Typically developing (TD) siblings play a crucial role in promoting the health and well-being of adults with intellectual disabilities. Their involvement in the sibling relationship during adulthood may predict their likelihood of providing care to the sibling with intellectual disabilities (ID). However, different types of motivations (discretionary and obligatory) related to the contact frequency of TD siblings have not been fully explored. Little is known about how their negative experiences, such as affiliated stigma, influences relational motivations, which consequently affect contact frequency. This study examined these links in a Chinese context. In total, 1,298 Chinese siblings were surveyed using questionnaires, and structural equation modelling was used to test the mediation effect. Contact frequencies of TD siblings were significantly affected by discretionary motivation, obligatory motivation, and stigma experiences. The findings supported the mediating effect of obligatory motivation in the relationship between affiliated stigma and contact frequency. This study is among the first to examine whether the relational motivation of TD siblings predicts their contact frequency within their relationships with adult siblings with ID. We found that both types of relational motivations of TD siblings positively predicted contact behavior.
发育正常（TD）的兄弟姐妹在促进成年智障人士的健康和幸福方面发挥着关键作用。他们在成年期参与兄弟姐妹关系可能预示着他们为智障（ID）兄弟姐妹提供照料的可能性。然而，与TD兄弟姐妹接触频率相关的不同类型动机（自主和义务）尚未得到充分探讨。对于他们的负面经历，如关联污名，如何影响关系动机进而影响接触频率，人们知之甚少。本研究在中国背景下考察了这些联系。总共对1298名中国兄弟姐妹进行了问卷调查，并使用结构方程模型来检验中介效应。TD兄弟姐妹的接触频率受到自主动机、义务动机和污名经历的显著影响。研究结果支持了义务动机在关联污名与接触频率关系中的中介作用。本研究是首批考察TD兄弟姐妹的关系动机是否能预测他们与成年ID兄弟姐妹关系中的接触频率的研究之一。我们发现，TD兄弟姐妹的两种关系动机都能正向预测接触行为。
