Objective:To test whether mental health improvements observed in a nationally representative sample of 2466 HIV+ persons receiving care in the United States during the dissemination of combination antiretroviral therapy (ART) is a result of global optimism or directly related to treatment.
Analysis:Data were analyzed by means of a linear regression model of the change in psychiatric symptoms from baseline (January 1996-April 1997) to the first followup interview approximately 8 months later as a function of changes in CD4+ counts, opportunistic infection treatments, and HIV physical symptoms in the overall sample and separately in participants who maintained ART, initiated ART, never received ART, or transitioned to a less recommended regimen during the study period.
Results:The reduction in psychiatric symptoms was comparable across all treatment groups (p > .05), suggesting a global effect. In patients who initiated or maintained ART, fewer psychiatric symptoms were significantly related to higher CD4+ and fewer opportunistic infection treatments and HIV symptoms, however, suggesting a treatment effect.
Conclusion:ART appears to be responsible for both a treatment-specific and global improvement in the mental health of HIV+ patients, possibly through the promise of extended survival and a better quality of life.
