The Effectiveness of Training Based on Metacognition on Sleep Quality and Insomnia Symptoms in Nurses

Introduction: Every person’s sleep is related to their health and due to their type of occupation; nurses are likely to be more exposed to low-quality sleep. The aim of this study is to investigate the effectiveness of training based on metacognition on sleep quality and insomnia symptoms in nurses at Shiraz University of Medical Sciences hospital. Methods: The present study is a quasi-experimental one with a pre-test, post-test and, follow-up group design. A total of 36 nurses of shiraz university of medical science hospital were selected based on inclusion and exclusion criteria in 1399 and placed randomly into experimental and control groups as each one holds 18 subjects. The experimental group went under 12 sessions of 75 minutes of metacognition training. Participants were assessed first with a demographic questionnaire and then a Pittsburgh sleep quality questionnaire in three stages. Data analysis was performed using SPSS software version 23. Results: Sleep quality’s mean± standard deviation scores before the training in the experimentaland control group are 13.11­±1.80 and 11.72­±1.93 respectively, which changed into 8.44­±2.35 and 12.28­±2.27 after the intervention in the post-tests and were 7.72±1.56 and 11.78­±2.21 in the follow-ups. The result of frequent variance analysis shows that the mean score of sleep quality and its components including mental quality of sleep, delay in falling sleep, sleep duration and, sleep efficiency in the experimental group is more significant than in the control group as the P<0.001 and were consistent until the follow-ups. Conclusion: The results of this study show that metacognition training for nurses can be a proper method to improve sleep quality through their effect on sleep components including mental sleep quality, daily dysfunction, delay in falling sleep and, sleep efficiency.
