'Uncertainty attunement' has explanatory value in understanding autistic anxiety

The role of emotion dysregulation and intolerance of uncertainty in autism: Transdiagnostic factors influencing co-occurring conditions

BACKGROUND

Individuals with autism spectrum disorders (ASD) are more likely to have co-occurring psychiatric conditions such as depression and anxiety. Transdiagnostic constructs such as intolerance of uncertainty (IU) and emotion dysregulation (ED) have both been shown to be individually associated with depression and anxiety in those with ASD.

AIMS

The current study examined the relationship between IU and ED, depression, and anxiety in an ED treatment-seeking sample and examined whether ED acts as a mediator between IU-depression and IU-anxiety.

METHODS AND PROCEDURES

We examined baseline scores for 78 adolescents and young adults (12-21 years old) who were participating in an ED treatment. We assessed for correlations between IU, Reactivity and Dysphoria, anxiety, and depression symptoms, and then conducted mediation analyses to determine whether Reactivity and Dysphoria functioned as a mediator in IU- anxiety and IU- depression relationships.

OUTCOMES AND RESULTS

Concordant with prior research, ED, IU, anxiety, and depression scores were correlated. Both Reactivity and Dysphoria were found to mediate both IU-depression and IU-anxiety.

CONCLUSIONS AND IMPLICATIONS

Findings suggest that ED contributes to how IU affects psychopathology. Furthermore, both IU and ED may be pertinent treatment targets for individuals with depression or anxiety and ASD.
