Abstract

Many cases of sibling fights, including crimes, are committed by young adults who are considered independent and responsible and have good psychological well-being. These cases are caused by parental injustice. Parenting patterns that create sibling rivalry. This study aims to determine whether there is a significant relationship between sibling rivalry and psychological well-being in early adults in Jakarta. The research method used is quantitative with the criteria for male or female respondents, aged 18-29 years, having at least one sibling and domiciled in Jakarta. The sibling rivalry variable uses the ASRQ Rivalry Subscale by Stocker 1997 and the psychological well-being variable uses the SPWB by Ryff & Keyes adapted by Fadhil 2021. The 114 respondent data were analyzed using SPSS and Spearman's rho correlation test. The results showed no significant relationship between sibling rivalry and psychological well-being in early adults in Jakarta (sig. 0.470 > 0.05). This means that higher levels of sibling rivalry do not necessarily increase or decrease psychological well-being, and vice versa. However, in the correlation matrix, sibling rivalry correlated positively with the Positive Relations with Others dimension (r = 0.214*, p = 0.022) and negatively with the Personal Growth dimension (r = -0.197*, p = 0.036)
