Study of Effectiveness and Implementation of Different Versions of the CETA Mental Health Intervention Among Internally Displaced Persons (IDPs) and Veterans in Ukraine

This research team developed the CETA intervention and has evaluated its effectiveness in multiple trials. CETA was developed based on other transdiagnostic interventions that have proven efficacious in the United States and Europe. Briefly, full length CETA includes 12 weekly treatment sessions comprised of cognitive behavioral elements. In the last few years, as more researchers have identified mental health interventions that can successfully reduce the burden of symptoms for clients in low-resource settings, there has been a push to develop intervention models that are more scalable. One of the barriers to scalability may be duration of treatment, as clients may not complete treatment if there are too many sessions, and counselors may be limited in the number of clients they can treat over the course of a year when each client requires more sessions. However, the trade-off of potential reduction in treatment efficacy has not been evaluated for shortened- versus standard-length treatment models of efficacious interventions. This study will begin to address this by testing to see if both the long and a short version of CETA are effective compared to wait-control condition. Community providers from the three trial sites (Kyiv, Kharkiv, and Zaporizhia) have begun ongoing training in CETA as counselors and local supervisors.

This study will be conducted as a 3-armed randomized controlled trial. Adult IDPs, Ukrainian military veterans, and their family members in 3 Ukrainian cities, Kyiv, Kharkiv, and Zaporizhia, will be recruited on a rolling basis and screened to identify those with elevated depression and/or posttraumatic stress (PTS) symptoms and impaired functioning using a locally validated assessment instrument. Local non-governmental organizations (NGOs) and existing service providers have been provided with a locally validated short clinical assessment instrument (developed during a previous phase of the current research). As part of regular services, these organizations will use this instrument to assess their clientele for need for specific clinical services. If the assessment suggests that the person is in need of services and the person agrees to seek help they will then refer them to the study's monitoring and evaluation (M&E) staff who will meet with each potential participant and conduct a repeat screening to ensure trial eligibility. Those who meet the eligibility criteria on this second screen will be consented for the study. All eligible and consented adults will be randomly allocated to either a wait-list control condition, the Brief CETA model, or the Full CETA model. After randomization, those allocated to either CETA arm will be referred to one of the local counselors or supervisors, all of whom are trained in both versions of CETA (Brief and Full). for purposes of blinding those allocated to a CETA arm (and their counselors) will not be aware of whether they are receiving the full CETA (12 sessions) or the short CETA (5 sessions). This information will be revealed to the provider and client after the 4 session, so that they can plan either to end treatment at the 5th session or continue. All study participants in all 3 arms will be assessed on a monthly basis for 6 months post-baseline. After completion of their participation in the trial those assigned to the wait-control condition will be able to receive CETA services.

At the 1st monthly data collection point post treatment completion, study participants in the short CETA and long CETA intervention arms will also be interviewed using a Client Dissemination and Implementation Research (D&I) instrument that explores aspects of program implementation from the client perspective. In addition, the first 30 participants (total N=60) to complete both versions of CETA will also be asked to provide a qualitative interview upon completion of their treatment exploring unexpected effects of the program, both positive and negative. Data from these D&I interviews will be used to improve the program. Data from the qualitative interview will also be used generate additional locally important items to add to the study impact assessment instruments. This expanded version of the instrument will be completed by later study participants.

CETA providers (counselors and supervisors) will be interviewed after 6 months of providing CETA services using both a Provider Dissemination and Implementation (D&I) instrument and a qualitative interview. The purpose of the provider D&I instrument is similar to that for the clients, but from the provider perspective (i.e., to identify aspects of program implementation that should be changed in order to improve the program). The purpose of the qualitative interview is the same as the D&I instrument but to identify unknown factors affecting implementation that are not referred to in the instrument. important local information from the latter will not be added to the D&I instrument but will be included in reports as qualitative data only.
