Although sibling ties are typically among the longest lasting family relationships, relatively little is known about how adult siblings navigate family caregiving when a brother or sister has a serious mental illness. The present study examined the role of primary caregiver status, perceived sibling illness severity, sibling relationship quality, and self and sibling caregiving attitudes in understanding reports of personal loss and stress-related personal growth among siblings of adults with serious mental illness. Online surveys were completed by 226 adult siblings (141 women; 85 men; mean age = 34 years; SD = 9.05). Results suggest that well siblings' reports of self and sibling caregiving attitudes significantly differed as a function of primary caregiver status (i.e., sibling, parents, or others as primary caregiver or no caregiver). Sibling caregiving attitudes differentially predicted well siblings' experience of personal loss and stress-related growth, regardless of demographics and primary caregiver status, perceived sibling illness severity, and sibling relationship quality. Greater ambivalence about providing care to their sibling with mental illness was associated with adults' reports of greater personal loss while higher levels of sibling balanced care priorities were significantly related to higher levels of personal growth. Greater self-care attitudes were significantly related to lower levels of both personal loss and personal growth for well siblings. Understanding sibling caregiving attitudes has important implications for research and interventions with families coping with mental illness.

患有精神疾病的成年人的兄弟姐妹中的自我和兄弟姐妹照顾态度、个人损失和压力相关的成长。

尽管兄弟姐妹关系通常是最持久的家庭关系之一，但当兄弟姐妹患有严重的精神疾病时，成年兄弟姐妹如何处理家庭照料却知之甚少。本研究调查了主要照顾者的地位、感知的兄弟姐妹疾病严重程度、兄弟姐妹关系质量以及自我和兄弟姐妹的照顾态度在理解患有严重精神疾病的成年人的兄弟姐妹的个人损失和压力相关的个人成长报告中的作用。在线调查由 226 名成年兄弟姐妹完成（141 名女性；85 名男性；平均年龄 = 34 岁；SD = 9.05）。结果表明，作为主要照顾者身份的函数（即兄弟姐妹、父母或其他人作为主要照顾者或无照顾者），健康兄弟姐妹对自我和兄弟姐妹照顾态度的报告存在显着差异。无论人口统计学和主要照顾者的身份、感知的兄弟姐妹疾病严重程度和兄弟姐妹关系质量如何，兄弟姐妹的照顾态度都不同地预测了兄弟姐妹的个人损失和与压力相关的成长经历。对于为患有精神疾病的兄弟姐妹提供护理的更大矛盾与成年人报告更多的个人损失有关，而更高水平的兄弟姐妹平衡护理优先级与更高水平的个人成长显着相关。更好的自我照顾态度与健康兄弟姐妹的较低水平的个人损失和个人成长显着相关。了解兄弟姐妹的照顾态度对研究和干预患有精神疾病的家庭具有重要意义。（PsycInfo 数据库记录 (c) 2020 APA，保留所有权利）。
