Research paper thumbnail of Unpacking Trauma Exposure Risk Factors and Differential Pathways of Influence: Predicting Postwar Mental Distress in Bosnian Adolescents: Unpacking Trauma Exposure Risk Factors

Child Development, 2010

Traditional methods for constructing war exposure measures are poorly suited to “unpack” differential relations between specific types of exposure and specific outcomes. This study of 881 Bosnian adolescents compared both common factor–effect indicator (using exploratory factor analysis) versus composite causal–indicator methods for “unpacking” dimensions of war exposure and their respective paths to postwar adjustment outcomes. The composite method better supported theory building and most intervention applications, showing how multitiered interventions can enhance treatment effectiveness and efficiency in war settings. Used together, the methods may unpack the elements and differential effects of “caravans” of risk and promotive factors that co-occur across development.

Research paper thumbnail of The Risks, Benefits, and Ethics of Trauma-Focused Research Participation

Ethics & Behavior, 2010

Do individuals who participate in trauma-focused research risk experiencing lasting negative effects from participation? What are the potential benefits that may be gleaned from participation in this work? How can trauma research studies be designed ethically, minimizing the risk to participants? The following review seeks to answer these questions. This review indicates that most studies in this area have found that only a minority of participants experience distress when participating in trauma-focused research. Furthermore, these negative feelings tend to dissipate quickly over time, with the majority of participants self-appraising their participation as positive, rewarding, and beneficial to society. Design characteristics that may serve to minimize participants' risk of experiencing distress are discussed, as well as implications for public policy and future research.
