Teacher's Report Form

The full measure of 113 items of Teacher Report Form of Child Behavior Checklist (Achenbach, 1991) were administered prior to Grade 6. Only 34 items describing externalizing behavior problems were administered in Grade 6. This 34-item version consists of the Delinquency, Aggression and Externalizing scale item responses.


The Teacher's Report Form (Achenbach System of Empirically Based Assessment 1991), evaluates behavior problems that a child may display in school. The full version includes Adaptive Functioning and Academic Performance sections, but these were not included in this version of the measure. Only the Problem Section was used in the Fast Track Project. The Child Behavior Checklist (Achenbach 1991) is a parent measure that also evaluates behavior problems a child may display and was collected at the same time as the TRF and measures the same constructs. Both are considered to be extremely reliable measures of behavior problems.

Each item on the Problem Section of the TRF contains a statement about a child's behavior. The teacher selects the response that assesses how well each statement describes the child, either currently or within the previous two months. Response choices include: "Not True" (0), "Somewhat or Sometimes True" (1), and "Very True or Often True" (2).

Analysts should note that a number of scores were positively distributed for both the normative and the high-risk samples. For year 1, analysis of scores on four raw scores, three T scores, and five Fast Track narrow band scales showed a floor effect. In addition, it needs to be noted that a number of items in the scores had a zero variation. Scores affected by the zero variation for some items included the Delinquency Raw Score (high-risk boys), the Somatic Complaints Raw Score (high-risk and normative girls), the Thought Problems Raw Score (normative boys and girls), and the Total Problems Raw Score (high-risk boys and girls and normative boys and girls).

Caution should be used in analyzing the raw score versions of the Achenbach scales with males and females, as the scores are based on different items. This does not apply to the T-scores (which are normed separately by gender) or the Fast Track narrow band scales (which use the same items for each gender).

Finally, analysts should note that two scores, the Somatic Complaints Raw Score and the Somatic Complaints T Score, both showed differences between the control and intervention groups in the combined sample and in the boys only sample.
