D型人格对大学新生心理健康的影响:基于三个时间点调查数据的有调节的中介模型

为考察感知到的压力在D型人格与大学新生心理健康关系中的中介作用及心理韧性的调节作用。在新生入学3个月内的不同时间点，利用D型人格量表（T1）、心理韧性量表（T2）、感知到的压力量表（T2）和心理健康量表（T3）对某大学1428名大学新生进行调查。结果显示：（1）在控制性别、年龄、是否恋爱和心理健康（T1）后，社交抑制对感知到的压力具有显著预测作用，感知到的压力对心理健康具有显著预测作用，即社交抑制通过感知到的压力的中介作用间接影响心理健康；在负性情感与心理健康的关系中，感知到的压力中介作用不成立；（2）心理韧性在社交抑制与心理健康的关系中调节效应显著；心理韧性在感知到的压力与心理健康的关系中调节效应显著；（3）一个有调节的中介模型成立。研究结果不仅有助于理解大学新生适应大学生活过程中的心理状况，而且为提高大学新生心理健康水平提供参考依据。

The Effect of Type D Personality on College Freshmen's Mental Health: A Three-wave Moderated Mediation Analysis

The present study is aimed to explore the mediating effect of perceived stress on the relationship between type D personality and freshmen's mental health and whether it is moderated by resilience. 1428 freshmen in a university was investigated at different points during the first three months using the type D personality scale(T1), the resilience scale(T2), the perceived stress scale(T2), and the mental health scale(T3). Results showed that:(1)After controlling for gender, age, dating and mental health (T1), social inhibition significantly predicted perceived stress, and perceived stress significantly predicted mental health. Social inhibition indirectly affects mental health through the mediating effect of perceived stress. However, perceived stress did not mediate the relationship between negative affection and mental health; (2)Resilience moderated the relationship between social inhibition and mental health and the relationship between perceived stress and mental health; (3)A moderated mediation model was confirmed.
