T his special issue on empirical investigations of strengths and desistance from criminal offending, consists of 11 articles-eight quantitative and three qualitative investigations. The first four studies, all quantitative, are focused on desistance in adolescence. In the fifth contribution, findings are reported for both adolescent and adult samples, making it a transition point in the issue. The focus of the six articles that follow is on desistance in adulthood. Two core features of the literature can be seen. The first, which serves as a segue to comments on the three qualitative studies, concerns the two broad approaches to desistance from crime into which the research can be categorized. The second feature is the range of effects that strengths can be shown to have, about which some thoughts are offered in the concluding comments of this introduction. The first feature of the literature is the operationalization of desistance, in broad terms, as either a dichotomous variable (an event or absence of an event; as it relates to this special issue, a new criminal offense or no new criminal offense at follow-up for an individual member of a group, all of whom, by virtue of inclusion in the group, have at least one known criminal offense) or as a process by which the individual's desistance from criminal involvement unfolds over time (Bushway et al., 2001; Kazemian, 2016; Maruna, 2001).

Kelly and Ward's (this issue) article, intended to add to the literature on gang disengagement in the US and authoritative work by Carson, Decker, Pyrooz, Rosen, and others introduces a resilience framework (Masten, 2016) to this area. They conducted a thematic narrative analysis with
