Sleep Quality, Stress Level and Heart Rate Variability of University Students

Study Overview
=================
Brief Summary
-----------------
Purpose: This study aims to determine the impact of mindfulness-based stress reduction programs on sleep quality, stress level and heart rate variability of university students Design: The study was planned as an experimental study with a randomized control group, using pre-test, post-test and follow-up test. Hypotheses: H1: The sleep quality level scores of the students in the intervention group participating in the mindfulness-based stress reduction initiative will increase compared to the students in the control group. H2: Students in the intervention group participating in the mindfulness-based stress reduction initiative will decrease their stress level level scores compared to the students in the control group. H3: The heart rate variability of the students in the intervention group participating in the mindfulness-based stress reduction initiative will be higher than the students in the control group. H4: The sleep quality level posttest and follow-up scores of the students in the intervention group participating in the mindfulness-based stress reduction initiative will increase compared to their pretest scores. H5: The stress level posttest and follow-up scores of the students in the intervention group participating in the mindfulness-based stress reduction initiative will increase according to their pretest scores. H6: The heart rate variability level posttest and follow-up scores of the students in the intervention group participating in the mindfulness-based stress reduction initiative will increase according to their pretest scores.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: MSQSLHRV<br>The group in which the mindfulness-based stress reduction intervention will be implemented. | Behavioral: Mindfulness Based Stress Reduction Intervention<br>* Mindfulness Based Stress Reduction intervention is a manualized course that includes meditation, relaxing movement, and breathing. A certified MBSR instructor will teach the courses in a group-based format for 90 minute sessions, once per week for eight weeks.<br>|
| No Intervention: Control<br>The group to which mindfulness-based stress reduction intervention will not be applied | |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Sleep Quality Level | The Pittsburgh Sleep Quality Index: The 18 items scored are divided into 7 component scores. Some ingredients consist of a single substance, while others are obtained by combining several substances. Each item is assessed on a scale between 0-3. These components are; subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbance, use of sleeping pills, daytime dysfunction. The sum of these seven component scores gives the overall index score. Your total score is between 0-21. A high total score indicates poor sleep quality. The index does not indicate the presence or prevalence of sleep disorders. | for 8 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Stress Level | Perceived Stress Scale is a scale consisting of 14 questions. Participants in the study evaluate each item on a 5-point Likert-type scale ranging from Never (0) to Very often (4). The Perceived Stress Scale includes 7 (items 4.5.6.7.9.10. and 13.) reverse scored statements. Total scale scores range from 0 to 56. An increase in the total score indicates an increase in the perceived stress level of the individual. | for 8 months | 
| Heart Rate Variability | CorSense HRV monitors were purchased from the Elite HRV company for use in the study. Readings will be collected through the Elite HRV app designed for mobile devices. RMSSD and LF/HF data will be received for each reading from the application. According to the Elite HRV website, the platform includes RMSSD calculations for the R-R range recorded by industry standards and defines 0.04-0.15 Hz waves as LF and 0.15-0.40 Hz waves as HF. | for 8 months |
