Trajectories of depression symptoms during the process of deployment in military couples.

Informed by life course theory, we estimated depression symptom trajectories for couples throughout a deployment cycle using data from a longitudinal study of National Guard couples (= 339). One-third of couples served as a comparison group by participating in data collection after their deployments were canceled. We proposed that 1) service members and partners would display multiple trajectories of depression symptoms that differ as a function of role (i.e., service member or at-home partner) and exposure to deployment; 2) trajectory patterns would be associated with indicators of human capital; 3) service members' and partners' depression symptoms would be linked to each other. We found that depressive symptom trajectories varied by exposure to deployment and role, and that higher levels of human capital were mostly associated with lower depressive symptoms, although we did not find support for partner interdependence. Results were considered in the context of life course theory and emotional cycles of deployment.
