RESUMO
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.
