Farrington (2006) The Cambridge Study
Aims: To document the start, duration and end of offending behaviour from childhood to adulthood in families.
Design: Prospective, longitudinal survey. Interviews and criminal record searches.
Participants: 411 East London boys aged 8/9, predominantly white working class.
- 91% of those convicted at age 10-13 were reconvicted
- Most crimes committed by youths aged 17
- A small proportion (7%) of males were 'chronic offenders' who accounted for about half of all recorded crimes. More likely to have a convicted parent, delinquent sibling, high daring, young mother, low popularity, disrupted family and large family size.
- 93% had commited a crime at some stage even though they were not reported to the police.
- At age 48, 161 had official convictions
- The number of men leading successful lives (6/9 of the criteria of life success) increased with age.
Conclusion: Early prevention could have wide-ranging benefits.
