Psychological assessment: a systematic gathering and evaluation of information pertaining to an individual with suspected abnormal behavior. Series of scores placed within the context of the history, referral info, behavioural observations, and life of an individual. Test is only a sample of behavior (like a blood test) Diagnosis is only as good as the assessment which is only as good as the tools used. Accurate ability to measure some aspect of person. Knowledge of how people in general fare on such a measure (standard of comparison) Test-retest reliability: degree to which a test yields the same results when given more than once to the same personhigh correlation = good reliability. Problem: may improve due to knowledge carried over in second test. Alternate-form reliability: prepare two forms of the same testhigh correlation = high a-f reliability. Internal consistency: degree of reliability within a test. Split-half reliability: comparing responses on odd number with even number.
