Cluster analysis of HIV intervention outcomes among substance : Abusing women.
The study described here presents an innovative approach to analyzing intervention outcomes among women substance abusers participating in a national HIV prevention research study funded by the National Institute on Drug Abuse.
We used cluster analysis to divide the women in our sample (N=557) into four distinct subgroups predominantly characterized by differences in drug use, injecting risk, sexual behaviors, and drug and sexual risk combined.
The four subgroups resulting from this process were primary crack-using women, primary needle-using women, high-frequency needle-using women, and women with multiple drug and sex risk behaviors.
Our analysis focuses on changes in self-reported risk behaviors from baseline to 6-month follow-up.
In general, the results clearly indicate that the women are heterogeneous ; that is, the subgroups exhibit varying patterns of drug use, injecting risk, sexual behavior, and HIV seropositivity.
Significant outcomes were found in many areas, indicating positive changes in risk behaviors.
The two smaller subgroups of women-high-frequency needle users and those in the multiple-risk behavior subgroup-reported the highest rate of high-risk behaviors and seropositivity but also showed the greatest change at follow-up.
A particularly important finding resulting from our analytical approach is that well over half the women in our sample were primary crack users (n=313). (...)
