This three-level meta-analysis examined associations between dimensions of narcissism and mental health, particularly internalizing psychopathology. It included 229 empirical studies (N = 185,137; k = 735 effect sizes), with findings primarily reflecting self-reported associations. Grandiose narcissism was associated with better positive mental health (r = 0.19, p < 0.001) and was not significantly associated with negative mental health (r = 0.02, p = 0.26). Vulnerable narcissism showed the opposite pattern: lower positive mental health and higher negative mental health. Age, measurement instruments, and construct specificity moderated associations.
Key findings
- Grandiose narcissism was positively associated with positive mental health (r = 0.19, p < 0.001).
- Grandiose narcissism had no significant association with negative mental health (r = 0.02, p = 0.26).
- Vulnerable narcissism was negatively associated with positive mental health (r = -0.25, p < 0.001) and positively associated with negative mental health (r = 0.39, p < 0.001).
- Age, measurement instruments, and construct specificity were significant moderators.
Why it matters
The findings indicate that narcissism is not uniformly related to mental health: associations differ by dimension and by whether mental health is positive or negative. This distinction may help clinicians and researchers avoid treating narcissism as a single construct when interpreting psychological correlates. Because most included studies used self-report measures, the results chiefly describe self-reported associations.
What to keep in mind
Most studies relied on self-report measures, so the findings primarily reflect self-reported associations.
