The Barkley Deficits in Executive Functioning Scale (BDEFS for Adults) is an empirically based tool for evaluating dimensions of adult executive functioning in daily life. Evidence indicates that the BDEFS is far more predictive of impairments in major life activities than more time-consuming and costly traditional EF tests. The BDEFS offers an ecologically valid snapshot of the capacities involved in time management, organization and problem solving, self-restraint, self-motivation, and self-regulation of emotions. It comprises both self- and other-reports in a long form (15-20 minutes) and a short form (4-5 minutes). Special features include an adult ADHD risk index in the long form. Complete instructions for scoring and interpreting the scale are provided.

“Reliable, empirically based, and convenient to use for clinicians. Allow[s] a doctor to quantify behaviors that can't be readily observed in the clinic.”

ADDitude Magazine


“The BDEFS is a much-needed, clinically relevant tool. This exceptionally well-written manual includes a detailed description of the scale's development, psychometric properties and norms, scoring, and clinical interpretation, as well as the forms themselves. The limited photocopy license clearly enhances the clinical utility of the BDEFS. All professionals responsible for assessing and understanding adults suffering the burden of executive dysfunction will find this scale highly useful and beneficial.”

—Rosemary Tannock, PhD, Department of Human Development and Applied Psychology, Ontario Institute for Studies in Education; Department of Medicine, University of Toronto; and Hospital for Sick Children, Toronto, Canada


“Barkley has created a rating scale that is quick and easy to administer and score. The BDEFS provides valuable information regarding specific executive functioning deficits, including those found in ADHD. This scale does what a good assessment instrument should: not only does it answer questions regarding diagnosis, but it also helps clinicians identify target skills and behaviors for intervention.”

—Peg Dawson, EdD, Center for Learning and Attention Disorders, Seacoast Mental Health Center, Portsmouth, New Hampshire


“The BDEFS ushers in an era of more specific and comprehensive behavioral assessment of executive functioning difficulties encountered by adults during major functional activities. The scales are well designed to be both clinician and patient friendly. The content is broader than other available scales and the normative observations are carefully derived and extensive. Behavioral items are focused around common daily activities rather than clinical symptoms, and thus can be applied in a variety of settings. The combination of self- and other-report forms, as well as long and short forms, provides depth and flexibility. This scale is a powerful complement to traditional executive function tests.”

—Paul J. Eslinger, PhD, Professor of Neurology, Neural and Behavioral Sciences, and Radiology, Penn State Hershey Medical Center and College of Medicine
The BDEFS is based on more than 16 years of research by the developer using a prototype of the BDEFS. The large normative sample (N>1,200) is representative of the U.S. population in terms of region, socioeconomic status, education, ethnicity/race, and gender, based on the 2000 U.S. Census. Scoring sheets present the percentiles for the normative sample by sex and age (18–34, 35–49, 50–64, and 65–81 years old). The normative sample is a true general population sample, not limited to those with an Internet connection and not excluding those with psychiatric disorders, psychiatric medication use, learning disabilities, neurological disorders, or serious medical illnesses.

Reliability
Reliability of the scores is quite satisfactory as evidenced by high internal consistency (Cronbach's alpha ranging from .91 to .95 scores across the five scales); good interobserver agreement (.66 to .79 across scales); and high test–retest reliability over a 2–3 week interval (ranging from .62 to .90 across scales and .84 for the Total EF Summary Score).

Validity
Validity of the scale scores was evident in numerous analyses, including factor analyses; correlations with other measures of EF; and correlations, regression analyses, and group comparisons concerning disorder discrimination and concurrent validity with various measures of functional impairment in major life activities (associated risks for ADHD, educational history, occupational functioning, social relationships, marriage, driving, financial management, crime and drug use, parenting stress, and offspring psychopathology, among other domains).
