“…These results suggest that, indeed, there is a different criminal trajectory in each group: the generalist batterer is younger and with an earlier onset in his criminal activities, which by definition is more varied. This finding would be consistent with research showing that the age of delinquency onset is inversely related to the number of offenses (Mazerolle, Burton, Cullen, Evans, & Payne, 2000;McGloin, Sullivan, Piquero, & Pratt, 2007;Piquero, Paternoster, Mazerolle, Brame, & Dean, 1999) and that younger and persistent offenders tend to have a more varied criminal history (Arce, Fariña, & Vázquez, 2011), including partner violence (Mazerolle & Maahs, 2000).…”
