Intolerance of uncertainty (IU) is a dispositional characteristic reflecting negative cognitive, behavioral, and emotional reactivity in response to events or situations that are uncertain. Although closely associated with a generalized anxiety disorder (GAD) diagnosis in adulthood, IU has received little attention in youth. The goal of this study was to examine the construct in children with GAD and non-anxious children, including its incremental validity in predicting GAD severity and worry beyond anxiety. Ninety-eight children ages 6 to 11 years (51% male; 57% Caucasian) were assessed. The sample included 24 with a GAD diagnosis only (i.e., pure GAD), 36 with GAD plus at least one other disorder (i.e., comorbid GAD), and 38 healthy control children. Clinician, parent, and child reports of IU, anxiety, worry and GAD severity were collected. Significant differences in levels of IU were found across all three groups; the highest levels in children with comorbid GAD, followed by children with pure GAD, and healthy controls. IU significantly contributed to worry but not GAD severity beyond the effects of anxiety. A significantly larger proportion of self-reported IU data was missing for younger (e.g., 6–8 years) as compared to older children, raising question about the validity of the construct in younger children. Overall findings suggest thatIU is not specific to a GAD diagnosis in childhood. IU may instead serve as a broad cognitive risk factor for more severe (e.g., comorbid) forms of affective psychopathology. Future directions for research, including developmental considerations, are discussed.
