“…El tamaño de la muestra se determinó con la fórmula de Gabaldón (1980) para poblaciones finitas, y el resultado fue un total de 385 participantes, de un universo de 8.223 estudiantes de educación media y superior en el norte de Jalisco (Secretaría de Educación Jalisco, 2017). Posteriormente se duplicó la muestra para evitar el error Tipo I para lograr que los análisis factoriales fueran estables y generalizables (Koran, 2016;Morata-Ramírez, Holgado-Tello, Barbero-García, y Méndez, 2015).…”

Confirmatory factor analysis and psychometric properties of the Beck Hopelessness Scale in students in contexts of poverty in Mexico. Hopelessness predicts depression and suicide. In the world, suicide is the second cause of death in people between 15 and 29 years, and depression is the main cause of disability. The internal factorial structure, reliability and construct validity of the Hopelessness Scale were analyzed in upper secondary and higher education students in contexts of poverty in Mexico. 771 participants were evaluated. Reliability was examined with the coefficient omega, and validity with confirmatory factor analysis with the weighted least square mean and variance adjusted method. The value of omega was .89. The confirmatory factor analysis revealed an SRMR = .07, CFI = .95, TLI = .94, RMSEA = .05. The scale is valid and reliable for students in contexts of poverty in Mexico.Keywords: Reliability; validity; students; Beck Hopelessness Scale.Resumen: La desesperanza predice la depresión y el suicidio. En el mundo, el suicidio es la segunda causa de muerte en personas de 15 a 29 años, y la depresión es la principal causa de incapacidad. Se analizo la estructura factorial interna, fiabilidad y validez de constructo de la Escala de Desesperanza de Beck en estudiantes de educación media superior y superior en contextos de pobreza en México. 771 participantes fueron evaluados. Se examinó la fiabilidad con el coeficiente omega, y la validez con el análisis factorial confirmatorio con el método weighted least square mean and variance adjusted. El valor de omega fue de .89. El análisis factorial confirmatorio arrojó un SRMR = .07, CFI = .95, TLI = .94, RMSEA = .05. La escala es válida y fiable para los estudiantes en contextos de pobreza en México.Palabras clave: Fiabilidad; validez; estudiantes; Escala de Desesperanza de Beck.

Background: The European Health Literacy Survey Questionnaire (HLS-EU-Q47) is becoming a widely used tool to measure health literacy (HL), including in Malaysia. There are efforts to reduce the 47-item scale to parsimonious short item scales that still reflect the assumptions and requirements of the conceptual model. This study used confirmatory factor analysis to reduce the 47-item scale to a short scale that can offer a feasible HL screening tool with sufficient psychometric properties. Methods: A cross-sectional survey was conducted on the Malaysian population based on ethnic distribution to ensure that the short version instrument reflects the country's varied ethnicities. The survey was administered by well-trained interviewers working for the Ministry of Health Malaysia. A total of 866 responses were obtained. Data was analysed using multi-factorial confirmatory factor analysis (CFA) with categorical variables. Results: The analysis resulted in a satisfactory 18-item model. There were high correlations among the 18 items. The internal consistency reliability was robust, with no floor/ceiling effects. These results represented equivalence and consistency among the responses to items, suggesting that these items were homogenous in measuring Malaysian health literacy. The strong convergent and discriminant validity of the model makes the proposed 18 items a suitable short version of the health literacy instrument for Malaysia. Conclusions: The researchers propose the 18-item instrument to be named HLS-M-Q18. This short version instrument may be used in measuring health literacy in Malaysia as it achieved robust reliability, structural validity and construct validity that fulfilled goodness-of-fit criteria.
