Children’s Manifest Anxiety Scale (CMAS)

The Children’s Manifest Anxiety Scale, or CMAS, was developed to evaluate the nature and the degree of anxiety in children and adolescents. Subscales for the instrument include: Physiological Anxiety, worry-oversensitivity, social concerns, total anxiety, and lies. The current edition of the instrument is the revised edition RCMAS. The revised edition allows for the instrument to be an objective measure used by group administration, to cover more areas of anxiety, to treat between uni-dimensional or multidimensional, to be more diverse, to take minimal time to administer (10 to 15 minutes) and to be valid.

The test is a self-report specifically made for use by children and adolescents from 6-9 years. The test consists of 37 items with only yes and no options to answer. Total anxiety is comprised of the first 28 items and the Lie Scale is the last 9 items.

Reliability and Validity

Reliability for the scale is not consistent, varying between ages and subscales. For black kids under 6 years, alpha coefficients were .41-.39. The Lie Scale has a reported alpha rating of .77 with older children (Reynolds & Richmond, 1994). Test should be used cautiously when participant is under the age of six. Test-retest correlation for the Total Anxiety scale is reported at .68 and .58 for the Lie Scale (Reynolds, 1981). Reynolds reported significant correlation with the State-Trait Anxiety Inventory for Children, .78 (Trait scale) and .08 (State scale). Also, there is a high correlation rating with the Walker Problem Behavior Identification Checklist.
