Adaptation and Validation of a Bangla Version of the Brief Resilient Coping Scale (BRCS) for Bangladeshi Older Adults

Abstract: Resilient coping, the ability to manage stress efficiently, is necessary to maintain well-being in old age. However, culturally validated tools to measure this construct among older adults in Bangladesh are lacking. Accordingly, this study assessed the reliability and validity of the Brief Resilience Coping Scale (BRCS) by examining its factor structure, measurement invariance, and item response characteristics. A cross-sectional survey was administered to a purposively selected sample of 681 Bangladeshi older adults aged 60–79 years. Split-sample CFA using the WLSMV estimator provided support for a stable invariant one-factor structure across subsamples, yielding strong factor loadings with overall excellent model fit. Due to the model’s low df, elevated RMSEA values were treated with caution. IRT analysis confirmed high item discrimination. Overall, the BRCS demonstrated strong internal consistency, test–retest reliability, measurement invariance, and content, construct, convergent, and divergent validity, thereby supporting its use as a measure of resilience among Bangladeshi older adults. However, the study's findings might not apply to population other than older adults in Bangladesh.
