Sleep problems, ranging from mild sleep disturbance to debilitating insomnia, are among the most common health problems occurring in adults, with an estimated prevalence of 35% to 48% (Morin et al., 2009; Mai and Buyss 2008). Insomnia is a fairly common sleep disorder characterized by difficulty falling asleep, difficulty staying asleep, or waking up too early despite adequate sleep opportunity, recurring at least three times a week and accompanied by significant stress or distress during the day (Morin and Jarrin, 2013). ). According to the American guidelines for the treatment of chronic insomnia published in 2017, pharmacotherapy and non-pharmacological treatment are the two main treatment methods for sleep disorders ( Sateia et al., 2017 ).Mindfulness-based stress reduction (MBSR) is an important type of non-pharmacological mindfulness-based intervention that effectively relieves insomnia by decentering (Banno et al., 2019).Regarding the effect of mindfulness intervention in sleep disorders, Ong and Moore suggest that mindfulness can improve sleep by reducing both primary and secondary arousal (Ong and Moore, 2020).Therefore, this study aims to expand the existing investigations by examining whether mindfulness meditation (MBSR) is associated with changes in objectively measured polysomnographic (PSG) sleep profiles of patients with sleep disorders who applied to the Sleep EMG department of Muş State Hospital, and to examine the changes in PSG sleep in the context of a randomized controlled trial. It aims to determine the effect on quality of life by associating it with subjectively reported sleep and stress changes.

Neuondorf et al., (2015) reviewed 112 research studies of insomnia or sleep disturbance testing a variety of different mind-body interventions, including meditation, and found that although the evidence was heterogeneous, limited, and potentially biased, mind-body training was a treatment option for patients. It has been shown that it can be accepted as (Neuendorf et al., 2015). A recent systematic review and meta-analysis focused on identifying and evaluating the clinical significance of different mindfulness-based interventions (MBI) on sleep in individuals with anxiety and depression, showing significant effects on sleep problem improvement across all MBI programs (Chan et al. al., 2022) .Therefore, this study aims to expand the existing investigations by examining whether mindfulness meditation (MBSR) is associated with changes in objectively measured polysomnographic (PSG) sleep profiles of patients with sleep disorders who applied to the Sleep EMG department of Muş State Hospital, and to examine the changes in PSG sleep in the context of a randomized controlled trial.

Randomization Criteria In this study, individuals;

Control Group; It is planned to conduct a one-session (60-minute), unstructured, active participation-based group application (the week when the first session is applied to the intervention group) in which participants share their experiences with each other about stress and stressful experiences.

Intervention Group: Conscious Awareness Based Stress Reduction (BFTSA) intervention consists of seven sessions in total and is planned to be completed in a total of seven weeks, with one session per week and each session being 45 minutes. After the results of the patients who underwent PSG are determined according to the randomization criteria and receive certain points from the sleep scale, it is planned to call the patients by phone and explain the meaning and importance of the study, the applications to be performed in the study and its duration. It is planned to have an online individual interview with patients who agree to participate in this study.
