Children with aggressive behavior problems may aggress for different reasons, requiring tailored assessment and treatment. The aim of this study was to test whether it is possible to detect distinct social information processing (SIP) profiles among boys with aggressive behavior problems. We therefore conducted Latent Profile Analyses on boys' SIP patterns assessed in interactive virtual reality. Additionally, we examined the discriminant validity of these SIP profiles by comparing them on theoretically relevant child characteristics (i.e., temperament, executive functioning, aggressive belief systems, punishment insensitivity, sensation seeking). We presented boys (N = 181; ages 7-13) with a virtual classroom where they could play games with virtual peers. They reported on their SIP in four virtual reality scenarios, designed to assess reactive and proactive aggressive SIP. Results revealed four distinct SIP profiles: a general reactive SIP profile, a situation-specific reactive SIP profile, a mixed reactive-proactive SIP profile, and a nonaggressive SIP profile. Planned contrasts revealed that boys with these SIP profiles differed in temperament, aggressive belief systems, and punishment insensitivity, but not in executive functioning and sensation seeking. Overall, findings suggest that boys differ in the exact SIP patterns underlying their aggressive behavior, providing inroads to tailor interventions to children's individual needs.
