Multicultural Comparisons
of CBCL/6-18, TRF, and YSR Scores
Applications
of uniform standardized assessment procedures to population samples
of children in different societies make it possible to statistically
compare problems reported in the different societies. L. A. Rescorla
and colleagues from dozens of societies collaborated to compare
CBCL/6-18 scores for 55,508 children in 31 societies, TRF scores
for 30,957 students in 21 societies, and YSR scores for 27,206 youths
in 24 societies. The societies were in Africa, Asia, Australia,
the Caribbean, all parts of Europe, the Middle East, and North America.
The
very large samples and the great diversity of the populations enabled
the researchers to test multicultural variations in problem scores
with more statistical power and precision than in any previous studies.
Statistically significant differences between problem scale scores
from different societies were of small to medium magnitude. Scale
scores for most societies were near the "omnicultural mean"
(the mean of scores from all societies). However, scores from a
few societies were enough lower or enough higher than the omnicultural
mean to warrant different sets of norms. Consequently, data from
societies with relatively low scores and data from societies with
relatively high scores have been used to construct the different
sets of norms that are included in the ADM computer-scoring Module
for Ages 6-18 with Multicultural Options.
Another
important finding was that scores within each society varied much
more than the mean scores varied between societies. In other words,
the differences within societies were greater than the differences
between societies.
The
researchers also identified certain age and gender differences that
were very consistent across societies according to certain informants
but not others. For example, in most societies, parents and teachers
rated boys higher than girls on the Attention Problems syndrome,
but gender differences were negligible in self-ratings of Attention
Problems.
To
determine the degree to which people in different societies rated
the same problems low, medium, and high, the researchers computed
correlations between the mean ratings obtained on each item in each
pair of societies. Averaged across all pairs of societies, the correlations
were .74 for the CBCL and TRF and .69 for the YSR. This indicated
considerable multicultural similarity in the items that were rated
low, medium, and high.
