was to determine the reliability of The Osteoarthritis Knee and Hip Quality of Life questionnaire in a Columbian older adult population with knee and hip osteoarthritis. METHODS: The methodological approach of this study was quantitative, with a cross-sectional design. Respondents completed the questionnaire with a period of 5 to 8 days between measurements. The psychometric properties of reproducibility, internal consistency and level of agreement of the questionnaire were determined using the intraclass correlation coefficient, Cronbach's alpha coefficient and Bland-Altman graphical analysis, respectively. RESULTS: Sixty-two older adults with osteoarthritis of the knee and hip aged between 57 and 82 responded to the questionnaire. Almost perfect reproducibility (CCI=.89) was found for the domain of physical activity, and substantial reproducibility (CCI=.62-.77) for the domains of pain, mental health and activities. A very satisfactory internal consistency was also obtained for the domains of mental health and physical activity (alpha=.90-.94), while that for pain was adequate (alpha=.89). As soon as the level of agreement was established, the mean of the differences in the domains of physical activity, main and mental health was -7.0, -8.0 and -6.9 points, respectively. DISCUSSION AND CONCLUSIONS: The Osteoarthritis Knee and Hip Quality of Life questionnaire showed good psychometric properties principally in the domains of physical activity, pain and mental health. This questionnaire can be used in the clinical setting, but requires adjustment to be used in research.
