Document Summary
Psychological assessment refers to the systematic gathering and evaluation of information pertaining to an individual for whom a specific question about psychological functioning needs answering. Assessment requires the clinician to place and interpret scores and other data within the context of the person"s history, referral information, behavioral observations and life story of that person in order to provide a comprehensive understanding of that individual. Content validity is one step beyond face validity in requiring that the test"s content include a representative sample of behaviours thought to be related to the construct the test is designed to measure. Criterion validity is said to have been achieved when the test results match what is known in the population (i. e. , a depression test has criterion validity if it discriminates between depressed and non- depressed people) Construct validity is concerned with the importance of a test within a specific theoretical framework; especially useful for abstract constructs.
