Implementing a multisite efficacy trial to facilitate maternal disclosure to children: the TRACK HIV Disclosure...

HIV remains prevalent, stigmatized, and requires parents to decide whether and how to disclose to their serostatus to their children. Teaching Raising And Communicating with Kids (TRACK), an intervention to support maternal disclosure of HIV status to children, demonstrated efficacy through a pilot and a full-scale multisite trial. In response to the limited availability of best practices for conducting multisite research and recognizing the importance of identification of key intervention components, the current manuscript presents the traditional elements of an implementation paper along with secondary data analyses to identify drivers of the intervention's effects. Black, Latinx, and White mothers living with HIV (mean age = 39.27, SD = 7.89) and their children (51% female, mean age = 9.65, SD = 2.48) were recruited in Southern California and Atlanta (N = 176 dyads). Following baseline assessments, half were randomized to the intervention. Follow-up assessments occurred at 3, 9, and 15 months. Implementation and quality assurance protocols revealed the need for a broad range of recruitment and retention strategies, ongoing assessment of participants' psychological distress, and joint initial training of study personnel with ongoing supervision. Based on linear growth modeling, key intervention components (i.e., parent-child communication, positive parent involvement and reinforcement, family routines) significantly contributed to disclosure self-efficacy, the primary intervention target. Lessons learned emphasized the need to balance fidelity to the research protocol with strategies for managing site-based differences and the importance of including all key intervention components for future implementation at clinical or community-based sites.
