Validation of the health literacy scale in patients with hypertension in Mexico.

INTRODUCTION: Health literacy integrates skills around health care. The measurement of health literacy is relevant for proposing improvement interventions. The European HLS-EU-Q16 scale allows to comprehensively evaluate health literacy, but its psychometric properties have not been assessed in Mexico. OBJECTIVE: To validate the HLS-EU-Q16 scale in patients with hypertension in Mexico. METHODS: A validation study of a measuring instrument was carried out. The construct was evaluated by means of factor analysis; internal consistency, using Cronbach's alpha; and test-retest reliability, using intraclass correlation coefficient (ICC). The information was collected by interviewing 349 patients with hypertension in a family medicine unit of the Mexican Institute of Social Security, from April to June 2022. RESULTS: In 23.8% of the patients, health literacy was inadequate; in 44.4%, problematic; and in 31.8%, sufficient. The scale was found to retain 12 items and two factors (HLS-EU-Q12M). Cronbach's alpha was 0.83, and ICC was 0.94. CONCLUSION: The HLS-EU-Q12M scale in Mexican Spanish is a valid instrument for assessing health literacy in adults with hypertension.

[Validation of the knowledge and attitudes of health professionals in the Living Will Declaration process]. / Validación del cuestionario de conocimientos y actitudes de los profesionales sanitarios en el proceso de declaración de voluntades vitales anticipadas.

OBJECTIVE: Evaluate the validity and reliability of the knowledge and attitudes of health professionals questionnaire on the Living Will Declaration (LWD) process. DESIGN: Cross-sectional study structured into 3 phases: (i)pilot questionnaire administered with paper to assess losses and adjustment problems; (ii)assessment of the validity and internal reliability, and (iii)assessment of the pre-filtering questionnaire stability (test-retest). LOCATION: Costa del Sol (Malaga) Health Area. January 2014 to April 2015. PARTICIPANTS: Healthcare professionals of the Costa del Sol Primary Care District and the Costa del Sol Health Agency. There were 391 (23.6%) responses, and 100 participated in the stability assessment (83 responses). MAIN MEASUREMENTS: The questionnaire consisted of 2 parts: (i)Knowledge (5 dimensions and 41 items), and (ii)Attitudes (2 dimensions and 17 items). RESULTS: In the pilot study, none of the items lost over 10%. In the evaluation phase of validity and reliability, the questionnaire was reduced to 41 items (29 of knowledge, and 12 of attitudes). In the stability evaluation phase, all items evaluated met the requirement of a kappa higher than 0.2, or had a percentage of absolute agreement exceeding 75%. CONCLUSIONS: The questionnaire will identify the status and areas for improvement in the health care setting, and then will allow an improved culture of LWD process in general population.

Adaptation and validation of the Spanish version of the Actinic Keratosis Quality of Life questionnaire. / Adaptación y validación de la versión española del cuestionario Actinic Keratosis Quality of Life (AKQoL).

BACKGROUND AND OBJECTIVE: While there are questionnaires for evaluating the effects of skin cancer on patient quality of life, there are no specific questionnaires available in Spanish for evaluating quality of life in patients with actinic keratosis. The aim of this study was to translate and culturally adapt the Actinic Keratosis Quality of Life (AKQoL) questionnaire into Spanish. PATIENTS AND METHODS: The original questionnaire was translated into Spanish following the guidelines for the cross-cultural adaptation of self-report measures. Several measures of general reliability and validity were calculated, including Cronbach α for internal consistency and the Spearman rank-order correlation coefficient and a Bland-Altman plot for test-retest reliability. To test concurrent validity, we used the Pearson correlation coefficient to measure the correlation between AKQoL and Skindex-29 scores. RESULTS: The final version of the questionnaire was administered to 621 patients with actinic keratosis, who scored a mean (SD) of 5.25 (4.73) points (total possible score, 0-25). The Cronbach α reliability coefficient analysis was 0.84. The correlation between the mean (SD) score on the Skindex-29 (1.87 [4.07]) and on the AKQoL (1.97 [2.98] was 0.344 (P=.002, Spearman's rho), with a proportion of shared variance of 11.8%. CONCLUSIONS: The translation, cross-cultural adaptation, and validation of the original AKQoL produced a reliable, easily understandable questionnaire for evaluating the impact of actinic keratosis on the quality of life of patients in our setting.

[Psychometric validation of the Yale Food Addiction Scale for Children (YFAS-C) in Spanish in a Mexican population]. / Validación psicométrica de la escala Yale Food Addiction Scale for Children (YFAS-C) al idioma español en población mexicana.

