Mental health and psychosocial support in humanitarian settings: linking practice and research

This review links practice, funding, and evidence for interventions for mental health and psychosocial wellbeing in humanitarian settings. We studied practice by reviewing reports of mental health and psychosocial support activities (2007-10); funding by analysis of the financial tracking service and the creditor reporting system (2007-09); and interventions by systematic review and meta-analysis. In 160 reports, the five most commonly reported activities were basic counselling for individuals (39%); facilitation of community support of vulnerable individuals (23%); provision of child-friendly spaces (21%); support of community-initiated social support (21%); and basic counselling for groups and families (20%). Most interventions took place and were funded outside national mental health and protection systems. 32 controlled studies of interventions were identified, 13 of which were randomised controlled trials (RCTs) that met the criteria for meta-analysis. Two studies showed promising effects for strengthening community and family supports. Psychosocial wellbeing was not included as an outcome in the meta-analysis, because its definition varied across studies. In adults with symptoms of post-traumatic stress disorder (PTSD), meta-analysis of seven RCTs showed beneficial effects for several interventions (psychotherapy and psychosocial supports) compared with usual care or waiting list (standardised mean difference [SMD] -0·38, 95% CI -0·55 to -0·20). In children, meta-analysis of four RCTs failed to show an effect for symptoms of PTSD (-0·36, -0·83 to 0·10), but showed a beneficial effect of interventions (group psychotherapy, school-based support, and other psychosocial support) for internalising symptoms (six RCTs; SMD -0·24, -0·40 to -0·09). Overall, research and evidence focuses on interventions that are infrequently implemented, whereas the most commonly used interventions have had little rigorous scrutiny.

Comparison of mental health between former child soldiers and children never conscripted by armed groups in Nepal.

CONTEXT Former child soldiers are considered in need of special mental health interventions. However, there is a lack of studies investigating the mental health of child soldiers compared with civilian children in armed conflicts. OBJECTIVE To compare the mental health status of former child soldiers with that of children who have never been conscripts of armed groups. DESIGN, SETTING, AND PARTICIPANTS Cross-sectional cohort study conducted in March and April 2007 in Nepal comparing the mental health of 141 former child soldiers and 141 never-conscripted children matched on age, sex, education, and ethnicity. MAIN OUTCOME MEASURES Depression symptoms were assessed via the Depression Self Rating Scale, anxiety symptoms via the Screen for Child Anxiety Related Emotional Disorders, symptoms of posttraumatic stress disorder (PTSD) via the Child PTSD Symptom Scale, general psychological difficulties via the Strength and Difficulties Questionnaire, daily functioning via the Function Impairment tool, and exposure to traumatic events via the PTSD Traumatic Event Checklist of the Kiddie Schedule of Affective Disorders and Schizophrenia. RESULTS Participants were a mean of 15.75 years old at the time of this study, and former child soldiers ranged in age from 5 to 16 years at the time of conscription. All participants experienced at least 1 type of trauma. The numbers of former child soldiers meeting symptom cutoff scores were 75 (53.2%) for depression, 65 (46.1%) for anxiety, 78 (55.3%) for PTSD, 55 (39.0%) for psychological difficulties, and 88 (62.4%) for function impairment. After adjusting for traumatic exposures and other covariates, former soldier status was significantly associated with depression (odds ratio [OR], 2.41; 95% confidence interval [CI], 1.31-4.44) and PTSD among girls (OR, 6.80; 95% CI, 2.16-21.58), and PTSD among boys (OR, 3.81; 95% CI, 1.06-13.73) but was not associated with general psychological difficulties (OR, 2.08; 95% CI, 0.86-5.02), anxiety (OR, 1.63; 95% CI, 0.77-3.45), or function impairment (OR, 1.34; 95% CI, 0.84-2.14). CONCLUSION In Nepal, former child soldiers display greater severity of mental health problems compared with children never conscripted by armed groups, and this difference remains for depression and PTSD (the latter especially among girls) even after controlling for trauma exposure.

