Background
The Narcissistic Personality Inventory (NPI-40) is one of the most widely used self-report measures of narcissistic personality traits in non-clinical populations. The assessment measures traits associated with grandiosity, entitlement, authority, superiority, self-admiration, and interpersonal dominance. The NPI-40 is based on a dimensional understanding of narcissistic traits rather than a clinical diagnosis of Narcissistic Personality Disorder (NPD). Many individuals may display certain narcissistic characteristics without meeting the criteria for a personality disorder. The assessment is frequently used in psychological research, personality studies, and self-reflection contexts to explore patterns of confidence, leadership, self-image, social influence, and attention-seeking behavior.
Procedure
Read each pair of statements carefully and select the statement that best describes you. There are no right or wrong answers. Choose the option that feels most accurate to your personality and typical behavior.
Participation
This assessment is intended for educational and self-reflection purposes only and does not provide a clinical diagnosis. Results should be interpreted within the broader context of personality and behavior.
Scoring & Interpretation
The NPI-40 is scored using a binary forced-choice format. Each response scores 1 point for selecting the narcissistic statement and 0 points for selecting the non-narcissistic statement. Total raw scores are calculated by summing all responses, with the total score ranging from 0 to 40. Higher scores represent a greater concentration of narcissistic personality traits. Scores are distributed across six distinct sub-scales (Authority, Superiority, Exhibitionism, Manipulativeness, Self-Sufficiency, and Entitlement), which are standardized to a 0–100 scale for comparative profiling.
