Psychiatric Cases Classification based on GHQ of Silvapulle (1981)
Description
These data are from a psychiatric study of for 120 patients on the relation between the value of the score on the 12-item General Health Questionnaire (GHQ) and classification as a psychiatric case ("yes" or "no"). The patients attended as general practitioner's surgery and were administered the GHQ, resulting in a theoretical score between 0 and 12 (there were no cases or non-cases with GHQ scores of 11 or 12). Subsequently the patinets were given a full psychiatric examination by a psychiatrist who did not know the patient's GHQ score. The patient was classified by the psychiatrist as either a clinical case requiring psychiatric treatment (case="yes"), or as non-clinial (case="no"). The biological sex of the patients was also recorded.
