Validation study reveals a four-factor structure for the Sibling Relationship Scale in emerging adults, highlighting cultural and developmental influences on sibling bonds.
The development of sibling relationships across the life course can be context and culture specific. The current study aimed to adapt and validate a new measure of sibling relationship quality the Emerging Adults’ Relationship with Sibling Scale (EARSS) to assess Turkish emerging adults’ sibling relationships. In Sample 1 ( n = 407), factor structure with exploratory factor analysis (EFA) was investigated. In Sample 2 ( n = 283), the factor structure of EARSS was determined by confirmatory factor analysis (CFA). EFA results showed that EARSS had four-factor structure: closeness, parent-mediated relationship, ill-wishes, and conflict. CFA results indicated that four-factor structure model showed acceptable fit. Convergent validity analysis demonstrated strong correlations between depression, life satisfaction, and the sub-scales of EARSS. Findings show that sibling relationships are influenced by developmental stage and cultural context, impacting dimensions such as closeness and parent-mediated interactions.
