The Present State Examination was administered to 539 patients who attended a casualty department after an act of self-poisoning during the course of a year. Computer analysis by means of the Catego program showed that 30% of the patients had insufficient symptoms to be considered as psychiatric 'cases'. Fewer than 4% had symptoms of functional psychosis. About 60% of the patients were classed as depressed: on several indices this group was less severely ill than a group of depressives feceiving psychiatric treatment. It is suggested that psychiatric treatment is essential for only a small proportion of self-poisoning patients. The effectiveness of psychiatric treatment for the large group of patients with depressive disorders of minor severity and probably short duration has still to be evaluated.
对一年中因自我中毒而到急诊部就诊的539名患者进行了现状检查。通过Catego程序进行的计算机分析表明，30%的患者症状不足，不能被视为精神科“病例”。不到4%的患者有功能性精神病症状。约60%的患者被归类为抑郁症患者：在几个指标上，该组患者的病情不如接受精神科治疗的抑郁症患者严重。有人认为，只有一小部分自我中毒患者需要精神科治疗。对于一大批病情较轻且可能病程较短的抑郁症患者，精神科治疗的效果仍有待评估。
