Interview & observation Anselm Fuermaier
Introduction
- Cognitive functions (cognition) functioning in daily life (behavior)
- Cognitive impairment impairment in daily life
o Pijl ertussen assessment
Psychometric npsy tests – performance tests
Clinical interviews (unstructured, semistructured, structured) – usually first
step
Questionnaires (self-report, other reports) – score them and quantify
behavior
Observations (during clinical assessment) – all aspects of clinical evaluation
Questionnaires and tests on memory not the same problems in quest.
And test but almost had no association to eachother (both sensitive)
Believe a test is optimal performance quest. More typical
performance
The clinical interview
- Before the interview record viewing (optimal situation)
o Injury and post-injury records
Head injuries
Cardiovascular accidents
Tumors/surgeries
Epilepsy
Infections
Neurodegenerative disorders
Alcohol abuse etc.
o Neuroimaging data – location brain damage
o Psychiatric history
Developmental disorders (‘premorbid’ reference point lacking)
Very important what can you expect to be normal, premorbid level
of functioning, baseline level, affects self-report of patient (learn to
compensate, what is really the impairment)
Psychotic disorders (decreased insight?)
Self-report may be biased
Affective disorders (often associated with marked cognitive impairments)
Lijken op elkaar
Anxiety disorders
Personality disorders (treatment motivation?)
Suicide attempts
o Previous (npsy) assessments – parallel tests, learning effect etc.
o Previous treatments behavioral and pharmacological interventions
Pharmacological very useful to know what helped before, hoe het nu gaat
tegenover voor medicatie
Mood stable but cognitive problem unaffected etc.
o School records
Grades
Standardized test scores
Transcripts
Reports
o Vocational situation – what can you expect as baseline functioning
, Training
Type of job
Working hours
Reports
o Physical problems
o Where does the information stem from? – is information confirmed by multiple
(independent) sources?
Do not rely on one source, talk to family
- Before the interview are you prepared?
o What is the purpose of assessment?
o What is the aim, which question will be addressed?
o Are you confident your assessment will help to answer this question?
o Are you confident your level of expertise is sufficient to answer this question?
o Are you confident your equipment is sophisticated enough to answer this question?
- Performing the interview
o Informing the patient about purpose and content
The patient’s reports and behavior can only be interpreted in a valid fashion
if the patient has been informed about purpose, content, and duration of the
interview!
What is the goal of the interview explain etc.
o Biographical information
Family situation – parents, siblings
School situation
Vocational situation
Socio-economic status
Private situation – partnerships, stability of friendships, children
Living situation
Interests, hobbies and goals
Stressors – partnership crises, children, parents, job, money
o Premorbid level of functioning
Previous assessments
School education
Vocational situation
Income
Hobbies and interests
Family background
Acquired brain damage vs. developmental disorder
Involve a spouse/parent! (if patient agrees)
Not necessarily more valid or reliable give a different view, but
very important
Discrepancy between self- and informant report
Evaluation of insight of patient
Many standardized scales offer self- and other report forms –
quantify between self-report and other reports
o Type and nature of complaints
Start with spontaneous self-reported complaints – don’t direct, stay on
general level
Rather on behavioral level, than on a level of cognitive functions
Ask to specify complaints and to give examples
Check the patient’s interpretation!
Example
, o Different meaning of attention (cognition vs. self-
presentation)
o Many causes for loss of interest in reading (motivational,
cognitive, visual, …)
Continue with more specific questions
When did they start? How?
How often do they occur?
In which intensity?
Information and further elaboration on medical history helps and
guides your interview on complaints!
o Did medication help? In which way?
o Did other form of treatment help?
o Discrepancy between medical records and self-reports
informative! – what you took and how it helped
Eventually determine complaints on cognitive/modular level
Attention and concentration
Memory and orientation
Planning, flexibility and reasoning
Impulse control
Language and arhythmics
Perception
Motor behavior and praxis
Personality characteristics
Physical complaints
o Course of complaints – very important, are problems because of stroke, depression or
first symptom of MCI, remission?
Are complaints getting worse? Since then? How?
Period of remission?
What became worse, what became better?
o Consequence of complaints
Do complaints affect daily functioning? How? – no problems in life,
psychiatric disorder not necessary. In environment where his symptoms do
not affect him
Observations
- Think beforehand about the behavior you like to observe
- In which situations
o During administrative contact prior and after assessment - how they make
appointments
o Waiting room – punctual, inpatient, problem in questionnaires, how they wait
o On the way to the testing room
o During the interview
o During testing
- What can we learn?
o Level of arousal and alertness – concentration
o Retrieval of recent and remote events – memory
How coherent their past is
o Thought content and processes – executive functions
o Emotionality – e.g. affect, mood, and appropriateness)
o Level of cooperation – effort and motivation
, o Appearance – manner of dress, gait, posture
o Sensorimotor functions – e.g. muscle strength, eyesight, hearing
o Discourse abilities – conversational speech
o Appropriateness of social skills
- What kind of behavior?
o Appearance
Noticeable, physical characteristics (overweight, health, etc.)
Personal care (proper, untidy)
More/less youthful than indicated by age
o Motor skills
Overall
E.g. speed of movements, hyperactivity, restlessness, fidgeting,
clumsiness, sudden or careless movements, neglecting one side of
body, (partial) paresis, involuntary muscle spasms, tremor, difficulty
controlling movements
Walking
E.g. speed, flexibility, rigidity, tripping, bumping into things (on the

Suspicious, criticizing, shows aggression or annoyance
Disinhibited, comments on all actions, responds to contact straightforwardly
- At specific actions

Writing/reading
Planning meetings and making agreements (e.g. questionnaires, medication)
Instruction phase and practice trials of npsy tests
Reactions to feedback in npsy tests
Describing complex drawing
Drawing complex figures (copying, or clock drawing)
Strategy of planning tasks
Interview and observation
- Validity (accuracy of conclusions) and reliability (consistency between clinicians)
o Validity and reliability vary greatly, but usually never above 0.8
o Reliability demands consistency – often not given due to large differences across
raters. Interaction between clinician and patient very specific
