Plain English Summary

Background and study aims
Rehabilitation programmes run in hospitals can improve the quality of life of patients with heart disease. However, most patients do not participate in these programmes, while those who do participate do not complete the programme. A different approach to deliver the cardiac rehabilitation programme should be considered to improve patients' recovery. The aim of this study is to develop and examine the effectiveness of a home-based self-help psychoeducation programme on the quality of life, stress level, anxiety and depression symptoms, cardiac risk factors, and health service use of outpatients with heart disease.

Who can participate?
Adult outpatients of the participating hospital who have been diagnosed with coronary heart disease will be recruited in this study.

What does the study involve?
Once the patients have been enrolled into the study, they will be randomly allocated to either a home-based self-help psychoeducation programme group or another group without this programme. Study participants in both groups will be given the same questionnaires three times during the four-month study period. The research assistant will meet the study participants to give these questionnaires. At the end, participants who underwent the home-based self-help psychoeducation programme will be invited for individual face-to-face interviews.

What are the possible benefits and risks of participating?
There may be several benefits for the participants who receive the home-based self-help psychoeducation programme. These include a more positive perception of quality of life, lower stress levels, lesser symptoms of anxiety and depression, greater self-efficacy and a decrease of cardiac risk factors. There are no foreseeable risks for study participants.

Where is the study run from?
This study is run from the National University Heart Centre based in the National University Hospital, Singapore.

When is the study starting and how long is it expected to run for?
The recruitment is planned to start in January 2015 and end in December 2015.

Who is funding the study?
Ministry of Education (Singapore) will be funding this study.

Study information

Scientific title

A randomized controlled trial of the effectiveness of a self-help psychoeducation programme on outcomes of outpatients with coronary heart disease


Study hypothesis

When compared with study participants who are randomised into the group without the self-help psychoeducation programme, study participants in the group with the self-help psychoeducation programme will report a more positive perceived health-related quality of life, lower stress levels, lesser anxiety and depression symptoms, greater self-efficacy, lesser cardiac risk factors (i.e. levels of lipids, body mass index, blood pressure, and tobacco use) and also lower reported use of health services (e.g. cardiac-related hospital re-admission).

Coronary Heart Disease


Participants are randomised to two groups:

1. Intervention group: the intervention used in this study is the the self-help psychoeducation programme, which includes an education booklet, an accompanying DVD and an education session conducted by a member of the research team.
2. Control group: will not receive any additional intervention

All study participants will continue to receive their usual care from the hospital during their participation in this study.

Primary outcome measure

1. The cardiac risk factors (i.e. levels of lipids, body mass index, blood pressure, and tobacco use) will be recorded by a form designed by the research team
2. The amount of health service use (e.g. cardiac-related hospital re-admission) will be recorded by a form designed by the research team
3. Health-related Quality of Life (HRQoL) will be assessed using the 12-item Short Form Health Survey (SF-12v2). The SF-12 is a shorter version of the SF-36v2 (Ware, Kosinski & Keller, 1996).
4. The Perceived Stress Scale (PSS) measures the perception of stress of an individual (Cohen, Kamarck & Mermelstein, 1983)
5. Hospital Anxiety and Depression Scale (HADS) assesses for the presence of anxiety or depression in physically ill patients (Zigmond & Snaith 1983)
6. Self-efficacy will be assessed by the General Self-efficacy Scale, which measures the competency to manage challenging events (Schwarzer & Jerusalem, 1995)

The measures will be administered at baseline, the 4th week from baseline and the 12th week from baseline.

Secondary outcome measures

A process evaluation which utilises a qualitative approach using in-depth focused, individual face-to-face interviews will be used to measure the suitability, strengths and weaknesses of the self-help psychoeducation programme at baseline, the 4th week from baseline and the 12th week from baseline.
