||The TOF is part of the Achenbach System of Empirically Based Assessment (ASEBA). The TOF is a standardized form for rating observations of behavior, affect, and test-taking style during testing sessions for children aged 2-18. The examiner records observations of a child’s behavior during the test session and scores the child on 125 problem items, using a 4-point scale. The TOF manual provides details of the development of the TOF and its scales, its relations to other instruments, and guidelines for practical applications. The TOF Profile includes empirically based scales and a DSM oriented scale and subscales for each gender at ages 2-5, 6-11, and 12-18.
