What this Trial Is About
The effects of a monitoring intervention as an add-on to face-to-face Cognitive Behavioral Therapy (CBT) for depression are assessed in this randomised trial. Monitoring consists of Ecological Momentary Assessment (EMA) of symptoms and inter-session processes via mobile phones. Twenty sessions of face-to-face CBT + EMA are compared to twenty sessions of face-to-face CBT (treatment as usual, TAU). 84 patients with mild to moderate depression will be randomised to CBT + EMA or to TAU.
