AB  - Intolerance of uncertainty (IU), a dispositional negative orientation toward 
      uncertainty and its consequences, has been studied in adults, but research has 
      only recently examined IU in youth. Despite some advances, little is known about 
      the factor structure of measures of IU in youth. The present study used 
      confirmatory factor analysis to examine the structure of IU as measured by the 
      Intolerance of Uncertainty Scale for Children (IUSC; Comer et al., 2009) in a 
      sample of youth (N=368) 9-18 years of age (M(age)=12.47) with and without anxiety 
      disorders and their mothers. Findings demonstrated multiple acceptable factor 
      structures: a correlated factors 2-factor structure and a bifactor model where a 
      general factor underlies all items. While the bifactor model provides better fit 
      and reliability to the data, multivariate analyses indicated that the 2-factor 
      structure distinguishes apprehensive anxiety regarding future events (prospective 
      IU) from present-focused inhibition of behavior due to uncertainty and negative 
      reactions to the presence of uncertainty (inhibitory IU); a total IU score 
      predicted all anxiety domains for self- and parent-reports except for 
      parent-report harm avoidance. Findings are discussed in terms of consistency of 
      IU across adult and youth samples, and how results can inform treatment efforts 
      and etiologic models of IU and anxiety.
