About this study
Official title: A Proof-of-Concept Study Evaluating a Theory-Based Motivational Letter to Increase Attendance to a One-Year Post-Cardiac Rehabilitation Risk Factor Check
The goal of this study is to see if a theory-based motivational letter can increase attendance at a one-year post-cardiac rehabilitation (CR) appointment in adults who have finished a CR program. The main question it aims to answer is:
- Can a theory-based motivational letter increase attendance at one-year follow-up appointments?
Researchers will compare participants who received the letter to those who received care as usual to see if there are any differences in attendance and risk factor management.
Participants will:
- Get a letter approximately 6 months before their one-year follow-up or care as usual
- Attend any appointments as usual
- Do routine health checks during their visits
- Conditions
- Cardiovascular Diseases (CVD)
- Being tested
- Theory-based motivational letter
- Keywords
- cardiac rehabilitation, attendance, motivational letter, health behaviours, theory of planned behaviour (TPB), health action process approach (HAPA), risk factors
- Medical subject headings
- Cardiovascular Diseases

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Attendance at one-year post-CR follow-up appointment (time frame: From enrollment to the one-year post-CR follow-up appointment). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Feb 2026.
