摘要

Recent studies have reported differences in terms of high-risk drug using and sexual behaviour between younger and older injection drug users (IDUs), however, no studies have looked at the clustering pattern across IDUs using the theory of planned behaviour (TPB). The TPB is useful in the prediction of behavioural outcomes. This analysis examines the interplay of TPB components and needle sharing among a sample of IDUs from Montreal, Canada. The study includes 109 eligible IDUs, recruited via respondent driven sampling. Hierarchical cluster analysis was used to identify a typology of the respondents based on the responses to TPB measure. The results indicate that, among all of the measures, descriptive and injunctive norms, HIV/hepatitis C (HCV) status, and a measure of direct control were significantly different across the subtypes. Furthermore, it was possible to identify patterns in TPB measures across the subgroups. Specifically, the two TPB measures increased from the entrenched (Cluster 1), to the chronics (Cluster 4), to the initiators (Cluster 3), with the highest reported average within the survivor group (Cluster 2). Correspondingly, the proportion of the group reporting HIV/HCV status decreased in the opposite direction. Consequently drug use and HIV/HCV treatment and prevention programs need to concentrate intervention differently for each of these heterogeneous drug user populations.
