DEVELOPMENT AND VALIDATION OF THE DRUG-TAKING CONFIDENCE QUESTIONNAIRE - A MEASURE OF COPING SELF-EFFICACY

The Drug-Taking Confidence Questionnaire (DTCQ; Annis & Martin, 1985) is a 50-item self-report questionnaire developed to assess situation-s pecific coping self-efficacy for use of a particular substance of abus e (e.g., cocaine, heroin, alcohol, cannabis, etc.). Results from explo ratory and confirmatory factor analyses of the DTCQ on 713 clients see king treatment at an addiction treatment facility provided strong evid ence for the situation-specificity of efficacy beliefs. An 8-factor fi rst-order model, based on the eight high-risk categories for relapse i dentified by G.A. Marlatt (Marlatt & Gordon, 1980) and a 3-factor seco nd-order model (i.e., negative situations, positive situations, and te mptation situations) provided the best fit to the data. All eight subs cales of the DTCQ were shown to have good reliability (alphas .79 to . 95). Extensive convergent and discriminant validity analyses for the D TCQ and its subscales in relation to ADS, DAST, OES, DRIE, SCQ, SCL-90 R BDI, HS, and SOCRATES substantiate that the DTCQ is a promising tool for further research and clinical application.
