Computerized Assessment and the Future of Testing
Computers in Testing
- Computer-Assisted Psychological Assessment (CAPA)
oDesign Individualized tests
oInterpret test results
oWrite Reports
oPresent Test Stimuli
Computer-Based Test Interpretation: Current Status
- Scoring reports
oPresent scores, profiles, and confidence intervals
- Descriptive reports
oProvide a brief desc. Of each scale
- Examples: WAIS-IV (Fixed Battery -> discrepancies are
obvious), Personality Assessment Inventory (PAI), and
Conners Continuous Performance Test – II
o*Flexible -> not always the same test administered
Clinical vs. Actuarial Prediction
-Clinical Prediction uses examiner’s own judgment to
diagnose, classify or predict behaviour
-Actuarial prediction uses an empirically derived formula to
diagnose, classify or predict behavior
oFacilitated by (but not synonymous with) computerized
testing
“Even though outlier studies can be found, we identified
no systematic exceptions to the general superiority (or at
least material equivalence) or mechanical [actuarial]
prediction. It holds in general medicine, in mental health,
in personality, and in education and training settings. It
holds for medically trained judges and for psychologists.
It holds for inexperienced and seasoned judges”
