Background: In this study, we aimed to investigate the relationship between affective temperament characteristics and obsessive-
compulsive disorder (OCD) symptom dimensions and severity.
Subjects and Methods: 100 patients diagnosed with OCD and 100 healthy controls by random sampling method were included
in the study. SCID-5-CV was administered to all participants. Dimensional Obsessive-Compulsive Scale (DOCS), Temperament
Evaluation of Memphis, Pisa, Paris, San Diego Autoquestionnaire (TEMPS-A), Beck Anxiety (BAI), Depression Inventories (BDI) were
provided to all participants. p<0.05 was taken as statistically significant.
Results: It was found that cyclothymic temperament predicted all OCD symptom dimensions except contamination dimension,
and predicted the OCD severity. Moreover, irritable temperament predicted the OCD symmetry dimension.
Conclusion: In our study, the first study in terms of scrutinizing the relationship between symptom dimensions of OCD and
affective temperament, it was revealed that irritable and cyclothymic temperament significantly predicted the dimensions of OCD, and
cyclothymic temperament was associated with OCD severity. Affective temperaments appear to make a remarkable contribution to
OCD heterogeneity
