Aggression between siblings can possibly be explained by the quality of the sibling relationship and gender. The aim of the current study is to investigate whether anger in response to a sibling, as an indicator of the quality of the sibling relationship, is related to sibling aggression and whether gender plays a moderating role. A sample of 18 sibling pairs (oldest sibling: aged 10 to 18 years, M = 14, SD = 1.9) participated. The aggression between siblings was measured with the sibling version of the Conflict Tactics Scale, CTS2-SP. To measure anger in response to provocative behavior of the sibling a Virtual Reality (VR) task was used. The provocative behavior was believed to be controlled by their sibling but was actually an avatar. The participants were also asked if they believed if their sibling controlled the avatar during the VR task. The scores of the oldest sibling of the pairs were included. The results showed that anger in response to the sibling was not related to sibling aggression and that participants showed equal aggression towards their sibling. Also, no gender differences were found between participants in the link between anger and aggression, so gender did not play a moderating role. It seems that gender differences in siblings play a smaller role than in boys and girls for showing aggression. The results suggest that aggression between siblings might be more normal and accepted than aggression between boys and girls and that siblings may be more used to each other compared to non-family related children. However, further research is needed, to understand the phenomenon of sibling aggression even better in order to prevent it, since the consequences of sibling aggression can be profoundly serious.Show less

During childhood and adolescence, the relationship between siblings changes especially in the amount of warmth and conflict between them. Previous research shows that the experience of differential parenting can cause feelings of jealousy, which in turn affects the quality of the sibling relationship in forms of less warmth and more physical or psychological aggression. The current cross-sectional study examined the relation between differential parenting and physical or psychological aggression between siblings and the potential moderating role of the warmth within the sibling relationship. The sample consisted of 22 children between 9 and 18 years old and their 19 younger siblings also between 9 and 18 years old. The study used online self-report questionnaires to measure the experienced differential parenting (SIDE), sibling physical and/or psychological aggression (CTS2-SP) and the perceived warmth within the sibling relationship (SRQ-S). The results showed a significant relation between differential parenting and psychical or psychological aggression within the sibling relationship for the youngest siblings. This means that when the youngest sibling is experiencing differential parenting, there also will occur more physical or psychological aggression. This relation remained significant when controlling for warmth between the sibling relationship. This relation was not found for the older siblings, which means that when the older siblings experience differential parenting this will not lead to physical or psychological aggression. No significant moderation effect was found for warmth within the sibling relationship on the relation between differential parenting and physical and/or psychological aggression for both the oldest and youngest siblings. Future research should focus more on the possibilities that sibling relationships can offer, especially which protective role a sibling relationship might have. It is also important that parents become more aware of how their children might experience certain parental behavior and what consequences this might have.Show less
