摘要： 目的探讨不孕女性患者的知觉压力在正念水平与心理困扰之间的中介作用。方法采用简易心理状况调查表(K10)、正念注意觉知量表(MAAS)和知觉压力量表(PSS-10)对不孕女性进行调查。运用结构方程和Bootstrap程序进行中介效应的检验。结果 79.6%的不孕女性存在心理困扰;Spearman秩相关分析表明,正念水平与知觉压力(r_s=-0.529, P<0.001)和心理困扰(r_s=-0.600, P<0.001)呈中度负相关,知觉压力与心理困扰(r_s=0.691, P<0.001)呈中度正相关;结构方程模型显示,正念水平对知觉压力(β=-0.67, P<0.001)与心理困扰(β=-0.31, P=0.007)有显著的直接效应;知觉压力对心理困扰(β=0.64, P<0.001)也有显著的直接效应;Bootstrap检验表明知觉压力在正念水平与心理困扰之间起到中介作用(95%CI: -0.628~-0.299, P<0.001),中介效应占到总效应的58.1%。结论不孕女性患者的心理困扰较普遍,知觉压力的中介作用为正念水平与心理困扰关系的探讨提供了可能的机制。

Abstract: Objective To explore the mediating effect of perceived stress on the relationship between mindfulness level and psychological distress in infertile women. Methods The 10-item Kessler Psychological Distress Scale(K10), Mindful Attention Awareness Scale(MAAS), and 10-item Perceived Stress Scale(PSS-10)were adopted to survey infertile women. Structure Equation Modeling(SEM)and bootstrapping procedure were used to verify the mediating effect. Results The prevalence of psychological distress among infertile women was 79.6%. Spearman correlation analysis showed that there existed a moderate negative correlation between mindfulness level and perceived stress(r_s=-0.529, P<0.001), and psychological distress(r_s=-0.600, P<0.001); there was a moderate positive correlation between perceived stress and psychological distress(r_s=0.691, P<0.001). SEM indicated that mindfulness level had significant direct effects on perceived stress(β=-0.67, P<0.001)and psychological distress(β=-0.31, P=0.007); perceived stress had a significant direct effect on psychological distress (β=0.64, P<0.001). Furthermore, perceived stress mediated the relationship between mindfulness level and psychological distress. The 95% confidence interval(95%CI)from Bootstrap output was(-0.628, -0.299, P<0.001)and the mediating effect accounted for 58.1% of the total effect. Conclusion Psychological distress was common among infertile women. The mediating role of perceived stress may provide potential mechanism for exploring the relationship between mindfulness level and psychological distress.
