Psychometric Rigor of the Brief Religious Coping Measure (RCOPE) in Persian-Speaking Older Adults

Religious coping to deal with negative life events has gained considerable attention in recent years. This study was conducted to investigate psychometric properties of the Persian version of Brief RCOPE measure (RCOPE-P). The RCOPE-P was devised using a standard translation/back-translation procedure and its internal consistency and test-retest reliability were estimated using Cronbach's alpha and intraclass correlation coefficients. The instrument's factor structure was appraised in a sample population of 400 older adults with chronic diseases. Positive and negative subscales of the RCOPE-P indicated acceptable internal consistency (0.74, 0.80) and test-retest reliability (0.89, 0.91). Confirmatory factor analysis confirmed fitness of the original 2-factor model (root mean square error of approximation (RMSEA) = 0.046, CFI = 0.967, Tucker-Lewis index (TLI) = 0.953, and standardized root mean square residual (SRMR) = 0.052) to the data obtained from the study. The findings endorsed applicability of the RCOPE-P for the Persian-speaking older adults but its adaptability in other Persian-speaking population subgroups must be further examined.
