Abstract:
Objective:To investigate the symptom detection rate and stability of anxiety and sleep quality in police officers,as well as the time-related effect of anxiety on sleep quality.Methods:The Self-Rating Anxiety Scale(SAS)and Pittsburgh Sleep Quality Index(PSQI)were used to track the anxiety and sleep quality of 564 po-lice officers twice for a year.SAS standard score ≥50 and PSQI total score＞7 were the detection criteria for anxi-ety symptoms and sleep disorders,respectively.x2 test was used to compare the differences of detection rate and the proportion of people in different symptom conversion groups.Structural equation model was used to analyze the time-related effect of anxiety on sleep quality.Results:The detection rates of anxiety symptoms and sleep disorder-swere higher in the police officers than in other studies(Ps＜0.001).The proportion of police officers with and without anxiety symptoms and sleep disorders was higher than that of the other two groupswith changes before and after(Ps＜0.05).Baseline anxiety positively predicted baseline sleep quality index(β=0.26,P＜0.001),and anx-iety after 1 year positively predicted sleep quality index after 1 year(β=0.19,P＜0.001).Baseline anxiety posi-tively predicted the sleep quality index after 1 year(β=0.06,P＜0.01).Conclusion:It shows that the stability of anxiety and sleep quality in police officers is relatively higher,and there is a high correlation between anxiety and sleep quality.
