Early signs of worry: psychosis risk symptom visual distortions are independently associated with suicidal ideation.

Previous studies have shown an association between suicidal behavior and schizophrenia. However, little is known about this association in those with psychotic experiences and symptoms that do not meet the criteria for full psychosis. The aim of the study was to investigate how psychosis risk symptoms are associated with suicidal ideation. Three-hundred and nine help-seeking adolescents (mean age 15.5 years) who were screened by an early intervention and detection team JERI in Helsinki University Central Hospital, Finland, were interviewed and asked to complete questionnaires of psychosis risk symptoms, suicidal ideation and depression. Psychosis risk symptoms were assessed by self-report and confirmed by interview with questions from PROD-screen, depression was measured with BDI-II questionnaire and suicidal ideation was derived from BDI-II questionnaire. In a logistic regression analysis psychosis risk symptom visual distortions explained independently (OR 4.33; 95% CI 1.28-14.64) suicidal ideation when age, gender, depression and psychosis risk symptoms thought disorders, persecuting feelings and auditory distortions were controlled for. Results suggest that visual distortions are independently associated with suicidal ideation in young people. This finding should be taken into account in assessing help-seeking adolescents.
