CLINICAL INTERVIEW
1. DEFINITION
Interview is a face to face situation between
the interviewer and the respondent, which
intends to elicit some desired information
from the latter. Thus, interview is a social
process involving at least two persons, the
interviewer and the respondents.
1. Definition2. Stages & Types3. Factors influencing
The success of the interview depend upon
three conditions:
1. Accessibility
2. Cognition
3. Motivation
2. TYPES
Formal Interview
1. Can be defined as one in which already prepared questions are asked in a set order by the interviewer and answers are recorded in a standardized form.
2. Conducted in a uniform way
3. Structured/ Patterned interview
• Relatively less trained interviewer can also
conduct the interview.
• Expensive and time consuming
Informal Interview
One where there are no predetermined questions
nor is there any preset order of the questions and
is left to the interviewer to ask some questions in
a way he likes regarding the no. of key points
around which the interview is to be built up.
• Unstructured interview
• Flexible method of collecting data
• Can “Dig deeper” and therefore get deeper
understanding of the respondents behaviour.
• Can have personal influence of the interviewer
• Requires greater skill on the part of the
interviewer.
Other Types Of Interview
• Semi structured• Prolonged • Brief • Spontaneous
CLINICAL INTERVIEW
1. Diagnostic interview
The information about the patient and family will be collected according to the case history Proforma
2. Intake/ Therapeutic interview
The client and family will be given orientation about the treatment/management after exploring their need, motivation and interest.
Types of interviews - Based on the Purpose/Process
3. Social history/ case history interview
The purpose is to get the information on his life,
current personal and social situations.
4. Interview with informants
This is for supplementing the information from
relatives, teachers, friends etc.
CLINICAL INTERVIEW
5. Consultation interview
Done by the consultant/supervisor in the teaching and training set up.
6. Screening interview
When the number of patients are more in the O.P.D. set up this type of brief interview needs to be carried out.
7. Discharge interview
• This will be carried out at the time of termination
/discharge of in- patient
3. STAGES
1. Opening phase
2. Middle phase
3. Final phase
CLINICAL INTERVIEWFactors influencing the interview
1. Communication and language
2. Non verbal communication
3. Socio cultural background of the client
4. Orientation & background of the clinician
5. Establishing the empathetic relation with the client
6. Place or set up for the interview
7. Co-operation of the informant
8. Co-operation of the client
9. Motivation of the client
CLINICAL INTERVIEW
Types of questions to be asked during interview –
1. Open ended questions
2. Leading questions
3. Directive questions
4. Forced choice questions
Observation
• Useful when the investigator wants to see the
behaviour in natural situation and study the
situation-based feature of conduct, such
situations questionnaires, interview are of
limited use.
Definition
Observation, as a fundamental technique of
data collection, refers to watching and
listening to the behaviour of other persons
over time without manipulating and
controlling it and record findings in ways
that allow some degree of analytical
interpretation and discussion.
• There is natural social context in which
persons behaviour is studied.
• It captures those significant events or
occurrences that affect the relations among
persons being studied.
Types:
1. Objective observation: Observation of the overt behaviors like speech, language, Fluency etc.
2. Subjective observation: Here the client observes his own behavior, which can’t be observed directly by others (Introspection).
3. Naturalistic observation: Objectively observing the behaviors in the natural set- up.
Example: Therapist observing the fluency of a person with stuttering in the classroom or in the shopping
35
Types contd….
• Systematic observation: one which is done
according to some explicit procedures as well as
in accordance with the logic of scientific
inference.
• Unsystematic observation: Inference made by
investigator without specifying any explicit and
objective inference.
Based on the role of the investigator:
• Participant Observation: Investigator actively participates in the activities of the group to be observed.
• May be the member of the group/ organization.
• Procedure of the investigator is unstructured and the usually the identity of the investigator is not known to the other members of the group.
• Observer is flexible to decide what to observe and how to record it.
