Co-occurring psychosocial distress and substance abuse in community clients: initial validity and reliability of self-report measures.

The current study examines the self-reports of 227 community support clients using a paper and pencil questionnaire that included the South Shore Problem Inventory-revised (a brief multidimensional psychosocial distress scale), a one-item index of self-rated substance abuse (SRSA), a quantity-frequency index for alcohol consumption (QFI), and a one-item index measuring the frequency of marijuana use. Results support the factor structure and internal consistency of the SSPI-r, and show significant correlations among the substance use indices. Implications for including brief mental health and substance abuse measures are discussed within the context of routine assessment and practice evaluation.
