abstract = {ObjectiveTo investigate the influence of stress on insomnia among plateau soldiers, and explore the mediating role of parent-child alienation and the moderating role of emotion regulation strategies in this relationship.MethodsA cross-sectional study design was adopted in this study. Our Self-designed General Information Questionnaire, Plateau Soldiers Stressor Scale, Insomnia Severity Index, Inventory of Alienation towards Parents, and Emotion Regulation Scale were employed to survey 2 065 plateau soldiers at an average altitude of 4 200 m. With aid of SPSS 26.0 statistics, descriptive analysis, correlation analysis and regression analysis were applied to analyze stress status, parent-child alienation, insomnia and emotion regulation in the participants, and then a structural equation model was established.Results① The scores of stress, parent-child alienation and insomnia were significantly higher in the participants who were older, well educated (P < 0.01) and were or had been in a marital relationship (married, divorced, or widowed)(P < 0.001) than those without above conditions.② Significant pairwise positive correlations were observed among stress, parent-child alienation, insomnia, cognitive reappraisal, and expressive suppression (r=0.08~0.61, P < 0.001).③ Stress and expressive suppression could positively predict parent-child alienation (β=0.14~0.43, P < 0.001), and stress, parent-child alienation and expressive suppression could positively predict insomnia (β=0.04~0.25, P < 0.01). Cognitive reappraisal could not significantly predict parent-child alienation or insomnia.④Parent-child alienation towards parents partially mediated the relationship between stress and insomnia, with a mediation effect accounting for 7.29% of the total effect.⑤ Expressive suppression moderated the impact of stress on insomnia (β=-0.01, P < 0.001), and the higher expressive suppression level mitigated the adverse effect of stress on insomnia when compared with the lower expressive suppression level.ConclusionFor plateau soldiers, stress significantly predicts insomnia, with parent-child alienation playing a mediating role. Furthermore, a higher level of expressive suppression can effectively buffer the influence of stress on insomnia.}
