The systematic review aimed to systematize the empirical literature on the psychological impact of disability on the siblings of persons with disabilities, to inform research and provide clinical recommendations. Two research questions addressed the review: (1) What are the main psychological constructs investigated in siblings of persons with disability? (2) What is the main role of each psychological construct in siblings of persons with disability experience? The electronic search was conducted in 7 databases and the PRISMA diagram was used. The inclusion criteria were: Papers published in English and in peer-reviewed journals; papers published between January 2014 and June 2024; qualitative, quantitative, and mixed studies; and papers on the psychological impact of disabilities and/or chronic illnesses on the experience of siblings of persons with disabilities. The standardized Mixed Method Appraisal Tool protocol was used to appraise the methodological quality of the studies. To summarize the findings, a narrative approach was adopted. A total of 60 studies have been reviewed. According to the methodological quality appraisal of studies, most of them reported a high (n = 45) and medium (n = 15) quality. They involved 10,146 participants. Findings revealed that sibling relationships, sibling-focused parentification, and emotional/behavioral adjustment are the main psychological constructs investigated by existing literature. Few studies focused on siblings’ well-being. Studies exploring more than a psychological construct were included as a hybrid. Only one study examined the siblings’ psychological experience during the COVID-19 pandemic. The quality of the sibling relationship ranged from good to poor; the caregiver is the main role played by siblings of persons with disabilities; anxiety, depression, and aggressive behaviors are the main emotional/behavioral symptoms revealed. Most studies (n = 39) recruited participants with brothers or sisters with mental disorders. The findings of this systematic review may play a role in the clinical field, as they might help to design gender- and age-specific intervention programs.

系统评价旨在将有关残疾对残疾人兄弟姐妹的心理影响的实证文献系统化，为研究提供信息并提供临床建议。本综述涉及两个研究问题：（1） 在残疾人的兄弟姐妹中调查的主要心理结构是什么？（2） 每个心理结构在残疾人经历的兄弟姐妹中的主要作用是什么？在 7 个数据库中进行电子检索，并使用 PRISMA 图。纳入标准是：以英文和同行评审期刊发表的论文;2014 年 1 月至 2024 年 6 月期间发表的论文;定性、定量和混合研究;以及关于残疾和/或慢性疾病对残疾人兄弟姐妹经历的心理影响的论文。使用标准化的混合方法评价工具方案来评价研究的方法学质量。为了总结研究结果，采用了叙述方法。共审查了 60 项研究。根据研究的方法学质量评价，大多数研究报告了高 （n = 45） 和中等 （n = 15） 质量。它们涉及 10,146 名参与者。研究结果表明，兄弟姐妹关系、以兄弟姐妹为中心的育儿和情绪/行为调整是现有文献研究的主要心理结构。很少有研究关注兄弟姐妹的幸福感。探索的不仅仅是一种心理结构的研究被纳入为混合体。只有一项研究调查了兄弟姐妹在 COVID-19 大流行期间的心理经历。 兄弟姐妹关系的质量从好到差不等;照顾者是残疾人士的兄弟姐妹所扮演的主要角色;焦虑、抑郁和攻击性行为是揭示的主要情绪/行为症状。大多数研究 （n = 39） 招募了有精神障碍兄弟姐妹的受试者。本系统综述的结果可能在临床领域发挥作用，因为它们可能有助于设计针对特定性别和年龄的干预计划。
