Depressive symptoms induce paranoid symptoms in narcissistic personalities (but not narcissistic symptoms in paranoid personalities).
Based on clinical experience, anecdotal reports, and past empirical and conceptual work, we predicted that when people with narcissistic tendencies experience depressive symptoms, they are prone to develop paranoid attitudes. Moreover, we expected that this process was unidirectional, and that the combination of paranoid tendencies and depressive symptoms would not be associated with an increase in narcissistic symptoms. In both cases, results from our 6-month longitudinal study of 71 previously suicidal adults conformed to our expectations.
