Reliability and construct validity of the client-centred rehabilitation questionnaire.
OBJECTIVE
A key component in assessing the performance of rehabilitation services is the client's perspective. The purpose of this paper is to report on the development of a publicly available measure of client-centred rehabilitation (CCRQ) that can be used for discriminative and evaluative purposes.


METHODS
Mixed qualitatative and quantitative methods were used. Phase 1: Identification of seven domains of client-centred rehabilitation based on a literature review, focus groups with clients, and review by content experts. Phase 2: Item generation for the seven conceptually derived subscales and cognitive interviews with inpatient rehabilitation patients. Phase 3: Psychometric testing for internal reliability, test-retest reliability and discriminative construct validity using data from a mailed, self-administered survey to 1,568 patients discharged from two large inpatient rehabilitation facilities.


RESULTS
The seven conceptually derived subscales all have strong internal (0.72 - 0.87) and test-retest reliability (0.74 - 0.85). Discriminative construct validity is demonstrated by the ability of subscales to identify significant differences between programs within two rehabilitation facilities.


CONCLUSIONS
The results for the reliability and validity of this measure support its value for use in clinical and quality improvement work as well as research.
