A 5- to 8-year follow-up of first admissions to a local psychiatric service enabled the comparison of patients with and without symptoms for the presence of current problem areas. Whereas first admission was associated with a temporary high level of reports of problems, the 6-month and 5- to 8-year levels were stable. Relative risk of onset following an event compared with spontaneous onset was likewise stable for the different diagnoses, significant only for depressive states and not for schizophrenia or neurosis, despite higher overall reporting of problems in the latter. The type of depression emerging after problems was similar to that occurring spontaneously.
对当地精神科首次收治患者进行5至8年的随访，以便比较有症状和无症状患者当前问题领域的存在情况。首次收治与问题报告的临时高水平相关，而6个月及5至8年的水平则较为稳定。与自然发病相比，事件后发病的相对风险在不同诊断中同样稳定，仅在抑郁状态时显著，在精神分裂症或神经症中则不显著，尽管后者的问题总体报告率更高。问题出现后出现的抑郁症类型与自然发生的抑郁症类型相似。
