PSYB32H3 Lecture Notes - Lecture 3: Rorschach Test, Thematic Apperception Test, Criterion Validity
Document Summary
Reliability*: test-retest reliability, alternate-form reliability, internal consistency reliability. Validity*: content validity, criterion validity, construct validity. Having tests to be reliability and validity is important. Self-stigma/cultural factors can influence, which is a con by not doing test. Difficulty of convay for patients, influence can also play an important. Reliability: inter-related reliability = 2 people have same conclusion; test-retest reliability = ensure constancy, if its trandsent it won"t be constant, iq testing is test-retest reliability; Alternate-form reliability = 2 of the same type of test, the practice affect; internal consistency reliability= ruler example (10/10 inch) needs to have same amount of units. Validity: depended on reliability; weather it fulfill intended purpose; content = measure adequately samples the domain of interest; criterion = evaluating if 1. Concurrent validity = cognitive biases a person will also have depression (2 of the same things) 2. Predictive validity: ecological validity; construct = multiple means of evidence.
