Sleep Hygiene Education in Individuals With Cardiovascular Disease: Effects on Sleep Quality and Disease Management

N/ANot Yet RecruitingNCT07135921

Near East University, Turkey100 enrolled

Overview

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.

Outcomes

Primary Outcomes

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)

Secondary Outcomes

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)
