The Effect of Interventions on Functional Impairment in Youth Exposed to Mass Trauma: a Meta-Analysis

The impact of mental health and psychosocial support programmes on children and young people's mental health in the context of humanitarian emergencies in low- and middle-income countries: A systematic review and meta-analysis

Humanitarian emergencies pose a significant global health challenge for children and young people's mental and psychological health. This systematic review investigates the effectiveness of mental health and psychosocial support (MHPSS) programmes delivered to children and young people affected by humanitarian emergencies in low- and middle-income countries (LMICs). Twelve electronic databases, key websites and citation checking were undertaken. Forty-three randomised controlled trials (RCTs) published in English between January 1980 and May 2023 were included in the review. Overall, the findings suggest that cognitive behavioural therapy may improve depression symptoms in children and young people affected by humanitarian emergencies. Narrative exposure therapy may reduce feelings of guilt. However, the impact of the other MHPSS modalities across outcomes is inconsistent. In some contexts, providing psychosocial programmes involving creative activities may increase the symptoms of depression in children and young people. These findings emphasise the need for the development of MHPSS programmes that can safely and effectively address the diverse needs of children and young people living in adversarial environments.

A Critical Review of Effective Child Mass Trauma Interventions: What We Know and Do Not Know from the Evidence

Over the last 20 years, numerous interventions have been developed and evaluated for use with children exposed to mass trauma with six publications reporting meta-analyses of randomized controlled trials of child mass trauma interventions using inactive controls to examine intervention effects on posttraumatic stress, depression, anxiety, and functional impairment. The current report reviews the results of these meta-analytic studies to examine the status of the evidence for child mass trauma mental health interventions and to evaluate potential moderators of intervention effect and implications for practice. The meta-analyses reviewed for the current report revealed a small to medium overall effect of interventions on posttraumatic stress, a non-statistically significant to small overall effect on depression, a non-statistically significant overall effect on anxiety, and a small overall effect on functional impairment. The subgroup analyses suggest that interventions should be matched to the populations being served and to the context. Additional research is needed to tailor future interventions to further address outcomes other than posttraumatic stress including depression, anxiety, and functional impairment.
