Pathological Narcissism Inventory Super Brief

The 12-item pathological narcissism inventory super brief (PNI-SB) was utilized as a shortened measure of grandiose and vulnerable narcissism (Schoenleber et al., 2015). Participants responded on a 6-point Likert scale ranging from “Not At All Like Me” (0) to “Very Much Like Me” (5). The PNI-SB has demonstrated good criterion validity and internal consistency while retaining relevance to current theoretical understanding and literature (Schoenleber et al., 2015), and demonstrated adequate internal consistency for vulnerable (Cronbach’s α = 0.84) and grandiose (Cronbach’s α = 0.76) subscales in the current study.
