RESUMO
Dentro de la práctica clínica, así como en la salud poblacional, es habitual utilizar cuestionarios que permiten evaluar condiciones o variables que no son directamente observables. No obstante, la construcción y validación de estos instrumentos o cuestionarios suele ser poco conocida. El objetivo de esta revisión narrativa es sintetizar de manera general el proceso de construcción y validación de estos cuestionarios, para así tener una mejor comprensión de este proceso, de los aspectos que se evalúan y de la mejor forma de utilizarlos. La validación de cuestionarios corresponde a un proceso de análisis de este, cuya finalidad es medir una variable latente o constructo, así como sus dimensiones, las que no pueden ser observadas directamente. Una variable latente puede ser inferida a través de un conjunto de atributos específicos que forman parte de ella, como los ítems de un cuestionario y que sí son observables. En este artículo se abordan de manera teórica los conceptos fundamentales de validación de cuestionarios o test, variables latentes o constructos, estudio de la confiabilidad y de la validez, así como los factores que afectan a estas dos últimas características, a través de una revisión narrativa. En el texto, se presentan ejemplos sobre estos conceptos.
In clinical practice and population health, it is common to use questionnaires to assess conditions or variables that are not directly observable. However, the construction and validation of these instruments or questionnaires are often poorly understood. This narrative review aims to summarize in a general way the process of construction and validation of these questionnaires in order to have a better understanding of this process, the aspects that are evaluated, and the best way to use them. The validation of questionnaires corresponds to a process of analysis of the questionnaire, aiming to measure a latent variable and its dimensions, which cannot be observed directly. A latent variable can be inferred through a set of specific attributes that are part of it, such as the items of a questionnaire, which are observable. Through a narrative review, this article addresses the fundamental concepts of questionnaire or test validation, latent variables or constructs, reliability and validity studies, and the factors that theoretically affect the latter two characteristics. Examples of these concepts are presented in the text.

RESUMO
Abstract Objectives The aims of this study are to make the Turkish validity and reliability of the scale that explain why caffeine intake. Additionally, it is crucial to highlight that the adaptation of the scale involved a confirmatory factor analysis (CFA) to validate its structure and the need for this adaptation in the Turkish context. Materials and methods The study was carried out with a total of 200 university students, comprised of 93.5% female and 6.5% male participants, with a mean age of 21.74 ± 6.15 years who were actively studying in the faculties of the universities who accepted to participate voluntarily in the study were included. The Turkish version of the Motives for Caffeine Consumption Questionnaire (MCCQ) scale and the MCCQ was used as the data collection tools. To evaluate the statistical analysis findings, the margin of error was taken as 5%. The entire application was carried out with the R-project software. CFA was used to test the adaptation of the MCCQ scale from English to Turkish. Results The alpha internal consistency coefficient for the whole scale was calculated as 0.959. Just like the original scale, the Turkish version shows a six-factor structure: habit, alertness, mood, social, taste, and symptom management. In MCCQ-TR, it showed a low level of positive correlation with Yale Food Addiction Scale (YFAS). For the final scale with 23 items and 6 sub-dimensions, it was determined that the fit indices were at an acceptable level, and the internal consistency was highly reliable for all sub-dimensions and the total scale. Conclusions It has been determined that the Turkish version of the MCCQ is a valid and reliable measurement tool to operationalize the motives of caffeine consumption and to reveal possible differences in the motives regarding gender, age, and the type of caffeinated products consumed. The use of CFA in adapting the scale ensures the robustness of the structural validity in the Turkish context, making this adaptation a valuable contribution to the field.

