Validation of the Super-Brief Pathological Narcissism Inventory (SB-PNI) among Swedish adolescents

• This study examines the psychometric structure and properties of the Swedish version of the Super-Brief Pathological Narcissism Inventory (SB-PNI) among adolescents. In order to ensure the validity and feasibility of the measure, we examined the factor structure, measurement invariance across gender, age and ethnicity, and construct validity in relation to a number of correlates of narcissism in adolescence. Data were drawn from a large cross-sectional survey conducted in 35 schools in southern Sweden. The sample consisted of N = 5313 adolescents (Mage = 16.10 SD = 1.55) with 52.2% girls, 45.9% boys and 1.8% adolescents with unspecified gender, from compulsory and upper secondary schools in southern Sweden. The results showed that the measure holds a two-factor structure, suggesting the use of the subscales grandiosity and vulnerability separately, rather than as a unidimensional measure. The correlated factors grandiosity and vulnerability yielded full configural and metric invariance across gender, age, and ethnicity. Both grandiosity and vulnerability were correlated with externalizing and internalizing symptoms, as well as with low self-esteem. The study provides evidence for the utility of the SB-PNI among Swedish adolescents and indicates that the measure can be used across male and female adolescents of different ages and ethnic groups.
