Objective:To examine the potential mediating effect of mindfulness on personality traits and psychological distress.Methods:A total of 172 oncology nurses [mean age(32 ±7) years] in Shandong Province were selected.They were assessed with Big Five Inventory (BFI),Mindful Attention Awareness Scale (MAAS) and 10-item Kessler Psychological Distress Scale (K10) for the evaluation of personality traits,mindfulness and psychological distress.Bootstrap was used to test the mediating effect.Results:The mean score of K10 was (22.3 ±6.5) among oncology nurses,and 50.6％ of them had psychological distress problems.The K10 scores were negatively correlated with the scores of extroversion,agreeableness,conscientiousness and MAAS scores (r =-0.29,-0.31,-0.31,-0.48,Ps ＜ 0.01),and the K10 scores were positively correlated with neuroticism scores (r =0.40,P ＜0.01).The confidence interval from Bootstrap output indicated mindfulness played a partial mediating role between neuroticism and psychological distress (95％ CI:0.05-0.28),the value of mediating effect was 27.1％.Conclusion:The relation of mindfulness to personality traits and psychological distress among oncology nurses are intimate.Mindfulness could mediate the relationship between neuroticism and psychological distress.%目的:探讨正念在肿瘤科护士人格特征和心理困扰之间的中介作用.方法:选取山东省肿瘤科护士172名[平均(32±7)岁],采用大五人格问卷(BFI)、正念注意觉知量表(MAAS)、Kessler10量表(K10)调查其人格特征、正念水平及心理困扰情况.采用Bootstrap检验进行中介作用分析.结果:肿瘤科护士的K10平均得分为(22.3±6.5),50.6％的肿瘤科护士存在心理困扰问题.K10得分与BH的外倾性、宜人性、尽责性得分及MAAS总分均呈负相关(r=-0.29、-0.31、-0.31、-0.48,均P＜0.01),而与神经质得分呈正相关(r=0.40,P＜0.01).Bootstrap检验结果显示正念在神经质人格和心理困扰间的95％CI为0.05～0.28,中介效应占总效应的27.1％.结论:肿瘤科护士的人格特征和正念与心理困扰关系密切,正念可以中介神经质人格与心理困扰之间的关系.
