Previous research indicates the importance of having high levels of attachment with parents in order to realise positive outcomes of psychological and subjective well-being in later-life. Additionally, sibling attachment in childhood may impact future psychological and subjective well-being directly and independently from parental influences. To our knowledge, there is no existing study that examines the moderating role of sibling attachment on the association between parental attachment and later-life well-being. Participants (n = 254) were asked to retrospectively rate their attachments to their parents and the sibling closest in age to them. Additionally, they completed self-report questionnaires probing current levels of depression, anxiety, stress, self-esteem, and satisfaction with life. The expected significant relationships between childhood attachments and later-life well-being were found for maternal and sibling attachments, but not paternal attachment. Furthermore, retrospectively-rated sibling attachment seemed to be a stronger predictor of later-life well-being than paternal attachment. Taken together, these findings indicate the importance of early-life attachment figures on future well-being. Furthermore, these findings concur with the general propositions of attachment theory, arguing that experiences with attachment figures during childhood heavily shape an individual’s developmental trajectory and their internal working models about the self, others, and the world. However, sibling attachment was not found to moderate the relationship between parental attachment and later-life psychological and subjective well-being. Speculative explanations as to why a moderating effect was not found include limited sibling resources, innate attachment effects, and contrast effects.

先前的研究表明，与父母保持高度的依恋关系对于在以后的生活中实现心理和主观幸福感的积极结果至关重要。此外，儿童时期的兄弟姐妹依恋可能会直接且独立于父母的影响而影响未来的心理和主观幸福感。据我们所知，目前尚无研究研究兄弟姐妹依恋对父母依恋与晚年幸福感之间关系的调节作用。参加人数 = 254）被要求回顾性评估他们对父母的依恋以及与他们年龄最接近的兄弟姐妹的依恋。此外，他们完成了自我报告调查表，以调查当前的抑郁，焦虑，压力，自尊和生活满意度。在母亲和兄弟姐妹的依恋中发现了儿童依恋与晚年幸福感之间的预期显着关系，而父亲的依恋则没有。此外，回顾性评估的兄弟姐妹依恋似乎比父亲的依恋更能预测晚年的幸福感。综上所述，这些发现表明了早期依恋数字对未来幸福感的重要性。此外，这些发现与依恋理论的一般命题一致，争论说，儿童时期对依恋者的经历会严重影响一个人的发展轨迹以及他们关于自我，他人和世界的内部工作模式。但是，没有发现同胞依恋能够缓和父母依恋与以后的心理和主观幸福感之间的关系。关于为什么未发现调节效果的推测性解释包括有限的同级资源，先天依恋效果和对比效果。
