= 9,476) supported a mediation model where higher IPC at age 4-5 years was associated with higher indications of self-regulation difficulties at age 10-11 years, which in turn predicted higher depressive symptoms, anxious symptoms, and antisocial behavior at age 14-15 years. Evidence of moderation by child sex was found. The relationship between IPC, indicators of self-regulation difficulties, and antisocial behavior was stronger for males than females, while the relationship between indicators of self-regulation difficulties and internalizing outcomes was stronger for females compared to males. These results are interpreted using perspectives on biopsychosocial development, and implications for intervention at multiple time points are discussed.
