Resumen


Abstract:
Objectives: To perform an analysis of the psychometric properties of the Brazilian Portuguese version of the COMMUNITY ATTITUDES TOWARDS THE MENTALLY ILL (CAMI-BR), a 40-item scale divided into four sub-scales. Methods: The study was conducted in a non-probability sample of 230 households located close to therapeutic residences in the west area of Rio de Janeiro. Reliability was assessed by test-retest and the Principal Component Analysis (PCA) was used to test the internal structure of the questionnaire. Results: Most participants were women, married, with children aged 18 years or over. The overall score was 27.72 (SD = 3.31), showing attitudes ranging from neutral to positive stereotypes. The scale showed a high internal consistency (? = 0.842), consistent with other international studies. In the factor analysis, the sample was adequate (KMO = 0.800). The strength of the correlations among subscales and the factors of factor analysis were highly satisfactory. The version in Brazilian Portuguese suggests a better distinction among sub-scales through the lower correlation among them (between 0.336 and 0.441) as compared to higher values (between 0.630 and 0.770) found in the original scale. The
community mental health ideology sub-scale showed a strong relation to factor 1 (? = 0.910). Benevolence had a strong relationship with factor 2 (? = 0.847); Authoritarianism and Social Restrictiveness had the highest correlation with factor 3 (? = 0.631 and 0.577 respectively). Conclusions: The scale psychometric properties were maintained after adjustment. Having registered a lower correlation between the scales the factor analysis further suggests that the Brazilian Portuguese version conveys more clearly the differences between the sub-scales.


Resumen:
Objetivos: Realizar un análisis de las propiedades psicométricas de la versión en portugués de las actitudes de la comunidad hacia los enfermos mentales (CAMI-BR), una escala de 40 ítems dividido en cuatro sub-escalas. Métodos: El estudio se realizó en una muestra no probabilística de 230 hogares ubicados cerca de las residencias terapéuticas en la zona oeste de Río de Janeiro. La fiabilidad se evaluó mediante test-retest y el Análisis de Componentes Principales (PCA) se utilizó para probar la estructura interna del cuestionario. Resultados: La mayoría de los participantes eran mujeres, casado, con hijos de 18 años o más. La puntuación global fue de 27,72 (SD = 3,31), mostrando actitudes que van desde neutral a los estereotipos positivos. La escala mostró una alta consistencia interna (? = 0,842), en consonancia con otros estudios internacionales. En el análisis factorial, la muestra era adecuado (KMO
= 0,800). La fuerza de las correlaciones entre las subescalas y los factores del análisis factorial fueron altamente satisfactorios. La versión en portugués de Brasil sugiere una mejor distinción entre las subescalas a través de la menor correlación entre ellas (entre 0.336 y 0,441) en comparación con los valores más altos (entre 0.630 y 0.770) que se encuentra en la escala original. La sub-escala de ideología de la salud mental de la comunidad mostró una fuerte relación al factor 1 (? = 0,910). La benevolencia tenía una fuerte relación con el factor 2 (? = 0,847); El autoritarismo y restricción del Social tuvieron la mayor correlación con el factor 3 (? = 0,631 y 0,577, respectivamente). Conclusiones: Las propiedades psicométricas escala se mantuvieron después del ajuste. Después de haber registrado una menor correlación entre las escalas del análisis factorial sugiere además que la versión en portugués brasileño transmite más claramente las diferencias entre las sub-escalas.
