Assessment- Introduction Pt.2 Flashcards
In referring to accuracy in clinical predictions, psychologists employ two additional concepts: sensitivity and specificity. What is sensitivity?
Sensitivity refers to the number of times an event is predicted across cases compared with the total number of times the event actually occurs.
In referring to accuracy in clinical predictions, psychologists employ two additional concepts: sensitivity and specificity. What is specificity?
The opposite of sensitivity. Specificity deals with the prediction of non events compared with the total number of times the event didn’t occur.
What is treatment planning
A process where information about the clients context is used in combination with the scientific literature on psychotherapy to develop a proposed course of action. It gives the client realistic expectations about the process and likely outcome of treatment
A useful treatment plan must cover what 3 general areas
Problem identification, treatment goals, and treatment strategies and tactics
What is treatment monitoring
Tracking progress through the use of specific questions or psychological measures. It enables the psychologist to change the treatment plan based upon the patients response to treatment
What did Michael lambert demonstrate.
That “routine treatment monitoring” can effect treatment outcome. Using monitoring data to alert clinicians to treatment progress created better outcomes.
What is standardization
Consistency across clinicians and testing occasions in the procedure used to administer and score a test
What is Internal consistency
The extent to which all aspects of a test contribute in a similar way to the overall score ( consistency of a test )
What is inter-rater reliability / inter-scorer reliability
The extent to which similar results would obtained if the test was conducted by another evaluator
What is “evidence of content validity”
Ensuring that the test includes items that are representative of the psychological construct the test is designed to measure
What is “evidence of concurrent validity”
Scores/data on the test are correlated with scores of similar constructs.
What is evidence of predictive validity
The extent to which the test predicts a relevant outcome
What is evidence of discriminant validity
The test provides a pure measure of the construct that is not contaminated by other constructs
What is evidence of incremental validity
The extent to which a measure adds to the prediction of a criterion compared to other sources of data.
