Interpersonal problems associated with narcissism among psychiatric outpatients: A replication study .

Results: At baseline, higher levels of narcissism were significantly associated with more interpersonal impairment, particularly characterized by domineering, vindictive, and overly nurturing behaviour. Baseline narcissism was also significantly related to interpersonal impairment at post-therapy. Change in interpersonal difficulties following treatment was not significantly associated with baseline narcissism. Treatment discharge status also was unrelated to narcissism.
