The primary objective of this research is to examine two brief interventions for depression, Behavioral Activation (BA), and Problem Solving Therapy (PST), to investigate whether exposure to adverse childhood experiences influences change in the hypothesized target treatment mechanisms linked to each intervention. Research suggests that the treatment targets of BA (reward processing) may be well-matched for youths exposed to childhood adversity, due to disruptions in reward that are linked with adversity exposure. The investigators will examine the effects of youths' adverse life experiences on change in reward-related treatment targets in BA, and compare this to change in the treatment targets of PST, executive functioning processes. The first aim is to investigate the effects of childhood adversity on change in target treatment mechanisms in BA and PST. The second aim is to test whether changes in reward processes is specific to BA, and not PST, among youths exposed to adversity. The third aim is to test the match of BA for depression among youths exposed to adversity, by examining whether BA results in greater reductions in depression symptoms among youths with greater adversity exposure. The investigators will also test whether greater change in reward in associated with greater depression symptom reductions in BA, and not PST.
