Introduction
‘The NEO-4 is a four-factor version of the Revised NEO
Personality Inventory (NEO PI-R) intended for use in sit
ations where waits in the domains of Ext
‘Openness to Experience (0), Agrecableness (A), and Cot
scientiousness (C) are the chief focus of interest. These
might include the areas of career counseling, career devel-
‘opment, employee training, and personal growth,
‘The questionnaire items, scoring keys, and scale norms
in the NEO-4 are identical to those found in the NEO P-R,
for the four factors of E, O, A, and C, and users are encour
aged to consult the Professional Manual for the NEO PI-R
(Costa & McCrae, 19922) and associated publications for
detailed information on their rationale, development, relia-
bility, factor structure, and validity. However, the NEO-4
‘omits all items in the domain of Neuroticism (N), which
relates to individual differences in such traits as Anxiety,
Depression, and Vulnerability. The resulting instrument is
somewhat shorter and may be considered more appropriate
for certain uses. For example, individuals may be more
willing to discuss their personality profiles in a workshop
‘or group setting if information on emotional stability is not
included. Studies of vocational interests show that
Neuroticism is largely unrelated to interests, so N scores
{would contribute little to this area of vocational counseling
(Costa, McCrae, & Holland, 1984).
Each of the four domains in the NEO-4 is relevant to
‘understanding many aspects of personality. The domains
can be interpreted at the global factor level or, for a more
detailed analysis, at the level of 24 facet scales (¢.g.,
‘Warmth, Openness to Ideas, Altruism, Order, ete.)
In addition, this manual supplement presents a new way
to interpret the four domains in terms of six personal
styles: Interests, Interactions, Activity, Attitudes, Learning,
and Character. Each style is defined by a circumplex com-
bining information from two of the four factors—for
example, E and A form the basis of Wiggins's (1979) well-
known Interpersonal Circumplex; here, they form the ba
of the Style of Interaction. Interpretation of styles supple-
ments interpretations of domains and facets.
This manual supplement and a feedback sheet, Your
NEO-4 Summary, are also appropriate for users of the full
NEO PLR or the NEO-FFI who wish to interpret results in
terms of personality styles.
‘Some professionals will notice that the four domains
assessed by the NEO-4 correspond to the four preferences
measured by the Myers-Brigas ‘Type Indicator (MBTH
Myers & McCauley, 1985)—an instrument that is widely
used in organizational psychology and career develop-
iment. Although clearly related, there are substantial dilfer-
fenees between the NEO-4 and the MBTI in both
psychometric properties and conceptual interpretation. AS
ftiscussed in more detail in the Research Update section,
the NEO-4 (a) regards traits as cont
instead of dichotomous preferences, (b) assesses Six sPe~
in each domain, and (c) characterizes peo-
ple in terms of six different styles instead of single
psychological type. These differences are based on a body
ical research conducted over the last 30 years.

‘Test Materials and Use
In addition to the NEO PE-R manual and this manual
supplement, the NEO-4 materials consist of a reusable
item booklet for self-reports (Form S), a reusable item
booklet for ratings by another individual (Form R), a hand
scorable answer sheet, a profile form, a style graphs book:
Jet, Your NEO-4 Summary, and overhead transparencies of
the six style graphs. The item booklets include the 192
items and instructions for using the answer sheet, ‘The
answer shect is a two-part, carbonless form which includes
a scoring template and can be used with either item book-
let. It contains areas for recording identifying and demo-
‘graphic information, responses to the NEO-4 items, and
three simple validity checks. Respondents mark their
responses on the top sheet; the bottom sheet, which records
‘these marks, can easily be scored for the 24 facets in about
5 minutes.
‘The NEO-4 profile form presents personality data in the
familiar NEO profile format. Raw scores can be directly
plotted on the profile form to yield T scores (with a mean
of 50 and a standard deviation of 10). The four domain
scores are plotted on the left hand side of the form to give
an overview of the individual’s personality; the 24 facet
scales, grouped by domain, follow. The norms on the Form
S side of the profile form are based on the adult combined-
gender Form S norms of the NEO,PR (Costa & McCrae,
1992a, Table B-1). The other side of the profile form pre-
sents T scores for the combined-gender Form R norms
(Costa & McCrae, 1992a, Table B-2)
& scanned with OKEN ScannerA novel feature of the NEO-4 is the set of six style
four domain pairs. The six style
phe are included in the Style Graph Booklet. The
‘Rapondent’s location on cach graph is determined by plot=
ting 7 scores from the two domains. The graph contains &
escription ofthe styles of individuals who fallin one of
the four quadrants. These graphs call attention to combina-
tions of traits that are not emphasized in the profile forms;
they may also be used to plot the locations of a group of
individuals—for example, members of a work team—to
hhjghlight how the group members may complement or
‘conflict with each other with respect to attitudes, interper=
‘sonal styles, and so on. Interpretation of the style graphs

