title: Development and initial validation of an instrument to measure perceived coercion to enter treatment for substance abuse.
abstract: The present study involved 3 phases that led to the development and initial validation of the Perceived Coercion Questionnaire (PCQ), a scale that researchers use to measure perceptions of coercion of drug and alcohol users to enter drug and alcohol treatment. In Phase 1, the authors used focus groups to generate 48 pilot items. In Phase 2, the items were administered to a sample of 158 drug and alcohol users who were in residential treatment within a therapeutic community setting. Item and exploratory factor analyses reduced the number of items to 32, which represented 6 homogeneous and internally reliable subscales. In Phase 3, the PCQ was administered to a second sample of 362 drug and alcohol users. Confirmatory factor analysis led to a final scale of 30 items across 6 subscales that demonstrated sound consistency and validity. Implications for research and practice are highlighted.
