Diagnostic Reliability of the DSM-5

After reading the Regier et al. (2013) article and page 110 in your text, in your own words, define both diagnostic reliability and intraclass kappa. Then, from the 15 diagnoses that were investigated, choose one diagnosis that was found to be in the “very good” range of reliability detailing what that signifies statistically. In addition, offer both a hypothesis as to why it has such good reliability and what might be a clinical benefit to having very good reliability. Lastly, identify one diagnosis that scored in either the questionable or unacceptable range of reliability and answer the same questions.
