Solving a puzzle: test-retest reliability, inter-rater reliability. Clinical assessment: systematic evaluation and measurement of psychological, biological and social factors in an individual presenting with a possible psychological disorder. Diagnosis: process of determining whether the particular problem afflicting the individual meets all the criteria for a psychological disorder. The referral question or purpose of the psychological assessment. One test= one piece of the puzzle. Reliability: yields the same results repeatedly under the same circumstances: degree to which the measurement is consistent, ex/ 4 different doctors giving you 4 different diagnoses and treatments. If you took the test again, you should get the same results. 2 of more raters will get the same results. Variability: performs the function it was designed to perform: concurrent or descriptive validity similar. Comparing the results of one assessment with the results of others: predictive validity future. How well your assessment tells you what will happen in the future.
