HIV Risk, Substance Use, and Personality Characteristics among Adults with History of Serious Mental Illness.

The present study examined the relationship between characteristics associated with personality disorders, substance use, and HIV risk among adults with a history of serious mental illness. Participants included 103 adults with antisocial or borderline personality disorder, serious mental illness, and recent HIV risk behavior. The sample was predominately male (64%), diverse (42% African American and 13% Hispanic), and homeless/marginally housed (76%). In order to examine the relationship between personality characteristics and risk we constructed a risk index comprising key symptoms of antisocial and borderline personality disorders, namely; impulsivity, affective instability, and disregard for safety of self/others. Contrary to our primary hypotheses, risk index scores did not predict HIV risk behavior and substance abuse did not mediate this risk. Exploratory analyses did reveal that women engaged in significantly more risk behaviors than their male counterparts and that risk scores were a significant predictor of total sex acts for women but not men. In addition, increased emotional dysregulation was a significant predictor of condomless sex acts for women but not men. Finally, recent alcohol use and increased impulsivity was associated with more condomless oral sex for men and women. These results suggest the relationship among serious mental illness, personality disorder, substance abuse, and gender is complex and merits further study.

Major depression in patients with HIV/AIDS and substance abuse.

Previous research has been inconsistent in documenting a strong relationship between depression and HIV/AIDS, although a recent meta-analysis of studies examining this issue indicates that rates of depression are modestly higher for this population. For the current study, conducted from 2001-2004, we sought to examine rates and types of depressive symptoms in a cohort of patients receiving HIV care at two urban medical centers. These patients were participants in an intervention study examining adherence and mental health in persons triply diagnosed with psychiatric disorders, substance use disorders, and HIV/AIDS. Nearly three quarters of these participants were people of color, two thirds described their sexual orientation as heterosexual, and the vast majority were unemployed. We sought to examine the relationship of depression to patients' adherence to antiretroviral medication regimens (highly active antiretroviral therapy [HAART]). Results obtained from structured clinical interviews and self-report questionnaires indicated that study participants experienced high rates of depressive symptoms, and that 72.9% of participants met criteria for major depressive disorder (MDD). The results of this study offer a detailed view of the incidence and nature of MDDs and depressive symptoms for an urban sample of substance-abusing adults with HIV/AIDS. Given the degree to which depressive symptoms and MDD appear to be prevalent for this group, as well as the observation that these symptoms are amenable to treatment, future research should focus on identifying helpful strategies and interventions for treating these symptoms, effective ways of providing linkages to care, and ways in which standardized assessment and treatment protocols might be adapted to better suit this population.
