Registration Number: NCT02778074

Lead Sponsor: University Hospital, Linkoeping

Brief Summary: Purpose and aims Tailored internet-based cognitive behavioural therapy (I-CBT) is a new innovative and person-centred method that is promising that may be used to decrease depression in patients with cardiovascular disease (CVD). In patients with CVD, depressive symptoms is a common co-morbidity leading to decreased wellbeing, and increased morbidity and mortality. Depressive symptoms are both underdiagnosed and undertreated in CVD patients. Earlier studies have demonstrated the efficiency of cognitive behavioural therapy (CBT) for many psychiatric conditions, but few studies have evaluated CBT in patients with CVD.

The overall purpose of this study is to evaluate the effects of the tailored I-CBT program on reducing depressive symptoms and other patient reported outcomes in patients with cardiovascular disease (CVD) and to explore factors related to implementation of the I-CBT program in clinical cardiac care.

The primary aim:

-To evaluate the effects of the tailored I-CBT depression program on depressive symptoms.

Secondary aims:

* To evaluate effects on quality of life´, sleep and anxiety

* To evaluate factors that can influence the I-CBT programs effect on depressive symptoms.

* To gain knowledge about the I-CBT program, as perceived by patients and health care professionals.

* To explore facilitators and barriers to the implementation of the I-CBT program in clinical practice from the perspectives of patients, health care professionals and policymakers.

Detailed Description: Power calculation: Effect size=0.5, alpha=0.05 (Z=1.96), Power 0.80 (Z -0.84) = 122 participants. Due to drop-outs or deaths the size of the study population for the RCT study was decided to n=140.

Arm && Interventions

Group	Intervention	Description
Moderated discussion forum	Moderated Discussion Forum	In this arm the participants are allocated to a non mandatory discussion forum for nine weeks. Evert week will participants discuss issues regarding their CVD. Themes discussed are suggested by the study team, and a new theme is added every week. A moderator from the study group act as a supervisor and checks that issues discussed are ok. After the nine week discussion forum the participants are offered the nine week CBT program.
Internet Cognitive Behavioural Therapy	Internet cognitive behavioural therapy	Participants will perform a nine-week tailored I-CBT program developed to fit CVD patients. The program consists of psychoeducation, relaxation, problem-solving and behavioral activation.

Primary Outcome Measures

Name	Time	Method
Depressive Symptoms Collected With the Patient Health Questionnaire-9 (PHQ-9)	Score at 9 weeks follow-up	The PHQ-9 is a nine-item instrument for measurement of depressive symptoms during the last two weeks. Each item is answered on a four graded scale where zero represents that the item do not affect the person and numbers one to three represents that the item affects the person several days to almost every day. The answers are summed to a total sum score, range 0-27, with higher numbers representing higher level of depressive symptoms. A cut off \>5 represents minor depression and a cut off \>10 represents major depression
