Background

Depression is the largest contributor to disability among all Mental and substance abuse disorders, not only amounting to serious personal difficulties, but also social, economic and societal costs. Digital interventions for depression, such as, internet-delivered Cognitive Behavioral Therapy (iCBT) are a well-established and evidence-based option for the treatment of depression. Monitoring of daily activities and experiences, involved in behavioral activation, is a core tenet of CBT for depression. Insights from monitoring help both patients and therapists identify the patterns between a patient’s behavior and their mood in order to improve outcomes. For example, sleep problems can often co-occur with depression while moderate levels of physical exercise can improve depression symptoms.
