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.
共有367名入住精神病院的患者完成了LPD问卷。通过对他们的回答应用决策规则，将他们分为“非内源性抑郁症”、“内源性抑郁症”和“非抑郁综合征”。结果发现，这种分类与基于临床诊断的分类显著相关。研究结果表明，这种基于LPD回答的分类方法可能具有有用的研究和临床作用。
