Counseling for Alcohol Problems in Pregnancy (CAP-Pre) Phase II (CAP-Pre)

February 25, 2025 updated by: Daniela C. Fuhr, Leibniz Institute for Prevention Research and Epidemiology - BIPS GmbH

Purpose: This study is testing a new counseling program called Counselling for Alcohol Problems in Pregnancy or CAP-Pre, designed to help pregnant women in South Africa to reduce their alcohol use and improve their well-being. Alcohol use during pregnancy can harm babies, leading to Fetal Alcohol Spectrum Disorders (FASD), which can cause lifelong health and developmental problems. Currently, there are no community-based support programs to help pregnant women struggling with alcohol use.

What Happens in the Study? 40 pregnant women will take part in the study and will be randomly assigned to one of two groups:

  1. CAP-Pre + Standard Health Advice - Women will receive five counseling sessions to help them reduce drinking, plus usual pregnancy care.
  2. Standard Health Advice Only - Women will receive usual pregnancy care and an information booklet on alcohol use in pregnancy.

The study will test:

The study will evaluate if CAP-Pre is easy to deliver, acceptable, and helps women to drink less. (measured by self-report and a blood test).

Why Is This Important? South Africa has the highest rates of FASD in the world, but most pregnant women do not receive specialized support for harmful alcohol use. If this pilot study is successful, it will help prepare for a more extensive study to test whether CAP-Pre can be widely used in antenatal care programs.

Who Is Involved? The study is run by researchers from Germany and South Africa, with funding from the German Alliance for Global Health Research.

Study Overview

Detailed Description

South Africa has the highest prevalence of Fetal Alcohol Spectrum Disorders (FASD) globally, with alcohol use during pregnancy being prevalent in low-resource settings. However, there is no structured, community-based psychological support available for pregnant women who consume alcohol at harmful levels. The Counselling for Alcohol Problems in Pregnancy (CAP-Pre) intervention is a brief psychological counseling program designed to:

  • Support pregnant women in reducing alcohol use through motivational interviewing (MI) and cognitive-behavioral techniques (CBT).
  • Improve maternal well-being by addressing underlying stressors and barriers to change.
  • Be delivered by community health workers (CHWs) in a scalable, task-shifted approach.

This pilot randomized controlled trial (RCT) aims to evaluate the CAP-Pre intervention's perceived effectiveness, feasibility, and acceptability in preparation for a definitive RCT.

Study Design Type: Parallel-arm, single-blind, individually randomized controlled trial (RCT).

Setting: Community-based antenatal care program, Cape Flats, Western Cape, South Africa.

Participants: 40 pregnant women screened for the following eligibility criteria

Inclusion:

  • ≥18 years old, ≤28 weeks pregnant.
  • AUDIT score 8-20 (indicating hazardous alcohol use).

Exclusion:

  • Severe psychiatric disorders.
  • High-risk pregnancy complications. Recruitment Sites: Community outreach and antenatal clinics.

Randomization: 1:1 allocation to:

  • CAP-Pre + Enhanced Usual Care (EUC) (Intervention)
  • Enhanced Usual Care (EUC) only (Control) Intervention and Control Groups Intervention: CAP-Pre + Enhanced Usual Care (EUC) (n=20) Five structured 60-minute counseling sessions (weekly, CHW-delivered).

Key components:

Motivational interviewing (MI) to enhance behavior change. Cognitive-behavioral strategies (CBT) for managing alcohol cravings. Goal-setting and self-monitoring for tracking progress. Problem-solving techniques and social support enhancement. Control: Enhanced Usual Care (EUC) (n=20) Information booklet on alcohol use in pregnancy. Referral to antenatal services if needed. No structured counseling was provided.

Data Collection and Outcome Measures

Data Collection Timeline:

Baseline assessment before randomization and Post-intervention assessment on alcohol use, mental health, and qualitative feedback Primary Outcomes

Reduction in alcohol consumption measured through:

Self-Reported Alcohol Use: Alcohol consumption will be assessed using the Alcohol Timeline Follow Back (TLFB) method to estimate daily drinking volume over the past months.

Secondary Outcomes

  1. Biological Markers for alcohol consumption: Phosphatidyl ethanol (PeTH) through Dried Blood Spot (DBS) Collection. PeTH is a direct biomarker of alcohol consumption that is formed only in the presence of ethanol. It is highly specific and sensitive in detecting alcohol use over the past 2-3 weeks.
  2. Psychosocial Functioning: Assessed using the WHO-Disability Assessment Schedule (WHO-DAS). WHO-DAS 2.0 is a standardized instrument developed by the World Health Organization (WHO) to assess functional impairment and disability across multiple life domains. It evaluates the impact of mental and physical health conditions on daily activities and social participation.
  3. Depressive Symptoms: Evaluated using the Edinburgh Postnatal Depression Scale (EPDS). EPDS is a 10-item self-report measure designed to screen for perinatal depression in pregnant and postpartum women.
  4. Alcohol-Related Consequences: Measured with the Alcohol Use Disorder Identification Test - Consumption (AUDIT-C). AUDIT-C is a brief, 3-item screening tool derived from the full 10-item Alcohol Use Disorders Identification Test (AUDIT) to identify individuals at risk for hazardous drinking and alcohol use disorders (AUDs).
  5. Family and Social Support: Assessed using a 10-item structured questionnaire measuring the availability and perceived adequacy of social support across various domains, such as emotional, instrumental, and informational support.
  6. Perceived Usefulness of Counselling: Evaluated through qualitative pre and post-intervention interviews, exploring participant expectations, experiences, perceptions of counseling, and perceived benefits or challenges.

Baseline Covariates:

Additional Covariates Collected at Baseline

  1. Demographic and Socioeconomic Information: Age, education, and socioeconomic status.
  2. Substance Use and Risk Factors: Self-reported past-month use of tobacco and other substances.
  3. Partner Substance Use: Self-reported data on household and partner alcohol/drug use.
  4. Intimate Partner Violence (IPV) & History of Trauma: Self-reported experiences of violence, abuse, and health-related risks.
  5. Childhood Adversity and Life Stressors: Self-reported early trauma and current stressors.

Analysis Plan We will analyze and report data following CONSORT guidelines for pilot and feasibility trials. Analyses for the pilot RCT will mainly be descriptive to describe recruitment and response rates, process data, and retention at 3 months.

Ethical Considerations This study poses minimal risks, including minor discomfort from blood sampling and potential mental distress during sessions. Confidentiality will be protected through strict data security, staff confidentiality agreements, and ethical training. PeTH blood collection will follow infection control protocols and be conducted by trained staff. Mental distress risks will be minimized through participant choice, referrals for support, and staff supervision. The study has ethical approval from the South African MRC, and participation is voluntary, with the right to withdraw at any time.

Output A contextually adapted program of care (called CAP-PRE) for pregnant women who misuse alcohol that can be tested for effectiveness and cost-effectiveness in a larger, definitive RCT.
