Barkley Deficits in Executive Functioning Scale (BDEFS)

by Russell A. Barkley

Full Description:   

The Barkley Deficits in Executive Functioning Scale (BDEFS) 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. Provided are 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.

Includes Permission to Photocopy Enhancing the convenience and value of the BDEFS, the limited photocopy license allows purchasers to reproduce the forms and score sheets and yields considerable cost savings over other available scales. The large format and sturdy wire binding facilitate photocopying.

Age Range: 18-81

    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). Unlike other EF rating scales, 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 (Chronbach'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).
