Psychological well-being in adolescents: examining the role of sibling rivalry

During adolescent development, it is not uncommon to encounter problems such as juvenile delinquency. Juvenile delinquency is a result of low levels of psychological well-being. One of the things that is a factor forming good psychological well-being in adolescents is the family environment. Problems that are often found in the family sphere are forms of parental support and adolescent egocentricity that tends to be high. If parents show rivalry and hostility in sibling relationships, it will have an impact on the emergence of negative experiences, in the form of sibling rivalry reactions. The purpose of this study was to examine whether sibling competition has a role in the psychological well-being of adolescents. Participants consisted of 147 grade 10 students of SMAN X Bondowoso using purposive sampling. The scale of sibling competition and the scale of psychological well- being were constructed and through factor analysis tests to obtain a fit model as an instrument of this study. Regression analysis showed sibling competition played a significant role in psychological well-being with a contribution of 13.7%. The impact of sibling competition, both in positive and negative terms, has a link to psychological well-being. Thus, the hypothesis of this study can be proven and accepted.
