The Barkley Deficits in Executive Functioning Scale - Children and Adolescents (BDEFS-CA) is an empirically based tool for evaluating clinically significant dimensions of child and adolescent executive functioning. Evidence indicates that the BDEFS-CA is far more predictive of impairments in daily life activities than more time-consuming and costly traditional EF tests. The BDEFS-CA offers an ecologically valid snapshot of the capacities involved in time management, organisation and problem solving, self-restraint, self-motivation, and self-regulation of emotions.

Two parent-report forms are included: a long form (10-15 minutes) and a short form (3-5 minutes).
There is also a short clinical interview form based on the short-form rating scale, for use in unusual circumstances where a parent is unable to complete a rating scale.
Special features include an ADHD risk index in the long form. Complete instructions for scoring and interpreting the scale are provided.

Overview

What does it do?: Provides an ecologically valid assessment of executive functioning deficits in daily life activities.

Age Range: 6-17
Administration Time: Long Form: 10-15 minutes. Short Form: 3-5 minutes.
Format: Parent-report rating scale.
Cost of Additional Forms: No cost: purchasers get permission to reproduce the forms and score sheets for repeated use.

Background

The BDEFS-CA is the culmination of more than 17 years of research and development aimed at identifying the most useful items for the assessment of deficits in executive functioning (EF) in daily life activities. Initially, development of the BDEFS began with forms for use with adults. This manual presents a downward extension of the adult BDEFS, created and normed for use with parents in evaluating their children, ages 6-17 years.

Reliability & Validity

The large normative sample (N=1,922) is representative of the U.S. population in terms of region, socio-economic status, education, ethnicity/race, and gender, based on the 2000 U.S. Census. Unlike other EF rating scales, the normative sample was not drawn from a single state or region, was not filtered to exclude children receiving special education or psychiatric medications, and did not rely on school staff to initially obtain the sample. It is therefore a true general population sample.

Reliability of the scores is quite satisfactory as evidenced by high internal consistency (Cronbach's alpha ranging from .95 to .97 scores across the five scales) and by high test-retest reliability over a 3-5 week interval (ranging from .73 to .82 across scales and .82 for the Total EF Summary Score).

Validity of the scale scores was evident in numerous analyses, including factor analyses; correlation's with other EF rating scales; significant group differences and distinct profile patterns across multiple developmental, learning, psychiatric, and neurological disorders; and correlation's, regression analyses, and group comparisons concerning disorder discrimination and concurrent validity with various measures of functional impairment in major life activities (family functioning, peer relations, educational functioning, community activities, and risk for accidental injuries, among other domains.)

Includes Permission to Photocopy

Enhancing the convenience and value of the BDEFS-CA, 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.