ObjectiveTo develop a self-assessment questionnaire for menstrual abnormalities and test its reliability and validity. To provide an assessment tool for self-identification of abnormal menstruation in young women and to investigate the health seeking situation of abnormal menstruation in the population. MethodsFifteen physicians with clinical experience were invited to participate in the Delphi expert consultations. Medical indications for menstrual abnormalities were constructed and questionnaires were formed based on domestic and international literature， expert meetings and 2 rounds of Delphi expert consultations. A whole-group sampling was used to select 923 female college students from a medical school in Shanghai for the survey， and 306 of them were retested. The internal consistency， retest correlation， researcher-investigator evaluation correlation， and structural and response validity of the questionnaire were examined. ResultsThe questionnaire formed 6 dimensions with 17 indications. The positive coefficients for the two rounds of consulting experts were >90%. The mean authority coefficient was 0.857. The Kendall W coordination coefficient was 0.465 and 0.455， respectively （P<0.001）. The questionnaire Cronbach's alpha coefficient was 0.622. The retest correlation coefficient was 0.459. The correlation coefficient between the researcher's score and the respondents' self-assessment was 0.562. The five common factors extracted by factor analysis were consistent with the structure of the questionnaire， and the cumulative contribution of variance was 54.4%. Total questionnaire scores were moderately to highly correlated with each dimension score （0.409 to 0.699）. There was low correlation between the dimensions （-0.002 to 0.203）. Girls who had sought medical care had higher scores on the total questionnaire， category A， category B， cycle dimension， menstrual dimension， and dysmenorrhea/PMS dimension than girls who had not sought medical care （P<0.01）， and the difference between the two groups in menstrual volume dimension scores was not statistically significant. ConclusionThe self-assessment questionnaire for menstrual abnormalities developed in this study has acceptable reliability， good structure validity and response validity. It can provide a self-examination tool and medical consultation guidance for young women with abnormal menstruation.

RESUMEN Introducción: El uso de la mascarilla es indispensable para reducir la propagación de la COVID-19, pero, un porcentaje importante de personas se rehúsan a su uso. Es posible que las creencias jueguen un rol sustancial en la aceptación o rechazo de su uso. Sin embargo, se carece de una escala para evaluar las creencias sobre el uso de mascarillas para prevenir el contagio de la COVID-19. Objetivo: Traducir y determinar las evidencias de validez, de estructura interna y confiabilidad del autoinforme de creencias sobre el uso de las mascarillas. Métodos: El autoinforme de creencias sobre el uso de las mascarillas fue administrado a 1 218 personas de diferentes provincias del Perú (Medad = 27,4 años, DE = 12,6), elegidas de forma no probabilística. El instrumento fue sometido a un proceso de doble traducción del inglés al español y viceversa; además, mediante el programa Proyecto Jamovi versión 1.6, se determinó la estructura interna con análisis factorial (exploratorio y confirmatorio) y finalmente se estimó la confiabilidad. Resultados: El análisis factorial exploratorio identificó cuatro factores emergentes que explicaron el 53,7 % de la varianza. El modelo fue verificado y obtuvo índices de ajuste aceptables (χ² = 154 gl = 46; p < 0,01; CFI = 0,96; TLI = 0,942; RMSEA = 0,602). Además, se apreciaron cargas factoriales estandarizadas mayores a 0,30. Conclusión: La versión en español del autoinforme de creencias sobre el uso de las mascarillas muestra evidencias de validez, de estructura y confiabilidad por consistencia interna adecuadas.
ABSTRACT Introduction: The use of a mask is essential to reduce the spread of COVID-19, however, a significant percentage of people refuse to use it. Beliefs may play an important role in accepting or rejecting their use. Objective: To translate and determine the evidence of validity of internal structure and reliability of the self-report of beliefs about the use of masks. Methods: The self-report of beliefs about the use of masks was administered to 1218 people from different provinces of Peru (M age = 27,4 years, SD = 12,6), chosen in a non-probabilistic way. The instrument was subjected to a process of double translation from English to Spanish and vice versa; In addition, using the Jamovi Project version 1.6 program, the internal structure was determined with factor analysis (exploratory and confirmatory), and finally reliability was estimated. Results: The exploratory factor analysis identified four emerging factors that explained 53.7% of the variance. The model was verified and obtained acceptable fit indices (χ² = 154 gl = 46; p < 0,01; CFI = 0,96; TLI = 0,942; RMSEA = 0,602). In addition, standardized factor loadings greater than 0,30 were observed. Conclusions: The Spanish version of the self-report of beliefs about the use of masks shows evidence of validity of structure and reliability due to adequate internal consistency.
