Conduct problems (CP) and callous-unemotional (CU) traits can have a long-lasting negative impact into adulthood. Importantly, among youth with CP, those high on CU traits engage in a more severe, aggressive, and persistent pattern of antisocial behavior. The current study investigates the co-occurrence between CP and CU traits among a large sample of Greek-Cypriot adolescents (N = 1,674; 50.1 % girls). Five distinct groups were identified with Latent Profile Analysis: low risk (48.7 %), average risk (33.8 %), co-occurring high CP-high CU (5.4 %), high CP-low CU (5.2 %), and low CP-high CU (6.9 %). Although more boys were identified in the higher risk groups, boys and girls within each group were not differentiated on levels of CP or CU traits during early adolescence. Youth in the identified groups were compared on early (Mean age = 12.12) and middle (Mean age = 14.02) adolescence …
