This study reports on recent trends in the psychological research literature on the use of measures in the assessment of anxiety. An analysis of PsycINFO, from 2000-2005, showed that the Beck Anxiety Inventory and the Anxiety Sensitivity Index had the highest hit rates. The results indicate that many anxiety instruments that are popular in clinical settings have a sparse research base. These findings point to a need for instructors to address the importance of the level of research credibility of mental health assessment instruments in their teaching. (Contains 1 table.)
