THE
CLINICAL INTERVIEW
DEFINITION
OF INTERVIEW
A
situation of primarily vocal
communication, more or less voluntarily
integrated, on a progressively
unfolding
expert-client basis for the
purpose of elucidating characteristic patterns of
living of the
patients,
client, or subject, which pattern
he/she experiences as particularly
troublesome or especially
valuable,
and in the revealing of which he expects
to derive benefit..
According
to "Bingham" and "Moore" The
clinical interview is a conversation
with a purpose but as
the
purpose
differ the area of the interview
also differs.
INTRODUCTION
OF INTERVIEW
Almost
all professions count interviewing as
chief technique for
gathering data and making
decisions.
For
politicians, consumers, psychiatrists, employers, or
people in general, interviewing has
always been
a
major tool. As with any
activity that is engaged in
frequently, people sometime
take interview for
granted
or believe that it involve no special
skills; they can easily
overestimate their understanding
of
the
interview process. Although
many people seem awed by the
mystique of projective tests
or
impressed
by the psychometric intricacies of objective
tests.
The
assessment interview is at once
the most basic and the most
serviceable technique used by the
clinical
psychologists. In the hands of a skilled
clinician, its wide range of
applications and adoptability
make
it a major instrument for
clinical decision making,
understanding, and predictions. But
for all this,
we
must not lose sight of
the fact that the
clinical interview is not greater
than the skill and sensitivity
of
clinicians
who use it.
IMPORTANT
THINGS TO KNOW ABOUT CLINICAL
INTERVIEWS
1.
It is not a cross-examination but rather a
process during which the
interviewer must be aware of
the
client's
voice intonation, rate of
speech, as well as non-verbal
messages such as facial
expression,
posture,
and gestures.
2.
Although it is sometimes used as
the sole method if assessment, it is more
often used along
with
several
of the other methods.
3.
It serves as the basic context
for almost all other
psychological assessments.
4.
It is t he most widely used
clinical assessment
method.

TYPES
OF INTERVIEW
There
are many different forms of
interviews conducted by psychologists. Some
interviews are
conducted
prior to admission to a clinic or
hospital, some are conducted to determine
if a patient is in
danger
of injuring themselves or someone
else, some are conducted to
determine a diagnosis. Whereas
some
Interviews are highly structured
with specific questions asked
for all patients, others
are
unstructured
and spontaneous. In this section the common
forms of clinical interviews
will be briefly
discussed.
Some important forms of interview
are:
·
The
intake / admission interview
·
The
case history interview
·
Mental
status examination interview
·
The
crisis interview
·
Diagnostic
interview
·
Structured
interview
THE
INTAKE/ADMISSION INTERVIEW
According
to Watson;
"This
type of interview is usually
concerned with clarification of the
patient's percentage
complaints,
the
steps he has taken
previously to resolve his difficulties
and his expectances in regard to
what may be
done
for him".
The
purpose of the initial intake
interview or admission interview is to
develop a better understanding
of
the
patient's symptoms or concerns in
order to recommend the most
appropriate treatment or
intervention
plan. Whether the interview is conducted
for admission to a hospital, an
outpatient clinic, a
private
practice, or some other setting the
initial interview attempts to
evaluate the patient's situation
as
efficiently
as possible.
Ordinarily
a psychiatric social worker conducts
this interview; however,
upon occasion, the
psychologist,
one of the physician, or a psychiatric
nurse may serve as intake
interviewer. The
basic
question
to be dealt with is "Why is the
patient here? i.e., what
doe she says is the matter
with him?
Important
but secondary questions involve
information about previous
hospitalization, the name of
his
doctors,
what the patient expect from treatment,
his availability for treatment, and the
like.
Although
typically brief, the intake or admission
interview is extremely important in
conserving the
time
of other professional staff
members and in sparing the clinic or
hospital for occasional
embarrassing
or awkward situations. The
patient may in some
instances desire treatment which
a
particular
clinic may not be prepared to
give. Certain hospitals, for
example, do not handle
alcoholic or
narcotic
addiction cases; thus the
patient can be at once
referred to an appropriate institution,
saving
time
for the examining psychiatrist,
psychologist, the various attendants, and
for the patient
himself.
