One in Three Young Offenders in Northern Russia Has Psychotic-Like Experiences — and They Predict Suicide Risk
- 31.6% of incarcerated male adolescents in Northern Russia had lifetime psychotic-like experiences (PLEs) — assessed by K-SADS-PL semi-structured interviews with 370 young offenders aged 14–19
- PLEs significantly predicted suicidal thoughts and behaviors (STBs) even after controlling for psychiatric comorbidities (OR = 1.79) — PLEs are an independent risk factor, not just a symptom proxy
- PLEs also predicted non-suicidal self-injury (NSSI) with even stronger association (OR = 2.02) — the signal holds across self-destructive behaviors
- This is the first study examining PLEs-STBs association in incarcerated youth — a population with known elevated rates of both phenomena
The intersection of psychotic-like experiences and suicidality in juvenile offenders is a clinical blind spot. We know these adolescents have high rates of both. What we have not known — until this collaborative study between Sechenov Moscow Medical University, Uppsala University, and the Arctic University of Norway — is whether PLEs independently predict suicidality in this population. They do.
What PLEs are and why they matter here
Psychotic-like experiences are not psychosis. They include transient hallucination-like perceptions, paranoid thinking, and magical ideation. In the general adolescent population, PLEs are relatively common (5–15%) and usually benign. In incarcerated youth, the prevalence reaches 31.6% — and the clinical meaning shifts. In this context, PLEs signal disturbed information processing under conditions of chronic stress, trauma exposure, and social deprivation. They mark a brain under siege.
The study's strength is its assessment method: the K-SADS-PL (Schedule for Affective Disorders and Schizophrenia for School-Age Children) administered as a semi-structured clinical interview — not a self-report questionnaire. This reduces the noise that self-report introduces in populations with limited introspective vocabulary.
The clinical implication
The independent prediction of STBs (OR = 1.79) after controlling for psychiatric diagnoses means that PLEs are not just a downstream symptom of depression, conduct disorder, or substance use — all of which are prevalent in this population. PLEs add information that standard diagnostic categories miss. An adolescent offender who endorses hearing voices that are not there, or believing others can read their thoughts, is at elevated suicide risk — over and above whatever diagnostic labels they carry.
For your practice
For clinicians working in juvenile justice, forensic adolescent psychiatry, or detention facility mental health: screen for PLEs during routine assessment. The K-SADS-PL is comprehensive but time-intensive; shorter screens (PRIME Screen, PQ-16) can flag who needs fuller evaluation. When PLEs are present: do not dismiss them as "normal adolescent experiences" in this population. They signal vulnerability. Combine PLE assessment with suicide risk evaluation — the two are not separate clinical domains in incarcerated youth.
In incarcerated adolescents, psychotic-like experiences are not curiosities. They are suicide risk markers that standard diagnostic categories miss.
Cross-sectional design — cannot establish causation. Male-only sample. Northern Russia-specific institutional context may limit generalizability. K-SADS-PL assesses lifetime PLEs, not current. No control group of non-incarcerated youth.
