The latent structure of olfactory reference disorder symptoms: A taxometric analysis

Olfactory reference disorder (ORD), a newly included disorder in the ICD-11, is characterized by ‘pathological’ concerns about emitting body odor. While research is emerging on the construct, no study has directly examined the boundary between ORD and normal body odor concerns. That is, should ORD b...

description Olfactory reference disorder (ORD), a newly included disorder in the ICD-11, is characterized by ‘pathological’ concerns about emitting body odor. While research is emerging on the construct, no study has directly examined the boundary between ORD and normal body odor concerns. That is, should ORD be considered as categorical in nature versus a more dimensional construct? As such, the current study explored the extent to which ORD symptoms correspond to a distinct category or dimension in a mixed university student and community sample (n = 757). Three indicators, derived from the Yale-Brown Obsessive Compulsive Scale Modified for Olfactory Reference Syndrome, were submitted to three independent taxometric procedures: MAMBAC, MAXEIG, and L-Mode. Two of three procedures showed that the latent structure of ORD is dimensional rather than categorical. The comparison curve fit index profile method yielded dimensional structure. Results suggested that researchers and clinical practitioners would be well-advised to conceptualize, assess, and treat ORD symptoms in a dimensional way.
