RESUMEN
Various approaches have been developed to comprehensively assess multiple dimensions of religiosity. The Belief into Action (BIAC) Scale was developed for this purpose and to evaluate the degree of translation of personal beliefs into real-life actions. The goal of the present study was to assess the validity and reliability of the Moroccan Arabic version of the Muslim BIAC, designed to assess the religiosity of Muslims. This study was conducted in two stages. First, the original version of Muslim BIAC was translated from English to Arabic using a standard forward-backward translation procedure. Second, the Moroccan Arabic version of the Muslim BIAC was administered to a sample of 132 students at Ibn Zohr University, Agadir, Morocco (mean age 22.2 years). The average score on the BIAC was 46.1 (SD = 17.2). The Cronbach's alpha for internal reliability was 0.81, with alphas for removed items ranging from 0.77 to 0.82. Test-retest reliability by intraclass correlation coefficient (ICC) was 0.87 (95% CI = 0.83-0.91). Discriminant validity indicated relatively weak correlations with depressive symptoms (r = - 0.06) and perceived stress (r = 0.08). The Moroccan Arabic version of the Muslim BIAC is a reliable and valid measure of religious involvement that can be used to assess the relationship between religiosity and health in Moroccan Arabic populations.
