The MacDonald triad is composed of three developmental markers, including cruelty to animals, firesetting, and enuresis after the age of 5. Although there has been considerable interest in this construct initially, research has produced inconsistent results regarding its validity in terms of distinguishing between offender and non‐offender populations, or predicting future offences. The current study investigated the links between the triad, dimensions of psychopathology, and trajectories of aggression in a sample of 254 rapists previously collected from a single forensic mental health institution in the United States.