• More meaningful and convincing conclusions.
• Broader aspect of the human behaviour is assessed.
• Time consuming.
• Influenced by the subjectivity of the observer.
• Non-participant observation: Observes the natural setting without becoming the member of the group to be observed.
• Usually structured.
• Observer preplans the likely nature of the natural setting, representatives of the data, problems associated with the presence of the investigator etc.
• because the observation is structured, results are more reliable.
• Not influenced by the subjectivity of the observer.
• Observer misses the important aspect of the group.
• Participants become conscious that they are being observed.
Definition of Psychological Testing
• "An objective and standardized measure of a
sample of behaviour" (Anastasi, 1990).
• Psychological assessment is defined as the
process of ‘systematic collection, organization
and interpretation of information about a person
and his situation’. (Sunderberg and Taylor,1962)
–Psychological tests are written, visual, or verbal
evaluations administered to assess the cognitive
and emotional functioning of children and adults.
–Psychological tests are used to assess a variety of
mental abilities and attributes, including
achievement and ability, personality etc.
• Psychological tests are formalized measures of
mental functioning. Also known as inventories,
measurements, questionnaires, and scales,
psychological tests are administered in a variety of
settings, including preschools, primary and
secondary schools, colleges and universities,
hospitals, outpatient healthcare settings, social
agencies, prisons, and employment or human
resource offices.
PSYCHOLOGICAL ASSESSMENT/TESTING
1. Assessment of Cognitive functions-
The functions are attention and concentration, perception, memory, intelligence, thinking and reasoning.
2. Assessment of personality and interpersonal relationship (Extrovert, introvert, ambivert, shy, tense, extravagant, outgoing etc.) 16 PF, California Psychological inventory.
3. Diagnostic assessments: Used for the diagnostic
purpose with the help of tests like- MPQ, Childhood
Autism Rating scale, Adolescent Psychopathology
Scale, Beck’s depression rating scale.
4. Neuropsychological assessments: Assessment of
brain behavior relationship – lateralization &
localization of functions & structures
5. Vocational assessments and assessments of
interests and Aptitudes. (Differential
aptitude test, Wide Range achievement test.)
6. Behavioral assessment – behavioral diagnosis
FACTORS INFLUENCING PSYCHOLOGICAL ASSESSMENT
1. Age –children/adolescence/adults/old aged
2. Education
3. Occupation – type/nature of the work
4. Sex
5. Socio- cultural background
6. Interest/ Motivation/ Co-operation
7. Physical or sensory impediments- visual/hearing/orthopedic
8. Theoretical orientation of the clinician
New terms
1. Classification: is a broad term, the action or process of classifying.
2. Taxonomy: (Chiefly Biology) the branch of science concerned with classification. Refers to the classification of entities like insects, rocks.
3. Nosology: the branch of medical sciences concerned with the classification of diseases.
4. Nomenclature: The term which describes the names or labels of the disorders.
HISTORY
• Egypt and Sumeria, two conditions – Melancholia & Hysteria were identified 2600 B.C.
• India, psychiatric nosology was contained within the medical classification system of Ayur-Veda written about 1400 B.C.
• Hippocrates & Plato - classified mental disorders in Greece based on empirical observation.
• European Renaissance, Carous Linneaus and Francois Boisser attempted to apply the taxonomic methods of biology to medical and psychiatric illness.
• Paradigms based on observation and theory continued during the 19th century
• Emil Krapelin - “Natural” classification in which, cause, symptomatology & course were expected, but finally the classification ended up with the inclusion of mainly symptoms.
HISTORY
• First modern attempt at classification was International list of causes of Death (1893).
• The first nosology of psychiatry - in USA by American Medico-Psychological association (1918) / American Psychiatric association - consisted 22 disorders
• In 1935, a standard classified nomenclature of disease was published.
• Following the World War II, WHO developed 6th
revision of “Manual of International Statistical
Classification of Disease, Injuries and Causes of Death -
1948 included psychiatric disorders for the first time.
