Summary

The Multidimensional Anxiety Scale for Children (MASC) is a reliable and valid self-report measure for assessing pediatric anxiety. Its factor structure is stable across demographics, supporting its use in clinical and research settings.

Area of Science:

  • Child and Adolescent Psychology
  • Psychometric Evaluation
  • Mental Health Assessment

Background:

  • Anxiety disorders are prevalent in children and adolescents, necessitating accurate assessment tools.
  • The Multidimensional Anxiety Scale for Children (MASC) was developed to provide a comprehensive measure of pediatric anxiety.
  • Understanding the psychometric properties of the MASC is crucial for its effective application.

Purpose of the Study:

  • To detail the historical development of the MASC.
  • To elucidate the factor structure, reliability, and validity of the MASC.
  • To establish the MASC as a robust tool for pediatric anxiety assessment.

Main Methods:

  • Principal-components factor analysis was employed in two school-based population studies to determine the MASC's factor structure.

  • Test-retest reliability (3 weeks, 3 months), interrater concordance, and convergent/divergent validity were assessed in a clinical population.
  • The MASC comprises 39 items across four main factors: physical symptoms, social anxiety, harm avoidance, and separation anxiety.

    • Main Results:

    • The MASC demonstrated a stable factor structure across age and gender, with excellent internal reliability.
    • Test-retest reliability was satisfactory to excellent over 3 weeks and 3 months.
    • Convergent and divergent validity were supported by correlations with anxiety, depression, and externalizing symptom measures.

    Conclusions:

    • The MASC is a psychometrically sound self-report instrument for evaluating anxiety in children and adolescents.
    • Its established factor structure, reliability, and validity support its use in diverse populations.
    • The MASC shows promise as a valuable tool for both clinical practice and research in pediatric anxiety.
