Cognitive Processing Intervention for Trauma, HIV/STI Risks, and Substance Use Among Native Women

Summary

Many American Indian (AI) women never receive services for serious mental health problems resulting from traumatic events, violence exposure and maltreatment. AI women suffer higher lifetime rates of Post-traumatic Stress Disorder (PTSD) (20-23%), that often co-occur with excessive drinking and risky sexual behaviors. These factors magnify risk for human immunodeficiency virus and sexually transmitted disease (HIV/STI). In full development with tribal partners, this application, proposes a 3-year project to culturally adapt and pilot an empirically supported trauma-focused treatment, Cognitive Processing Therapy (CPT) for PTSD, substance use and HIV/STI sexual risk behavior among 50 AI women. Additionally, the investigators will assess the feasibility, acceptability and treatment fidelity of delivering CPT via AI community health workers in a resource-limited tribal reservation. This project brings a culturally responsive intervention to an understudied and highly vulnerable population. Its significance lies in its potential to advance science in the area of PTSD, substance use treatment and HIV/STI prevention among AI women. Study data would benefit tribal and rural communities and the mental health field. Finally, it is geared toward developing the research infrastructure and mental health treatment capacity serving AI women living in rural settings, a group at risk for an expanding HIV/AIDS epidemic. If successful, findings from this pilot will provide evidence for a larger effectiveness trial.

The AIMS are AIM I. Adapt the evidence-based CPT intervention in full collaboration with tribal partners. This will be done in accordance with the CDC's Map of Adaptation Process and involves formative research with tribal leaders, potential consumers, providers, and health care administrators using qualitative methodology.

AIM 2. Assess this intervention delivered by Native American community health workers for feasibility and acceptability in a resource-limited rural reservation setting.

AIM 3. Conduct a two-group, single-site waitlist randomized controlled pilot trial of a 12-session, 6-week CPT intervention among 56 (6 pilot) sexually active and substance using AI women with PTSD or sub-threshold PTSD. Determine preliminary efficacy and estimate an effect size in terms of three primary outcomes: (a) PTSD symptomatology; (b) substance use; (c) high risk sexual behavior.

Interventions

BEHAVIORAL

Cognitive Processing Therapy-Cognitive

Cognitive Processing Therapy-Cognitive (CPT-C) uses education about trauma reactions, emotional processing, and cognitive strategies to reduce trauma-related cognitive distortions. CPT is a manualised 12 session cognitive behavioral treatment for PTSD which offers an alternative to purely exposure based interventions. CPT has a smaller exposure component than imaginal exposure therapy and is therefore potentially more acceptable to clients or practitioners seeking alternatives to purely exposure focused treatments. CPT-C omits the written trauma account, and includes more practice of cognitive techniques during the sessions. The treatment was developed for twice weekly sessions over 6 weeks. It also directly targets associated problems such as depression, guilt and anger.
