• Obsessive-Compulsive Disorder (OCD): OCPD lacks true obsessions and compulsions that are distressing and ego-dystonic.
• Hoarding Disorder: If hoarding is extreme, consider hoarding disorder.
• Narcissistic PD: Both may involve perfectionism, but narcissists believe they have achieved it; OCPD individuals are self-critical.
• Antisocial or Narcissistic PDs: May also be ungenerous, but still indulge themselves—unlike the frugality of OCPD.
• Schizoid PD: Social detachment in OCPD is from discomfort with emotions and overwork, not a fundamental lack of interest in intimacy.
• Medical Conditions or Substance Use Disorders: Must rule out personality change due to a medical condition or substances.
