Telephone IPT Intervention for HIV-Infected Rural Persons

Compared to their urban counterparts, HIV-rural persons are more likely to be diagnosed with depression, less likely to seek assistance from mental health professionals, and appear to have shorter periods of survival. This application responds to PA-07-103 ("Research on Rural Mental Health and Drug Abuse Disorders") and the PA's stated need for research that will "Study whether individuals with various mental disorders can be treated effectively via telemedicine." A pilot RCT recently completed by our team showed that a 6-session telephone-delivered, interpersonal psychotherapy (IPT) intervention reduced depressive symptoms in 79 HIV- infected rural persons (Ransom, Heckman, et al., 2008, Psychiatric Services). This follow-up RCT will enroll 180 persons living with HIV/AIDS in rural counties in the United States who are diagnosed with depression via telephone interviews. Participants will complete self-administered surveys at pre-intervention, post- intervention, and 4- and 8-month follow-up that assess depressive symptoms (the primary outcome measure), interpersonal problems, social support, and ART adherence. Participants will also provide weekly data (for 41 weeks) via interactive voice response (IVR) systems that assess depressive symptoms (41 weeks) and therapeutic alliance (9 weeks). Ninety (n=90) participants will be randomly assigned to a 9-session, one-on- one, telephone-delivered, IPT intervention and 90 will be assigned to a usual care comparison group. Linear mixed models (LMM) will test if IPT participants report greater reductions in depressive symptoms compared to usual care controls. Analyses of reliable change will test if a greater proportion of IPT participants report clinically-significant reductions in depressive symptoms compared to usual care controls. Using weekly data collected via IVR systems, time series analyses will test if IPT participants report greater decreases in depressive symptoms over a 41-week follow-up period compared to usual care control. Mixed models analyses will assess the importance of therapeutic alliance in telephone-delivered IPT. Public Health Significance: This study will test if nine sessions of telephone-administered interpersonal psychotherapy can reduce depressive symptoms in HIV-infected rural persons, a group that is increasing in size and that experiences great difficulty accessing mental health support services.
