Momentarily narcissistic? Development of a short, state version of the Pathological Narcissism Inventory applicable in momentary assessment

Abstract

BackgroundNarcissism viewed as a personality process rather than a stable trait explains narcissistic functioning as a tool for maintaining a positive self-view. Studying narcissism therefore needs adequate momentary measures for collecting higher frequency longitudinal data in experience sampling method (ESM) studies. In this study, a shorter version of the Pathological Narcisissm Inventory is offered to measure vulnerable and grandiose narcissistic states, applicable in momentary assessment.MethodsThe measurement tool was tested in three samples. First, we assessed the factor structure and associations with other contemporary measures of narcissism in a cross-sectional design on one English speaking (n = 319) and one Hungarian sample (n = 236). Second, we conducted a five-day long experience sampling method study with a total of 15 measurement points (n = 123).ResultsBased on structural equation modelling and multilevel analyses, the results suggest that the measure has adequate psychometric properties in both the within and between subject levels as well as acceptable convergent and discriminant validity.ConclusionsThe Pathological Narcissism Inventory – State Version (PNI-S) can be a useful tool in momentary data collection enabling the examination of personality processes behind narcissistic functioning.

Psychoeducation for Pathologic Narcissism and Narcissistic Personality Disorder: A Review and Proposal for a Good Psychiatric Management-based Six-week Group Program

“…The first part of the session (30 min) would be focused on promoting a shared reflection on the patients’ weekly experiences regarding their symptoms. Each session would start with the completion of a brief self-questionnaire evaluating the intensity of the symptoms of narcissism over the last week, the Pathological Narcissism Inventory (PNI)-State Questionnaire, 38 followed by a round-table discussion of participants’ PN/NPD-related difficulties that took place since the last session. Indeed, patients would be encouraged at the end of each session to take notice of such situations between sessions, so they can share and work through those same experiences in the next group session.…”
