The Behavior Assessment System for Children (BASC)
[23] is a questionnaire assessing psychological functioning
in youth, with different versions for children (ages
8–11), adolescents (ages 12–18), and parents (different
versions for parents of children ages 6–11 and 12–18) to
complete. The BASC scales provide standardized
descriptions of problem behaviors and competencies. All
versions of the BASC generate individual subscales for
Anxiety and Depression. A Somatization subscale also is
generated for both parent-report versions of the BASC,
as well as for the adolescent self-report version. The
BASC has demonstrated criterion-related and construct
validity, has good internal consistency for most of the individual
subscales, and is widely used in both clinical
and research settings [23].
