Development of a Short Form of the Five-Factor Narcissism Inventory: The FFNI-SF.

Abstract

The Five-Factor Narcissism Inventory (FFNI; Glover, Miller, Lynam, Crego, & Widiger, 2012) is a 148-item self-report inventory of 15 traits designed to assess the basic elements of narcissism from the perspective of a 5-factor model. The FFNI assesses both vulnerable (i.e., cynicism/distrust, need for admiration, reactive anger, and shame) and grandiose (i.e., acclaim seeking, arrogance, authoritativeness, entitlement, exhibitionism, exploitativeness, grandiose fantasies, indifference, lack of empathy, manipulativeness, and thrill seeking) variants of narcissism. The present study reports the development of a short-form version of the FFNI in 4 diverse samples (i.e., 2 undergraduate samples, a sample recruited from MTurk, and a clinical community sample) using item response theory. The validity of the resultant 60-item short form was compared against the validity of the full scale in the 4 samples at both the subscale level and the level of the grandiose and vulnerable composites. Results indicated that the 15 subscales remain relatively reliable, possess a factor structure identical to the structure of the long-form scales, and manifest correlational profiles highly similar to those of the long-form scales in relation to a variety of criterion measures, including basic personality dimensions, other measures of grandiose and vulnerable narcissism, and indicators of externalizing and internalizing psychopathology. Grandiose and vulnerable composites also behave almost identically across the short- and long-form versions. It is concluded that the FFNI-Short Form (FFNI-SF) offers a well-articulated assessment of the basic traits comprising grandiose and vulnerable narcissism, particularly when assessment time is limited.

The Short Form of the Five-Factor Narcissism Inventory: Psychometric Equivalence of the Turkish Version

“…No significant relationships between the FFNI-SF and BigFive Personality Trait scores were obtained from the TIPI. In the original study (Sherman et al, 2015), low yet significant relationships were found in the undergraduate sample, and moderate-to-high correlations were found in the clinical sample.…”

“…RMSEA values should be between .050 and .080 for acceptable levels of fit, and below .050 for perfect levels of fit to the data (Brown & Cudeck, 1993;Byrne & Campbell, 1999 The models were derived from the original study of Sherman et al (2015). According to the CFA results, the model with 60 items and 15 factor-loadings fit the data best (Model 1).…”

“…Construct validity of the scale was tested through confirmatory factor analysis. Three alternative conceptual models derived from the original study (Sherman et al, 2015) were tested. Model 1 had 60 items loaded on 15 factors: acclaim-seeking, arrogance, authoritativeness, distrust, entitlement, exhibitionism, exploitativeness, grandiose fantasies, indifference, lack of empathy, manipulativeness, need for admiration, reactive anger, shame, and thrill-seeking (denoted as var1-var15 in Figure 1, respectively).…”

“…The scale uses a 5-point Likert-type scale ranging from 1 (strongly disagree) to 5 (strongly agree). Sherman et al (2015) developed the short form of the FFNI, the FFNI-SF. Double-entry intraclass correlations (ICC) indicated high levels of compatibility between the short and original forms.…”

“…Narcissism is an important and complex phenomenon studied in many subfields of psychology that include, but are not limited to, clinical (therapeutic), organizational, developmental, and social psychology (Sherman et al, 2015). Narcissism is characterized by grandiosity, arrogance, and a callous defense of one's self-image as perfect; interest in others is only a means for regulating self-esteem (Kubarych, Deary, & Austin, 2004).…”