RESUMO
Resumen: Introducción: la medición precisa de la actividad física (AF) es clave para analizar su asociación con resultados de salud. Sin embargo, en Uruguay no existen estudios que comparen diferentes métodos para determinar la AF en adultos. El objetivo de este estudio fue analizar la confiabilidad del Cuestionario Internacional de Actividad Física (IPAQ) en estudiantes universitarios uruguayos y evaluar su validez concurrente en comparación con la AF basada en dispositivos. Método: 54 estudiantes universitarios de educación física completaron el IPAQ (versión larga) en dos ocasiones con 7 días de diferencia y utilizaron acelerómetros GeneActiv durante ese período. La confiabilidad se evaluó a través del Coeficiente de Correlación Intraclase (ICC) y se utilizó el análisis de Bland-Altman para determinar la validez concurrente. Resultados: todos los dominios de AF mostraron niveles moderados de ICC. El transporte (ICC = 0,64), el tiempo libre (ICC = 0,58), y la AF total (ICC = 0,53) fueron los dominios con niveles moderados más altos. El total de minutos de AF evaluados a través del IPAQ en las dos ocasiones reportó un promedio de 773 minutos de diferencia (IC 95% 362,88-1.184,01). La diferencia de minutos de AF entre la evaluación con el IPAQ y con los acelerómetros es de 752 minutos (IC 95% 418,05-1.087.16). Conclusiones: el IPAQ sobreestima la AF respecto al acelerómetro en estudiantes universitarios uruguayos, sin embargo fue más confiable al considerar dominios de transporte y tiempo libre para los participantes que reportaron realizar un promedio menor a 400 minutos de AF semanal.
Summary: Introduction: precise measurement of physical activity (PA) is key to analyze its association with health results. However, there are no studies in Uruguay comparing the different methods to determine PA in adults. The study aims to analyze the reliability of the International Physical Activity Questionnaire (IPAQ) in Uruguayan university students and to assess its validity by comparing it to device-based monitoring PA. Method: 54 Physical Education university students completed the IPAQ (long version) on 2 occasions with a 7 day difference using GeneActive accelerometers during that period. Reliability was assessed with the Intraclass Correlation Coefficient (ICC) and the Bland-Altman analysis was used to determine concurrent validity. Results: all PA domains evidenced moderate ICC levels. Transport (ICC= 0.64), free time (ICC= 0.58) and total PA (ICC= 0.53) were the domains with the highest moderate levels. The total number of minutes of PA assessed by IPAQ reported an average of a 773 minutes difference (CI 95%: 362.88; 1184.01). Difference of PA in minutes, considering the assessment with the IPAQ and the accelerometers is 752 minutes (CI 95%: 418.05; 1087.16). Conclusions: the IPAQ overestimates the PA when compared to the accelerometer in Uruguayan university students. However, it was more reliable when considering the transport and free time domains for participants who reported an average physical activity under 400 minutes per week.

Background: A quality of life (QoL) assessment tool needs to be translated and validated in the language of the participants to whom it is administered. Therefore, the oral health impact profile-14 (OHIP-14) scale, developed originally in English, has been translated into different languages like Hindi, Gujrati, etc. The Marathi version of OHIP-14 will be useful to assess in regions where the Marathi language is prominently spoken. Thus, the present study was carried out to translate and validate the Marathi version of the OHIP-14 instrument to measure the oral health-related quality of life. Aims & Objectives: To translate and validate the English Version of the OHIP-14 instrument in the Marathi Language. Materials and Methods: This was a descriptive cross-sectional study in which 128 participants were selected through a convenient sampling method. The English version of the OHIP-14 was translated using the forward-backward translation technique, and participants were given English and the Marathi versions of the OHIP-14 questionnaire. The filled questionnaires were subjected to statistical analysis. Result: The difference in mean scores was not statistically significant(p=0.828). Pearson’s correlation coefficient test was 0.999, suggesting that the translated Marathi version is highly correlated with the original English version. Conclusion: The Marathi version of OHIP-14 is a valid, and reliable instrument for assessing QoL among the population who speak Marathi.

Conclusions:The reliability and validity of the cultural competency assessment scale for geriatric clinical nurse specialists are good and can be used to evaluate the cultural competency of geriatric clinical nurse specialists.
