自我效能、妊娠压力对初产妇血清皮质醇水平的影响

Effect of self efficacy and pregnancy pressure on serum cortisol levels in primiparas

目的了解初产妇孕晚期自我效能、妊娠压力、血清皮质醇关系，探讨自我效能在妊娠压力与皮质醇水平之间的中介效应和调节效应。方法采用便利抽样，用自我效能量表（CSES）、妊娠压力量表（PPS）测量被试者自我效能和妊娠压力，采集279例初产妇静脉血测量血清皮质醇水平。结果被试者自我效能、妊娠压力、血清皮质醇之间均显著相关，自我效能起到部分中介效应和调节效应，中介效应占总效应的比例为32．6％。结论自我效能在妊娠压力和血清皮质醇水平的关系中起到部分中介和调节效应。

Objective To describe self efficacy, pregnancy pressure and serum cortisol levels during late pregnancy period in primiparas and explore the mediating effects and regulating effects of self efficacy between pregnancy pressure and serum cortisol levels. Methods By convenient sampling, General Self- efficacy Scale and Pregnancy Pressure Scale were conducted to estimate the self-efficacy and pregnancy pressure in primiparas. Maternal venous blood was collected to measure cortisol levels. Results The self- efficacy was positively related to pregnancy pressure and cortisol levels. Self-efficacy has acted partial me- diating effects and regulating effects between pregnancy pressure and cortisol levels in primiparas, the me- diating effect to the total effect was about 32.6%. Conclusions Self-efficacy has acted partial mediating effects and regulating effects between pregnancy pressure and cortisol levels in primiparas.
