The development and evaluation of the Harm Reduction Self-Efficacy Questionnaire

Psychol Addict Behav. 2008 Mar;22(1):36-46. doi: 10.1037/0893-164X.22.1.36.


The authors recruited 99 injection drug users to assess the psychometric properties of a new self-report questionnaire--the Harm Reduction Self-Efficacy Questionnaire (HRSEQ)--designed to measure injection drug users' confidence to employ 15 specific health-preserving coping skills in different types of high-risk situations (experiencing withdrawal, feeling depressed, and feeling social pressure to use drugs unsafely). Scores for each high-risk situation had good internal consistency (alphas = .89 -.92) and good 1-week test-retest reliability (rs = .70 -.85). Comparison with measures of drug-related problems, use of coping skills, and health self-efficacy supported both construct and discriminant validity of the HRSEQ. Exploratory factor analyses revealed 3 major themes (cleanliness precautions, overdose precautions, and safer injection practices) that summarized most, but not all, of the 15 items. Mean differences among the 3 situations suggest that harm reduction self-efficacy should be assessed in the context of specific high-risk situations.
