Offenders with untreated mental illness have a higher recidivism rate and a greater number of criminogenic risk factors than those without mental illness. Previous research has demonstrated that the likelihood of appetitive aggression increases in violent contexts where individuals perpetrate aggressive acts. Using the Ecological Systems Theory, this study investigated the association between mental health disorders and recidivism among incarcerated adult offenders in South Africa, and the intervening role of appetitive aggression and substance use. Using a cross-sectional quantitative research design, a sample of 280 incarcerated male and female adult offenders aged 18\u201335 with no known psychiatric disorders were sampled at a correctional facility in South Africa. The re-incarceration rate, mental health disorders, substance use, and appetitive aggression symptomology were assessed using the Hopkins symptoms checklist, the CRAFFT measure of substance use, and the appetitive aggression scale. Findings indicate a 32.4% recidivism rate (n = 82). Cluster analysis indicated that the combination of anxiety, depression, substance use, and appetitive aggression increased the likelihood of recidivism. Appetitive aggression median differences between clusters 2 and 3 played a key role in distinguishing recidivism risk among recidivist and non-recidivist participants. Chi-square analysis highlighted group differences in education levels among the established clusters [<jats:italic>x<\/jats:italic><jats:sup>2<\/jats:sup>(3, n = 217) = 12.832, p = .005, which is &lt; .05] as well as group differences in the type of criminal offence [<jats:italic>x<\/jats:italic><jats:sup>2<\/jats:sup>(3, n = 187) = 24.362, p = .000, which is &lt; .05] and cluster membership. Combined factors that increase the likelihood of recidivism provide a typology for classifying offenders based on particular recidivism risk determinants, which offers insights for developing tailored interventions that address a combination of factors.<\/jats:p>","DOI":"10.1371\/journal.pone.0278194","type":"journal-article","created":{"date-parts":[[2023,1,19]],"date-time":"2023-01-19T18:26:29Z","timestamp":1674152789000},"page":"e0278194","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":12,"title":["Mental health disorders and recidivism among incarcerated adult offenders in a correctional facility in South Africa: A cluster analysis"],"prefix":"10.1371","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7274-6408","authenticated-orcid":true,"given":"Kwanele","family":"Shishane","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Johannes","family":"John-Langba","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eyitayo","family":"Onifade","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2023,1,19]]},"reference":[{"key":"pone.0278194.ref001","doi-asserted-by":"crossref","first-page":"145","DOI":"10.30958\/ajss.1-2-5","article-title":"A Need to Re-integrate Prisoners to the Community: A Case of Polokwane Medium B Prison, South Africa","volume":"1","author":"M.
