Perceived stress has been associated with fewer health-promoting behaviors in new primiparous mothers, but less is known about the mechanisms responsible for such effects.
The objective of this study was to examine the hypothesis that the relationship between perceived stress and health-promoting behaviors is mediated partially by a primiparous mother's sense of optimism. The transactional model of stress and coping and the model of behavioral self-regulation were used as the theoretical framework for the study.
An ex post facto cross-sectional design was used for this study. Participants consisted of 174 primiparous mothers who had given birth within the previous 12 months. Participants completed a self-reported online questionnaire consisting of the Perceived Stress Scale, the Health-Promoting Lifestyle Profile II, and the revised Life Orientation Test.
Results indicated that perceived stress predicted less health-promoting behaviors in new primiparous mothers (p < .001). Importantly, this relationship was mediated partially by the optimism displayed by the mother (p < .001).
The findings indicated that optimism partially mediated the relationship between perceived stress and health-promoting behaviors in new primiparous mothers. The implications for psychological practice are discussed.
感知压力与新初产妇较少采取促进健康的行为有关，但对于导致这种影响的机制知之甚少。
本研究旨在检验以下假设，即感知压力与促进健康行为之间的关系部分受初产妇乐观感的中介。应激与应对的交互作用模型和行为自我调节模型被用作本研究的理论框架。
本研究采用回顾性横断面设计。参与者由 174 名在过去 12 个月内分娩的初产妇组成。参与者完成了一份自我报告的在线问卷，其中包括感知压力量表、健康促进生活方式量表 II 和修订后的生活取向测验。
结果表明，感知压力预示着新初产妇较少采取促进健康的行为（p<0.001）。重要的是，这种关系部分由母亲表现出的乐观所中介（p<0.001）。
研究结果表明，乐观部分中介了新初产妇感知压力与促进健康行为之间的关系。讨论了心理实践的意义。
