Recently, Moscovitch(2009) suggested concerns about self-attributes as a focus of fear in social anxiety disorder. The purposes of the present study were to examine the unique contributions of concerns about negative self-attributes to the prediction of anxiety responses to a public-speaking situation and to investigate the relative contributions of the dimensions of concerns about negative self-attributes to the prediction of anxiety responses to a public-speaking situation. Furthermore, based on previous studies and the Moscovitch's model of conceptualization, both partial and full mediation models in which speech-related negative automatic thoughts would mediate the relationship between concerns about negative self-attributes and anxiety responses to a public-speaking situation were proposed, and in order to evaluate and compare the two mediation models, structural equation modeling(SEM) approach was used. Seventy nine undergraduate participants completed a questionnaire of concerns about negative self-attributes around 1-2 weeks before the start of experiment, a scale of speech anxiety automatic thoughts just before the speech task, and questions about subjective anxiety, behavioral index of anxiety responses and safety behavior related to public speaking following completion of the speech task. First, concerns about negative self-attributes significantly contributed to the prediction of the initial anxiety during public speaking, behavioral index of anxiety responses, and safety behavior after controlling for the baseline anxiety. Next, of the dimensions of concerns about negative self-attributes examined, concerns about visible sign of anxiety had the strongest effect on all measures of subjective anxiety, as well as safety behavior. Furthermore, SEM revealed that both partial and full mediation models fit the data well, and that the latter was superior to the former. Thus, these results suggest that concerns about negative self attributes, particularly concerns about visible sign of anxiety uniquely contribute to the prediction of anxiety responses to a public-speaking situation and provide the first empirical evidence of the mediating role of speech-related negative automatic thoughts in explaining the relation between concerns about negative self attributes and anxiety responses to a public-speaking situation.