Annual Research Review: Resilience and mental health in children and adolescents living in areas of armed conflict – a systematic review of findings in low‐ and middle‐income countries

BACKGROUND Researchers focused on mental health of conflict-affected children are increasingly interested in the concept of resilience. Knowledge on resilience may assist in developing interventions aimed at improving positive outcomes or reducing negative outcomes, termed promotive or protective interventions. METHODS We performed a systematic review of peer-reviewed qualitative and quantitative studies focused on resilience and mental health in children and adolescents affected by armed conflict in low- and middle-income countries. RESULTS Altogether 53 studies were identified: 15 qualitative and mixed methods studies and 38 quantitative, mostly cross-sectional studies focused on school-aged children and adolescents. Qualitative studies identified variation across socio-cultural settings of relevant resilience outcomes, and report contextually unique processes contributing to such outcomes. Quantitative studies focused on promotive and protective factors at different socio-ecological levels (individual, family-, peer-, school-, and community-levels). Generally, promotive and protective factors showed gender-, symptom-, and phase of conflict-specific effects on mental health outcomes. CONCLUSIONS Although limited by its predominantly cross-sectional nature and focus on protective outcomes, this body of knowledge supports a perspective of resilience as a complex dynamic process driven by time- and context-dependent variables, rather than the balance between risk- and protective factors with known impacts on mental health. Given the complexity of findings in this population, we conclude that resilience-focused interventions will need to be highly tailored to specific contexts, rather than the application of a universal model that may be expected to have similar effects on mental health across contexts.

Evaluation of a classroom-based psychosocial intervention in conflict-affected Nepal: a cluster randomized controlled trial

BACKGROUND In situations of ongoing violence, childhood psychosocial and mental health problems require care. However, resources and evidence for adequate interventions are scarce for children in low- and middle-income countries. This study evaluated a school-based psychosocial intervention in conflict-affected, rural Nepal. METHODS A cluster randomized controlled trial was used to evaluate changes on a range of indicators, including psychiatric symptoms (depression, anxiety, posttraumatic stress disorder), psychological difficulties, resilience indicators (hope, prosocial behavior) and function impairment. Children (n = 325) (mean age = 12.7, SD = 1.04, range 11-14 years) with elevated psychosocial distress were allocated to a treatment or waitlist group. RESULTS Comparisons of crude change scores showed significant between-group differences on several outcome indicators, with moderate effect sizes (Cohen d = .41 to .58). After correcting for nested variance within schools, no evidence for treatment effects was found on any outcome variable. Additional analyses showed gender effects for treatment on prosocial behavior (mean change difference: 2.70; 95% CI, .97 to 4.44), psychological difficulties (-2.19; 95% CI, -3.82 to -.56), and aggression (-4.42; 95% CI, -6.16 to -2.67). An age effect for treatment was found for hope (.90; 95% CI, -1.54 to -.26). CONCLUSIONS A school-based psychosocial intervention demonstrated moderate short-term beneficial effects for improving social-behavioral and resilience indicators among subgroups of children exposed to armed conflict. The intervention reduced psychological difficulties and aggression among boys, increased prosocial behavior among girls, and increased hope for older children. The intervention did not result in reduction of psychiatric symptoms.

Mental Health and Childhood Adversities: A Longitudinal Study in Kabul, Afghanistan

Objective To identify prospective predictors of mental health in Kabul, Afghanistan. Method Using stratified random-sampling in schools, mental health and life events for 11-to 16-year-old students and their caregivers were assessed. In 2007, 1 year after baseline, the retention rate was 64% (n = 115 boys, 119 girls, 234 adults) with no evidence of selection bias. Self- and caregiver-rated child mental health (Strengths and Difficulties Questionnaire), depressive (Depression Self-Rating Scale), and posttraumatic stress (Child Revised Impact of Events Scale) symptoms and caregiver mental health (Self-Report Questionnaire) were assessed. Lifetime trauma and past-year traumatic, stressful, and protective experiences were assessed. Results With the exception of posttraumatic stress, one-year trajectories for all mental health outcomes showed significant improvement (p < .001). Family violence had a striking impact on the Strengths and Difficulties Questionnaire data, raising caregiver-rated scores by 3.14 points (confidence interval [CI] 2.21–4.08) or half a standard deviation, and self-rated scores by 1.26 points (CI 0.50–2.03); past-year traumatic beatings independently raised self-rated scores by 1.85 points (CI 0.03–3.66). A major family conflict raised depression scores by 2.75 points (CI 0.89–4.61), two thirds of a standard deviation, whereas improved family life had protective effects. Posttraumatic stress symptom scores, however, were solely contingent on lifetime trauma, with more than three events raising scores by 5.38 points (CI 1.76–9.00). Conclusions Family violence predicted changes in mental health problems other than posttraumatic stress symptoms in a cohort that showed resilience to substantial socioeconomic and war-related stressors. The importance of prospectively identifying impacts of specific types of childhood adversities on mental health outcomes is highlighted to strengthen evidence on key modifiable factors for intervention in war-affected populations.

Interventions for children affected by war: an ecological perspective on psychosocial support and mental health care.

