Chapter 3: Clinical Assessment and Diagnosis Flashcards
Purpose of Clinical Assessment
Treatment Planning, Understanding the individual, Predicting behavior, Diagnosing
Reliability
degree of consistency of a measurement
Inter-rater Reliability
measures the level of agreement between ratings by multiple people (raters, judges, etc.); higher = more accurate
Test-retest Reliability
a test produces similar results over time
Inter-item Reliability
consistency between multiple items measuring the same construct (multiple items tell you a result; ex: personality quizzes)
Parallel Forms Reliability
create more than one form that asses the same thing (ex: two different forms for an exam)
Validity
Does the test measure what it’s supposed to?
Face Validity
the assessment appears effected in terms of its stated aims
Content Validity
all factors have equal coverage
Criterion-related Validity
how well the measurement of one variable can predict the response of another variable
What are the two types of Criterion-related validity?
concurrent & predictive
Concurrent Validity
measures two variables at the same time to see if one is significantly associated with the other
Predictive Validity
determines if a measurement of one variable is able to accurately predict the measurement of some variable in the future
Construct-related Validity
how well a test measures the theory it is supposed to measure
Convergent Validity
Does it relate to things that it should relate to?
Discriminant Validity
Does it not relate to the things that it should not relate to?
Standardization
set of norms to ensure consistency throughout measurements
Clinical Interview
makes use of verbal communication; medical expert attempts to understand the patient’s mind through various questions and observing the reactions
Mental status exam
systematic observation; tests an individual’s cognitive function
Structured Clinical Interview
less open-ended and offer a guided approach
Semi-structured Clinical Interview
more open-ended
Unstructured Clinical Interview
completely directed by the clinician who chooses what questions are asked
Name the type of reliability: You go to a clinician on Tuesday and are told you have an IQ of 110, you should expect a similar result if you take the same test again on Thursday.
test-retest
Name the type of validity: The results from a standard, but long, IQ test were essentially the same as the results from a new, brief version.
Concurrent validity
