Previous research has linked changes in family structure (especially parental divorce) with involvement in juvenile delinquency. Comparatively less research has attempted to examine the long-term impact of shifts in family structure on delinquent and criminal involvement. The current study addresses this gap in the literature by examining the influence of changes in family structure during adolescence on delinquent involvement both cross sectionally and longitudinally. Our findings revealed a small and only temporary association between changes in family structure and adolescent delinquency. We discuss the implications of these results for future research.
