The Narcissistic Personality Inventory-16 (NPI-16) is a shortened form of the NPI-40 for measuring subclinical narcissism. When situations do not allow the longer 40-item version, this 16-item version is used. The NPI-16 has been shown to have meaningful face, discriminant, internal and predicative validity.
Aligning theoretical framework, gathering articles, synthesizing gaps, articulating a clear methodology and data plan, and writing about the theoretical and practical implications of your research are part of our comprehensive dissertation editing services.

Reliability and Validity
α = .72; mean inter-item correlation = .13; loadings on the first unrotated factor ranged from .13 to .66 with the first factor capturing 19.9 percent of variance; correlated with the NPI-40 at r = .90 (p < .001)