BackgroundChildren and adolescents exposed to armed conflict are at high risk of developing mental health problems. To date, a range of psychosocial approaches and clinical/psychiatric interventions has been used to address mental health needs in these groups. AimsTo provide an overview of peer-reviewed psychosocial and mental health interventions designed to address mental health needs of conflict-affected children, and to highlight areas in which policy and research need strengthening. MethodsWe used standard review methodology to identify interventions aimed at improving or treating mental health problems in conflict-affected youth. An ecological lens was used to organize studies according to the individual, family, peer/school, and community factors targeted by each intervention. Interventions were also evaluated for their orientation toward prevention, treatment, or maintenance, and for the strength of the scientific evidence of reported effects. ResultsOf 2305 studies returned from online searches of the literature and 21 sources identified through bibliography mining, 58 qualified for full review, with 40 peer-reviewed studies included in the final narrative synthesis. Overall, the peer-reviewed literature focused largely on school-based interventions. Very few family and community-based interventions have been empirically evaluated. Only two studies assessed multilevel or stepped-care packages. ConclusionsThe evidence base on effective and efficacious interventions for conflict-affected youth requires strengthening. Postconflict development agendas must be retooled to target the vulnerabilities characterizing conflict-affected youth, and these approaches must be collaborative across bodies responsible for the care of youth and families.

Social ecology of child soldiers: Child, family, and community determinants of mental health, psychosocial well-being, and reintegration in Nepal

This study employed a social ecology framework to evaluate psychosocial well-being in a cross-sectional sample of 142 former child soldiers in Nepal. Outcome measures included the Depression Self Rating Scale (DSRS), Child Posttraumatic Stress Disorder Symptom Scale (CPSS), and locally developed measures of functional impairment and reintegration. Hierarchical linear modeling was used to examine the contribution of factors at multiple levels. At the child level, traumatic exposures, especially torture, predicted poor outcomes, while education improved outcomes. At the family level, conflict-related death of a relative, physical abuse in the household, and loss of wealth during the conflict predicted poor outcomes. At the community level, living in high caste Hindu communities predicted lack of reintegration supports. Ultimately, social ecology is well suited to identify intervention foci across ecological levels based on community differences in vulnerability and protective factors.

Political violence and mental health: a multi-disciplinary review of the literature on Nepal.

Implementation of current international consensus guidelines regarding mental health and psychosocial support in emergencies requires the consideration of findings from both the medical and social sciences. This paper presents a multi-disciplinary review of reported findings regarding the relations between political violence, mental health and psychosocial wellbeing in Nepal. A systematic search of six databases resulted in the identification of 572 studies, of which 44 were included in the review. These studies investigated the influence of political violence on contextual variables that shape mental health and psychosocial wellbeing, and examined psychological distress and mental disorders in the context of political violence. The majority of studies addressed the mental health of Bhutanese refugees in Nepal and the impact of the Maoist Peoples War. Based upon these results from Nepal, we discuss a number of issues of concern to international researchers and practitioners and present policy and research recommendations. Specifically, we consider (a) the need for longitudinal multi-disciplinary research into protective and risk factors, including agency, of psychological distress and mental disorders in situations of political violence, (b) the continuing controversy regarding the PTSD construct, and (c) the lack of robust findings regarding the effectiveness of mental health and psychosocial support.

Mediators and moderators of a psychosocial intervention for children affected by political violence.

OBJECTIVE The authors examined moderators and mediators of a school-based psychosocial intervention for children affected by political violence, according to an ecological resilience theoretical framework. METHOD The authors examined data from a cluster randomized trial, involving children aged 8-13 in Central Sulawesi, Indonesia (treatment condition n = 182, waitlist control condition n = 221). Mediators (hope, coping, peer/emotional/play social support) and moderators (gender, age, family connectedness, household size, other forms of social support, exposure to political violence, and displacement) of treatment outcome on posttraumatic stress symptoms and function impairment were examined in parallel process latent growth curve models. RESULTS Compared with the waitlist group, those receiving treatment showed maintained hope, increased positive coping, maintained peer social support, and increased play social support. Of these putative mediators, only play social support was found to mediate treatment effects, such that increases in play social support were associated with smaller reductions in posttraumatic stress disorder (PTSD) symptoms. Furthermore, the authors identified a number of moderators: Girls showed larger treatment benefits on PTSD symptoms; girls, children in smaller households, and children receiving social support from adults outside the household showed larger treatment benefits on function impairment. CONCLUSIONS Findings provide limited evidence for an ecological resilience theoretical framework. On the basis of these findings, the authors recommend a stronger separation between universal prevention (e.g., resilience promotion through play) and selective/indicated prevention (e.g., interventions aimed at decreasing posttraumatic stress symptoms). Play-based interventions should be careful to exclude children with psychological distress. In addition, treatment effects may be augmented by selecting girls and socially vulnerable children.
