    1. Psychometrics for a Shortened Behavior Rating Inventory of Executive Functioning D. Beebe, K. Byars, A. Nichols, L. Groesz, C. Wells The Behavior Rating Inventory of Executive Functioning (BRIEF) is the first empirically supported questionnaire designed to assess children’s functional use of executive skills in daily life. In our clinical practice, we saw the need for an abbreviated alternative to the 86-item parent BRIEF to act as a screening tool. With the consent of the BRIEF’s authors and publishers, we developed a 24-item parent-report short form (BRIEF-S). Three items from each BRIEF subscale were selected because of their high item-subscale correlations and their lack of redundancy with items from another behavior screener (the BASC Monitor). The BRIEF-S was administered to parents of children aged 5-16 who were referred for suspected ADHD (n=84) or for suspected sleep-disordered breathing (n=32). Despite the shortened format, internal consistency remained good (median alpha=.79). Maternal and paternal reports were moderately correlated. The factor structure of the BRIEF-S mirrored that of the full BRIEF. Construct validity was supported by correlating the BRIEF-S with the corresponding scales from the full BRIEF (median rho=.88), with the BRIEF scales omitting items from the BRIEF-S (median rho=.77), and with the hyperactivity and inattention subscales from the BASC Monitor. Children referred for suspected ADHD displayed poor BRIEF-S scores compared to norms, supporting criterion validity. There was evidence of a low “ceiling” on one subscale, but this was not a substantial issue on composite indexes of behavior regulation, metacognition, and overall executive functioning. Thus, there is preliminary psychometric support for the BRIEF-S as a screening tool, though ceiling effects can complicate subscale interpretation.
