ABSTRACT Objective Obsessive-compulsive disorder (OCD) is a clinically heterogeneous condition with a variety of symptom dimensions. The aim of this study was to assess the ability of university students and the lay public to identify a lesser-known theme of obsessive-compulsive symptoms known as relationship obsessive-compulsive disorder (ROCD) and to examine factors that impact identification and stigma of this symptom subtype. Method A total of 258 participants (M = 24.1 years, SD = 7.61) completed an online survey. A series of clinical vignettes depicted hypothetical characters with ROCD, varied by symptom presentation (partner-focused, relationship-centred) and gender (female, male), as well as a contamination OCD vignette for comparison purposes. Results As expected, participants showed significantly higher misidentification rates for ROCD (88.3%) compared to the contamination vignettes (28.7%). ROCD was most often misidentified as relationship issues and worry. Although partner-focused ROCD was not misidentified more frequently than relationship-centred ROCD, partner-focused vignettes were significantly more stigmatised than relationship-centred vignettes as predicted (with the male, partner-focused vignette most stigmatised). Conclusions High levels of misidentification of ROCD may contribute to the existing lag between OCD symptom onset and proper treatment, emphasising the need for greater education and media focus on the heterogeneity of OCD.
