Boredom is a negative emotion that most people experience on occasion. However, some people experience boredom more or are unable to tolerate it, which is called trait boredom. Trait boredom has been well-studied in adolescence and adulthood, but little is known about trait boredom in childhood. The main goal of this study was to measure trait boredom in 4- to 6-year-olds (N = 130) and to test whether it relates to self-regulatory processes in a similar fashion that has been observed in adults and identify strategies children use to cope with boredom. We found boredom in childhood was related to self-regulatory processes in a similar fashion as it does in adults, and most children used social stimulation strategies (e.g., asking to play with a parent) or behavioral strategies (e.g., playing with toys) to cope with boredom. The findings are discussed within the context of prevention and the emotion regulation and boredom literature.
