Suicidality in obsessive compulsive disorder (OCD): a systematic review and meta-analysis

Area of Science:

• Psychiatry
• Clinical Psychology
• Mental Health Research

Background:

• Suicidality in obsessive compulsive disorder (OCD) is debated.
• Previous research lacks a comprehensive synthesis of the association between OCD and suicidality.
• Understanding psychological mechanisms underlying suicidality in OCD is crucial.

Purpose of the Study:

• To systematically review the association between suicidality and OCD.
• To identify psychological factors contributing to suicidality in individuals with OCD.
• To provide evidence-based insights for clinical practice and future research.

Main Methods:

• Systematic review of five electronic databases (Medline, PsycINFO, Embase, Web of Science, CINAHL) up to April 2014.
• Meta-analysis using random effects models.
• Inclusion of 48 studies and 30 independent comparisons.

Main Results:

• A moderate to high, significant association between suicidality and OCD was found (Hedges' g=0.66).
• This association persisted across suicidal ideation and suicide attempts.
• Comorbid disorders, symptom severity (obsessions, depression, anxiety), hopelessness, and prior attempts were linked to increased suicidality.

Conclusions:

• Suicidality is a significant concern in individuals with OCD.
• Comorbid conditions and symptom severity are key risk factors.
• Further research with higher methodological quality is needed to inform clinical interventions for reducing suicide risk in OCD.
