Psychometric Properties of the Arabic Version of the Belief into Action Scale

Safa Alakhdhair, Ph.D. Student, Indiana State University

OBJECTIVE: The Belief into Action Scale (BIAC) is comprehensive measure of religious involvement 
intended for monotheistic religious traditions. We examine the psychometric properties of an Arabic version of 
the BIAC for administration in Muslim populations. 
METHODS: A convenience sample of Arabic-speaking Muslims completed an online survey including 
the 10-item Arabic BIAC and other psychosocial and religious measures. Psychometric properties of the BIAC 
were examined, including internal reliability, test-retest reliability, convergent validity, discriminant validity and 
factor analytic validity. 
RESULTS: 211 participants completed the BIAC (100% Muslim, average age 31.9, 54% male). The average 
score was 47.6 (SD=15.7). Cronbach alpha was 0.80 (95% CI 0.76-0.84) and intra-class correlation coefficient 
between two administrations (n=30) was 0.88 (95% CI 0.77-0.94). Convergent validity was demonstrated by 
high correlations between the BIAC and existing religiosity scales (r=0.52-0.58); divergent validity by weak 
correlations with psychosocial measures (0.09-0.21); construct validity by high correlations between individual 
items and total scale score (r’s 0.53-0.72); factor analytic validity by a single factor that explained 81.1% of the 
scale’s variance; and predictive validity by small correlations with psychosocial outcomes in expected 
directions. 
CONCLUSION: The Arabic BIAC is a reliable and valid scale for comprehensively assessing religious 
involvement in Muslim Arabic-speaking populations.  T
