Effects of mindful attention awareness on sleep quality of soldiers stationed in plateau areas: Chain-mediated effect of burnout and occupational stress

BackgroundSleep quality is one of the important factors affecting soldiers’ task performance. ObjectiveTo explore the effects of mindful attention awareness, burnout, and occupational stress on sleep quality among soldiers in plateau areas. MethodsA total of 1090 soldiers were selected from four units in plateau areas by cluster sampling method and were asked to participate a cross-sectional questionnaire survey using the Pittsburgh Sleep Quality Index (PQSI), Occupational Stress Inventory (OSI), Maslach Burnout Inventory-General Survey (MBI-GS), and Mindful Attention Awareness Scale (MAAS). Correlation analysis, regression analysis, and mediated effect test were conducted for the study. ResultsOf the 1090 soldiers recruited, 1082 soldiers returned valid questionnaires, and the valid recovery rate was 99.26%. The median (P25, P75) score of PSQI was 4.00 (2.00,7.00), the median score of OSI was 26.00 (17.00, 34.00), the median score of MBI-GS was 3.53 (3.13, 4.00), and the median score of MAAS was 71.00 (59.00, 82.00). The burnout and mindful attention awareness levels varied among military personnel of different age groups (P
