Impact of personality pathology on psychosocial functioning.

Personality disorders impair social, occupational, leisure, and global functioning more than a significant disorder such as major depressive disorder. Impairment is found in clinical and community populations. Impairment is independent of co-occurring other mental disorders. Impairment is more stable over time than are the diagnoses themselves. Personality traits are also impairing and may be more predictive of outcomes over time, but a hybrid of personality disorder features and normal range personality traits may be the most predictive model. A general, 'transdiagnostic,' self-other severity factor may be important for understanding the relationship of personality pathology and psychosocial functioning over time. The Alternative DSM-5 Model for Personality Disorders may be useful for the study of psychosocial functioning in individuals with personality pathology.