Similarly,
the awkward consequences of an overly
casual admission procedure can be avoided
by a well
planned
interview. Hospital staff
members can relate many
anecdotes of relative's who were
mistaken
for
the patient himself, of surgical
patient who were given
diagnostic psychiatric interview, or
of
salesman
who were escorted to a room and
confronted with a personality
test.
A
careful intake interview
will guard against such
mistakes. It should be noted
that every patient
will
not
be able to state coherently
what the nature of his trouble
may be. But even the unclear
replies can be
126
Clinical
Psychology (PSY401)
VU
highly
revealing, and the astute intake
interviewer can report
significant observation of the
patient's
behavior
which he may not reveal
again for some time or
which may be missed by later
examiners.
Ordinarily,
the diagnostic and treatment session
which come at some time
after the intake interview
are
carried
out by another, different
staff person. This does
not mean however, that
therapy begins later.
The
formal
label of "psychotherapy" it is true, is
given to the later procedures,
but real therapy, in the
sense
of
patient's attitude and his
motivation to get well, begins at the
time of the patient's admittance. It is
no
exaggeration
to assert that a bungled
intake interview prolong treatment
while an effective one
can
shorten
it.
CASE
HISTORY INTERVIEW
In
many hospitals and clinics the intake or
admission interview is followed
immediately by the personal
and
social history interview.
The same person usually a
psychiatric social worker, commonly
conduct
both
interviews, often in one sitting.
Sources of information other
then the patient himself
are, of course,
utilized
when completing a personal and social
history report. Frequently, the
patient does not
remember
or
can not for other
reasons communicate material which
may have a bearing upon his
problem. Thus,
information
from friends, relatives,
hospital, military, and
other records are also
used for the history.
But
whatever
the source of information, the purposes
of the social and personal history
report is to gather
information
which will be helpful in
diagnosing and treating the patient's
disorder.
Frequent
job changes, for example,
may be evidence of general instability.
The adult schizophrenic
who
showed
marked apathy and withdrawal
symptoms as a preschool child is probably
more severely
afflicted
than patients whom symptoms
appeared more recently. Neurotic
symptoms which appear
after
the
divorce of parents may have
different etiology than
similar symptoms which
appear after the head
injury.
In
most instances a standardized form or
social history guide of some sort is
used. There are
advantages
in
using a standardized printed form, as
Louttite has noted in that
pertinent information will
not be
skipped;
however as he also notes, a
rigid dependency upon the form
may ensue. Certain
obvious
information
may not be recorded because the
form does not call
for it or details which are
unimportant
for
a particular case may be set
down in time wasting
abundance. Obviously the common sense of
the
interviewer
is the answer to such problems.
The
typical information obtained in a
personal and social history includes
material on the patient's
early
life,
with particular attention
paid to family relationship and general
environment. Also included
are
data
on the patient's educational and
vocational history, neuropathic
traits, his habits and recreations,
as
well
as other material. Obviously
much of this information can
be obtained only by direct
questioning.
Some
patients are threatened by situations
which require specific
answers, and they may show
panic
reactions
of varying degree. Others
will lie, perhaps because
they cannot remember and do not
wish to
say
so, but more often because
painful memories are awakened of
jail sentences, of divorce, of
previous
hospitalization,
or the like. Most patients, of course,
are truthful, but only in
their cultural
fashion.
It
is this area that the skill
of the interviewer is brought
out. While much of the
information requested is
factual,
the manner in which the patient
communicates his facts may
be quite misleading.
The
fact that an occasional patient
will lie about his personal
social history, even about
trivial matters, is
sometimes
irritating or disheartening to the newcomer to the
interviewing situation. Such
falsification is
not
a reflection upon the interviewer's
skill or comportment but rather upon the
reason why the
patient
is
being interviewed. He is a patient. He
may be confused, a psychopath, or something else;
but he is
sick.
