目的:探讨正念对精神科护士压力知觉的影响及心理弹性在其中的中介效应。方法:以北京市某三甲精神病专科医院的427名精神科护士为研究对象，采用五因素正念量表(five-facet mindfulness questionnaire，FFMQ)、压力知觉量表中文版(Chinese-version perceived stress scale，CPSS)及心理弹性量表(Connor-Davidson resilience scale，CD-RISC)进行测评。采用SPSS 24.0进行Pearson相关分析、多元逐步回归分析，使用AMOS 24.0进行中介效应检验。结果:精神科护士压力知觉总得分为(37.89±7.16)分，其中压力较大者占66.74%，压力过大者占20.84%。压力知觉与正念水平[(123.69±10.82)分]、心理弹性[(85.40±17.87)分]均呈负相关(n r＝-0.65，-0.67; n P<0.01)，正念水平与心理弹性呈显著正相关(n r＝0.50，n P<0.01)。正念水平对压力知觉的直接效应为-0.15，间接效应为-0.34，总效应为-0.49。n 结论:心理弹性在精神科护士正念水平和压力知觉之间起到部分中介作用。“,”Objective:To explore the influence of mindfulness on perceived stress in psychiatric nurses and the mediating effect of resilience.Methods:A total of 427 psychiatric nurses from a psychiatric hospital in Beijing were selected.Five-facet mindfulness questionnaire(FFMQ), Chinese-version perceived stress scale (CPSS) and Connor-Davidson resilience scale (CD-RISC) were used in this survey.Pearson correlation analysis and multiple stepwise regression analysis were performed using SPSS 24.0.And mediating effect was performed using AMOS 24.0.Results:The total score of psychiatric nurses' perceived stress was (37.89±7.16). Among all psychiatric nurses, 66.74% were under high pressure and 20.84% were under great pressure.The perceived stress was negatively correlated with mindfulness(123.69±10.82,n r=-0.65, n P<0.01) and resilience(85.40±17.87,n r=-0.67, n P<0.01), and mindfulness was positively correlated with resilience (n r=0.50, n P<0.01). The direct effect of mindfulness on perceived stress was -0.15, the indirect effect was -0.34, and the total effect was -0.49.n Conclusion:Resilience plays a partial mediating role between mindfulness and perceived stress psychiatric nurses.
