Which behavior is commonly associated with obsessive-compulsive personality disorder?

Inflexibility regarding personal rules is a hallmark characteristic of obsessive-compulsive personality disorder (OCPD). Individuals with this disorder often exhibit a strong need for order, perfectionism, and control over their environment. They may adhere rigidly to their own set of rules or standards, which can lead to difficulties in adapting to change or accepting different perspectives. This inflexibility is tied to their desire for predictability and structure in their lives, making them resistant to new ideas or approaches that diverge from their established norms.

The other behaviors mentioned, such as being overly submissive in relationships, making impulsive decisions, or being sensitive to social rejection, are more characteristic of different personality disorders or psychological conditions. For example, impulsive decision-making may relate more to borderline or personality disorders, while sensitivity to social rejection is often associated with avoidant personality traits or social anxiety disorder. The key focus in OCPD, however, remains the individual's rigid adherence to their personal rules and standards, which underscores the correct identification of inflexibility as a defining behavior of the disorder.
