Test whether Moffitt’s theory of adolescence-limited offenders, which contends that as young people enter adult roles they exit the "maturity gap" of adolescence and desist from crime, still applies given the changed nature of the early adult years. Examine whether spending time in adult roles remains a driver of desistance, and whether today’s emerging adults are at risk of experiencing a maturity gap between how adult they feel and the reality of their social situation.

Using longitudinal data from a Dutch general population sample aged 18 to 24 years, fixed-effects models were run examining the effect of within-person changes in time spent in adult roles on self-reported delinquency and moderation of this effect by feelings of adultness.

The more time spent in adult roles, the less delinquency respondents consequently reported. This effect was moderated: When spending more time in adult roles and feeling more adult, higher delinquency was reported than when spending more time in adult roles and feeling less adult.

Today’s emerging adults desist from delinquency in response to taking on adult roles. Possible interpretations for the unexpected qualification of this conclusion are discussed, as well as limitations such as the simplicity of our feeling adult measure.