Introduction: Introduction: Mexico is one of the countries with the highest prevalence of childhood obesity worldwide. The increase of addictive behaviors at an early age is a possible cause of its development. The Yale Food Addiction Scale for Children (YFAS-C) allows identifying children with food addictive behaviors. Objective: to validate the YFAS-C scale in Spanish in a population sample of Mexican children and adolescents. Material and methods: an exploratory and confirmatory factor analysis was performed. The study sample consisted of 448 children from seven to 14 years of age. The first stage involved translation into Spanish; a second stage involved the solution of questions with discrepancies; then, a reverse translation into the original language and a review by experts on the subject of eating disorders in pediatric population were performed; and in the last stage, a pilot test in order to culturally adapt the instrument and the evaluation of the psychometric properties was carried out. Results: using the principal component extraction method, four components were identified that explained 47.1 % of the sample variance. In the confirmatory factor analysis, it was found that the goodness-of-fit indices met the required values (CFI = 0.906: GFI = 0.932; AGFI = 0.915, SRMS = 0.007 and RMSEA = 0.043). Conclusions: a validated Spanish version of the YFAS-C scale was obtained for Mexican children and adolescents to assess food addiction.

Conclusiones: se obtuvo una versión validada al español de la escala YFAS-C para niñas/niños y adolescentes mexicanos que permitirá evaluar la adicción a la comida.

Cross - cultural adaptation of the Low Vision Quality of life scale.

INTRODUCTION: The quality of life related to visual function is a multidimensional construct that complements the functional assessment of patients with low vision. It shows the individual's perception of the course of ocular disease and its treatment within the framework of a value system and a sociocultural context. This clinical-epidemiological outcome is recognized as objective and valuable. METHODOLOGY: A content validation study was conducted, which involved translating and back-translating the scale to evaluate semantic, idiomatic, conceptual, and experiential equivalence in the resulting version. The study included the participation of 21 individuals, and a quantitative evaluation was performed using Aiken's V coefficient to analyze the scores assigned in the categories of relevance and experiential capacity. RESULTS: The questionnaire presentation was reorganized. The examples were expanded, and some optical aids were mentioned. Additionally, terms were changed to improve comprehension and reduce rudeness. Out of the 25 items, 11 had an Aiken V coefficient of less than 1.0. CONCLUSIONS: The obtained version is comparable to the original questionnaire. However, the idiomatic twists specific to the local context emphasize the need for content validation to ensure correct interpretation and contribute to the updating of the scale.

Development and validation of meta-measurement instruments: A methodological approach.

A valid and reliable nursing assessment is essential for identifying required care and ensuring patient safety. The convenience of conducting a comprehensive assessment of the patient has led to a significant increase in assessment tools that may slow down the process. Nevertheless, the possibility of consolidating various instruments that measure common or similar constructs into a meta-instrument is considered an alternative that could enhance assessment efficiency. A meta-instrument can be defined as a measurement tool that consolidates other instruments based on measuring related constructs and sharing dimensions or items, aiming to achieve a more parsimonious measurement. Literature on such assessment tools is scarce, and there are numerous options for their construction and initial validation. Additionally, it is advisable to confirm their psychometric properties and ensure that they maintain, at the very least, the same diagnostic capacity as the original instruments. This article presents a proposal for the phases to follow in constructing meta-instruments, along with various methodological alternatives that can be employed based on the characteristics of the original instruments and the purpose of creating the meta-instrument. Furthermore, special attention is given to the checklists that should be used to study the psychometric properties and diagnostic capacity of the meta-instruments. Finally, future lines of research and challenges in the development of nursing assessment meta-instruments are discussed.

Attitude towards health promotion in university students. Construction and validation of a scale.

OBJECTIVE: To construct and validate a questionnaire about the attitude of university students toward health promotion. METHOD: A cross-sectional study. A questionnaire of 14 questions was designed and administered to 1486 first-year undergraduates. The principal axes factoring method with oblique rotation was applied and a confirmatory factor analysis was carried out. Reliability was calculated through internal consistency with Cronbach's alpha and item-total correlation for the global scale and its subscales. RESULTS: A 14-item scale was constructed, with two dimensions. Its Cronbach's alpha was 0.872, and 0.852, and 0.718 for its subscales. The adjustment values of the confirmatory factor analysis were adequate. CONCLUSIONS: The attitude towards health promotion scale has shown to have adequate psychometric properties. It is an instrument that will help to detect referents and health assets for future interventions.

Reliability of the Mental Health Nurse Competency Assessment Tool (ECOEnfSM): A pilot study.

