title: Reliability of drug users' self-reported HIV risk behaviors using a brief, 11-item scale.
abstract: This study evaluated the reliability of self-reported HIV risk behaviors in 84 substance misusers. The 11-item HIV Risk Behavior Scale was, used to evaluate lifetime, past month, and past week risk behaviors. Cronbach's alpha ranged from .75 to .80 for the three versions. Test-retest reliability for the lifetime version was excellent, with correlations of .90. In addition, 44 clients completed the weekly version once a week for four weeks, as well as the monthly version at the end of the same month. Reliability of responses collected weekly and monthly was good (r=.67, p < .001). Principal component analysis of the items confirmed that the scale measures two distinct HIV risk factors: one related to injecting behaviors and the other to sexual behaviors. These data suggest that the HRBS has satisfactory psychometric properties for measuring lifetime as well as recent HIV risk behaviors in substance misusers. Due to its brevity, this instrument may be a useful clinical and research tool.
