ASSESSMENT
of PERSONALITY
Personality
Inventories
Personality
inventories present an elaborate picture of an
individual's overall personality
including the traits,
the
characteristics, the tendency and the
styles that are thought to
underlie behavior.
The
questions in personality inventories are
presented in form of statements.
These statements are the
items
of
personality test. Many personality inventories
are available such as MMPI
Minnesota Multiphasic
Personality
Inventory. This test was
develop in 1940 and published in 1943. It
is based on empirical
approach
i.e. the collection and evaluation of
data. The individual is
presented with statements
and the
answers
have options like true,
false and cannot say. Some
of the statements from MMPI are
following:
·
I
cry easily
·
I am happy
most of the time.
·
I
believe, I am being followed
MMPI
consisted of 550 items. MMPI
consists of ten clinical scales, meaning
that it diagnosis people on ten
clinical
disorders. It has got four
validity scales, which
include:
1.
Lie scale
2.
The F Scale, Infrequency
scale
3.
K scale, The Defensiveness
Scale
4.
The Can not say
scale
·
They
consist of a series of straightforward
statements; the person being tested is
typically required
to
indicate whether each statement is true or
false in relation to an
individual.
·
Some
personality inventories are designed to
identify personality traits in a normal population,
and
others
focus more specifically on
psychological problems.
·
The
most extensively used personality
Inventory is the Minnesota Multiphasic
Personality
Inventory
(MMPI). The inventory was
revised several years ago,
and it is currently known as the
MMPI-2.
·
The
MMPI-2 is based on 567
statements that cover topics
ranging from physical complaints
and
psychological
states to occupational preferences and
social attitudes. Scoring of the
MMPI-2 is
objective.
·
After
the responses to all questions
are totaled, the person receives a
numerical score on each of
10
clinical
scales as well as on four
validities.
The
MMPI not only diagnoses a
person on ten clinical scales it also
detects sources of invalidities
like lying,
carelessness,
defensiveness on part of respondent. It
attempts to present all
information in form of a
profile
of
scores. This profile of
scores across all ten clinical
scales and four validity
scales is presented as
deviations
from general population
norms. The normal scale
score is a T-score of 50 any
score above 50 is
a
sign of pathology.

·
Before
considering the possible clinical
significance of a person's MMPI-2
profile, the psychologist
will
examine a number of validity scales,
which reflect the patient's attitude
toward the test and
the
openness
and consistency with which
the questions were
answered.
·
The
L (Lie) Scale is sensitive to
unsophisticated attempts to avoid
answering in a frank and
honest
manner.
·
Examples
of items of MMPI 2
1.
I like automobile
magazines.
2.
I wake up with lots of energy
most mornings.
3.
I am startled by loud
noises.
Advantages
of MMPI-2
1.
The MMPI-2 provides information
about the person's test-taking attitude,
which alerts the clinician
to
the possibility that clients
are careless, defensive, or
exaggerating their
problems.
2.
The MMPI-2 covers a wide
range of problems in a direct and
efficient manner
82
Abnormal
Psychology PSY404
VU
3.
Because the MMPI-2 is scored
objectively, the initial description of the
person's adjustment is
not
influenced
by the clinician's subjective impression
of the client.
4.
The MMPI-2 can be
interpreted in an actuarial fashion,
using extensive banks of
information
regarding
people who respond to items in a
particular way.
Limitations
of MMPI-2
1.
The test is not particularly
sensitive to certain forms of psychopathology,
especially those that
have
been
added with the publication of
DSM-III and
DSM-IV-TR.
2.
The test depends on the
person's ability to read and
respond to written
statements.
Other
Self-Report Inventories
·
Many
other questionnaires and
checklists have been developed to collect
information about
adjustment
problems, including subjective
mood states such as
depression and anxiety, patterns
of
obsessive
thinking, and attitudes about drinking
alcohol, eating, and sexual
behavior.
·
The
format of most self-report inventories is
similar to that employed
with objective personality
tests
like the MMPI-2.