AIM: To evaluate the reliability of the ECOEnfSM scale as a tool to assess the professional competencies of Mental Health Nurse Practitioners (MHNP) in their clinical practice. METHOD: A pilot study, observational, descriptive and cross-sectional, focuses on MHNP who have completed their Specialized Health Training Program (SHTP) in Spain. The data were collected by general and collaborators mentors of the Multiprofessional Teaching Units (MTUs). The Mental Health Nursing Competency Assessment Tool (ECOEnfSM) was used, which consists of three subscales and eight Competence Units (CU). A reliability and validity analysis were conducted (Cronbach's alpha and Spearman's correlation coefficient). RESULTS: The Rotation Assessment subscales showed excellent reliability (r > 0.90) with high and very high correlations (r > 0.6) in all UCs with high levels of significance (P < .01). The Annual Assessment subscale showed good reliability (r > 0.80) with a medium and very high correlation (r > 0.4) with high levels of significance (P < .01). All UCs showed a good to excellent consistency (r > 0.80). The "Home Visits" assessment criterion showed heterogeneity of data due to there are few MTUs that fully develop it. CONCLUSION: The ECOEnfSM scale showed very high reliability in MHNP during their training program in Spain. The ECOEnfSM is considered the only objective tool in Spain to assess the professional competencies in this population.

Psychometric properties of the Eating Attitudes Test-26 in Spanish schoolchildren.

INTRODUCTION: Disordered Eating Attitudes and Behaviours (DEABs) can impact both the mental and physical health of children. Early detection is crucial to prevent complications and improve outcomes. The Eating Attitudes Test-26 (EAT-26) is a widely used, cost-effective tool for assessing DEABs. OBJECTIVE: To evaluate the psychometric properties of the EAT-26 by analysing its factor structure, internal consistency, convergent validity, and measurement invariance across sexes in Spanish schoolchildren. METHOD: Validation study in a sample of 718 schoolchildren. The sample was randomly divided into 2 groups, each with 359 participants, and we carried out an exploratory factor analysis (EFA) and a confirmatory factor analysis (CFA) of the instrument. Subsequently, we assessed the internal consistency by means of the ordinal alpha, the convergent validity with the SCOFF questionnaire and the measurement invariance across the sexes. RESULTS: The results of the EFA and CFA supported a multidimensional structure of the EAT comprising 6 factors and 21 items. These factors underlie a second-order model of DEABs. The internal consistency was adequate for most factors. The SCOFF questionnaire showed a moderate convergent validity for most of the EAT-21 factors. We found measurement invariance across the sexes. CONCLUSIONS: The abbreviated EAT-21 scale exhibited modest and promising psychometric properties, making it a suitable instrument for assessing DEABs in both sexes in educational settings.

[Validation of the questionnaire on vaccines and hesitancy to be vaccinated in the Spanish Society of Epidemiology]. / Validación del cuestionario sobre vacunas y reticencia a vacunarse en la Sociedad Española de Epidemiología.

OBJECTIVE: To develop and validate a survey aimed at epidemiologists to measure factors associated with vaccine reluctance. METHOD: Vaccination hesitancy refers to delayed acceptance or refusal of vaccination despite the availability of vaccination services. WHO included vaccination hesitancy among the 10 global health threats in 2019. Within this conceptual framework proposed by WHO, a committee of six experts from the Spanish Society of Epidemiology (SEE) designed a self-administered questionnaire to study factors associated with vaccination hesitancy in epidemiologists. This questionnaire was approved by the SEE Board, and was sent online to all members in 2019. Based on the responses obtained, the following characteristics were validated: face validity, internal validity, construct validity, criterion validity, reliability, as well as the characteristic curves of each item and the information function per item and overall. RESULTS: The final questionnaire showed two well-defined components, perception of vaccines and confidence in the transparency of vaccine data with high degrees of fit in all aspects of validation. Both components have shown that the higher the reluctance to vaccinate the better the questionnaire reports on these aspects. CONCLUSIONS: The study has allowed the development of a validated instrument in Spanish to measure the factors associated with vaccine reluctance among epidemiologists.

[Development and validation of standards for quality units of health centers]. / Desarrollo y validación de estándares para unidades de calidad de centros sanitarios.

