Individuals with high autistic traits have difficulty in regulating their negative emotions. However, few studies clarify the relationship between autistic traits and cognitive emotion regulation strategies. This study examined the association between adaptive and maladaptive strategies in cognitive emotion regulation and autistic traits using a non-clinical sample. Two hundred and thirty-four participants completed the Japanese version of the Social Responsiveness Scale-2 (Adult Self-Report version) and the Japanese version of the Cognitive Emotion Regulation Questionnaire. The results showed that autistic traits were negatively associated with the use of adaptive subordinate strategies for cognitive emotion regulation. By contrast, autistic traits were positively associated with the use of maladaptive subordinate strategies of cognitive emotion regulation. The cognitive and emotional characteristics of autism spectrum disorder, such as perspective taking and executive function, contextualize these results. These findings can help guide not only our understanding of the relationship between autistic traits and cognitive emotion regulation but also develop interventions aimed at facilitating the use of adaptive cognitive emotion regulation strategies and preventing the use of maladapted strategies in individuals with high autistic traits.
