Introduction
• In 2007, 34 armed conflicts• 191 million lives lost in 25 largest wars in 20th
century• 60% not engaged in fighting• 67 million displaced, out of whom 26 million
conflict-related Internally Displaced Persons
Introduction
• Psychiatric epidemiology with conflict-affected populations (Steel et al, JAMA 2009)
• 161 articles, 81,866 individuals, 40 countries• Weighted percentages: PTSD 30.6%,
depression 30.8%• Torture, potentially traumatic events, level of
political terror in country are risk factors; time since conflict associated with decrease in symptoms
Introduction
• Despite the mental health burden of political violence, and evidence for mental health treatments in developing countries, there is a lack of evidence for treatments in war-affected settings
• E.g. among children, only 4 rigorous studies have been published– 2 Bosnia (Layne et al, 2009)– 1 Uganda (Bolton et al, – 1 Indonesia (Tol et al, 2008)
Methods: Intervention• A secondary preventive
intervention; aimed at children with psychosocial problems, at risk of developing disorders
• Combining:– Symptom reduction (e.g.
PTSD, depression, anxiety)– Strengthening resilience
(e.g. hope, coping, social support)
Methods: Intervention• Structured intervention: 15
sessions over 5 weeks (specific themes)
• In classrooms with groups of around 15 children
• Combining cognitive-behavioral techniques (psycho-education, safety building, relaxation, exposure-based techniques) with creative-expressive therapy techniques
Methods
• As part of a larger public health project for children in war-affected settings www.psychosocialcarechildren.org
• School-aged children in Burundi, Indonesia, Nepal, and Sri Lanka

Discussion
• Appropriateness of (resilience) measures, in comparison with community feedback
• Influence of context on efficacy of treatment• Gender differences• Further work on treatment mechanisms• Debate on universal/selective vs. indicated
interventions, must be informed by yet to be proven protective & risk indicators
