Ch. 3: The Process of OT Flashcards
OT Screening
- outcome of a screening will determine the client factors, areas of occupation, performance skills, patterns and/or contexts that require further eval.
- goals CANNOT be established or tx implemented/managed until AFTER an eval is complete
Standardization
- standardized evals are uniform and well established
- always the SAME in content, administration and scoring
Characteristics of a Standardized Assessment
- description of its purpose
- administration and scoring protocol
- established norms and validity
Norms
-used for comparative analysis of an individual’s score
Types of Norms
- age
- gender
- diagnostic criteria
Validity
-measures the assessments ACCURACY to determine if the tool measures what it is intended to measure
Face Validity
- how well the assessment instrument APPEARS OR LOOKS “on the face of it” to meet its stated purpose
- i.e. activity configuration looks like it measures time use
Content Validity
- content in the eval is representative of the content that could be measured
- i.e. does the content of a role checklist provide an adequate listing of roles
Criterion Validity
- COMPARES the assessment tool to another one that already has ESTABLISHED VALIDITY
- criterion validity is based on CORRELATION. HIGHER the correlation the BETTER the criterion validity
Concurrent Validity
-COMPARES the RESULTS of 2 instruments given at about the SAME TIME
Predictive Validity
-COMPARES the degree to which an instrument can PREDICT performance on a FUTURE criterion
Reliability
- establishes the CONSISTENCY and STABILITY of the eval
- if it is reliable, eval measurements/scores are the SAME from time to time, place to place, and eval to eval
IntErrater Reliability
-DIFFERENT people using the SAME ASSESSMENT will get the SAME results
Test-retest Reliability
-same results will be obtained when the eval is given TWICE by the SAME PERSON
Norm-referenced Assessments
-produce scores that compare a person’s performance to a SET POPULATION’S performance
