Teacher Report Form – Externalizing Items Only

Teacher Report Form (externalizing items only), (Achenbach, 1991), includes 34 items describing externalizing behavior problems. The version used with this update only consists of the Delinquency, Aggression and Externalizing scale item responses.

Abstract: The Teacher Report Form (TRF; Grade 6) includes 34 items describing externalizing behavior problems. The original version of the TRF consisted of 113 items, and included scales describing Internalizing, Externalizing, Delinquency and Aggression, Attention Problems, Withdrawal, Anxiety/Depression, Somatic Complaints, Social Problems, Thought Problems and Sex Problems. The full measure of 113 items was administered prior to Grade 6. The version used with this update only consists of the Delinquency, Aggression and Externalizing scale item responses. For these 34 items, teachers responded to each item using a 3-point Likert scale (0 - Not True (as far as you know), 1 - Somewhat or Sometimes True, 2 - Very True or Often True). The original scoring method was established by Achenbach and Edelbrock (1991), which included a raw total score and T-score for the dimensions of Delinquent, Aggressive and Externalizing child behavior problems. For the purposes of this study, averages of item responses for each dimension were calculated if 50% or more of the item responses were present, then the average was multiplied by the number of items for that scale to obtain a total score that would allow determination of the corresponding T-score according to Achenbach's 1991 profiles. The percentage of responses without missing data was 92.6%; an additional 3% of the respondents had 50% or more item responses available allowing for the calculation of an average scale score on greater than 17, but less than 34 items. The TRF allows for the teacher's judgment of a student to be obtained in a standardized fashion. It provides for the assessment of conduct disorders. T-scores enable the comparison of the researcher's study group with a normative sample of peers.
