Abstract

AbstractObjectiveThe aim of this study is to investigate the characteristics of ‘not just right experiences’ (NJREs) in patients with obsessive–compulsive disorder (OCD), anxiety disorders (ADs) or major depressive disorder (MDD), compared with those of healthy controls (HCs).MethodOne hundred adults with OCD, 86 adults with ADs, 57 adults with MDD and 60 HCs were enrolled in the study. The Not Just Right Experiences Questionnaire Revised (NJRE‐QR), Yale–Brown Obsessive–Compulsive Scale (Y‐BOCS), Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI) were used to evaluate clinical symptoms in patients with OCD, ADs or MDD. The Obsessive Belief Questionnaire‐44 (OBQ‐44) was used to evaluate OC beliefs in the OCD patients. The HCs only received assessment using the NJRE‐QR. Analysis of variance (ANOVA) and covariance (ANCOVA) were performed to compare the NJREs scores across the groups, while Pearson correlation and partial correlation analyses were used to examine the association between NJREs and other clinical features. The contribution of NJREs to predict OC symptoms was determined by multiple stratified linear regression.ResultsIndividuals with OCD had significantly higher scores for the number of NJREs than ADs, but not MDD. The severity of NJREs was also significantly higher in patients with OCD than those with MDD or ADs (F = 5.23 and F = 19.79, respectively, P < 0.01). All the clinical scores in the NJRE‐QR were significantly higher than those in the HC group. The number and severity of NJREs correlated significantly with the Y‐BOCS total score (r = 0.29 and r = 0.39, respectively, P < 0.01). NJREs showed an independent contribution to OC symptoms, which alone explained 8% of the variation (F = 16.49, ΔR2 = 0.08; P < 0.01).ConclusionNJREs are related closely to OC symptoms, with their severity discriminating between OCD patients and those with ADs or MDD. NJREs were more specific for OCD in the Chinese population and are therefore worthy of further study in the future.
