of AS will help enhance an understanding of the determinants of common and fundamental fears.
Although there have been only a handful of studies of the expectancy theory, available findings cast doubt on the adequacy of the theory. Indeed, some studies have obtained results that are directly opposite to those predicted by Equation 1. Modifications to this equation may be necessary. We have proposed one modification, which was designed to account for recent findings (e.g., Telch & Harrington, 1994). However, it remains to be seen whether our modified equation outperforms Equation 1 when new data sets are used. Also, to determine whether AS is a critical variable, the predictive power of these equations should be directly compared to those of other models, including models that do not include AS as a variable. Such empirically based comparisons should advance our understanding of the role of AS in anxiety disorders and subsequently direct effective treatment strategies.
