ch 2: neuropsychological assessment Flashcards
(50 cards)
What are the primary purposes of clinical assessment?
To conduct a differential diagnosis, describe behavior, predict risks and outcomes, monitor treatment responses, and guide interventions.
What is differential diagnosis in clinical assessment?
Determining whether symptoms are due to different possible causes, such as a dementing process issue vs. substance use issue.
Why is describing behavior important in clinical assessment?
To understand the effects of specific conditions (e.g., head injury) on executive, language, or motor functions.
How does clinical assessment help predict risks and outcomes?
It assesses whether an individual can return to work or resume previous activities.
How does clinical assessment monitor treatment responses?
By evaluating the effectiveness of treatment and determining whether modifications are needed.
What is neuropsychological testing?
An objective, comprehensive assessment of cognitive and behavioral functioning.
What types of information should be gathered about the patient?
Medical, social, academic, and other contextual information.
What are the key concepts in assessment?
Reliability, validity, and standardization.
What is reliability?
Consistency in measurement (e.g., test-retest, split-half, internal consistency).
What is validity?
Measuring what the test is intended to measure (e.g., face validity, ecological validity, criterion-oriented validity).
What is standardization?
Consistent use of a technique or device, ensuring questions are asked the same way for all individuals.
What is test-retest reliability?
Comparing scores of a test taken at two different times.
What is split-half reliability?
Administering one test, splitting it into two parts, and correlating the scores to avoid practice effects.
What is inter-rater reliability?
Ensuring consistency when multiple individuals rate or judge a phenomenon using the same rubric.
What is face validity?
The test appears to measure what it is supposed to measure (e.g., asking about recent depression).
What is ecological validity?
The extent to which test results mimic real-world functioning.
What is criterion-oriented validity?
How well scores differentiate between people with and without a specific condition (e.g., concurrent or predictive validity).
concurrent validity
currently possess the ability to do the task that is asked; e.g., blood test comes back positive for a disease
predictive validity
- score will determine that you will have it
- Does the test correlate with future abilities/behavior?
What is construct validity?
Whether the test measures the concept it claims to measure.
How is construct validity established?
Through convergent validity (correlation with gold standard tests) and discriminant validity (no correlation with unrelated constructs).
What are the outcomes in signal detection for diagnosis
hit, false positive, false negative, correct rejection
hit
disease present, test positive
false alarm (type 1 error)
disease absent, test positive
