Scoring: The Total Anxiety score is based upon 28 items with 9 items comprising the Lie Scale. The Total Anxiety score and the Anxiety subscale scores are determined by the number of "yes" responses to the anxiety items. The Lie Score is determined by "yes" responses to the Lie subscale items and is used to determine if the child was making a valid attempt to respond. The three anxiety subscales should be interpreted cautiously and should be used only as an aid in hypothesis generation due to limited reliability levels. The Total Anxiety Score is expressed as a T score (M=50, sd=10) and the subscales are expressed as scale scores (M=10, sd = 3). Percentile ranks are provided for each of the RCMAS scores. Norms are provided at 1-year intervals and for each ethnic-sex combination for blacks and whites. The Lie Scale is a positive feature of the instrument and is designed to detect acquiescence, social desirability, or faking of responses.
Reliability:
Reliability estimates for internal consistency for
white and black males and females for each of the 12 age levels ranged
from .42
(Age 6, black females) to .87 (Age 12, black males and Age 15, black
males).
Reliability estimates collapsed across the 12 age levels ranged from
.79 to .85
(median=.82). Of the 48 coefficient alphas reported across age, race,
and sex,
17 alphas fall below .80, but in general the Total Anxiety score is
reliable
enough across most ages to permit reliable interpretations. It should
be noted
however, that for black females; at ages 6, 8, 10, and 11, reliability
coefficients are significantly lower than for white females at the same
ages,
and the authors urge that special care be taken when using the RCMAS
with black
females under 12 years of age.
Coefficient alphas are also reported for each of the three anxiety subscales and the Lie Scale. Most of these alphas fall below .80, some far below (.15) indicating poor domain sampling. Individual anxiety subscales are too unreliable to merit interpretation for most persons in the standardization sample. One study reported in the manual found a stability coefficient of .68 for the Total Anxiety score and .58 for the Lie Scale score for 534 children tested 9 months apart. Stability estimates increase dramatically when the interval between testing is shorter. All stability estimates reported in the manual are for children below grade 7. No stability data are reported for junior and senior high school students.
Validity: The manual reports higher
correlations between the RCMAS Total
Anxiety score and a measure of trait anxiety (r=.67) than between Total
Anxiety
and a measure of state anxiety (r=.10) despite the questions about its
measure
of trait anxiety raised by the low test-retest stability coefficients. Other than this, the validity data is sparse
and the factors appear theoretically unrelated. Empirically, the
correlation
between the RCMAS factors range from .49 to .85 (median=.67),
suggesting
correlated factors and an oblique solution. However, the factor
analysis of the
instrument appears to be flawed. The standardization data should be
refactored
before test users can have faith in the dimensions underlying the
RCMAS.
Suggested use: With future work with the scale, particularly the factor analysis undertaken the RCMAS may develop into one of the better measures of anxiety in children and adolescents.
