Abstract
Introduction
Suicidal thoughts are highly prevalent among individuals with psychotic disorders and individuals at risk for psychosis. Although a growing body of literature demonstrates that this risk is greatest during the earliest stage of psychotic illness, few studies have directly compared rates of suicidal thoughts and behaviours across stages of illness.
Methods
The current study addressed this gap by using a retrospective chart review to compare rates of past 2-week suicidal thoughts and past year suicidal behaviour across individuals at clinical high risk for psychosis (CHR-P; n = 50), first-episode psychosis (FEP; n = 84) and longstanding psychosis (LP; n = 59). Chi-squared analyses were used to compare groups on past two-week suicidal thoughts and past year suicidal behaviour. Frequencies of the various methods for suicidal behaviour were computed across the entire sample and within each group.
Results
Results indicate that individuals at CHR-P had the highest rate of past two-week suicidal thoughts compared to FEP and LP. The most common method for suicidal behaviour in all groups was overdose.
Conclusion
These findings suggest that CHR-P is a particularly vulnerable period for suicide risk and highlight the continued need for research and resources for this population. These findings also underscore the importance of careful monitoring of medication use and efforts to reduce the risk of overdose.
期刊介绍:
Early Intervention in Psychiatry publishes original research articles and reviews dealing with the early recognition, diagnosis and treatment across the full range of mental and substance use disorders, as well as the underlying epidemiological, biological, psychological and social mechanisms that influence the onset and early course of these disorders. The journal provides comprehensive coverage of early intervention for the full range of psychiatric disorders and mental health problems, including schizophrenia and other psychoses, mood and anxiety disorders, substance use disorders, eating disorders and personality disorders. Papers in any of the following fields are considered: diagnostic issues, psychopathology, clinical epidemiology, biological mechanisms, treatments and other forms of intervention, clinical trials, health services and economic research and mental health policy. Special features are also published, including hypotheses, controversies and snapshots of innovative service models.
