exacerbated by the formation <strong>of</strong> affiliations with delinquent peers who may act toencourage, reward, and sustain tendencies to antisocial behaviours’.Fergusson and Horwood (2002) identified five distinct groups <strong>of</strong> <strong>of</strong>fenders in their NewZealand study. The low-risk trajectory group had very low levels <strong>of</strong> conduct problems (less than 2%)during mid-childhood (8-10 years). Offending was scarce during adolescence butincreased slightly at 17 years, declining thereafter. This group had a low rate <strong>of</strong><strong>of</strong>fending with a reported 1.6 <strong>of</strong>fences over the period from 14 to 20 years.The early onset trajectory group had relatively low rates <strong>of</strong> conduct problems duringmid-childhood (approximately 8%). The group displayed a moderate risk <strong>of</strong> <strong>of</strong>fendingin early adolescence peaking around the age <strong>of</strong> 13 years and declining to a lower riskaround the age <strong>of</strong> 17 years onward. This group reported a mean <strong>of</strong> 4.8 <strong>of</strong>fences overthe period from 14 to 20 years.The intermediate onset trajectory group, mostly did not display any conduct problems.This group had a similar <strong>of</strong>fending pr<strong>of</strong>ile to the early onset group, but started <strong>of</strong>fendingduring mid-childhood. This group had a very clear peak <strong>of</strong> <strong>of</strong>fending between the years14 to 17, with a peak risk <strong>of</strong> 91% occurring at the age <strong>of</strong> 17. This group had a muchgreater rate <strong>of</strong> <strong>of</strong>fending overall with a mean <strong>of</strong> 48.8 <strong>of</strong>fences reported between theages <strong>of</strong> 14 and 20.The late onset trajectory group had a relatively low rate <strong>of</strong> conduct problems (12%) andhad an <strong>of</strong>fending pr<strong>of</strong>ile with low risk prior to 17 years <strong>of</strong> age, that increased toapproximately 85% at 17 years and declined thereafter. This group had an <strong>of</strong>fendingrate that was less than the intermediate but greater than the first two, with a mean rate<strong>of</strong> 24.1 <strong>of</strong>fences.The chronic <strong>of</strong>fender trajectory group had a majority <strong>of</strong> people with conduct disorder(58%). High rates <strong>of</strong> <strong>of</strong>fending were observed between 11 to 17 years with a smalldecline at 20 years <strong>of</strong> age. This group had a dramatically higher <strong>of</strong>fending rate, withmembers reporting an average <strong>of</strong> 141.1 <strong>of</strong>fences between the age <strong>of</strong> 14 and 20 years(35.3 <strong>of</strong>fences per annum).Overall, Fergusson and Horwood (2002) found that increasing criminal tendencies wereassociated with male gender, parental criminality, parental conflict, tendencies to noveltyseekingbehaviours, low intelligence and low self esteem. Figure 2-5 shows the associationsbetween sub-types <strong>of</strong> adolescent-limited <strong>of</strong>fenders to FF risk factors. These increased withthe rate <strong>of</strong> <strong>of</strong>fending, except for late onset <strong>of</strong>fenders, who were more likely to be influencedby their peers and/or low self esteem.23
