Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Investigators will conduct a two-arm, comparative effectiveness randomized controlled trial of two culturally adapted, empirically based programs (EBP) - Narrative Exposure Therapy (NET) vs. Motivational Interviewing with Skills Training (MIST) in terms of lowering HIV sexual-risk behaviors (HSB) for American Indian / Alaska Native (AIAN) men and women. NET addresses Posttraumatic Stress Disorder (PTSD) as a pathway to preventing substance use disorders (SUD) and HSB whereas MIST addresses substance misuse as a way of preventing SUD and HSB.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Recruitment Participants will be recruited from tribal health and wellness service agencies and counseling centers on the Reservation as well as through advertising in the community. Investigators will post flyers in public spaces like coffee shops, the library, the cultural center, and community centers. We will also send the flyer through the tribal listserv; post it on Facebook, and the local newspaper. Investigators will provide brief oral presentations at the local health centers to orient providers of the project and provide contact information and flyers. Providers and potential participants who are interested may contact the study coordinator for more information

Screening

* Participants are screened in person or over the phone using a screening script.
* Participants who screen out will be given a community resource list either by mail, email, or in person.
* If a person is eligible but declines to participate, they will be given a one item exit question regarding general reason for non-participation.

Consent and Baseline Assessment After completing the screener, the participant will be scheduled for an in-person consenting / baseline assessment appointment. Study staff will review the consent form with the participant. Once participant has consented, study staff will gather all relevant contact information. Next, study staff will set up the computer for the participant to complete the Audio Computer Assisted Self-interview (ACASI) survey, which will take approximately 30 minutes. While the participant is completing the survey, local study staff will call the Research Coordinator (RC) to confirm the consent has been obtained and to determine randomization. The RC will let the local study staff know which counselor the person should be scheduled with for the 1st counseling appointment. The counselor will inform which therapy the participant was assigned to at their first counseling session. Once participant completes the computer survey, study staff will schedule their first counseling appointment to take place within a week of the baseline appointment.

Assessments The assessments will be conducted via Audio-Computer Assisted Self-Interviews (ACASI) programmed into study computers. Participants will complete 4 surveys: baseline, immediately after completing counseling, a three-month follow up and a six-month follow up.

Counseling sessions Participants will be randomly assigned to either NET or MIST. To ensure the equivalence of groups and to reduce opportunities for selection bias we will stratify the randomization by gender (male vs. female) and age groups (\<30 vs. \>=30) and perform randomization in blocks with varying size (4/6/8). Participants will begin their six 90 to 120 minute sessions in within a week of completing the Baseline assessment. Each counseling session is audio recorded in order for investigators to test for fidelity and adherence to the culturally adapted therapy.
