Abstract

BACKGROUND:

Life stressors and personal and social resources are associated with depression in the short-term, but little is known about their associations with the long-term course of depression. The current paper presents results of a 23-year study of community adults who were receiving treatment for depression at baseline (N=382).

METHODS:

Semi-parametric group-based modeling was used to identify depression trajectories and determine baseline predictors of belonging to each trajectory group.

RESULTS:

There were three distinct courses of depression: high severity at baseline with slow decline, moderate severity at baseline with rapid decline, and low severity at baseline with rapid decline. At baseline, individuals in the high-severity group had less education than those in the moderate-severity group, and more medical conditions than those in the moderate- and low-severity groups. Individuals in the high- and moderate-severity groups evidenced less psychological flexibility, and relied more on avoidance coping than individuals in the low-severity group.

LIMITATIONS:

Results are limited by use of self-report and lack of information about depression status and life events in the periods between follow-ups.

CONCLUSIONS:

These results assist in identifying groups at high risk for a long-term course of depression, and will help in selecting appropriate interventions that target depression severity, coping skills and management of stressors.
