A comparison of the nomological networks associated with forced-choice and likert formats of the narcissistic personality inventory.
Abstract
The Narcissistic Personality Inventory (NPI) is one of the most popular measures of narcissism. However, its use of a forced-choice response set might negatively affect some of its psychometric properties. The purpose of this research was to compare a Likert version of the NPI, in which only the narcissistic response of each pair was given, to the original NPI, in 3 samples of participants (N = 1,109). To this end, we compared the nomological networks of the forced-choice and Likert formats of the NPI in relation to alternative measures of narcissism, narcissistic personality disorder, entitlement, self-esteem, general personality traits (reported by self and informants), interpersonal styles, and general pathological traits included in the DSM-5. The Likert format NPI-total and subscales-manifested similar construct validity to the original forced-choice format across all criteria with only minor differences that seem to be due mainly to the increased reliability and variability found in the Likert NPI Entitlement/Exploitativeness subscale. These results provide evidence that a version of the NPI that employs a Likert format can justifiably be used in place of the original.

“…power, however, is that narcissists also have many negative interpersonal characteristics, such as a lack of empathy, exploitativeness, a sense of entitlement, antagonism and egocentrism (Sedikides and Campbell, 2017), which could lead them to abuse their power and adversely impact those they lead.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
