| Summary: | This study uses latent class analysis and latent transition analysis to model and compare patterns of offending over time for males and females by: (1) identifying qualitative dimensions of offending; (2) modeling how patterns of offending change over time; and (3) exploring factors related to patterns of offending. This is a secondary analysis of data from the Edinburgh Study of Youth Transition and Crime, a longitudinal study consisting of a cohort of about 4,000 young people from secondary schools in the City of Edinburgh who responded to questionnaires administered between 1988 and 2001, when they were about 12, 13, 14, and 15 years old.
Previous studies of offending have used trajectory modeling to explore the course of offending from onset to termination, but the models are generally based on a count of types of offences aggregated across individuals over time, making it difficult to determine whether individuals exhibit more versatility or specialization in offending or switch offences from one point in time to another. In addition, most of the studies on patterns of offending have focused primarily on males. An understanding of patterns of offending over time for both males and females is important for the design and selection of developmentally appropriate prevention/treatment strategies.
The present study adds to the literature by (1) further exploring the small and understudied literature on offence transitions; (2) examining more closely the development of female offending separately from and in relation to male offending; and (3) exploring a range of factors (criminogenic and non-criminogenic) related to the development of offending for both males and females. While the same number of qualitative dimensions (latent classes) characterised male and female offending in this study, there were some structural differences. There was also evidence of shifts in the qualitative dimensions for males and females over time. Finally, those factors classified as criminogenic were more likely to differentiate among the latent classes than those classified as non-criminogenic.