OBJECTIVE: In Spain, the Quality Units advise health centres, services and professionals on the methodology of continuous improvement of the quality of care. A system based on good practice standards could provide these units with a tool to improve their results and value their work. The objective was to develop, agree on and validate standards, to properly guide and orient the functions, results and continuous improvement of the Quality Units in health centers. MATERIAL AND METHODS: A qualitative-quantitative, prospective and cross-sectional study was carried out, applying the Metaplan method, the e-Delphi technique and a simulation study. The participants were coordinators of these units, belonging to 14 Spanish Autonomous Communities and distributed in four experts' panels. They agreed on the standards to be used and evaluated the different types of validity. RESULTS: The 204 standards proposed by the scientific committee were reduced to 157 with Metaplan, to 110 with e-Delphi, and to 96 with the committee's final review (87.3% consensus, content validity). The construct validity showed a Cronbach's alpha >0.7 (P<.001); the validity of content was reaffirmed in the simulation workshop (80% "understood" each other, P<.001; and there was "documentary evidence" in 84%, P<.001); face validity was accepted (75% "related to quality dimensions", P<.001); and the validity of the criteria was verified with a sensitivity of 84.2%, a specificity of 98.3%, and a kappa index of 0.84. CONCLUSIONS: Valid standards have been developed for Quality Units in health centers.

Predictive validity of the Clinical Frailty Scale-España on the increase in dependency after hospital discharge.

INTRODUCTION: The frailty present at hospital admission and the stressors to which patients are subjected during their stay may increase dependency at hospital discharge. OBJECTIVES: To assess the predictive validity of the Clinical Frailty Scale-España (CFS-Es) on increased dependency at 3 and 12 months (m) after hospital discharge. METHODOLOGY: Multicentre cohort study in 2020-2022. Including patients with >48 h stay in intensive care units (ICU) and non-COVID-19. VARIABLES: pre-admission frailty (CFS-Es). Sex, age, days of stay (ICU and hospital), dependency on admission and at 3 m and 12 m after discharge (Barthel index), muscle weakness (Medical Research Council Scale sum score <48), hospital readmissions. STATISTICS: descriptive and multivariate analysis. RESULTS: 254 cases were included. Thirty-nine per cent were women and the median [Q1-Q3] age was 67 [56-77] years. SAPS 3 on admission (median [Q1-Q3]): 62 [51-71] points. Frail patients on admission (CFS-Es 5-9): 58 (23%). Dependency on admission (n = 254) vs. 3 m after hospital discharge (n = 171) vs. 12 m after hospital discharge (n = 118): 1) Barthel 90-100: 82% vs. 68% vs. 65%. 2) Barthel 60-85: 15% vs. 15% vs. 20%. 3) Barthel 0-55: 3% vs. 17% vs. 15%. In the multivariate analysis, adjusted for the variables recorded, we observed that frail patients on admission (CFS-Es 5-9) are 2.8 times (95%CI: 1.03-7.58; p = 0.043) more likely to increase dependency (Barthel 90-100 to <90 or Barthel 85-60 to <60) at 3 m post-discharge (with respect to admission) and 3.5 times (95%CI: 1.18-10.30; p = 0.024) more likely to increase dependency at 12 m post-discharge. Furthermore, for each additional CFS-Es point there is a 1.6-fold (95%CI: 1.01-2.23; p = 0.016) greater chance of increased dependency in the 12 m following discharge. CONCLUSIONS: CFS-Es at admission can predict increased dependency at 3 m and 12 m after hospital discharge.

Development and validation of a low-cost laparoscopic simulation box.

INTRODUCTION: The acquisition of laparoscopic technique skills in an operating room is conditioned by the expertise of the tutor and the number of training interventions by the trainee. For students and surgeons to use a laparoscopic simulator to train their skills, it must be validated beforehand. METHODS: A laparoscopic simulator box was designed, along with 6 interchangeable training games. The simulator was validated by a group of 19 experts, physicians with an experience from at least 100 laparoscopic surgeries, and 20 students of 4th to 6th grades of medical school (non-experts). To evaluate its construct validity, time-to-completion and the number of successfully completed games were assessed. We used 11 and 9-item questionnaires to gather information on content and face validity respectively. In both questionnaires, answers were collected through Likert-type scales, scored from 1 to 5. RESULTS: The group of experts required less time and successfully completed more games than the group of non-experts (p < 0.01). The group of non-experts gave a score ≥ 4 points on each of the questions regarding the content validity of the tool, however, the experts rated with a significant lower mean score the need for the simulator to learn the surgical technique (3.68 points; p < 0.01). Regarding the face validity, all items were graded with a score ≥ 4 points except for the question relating to the spatial realism (3.82 points). CONCLUSION: The laparoscopy simulation box and the games were valid means for training surgeons and medical students to develop the skills required for the laparoscopic technique.

Translation and transcultural adaptation of the AS-20 scale to measure quality of life in adults with strabismus in Colombia, a pilot study.

