OBJECTIVE
Structural analysis of the German translation of the "Client-Centered Rehabilitation Questionnaire" (CCRQ).

DESIGN
Cross-sectional multicenter study.

SETTING
Ten inpatient rehabilitation centers in Germany.

SUBJECTS
The CCRQ was completed by patients in the ten rehabilitation centers.

MAIN MEASURES
The psychometric analysis of the CCRQ was conducted using exploratory and confirmatory factor analysis.

RESULTS
The CCRQ was completed by 496 patients (average age: 59 years; 59.7% women). The CCRQ's 7-factor structure could not be confirmed. Factor analysis showed that the three latent constructs "decision-making/communication", "self-management/empowerment", and "psychosocial well-being" (60.73% variance explained) adequately represent patient-centeredness in medical rehabilitation assessed by the CCRQ. The scales possess good reliability (Cronbach's a = .83 to .87) and convergent criterion validity (r = 0.48 to 0.68). The three-factorial model exhibited good local and global data fit (RMSEA: 0.063, CFI 0.962, TLI 0.954) and proved to have a better data fit than concurring models (e.g. a model assuming an underlying factor).

CONCLUSIONS
A validated short form of the Client-Centered Rehabilitation Questionnaire, CCRQ-15, could be identified. Three scales based on 15 items allow assessing the key aspects of patient-centeredness in German medical rehabilitation.
