“…Regarding physical health, for example, well over half of young adults are either obese or overweight (Ellison-Barnes et al, 2021 ). Adding to a small body of research on possible sources of stunted psychosocial development, such as incarceration (Dmitrieva et al, 2012 ), the present research draws on health-related criminological perspectives (Fahmy & Mitchell, 2022 ; Jackson & Vaughn, 2018 ; Link et al, 2019 ; Link et al, 2020 ; Mallik-Kane & Visher, 2008 ; Wallace & Wang, 2020 ) and multidisciplinary research on psychosocial development, health, and health behaviors (Galambos et al, 2008 ; Kuiper et al, 2018 ; Reysen et al, 2020 ; Westenberg et al, 1999 ; Pailing & Reiners, 2018 ) to examine whether and to what extent poor mental and physical health stall normative development and contribute to persistence in offending among a sample of justice-involved adolescent offenders. We begin by reviewing core ideas in health-based desistance and then explicate their relevance for the development of psychosocial maturity.…”
