Suicide Behaviors among Patients with Substance-Induced Psychosis: A Scoping Review.

Substance-induced psychosis (SIP) is a prevalent psychotic disorder among patients with substance use disorders. SIP implies clinical severity, including suicidal behaviors. To date, few studies have focused on suicidal behaviors among patients with SIP. This study aimed to perform a scoping review to summarize the current findings on suicidal behaviors in patients with SIP and outline the implications for clinical practice. A scoping review was conducted using the most relevant published information on suicidal behaviors among SIP, sourced from two databases. The 19 reviewed articles reported a high prevalence of suicidal behaviors among SIP. Specifically, the prevalence of suicidal ideation ranges from 14.5% to 68%, while suicide attempts vary between 10.5% and 48% depending on the timeframe, setting, and assessment methods used. Several clinical factors such as levels of depression, lifetime trauma, comorbidities, and the substance responsible for inducing psychosis are associated with suicidal behaviors in this population. However, significant knowledge gaps persist, warranting further investigation. Suicidal behaviors are common among patients with SIP and are associated with several clinical factors. However, further investigation is needed to better understand and address suicidal behaviors in patients with SIP.
