Previous research in life-course criminology has shown how desistance from crime is linked to the successful transition to adult roles (Sampson and Laub 1993;Uggen 2000). In particular, offenders who establish a stable work history and a strong marriage appear to have better postrelease adjustment than those who have yet to enter such work and family roles. More generally, the transition to adulthood is characterized by the assumption of age-graded roles and the attainment of specific behavioural markers. Completing formal education, obtaining a fulltime job, marrying and voting are all markers signalling adult status, although their sequence and timing may vary over time and space (Shanahan 2000). Specifying the social-psychological process underlying role transition among offenders has therefore emerged as a critical question for theory and empirical research on the desistance process (Shover 1996;Maruna 2001).In this chapter we unite and extend these lines of research in two ways. First, in addition to work and family, we suggest that civic reintegration represents a third important reintegrative domain, one not examined by previous researchers. Following Maruna's contention that desistance is only possible when ex-offenders 'develop a coherent prosocial identity for themselves' (2001: 7), we specify the varieties of civic participation that contribute to such an identity and their subjective meaning to ex-felons. Secondly, building on the work of Matsueda and Heimer (1997), we show how a symbolic interactionist theory of role transition across socioeconomic, familial and civic domains is especially useful in explaining identity shifts over the life course. Although we do not attempt a rigorous empirical test of this theory in this chapter, we
