Cross-cultural adaptation, reliability, and validity of the rehabilitation activities profile (RAP) in stroke patients.

Objective: The Rehabilitation Activities Profile (RAP) is an interview-based scale designed to assess both performance and self-perceived problem severity in activities of daily living (ADL). The aim of this study was to provide cultural adaptation of the RAP and to examine the reliability and validity of this adaptation individuals with stroke.

Methods: The translation and cross-cultural adaptation process followed Beaton's guidelines. A total of 81 individuals with stroke (36 female, 45 male) were included. Test-retest reliability was evaluated using the intra-class correlation coefficient (ICC), internal consistency was assessed using Cronbach's alpha, and construct validity was examined by analyzing the correlation between RAP scores and the Barthel Index (BI), a measure of ADL performance.

Results: Following the cross-cultural adaptation, minor modifications were made to enhance cultural relevance. Test-retest reliability was excellent, with ICC values of 0.976 for RAP disability and 0.986 for RAP self-perceived problem severity. Internal consistency was high, with Cronbach's alpha values of 0.953 for RAP disability and 0.911 for self-perceived problem severity. Construct validity analysis revealed a strong negative correlation between RAP scores and BI (r = -0.856, p < 0.001), supporting the validity of the scale.

Conclusion: This study provides preliminary evidence supporting the use of the Turkish RAP in clinical and research settings for comprehensive assessment of ADL-related disability and self-perceived problem severity in stroke patients.
