Outcome Measures

Primary Outcomes (7)

• Brief version of Fear of Negative Evaluation scale

  The Brief version of Fear of Negative Evaluation scale measures fear of negative evaluation. The scale consists of 12 items, including eight for the straightforwardly worded items and four for the reverse worded items. Each item is rated on a 5-point scale ranging from 1 (not characteristic of me) to 5 (extremely characteristic of me), with higher scores indicating greater fear of negative evaluation. It is recommended that the straightforwardly worded items (8 items) are used for the assessment of fear of negative evaluation. The total score, based on all 12 items, ranges from 12 to 60. When using only the straightforwardly worded items, the total score ranges from 8 to 40.
