518Trajectories of offending in people with psychotic illness and other mental disorders: a population study

Background Trajectory analysis has been used to study long-term patterns of offending and identify offending groups. Only few studies have explored patterns in people with psychotic illness and these were restricted to adult offenders. This study examines offending trajectories, and identifies risk factors, for people aged 10-26 with psychotic illness (PI) and other mental disorders (OMD) compared to those with no mental disorders (NMD). Methods This is a whole-population record-linkage study of 184,147 people born in Western Australia (WA) 1983-1991 using data from WA psychiatric case register, WA corrective services and other state-wide registers. Group-based trajectory modelling was used to identify offending trajectories. Results Four offender groups were identified for each mental health status (MHS) group: MHS groups had similar offending patterns, however PI had a lower proportion of individuals in the G1 group and later offending onset in the G3 group. Gender, indigenous status, substance use, childhood victimisation and parental offending were risk factors associated with group membership; for PI, childhood victimisation and parental offending were only significant in the G4 group. Conclusions Overall offending patterns and risk factors were similar for all MHS groups, however, some differences were observed for PI. Key messages To reduce offending in this population, interventions need to occur at an early age.

Criminal predictors and protective factors in a sample of young offenders : relationship to offending trajectories

Although the predictors of delinquency are well-documented in the psychological and criminological literature, an understanding of their relationship with longitudinal criminality in an offender sample has not been achieved. The purpose of this thesis was to examine the relationship between childhood and adolescent criminal predictors and protective factors and the four criminal trajectories identified by Day et al. (2008). Results revealed differences in predictor items among the trajectory groups within the individual, family and peer domains during childhood and adolescence. A backward stepwise procedure found that the following childhood variables, broken home and involvement with alternative care. Identifying the factors influencing the onset and maintenance of criminality can inform prevention and intervention programs that target antisocial and delinquent behaviour.

Early-career offending trajectories among outlaw motorcycle gang members

This study examines the criminal histories of outlaw motorcycle gang (OMCG) members during adolescence and early adulthood to determine whether the profile of young members has changed over time. The recorded offence histories of three cohorts of members—those born between 1979 and 1983, 1984 and 1988, and 1989 and 1993—were compared. Seventy-eight percent of OMCG members across all three cohorts had at least one recorded offence between the ages of 12 and 24. The majority of offenders did not desist but continued offending at a steady rate into adulthood. The youngest cohort in the study was more likely than the middle and older cohorts to have a criminal history and follow a high-rate offending trajectory. Members of the youngest cohort were also more likely to have been apprehended for violence and intimidation, weapons and ongoing criminal enterprise offences by their early twenties. These results suggest that OMCGs are recruiting younger members, who are becoming involved in gang-related offending earlier in life, or that individuals with a history of offending are becoming more likely to join or be recruited into OMCGs.

Developmental Offending Patterns: Female Offending Beyond the Reference Category

Compared with young men, justice-involved young women are often characterized by a greater array of risk factors, yet show a more limited pattern of offending. This paradox may be related to risk factors functioning differently not only for male versus female adolescents but also among female adolescents involved in offending. Data were used on 284 girls from the Incarcerated Serious and Violent Young Offender Study to address whether risk factors varied across different offending trajectories modeled between ages 12 and 23. Risk factors measured from self-report interviews were compared across the three trajectories identified. Individual, family, and school risk factors varied across trajectory groups, but not always in ways anticipated. Female offending does not appear to fit neatly within existing developmental criminology theory. Theoretical models should be adapted, or new models developed, to account for the complexities of female offending patterns.

Politics, Social and Economic Change, and Crime: Exploring the Impact of Contextual Effects on Offending Trajectories

Do government policies increase the likelihood that some citizens will become persistent criminals? Using criminological concepts such as the idea of a “criminal career” and sociological concepts such as the life course, this article assesses the outcome of macro-level economic policies on individuals’ engagement in crime. Few studies in political science, sociology, or criminology directly link macroeconomic policies to individual offending. Employing individual-level longitudinal data, this article tracks a sample of Britons born in 1970 from childhood to adulthood and examines their offending trajectories through the early 1980s to see the effects of economic policies on individuals’ repeated offending. A model is developed with data from the British 1970 Birth Cohort Study that incorporates individuals, families, and schools and takes account of national-level economic policies (driven by New Right political ideas). Findings suggest that economic restructuring was a key causal factor in offending during the period. Criminologists are encouraged to draw on ideas from political science to help explain offending careers and show how political choices in the management of the economy encourage individual-level responses.

Saints and Sinners

This chapter draws upon qualitative and quantitative data to assess the extent of both victimization and offending in the market place. It examines what consumers did when they found they had been cheated, and discusses the extent to which there is an overlap between being a victim and offender. The chapter paints a detailed picture of victimization, offending, and the degree to which these are related. Findings show that some types of victimization are very common in all three regions, like e.g. unnecessary repairs, while considerable differences exist between them in terms of being offered too little by one’s insurer (most common in West Germany), or being sold faulty second-hand goods (most common in England and Wales). Differences in offending are by far more distinct, with the West Germans outdoing their East Germans and English and Welsh counterparts. For both victimization and offending trajectories of mostly ‘slow-burning change’ were detected for all three regions. Middle-class consumers do not differ from disadvantaged social groups with regard to the relation between victimization and offending: the findings suggest as strong a relationship between victimization and offending, similar to what is usually found for violent offenders and their victimization in marginalized neighbourhoods.
