Hey, that’s my shirt

Whether it is about who gets to ride shotgun or who wore a shirt without asking, siblings fight. While seemingly innocent, a recent MU study reveals that certain types of fights can affect the quality of sibling relationships. MU researchers identified two major types of conflict among adolescent siblings and found that conflicts about personal space have a negative impact on trust and communication between siblings.

“The first conflict area we found includes issues about physical and emotional personal space, such as borrowing items without asking and hanging around when older siblings have friends over,” says Nicole Campione-Barr, assistant professor of psychological sciences. “When these issues were present, both younger and older siblings reported less trust and communication. The second conflict area includes equality and fairness issues, such as taking turns and sharing responsibilities. These conflicts had no impact on relationship quality.”

Research findings suggest that older siblings are more sensitive to personal space issues and may indicate the beginning of their separation from the family. The study findings can help parents, psychologists and other individuals who work with teens understand the impact that conflicts can have on sibling relationships.

For parents, Campione-Barr suggests setting up family boundaries to reduce sibling conflicts about personal space. “Parents need to establish and enforce family rules about respecting privacy, personal space and property,” Campione-Barr said. “However, when sibling conflicts occur, there needs to be negotiations between siblings. Previous research tells us that parents should step aside because they have a tendency to make matters worse.”
