A suggested revision of the Community Oriented Program Environmental Scale (COPES) for measuring the psychosocial environment of supported housing facilities for persons with psychiatric disabilities.

The aim of the present study is to address issues of construct validity and reliability of a revised short version of the COPES instrument to measure the psychosocial environment of supported housing facilities for persons with psychiatric disabilities. The results revealed that the division into subscales is not sufficiently reliable for use in measuring the psychosocial environment, although the three higher order dimensions can possibly be used for the descriptive and comparative purposes. A factor analysis based on the revised short version generated new factor solutions, differing from the COPES subscales, but with sufficient psychometric properties.
