Official title

Online Positive Emotion Skills Intervention for Symptoms of Depression - Pilot Feasibility Trial

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Major depressive disorder affects over 120 million people worldwide. Only 50% of Americans with depression receive adequate treatment, and one-third of those receiving treatment do not benefit. In this pilot project investigators will bring together two approaches that have the promise to reach large numbers of depression sufferers: a skills-based intervention for increasing positive affect and experiences in depressed individuals, delivered in an inexpensive self-paced mobile format. The study will make use of smartphone technology to improve conventional outcome measurement via in-the-moment emotion sampling and mobile assessment of heart rate variability, a predictor of cardiac health that may mediate some of the health effects of depression. The aims are: 1) Retool the existing web-based positive emotion intervention for use on smartphones, with innovative exercises that help participants bring the skills they are learning into real- life situations; 2) Measure heart rate variability and emotions using existing smartphone software; and 3) Perform a randomized pilot trial of the mobile intervention on individuals with clinical depression recruited online.
