Appraisal/Assessment/Evaluation
|
Refers to the process that helps determine/estimate nature and intensity of different attributes, abilities, and behaviors of an individual
-Uses formal/standard and informal instruments |
|
Ethics
|
-Best interest of the client
-Informed Consent -Records -Competence -Test security |
|
Multicultural issues
|
-Note that not all tests have been standardized on other cultures, and there can be content bias in the test
-Also, know rights of handicapped individuals -lastly, mental disorders are defined in cultural context |
|
Reliability
|
A reliability coefficient of .75 to +1.0 is strong
Types: -Test-retest -Parallel/Alternative Forms -Split half -Internal Consistency Procedures -Inter-Rater Reliability |
|
-Test-retest
|
Same subjects are given a test twice, with some space in between
- exposure can be a problem |
|
-Parallel/Alternative Forms
|
Two similar tests are given to the same people at different times, thus item consistency can be assessed
-consistency between tests is not always as good as hoped for |
|
Split-half Procedures
|
Examiner creates parallel forms by splitting the one test in half and measuring consistency
-sometimes creates inflated estimates of reliability |
|
Internal Consistency
|
-Most popular reliability assessment
-Coefficient alpha/Chronbach's alpha -compares each score to the overall test score -Could use Kuder-Richardson |
|
Inter-Rater Reliability
|
The degree to which different rates arrive at similar judgements
-Each test scores by two or more judges |
|
Standard Error of Measurement (SEM)
|
Statistically checking reliability
-Tests with a small SEM have a high reliability coefficient and visa-versa -68% of the time an examinees true score falls withing +/- 1 of their obtained score - Add and subtract the SEM from the obtained score. Those numbers make up the range where the persons true score is |
|
Types of tests
|
Speed: Can't finish the test in the time (WAIS, WRAT)
Power: Some very difficult items which few people can answer. |
|
Factor affecting reliability
|
-Test length: greater (of similar items)= better
-Homogeneity: less variety = better -Test-retest interval:shorter=better -Range constriction: greater variance = better -Other systematic or unsystematic |
|
Validity
|
The degree to which the test measures what it is supposed to measure
-Calculated with validity coefficient (the square of the correlation between test scores and criterion score) -How much the change in one score can predict/explain the change in the other |
|
4 Types of Validity
|
Face
Content Criterion Related Construct |
|
Face
|
-No coefficient
-The degree to which the items on the test appear to be testing the right subject/construct |
|
Content
|
-Degree to which a sample of test items adequately represents/covers content area.
-Test should accurately and evenly sample the domains of interest |
|
Criterion Related
|
-The extent to which a test can predict, diagnose, or classify an individuals behavior in specific situations
Types: Predictive, Diagnostic (current state), Concurrent (test score against external crieterion) |
|
Construct
|
-The extent to which a tests measures a concept, construct, or trait of interest
-Takes years, can use a series of comparisons (convergent and divergent validity coefficients) |
|
Test construction Issues (item analysis)
|
-Item analysis evaluates test items:
-The item Difficulty Index -The Item Discrimination Index: |
|
The item Difficulty Index
|
describes percentage of persons who answer an item correctly (.50 is ideal)
|
|
The Item Discrimination Index
|
Descries the relative performance of the top and bottom quarter of the distribution of the sample on the item
-Tries to see if those who did good overall did good on certain items, and those who did poorly overall did poorly on certain items -does the item "discriminate" between those who scored highly and those who did not |
|
In court, what two things should a counselor expect to have to prove
|
Competency and training to use and interpret the instrument
The validity and reliability of the instrument itself |
|
Things to consider for tests
|
-Cost
-time limits -ease of administration -format -availability for alternate format -multiple-level exams -availability of answer sheets and simple scoring procedures -ease of interpretation |
|
Criterion Referenced Test
|
Compares performance with a predetermined set of criteria (believed to be essential)
|
|
Normative Referenced
|
Compares scores to those who took the test previously
|
|
Subjective Tests
|
The answer is formulated by the participant, and is thus harder to score, but can have more validity
|
|
Objective Tests
|
Subjects single out the answer from provided answers. Easier to score and stronger reliability
(MMPI, BDI) |
|
Individual Tests
|
-Advantages: rapport building, and understanding of client
-Disadvantages: More time consuming and expensive |
|
Group Tests
|
-Advantages: objective scoring, better norms, economical
-Disadvantages: no chance of individual rapport, can't understand external factors of people, dependent on reading skills of the examinee |
