Emotion dysregulation in autism: A meta-analysis

Autism is associated with significantly higher rates of internalizing and externalizing disorders compared to neurotypical (NT) individuals. Emotion dysregulation (ED) is prevalent in autistic individuals and has been proposed to underlie both internalizing disorders and behavioral challenges in autism. This study sought to use a meta-analytic approach to examine the magnitude of ED severity in autistic samples compared to NT and other clinical (OC) samples. Following a review of the literature, a total of 35 studies were included in the analyses. In general, when comparing autistic to non-autistic individuals, findings suggest a medium magnitude of difference in ED severity between autistic and comparison groups overall. Subgroup analyses indicate that autistic individuals experience significantly higher ED severity when compared to NT peers. However, when compared to OC peers, the effect is small, suggesting the severity of ED may be more similar between OC and autistic groups. Moderators were also explored, including autistic traits, age, and sex composition. These findings provide integral information about the severity of ED in autistic populations compared to other non-autistic populations, assisting in further clarifying the presence of mental health challenges in autistic youth. Lay Abstract Autistic people often experience other mental health challenges, which makes it particularly important to understand factors that may contribute to the development of these conditions. Emotion dysregulation, or difficulties in effectively regulating one’s own emotions in response to a changing environment, is one factor that is experienced frequently by autistic and non-autistic people and is commonly related to a wide range of mental health conditions. This article represents a quantitative synthesis of the current state of the literature on emotion dysregulation, with a specific focus on how the severity of emotion dysregulation differs across autistic and non-autistic people across the lifespan. The findings suggest elevated emotion dysregulation in autistic individuals compared to both neurotypical and other clinical populations and provide insights into the experiences of emotion dysregulation in autistic people. Overall, this article underscores the importance of more research into emotion dysregulation in autistic people to inform areas of challenges related to emotion dysregulation that can be used to better inform treatment targets.
