Jenna C. Dayley , Utah State University Follow. As the longest lasting close relationship, often extending from birth until death, sibling relationships play an important role throughout the life course. To date, however, only limited work has examined the process by which siblings influence each other during young adulthood. Given that developmental differences between older and younger siblings diminish in young adulthood, it is possible that bidirectional older-to-younger as well as younger-to-older are more likely as compared to adolescence in which top-down or older-to-younger influence has primarily been explored.
This three-study dissertation addressed these possibilities using extant data from three different studies. Further, this study examined the degree to which sibling closeness exacerbated sibling similarities across these various domains. Next, Study 2 examined whether sibling relationship qualities i. Across the three studies, findings suggested that through different processes, siblings continue to influence each other during young adulthood. Overall, evidence for bidirectional sibling influence emerged in domains in which development was ongoing for both older and younger siblings during young adulthood e.
Across Studies 1 and 3, results did not support hypotheses that sibling modeling would promote greater similarities between young adult siblings. Discussion focuses on the themes found across the studies and outlines future directions for research with siblings during young adulthood.
