Validity and reliability of the super brief-pathological narcissism inventory in Chinese college students / 中华行为医学与脑科学杂志

ABSTRACT

Objective:To test the psychometric properties of the super brief-pathological narcissism inventory(SB-PNI) in Chinese college students.Methods:A total of 541 college students were recruited through convenient sampling method.All subjects were measured by SB-PNI, fear of missing out scale(FOMOs), Interpersonal Communication Scale and Social Interaction Scale.SPSS 25.0 was used for item analysis, criterion related validity analysis and Cronbach α coefficient. Mplus 7.4 software was used for structural validity analysis.Results:Through the construct validity analysis, it was found that the Bi-factor model was well fitted.SB-PNI presented a better Bi-factor structure(χ 2/ df=2.03, CFI =0.96, TLI=0.94, RMSEA=0.04, SRMR=0.04), namely a general factor and two local factors (grandiose narcissism and vulnerable narcissism). The score of SB-PNI was positively correlated with grandiose narcissism, vulnerable narcissism, interpersonal communication, social interaction and fear of missing out ( r=0.13-0.85, all P<0.01). The Cronbach's α coefficients of SB-PNI degreed from 0.74 to 0.81.The composite reliability of SB-PNI degreed from 0.75 to 0.84.The retest reliability of SB-PNI degreed from 0.75 to 0.85.The homogeneity reliability of SB-PNI was 0.64. Conclusion:The Chinese version of the SB-PNI has good validity and reliability among Chinese college students.
