This study aimed to test the construct validity of three different forms of the Fear of Negative Evaluation Scale. The Brief Fear of Negative Evaluation Scale (BFNE), the Brief Fear of Negative Evaluation Scale-Revised (BFNE-II) and the Brief Fear of Negative Evaluation Scale-Straightforward (BFNE-S) were applied to a group of 652 people in total, including 339 females, 313 males, 320 university students, and 332 high school students. To examine the factor structure of the scales, confirmatory factor analysis was performed. Item analysis were conducted to compare the psychometric properties of straightforwardly scored and reverse-scored items. To investigate the internal consistency coefficients of the scales, Cronbach's alpha coefficients were calculated. As a result of the confirmatory factor analysis performed for three different forms of the scale, it was found that the BFNE did not fit well to a two-factor model, while the BFNE-II and BFNE-S fit well to a single-factor model. The item analyses conducted for three different forms, and the calculated internal consistency coefficients also revealed that the BFNE-II and BFNE-S had better psychometric properties than the BFNE. These findings are in parallel with the findings obtained in studies conducted on the construct validity of the original English version of the BFNE in the last 15 years. Based on these findings, it was concluded that BFNE-S is the appropriate tool to measure the fear of negative evaluation of high school and university students in Turkey due to its theoretically based, robust factor structure and its high internal consistency coefficient despite consisting of fewer items.
