Description of intervention(s) / exposure
This project evaluates whether correspondence programs for depression, that focus on working with general practitioners to maintain physical or mental health, result in adoption of healthier lifestyles and consequently reduce the risk of relapse. Participants are assigned to one of two treatment conditions. The depression prevention condition involves monitoring triggers and early warning signs, increasing pleasurable events, planning for relapse prevention and building social support. The physical health condition involves increasing physical activitiy, addressing smoking and improving diet and oral health. In each condition participants receive four fortnightly and three monthly letters describing the program elements and how to apply them. After six months, participants switch conditions and receive the alternate treatment program.
