A latent class growth analysis approximated four discrete developmental trajectories of children’s externalizing (EXT) behavior from early to middle childhood. The chronic group (n = 9) had the highest EXT behavior among all groups over time. The rising group’s (n = 23) EXT behavior increased from a low to moderate level through childhood. The decreasing group’s (n = 38) EXT behavior decreased from a moderate to low level through childhood. The low group’s (n = 168) EXT behavior was lowest among all groups and decreased over time. Markers represent sample means. Solid lines connect estimated means.
