Daily experiences of sibling relational aggression: Links to Latino children's psychosocial and physical health

This study examined Latino children's daily experiences of sibling relational aggression as predictors of mood, physical health symptoms, and peer relations. Participants were 279 Latino older (Mage = 10.68; SD = 0.39; 47% female) and younger (Mage = 8.28; SD = 1.07; 48% female) siblings from predominantly immigrant families. Data were collected from siblings during seven daily calls and teachers rated peer relations. Daily average levels of and day-to-day variability in experiences of sibling relational aggression were associated with less positive and more negative mood and with more physical health symptoms for older and younger siblings. Sibling relational aggression also was associated with negative peer relations for siblings in mixed-sex dyads. Implications for prevention of sibling relational aggression are offered.
