The notion that postnatal adjustment requires women’s selflessness is widely accepted but understudied. This study explored the utility of a combined (selflessness × differentiation of self) model in explaining postnatal adjustment. One hundred and seventy-eight women completed the following questionnaires: Differentiation of Self, The Selflessness Scale, The Selfishness Subscale of the Omnibus Self-Test, Maternal Attitudes Questionnaire, and Edinburgh Postnatal Depression Scale. The study findings partially support the suggested model. Both selflessness and differentiation were each found to have a significant direct effect on postnatal depression and mothers’ attitudes toward their baby. However, a quadratic effect of selflessness was found for maternal attitudes only, and interaction effect was not found. It is concluded that while these two variables may independently contribute to explaining postnatal adjustment, there is a need for an advanced multidimensional model to better understand their relationship in this context.

产后调整需要女性无私的观念被广泛接受，但并未得到充分研究。这项研究探索了组合（无私×自我分化）模型在解释产后调整中的效用。一百七十八名妇女完成了以下问卷调查：自我差异，无私量表，综合自测的自私子量表，产妇态度问卷和爱丁堡产后抑郁量表。研究结果部分支持建议的模型。无私和分化都被发现对产后抑郁和母亲对待婴儿的态度有直接的直接影响。但是，仅对母亲的态度发现了无私的二次效应，而没有发现相互作用效应。
