Foundations of Assessment/The Assessment Process Flashcards
the systematic process of gathering information about an individual to make decisions regarding their treatment plan
Assessment
process of collecting, analyzing, and reporting
Systematic
once all info is gathered you must ANALYZE + PRIORITIZE
Main point of activity
Why is assessment important to client?
- treatment placement decisions
- gain client info (baseline, progress, discharge)
- communication w/ client + caregivers
Why is assessment important to program?
- administrative requirements (reimbursement, regulations)
When is assessment used?
during interventions (assessment + documentation = intervention)
what are the 5 basic principles of assessment
-systematic process
-logical connection
-yielding dependable and consistent results
-placement
-provide baseline info.
Current problems w assessment
- research into functional meaning of assessment scores
- modification of valid instruments
- research using RT instruments w coefficient BELOW 0.80 (reliability)
- reducing the number of agencies using homemade assessments and/or leisure-only surveys
CONSISTENCY
- refers to the scores or data and NOT the instrument
- high reliability does not assure validity!
reliability
a method for determining the reliability of a test by comparing a test taker’s scores on the same test taken on separate occasions
test-retest reliability
Split-half reliability is a method used to assess the internal consistency of a test or assessment. It involves dividing the test into two equal halves (usually odd and even items) and then comparing the results from each half to see if they produce similar scores.
- ensure that an assessment tool consistently measures what it is intended to, regardless of how the questions are split. This helps in confirming that the tool is reliable and that the results are not dependent on the specific selection of items.
split-middle reliability
types of reliability
- stability
- equivalence
- internal consistency
- objectivity
a measure of how consistent a test is over time
- measures not accurate for knowledge or paper-pencil tests
- better indicator for physical fitness (HR and BP) or motor performance
- time administrations should be timed appropriately
stability (reliability)
The extent to which measurement on two or more forms of a test is consistent
- used for knowledge tests to determine reliability indices for standardized tests e.g., ACT or SAT)
- parallel or alternate forms method (e.g., English vs Spanish version)
equivalence (reliability)
a way to determine if multiple items on a test that are intended to measure the same thing produce similar scores.
- A quiz that measures students’ ability to solve quadratic equations should have internal consistency. If a student answers one item correctly, they should also be able to answer similar items correctly
internal consistency (reliability)
