Perfectionistic tendencies refer to a personality trait characterized by the relentless pursuit of flawlessness, high standards, and critical self-evaluations. This trait often leads individuals to set excessively high expectations for themselves and others, resulting in significant stress and dissatisfaction. In the context of Cluster C personality disorders, particularly Obsessive-Compulsive Personality Disorder (OCPD), these tendencies are linked with rigid thinking patterns and difficulties in adapting to change or accepting mistakes.
