The Correlation Between Perfectionism and SerumThyroid Hormone Levels in Obsessive-CompulsivePersonality Disorder Patients

Abstract

Objective: Perfectionism is one of the leading clinical symptoms of the obsessive-com pulsive personality disorder (OCPD). This research aimed to compare perfectionism andserum thyroid hormone levels between individuals with OCPD and healthy individuals ofa control group. Methods: The serum levels of free T4, free T3, and thyroid-stimulating hormone of37 patients diagnosed with OCPD and 36 healthy controls with similar sociodemo graphic traits were measured. Furthermore, the Sociodemographic and Clinical DataForm, the Beck Anxiety Inventory (BAI), the Beck Depression Inventory (BDI), and the FrostMultidimensional Perfectionism Scale (FMPS) were applied to all participants in the study. Results: There was a statistically remarkable correlation between the FMPS total score andthe T3 level (r = −0.47, P = .004), and between the BAI and the T3 level (r = −0.41, P = .011). Conclusion: The research findings demonstrated that there could be a correlationbetween perfectionism and thyroid hormone levels.