• ICD 8 (1972) glossary
• ICD 9 (1978) glossary
• ICD 10 (1992) International Statistical classification of
diseases & related health problems
• Dissatisfied with ICD 6 The American
Psychiatric Association published
DSM 1 1952
DSM II 1968
DSM III 1980
DSM IIIR 1987
DSM IV 1994
DSM IVTR 2000
APPROACHES IN THE CLASSIFICATION
1. Classical or categorical approach
- assume every diagnosis has a clear underlying
pathophysiology (cause) and each disorder is unique.
So, diagnosis is possible if we know the cause of a
disorder.
- Emil Karpelin (1856-1926) Classified based on this
approach.
Problem: based on the biological tradition hence is
possible in case of medicine. Example: In Downs
syndrome – 21st extra chromosome
2. Dimensional approach
- variety of cognitions, moods, behavior which the
patient presents quantified in a scale.
Example: on a scale of 1 to 10 patient might be
rated as severely anxious (10), moderately
depressed (5) etc. This approach is applied in
diagnosis.
Problem - most theories do not agree on how
many dimensions are required- one or many?
3. Prototypical approach
• alternative approach in the classification of behavioral disorders
• gaining increasing support in recent years by experts all over the world.
• basically combines some of the essential features of
first two approach.
• makes use of some non-essential features of clinical conditions in the classification. Example: DSM classification
Need for the classification1. Classification is the heart of any scientific discipline.
2. For the better understanding of the abnormal behavior
3. To reduce the confusion and overlapping of symptoms
4. To communicate with the similar or other related professionals
5. To deal with any medico-legal issues
6. To avail any facilities or provisions made by law
and govt.
7. Helps to decide and select the appropriate
treatment procedures
8. Needs for research and documentation
DIAGNOSTIC AND STATISTICAL MANUAL OF DISORDERS (DSM )
• This system was evolved and prevailing in USA,
• developed by American Psychiatric Association.
• It first started in the year of 1952 and
subsequently underwent 5 revisions.
• Now we are using DSM IV-TR.
Certain features of DSM IV-TR are-
1.Multi axial classification, I, II, III, IV & V axis
2.Provisions for the gradation of severity of
clinical conditions
3.Provisions for frequently used criteria and
associated features
The five axis are-
Axis I –All Mental Disorders
Axis II –Personality disorder and mental retardation
Axis III -Any physical disorders or general medical
conditions
Axis IV– Psychosocial and environmental problems
Axis V - Global assessment of functioning (overall
level of functioning) *
* makes use of GAF Scale (Global assessment of
functioning Scale)
International Statistical Classification of Disease and Related Health Problems (ICD)
• Aim of ICD-
a. Standardized multi axial formulation
b. Idiographic formulation (clinicians/familial & combined perspective)
• This system was developed by W.H.O. (World Health Organization).
• Origin Can be traced back to Swedish biologist Carolus Linnaece’s taxonomic work in 18th Century.
• First international classification was done in the year 1893.
• Since then approximately for every 10 years it was
required to be revised.
• Since its foundation, the WHO ( 1948 ), assumed the
responsibility of preparation of this system.
• The 6th revision taken place in 1948.
• In the 10th revision which was revised in the year
1992, there are three axis
• Axis I – Clinical Diagnosis (Accommodates both
mental and non-mental disorders)
• Axis II - Disablement – Based on WHO Disability
Assessment Scale (DAS)
• Axis III- Contextual factors – Portray the context of
illness
Details of AXIS – II & III
AXIS – II (WHO Disability Assessment Scale)
• Personal care
• Occupational functioning
• Functioning with family
• Broad social behavior
Axis –III Contextual factors (6 areas)
1. Problems in the family
2. Problems in the social environment
3. Problems in the education
4. Problems in the employment
5. Problems in the housing
6. Problems in the social environment
7. Problems in the Economic area
