Symptoms of depression, such as persistent sadness, problems sleeping, and inability to feel pleasure, interfere with the daily lives of more than 20 million Americans. Previous research indicates that telephone care management systems improve the quality and outcomes of depression care, but are too expensive to be used widely. Using secure messaging over e-mail would be more cost effective than telephone care. This study will examine whether a secure messaging care management program would be feasible, based on whether participants are willing to sign up for and continue with the program, and whether the program has a positive effect on those participants enrolled in the program.
