Peace and war: trajectories of posttraumatic stress disorder symptoms before, during, and after military deployment in Afghanistan.
Repository Usage Stats
In the study reported here, we examined posttraumatic stress disorder (PTSD) symptoms in 746 Danish soldiers measured on five occasions before, during, and after deployment to Afghanistan. Using latent class growth analysis, we identified six trajectories of change in PTSD symptoms. Two resilient trajectories had low levels across all five times, and a new-onset trajectory started low and showed a marked increase of PTSD symptoms. Three temporary-benefit trajectories, not previously described in the literature, showed decreases in PTSD symptoms during (or immediately after) deployment, followed by increases after return from deployment. Predeployment emotional problems and predeployment traumas, especially childhood adversities, were predictors for inclusion in the nonresilient trajectories, whereas deployment-related stress was not. These findings challenge standard views of PTSD in two ways. First, they show that factors other than immediately preceding stressors are critical for PTSD development, with childhood adversities being central. Second, they demonstrate that the development of PTSD symptoms shows heterogeneity, which indicates the need for multiple measurements to understand PTSD and identify people in need of treatment.

Research in my lab concerns the means by which adolescents and emerging adults manage pursuit of their goals through self-regulation. We take a broad view of self-regulation, accounting for the separate and interactive influences of personality, environment (e.g., home, school, neighborhood), cognition and emotion, and social influences on the many facets of goal management. Although we occasionally study these influences in controlled laboratory experiments, our preference is to study the pu
