Development of the Anger Children's Cognitive Error Scale and the Anger Children's Automatic Thought Scale

Empirical studies between anger and anger-provoking cognitive variables in children and adolescents are lacking, despite numerous studies on internalising and externalising problems.

The purpose of this study was to develop new questionnaires for anger-provoking cognitive errors and automatic thoughts, and examine relationships between anger, cognitive errors, and automatic thoughts in children and adolescents.

Participants were 485 Japanese children and adolescents aged 9-15 years old (254 females; average age 12.07; SD = 1.81). They completed the Anger Children's Cognitive Error Scale (A-CCES) and the Anger Children's Automatic Thought Scale (A-CATS), which were developed in this study, as well as the Anger Scale for Children and Adolescents and the Japanese version of Short Spence Children's Anxiety Scale.

Both the A-CCES and the A-CATS had adequate reliability (internal consistency) and validity (face validity, structural validity and construct validity). A hierarchal regression analysis indicated that automatic thoughts were positively and moderately related to anger (β = .37) after controlling for age, gender, anxiety symptoms, cognitive errors and interaction term. Moreover, a mediation analysis indicated that automatic thoughts significantly mediated the relationship between cognitive errors and anger (indirect effect, 0.24; 95% CI: .020 to .036).

This study developed the new questionnaires to assess anger-provoking cognitive errors and automatic thoughts. In addition, this study revealed that automatic thoughts rather than cognitive errors are associated with anger in children and adolescents.
