What this trial studies

This trial aims to optimize HIV prevention strategies for people who inject drugs (PWID) who are newly prescribed medication for opioid use disorder and Pre-Exposure Prophylaxis (PrEP). A total of 256 participants will be randomized into one of 16 intervention conditions that combine core behavioral components with additional strategies focused on enhancing attention, executive functioning, memory, and information processing. The goal is to improve participants' ability to process and utilize HIV prevention information, ultimately leading to better motivation, behavioral skills, and safer behaviors. The study employs a multiphase optimization strategy to assess the effectiveness of these combined interventions.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older who are newly prescribed medication for opioid use disorder, have mild cognitive impairment, and have recently initiated PrEP.

Not a fit: Patients who are unable to provide consent, actively suicidal, or have severe cognitive impairments may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could significantly enhance HIV prevention efforts among PWID, leading to reduced transmission rates and improved health outcomes.

How similar studies have performed: Other studies have shown promise in using behavioral interventions to improve health outcomes in similar populations, suggesting that this approach may be effective.
