What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

• Sociodemographic Data FormOther

  After inquiring about participants' sociodemographic characteristics, such as name, contact information, age, gender, marital status, education level, income, and place of residence, measurements of height, weight, and waist circumference will be obtained. Then, participants' CVD, psychiatric and other medical conditions, CVD risk factors, health history, and medications they are using will be queried. This information will be recorded in the sociodemographic data form. The sociodemographic data form has been prepared by the researchers.

• Short Form Health SurveyOther

  SF-36 is a self-assessment scale and can be completed in five minutes. SF-36 can evaluate both the negative and positive aspects of health. The scale consists of 36 items which are used to assess different health dimensions in 8 subscales: Physical functioning (10 items), social functioning (2 items), role limitations due to physical problems (4 items), role limitations due to emotional problems (3 items), mental health (5 items), energy/vitality (4 items), pain (2 items), and general health perception (5 items).

• Hospital Anxiety and Depression ScaleOther

  The HADS was designed in 1983 to identify anxiety and depression in individuals with physical illnesses. The HADS is a self-reported scale consisting of seven items each for the anxiety and depression subscales. Each item is scored from 0 to 3, and the total score for the anxiety and depression subscales is 21 points. The overall HADS score is obtained by summing the points from both subscales. A total subscale score between 0-7 indicates a normal test result, 8-10 indicates mild anxiety or depression, 11-15 indicates moderate anxiety or depression, and 16-21 indicates severe anxiety or depression. Higher scores represent higher levels of anxiety or depression, and the total HADS score reflects an overall measure of psychological distress. The survey can be completed in 2-5 minutes.

• Illness Intrusiveness Ratings ScaleOther

  The IIRS is an easy-to-administer scale designed to predict the psychosocial impact of chronic illness and to document and compare the effectiveness of therapeutic interventions. It consists of 13 questions which are completed by the patient. The scale measures how the limitations imposed by chronic and life-threatening diseases hinder participation in regular activities across 13 important aspects of life: Health, diet, work, active recreation (sports), passive recreation (reading, listening to music), finances, relationships with partners, sexual life, family relationships, other social relationships, self-expression/development, religious expression, and community and civic participation.

• Cardiac Depression ScaleOther

  CDS was designed to identify depression in individuals with CVDs. It consists of 26 items across 7 subscales. The subscales address issues such as sleep, uncertainty, mood, hopelessness, immobility, anhedonia, and cognition. The CDS is rated on a 7-point Likert scale, with seven items being reverse-coded. Based on patient feedback and clinical experience, two short forms were developed, each consisting of five questions. Both short forms showed good consistency with the original CDS. The first short form includes questions from the original CDS numbered 12, 24, 21, 10, and 9. The second short form includes questions from the original CDS numbered 12, 4, 25, 21, and 7.

What is being measured

The primary outcome is the main question the study is designed to answer.

1. Depression

   The primary outcome measure in the study is depression, as determined by the Cardiac Depression Scale (CDS), while other scales and participant demographic data will be considered as independent variables. CDS scores range from 26 to 182, with higher scores indicating more severe depressive symptoms. A score of 95 or higher on the CDS can detect major depression in individuals with CVD with 85% specificity and 97% sensitivity.

   Measured: Baseline
