This study examined the role of anxiety sensitivity as an explanatory variable in the link between two temperamental dimensions (i.e., behavioral inhibition and negative affect) and anxiety disorder symptom severity in a sample of children with anxiety disorders. Forty-four children (52 % African American) between 8 and 12 years of age and their mothers participated in this study. An assessment battery consisting of diagnostic interviews, questionnaires, and behavioral assessment of behavioral inhibition was administered. Findings revealed that anxiety sensitivity was a significant explanatory variable linking child self-reports of behavioral inhibition and negative affect to anxiety disorder symptom severity. For parent-completed measures, only direct effects of behavioral inhibition on anxiety disorder symptom severity were found. The clinical implications of our findings, including the importance and feasibility of anxiety sensitivity and behavioral inhibition assessments as part of routine clinical care of children with anxiety disorders are discussed, along with the limitations of our study.
