Evaluation of psychological, biological, and social factors in an individual. To establish a diagnosis (label for a set of symptoms that often occur together) Key concepts (psychometrics) that determine the value of clinical assessments are reliability, validity, standardization. Principles of tests construction: reliability (degree to which a measurement is consistent) Test-retest / temporal stability ~ test produces similar results when given at two points in time. Internal consistency ~ different parts of the same test produce similar results. Interrater / interjudge~ two or more judges who administer a test come to similar conclusions. Parallel / alternate forms~ two versions of the same test produce similar results. Principles of test construction: validity (degree to which a technique measures what is is designed to measure) Content validity~ test assesses all important aspects of a phenomenon.
