Multidimensional Anxiety Scale for Children

The Multidimensional Anxiety Scale for Children (MASC-2) is a 39-item self-report measure of anxiety symptoms in children and adolescents ages 8–19 years. Developed by John March and colleagues in 1997, the MASC operationalizes anxiety as a multifaceted construct comprising physical symptoms, social anxiety, harm avoidance, and separation/panic concerns. The revised MASC-2 (2012) improved psychometric properties and clinical utility. It is widely used in clinical and research settings for screening, diagnosis, and outcome measurement in childhood anxiety disorders.
