Development and validation of the positive evaluation core beliefs scale for social anxiety

Fear of positive evaluation (FPE) is becoming recognised as an important component of social anxiety that is distinct from fear of negative evaluation (FNE). While core belief scales exist for fear of negative evaluation (FNE), none has been developed for FPE. Therefore, this paper describes the development and validation of a measure of core beliefs that is specific to FPE. An exploratory factor analysis was performed on 60 initial items with an Australian undergraduate sample, in which a confirmatory factor analysis was performed with an independent Australian general population sample. A series of further analyses were performed to test convergent and divergent validity. The Positive Evaluation Core Beliefs Scale (PECS) emerged as a 17-item two-factor psychometrically valid measure that correlates more strongly with measurement of FPE than FNE. The PECS measure offers a new opportunity for researchers and clinicians to better explore cognitions associated with social anxiety.
