This study examined the predictive value of the triad (enuresis, firesetting, cruelty to animals) in a group of incarcerated sex offenders. The most salient positive finding in this investigation was the association between one or more components of the triad and a highly abusive home environment. There was no compelling evidence to support the prognostic value of the triad of behaviors for predicting adult criminal outcome. The triad appeared to be primarily a maladaptive response to the turmoil and abuse in the home prior to and during adolescence. Finally, it is noteworthy that this study revealed a much lower frequency of triad behaviors than has been reported in the literature.
