EHealth Intervention to Manage Depression and Anxiety in Patients with Ischemic Heart Disease

The 12-week intervention will consist of 9 modules and 2 optional modules that will be delivered to patients in the active intervention via a platform or app. Psychologists will provide asynchronous guidance via the platform. Motivational interviewing will be used during the intervention to prevent dropout. The psychologist may contact patients via telephone during the intervention if needed. All patients will have access to the intervention up to 6 months' post intervention so that they can revisit the material and reuse it on a need-to-basis. Patients will be recommended to use this option and to note specific time points in their agenda where they will access the intervention. A brief purpose-designed interview protocol that includes elements from the SCAN interview will be carried out by psychologists trained in conducting the interview.
