Midterm Flashcards
What are the 3 steps to process?
- Evaluation
- Intervention
- Targeting of outcomes
Evaluation Process
- Screening (client/referral information)
- Occupational Profile
- Assessments used and results (objective)
- Analysis of occupational performance
Intervention Process
- Plan
- Implement (treatment)
- Review (re-evaluation)
OTA/OTR Relationship
- OTR can do the screening, evaluation (includes occupational profile, analysis of occupational performance, assessment), intervention, and targeting of outcomes
- OTA delivers services under the supervision and partnership of the OTR. Cannot do screening or evaluation, can perform some assessments that may contribute
Approaches for Intervention Implementation
- Create: Promote
- Establish: Restore
- Maintain: Preserve current skills
- Modify: Compensation, Adaptation
- Prevent: Disability Prevention
Psychometrics Terminology
What are 4 types of evaluator biases?
- Background
- Severity or Leniency
- Central Tendency
- Halo Effect
Background (evaluator biases)
values/beliefs
Severity or Leniency (evaluator biases)
Rates extremely high or low
Central Tendency (evaluator bias)
Choosing middle score bc can’t make a decision
Halo Effect (evaluator bias)
Prior experiences influence your current situation
-ex. Everything about your grandma makes you smile; you have a client who resembles her; you give the client the benefit of the doubt with everything
Evaluator Biases
Background severity or leniency, central tendency, and halo effect (bias on someone you might have known in past or previous experience)
Hawthorne effect
Happens to person who test is given to/ when person changes behavior and performance bc they are being watched can be good or bad
Observer expectation
If we want them to do better we grade more leniently or give more chances/ invested in development and influences how we rate them
Test biases
Gender education level, SES, ethnicity and culture, geographic location, medical status/ some tests are appropriate for certain patients (kids vs adults testing)
Scoring errors
Generosity, ambiguity (could go in different directions not sure what it means) halo, central tendency, leniency, severity, proximity (how an event influences performance)
Logical error and Contrast error
Insufficient info to decide on answer/too much divergence totally different scores
Errors of Measurement
- Item Bias
- Rater Error
- Individual Error
- Standard Error of Measurement
Item bias (errors of measurement)
Some may be easy some may be harder depending on person (language items)
Rater Error (errors of measurement)
Errors in judgment that occur in a systematic manner when an individual observes and evaluates another.
Individual error (errors of measurement)
Inability to perform test
Standard Error of Measurement (errors of measurement)
Best prediction of how much error still exists (can’t eliminate all error)
Reliability
Accuracy and stability or consistency of measure
- Intrarater
- Interrater
- Test-Retest
- Reliability Coefficient
- Internal Consistency/Homogenity
Intrarater (Reliability)
Ability to perform same assessment on same client twice and no change same results
Interrater (reliability)
When you and another therapist gets same results
Test-Retest (reliability)
At one point measure client as therapist and another time still accurate no
Reliability Coefficient
(+.80=good)
0-1 scale
