Externalizing Behavior - Behavior Assessment System for
Children-Second Edition (BASC-2)
Externalizing Behavior (EB) was measured via parent report using the
Externalizing Problems composite on the Behavior Assessment System for
Children (BASC-2, Reynolds & Kamphaus, 2004). The preschool form used
with 2- to 5-year-olds (PRS-P) yields an externalizing composite
comprised of the Hyperactivity and Aggression subscales. The child form
used with 6- to 11-year-olds (PRS-C) yields an externalizing comprised
of the Hyperactivity, Aggression, and Conduct subscales.