RESUMO
Objective:To explore the construction of evaluation index system of core competence of imaging specialized nurses and analysis of reliability and validity test.Methods:Firstly, a research group was established to consult the relevant literature. After repeated discussion among the members of the research group, imaging specialized nurses were invited to discuss, modify and improve the framework of the evaluation index system, and an expert consultation questionnaire for the evaluation index system of the core competence of imaging specialized nurses was formulated. Through two rounds of expert consultation, the core competence evaluation index system of imaging specialized nurses was constructed, and a questionnaire was compiled based on the constructed index system. Questionnaire survey method was used to verify the rationality and scientificity of the core competence evaluation index system of imaging specialized nurses constructed in this study.Results:The evaluation index system of core competence of imaging specialized nurses included 3 first-level indexes, 20 second-level indexes and 48 third-level indexes. The overall Cronbach's α coefficient of the evaluation index system was 0.972. The Cronbach's α coefficients of the theoretical knowledge of imaging specialized nursing, nursing practice skills of imaging specialized nurses and related abilities were 0.915, 0.934 and 0.924 respectively. The overall content validity index (S-CVI) of the index system was 0.977, and the CVI of each item (I-CVI) was 0.812-1.000. The overall correlation coefficient of the first-level indexes and index system was 0.800-0.936 ( P < 0.05), the correlation coefficient of the secondary indexes and the corresponding primary indexes was 0.562-0.972 ( P<0.05), and the correlation coefficient of the third-level indexes and the corresponding first-level index was 0.362-0.914 ( P<0.05). Conclusion:The constructed questionnaire for evaluation index of core competence of imaging specializied nurses has good reliability and consistent internal structure, and has good feasibility, reliability, rationality and scientificity, which provides a theoretical basis and practical guide for the cultivation, assessment and evaluation of core competence of imaging specialized nurses.
RESUMO
@#Introduction: The study’s objective was to validate a Malay language translated questionnaire on end-of-life care to be used among nurses practicing in critical care areas. Methods: The English language questionnaire underwent forward and backward translations by four experts. The translated Malay language questionnaire was pilot tested on 30 subjects and revised accordingly. The validation of the revised questionnaire was carried out on 250 nurses. The reliability of the translated questionnaire was checked. Cronbach alpha value of at least 0.70 suggests adequate internal consistency. The validity of the questionnaire was explored using Confirmatory Factor Analysis (CFA) and model fit tests were run to achieve fit test specific cut off values. The CFAs were run repeatedly with iterative item reductions until acceptable goodness of fit for the model was achieved. Results: All domains of the translated questionnaire showed reasonable to excellent reliability (Cronbach Alpha 0.687 to 0.922). Multiple CFAs were run and 13 out of 46 items were excluded, and the final model fit improved substantially with the indices were within the acceptable threshold of good or reasonably fit, cut off values are in brackets [Chi-Square statistics 1.635 (≤ 2.0), Root Mean Square Error of Approximation 0.050 (< 0.05), Standardised Root Mean Square Residual 0.059 (≤ 0.08), Comparative Fit Index 0.911 (0.90-0.94), Tucker Lewis Index 0.900 (0.90-0.94), Akaike Information Criteria 13024, Bayesian Information Criteria 13334]. Conclusion: The psychometric properties of the final model indicated the Malay language translated questionnaire is reliable and valid to investigate nurses’ perspective and involvement in end-of-life care.
RESUMO
RESUMEN El objetivo de este estudio fue adaptar y validar la escala del modelo de creencias de salud para el cáncer y autoexploración testicular (AT) en estudiantes universitarios en México y determinar las variables sociodemográficas, clínicas y del modelo de creencias que influyen en efectuar la AT. Se realizó el proceso de traducción y retraducción de la cual se obtuvieron 72 ítems, que fueron revisados por expertos y se eligieron 39 ítems, los cuales fueron aplicados en un grupo de 30 estudiantes para revisar la comprensión y el tiempo de aplicación; por último, esta versión se aplicó en 803 estudiantes de una universidad pública. Se obtuvo una escala de 38 ítems divididos en 6 factores congruentes con el modelo de creencias de salud: susceptibilidad (α = 0,77), seriedad (α = 0,82), beneficios (α = 0,80), barreras (α = 0,83), autoeficacia (α = 0,88) y motivación para la salud (α = 0,71) que explican el 44% de la varianza y presentan una consistencia interna de adecuada a buena. La variable que más influye en la realización de la autoexploración testicular fue la autoeficacia. La versión en español de la escala del modelo de creencias de salud para el cáncer y la autoexploración testicular obtuvo evidencias de validez y confiabilidad en esta muestra de estudiantes universitarios.
