摘　　要：目的了解自我和谐在医学研究生应激与抑郁间的作用机制。方法于2015年3月采用整群随机抽样方法抽取哈尔滨医科大学550名医学研究生进行问卷调查,使用SPSS 17.0进行统计分析,包括描述性分析、相关分析和分层回归分析。结果医学研究生中无健康危险性压力者282人(57.67%),有健康危险性压力者207人(42.33%);自我和谐低分组62人(12.68%),中间组364人(74.44%),高分组63人(12.88%);无抑郁症状者483人(98.77%),有抑郁症状者6人(1.23%);医学研究生应激总分与抑郁总分呈正相关(r=0.510,P=0.000),与自我和谐总分呈正相关(r=0.494,P=0.000);医学研究生抑郁总分与自我和谐总分呈正相关(r=0.648,P=0.000);分层回归分析结果显示,当自我和谐进入回归方程后,应激对抑郁的回归系数变小,且达到显著水平(P<0.01)。结论医学研究生自我和谐在应激与抑郁间起到部分中介作用。Objective To explore the role of self-consistency and congruence on the relationship between stress anddepression among medical postgraduates. Methods Totally 550 medical postgraduates were selected with cluster random sampling and surveyed with Perceived Stress Scale （ PPS）, Self-Rating Depression Scale （ SDS）, and Self Consistency and Congruence Scale （SCCS）. Descriptive analysis, correlation analysis, and hierarchical regression analysis were per- formed with SPSS 17.0. Results Of the postgraduates,282 （57.67%）reported perceived stress for health risk and 207 （42. 33% ）did not reported the stress. The number of the postgraduates had low,intermediate, and high score of self-con- sistency and congruence were 62（ 12. 68% ） ,364 （74. 44% ）, and 63 （ 12. 88% ）, respectively. Only 6 （ 1.23% ） were de- tected with depression symptoms and 483 （98. 77% ）showed no depression symptoms. The overall stress score was posi- tively correlated with total depression score （ r = 0. 510, P = 0. 000 ） and total score of self-consistency and congruence （ r = 0. 494, P = 0. 000） ; the total depression score was positively associated with the total score of self-consistency and congruence （ r = 0. 648, P = 0. 000）. The results of hierarchical regression analysis showed that the regression coefficient between stress score and depression score diminished significantly when the score of self-consistency and congruence was introduced into the regression equation（ P 〈0. 01 ）. Conclusion Self-consistency and congruence plays a partial interme- diary role on the relationship between stress and depression among medical postgraduates.
