Translation, cross-cultural adaptation, and validation of the heart disease fact questionnaire among the Brazilian population

SUMMARY OBJECTIVE: This study aimed to translate, cross-culturally adapt, and validate the Heart Disease Fact Questionnaire into Brazilian Portuguese. METHODS: The Brazilian version of the Heart Disease Fact Questionnaire was developed through the processes of translation, back-translation, review committee, and pre-test. Test-retest reliability was measured using the intraclass correlation coefficient and the kappa coefficient. Internal consistency was measured using Cronbach's alpha. For construct validity, the total Heart Disease Fact Questionnaire score was correlated with the Diabetes Knowledge Scale and the Diabetes Attitudes Questionnaire. Ceiling and floor effects were also evaluated in this study. RESULTS: For construct validity and floor and ceiling effect measurements, a total of 100 participants were selected. Reliability was measured using a sub-sample of 30 participants from the total sample. We identified adequate values of reliability (kappa between 0.22 and 1.00 and ICC=0.75) and internal consistency (Cronbach's alpha=0.79). We observed adequate correlations of the Heart Disease Fact Questionnaire score with Diabetes Knowledge Scale (r=0.348) and Diabetes Attitudes Questionnaire (r=0.136). No ceiling or floor effects found. CONCLUSION: Brazilian Portuguese version of the Heart Disease Fact Questionnaire has adequate psychometric properties according to the best scientific recommendations.

Evaluation of key survey components of bio-behavioral surveillance among HIV high-risk subpopulation in Western India

Background: High-quality data are of prime importance in any health survey because survey data are considered as a gold standard for nationally representative data. The quality of data collection largely depends on the design of the questionnaire, training, and skills of the interviewer. Objectives: In the present study, we tried to evaluate three key components, such as questionnaire design, human resource and training of the field staff for Integrated Biological and Behavioural Surveillance carried out among the HIV high-risk subpopulation. Methods: A mixed-methods approach was used. Qualitative and quantitative data collection was carried out in the year 2015 with cross-sectional survey design in western states of India. The in-depth interviews of 10 stakeholders, structured interviews of the survey respondents (n = 560), and field investigators (n = 71) were conducted. Data triangulation was used to find out the concurrence of the qualitative and quantitative data. Results: Comprehensive and standardized survey questionnaire, structured training agenda, and strategic preparation for recruiting human resources were the overall strengths of the survey. However, during the implementation of the survey, there were some difficulties reported in data collection process. Overall, the respondents and investigators felt that the questionnaire was long and exhaustive. Difficulties were faced while collecting data on sexual history. The field staffs were not adequately experienced to work with sensitive population. Conclusions: In order to have accurate, reliable data, especially on sexual behavior; emphasis should be given on simple questionnaire with the use of community-friendly language, skilled and experienced interviewers for data collection, and extensive field training.

Reproducibilidad y sensibilidad del cuestionario Impacto del peso en la calidad de vida en mexicanos obesos / Reproducibility and sensitivity of the impact of weight on quality of life questionnaire among obese Mexicans

Objetivo: Determinar si el cuestionario “Impacto del peso en la calidad de vida” (IWQOL) es reproducible y sensible para identificar diferencias entre las clases de obesidad establecidas por la Organización Mundial de la Salud. Métodos: El IWQOL fue traducido al castellano de acuerdo a la usanza del lenguaje en México pero manteniendo un vocabulario amplio para América Latina. Investigamos la reproducibilidad del cuestionario por el método de prueba-reprueba (n=82, IMC=37.8±8.4), la sensibilidad para identificar diferencias entre los grados de la obesidad (n=105, IMC=35.1±9.5) y la sensibilidad para detectar diferencias después de recibir algún tratamiento para la pérdida del peso (n=40, IMC=39.2±7). Resultados: El IWQOL mostró buena reproducibilidad y sensibilidad para identificar diferencias entre grupos de obesos y cambios luego de tratamiento. Todos los dominios fueron reproducibles (criterio a priori: la diferencia entre prueba re-prueba no debía ser mayor de 5 puntos porcentuales) y tuvieron alta validez interna (coeficiente alfa de Cronbach>0.92 para todos los dominios). El IWQOL detectó diferencias entre los grupos divididos por la severidad de la obesidad, siendo los más afectados aquellos con IMC>45. Los sujetos sometidos a tratamiento perdieron 6.4 kg (IC95%=4.6-8.2) durante un periodo de 2.70±1 meses e incrementaron la calificación en todos los dominios, excepto el correspondiente a “trabajo”. Conclusiones: El cuestionario IWQOL es una herramienta confiable y sensible que se puede utilizar para la investigación de la calidad de vida en mexicanos y probablemente en la mayoría de las poblaciones latinoamericanas. Nuestro estudio es el primero envalidar el IWQOL en México.

OBJECTIVE: Determine if the Spanish version of the IWQOL (Impact of Weight on Quality of Life) questionnaire is reproducible and sensitive to detect differences among WHO's classification of obesity. METHODS: The IWQOL was translated into Spanish and adapted to the Mexican context while maintaining a wide comprehensive vocabulary applicable to Latin American countries. We measured reproducibility using a test-retest method (n=82, BMI 37.8+/-8.4), sensitivity to detect differences between types of obesity (n=105, BMI 35.1+/-9.5), and sensitivity to detect differences after treatment for weight loss within groups (n=40, BMI 39.2+/-7). RESULTS: The IWQOL questionnaire was reliable and sensitive enough to detect differences among and within groups. All domains were highly reproducible (scores differed by less than 2 points) and had high internal validity (Cronbach alpha coefficient >0.92 for all scales). The IWQOL detected differences between groups stratfied by severity of obesity, the lowest score was for BMI >45. Subjects who underwent weight loss treatment and lost 6.4 kg (95% CI 4.6, 8.2) during a period of 2.70+/-1 month had an improvement in all scales except for the [quot ]Work[quot ] domain. CONCLUSIONS: The IWQOL questionnaire is a reliable and sensitive tool that can be used for research purposes in Mexico and the Latin America region. Our study validates the use of IWQOL among Mexican subjects.
