Multisite longitudinal efficacy trial of a disclosure intervention (TRACK) for HIV+ mothers: An update

BackgroundThe Teaching, Raising, And Communicating with Kids (TRACK) intervention full-scale longitudinal efficacy trial was published in 2021 and was based on a previously successful pilot intervention published in 2011. The TRACK intervention assists mothers living with HIV (MLH) with serostatus disclosure to their young children. In the publication reporting the full-scale trial, TRACK MLH were four times more likely to disclose their HIV serostatus than controls, with the rate increasing to six times more likely applying GEE logistic regression. Intervention MLH showed improvements in communication, social support, family routines, and disclosure self-efficacy; they also demonstrated decreased anxiety and better physical and mental health scores; and their children reported significantly more decline in worry than controls. MethodsThis preprint presents recent analyses showing increases in the reported HIV disclosure rates over and above those reported in the full-scale trial, due to additional follow-up datapoints received after the 2021 publication. ResultsFor MLH in the intervention group, disclosure is 37.6% compared to 34.1% from the 2021 publication, and 12.1% in the control condition compared to 11%. Odds of disclosing if participants were in the intervention group are 4.39 (95% CI. = 2.0, 9.5) compared to 4.20 (95% CI. = 1.8, 9.3), with the intervention group 30% more likely to disclose compared to the 28% reported in 2021. Regarding site disclosure rates for the intervention group, the California disclosure rate is 43.6% compared to 35.9% previously reported; Georgias site rate remained unchanged. ConclusionsThese updates are now included in our final analysis dataset and show the intervention was more successful than previously reported.
