Turkish cultural adaptation and psychometric evaluation of the Client-Centered Rehabilitation Questionnaire

This study aimed to culturally adapt the Client-Centered Rehabilitation Questionnaire into Turkish (CCRQ-Tr) and evaluate its psychometric properties in outpatient rehabilitation.

This cross-sectional study followed international guidelines for translation and adaptation. Participants included 210 individuals who completed at least three weeks of rehabilitation. Psychometric evaluation included content validity, internal consistency, test-retest reliability, exploratory (EFA) and confirmatory factor analyses (CFA), and measurement error assessment.

The CCRQ-Tr demonstrated strong content validity (S-CVI/Ave = 0.977). Following EFA, two reverse-coded items (2 and 7) were removed due to insufficient factor loadings and low item-total correlations. The remaining items supported a seven-factor structure, explaining 50.25% of the variance. CFA showed excellent model fit (CFI = 0.992, RMSEA = 0.058). The scale demonstrated excellent internal consistency (α = 0.92) and test-retest reliability (ICC = 0.992). SEM and MDC values (4.21 and 11.64) supported the instrument's sensitivity to change.

The CCRQ-Tr is a valid and reliable tool for evaluating client-centered rehabilitation in Turkish outpatient settings. A comprehensive evaluation of patient experiences is made possible by assessing key elements such as communication and continuity of care. The integration of this tool into routine practice supports service quality improvements and promotes personalized care.
