Using Adapted Dialectical Behavior Skills as Mental Health Prevention in Post-Earthquake Nepal: READY-Nepal Protocol for a Pilot Feasibility and Acceptability Trial

SETTING: The study will be conducted in school settings in earthquake -affected areas throughout the Kathmandu Valley. Due to an aggregation of factors including political and environmental trauma, these areas are at high risk for the development and continuation of mental health problems.

STUDY DESIGN: Regulating Emotions through Adapted Dialectical behavior skills for Youth in Nepal (READY-Nepal) is a pilot quasi-experimental trial. All students between the ages of 13 to-17 enrolled in a secondary school in one of two earthquake -affected districts in the Kathmandu Valley will be eligible for participation. After enrollment, classes will be assigned to either READY-Nepal or a wait-list control condition. Groups will be gender-stratified due to concerns around stigma and confidentiality found in similar trials in Nepal and other low- and middle-income countries (LMIC). Because of the higher potential for contamination effects (i.e., transmission of skills or related intervention content) at the individual level, whole classroom sections will either be assigned to the experimental or waitlist conditions. Because of the pilot nature of this preliminary feasibility and acceptability trial, the sample size will not be powered for inference testing. Results from this pilot study will be used to identify parameters necessary for an appropriately powered cluster- randomized trial (CRT) of the intervention.

INTERVENTIONS: READY-Nepal is a 10 -session, classroom- based skills training program designed to promote positive mental health in addition to supporting resilient responses in trauma- exposed adolescents. The modularized, emotion-focused intervention was informed by principles of Dialectical Behavior Therapy (DBT) and was designed to augment and generalize Nepali adolescents' emotion regulation abilities during current or future stressful circumstances. READY-Nepal is divided into 5 components, and includes both didactic and experiential instruction in skills related to mindfulness, stress tolerance, emotional awareness and regulation, validation of self and others, and mastery of interpersonal relationships. The program was designed with a flexible delivery format in mind, in order to increase its dissemination potential in LMIC like Nepal. The program was developed from a prior, more intensive version of the intervention that was culturally adapted and piloted with self -destructive women in rural Nepal. READY-Nepal will be delivered by local Nepali clinical counselors trained by a US psychiatrist and clinical psychology doctoral student with comprehensive DBT training. Program facilitators will participate in weekly ongoing supervision with the original program developers.

PARTICIPANTS: School- going adolescents (ages 13- to 17) residing in earthquake-exposed areas in Kathmandu Valley are the intended direct beneficiaries of READY-Nepal. For this feasibility and acceptability pilot, additional qualitative component participants will include school teachers and primary caregivers of a subset of participating adolescents.

PLANNED ANALYSES Statistical analyses: Primary and secondary outcomes of interest will be summarized descriptively and visually over time for both study arms. Total and validated domain- specific scores will be evaluated for each instrument. Outcomes will be analyzed for within -group factor and intervention as a between- group factor. Preliminary estimates of within- and between -group variances and the intra-class correlation coefficient (ICC) of participant outcomes will be estimated and used to determine sample size calculations for a future, adequately powered cluster -randomized trial.
