Given the longer lives of individuals with disabilities and the increasing likelihood of siblings fulfilling family caregiving roles, it is critical to identify correlates of sibling caregiving. Yet, little research has examined the relation between the severity of the disability and sibling caregiving. The purpose of this study was to understand the relation between the severity of the disability (defined as functional ability and maladaptive behaviors) and sibling caregiving, including advocacy and future planning. Adult siblings of older individuals with disabilities (N = 141) completed a national survey. Results indicated that individuals with less functional ability were significantly more likely to receive greater sibling caregiving, advocacy, and future planning. There was a nonlinear relation with respect to sibling caregiving and functional ability with individuals with severe disabilities requiring disproportionately greater sibling caregiving. Furthermore, there was a nonlinear relation between maladaptive behaviors and caregiving demands such that siblings of individuals with the greatest asocial behaviors reported significantly greater caregiving demands.

检查残疾老年人的残疾严重程度与兄弟姐妹照顾之间的关系

鉴于残疾人的寿命越来越长，兄弟姐妹履行家庭照料职责的可能性越来越大，因此确定兄弟姐妹照料的相关性至关重要。然而，很少有研究检查残疾的严重程度与兄弟姐妹照顾之间的关系。本研究的目的是了解残疾的严重程度（定义为功能能力和适应不良行为）与兄弟姐妹照料（包括倡导和未来规划）之间的关系。年长残障人士 (N = 141) 的成年兄弟姐妹完成了一项全国调查。结果表明，功能能力较差的人更有可能获得更多的兄弟姐妹照顾、倡导和未来规划。在兄弟姐妹照料和功能能力方面，与需要更多兄弟姐妹照料的重度残疾者之间存在非线性关系。此外，适应不良行为与照料需求之间存在非线性关系，因此具有最大反社会行为的个体的兄弟姐妹报告了显着更高的照料需求。
