title: Further validation of a questionnaire method for classifying depressive illness.
abstract: A total of 367 patients admitted to a psychiatric facility completed the LPD questionnaire. By application a decision rule to their responses, they were classified as 'non-endogenous depression', 'endogenous depression' and 'non-depressive syndrome'. This classification was found to be associated significantly with their categorization on the basis of clinical diagnosis. The findings suggest that this method of classification on the basis of responses to the LPD may have a useful research and clinical role.