·
The
primary difference is the range of topics
covered by the instrument.
·
Self-report
inventories usually don't include
validity scales, and they
may not be standardized
on
large
samples of normal subjects prior to
their use in a clinical
setting.
·
Self-report
inventories offer many advantages as
supplements to information that is
collected
during
clinical interviews.
·
Self-report
inventories can lead to serious
problems if they are used
carelessly.
Intelligence
Tests
What
is intelligence? What is IQ and
how are intelligence tests
important in psychopathology?
Intelligence
refers
to your overall adjustment. IQ is
your intelligence quotient score
which refers to intelligence
level.
·
IQ is
your intelligence quotient .IQ
refers to a score on an intelligence
test.
·
Intelligence
can be measured by
·
Puzzles
and riddles you can
solve
·
Difficult
questions you can correctly
answer
·
Standardized
intelligence tests
·
Intelligence
tests developed for one
specific purpose to predict who
will do well in school. In
1904,
a
French psychologist Alfred
Binet and Theodore Simon
were commissioned by the
French
government
to identify slow learners in
class to benefit from
remedial help. They developed the
intelligence
test that was designed to
predict academic success. The
test provided a known
as
intelligence
quotient, or IQ. The IQ is
calculated by
·
IQ= MA/CA X
100
·
A
child who passed all
items on the test of 8 year
old gets a mental age of 8
where as the actual
age
of
the child may be 6years now
put these values in the
formula
·
IQ=
8/6X 100=
Otis
Quick Scoring Mental Ability
Test
Otis
quick scoring mental ability
test consists of 80 items
which relates to general
intelligence,
vocabulary,
arithmetic ability and general knowledge.
The test is a speeded test
i.e. the number
of
items is large and the time
allotted is short and no one
can finish the test in time.
Power test
is
a test which has no time constraint
but some of the items in the
test are so difficult that
no
one
can correctly respond to
them.
Wechsler
Intelligence Scales

David
Wechsler introduced Wechsler
Preschool And Primary Scale
of Intelligence Revised
(WPPSI-R)
intelligence scale for preschool
children for kinder-
garden.
·
He
gave the WECHSLER INTELLIGENCE
SCALE FOR CHILDREN
(WISC-III).

·
He
introduced WECHSLER ADULT INTELLIGENCE
SCALE (WAIS-III).
·
Both
the scales consist of 11 sub
tests measuring the intelligence level of
children and adults.
·
All
these tests have verbal
scales and performance
scales.
·
The
verbal scales measure vocabulary, knowledge of
facts, short term memory and
verbal
reasoning.
·
The
performance scales assess psycho-motor
abilities, nonverbal reasoning and
ability to learn new
relations.
·
Intelligence
tests are reliable measures of
academic success
·
In
abnormal psychology we use these
tests to measure cognitive impairment
(reflected in low IQ)
·
DELIRIUM
Mental
Retardation (Slow Learners)
Intelligence
test measures abilities such as
attention, perception, and memory,
reasoning and verbal
comprehension.
Intelligence measures the ability of an
individual to adapt to the environment,
the ability to
generate
new ideas and the ability to
process information
efficiently.
Projective
Personality Tests
Psychoanalytic
personality theorists have developed
several assessment measures
known as projective
tests.
They
include a variety of methods in which
ambiguous stimuli, such as pictures of
people, or things are
presented
to a person who is asked to
describe what he or she sees.
The theory here is that
people `project'
their
own personality, their needs,
their wishes, their desires
and their unconscious fears
on other people
and
things such as ink blots, pictures,
sometimes vague and
sometimes structure. Projective tests
are based
on
psychoanalytic theory. They have
been and they still remain,
controversial. Some of the most widely
used
projective
tests are Rorschach Ink
Blot Test, the Thematic Apperception
Test (TAT), House Tree
Person
(HTP)
and the Rotter's Incomplete Sentence
Blank (RISB).
·
In
projective
tests, the
person is presented with a
series of ambiguous stimuli.
