Self-regulatory and narcissistic grandiosity and vulnerability: Common and discriminant relations

In three studies we examined the unique relations of narcissistic grandiosity and vulnerability with the self-regulatory factors of promotion, prevention, assessment, and locomotion. We found that grandiosity has unique positive relations with promotion, assessment, and locomotion but is unrelated to prevention (Study 1). We also found that vulnerability has a unique positive relation with assessment, a unique negative one with promotion, and is unrelated to locomotion and prevention (Study 2). Study 3 replicated these findings and demonstrated that they do not derive from the self-regulatory factors' or grandiosity and vulnerability's associations with self-esteem. The results indicate that grandiosity and vulnerability have self-regulatory underpinnings and provide evidence of their specific discriminant nature. Further, they indicate that the critical evaluations associated with strong assessment concerns are a significant vulnerability for both narcissism presentations.
