measure of the presence and
intensity of psychological
traits or symptom clusters
that are clinically relevant
in the broad assessment of
individuals with eating disorders.

Scoring Program
The EDI-3 is a revision of
one of the most widely used
self-report measures of psychological
traits or constructs shown
to be clinically relevant
in individuals with eating
disorders--the EDI-2. This
new version is a standardized
and easily administered measure
yielding objective scores
and profiles that are useful
in case conceptualization
and treatment planning for
individuals with a confirmed
or suspected eating disorder.
It also is a valuable research
tool for assessing areas of
psychopathology, identifying
meaningful patient subgroups,
and assessing treatment outcome.
It can be completed in a relatively
brief period of time and may
be administered either individually
or in a group setting.
The EDI-3 has been significantly
enhanced to provide scales
and composites for measuring
constructs that are more consistent
with the psychological domains
identified as relevant to
eating disorders by modern
theories. The item set from
the original EDI, as well
as items from the 1991 revision
(EDI-2), have been carefully
preserved so that clinicians
and researchers can continue
to compare data collected
previously with data from
the revised EDI-3.
The EDI-3 consists of 91 items
organized onto 12 primary
scales, consisting of 3 eating-disorder-specific
scales and 9 general psychological
scales that are highly relevant
to, but not specific to, eating
disorders. It also yields
six composites: one that is
eating-disorder specific (i.e.,
Eating Disorder Risk) and
five that are general integrative
psychological constructs (i.e.,
Ineffectiveness, Interpersonal
Problems, Affective Problems,
Overcontrol, General Psychological
Maladjustment).
Special
Features of the EDI-3
• Easily administered
and scored, the EDI-3 yields
12 nonoverlapping scale scores
and 6 composite scores that
can be used to create clinically
meaningful profiles that can
be linked to treatment plans,
specific interventions, and
treatment monitoring.
• The EDI-3 now has
clinical norms for adolescents
in addition to U.S. adult
and international adult clinical
norms. It also provides multisite
nonclinical comparison samples.
• The EDI-3 Referral
Form Kit (EDI-3 RF) can be
administered in clinical settings
as well as high schools, colleges,
athletic programs, or other
nonclinical settings to assist
in determining if an individual
should be referred for a professional
evaluation. The EDI-3 Referral
Form Manual included in the
kit provides information on
the administration, interpretation,
and scoring of the EDI-3 RF.
• The expanded EDI-3
Professional Manual includes
extensive clinical interpretive
guidelines with detailed case
examples.
• The easy-to-use T-Score
and Percentile Profile Forms
include critical item sets
that allow for the development
of a more meaningful clinical
picture.
• The EDI-3 Symptom
Checklist (EDI-3 SC) assists
with the systematic gathering
of symptom data that can aid
in determining if the DSM-IV-TR™
diagnostic criteria are met.
• The EDI-3 demonstrates
excellent reliability and
validity.
• The EDI-3 uses a 0-4
point scoring system that
improves the reliabilities
of some scales and yields
a wider range of scores.
• A new computer-based
scoring program, the EDI™-3
SP, generates a detailed clinical
profile and scoring report
for each client.
TABLE 1: Differences in the EDI-2 and the EDI-3
1 These scales were not on the original EDI.
2 Composite scales and Response Style Indicators are completely new to the EDI-3.
Note: Item 71 from the EDI-2 is included on the EDI-3 item sheet, but is not scored on the EDI-3.
Normative
Groups
The EDI-3 provides normative
information for females with
eating disorders who are ages
13-53 years. All normative
protocols were collected in
various outpatient and inpatient
settings. Normative information
is provided for the following
DSM-IV-TR™ diagnostic
groups: (a) Anorexia Nervosa-Restricting
type; (b) Anorexia Nervosa-Binge-Eating/Purging
type; (c) Bulimia Nervosa;
and (d) Eating Disorders Not
Otherwise Specified.
Reliability
and Validity
The Eating Disorder Risk Composite
reliability ranges from .90-.97
(median = .94) across the
four diagnostic groups and
the three normative groups.
For the three Eating Disorder
Risk scales, all reliabilities
are generally in the high
.80s to low .90s across the
normative groups. Additionally,
the reliabilities for the
Psychological scales and composites
are high; the overall General
Psychological Maladjustment
Composite range from .93-.97
across the three normative
groups. With one exception,
all of the other composite
reliabilities are in the .80s-.90s
for the normative samples.
Overall, the test-retest stability
coefficients are excellent.
The Eating Disorder Risk Composite
coefficient is .98 and the
General Psychological Maladjustment
Composite coefficient is .97.
The median test-retest coefficients
for the Eating Disorder Risk
scales and the Psychological
scales are .95 and .93, respectively.
For the Eating Disorder Risk
scales, the Drive for Thinness
and Body Dissatisfaction scales
are highly correlated (.96
and .97, respectively) with
their EDI-2 counterparts for
both the U.S. adult and adolescent
clinical samples. The Professional
Manual shows the relationships
with a broad range of external
instruments, and presents
factor-analytic data that
provides the internal structure
of the EDI-3.
EDI-3
Symptom Checklist (EDI-3 SC)
The EDI-3 SC is an independent
and structured self-report
form. This form is easy to
complete and provides data
regarding frequency of symptoms
(i.e., binge eating; self-induced
vomiting; exercise patterns;
use of laxatives, diet pills,
and diuretics). Detailed information
regarding the symptom areas
assessed by the EDI-3 SC is
necessary for determining
whether patients meet the
formal diagnostic criteria
for an eating disorder.
EDI-3
Referral Form Kit (EDI-3 RF)
The EDI-3 Referral Form Kit
(EDI-3 RF) is specifically
designed to help identify
individuals who are at risk
for eating disorders. The
kit consists of the EDI-3
Referral Form Manual and a
package of 25 EDI-3 Referral
Forms.

An abbreviated
form of the EDI-3, the EDI-3
RF includes the three scales
that compose the Eating Disorder
Risk Composite: Drive for
Thinness, Bulimia, and Body
Dissatisfaction. In addition
to the 25 EDI-3 questions,
this brief self-report form
includes behavioral symptom
questions to identify individuals
with potential eating disorders
or pathology. Referral indexes
are used to identify individuals
who have or are at risk for
eating disorders. These indexes
are based on the individual's
body mass index (BMI) only,
on BMI plus EDI-3 questions
about excessive eating concerns,
and on the responses given
to behavioral questions pertaining
to eating-disorder pathology.

The EDI-3 SP is the unlimited-use
computer-based scoring program
for the new Eating Disorder
Inventory™-3 (EDI™-3).
After administration of the
EDI-3, demographic information
and item responses are hand-entered
into the software program
by the clinician; the software
generates a detailed, individualized
Score Report with raw scores
for all EDI-3 scales for each
client. Reports can be edited
on-screen to incorporate additional
clinical information or to
edit descriptive statements.
Features
• Eating Disorder Inventory™-2
(EDI™-2) scores can be
imported into the software.
The EDI-3 SP also produces
a table in the Score Report
that includes the EDI-2 equivalent
raw scores.
• Raw scores, T scores,
percentiles, and qualitative
classifications are generated
for each of the EDI-3 scales
and composites.
• T-score and percentile
profiles graphically display
the client's scores compared
to both the Typical Clinical
range and the female control
group.
• Information on weight,
BMI, and weight history also
appears on the Score Report.
Requirements
Windows® 95/NT 4.0 with
Internet Explorer 4.0 or higher,
Windows® 98/Me/2000/XP;
CD-ROM drive for installation;
Internet connection or telephone
for software activation.
