Abstract

This study investigated sibling rivalry across South Asian and White College of Wooster students (N = 96, with n = 35 South Asian and n = 61 White participants) and explored its influence on psychological outcomes, namely resilience, motivation, self-esteem, and depression. Additionally, exploratory analyses aimed to uncover the moderating effect of sibling affection in the relationship between sibling rivalry and the above psychological outcomes. Participants completed surveys to assess sibling rivalry, affection, and the psychological outcomes. Interviews were conducted with participants who volunteered to expand on survey responses and explore whether competition remains within the sibling relationship or becomes a part of one’s personality. Results indicated that South Asian participants reported higher levels of sibling rivalry than White participants. Sibling rivalry was significantly associated with motivation, self-esteem, and depression but not significantly associated with resilience. Finally, the interaction between sibling rivalry and affection significantly predicted resilience but not motivation, self-esteem, or depression. Overall, these findings shed light on how cultural dynamics influence sibling rivalry. The interviews revealed that parental comparisons, perceived parental treatment, and cultural expectations were more commonly reported among South Asians, while strong sibling support was widely reported in both groups. Recognizing both the positive and negative psychological outcomes is crucial in developing effective interventions that minimize harmful sibling rivalry and enhance overall psychological well-being.
