Improving inter-rater reliability of the enhancing assessment of common therapeutic factors (ENACT) measure through training of raters.

Background: As evidence supports task-shifting approaches to reduce the global mental health treatment gap, counselor competency evaluation measures are critical to ensure evidence-based therapies are administered with quality and fidelity. Objective: This article describes a training technique for evaluating lay counselors' competency for mental health lay practitioners without rating scale experience. Methods: Mental health practitioners were trained to give the Enhancing Assessment of Common Therapeutic Factors (ENACT) test to assess counselor proficiency in delivering the Common Elements Treatment Approach (CETA) in-person and over the phone using standardized video and audio recordings. A two-day in-person training was followed by a one-day remote training session. Training includes a review of item scales through didactic instructions, active learning by witnessing and scoring role-plays, peer interactions, and trainer observation and feedback. The trainees rated video and audio recordings, and ICC values were calculated. Results: The training technique presented in this research helped achieve high counselor competency scores among lay providers with no prior experience using rating scales. ICC rated both trainings satisfactory to exceptional (ICC: .71 - .89). Conclusions: Raters with no past experience with rating scales can achieve high consistency when rating counselor competency through training. Effective rater training should include didactic learning, practical learning with trainer observation and feedback, and video and audio recordings to assess consistency.

Testing the validity of the AUDIT-C and AUDIT-3 to detect unhealthy alcohol use among high-risk populations in Zambia: A secondary analysis from two randomized trials.

BACKGROUND: This study evaluated the test characteristics of brief versions of the Alcohol Use Disorders Identification Test (AUDIT), the AUDIT-C and AUDIT-3, compared to the full AUDIT in populations with heavy drinking living in Zambia and compared differences in effect size estimates when using brief versions in clinical trials. METHODS: Data were obtained from two randomized trials of the Common Elements Treatment Approach (CETA) for reducing unhealthy alcohol use among adult couples and people living with HIV (PLWH) in Zambia. The full AUDIT was administered to participants at baseline and at 6- or 12-month follow-up. Sensitivity and specificity of the brief versions were calculated in comparison to the full AUDIT. Mixed effects regression models were estimated to calculate the effect sizes from the trials using the brief versions and these were compared to the originally calculated effect sizes using the full version. RESULTS: The AUDIT-C performed well at cut-off ≥ 3 for both men (sensitivity: >80%; specificity: >76%) and women (sensitivity: >84%; specificity: >88%). The AUDIT-3 performed best at cut-off ≥ 1, but with comparatively reduced validity for men (sensitivity: >77%; specificity: ≥60%) and women (sensitivity: ≥72%; specificity: >62%). Effect sizes were different by up to 52% using the AUDIT-C and up to 60% for the AUDIT-3 compared to the AUDIT. CONCLUSIONS: The AUDIT-C is recommended as a brief screening tool for community-based and clinic-based screening in Zambia among populations with high prevalence of unhealthy alcohol use. For research studies, the full AUDIT is recommended to calculate treatment effect.

A qualitative exploration of mechanisms of intimate partner violence reduction for Zambian couples receiving the Common Elements Treatment Approach (CETA) intervention.

RATIONALE: Despite well-established associations between alcohol use, poor mental health, and intimate partner violence (IPV), limited attention has been given to how psychological and behavioral interventions might prevent or treat IPV in low- and middle-income countries. OBJECTIVE: In a recent randomized controlled trial in Lusaka, Zambia, transdiagnostic cognitive-behavioral psychotherapy (the Common Elements Treatment Approach; CETA) demonstrated significant treatment effects on men's alcohol use and women's IPV victimization in couples in which hazardous alcohol use by the male and intimate partner violence against the female was reported. In this study, we sought to gain a more in-depth understanding of mechanisms of behavior change among CETA participants. METHODS: We conducted 50 semi-structured in-depth interviews and 4 focus groups with a purposeful sample of adult men and women who received CETA between April and October 2018. Transcripts were analyzed using an inductive constant comparison approach by a team of US- and Zambia-based coders. RESULTS: Participants described interrelated mechanisms of change, including the use of safety strategies to not only avoid or prevent conflict but also to control anger; reductions in alcohol use that directly and indirectly reduced conflict; and, positive changes in trust and understanding of one's self and their partner. Several overarching themes also emerged from the data: how gender norms shaped participants' understanding of violence reduction strategies; the role of household economics in cycles of alcohol and violence; and, deleterious and virtuous intercouple dynamics that could perpetuate or diminish violence. CONCLUSIONS: Results suggest important avenues for future research including the potential for combining CETA with poverty reduction or gender norms focused interventions and for incorporating cognitivebehavioral skills into community level interventions.