This may seem like
unnecessary emphasis; yet
every clinician should be prepared to
ward off
feelings
of indignation or humiliation which
may arise when he learns
that virtually every fact he
so
laboriously
recorded, from age and
address to family history
and vocation, is false. This
happens with
extreme
rarity, of course; but it happen to
almost every clinician sooner or
later. When it does, and
if
127
Clinical
Psychology (PSY401)
VU
one
is taken in, a little self
directed humor helps restore a
sense of proportion. Then a
firm resolution to
check
other information sources
can turn the experiences to
one's advantage.
MENTAL
STATUS EXAMINATION
INTERVIEW
Often
a mental status examination
interview is conducted to screen the
patient's level of
psychological
functioning
and the presence or absence of
abnormal mental phenomena
such as delusions, delirium, or
dementia.
Mental status exams include
a brief evaluation and observation of the
patient's appearance
and
manner, speech characteristics, mood,
thought processes, insight,
judgment, attention,
concentration,
memory, and
orientation.
Results
from the mental status
examination provide preliminary
information about the likely
psychiatric
diagnosis
experienced by the patient as well as
offering some direction for
further assessment and
intervention
(e.g. referred to a specialist, admission to
psychiatric unit, and evaluation
for medical
problems
that impact psychological
functioning). For instance,
mental status interviews
typically
include
questions and tasks to determine
orientation to time (e.g., "what
day is it? What month is
it?),
place
(e.g., Where are you now?
Which hospital are you
in?"), and person ("who am I
who is the
president
of United States?"). Also, the mental
status interview asses short
term memory (e.g. "I am
going
to name three objects I'd like you to
try and remember: dog,
pencil, and vase") and
attention-
concentration
(e.g., "count down by 7s starting at
100. For example 100,
93, and so forth").
While
there are some mental status
examination that are structured
resulting in scores that can
be
compared
to national norms, most are
unstructured and do not offer a scoring
or norming option.
During
the
examination the interviewer notes
any unusual behavior or answers to
questions that might be
indicative
or psychiatric disturbance. For example,
being unaware of the month, year, or the
name of the
current
president of the United States usually
indicate mental problems. This
can result in bias based
on
the
interviewer's clinical judgment
during and evaluation.
THE
CRISIS INTERVIEW
A
crisis interview occur when the patient
is in the middle of a significant and
often traumatic or
life
threatening
crisis. The psychologists or the mental
health professionals (e.g., a trained
volunteer) might
encounter
such a situation while
working at a suicide or poison
control hotline, an emergency room,
a
community
mental health clinic, a student
health service on campus, or in many
other settings. The
nature
of the emergency dictates a rapid, "get to the
point" style of interview as
well as quick
decision
making
in the context of a calming style.
For example, it may be
critical to determine whether
the
person
is at significant risk of hurting
him- or herself or others. Or it may be
important to determine
whether
the alcohol, drugs, or any other
substances are used, so as to
make sure that the
clinician
interviews
the person in a calming and clear headed
manner while asking critical
questions in order to
deal
with the situation
effectively.
The
interviewer may need to be more
directive (e.g., encouraging the person
to phone the police, unload
a
gun, provide instructions to
induce vomiting, or step
away from a tall building or
bridge); break
confidentiality
if the person (or someone
else, such as a child) is in
serious and immediate danger;
or
enlist
the help of others (e.g., police
department, ambulance).
THE
DIAGNOSTIC INTERVIEW
The
purpose of the screening or diagnostic
interview is to assist the clinician in
his attempt to
understand
the patient.
If
the level of diagnostic understanding
required is merely a separation of the
fit from the unfit, as
in
military
neuro-psychiatric examinations, the
interview task is one of screening. That
is, after a brief
interview
the interviewee be adjusted fit for
specific duties, such as a regular
military assignment, or he
may
be referred for prolonged
observation and extended psychological
testing. Occasionally, limit
or
128
Clinical
Psychology (PSY401)
VU
trial
duty may be recommended as an
alternative to regular duty of
psychological observation.
Upon
other
occasions the diagnostic task is
highly specific, and a detailed
level of understanding is
required.
