How to Assess Criminal Legal Involvement Risk in First-Episode Psychosis
How should clinicians identify adults with first-episode psychosis who are at higher risk for criminal legal involvement at treatment entry and during early follow-up?
Criminal legal involvement is common during the early course of first-episode psychosis and can interrupt access to specialty care. This guide applies to adults entering treatment for first-episode psychosis when clinicians need a practical way to identify which patients may need closer monitoring for legal involvement and incarceration-related dropout.
-
Ask directly about recent criminal legal involvement
At intake, ask whether the patient has had any arrest, incarceration, or probation or parole in the past month, matching the study's baseline CLI definition. In this sample, 11% reported CLI in the month before treatment entry, and baseline CLI identified a group with substantially higher risk of later CLI.
-
Determine whether untreated psychosis has been prolonged
Estimate duration of untreated psychosis from first psychotic symptoms to treatment entry. In the study, longer DUP, defined as more than 74 weeks, was associated with a higher rate of recent CLI at baseline than shorter DUP, 16% versus 6%.
-
Assess education level
Document whether the patient completed high school. Participants with less than a high school degree were more likely to have recent CLI at baseline than those who completed high school.
-
Screen carefully for substance use disorders and current substance use
Assess lifetime alcohol use disorder, lifetime noncannabis drug use disorder, and whether the patient used alcohol or cannabis in the last 30 days. In multivariable analyses, lifetime alcohol use disorder and lifetime other drug use disorder were unique predictors of baseline CLI, and cannabis use in the month before baseline was the only baseline predictor that remained significant for CLI during follow-up.
-
Rate positive and excitement symptoms at baseline
Assess psychotic symptom severity, particularly positive symptoms and the PANSS excitement factor, which captures hostility, impulsivity, and uncooperativeness. Higher excitement scores were associated with baseline CLI, and higher baseline positive and excitement symptoms were associated with later CLI in analyses controlling for baseline CLI.
-
Use baseline CLI to flag elevated follow-up risk
If recent CLI is present at intake, treat the patient as high risk for recurrent CLI during treatment. In the study, 33% of participants with CLI at baseline had later CLI during follow-up compared with 12% of those without baseline CLI.
Clinical Considerations
- The study did not collect a comprehensive history of criminal legal involvement before enrollment, so this workflow identifies current risk markers rather than full lifetime legal history.
- CLI was measured as past-month arrest, incarceration, and probation or parole at assessments conducted every 3 months, which likely underestimated true legal involvement.
- Charges, convictions, and actual criminal or aggressive behavior were not recorded, so the workflow does not distinguish types or severity of legal events.
- These findings come from adults with nonaffective first-episode psychotic disorders and less than 6 months of antipsychotic exposure, so generalizability outside that population is uncertain.
Bottom Line
At treatment entry for first-episode psychosis, recent CLI, current cannabis or alcohol use, noncannabis drug or alcohol use disorder history, prolonged untreated psychosis, low educational attainment, and elevated excitement symptoms identify patients who warrant closer monitoring for legal involvement.
