Objective and perceived arousal during performance of tasks with elements of social threat: the influence of anxiety sensitivity.
This study compared the predictive ability of the original ASI to the ASI-3 and measures of trait and social anxiety in two challenge conditions; hyperventilation or a social challenge. During hyperventilation, the ASI-3 social concerns subscale was a better predictor than the subscales of the original ASI and measures of general trait and social anxiety. During the social manipulation, results indicated the ASI-3 social concerns subscale and the social anxiety measure were significant predictors of anxious response. Results provide evidence that the ASI-3 is an improvement over the original ASI and is a sound overall measure of response to challenge procedures.
