Abstract
Background
Obsessive-compulsive disorder (OCD) is a condition with poor treatment outcomes. Improved understanding of the aetiology can inform prevention and treatment approaches; hence several studies have assessed early maladaptive schemas (EMSs) in OCD. This systematic review and meta-analysis aimed to synthesise the evidence on relationships between the 18 EMSs and OCD.
Methods
The study was conducted according to PRISMA guidelines and registered on PROSPERO (CRD42022329337). A systematic search of PubMed, PsycINFO, and CINAHL Complete was conducted on 4 June 2022. Studies in peer-reviewed journal articles were included if they assessed EMSs and OCD (diagnosis or symptom severity) in adults with a mean age of 18 years or older. Studies were excluded if they were not in English, did not include original quantitative data, or reported on case studies. Study details were tabulated and the meta-analysis findings were presented using forest plots. Methodological quality was assessed using the Appraisal tool for Cross-Sectional Studies (AXIS).
Results
Based on 22 studies (pooled N = 3699), all 18 EMSs were positively correlated with OCD. The largest associations were with the dependence/incompetence (r = 0.40 95 % CI [0.32, 0.47]), vulnerability to harm or illness (r = 0.40 95 % CI [0.32, 0.48]), and negativity/pessimism schemas (r = 0.42 95 % CI [0.22, 0.58]).
Limitations
Several meta-analyses showed considerable heterogeneity and publication bias.
Conclusions
The findings suggest all EMSs, particularly those relating to disproportionate negative expectations and a perceived inability to cope, are implicated in OCD. Psychological prevention and treatment for OCD may benefit from targeting these schemas.
