Objective: Sibling relationships are important for the individual development of a child. The aim of this study is to investigate whether warmth and conflict in sibling relationships influence the global self-worth of adolescents and the role that sex and birth-order plays in this influence. Method: Participants were 579 Dutch adolescents, in the first grade of high school (M = 12.48 years old). The quality of their sibling relationship (warmth and conflict), was measured with the Sibling Relationship Questionnaire (Furman & Burhmester, 1990). The CBSK-A (based on the CBSK, Kievit, Tak, & Bosch, 2009) has been used to measure the global self-worth. Results: Results provide evidence regarding the positive effect of warmth in the sibling relationship and the global self-worth of adolescents. Testing for sex and birth-order shows significant results for girls only. Conflict appears to have no significant effect for all concepts. Conclusion: A higher level of warmth in the sibling relationship increases the global self-worth.
