Emotion regulation and executive function: Associations with depression and anxiety in autism

Adolescents and young adults with autism spectrum disorder (ASD) are prone to experience co-occurring mental health conditions such as mood or anxiety disorders, as well as impairments in emotion regulation and executive functioning. However, little research has examined inter-relationships among these constructs, despite evidence of additional stressors and increased risk of internalizing disorders at this age, relative to non-autistic individuals. If either emotion regulation or executive functioning are shown to have patterns of association with mental health, this can inform mechanism-based intervention. Fifty-seven autistic adolescents and adults (16–25 years) with ASD in a transition intervention completed questionnaires and clinician-administered measures at baseline. Analyses assessed whether executive functioning impairment, above and beyond emotion regulation impairment, were associated with depression and anxiety symptoms. ASD characteristics, emotion regulation, anxiety, and depression were significantly correlated. ASD characteristics was a significant contributor to depression and emotion regulation impairments were significant contributors to anxiety and depression. Findings indicated that inhibition difficulties did not uniquely contribute to depression or anxiety above emotion regulation impairment. Difficulties in cognitive flexibility were associated with depression above and beyond ASD characteristics, IQ, and emotion regulation, but not associated with anxiety. Although preliminary, findings suggest that inflexibility and regulatory impairment should be considered in depression remediation approaches. Improving ER, on the other hand, may have broader transdiagnostic impact across both mood and anxiety symptoms in ASD.