This
may involve a diagnostic
label as categorized as "paranoid
schizophrenia" and a description
of
personality
dynamics. In the later case primary
dependence is not placed upon the
interview alone, for
psychological
tests play a most important
role in such detailed
diagnostic procedures.
In
the diagnostic interview, while the
examination progresses; the interviewer
observes the
interviewee's
behavior as well as noticing the content
of his answers. Thus thighs
pressed together, a
mincing
walk, and fluttery feminine
gestures in a male should lead the
interviewer to suspect and
investigate
the possibility of homosexuality. The
bubbling, enthusiastic replies and exaggerated
gestures
in
another interview should lead the
interviewer to hypothesize tentatively a manic
condition and seek
further
evidence. Similarly, as Wittson, et al.
noted, the psychopath often gives
evidence of his deviation
by
his utter impersonality or even
belligerence towards the
interviewer.
Ordinarily,
brief neuro psychiatric
interviews are not oriented
towards future psychotherapeutic
activity
because
most of the interviews have no need of
therapy. However, it is not
difficult to adopt the
procedure
of the brief interviews so that
those who seem in need of
treatment are rendered more
receptive
to the idea. Thus this kind
of interview is used to describe
that whether an individual
needs
help
or not.
STRUCTURED
INTERVIEW
In
an effort to increase the reliability and
validity of clinical interviews, a number
of structured
interviews
have been developed. These
interviews include very
specific questions asked in a
detailed
flow
chart format. The goal is to
obtain necessary information, to make an
appropriate diagnosis, to
determine
whether a patient is appropriate
for a specific treatment or research
program, and to
secure
critical
data that are needed
for patient care. The
questions are generally organized and
developed in a
decision
tree format. If a patient answers
yes to particular questions (for
example, about panic), the
list
of
additional questions might be asked to
obtain details and
clarification.
RELIABILTY
AND VALIDITY OF INTERVIEWS
As
with any form of
psychological assessment, it is important
to evaluate the reliability and validity
of
interviews.
RELIABILITY
The
reliability of an interview is typically
evaluated in terms of the levels of
agreement between at least
two
raters who evaluated the
same patients or client, by agreement we
mean consensus on diagnosis
assigned,
on ratings of levels of personality
traits, or any other type of
summary information
derived
from
an interview. This is often
referred as inter-rater
reliability.
Standardized
(structured) interviews with clear scoring
instructions will be more reliable
than
unstructured
interviews. The reason is
that structured interviews reduce
both information variance
and
criterion
variance. Information variance refers to
the variation in the question that
clinicians ask, the
observations
that are made during the
interview, and the method of integrating the
information that is
obtained.
Criterion variance refers to variations
in scoring thresholds among clinicians.
Another
type of reliability is the test-retest
interviews-the consistency of scores or
diagnoses across
time.
We expect the test re test reliability of
an interview quite high when
the intervening time
period
between
the initial testing and the retest
testing is short. However when the
intervening time period
is
long
test retest reliability
suffers.
129
Clinical
Psychology (PSY401)
VU
VALIDITY
The
validity of an interview concerns
how well the interview
measures what it is intended to
measure.
The
validity of any type of
psychological measures can
take many forms.
CONTENT
VALIDITY:-refers
to the measure's comprehensiveness in
assessing the variable of
interest.
In other words, does it do a good
job of adequately measuring all
important aspects of
the
construct
of interest?
CRITERION
RELATED VALIDITY:-refers to the
ability of a measure to predict
(correlate with)
scores
on other relevant measures.
These measures may be
administered concurrently with the
interview
(concurrent
validity) or at some point in the
future (predictive)
validity
DISCRIMINANT
VALIDITY:-refers
to the interview's ability to not
correlate with measures that
are
not
theoretically related to the construct
being measured.
CONSTRUCT
VALIDITY:-is
used to refer to all these
aspects of validity. Thus many
researchers
describe
the process of developing and validating
a measure as a process of construct
validity.
In
case of structured diagnostic interviews,
content validity is usually assumed,
because these
interviews
were
developed to measure the DSM
criteria for specific mental
disorders. That leaves us in need
for
validation
efforts aimed at establishing an
interview's criterion-related,
discriminant, and construct
validity.
