A sample of 339 young adults completed the Polish version of the Hypersensitive Narcissism Scale, the Narcissistic Personality Inventory, and two subscales of the Wisconsin Schizotypy Scales - Short Form: the Revised Social Anhedonia Scale and the Physical Anhedonia Scale. We found a positive correlation between social anhedonia and vulnerable narcissism, and a negative correlation between social anhedonia and grandiose narcissism.

Vulnerable narcissistic personality is associated with social deficits, namely social anhedonia. Future research could investigate the relationship between vulnerable narcissism and schizotypy to establish whether vulnerable personality is a risk factor for developing serious mental illnesses.