ABSTRACT The objective of this study was to adapt and validate the health belief model scale for testicular cancer and testicular self-examination (TSE) in university students in Mexico and to determine the sociodemographic, clinical, and health belief model variables that influence TSE performance. Translation and back translation were conducted, and 72 items were obtained and reviewed by experts, following which 39 items were selected and applied to a group of 30 students to assess comprehension and application time. Finally, this version was applied to 803 students at a public university. A scale consisting of 38 items was obtained, and the items were divided across six factors consistent with the health belief model: susceptibility (α = 0.77), seriousness (α = 0.82), benefits (α = 0.80), barriers (α = 0.83), self-efficacy (α = 0.88), and health motivation (α = 0.71). These factors explain 44% of the variance and show an internal consistency ranging from acceptable to good. The variable that most strongly influenced the performance of testicular self-examination was self-efficacy. The Spanish-language version of the health belief model scale for testicular cancer and testicular self-examination yielded evidence of validity and reliability in this sample of university students.

RESUMO
INTRODUCCIÓN: Tomando en consideración el concepto de Susceptibilidad al Castigo de la teoría de Sensibilidad al Refuerzo de Gray y la actividad lingüística-verbal interna propia del ser humano, se propone el concepto Susceptibilidad al Castigo Anticipado (SCA) debido a que no existe ningún instrumento para evaluarlo. El Objetivo: es diseñar y estudiar la bondad de los ítems, la estructura interna y la confiabilidad la Escala de Susceptibilidad al Castigo Anticipado (ESCA). Además, se presentan datos descriptivos de la ESCA. MÉTODO: Primero se elaboraron los ítems en función de la definición del concepto, después fueron valorados por expertos. En la fase piloto se administró la versión inicial de la ESCA a 240 personas adultas con las que se realizó la depuración y primer estudio de la consistencia a partir de un Análisis Factorial Exploratorio. Posteriormente, se realizó un Análisis Factorial Confirmatorio con la versión final en una muestra de 960 estudiantes universitarios, se corroboró la bondad de los ítems y se estudió la confiabilidad de la ESCA. RESULTADOS: Todos los ítems de la versión final resultaron adecuados. Se observó y corroboró en la fase final una estructura interna de tres factores (y uno de segundo orden). Los factores y la escala total mostraron adecuados valores de consistencia interna. CONCLUSIONES: La ESCA, a pesar de las limitaciones derivadas en gran parte al tratarse de un nuevo constructo, es un instrumento adecuado para evaluar la susceptibilidad al castigo anticipado en población universitaria de Michoacán (México).
INTRODUCTION: Taking into consideration the concept of Susceptibility to Punishment of Gray's Reinforcement Sensitivity theory and the internal linguistic-verbal activity of the human being, the concept of Susceptibility to Early Punishment (SEP) is proposed, because there is no instrument to evaluate it. The Objective: To Design and study the goodness of the items, the internal structure and the reliability of the Susceptibility to Early Punishment Scale (SEPS). In addition, descriptive data from SEPS are presented. METHOD: The items were first elaborated based on the definition of the concept, and were valued by experts. In the pilot phase, the initial version of the SEPS was administered to 240 adult people where information was filtered and the first study of consistency was done based on an Exploratory Factor Analysis. Subsequently, a Confirmatory Factor Analysis was performed with the final versión of the scale, in a sample of 960 university students. The goodness of the items was corroborated, and the reliability of the SEPS was studied. RESULTS: All the items of the final version were adequate; an internal structure of three factors (and one of the second order) was observed and corroborated in the final phase. The factors and the full scale revealed adequate internal consistency values. CONCLUSIONS: The SEPS, despite the limitations derived largely from being a new construct, is an adequate instrument to assess the susceptibility to early punishment in the university population of Michoacan (Mexico).
