Introduction: Intolerance of uncertainty (IU), initially studied in the context of internalizing disorders, has recently been shown to be impaired among children with Attention-Deficit/Hyperactivity Disorder (ADHD). Given that ADHD, in addition to internalizing disorders, often co-occurs with emotion regulation deficits, the current study sought to examine the extent to which emotion regulation is associated with IU in a sample of children diagnosed with ADHD.
Method: Twenty-nine children with ADHD (M age = 8.6 ± 1.4 years) participated in the present study. Children completed the Emotion Regulation Index for Children and Adolescents (ERICA) to assess emotion regulation, and the Intolerance of Uncertainty Scale – Short Version (IUS-12) to assess IU. Based on recommendations from previous literature, responses on the IUS-12 were converted to total IU, prospective IU and inhibitory IU, and responses on the ERICA were converted to a total emotion regulation score. Bivariate correlations and hierarchical linear regression analyses were conducted to examine the effects of emotion regulation on IU while controlling for age, sex, and ADHD medications.
Results: Analyses significantly supported the relation between emotion regulation and IU, such that emotion regulation deficits were linked to increases in total IU (β = .39, t = 2.15, p = .04) and inhibitory IU (β = .47, t = 2.64, p = .02), even after controlling for age, sex, and ADHD medications. No associations were observed, however, for the relation between emotion regulation and prospective IU (β = .26, t = 1.41, p = .17).
Conclusion: The current study represents a preliminary analysis on the relation between emotion regulation and IU among children with ADHD. Overall, results suggest that emotion regulation deficits are linked to total IU and inhibitory IU among children with ADHD. Implications, limitations, and future directions are discussed.
