Document Summary
Reliability: the degree of agreement between different clinicians who are using the system. The accuracy of the info that the diagnostic provides. Looking to see if the category clearly describes the disorder and differentiates it from another. Should allow clinician to classify it and see it as meaningfully distinct from other disorders. This validity asks whether the label will help the clinician to predict future symptoms, prognosis, etc. Ex. the common symptom of insomnia/excessive sleep is usually in major depressive disorder. Clinicians expect that the patient will develop sleep problems, even if they do not have them right now. You are able to predict symptoms based on what you know about the disorder. Needs to be based on research elements. Need the description of childhood problems to be different from adults. Predictive validity is high when using medications. With past versions of the dsm, there have not been as many diagnostic categories.
