Zambia Common Elements Treatment Approach Pilot Study

Study Overview
=================
Brief Summary
-----------------
This is a randomized controlled trial (RCT) evaluating the effectiveness of an alcohol brief intervention alone compared to the brief intervention plus an evidence-based psychotherapy (CETA) in reducing alcohol misuse and co-occurring mental health problems among persons with HIV in Zambia.

Detailed Description
-----------------
Alcohol misuse is a major unaddressed barrier to ending the HIV/AIDS epidemic. Hazardous drinking increases HIV transmission, delays antiretroviral therapy (ART) uptake, reduces adherence and retention, and increases mortality. Comorbid mental health or substance misuse, similar to alcohol use alone, can also significantly undermine HIV treatment. The vast majority of people living with HIV globally live in low- and middle-income countries (LMIC). Similar to most HIV care settings in LMIC, in Zambia, the location of the current study, there are no readily available evidence-based treatments for alcohol misuse or mental health problems. This study will enroll persons living with HIV (PLWH) who have alcohol misuse in Zambia. Participants will be recruited and screened during regular HIV care visits. Participants will be recruited by their regular care providers (i.e., peer educators, counselors, nurses, physicians) and referred to study staff if they are interested. The investigators anticipate enrolling up to 320 participants, all of whom have hazardous alcohol use. N=160 participants will be high-risk drinkers due to having either a moderate-to-severe alcohol use disorder or mental health comorbidities, or both. These participants will be randomized into the RCT. Participants who have hazardous alcohol use (but not a moderate-to-severe AUD) without mental health comorbidities (a lower risk group of participants) will not be enrolled into the RCT but will be tracked as part of a parallel cohort study. The minimum age of research subjects will be 18. Eligibility will be assessed via audio computer assisted self-interviewing (ACASI). Participants in the 'cohort study' (i.e., lower risk participants) will receive a brief alcohol intervention. Participants in the RCT (i.e., higher risk participants) will be randomly assigned on a 1:1 basis (stratified by gender) to receive the brief intervention alone or the brief intervention plus CETA. All participants will be evaluated for outcomes at baseline and at a six month follow-up visit. For RCT participants, the investigators will compare the effectiveness of the brief intervention alone to the brief intervention plus CETA in reducing alcohol misuse and mental health problems. For cohort participants, the investigators will collect preliminary data on whether alcohol misuse reduced at the six month follow-up but there will be no comparison/control group. The findings from this pilot study will be used to inform future programming and research in Zambia and other LMIC to implement screening, brief intervention, and referral to treatment (SBIRT) programs for alcohol use in HIV care.

Masking: Single


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Brief Intervention (BI)<br>30 minute alcohol brief intervention delivered by lay provider during HIV clinic visit. | Behavioral: Brief Intervention<br>* The BI used in the trial combines motivational interviewing skills with cognitive behavioral therapy elements in order to assist clients with self identified substance misuse to begin to consider changing their rates of drinking and drug use. The intervention lasts 30 to 40 minutes and consists of 5 components including: 1) screening 2) identification and information on the impacts of substance misuse 3) talking about change and goal setting 4) understanding the primary reason for drinking 5) skill building with practice and 6) referral for services.<br>|
| Experimental: Brief Intervention + CETA<br>30 minute alcohol brief intervention delivered by lay provider during clinic visit followed by 6-12 weekly sessions of CETA. | Behavioral: Brief Intervention<br>* The BI used in the trial combines motivational interviewing skills with cognitive behavioral therapy elements in order to assist clients with self identified substance misuse to begin to consider changing their rates of drinking and drug use. The intervention lasts 30 to 40 minutes and consists of 5 components including: 1) screening 2) identification and information on the impacts of substance misuse 3) talking about change and goal setting 4) understanding the primary reason for drinking 5) skill building with practice and 6) referral for services.<br>Behavioral: Common Elements Treatment Approach (CETA)<br>* The Common Elements Treatment Approach, or CETA, is a transdiagnostic psychotherapy based on cognitive behavioral elements for mood, anxiety and trauma related problems, and for alcohol and substance misuse. CETA is based on the fact that most evidence-based mental health treatments (EBTs) consist of similar components. The objective of CETA is to provide a single training in a range of therapy components that are similar across EBTs and to then teach counselors how to design a specific course of treatment for each client based on the client's presenting problems.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Alcohol Use Disorders Identification Test (AUDIT) Scale Score From Baseline to 6-month Post-baseline. | AUDIT is a 10-item measure of hazardous alcohol use with possible range of 0-40 (total scale score). Higher scores are associated with more hazardous use. | Baseline and 6 months post-baseline | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Center for Epidemiological Studies-Depression (CES-D) Scale Score From Baseline to 6-month Post-baseline. | CES-D is a 20-item scale of depression with a possible range of 0-60 (total scale score). Higher scores are associated with greater depression symptom severity. | Baseline and 6 months post-baseline | 
| Change in Harvard Trauma Questionnaire (HTQ) Post-traumatic Stress Disorder (PTSD) Symptom Scale Score From Baseline to 6-month Post-baseline. | The HTQ is a 39-item PTSD symptom scale with possible range of 1-4 (average scale score). Higher scores are associated with greater PTSD symptom severity. | Baseline and 6 months post-baseline | 
| Number of Participants With Any Recent Substance Use. | Any recent substance use will be defined as any use of the following substance types in the past 3 months: inhalants, marijuana, cocaine, amphetamines, sedatives, hallucinogens, opioids. | 6 months post-baseline |