BACKGROUND: Strabismus generates a negative psychosocial impact on adult patients, affecting aspects such as self-perception and quality of life. There is no scale in Colombian Spanish that measures these impacts. OBJECTIVE: To carry out the translation and cross-cultural adaptation of the AS-20 instrument into Colombian Spanish. MATERIALS AND METHODS: Pilot test of a cross-sectional Study for the translation, reverse translation, and cross-cultural the AS-20 instrument from its original language, English, to Colombian Spanish, in adult patients with strabismus in Bogotá, Colombia. RESULTS: 16 patients were assessed. The age range was between 18 and 68 years with a mean age of 41 years. The scale was answered in an average time of 10.62min. Difficulty was reported in three individuals for understanding two items (questions 8 and 14), which were resolved. CONCLUSION: The translation and pilot test of AS-20 scale into Colombian Spanish was carried out, identifying and solving translational difficulties. Is the first step in the cross-cultural adaptation process. Based on the results, the validation and cross-cultural adaptation can be completed in a future study.

CUIDAR-MaPre scale validation: A tool to measure the caregiving competence of mothers of premature infants.

OBJECTIVE: To determine the validity and reliability of the CUIDAR instrument in mothers of premature infants. METHOD: Cross-sectional validation study. The study was conducted in two stages. First stage: literature review, semantic adequacy, and judgement with 7 experts to establish content validity. In the second stage, the psychometric properties of the instrument were evaluated by exploratory factor analysis after its application to 207 mothers of premature infants. RESULTS: In the expert's judgment, the content validity index was higher than 0.8, which indicated adequate representativeness of the items. Agreement between judges was moderate with a Fleiss Kappa of 0.51. The exploratory factor analysis established the adequacy of the sample with a Kaiser-Mayer-Olkin statistic of 0.859 and Bartlett's test of sphericity 2953.9 (p = 0.000). After considering various scenarios, a 7-dimensional, 33-item model explained 57.9% of the variance, with an overall Cronbach's alpha of 0.852 and adequate goodness-of-fit indices. The goodness-of-fit tests allowed us to establish through statistical significance χ2 = 0.01, CFI = 0.92, BIC ≥ 10 and RMSEA = 0.05 indicating that the model has a good fit. CONCLUSIONS: A new model was identified based on the items and dimensions of the CUIDAR instrument, which allows us to assess the competence of mothers to care for their premature children in a valid and reliable way.

[CVS-Q teen©: computer vision syndrome in adolescents and its relationship with digital textbooks]. / CVS-Q teen©: síndrome visual informático en adolescentes y su relación con libros de texto digitales.

OBJECTIVE: To analyse the prevalence and progression of computer vision syndrome in secondary and high school students with the CVS-Q© adapted and validated for adolescents, depending on whether they use textbooks or digital books. METHOD: The CVS-Q© will be adapted by a pilot study in adolescents and a nominal group of visual health specialists, teachers and parents. The resulting version (CVS-Q teen©) will be tested to confirm its quality and applicability and a validation study will be done with visual tests, retest and psychometric analysis. Subsequently, a prospective longitudinal study with four repeated measures will be carried out in adolescents from two secondary schools of San Juan de Alicante (one has replaced textbooks by tablets). Computer vision syndrome will be measured by the CVS-Q teen© with three follow-ups. The prevalence of computer vision syndrome will be analysed according to sociodemographic, visual and digital device use variables. Logistic regression models will be performed, with random effect by student and time of use.

Mental health professionals' attitudes towards mental competency and involuntary commitment in anorexia nervosa: Construction, validation and results of the ACINOVAN questionnaire.

INTRODUCTION: Anorexia nervosa is a serious disorder that causes high rates of morbidity and mortality. Involuntary treatments are only legally admissible if the patient is not competent. However, assessing their capacity can be really complex. This implies that the final decision can be influenced by the individual attitudes of the physician. OBJECTIVE: To create and empirically validate a questionnaire in Spanish that makes it possible to measure the attitude towards capacity and involuntary commitment and compare between categorical groups. METHODS: The sample consisted of 338 mental health professionals. The items were validated by groups of experts. An exploratory factor analysis and group comparisons were carried out. RESULTS: Favourable evidence was obtained of a 13-item model consisting of three factors: pro-intervention, lack of competence and chronicity. Professionals tend to believe in the lack of capacity and the need for involuntary interventions, as well as differential suitability due to chronicity. Support prior to involuntary interventions was significantly related to the pro-intervention and absence of capacity factors, and training in bioethics to chronicity. CONCLUSIONS: The resulting instrument is valid and reliable. Its use can be useful to professionals, patients and society.
