Improving outcomes for caregivers through treatment of young people affected by war: a randomized controlled trial in Sierra Leone.

objectiveTo measure the benefits to household caregivers of a psychotherapeutic intervention for adolescents and young adults living in a war-affected area.

methodsBetween July 2012 and July 2013, we carried out a randomized controlled trial of the Youth Readiness Intervention--a cognitive-behavioural intervention for war-affected young people who exhibit depressive and anxiety symptoms and conduct problems--in Freetown, Sierra Leone. Overall, 436 participants aged 15-24 years were randomized to receive the intervention (n = 222) or care as usual (n = 214). Household caregivers for the participants in the intervention arm (n = 101) or control arm (n = 103) were interviewed during a baseline survey and again, if available (n = 155), 12 weeks later in a follow-up survey. We used a burden assessment scale to evaluate the burden of care placed on caregivers in terms of emotional distress and functional impairment. The caregivers' mental health--i.e. internalizing, externalizing and prosocial behaviour--was evaluated using the Oxford Measure of Psychosocial Adjustment. Difference-in-differences multiple regression analyses were used, within an intention-to-treat framework, to estimate the treatment effects.

findingsCompared with the caregivers of participants of the control group, the caregivers of participants of the intervention group reported greater reductions in emotional distress (scale difference: 0.252; 95% confidence interval, CI: 0.026-0.4782) and greater improvements in prosocial behaviour (scale difference: 0.249; 95% CI: 0.012-0.486) between the two surveys.

conclusionA psychotherapeutic intervention for war-affected young people can improve the mental health of their caregivers.
