= 76). The OCPD measure assessed five OCPD trait dimensions as well as overall OCPD severity. We also included measures of other symptoms (OCD, depression, anxiety, and stress) as well as quality of life. Results revealed that the OCPD group reported heightened IU compared with the community sample, even when controlling for group differences in anxiety, depression, stress, and OCD symptoms. IU was significantly correlated with OCPD trait severity, and regression analyses demonstrated that IU predicted severity of OCPD traits controlling for distress symptoms. Moreover, IU significantly mediated the relationship between OCPD traits and reduced quality of life. These results highlight the importance of considering IU in the context of OCPD, with possible implications for improving treatment. Limitations and future directions for research are discussed.
