The Hypersensitive Narcissism Scale (HSNS) is a self-report measure of covert narcissism.
It was developed by Holly M. Hendin and Jonathan M. Cheek in 1997.
[1] It consists of ten items rated on a five-point scale.
It has a near zero correlation with the Narcissistic Personality Inventory, which measures overt narcissism.
[1] The unidimensionality of the HSNS has been questioned.
