PRIMARY OBJECTIVE: This study compared the psychometric properties of two community integration measures used with people with acquired brain injury (ABI) in the community. RESEARCH DESIGN: Questionnaires were mailed-out to people with ABI and nominated proxies. METHODS AND PROCEDURES: Responses were obtained from 96 people with ABI and 121 proxies on the Community Integration Questionnaire (CIQ) and the Sydney Psychosocial Reintegration Scale (SPRS). MAIN OUTCOMES AND RESULTS: Matched client-proxy scores were not significantly different. The SPRS had greater internal consistency and more normal distributions than the CIQ. Correlations between the three pairs of theoretically parallel sub-scales were modest (0.41-0.60). Multi-dimensional scaling did not support the theoretical structure of the sub-scales, but found two dimensions underpinning the measurement of community integration. CONCLUSIONS: Mail-out administration is associated with poor completion rates. The SPRS has sound psychometric properties when compared to the CIQ. Further research investigating the theoretical structure of community integration in ABI is recommended.
