Intergenerational Study of War-Affected Youth

The Intergenerational Study of War-Affected Youth (ISWAY) entails a fifth wave of data collection in a 22-year study of war-affected youth in Sierra Leone (LSWAY), the first of its kind in Sub-Saharan Africa. LSWAY findings drawn from four waves of data collection (T1:2002, T2: 2004, T3: 2008, T4:2016/17) indicate that a healthy transition to adulthood among war-affected youth was linked to engagement in prosocial behavior and community involvement, while problems with hostility, poor emotion regulation, and social withdrawal created barriers to achieving healthy and productive lives. Community stigma and poor family acceptance compounded these barriers. Preliminary analyses of offspring of war-affected youth-first enrolled at T4-indicated that harsh paternal parenting was associated with offspring poor mental health and maternal parenting (harsh and warm) predicted offspring disruptions in emotion regulation and mental health. The investigators theorize such associations are linked to biological mechanisms, but research to date has been limited to cross-sectional data on the health and mental health of biological offspring. ISWAY will examine how social and biobehavioral mechanisms operate among war-affected parents to shape parenting and the mental health of offspring. The study's guiding framework blends a biobehavioral and ecological model of risk and resilience with the Stress Adjustment Paradigm.The Multisystemic Model of Child Development holds that both behavioral and biological mechanisms are influenced by risk and protective factors at different levels of the social ecology and that exposure to trauma may lead to disruptions in individual stress reactivity and emotion regulation. The Stress-Adjustment Paradigm posits that traumatic life events lead to individual outcomes that are shaped by risk and protective processes across the social ecology. Taken together, these theories propose that both past trauma and current social stressors (e.g., underemployment, stigma) have implications for understanding the mechanisms linking past parental trauma to parent-child interactions and the mental health of subsequent generations. Adult stress reactivity, including ANS reactivity, may manifest in similar ways among offspring. Biological markers of inflammation and telomere length may also be linked in war-affected parents and their offspring. An integrated model suggests that several important protective processes and resources may operate to mitigate these intergenerational disruptions such as social support and access to other attachment figures in the household who have strong self-regulation. Helping parents who have experienced severe trauma build self-regulation skills and extending social support networks may be critical components of preventive interventions. ISWAY entails an enriched follow-up of the parents and their offspring focusing on the RDoC-related constructs that may underlie self-regulation (negative/positive valence systems, arousal systems, social processes). Collecting and analyzing both behavioral and biological/physiological data will deepen understanding of mechanisms that may contribute to increased risk of mental health difficulties in offspring. This will be amplified by an exploration of modifiable risk and protective factors across the social ecology (individual, family, and community levels) to prioritize as intervention targets for addressing intergenerational risks to the mental health of offspring of war-affected parents.
