Mindfulness and Acceptance Based Therapy for Adolescents Living With HIV

Overview

Adolescents represent a growing share of people living with HIV in sub-Saharan Africa (SSA), yet show poor adherence to medication and viral suppression (VS) compared to adults. Investigators postulate that to achieve optimal adherence, support interventions that resonate with life-stages changes in adolescence need to be tested and promoted. Mindfulness and acceptance based interventions are slowly gaining traction as appropriate for adolescents. The study proposes to explore acceptability of an adapted mindfulness and acceptance-based psychosocial intervention (acceptance and commitment therapy: Discoverer, Noticer, Advisor-values model-ACT-DNA-v), among providers (health care practitioners -HCPs) and users (adolescents living with HIV/AIDS-ALWHA). Further, it endeavors to measure feasibility and effectiveness of ACT-DNA-v in reducing psychological barriers to adherence among ALWHAs. The study is to be conducted at two public health centers in Kampala-Uganda. The study design is exploratory sequential mixed-methods; where qualitative data is to be used to explore acceptance of ACT-DNA-v, while quantitative data will be used to measure feasibility of the intervention and its effectiveness in reducing psychosocial barriers to adherence. Qualitative exploratory methods will guide exploration of acceptability of ACT-DNA-v among users and providers; collecting data with a semi-structured interview on domains of inquiry including; understanding, satisfaction, intention to use and perceived appropriateness of ACT-DNA-v. A randomized control trial with quantitative surveys at baseline, post-intervention and follow-up will used to measure the effects of the intervention on process and clinical outcomes among ALWHA. Thematic data analysis will be used to analyze qualitative data, while T-test, Wilcoxon rank sum test, Fisher's exact and Chi-square tests respectively will be used to ascertain average mean differences between the ACT group and the control group on the outcome parameters.

Background The success of antiretroviral therapy (ART) is highly dependent on adherence and persistent care engagement. However, despite efforts to improve sustained ART use among adolescents, non-adherence persists. Studies using medication possession ratios and clinical counts have found adherence to ART among adults to be at 72% compared to 68% among young people, furthermore, statistics on VL measures in 2017 show that 74.2% of adults above 50 years had achieved viral load suppression compared to 39.6% of adolescents. Additionally, almost 50% of HIV cases in Uganda are among young people. Poor adherence among ALWHA undermines the HIV care cascade and efforts to end the AIDS epidemic by 2030. As a consequence, young people are the only group in Uganda among whom HIV mortality is increasing. The unique developmental changes at the onset of adolescence have been cited as main factors influencing psychosocial pathways into health, resulting in psychopathological barriers to medication adherence among ALWHA. Developmentally appropriate psychosocial interventions need to be added into adolescents' HIV care. However, to date, psychosocial support interventions targeted for the unique developmental changes in adolescence remain limited. Most interventions in use with young people are developed for adult populations, despite adult-focused interventions being shown to have limited effectiveness among young people. Besides, some interventions like short message services are expensive and difficult to sustain, while others lack a clear mechanism of change for replication. Mindfulness and acceptance based interventions, specifically ACT-DNA-v, are developmentally appropriate for adolescents because they are designed to promote emotion regulation and values consistent living, counteracting the imbalance created by developmental changes amidst undeveloped executive functions such as judgment. Besides, ACT-DNA-v relies on use of art and metaphors which serve as aids to symbolic reasoning (a change instigated by adolescence). The intervention is also centered around values and adolescence is a stage of establishing identity. Finally, ACT-DNA-V has a proper mechanism of change called psychological flexibility, thus, it can easily be replicated. However, while mindfulness and acceptance based interventions have been found to be effective in improving mental health of adolescents in the developed world, they have not been tested in resource limited settings, with adolescents living with HIV and for outcomes beyond mental health. Thus, this study set out to adapt ACT-DNA-v for use in a resource limited setting, explore its acceptability among users (ALWHAs) and providers (HCPs), measure its feasibility when used with adolescents and evaluate its impact on reducing psychosocial barriers to adherence, improve self-reported adherence and reducing viral load. Study Objectives The study aims to achieve the following objectives; .To adapt and explore acceptability of ACT-DNA-v among users (ALWHA) and providers (HCPs). .To measure feasibility of the adapted ACT-DNA-v for use with ALWHA. .To examine the impact of ACT-DNA-v on reducing proximal psychosocial barriers to medication adherence (depression, anxiety and stigma) among ALWHA. .To measure effectiveness of a mindfulness based intervention (ACT-DNA-v) on self-reported adherence among ALWHA in Kampala, and ascertain its impact on viral load reduction via analysis of data from medical records Hypothesis .Participants receiving the ACT-DNA-v intervention will report a significant reduction in depression, anxiety \& stigma at four months' follow-up as compared to participants in the control group. .Participants receiving the ACT-DNA-v intervention will have significantly higher levels of reported ART adherence and lowered viral load at four months' follow-up compared to participants not receiving this intervention. Methods Overall design To achieve the study goals, a mixed methods design will be used, specifically exploratory sequential. The mixing is intended for purposes of expansion (where qualitative data will explore acceptability of the mindfulness based intervention and quantitative data measures if the accepted intervention is effective). This will improve the usefulness of the findings, (qualitative data evaluating the process while quantitative data evaluate the outcomes). The study will involve two sub-studies; formative/qualitative study and intervention/quantitative study.
