Evaluation and validation of a measure profiling needs and problems of psychiatric patients in the community: a
Background:
The Profile of Community Psychiatry Clients (PCPC) was developed in a Sydney-based sample of those with a mental illness as a 35-item measure of likely need for service recognition, review and possible assistance.
Methods:
This study has three principal objectives. Firstly, to test the utility of the PCPC measure in a very different region and culture. Secondly, to review the factor structure in an independent sample. Thirdly, to pursue the extent to which the PCPC might serve as a measure of likely need, by obtaining three differing reference viewpoints of need (i.e. clients, their carers, and case managers) and examining responses against PCPC scores. The PCPC was given to a sample of 333 Malaysian clients living in the community, together with two other measures of morbidity and disability. In addition, case managers, family members and clients were requested to directly rate the level of need for service assistance.
Results:
A principal components analysis favoured a six-factor solution, with PCPC factor scores and total scores intercorrelated with subscale and total scores on the Life Skills Profile (LSP) and Health of the Nation Outcome Scales (HoNOS). The correlation coefficients supported the concurrent validity of the derived PCPC scales. Family members rated the clients' needs as greater than did case managers who, in turn, rated severity of needs greater than the clients themselves. Most importantly, PCPC scores correlated more highly than did LSP and HoNOS scores with need estimates derived by all three rating groups, providing strong support for the PCPC meeting its objective as a measure of putative need. In addition, a refined 23-item version of the PCPC was derived, which retained the capacity of the PCPC to correlate strongly with needs estimates.
Conclusions:
This Malaysian study supports the use of the PCPC in a culture where service provision and family support for those with a mental illness vary considerably from Western regions, while its validation as a measure of need for service is supported.
