An interventional study of Sleep Hygiene Education in Cardiovascular Disease and Sleep Hygiene, sponsored by Near East University, Turkey. Not yet recruiting. Per ClinicalTrials.gov, last updated 2025-08-24.
Sponsored by Near East University, Turkey · Not applicable, Interventional, and Supportive care
This clinical trial aims to find out if sleep hygiene education helps people with cardiovascular disease manage their illness better and improve their sleep quality.
Participants will be randomly assigned to two groups. One group will receive sleep hygiene education through a 30-minute presentation and twice-daily reminder messages for four weeks. The other group will receive usual care without education.
Before and after the four-week period, all participants will complete questionnaires about their sleep habits, sleep quality, and disease management.
The study hopes to show that sleep hygiene education can improve participants' sleep and help them manage their disease symptoms better, leading to a better quality of life.
The trial will take place at Near East University Hospital's Cardiology Department from June to December 2025.

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Behavioral: Sleep Hygiene Education
This intervention consists of a nurse-led sleep hygiene education program delivered through a 30-minute PowerPoint presentation. Participants in the intervention group will also receive twice-daily reminder messages via WhatsApp for four weeks to reinforce healthy sleep habits. The program aims to improve sleep quality and disease management in individuals with cardiovascular disease. After the study, the educational materials will also be shared with the control group.
Improvement in Sleep Quality
This outcome measures the change in participants' sleep quality after the 4-week sleep hygiene education program. Sleep quality will be assessed using the Pittsburgh Sleep Quality Index (PSQI). The PSQI total score ranges from 0 to 21, where higher scores indicate worse sleep quality and lower scores indicate better sleep quality. Data will be collected at baseline and after completion of the intervention.
Time frame: 5 weeks (4 weeks intervention + final assessment in week 5)
Improvement in Disease Management
This outcome measures the change in participants' disease self-management ability after the 4-week sleep hygiene education program. Disease management will be assessed using the Chronic Disease Self-Management Scale (CDSMS). The CDSMS total score ranges from 0 to 100, with higher scores indicating better self-management and lower scores indicating poorer self-management. Data will be collected at baseline and after completion of the intervention.
Time frame: 5 weeks (4 weeks intervention + final assessment in week 5)

Start is estimated for Sep 2025; primary completion for Oct 2025, 1 month later.
Of 1,077 non-industry interventional studies with no phase under Cardiovascular Diseases, half reached primary completion within 26 months of starting (the median), counting those still running; a quarter within 12 and three quarters within 48. This study's planned 1 month is below that.
Counting every sponsor, half of 1,216 studies reached it within 26 months; a quarter within 12 and three quarters within 49.
Cardiovascular Diseases covers many different conditions, not one, so the studies compared here vary widely. Read these figures as a rough guide.
