Although disgust sensitivity (DS) has been implicated in the development of anxiety disorders in children, the absence of a measure of DS specifically for children has not allowed for an adequate test of this claim. To fill this important gap in the literature, this investigation presents a series of studies on the development and examination of the psychometric properties (including reliability, validity, and factor structure) of scores on a newly developed Child Disgust Scale (CDS). Exploratory factor analysis in Study 1 (N = 1,500) found that a bifactor model, which allows for a "g" DS factor in addition to 2 distinct factors of Disgust Avoidance and Disgust Affect, was the best fit for the data. Study 2 (N = 573) confirmed a two-factor bifactor model above and beyond a 1-factor model that controlled for method effects due to reverse-worded items. Results from Study 3 (N = 50) provided support for convergent and discriminant validity such that scores on the CDS were significantly correlated with measures of anxiety and fear, but not depression. Finally, Study 4 (N = 86) found that the CDS differentiated children with a diagnosis of specific phobia (n = 43) from a matched nonclinical community sample of children (n = 43), such that those with a specific phobia reported greater DS compared with controls. Results from these studies suggest that the CDS is a developmentally appropriate measure with good psychometric properties that can aid research on the role of disgust sensitivity in anxiety-related disorders in children.
