Sibling relationship is one of the longest-lasting social relationships鈥痠n a person鈥檚 life. However, studies鈥痳egarding鈥痵ibling relationships in adulthood are relatively limited. Using the Life Course Theory, a cross-sectional qualitative study was conducted to identify the development of sibling relationship quality (SRQ) across stages of adulthood (young, middle, and older adulthood)鈥痑nd different sibling gender pairings. The study also examined the associations between SRQ and subjective well-being,鈥痑nd the differences in subjective well-being among different sibling gender pairings. A total of 209 Malaysian adults were recruited through social media platforms and were asked to complete two questionnaires, the Lifespan Sibling Relationship Scale, and the Subjective Well-Being — Short Scale. Statistically significant differences were found, in which older adults reported the highest SRQ compared to younger and middle-aged adults.鈥� Additionally, a significant positive relationship was found between SRQ and subjective well-being.鈥疘n terms of sibling gender, same-sex sibling pairings have higher reports of鈥疭RQ,鈥痑nd subjective well-being compared to different-sex sibling pairings. These findings suggest that SRQ changes across different鈥痑dult鈥痩ife stages, and that siblings play an important role in one鈥檚 subjective well-being. The findings also underline the importance of sibling gender pairings in determining SRQ and subjective well-being.鈥�
