Behavioral Study to Predict the Efficacy of a Self-Help Tool

The study aims to examine whether the investigators can predict, on the level of individual participants who have symptoms of depression, who will benefit more from self-help tools based on principles of behavioral activation vs. cognitive restructuring, in terms of a greater decrease of self-reported symptoms. The investigators use a combination of self-reported clinical information and behavior on learning and decision-making tasks to predict change in symptom scores.
