Document Summary
Clinical assessment evaluation of the psychological, biological and social factors of the person presenting with a possible disorder. Diagnosis determining whether the problem meets dsm criteria as a disorder. Clinicians assess for disorders in a way that is analogous to a funnel. They collect a lot of information and narrows it down to one relevant area. The methods used for assessments are valuable based on their reliability, validity and standardization. Inter-rater reliability is high when different raters make the same conclusions. Test-retest reliability is high if test scores stay the same after multiple trys. Validity is how well it measured what it is supposed to measure. Concurrent (descriptive) validity is high if the results match other, more established measurements. Predictive validity is high is assessment correctly indicates what will happen in the future. Standardization specific norms set in order to make the test consistant across different measurements.