SUGGESTIONS
TO IMPROVE RELIABILTY AND
VALIDITY
1.
Whenever possible use a structured
interview.
2.
If a structured interview does not
exist for your purpose,
consider developing one.
3.
Whether you are using a
structured or unstructured interview, certain
interviewing skills are
essential.
4.
Be aware of the patient's motives
and expectancies with regard to the
interview.
5.
Be aware of your expectations, biases,
and cultural values.
FACTORS
THAT INFLUENCE INTERVIEWS
Many
factors influence on the productivity and
utility of data obtained
from interview. Some involve
the
physical
setting. Others are related
to the nature of the patient. A mature
communicative patient may
not
cooperate
regardless of the level of the
interviewer's skill. Few
interviewers are effective
with every
patient.
Several factors or skills, however, can
increase the likelihood that
interviews will be
productive.
Training
and supervised experiences in interviewing
are very important.
Techniques that work well
for
one
interview can be notably
less effective for another;
there is crucial interaction between
techniques
and
interviewer. This is why
gaining experience in a supervised setting is so
important; it enables the
interviewer
to achieve some awareness of the nature of
this interaction. Training,
then, involves not
just
a
simple memorization of rules, but
rather, a growing knowledge of the
relationships among rules, the
concrete
situation being confronted,
and one's own impact in
interview situation.
1.THE
PHYSICAL SETTING
An
interview can be conducted any where
that the two people can
meet and interact. The
best
interviewing
conditions are characterized by privacy,
freedom from interruption, and
some control of
both
inside and out side sounds.
Nothing is more damaging to the
continuity of an interview then
a
130
Clinical
Psychology (PSY401)
VU
phone
that rings relentlessly, a secretary's
query, or an imperative knock on the
door. Such
interruptions
are
extremely disruptive.
The
general appearance of the room should
suggest comfort and yet have a
professional flavor about
it.
2.
NOTE-TAKING AND RECORDING
All
contacts with the client
ultimately need to be documented.
However, there is some debate
over
whether
notes should be taken during
an interview. Although there are
few absolutes, in general, it
would
seem desirable to take occasional notes
during an interview. A few
key phrases jotted down
will
help
the clinicians to recall. Most
clinicians have had the experience of feeling
that the material in an
interview
is so important that there is no need to
take notes. The material
will easily be
remembered.
However,
after having a few
additional patients the clinicians cannot be
able to recall much for
their
earlier
interview. Therefore, a moderate amount
of note - taking seems
worthwhile. Most patients
will
not
be troubled by it, and if one should
be, the topic can be
discussed.
However,
any attempt at taking verbatim
note should be avoided. One
danger in taking verbatim is
that
this
practice may prevent the clinicians
from attending fully to the
essence of the
patient's
verbalizations.
An overriding compulsion to get it all
down can detract from a
genuine understanding of
the
nuances and significance of the
patient's remarks. In addition,
excessive note taking tends
to prevent
the
clinicians from observing the
patient and from noting subtle
changes of expression or slight
changes
in
body position.
With
today's technology, it is easy to
audio tape or videotape
interviews. Under no
circumstances
should
be this done with out the
patient' fully informed
consent.
3.RAPPORT
Report
is the word often used to
characterize the relationship between
patient and clinician.
Rapport
involves
a comfortable atmosphere and a mutual
understanding of the purpose of the
interview. Good
rapport
can be primary instrument by
which the clinicians achieve the purpose
of the interview. A cold,
hostile
or adversarial relationship is not
likely to be constructive. Although a
positive atmosphere is
certainly
not the sole ingredient for
a productive interview, it is usually a
necessary one. Whatever
skills
the
interviewer possess will
surely be rendered more effective in
proportion to the interview's
capacity
to
establish a positive relationship.
4.
SETTING THE RIGHT
TONE
Experienced
interviewers have learned and repeatedly
confirmed that the atmosphere
most conducive to
the
successful elicitation of information is
one of mutual respect.
5.
GETTING THE INTERVIEW OFF TO
A GOD START
One
of the first tasks, in fact,
obligations, of the clinician is to make
sure that the client
understands the
purpose
of the interview as clearly as he is
capable of understanding.
