The Open Psychology Journal 11 June 2020 RESEARCH ARTICLE DOI: 10.2174/1874350102013010101

Abstract

Background:

The quality of sibling relationships is an important factor in the development of individuals, particularly in the context of a relationship with a brother or sister with disabilities.

Aims:

This research aims to assess the moderating role of the quality of the relationship with siblings between personality traits and coping strategies.

Methods:

The participants were 187 adults, of whom 97(51.9%) were Individuals with brothers or sisters with intellectual disabilities (S-IDs), aged 18 to 60 years (M=30.22; SD=12.17). The second group was 90 (48.1%) Individuals with typical developmental siblings (S-TDs) aged 18 to 76 years (M=28.56; SD=11.66). Respondents completed the Big Five Questionnaire (BFQ), the Coping Orientation to Problem Experiences (COPE), and the Adult Sibling Relationships Questionnaire (ASRQ).

Results:

The data show a correlation between personality traits and coping strategies. In addition, the size of the ASRQ was found to moderate the relationship between personality traits and coping strategies, albeit in a different way between the two groups.

Conclusion:

The quality of the reality with brothers or sisters turns out to be an important factor in the development, and it is found to mediate the relationship between personality traits and the development of coping strategies, both in S-TDs and S-IDs, presenting similarities and differences. Future research guidelines have been discussed.
