Efficacy expectations among alcohol-dependent patients--a Swedish version of the Situational Confidence Questionnaire.

The Situational Confidence Questionnaire (SCQ) developed by Annis (1986 A relapse prevention model for treatment of alcoholics. In Treating Addictive Behaviors. Processes of Change, Miller W. R. and Heather, N. eds, pp. 407-435. Plenum Press, New York) is an important assessment instrument for use in the treatment of alcoholism and particularly in relapse prevention. The SCQ was translated into Swedish and tested on 91 alcohol-dependent patients. A principal component analysis of the item responses resulted in a shortened 35-item version of the SCQ with satisfactory test-retest reliability, internal consistency and scale specificity. Instead of eight relapse situation categories the analysis resulted in four categories with lower intercorrelations than in the original SCQ. The components were: (1) unpleasant emotions; (2) social pressure; (3) testing personal control; and (4) positive emotional states. In a one-way ANOVA only the Social Pressure scale had a significant relationship with severity of alcohol problems.
