目的 探究医学院校研究生的知觉心理压力在其导师指导风格倾向与研究生幸福感之间的中介作用。方法 2021年2月,采用导师指导风格量表、知觉心理压力量表和总体幸福感量表对某医学院校208名研究生进行问卷调查,采用Spearman相关分析和中介检验等方法分析相关数据。结果 研究生的知觉心理压力评分为(25.69±5.92)分,幸福感评分为(77.30±13.64)分,其导师指导风格倾向的评分为(0.78±0.22)分。研究生的导师控制型指导风格倾向与知觉心理压力呈显著正相关(r_s=0.16,P=0.026),与幸福感呈显著负相关(r_s=-0.27,P<0.001),幸福感与知觉心理压力呈显著负相关(r_s=-0.72,P<0.001);知觉心理压力在导师指导风格倾向和研究生幸福感之间的中介作用显著(95%CI=-13.40~-0.67),且中介效应值(-6.64)占总效应值(-17.06)的38.9%。结论 倾向于控制型指导风格的导师,其研究生幸福感水平较低。研究生的知觉心理压力在其导师指导风格倾向与研究生幸福感之间具有中介作用。

Objective To explore the mediating role of perceived stress among medical school graduate students in the relationship between the supervisor's guidance style and graduate students' general well-being. Methods In February 2021, a survey covering 208 graduates in a medical school was conducted using the supervisor's guidance style schedule, Perceived Stress schedule and General Well-Being schedule. The survey data were analyzed by spearman correlation analysis and mediation test. Results Graduate students scored (25.69 ± 5.92) for perceived stress, (77.30±13.64) for well-being, and (0.78±0.22) for their supervisor's guiding style. There was a significant positive correlation between perceived stress and supervisor's tendency to have a controlling mentoring style (r_s=0.16, P=0.026). A significant negative correlation between supervisor's guiding style and general well-being (r_s=-0.27,P<0.001) and between perceived stress and general well-being (r_s=-0.72,P<0.001) was found. The mediating effect of perceived psychological stress between supervisor's guiding style and graduate's general well-being was significant (95%CI=-13.40~-0.67), and the effect value (-6.64) accounted for 38.9% of the total effect value (-17.06). Conclusions Graduate students mentored by the supervisors who have a controlling mentoring style manifest a lower level of well-being. Graduate students' perceived stress mediates the relationship between their supervisor's guiding style and general well-being.
