Issues of equality and fairness and invasion of the personal domain, 2 previously identified topic areas of adolescent sibling conflict (N. Campione-Barr & J. G. Smetana, 2010), were examined in 145 dyads (Mfirst-born = 14.97, SD = 1.69 years; Msecond-born = 12.20, SD = 1.90 years) for their differential effects on youths' emotional adjustment over 1 year. The impact of internalizing symptoms on later sibling conflicts also was tested. Invasion of the personal domain conflicts were associated with higher levels of anxiety and lower self-esteem 1 year later, whereas Equality and Fairness issues were associated with greater depressed mood. Conversely, greater internalizing symptomatology and lower self-esteem predicted more of both types of conflict. Moderating influences of gender and ordinal position were also examined.