·
The
known projective test,
introduced in 1921 by Hermann
Rorschach,
a Swiss psychiatrist, is
based
on the use of inkblots.
·
Projective
techniques such as the Rorschach
test were originally based
on psychodynamic
assumptions
about the nature of personality and
psychopathology.
·
Considerable
emphasis was placed on the importance of
unconscious motivations --conflicts
and
impulses
of which the person is largely
unaware.
·
More
recent approaches to the use of
projective tests view the
person's descriptions of the cards
as
a
sample of his or her perceptual
and cognitive styles. This
test consists of ten standardized
ink
blots.
That serves as ambiguous stimuli.
The examiner presents the
inkblots one by one to
the
person
being examined, who responds by
telling what he or she sees.
The therapists may
encourage
the
subject to give more detailed
answers and you may
get different responses on the
same inkblot.
Exner's
system of administering and scoring the
Rorschach inkblot test
specifies how the
card
should
be presented, what should the examiner
say and how the responses
should be recorded.
·
The
Thematic Apperception Test (TAT)
consists of a series of drawings
that depict human
figures
in
various ambiguous
situations.
·
The
person is asked to describe the
identities of the people in the cards and to
make up a story
about
what is happening. Morgan and Murray at
the Harvard Psychological Clinic
developed the
TAT.
It consists of 31 cards, 30 with
pictures on them and one
blank card. The picture card
is
shown
to the subject and the therapist asks the
subject to tell a dramatic story about
the picture.
The
instructions of the test begin `this is a
test of imagination, one form of
intelligence. Let your
imaginations
have its way as in a fairy
story and tell what the people in the picture
card are doing.'
The
story should have a title, a beginning, a middle
part and an end. The
basic assumption is
that
most
of the subjects will reveal
their unconscious mental
processes, their needs,
desires on the
characters
of their stories about the pictures.
Their have been several
variations of the TAT for
different
groups e.g. CAT- Children
Apperception Test and SAT A
Senior Apperception
Technique.

Rotter's
Incomplete Sentence Blank
Test
This
test consists of a series
unfinished sentences that people
are asked to complete,
usually it is considered
a
good spring board to explore and
pinpoint areas of an individual's
life that are problematic or
conflicting.
The
sentences are usually, I
wish _____. My father is
______. Girls are _____.
Home is a place
________.
This
test explores an individual's
social, familial and general
attitudes towards life. This
test has 40 items
which
are in form of incomplete sentences.
This test has qualitative
and quantitative scoring
procedures.
House
Tree and Person
(HTP)
This
is a test which tells us about the
evaluations of the drawings based on the
quality and shape of
the
drawing, solidity of a pencil line, location of the
drawing on the paper, the size of the figure, features
of
the
figures, use of the background and
comments made by the respondent
during the drawing task.
The
house
reflects individual's interpersonal
relationships, the tree reflects
ego development and functioning
and
the
person reflects the individual
self perception and perception of the
other gender.
Advantages
of Projective Tests
1.
Some people may feel more comfortable
talking in an unstructured situation than they
would if
they
were required to participate in a structured
interview or to complete the lengthy
MMPI.
2.
Projective tests can provide an
interesting source of information
regarding the person's unique
view
of
the world, and they can be a
useful supplement to information obtained
with other assessment
tools.
3.
To whatever extent a person's relationships
with other people are governed by
unconscious
cognitive
and emotional events,
projective tests may provide
information that cannot be
obtained
through
direct interviewing methods or observational
procedures.
Limitations
of Projective Tests
1.
Lack of standardization in administration and scoring
is a serious problem.
2.
Little information is available on
which to base comparisons to
normal adults or children.
3.
Some projective procedures,
such as the Rorschach, can be very
time-consuming.
4.
The reliability of scoring
and interpretation tends to be
low.
5.
Many self-report inventories, rating scales,
and behavioral coding systems have
been designed for
the
assessment of marital relationships and
family systems.
6.
One popular self-report inventory is the Family
Environment Scale (FES),
which is composed of
90
truefalse items and was
designed to measure the social
characteristics of families.
