Objective: The objectives of this study were to evaluate whether behaviors that differentiate children and adolescents with ADHD from those without are related to the primary diagnostic criteria (i.e., inattention and impulsivity--hyperactivity), symptoms of comorbid conditions, functional impairment, or a combination, and to determine whether…

A sample of 79 individuals participated in the present study to evaluate the test score stability (8-week test-retest interval) and construct validity of the scores of the Adult Manifest Anxiety Scale-College Version, a new measure used to assess anxiety in college students, for application to graduate-level students. Results of the study…

In this study, the authors investigated the temporal stability and construct validity of the Adult Manifest Anxiety Scale-College Version (AMAS-C; C. R. Reynolds, B. O. Richmond, & P. A. Lowe, 2003b) scores. Results indicated that the AMAS-C scores had adequate to excellent test score stability, and evidence supported the construct validity of the…

The study evaluated the emotional stability of 465 children (grades 2 through 12) in special education programs for the gifted compared to that of 329 children attending regular classroom programs. Two anxiety scales were used in the study: the Revised Children's Manifest Anxiety Scale and the Trait Scale of the State-Trait Anxiety Inventory for…

Responses of 584 high IQ children to the Revised Children's Manifest Anxiety Scale were submitted to a factor analysis. The five factors that emerged were highly similar to factors found with the normative sample. Reliability estimates for each age group on three subscales of anxiety and for the total scale support its clinical and research use.…

On multiple measures of chronic, manifest anxiety, the intellectually gifted sample (N=465) consistently displayed lower levels of anxiety than their nongifted peers (N=329), indicating better overall adjustment. (Author)

In support of the construct validity of the revised scale, a high correlation was observed between the revised Children's Manifest Anxiety Scale (CMAS) and the trait anxiety inventory, whereas there was no significant correlation with the state anxiety inventory. (Author)

Performed exploratory factor analysis of the responses of 458 older adults, aged 60 to 100 years, to the Adult Manifest Anxiety Scale-Elderly Version (based on a scale by J. Taylor, 1953). Found a three-factor structure of anxiety consistent with current theories of anxiety that supports the construct validity of the measure. (SLD)

The psychometric properties of the Adult Manifest Anxiety Scale-Elderly Version (AMAS-E) scores were evaluated in two studies. In Study 1, the temporal stability and construct validity of the AMAS-E test scores were examined in a group of 226 older adults, aged 60 years and older. Results indicated adequate to excellent temporal stability (2-week…

The Revised Children's Manifest Anxiety Scale was administered to 534 children (grades 4-6) at the beginning and end of the school year. The total anxiety score correlated .68 across the nine-month period, supporting the temporal stability of the test. (Author/BW)

Responses of 871 adults to the Adult Manifest Anxiety Scale-Adult version (AMAS-A) were factor analyzed using the method of principal axis factoring with promax rotation. Factor analysis yielded a four-factor solution: three anxiety factors (Worry/Oversensitivity, Stress, and Physiological Anxiety) and a Lie factor. The AMAS-A's three-factor…

To develop normative data for the revision of the Children's Manifest Anxiety Scale, the scale was administered to 4,972 children, ages 6 to 19 years, representing all geographic regions of the United States. Reliability was satisfactory for all groups except Black females below age 12 years. (Author/BW)

The factor structure of scores on the Adult Manifest Anxiety Scale-College Version (AMAS-C), a new self-report measure of chronic, manifest anxiety, is examined across gender for a sample of 943 college students (608 women and 335 men). Values for the coefficient of congruence and salient variable similarity index are calculated between each of…

The factor structure, and thereby the underlying construct of the What I Think and Feel Test (WITF) was determined. The delineation of subscales of anxiety within this revision of the Children's Manifest Anxiety Scale was significant, since anxiety is a multidimensional characteristic. Responses of 329 children (grades 1-12) to the 28 anxiety…

A modified multitrait-multimethod validation matrix was generated to evaluate the construct validity of the Revised Children's Manifest Anxiety Scale (RCMAS). Results were consistent with the use of RCMAS as a measure of chronic, manifest anxiety levels in children. Large correlations occurred with other trait measures of anxiety. (Author/PN)