COMPONENTS
OF GOOD LISTENING
-elimination
of distraction
-alertness
131
Clinical
Psychology (PSY401)
VU
-concentration
-patience
-Open-mindedness
6.
ADJUSTMENT
Adjust
the sequence of topics to be discussed to the
anxiety level of the
informant.
7.
MOVING RAPIDLY THROUGH THE
INTERVIEW
In
personal interviewing and, even more important, in
case history interviewing a
rapid fire technique
may
result in grater reliability.
8.
ASKING QUESTIONS
STRAIGHTFORWARDLY
Johnson,
et al., remarked, having laid a
solid foundation of rapport,
mutual understanding and respect,
it
is
best to ask questions in a direct
manner.
9.
CONSIDERABLE TACT AND SKILL MUST BE
USED IN HANDLING
PAUSES
We
should not be too eager to
make and answer for a client
and should give him time to
think through
his
answer carefully. On the other hand, we
must not allow pauses to
become so long as to
become
painful
or awkward and this make the
client uncomfortable.
10.ATTEPMT
TO GET BENEATH SUPERFICAL
ANSWER
We
should attempt to rephrase or ask
additional questions when client's
answers are obviously
superficial.
11.
NOTE DISCRIPANCIES IN THE
ACCOUNT AND CHECK THEM
When
inconsistencies are noted, they
should not be ignored, but
should be checked as unobtrusively
as
possible
without challenging the client's
veracity.
12.
HANDLING EMOTIONAL SCENES
TACTFULLY
A
moderate amount of crying, weeping,
anger, or hostility is to be expected and is
frequently of sign a
good
rapport. However it is responsibility of
the clinician to maintain control of the
situation and not to
allow
it to get out of hand, or the client to
become too depressed.
13.
PREPAREDNESS
Be
prepared for the questions directed to
you by the informant. Clinician's
answer will depend upon
his
role
in clinic routine i.e., what
his answers will mean in
terms of helping or hindering the
progress of the
interview.
POTENTIAL
THREATS OF EFFECTIVE
INTERVIEWING
BIASNESS
Interviewers
may be biased. Their
personality, theoretical orientation,
interests, values, previous
experiences,
cultural background, and other factors
may influence how they
conduct an interview, what
they
attend to, and what they conclude.
Interviewers may consciously or
unconsciously distort
132
Clinical
Psychology (PSY401)
VU
information
collected during an interview
based on their own slant on the
patient or the patient's
problems.
For
example, a psychologist is an expert on
child sexual abuse. She
treats children who have
been
sexually
abused as children and publishes
professional articles and books on the topic.
She is often
asked
to give lectures around the
country on the subject. When a patient
describes symptoms
often
associated
with child sexual abuse such
as depression, anxiety, low
self esteem, relationship
conflicts,
and
sexually concerns, the psychologists
assume that the symptoms are
associated with sexual
abuse.
When
a patient denies any experience of sexual
abuse, the psychologist assumes
that the patient has
repressed
or forgotten the traumatic memory.
She then works to help the
patient uncover the
repressed
memory
in order to realize that
they have been abused.
Clearly, this example
illustrates how bias
can
lead
to distorted or even destructive
approaches.
RELIABILITY
AND VALIDITY
Reliability
and validity may also be
threatened. For example, if two or more
interviewers conduct
independent
interviews with a patient,
they may or may not end up
with the same diagnosis,
hypothesis,
and
treatment plans. Further more; patients may
not report the same
information when questioned
may
be
several different interviews. Interviewer
gender, race, age, and
skill level are some of the
factors that
may
affect patient response
during an interview (Grantham,
1973).
Emotional
level may also have an
impact on reporting of information.
For example, personal questions
regarding
sexual behavior, alcohol use,
child abuse, or other sensitive
issues may elicit
varying
responses
from patients under different
circumstances. Reliability and validity
may be enhanced by
using
structured interviews, asking similar
questions in different ways, using
multiple interviewers, and
supplementing
interview information from
other sources (e.g., medical
records, observers,
questionnaires).
