Sub-Trial of the Youth Readiness Intervention (YRI): Treatment of Control Group and Addition of Stress Biomarkers

Summary

This research is a continuation of the Youth Readiness Intervention (YRI) randomized clinical trial by adding additional pre and post intervention data collection upon treatment of the control group (N=222) with the intervention which was proven effective in the larger trial. The overall research has investigated whether participation in the YRI intervention will improve emotional regulation, prosocial attitudes/behavior, social support and daily and functioning among war-affected 15-24 year olds in Sierra Leone. In this sub-study which will involve treatment of the control group with the effective YRI intervention, the investigators will add an additional measure of self-regulation as observed via DNA methylation in buccal cells collected via cheek swabs. As before, after the YRI intervention, youth will be offered a free educational opportunity at the EducAid program in Freetown or in one of its upline/provincial sites. This stage of the research, as in the treatment with the main group, will test whether youth enrolled in the YRI psychosocial intervention go on to demonstrate improved attendance and behavior in a subsidized education program. In the previous phase of the trial, the investigators did observe significant effects for the YRI intervention and evidence that the program is indeed effective. For instance, post-intervention, YRI youth reported greater improvements in emotion regulation (β=0.109, 95%CI 0.026 to 0.191, δ=0.31), prosocial attitudes/behaviors (β=0.149, 95%CI 0.057 to 0.240, δ=0.38), and social support (β=0.119, 95%CI 0.009 to 0.229, δ=0.26) than controls, and greater reductions in functional impairments (β= -0.175, 95%CI -0.299 to -0.050, δ= -0.35). Differences in symptoms were non-significant at six-month follow-up for the full sample; moderator analyses showed that, for individuals in the top quartile of baseline symptoms, YRI youth had greater improvements in emotion regulation and social support than controls. At eight-month follow-up, teachers reported that YRI participants were 8.9 times more likely to be in school (28.8% v. 4.7%) and showed better attendance (β=3.553, 95%CI 0.989 to 6.118, OR=34.93) and academic performance (β= -0.954, 95%CI -1.807 to -0.102, δ= -1.31).

In this final phase of the trial as the investigators treat the wait list control group, the investigators will test whether intervention effects observed in self-report data on improved emotion-regulation are also upheld in biomarker data. Thus, the investigators will now provide YRI treatment to the wait list control group and employ the use of biomarkers as a measure of the intervention's effectiveness. The objective of the study will be to assess whether DNA methylation (collected via cheek swabs of buccal cells) is associated with changes in emotion regulation pre- and post- intervention. The aim is to test the hypothesis that the YRI is associated with improvements emotion-regulation evidence both in self-report data on emotion-regulation and in buccal cell DNA methylation. This study will add to the evidence base for effective, culturally sensitive mental health services for youth and young adults affected by war and other forms of adversity.

Interventions

BEHAVIORAL

Youth Readiness Intervention

The YRI brings together six empirically-supported practice elements shown to be efficacious across different mental health interventions, as well as methods intended to socialize youth and improve self-efficacy. Practice elements address the broad scope of problems evidenced in Sierra Leonean war-affected youth and enhance the YRI's pacing, which progresses through three phases traditionally used in trauma treatments (stabilization, integration, connection). The weekly intervention takes place over 12 sessions lasting approximately one hour and a half. Groups are divided by gender and age. Each group is paired with two interventionists of the same gender.
