Parentification, distress, and relationship with parents as factors shaping the relationship between adult siblings and their brother/sister with disabilities.

According to parentification theory, when the siblings of a brother/sister with disabilities assume parent-like duties, this role reversal is known as sibling-focused parentification. It has a significant impact on these siblings' distress and the quality of their family relationships; 605 Italian adult siblings (19-26 years) of people with disabilities completed the online survey. Measures of siblings' parentification, distress, quality of family relationships, social support, and perceived benefits of parentification were used.
