Emotional reactivity (e.g. explosive outbursts, tantrums) is a common but understudied challenge for individuals with autism spectrum disorder. Prior research has relied primarily on questionnaire data or observations of very young children. The current study coded emotional reactivity and recovery during a series of standardized frustration tasks in a sample of psychiatrically hospitalized youth with autism spectrum disorder ( N = 150; mean age: 12.76) inclusive of the full spectrum of intellectual and functional abilities and explored relationships between emotional reactivity and participant characteristics. The amount, intensity, and duration of negative affect and total range of affect significantly increased from a baseline period to frustration tasks and significantly decreased during recovery. Younger children displayed more negative affect overall; however, age did not moderate change in affect from baseline to frustration tasks or recovery. Adaptive functioning and verbal ability both moderated change in affect, with individuals with lower adaptive functioning and minimally verbal individuals displaying greater reactivity and less recovery. Reactivity was unrelated to non-verbal IQ, overall autism symptom severity, and parent-reported psychiatric/behavioral problems. The results highlight the feasibility and importance of examining emotional reactivity in more severely affected individuals and suggest the need to develop more targeted interventions for emotional reactivity in this group. Lay Abstract Large emotional reactions (e.g. outbursts, tantrums) can be common and distressing in the lives of individuals with autism spectrum disorder and their families. Most previous research that has examined these types of emotional responses have used questionnaire data or focused only on young children. In addition, very little research has included individuals across a large range of intellectual and functional abilities or individuals with more severe emotional and/or behavioral difficulties. This study examined emotional reactions to frustrating tasks in 6–21-year-olds with autism spectrum disorder who were psychiatrically hospitalized due to emotional and/or behavioral difficulties. We describe change in the amount, intensity, duration, and range of emotional reactions that the participants displayed from a neutral activity to the frustrating tasks and then to a neutral recovery period. We also examined associations between characteristics of the participants and these emotional reactions. We found that younger children displayed more negative emotions across the neutral and frustrating tasks; however, age did not relate to how big their reactions to frustration were. Furthermore, we found that individuals with fewer adaptive skills (i.e. age-appropriate life skills) and minimally verbal individuals had bigger reactions and recovered less following the frustration tasks. The results highlight the importance of examining emotional reactions in individuals with lower verbal and adaptive abilities and for interventions to consider the connection between verbal and adaptive skills and emotional reactions.
