However, recidivism rates may be down to societal problems such as poverty and lack of support for mental health which will mean recidivism remains high if this is not addressed.
Also there’s lack of research into societal factors that affect recidivism as most are centred around prison and not post release environments and people may be more inclined to reoffend should they go into a pro-crime environment.
Therefore more emphasis need to be put on post release factors before you can determine any cause and effect for psychological effects on recidivism.
