简要总结
In South Africa, the country with the highest HIV prevalence (19%), co-occurring problems such as depression, post-traumatic stress, and food insecurity interact to enhance one another (i.e., syndemic problems) and are associated with worse HIV outcomes such as worse antiretroviral therapy (ART) adherence and worse viral load. This study proposes to: 1) explore how syndemic problems work together to make health worse for people with HIV (PWH) and explore what people think about a potential treatment; 2) develop a treatment to address syndemic problems and improve ART adherence (CBT-SA); 3a) assess whether people are willing to receive the CBT-SA we it can actually be done; and 3b) identify factors that make it easier or more difficult to receive CBT-SA.
详细描述
South Africa (SA) has a generalized HIV epidemic, and the highest HIV prevalence rate (19%). Psychosocial (e.g., depression, post-traumatic stress) and structural problems (e.g., food insecurity) are associated with worse antiretroviral therapy (ART) adherence and higher viral load. Depression, post-traumatic stress, and food insecurity are also highly comorbid and are thought to interact synergistically to confer greater risk for worse HIV outcomes (i.e., syndemic problems). The proposed specific aims are to: 1) explore the complex interrelationships between food insecurity, depression, and post-traumatic stress, as they relate to engagement in HIV care, and explore attitudes to potential intervention components; 2) develop a multilevel intervention to address syndemic problems and improve adherence (CBT-SA) and conduct an iterative proof-of-concept pilot trial use syndemic theory; 3a) assess the feasibility and acceptability of CBT-SA in a pilot RCT; and 3b) identify barriers and facilitators of CBT-SA engagement among PWH and uptake among care providers and other key local partners to inform a future hybrid effectiveness/implementation R01 trial. If successful, this intervention would be further tested for effectiveness and implementation in a future application.

研究组 & 干预措施
Cognitive Behavioral Therapy for Syndemics and Adherence (CBT-SA)
We anticipate the intervention condition (CBT-SA) will contain the following: cognitive behavioral therapy for syndemics and adherence (CBT-SA; n=30) likely will be comprised of both psychosocial and structural intervention components, based on the results of Aim 1 and refinement in Aim 2. In addition to food parcels, we expect the CBT-SA condition will also receive nutritional counseling, linkage to care, and case management. Only the CBT-SA condition will receive the psychological intervention for depression and PTSD and adherence counseling. Specific intervention components will be informed by prior aims.
干预措施: Cognitive Behavioral Therapy for Syndemics and Adherence (CBT-SA) (Behavioral)
Enhanced Treatment as Usual (ETAU)
We anticipate the control condition will contain the following: the enhanced treatment as usual (ETAU; n=30) will consist of PWH receiving treatment at their HIV primary care clinic as usual, enhanced by supplemental food parcels and referrals for mental health care and food service organizations. Treatment as usual for mental health care is evaluation by a nurse and referral to a medical officer or to a traveling psychologist available 1 day per week. Because there is no standard of care for food insecurity, we propose that all participants will receive food parcels, but ETAU participants will not receive case management or psychosocial intervention.
结局指标
主要结局
75% of the participants randomized to CBT-SA attend the 6-month follow-up visit.
时间窗: 6-month follow-up
We will calculate the percentage of participants randomized to the CBT-SA condition who attend the 6-month follow-up visit. CBT-SA will be considered feasible and acceptable if 75% of the participants attend the 6-month follow-up visit.
75% of participants randomized to CBT-SA attend at least 66% of the sessions
时间窗: 6-month follow-up
We will calculate the percentage of participants randomized to the CBT-SA condition who attend 66% or greater of the total number of sessions. CBT-SA will be considered feasible and acceptable if 75% of the participants attend 66% or more of the sessions.
次要结局
- ART adherence(6-month follow-up)
- Presence of depression measured by the DIAMOND diagnostic instrument(6-month follow-up)
- Presence of PTSD measured by the DIAMOND diagnostic instrument(6-month follow-up)
