Brief summary
The overall aim and primary objective is to evaluate the effects on level of depression and anxiety of an Internet-based CBT-program in depressed and/or anxious patients after a myocardial infarction (MI).
Detailed description
Major or minor depressive disorders and anxiety disorders are present in many patients with cardiovascular disease (CVD) and are associated with adverse cardiovascular outcomes, even after controlling for other risk factors. 500 patients with symptoms of anxiety and/or depression after MI will be randomized either to a 14 week Internet-based CBT-program or to treatment as usual (TAU) which is the control condition. A reference group of 250 participants without depressive or anxiety symptoms will also be studied during TAU. Data will be collected before, after and 7 months after treatment. Anxiety and depression according to ratings on the Hospital Anxiety and Depression Scale (HADS) are the primary outcome measures.
Interventions
The participants read texts and do weekly homework assignments instructed from an Internet page. Additional resources like discussion forum, pictures, animations, videos and sounds will be a part of the treatment program. A psychologist will communicate with the participants through internal text-messages. The therapist will devote about 10 minutes to each participant each week via the Internet. The content of the intervention will be standard components from CBT, for example relaxation training, behavioral activation, exposure for fear related stimuli, cognitive restructuring, behavioral sleep treatment etc.