e lity Styles.
Feedback to the respondent can also be given using:
‘Your NEO-4 Summary. This is a version of Your NEO.
‘Summary, which has been used extensively to give respon-
dents feedback about NEO PLR scores. The front page
explains the respondent’s general standing on the four
domains; the back page shows the respondent's typical
styles of learning, interaction, and so on.

Missing Responses:
Respondents are instructed to answer each item, using
the neutral response option if they are unsure of how to
respond, Occasional missing items can be replaced by neu-

Validity Checks
‘The validity of scores on any personality questionnaire
depends chiefly on the honesty, care, and cooperation of
the test respondent, and the administrator’s major efforts
should be devoted toward maximizing valid responding,
Some checks on validity are built into the NEO-4, but they
are regarded mainly as indicators thatthe responses
be viewed with caution. Rather than simply discard poten-
tially invalid tests, administrators are urged to review the
issues with the respondent and to make an informed judg-
‘ment about whether the pattern of responses as a
merits discarding the test.

full. There is no cutoff point to distinguish people who
“have” or “do not have” the trait; rather, people differ in the
degree to which they can be characterized by the trait.
Norms
Norms for the NEO-4 are taken from the combined
gender normative sample of the NEO PLR. These com-
bined-gender norms are used-in the NEO-4 profile form
(Form $ and Form R). The normative sample of 1,000 men
‘and women was derived from participants in the Baltimore
Longitudinal Study of Aging (Shock et al., 1984) and from
sample of men and women in a national study of job per-
formance (Costa, McCrae, & Dye, 1991). From an initial
pool of 2,273 adults, 500 men and 500 women were cho:
sen to match 1995 U.S. Census projections for age (over
21) and race (White, Black, and Other). However, the sam-
ple was better educated than the general American popula-
tion; almost all participants were high school graduates.

NEO PLR manual.)

‘The NEO-4 Model
The NEO-4 operationalizes a hierarchical model of per-
sonality, in which broad personality factors (or domains)
are estimated from a series of specific traits (or facets). The
four NEO-4 domains are part of the B
Five model that
has been extensively discussed in the recent personality lit
erature (Digman, 1990; Goldberg, 1992; McCrae & John,
1992), ‘The NEO-4 facets have been described in a number
of publications (eg., Costa & MeCrae, 1995, in press;
Costa, McCrae, & Dembroski, 1989; Costa, McCrae, &
Dye, 1991); descriptions of the domains and facets and
npirical evidence regarding their construct validity are
presented at length in the NEO PL-R manual. As a quick
reference, however, Tables | to 4 summarize characteris
ties of high and low scorers for the 24 NEO-4 facets. These
summary tables are also available as overhead transparen
cies, which may be used by workshop facilitators or train
cers fo present facet-level interpretation of NEO-4 scores.
Interpreting Personality Styles
Personality traits interact with each other and with other
features of the person and his or her environment to
account for the individual's actions and experiences, Broad
personality factors are particularly pervasive influences,
and combinations of factors provide insight into major
aspects of people's lives, defining what can be called per-
sonality styles. For many years, psychologists have noted
that interpersonal interactions can be conceptualized in
terms of a circular ordering or circumplex, defined by the
two axes of Dominance versus Submission and Love ver-
sus Hate (Wiggins, 1979). Regarded as personality traits,
these two axes are intermediate hetween the two personal-
ity factors of Extraversion and Agreeableness (McCrae &
Costa, 1989b). E and A thus define a personal style that is
directly relevant to interpersonal relations; here it is called
Style of Interactions.
Although they are Jess well known, five other personal
styles (i.e. defined by other pairs of factors) are also useful
