A model of stress process among mothers of infants was retested. In that model, stressors (work status or infant difficultness) influence maternal identity through perception of stress. Also, maternal identity may be buffered from stressor effects by health-promotive lifestyle. This model previously received partial support in a one-panel mail survey. The present study reports maternal outcomes from a 6-month follow-up of the original sample. One hundred nineteen (69%) mothers of infants aged 8-20 months participated in the follow-up study. Despite subject attrition, most findings from the original study were replicated in this study. As before, work status and perceived stress each contributed to predicting identity. Health-promotive lifestyle acted directly, not as a buffer, on maternal identity. When extraneous influences were controlled, neither perceived stress nor health-promotive lifestyle was significantly correlated across a 6-month period.
对一个关于婴儿母亲压力过程的模型进行了重新测试。在该模型中，压力源（工作状态或婴儿难养程度）通过压力感知影响母亲身份认同。此外，促进健康的生活方式可能会缓冲压力源对母亲身份认同的影响。该模型此前在一项单组邮件调查中得到了部分支持。本研究报告了对原始样本进行6个月随访后的母亲相关结果。119名（69%）8至20个月大婴儿的母亲参与了随访研究。尽管有样本流失，但本研究重复了原始研究的大部分结果。和之前一样，工作状态和感知到的压力都有助于预测身份认同。促进健康的生活方式对母亲身份认同有直接作用，而非起到缓冲作用。当控制了外部影响因素后，在6个月的时间里，感知到的压力和促进健康的生活方式之间均无显著相关性。
