Chapter 5 represents a quantitative analysis of criminal recidivism and related factors based on criminal records. It delves into the basic results, beginning with descriptive statistics on individual factors, encompassing treatment-related elements, general correctional markers, and psychosocial components anticipated to influence recidivism. The chapter further explores the relationships between different predictors and forms of reoffending across varying groups of study participants and offenders, utilizing regression models and factor analyses. Additionally, a comparative analysis is conducted with a sample of prison inmates who were not part of the quasi-experimental longitudinal study. Moreover, the chapter presents findings from the self-reported delinquency questionnaire completed by participants during the post-release study phase, offering additional insights into recidivism trends.
