Public speaking is the most commonly reported fearful social situation. Although a number of contemporary theories emphasize the importance of cognitive processes in social anxiety, there is no instrument available to assess fearful thoughts experienced during public speaking. The Self-Statements During Public Speaking (SSPS) scale is a 10-item questionnaire consisting of two 5-item subscales, the Positive Self-Statements (SSPS-P) and the Negative Self-Statements subscale (SSPS-N). Four studies report on the development and the preliminary psychometric properties of this instrument.
