Development of self-efficacy and expectancy measures for benzodiazepines
Parr JM et al. - The scales provide reliable measures for assessing benzodiazepine self-efficacy and expectancies. Future research will examine the utility of the scales in prospective prediction of benzodiazepine cessation. Methods- Internal structure of the questionnaires was established by principal component analysis (PCA) in a sample of 155 respondents, and verified by confirmatory factor analyses (CFA) in a second independent sample (n = 139) using structural equation modeling.
Results- The PCA of the BRSEQ resulted in a 16-item, 4-factor scale, and the BEQ formed an 18-item, 2-factor scale.
- Both scales were internally reliable.
- Lower self-efficacy and higher expectancy were moderately associated with higher scores on the SDS-B.
