Background: Typically developing (TD) siblings are an important part of the family system, but may show strained relationships in families of children with ASD.

Objective: We augmented a sibling support group with parent-sibling training in which parents learned (through instructions, modeling, rehearsal, and feedback) how to prompt and reinforce prosocial behaviors in their TD children.

Method: We examined the effects of parent-sibling training on parent and TD sibling behaviors in a multiple baseline across families design.

Results: Parent prompting and reinforcement of TD sibling prosocial behaviors increase. TD sibling prosocial behaviors such as sharing with and talking to their sibling with ASD also increased. Broader measures of the sibling relationship showed some improvements.

Conclusion: Findings suggest ways to support families of children with ASD with future investigations of parent-sibling training examining longer intervention, all family members’ adjustment and relationships, and sibling characteristics that influence response to parent-sibling training.

背景：通常发育中的（TD）兄弟姐妹是家庭系统的重要组成部分，但可能显示ASD儿童家庭关系紧张。

目标：我们通过兄弟姐妹培训扩大了兄弟姐妹支持小组，在该小组中，父母学习了（通过指示，建模，彩排和反馈）如何促进和加强其TD儿童的亲社会行为。

方法：我们在整个家庭设计的多个基准中，研究了父母兄弟姐妹培训对父母和TD兄弟姐妹行为的影响。

结果：父母对TD同胞亲社会行为的提示和强化增加。TD兄弟姐妹的亲社会行为，例如与ASD的兄弟姐妹共享或交谈。对同胞关系的更广泛的衡量显示出一些改善。

结论：研究结果提出了通过未来对父母兄弟姐妹培训的调查来支持ASD儿童家庭的方法，这些研究包括更长的干预，所有家庭成员的适应和关系以及影响对父母兄弟姐妹培训反应的兄弟姐妹特征。
