Re-assessing the assessment of fears of positive and negative evaluation: Scale development and psychometric evaluation of the Bivalent Fear of Evaluation Scale (BFOES)

The bivalent fear of evaluation (BFOE) model of social anxiety divides fear of evaluation into two distinct valences: fear of positive evaluation (FPE) and fear of negative evaluation (FNE). However, there is evidence that the two most widely utilized and psychometrically supported measures of FNE and FPE contain items which are ambiguous with regard to valence of evaluative fear. To formally address this, the BFOE Scale (BFOES) was developed, by merging items from measures of FNE and FPE into a single scale with an integrated response format. The present studies examined the psychometric profile of the BFOES across a large pooled archival dataset ( N = 2216), which included approximately 10 % ( n = 224) patients with social anxiety disorder (SAD). The factorial validity, internal consistency, and construct validity of the BFOES were examined. Additionally, item response theory analyses were employed for the purpose of merging items from self -report scales which utilized different Likert-type response formats. Results from both studies provided support for the psychometric profile of the BFOES. The implications of the BFOES for the assessment of social anxiety, and theoretical models of fear of evaluation and SAD, are discussed.
