132 psoriasis patients who had been completely cleared with dithranol were assessed and then followed up over a 3-year period. The incubation time from specific incidents of stress to the development of psoriasis was between 2 days and 1 month. Specific stress within a month before the first attack was recalled by 51 patients (39%); chance association was excluded by studying a control group where there was significantly less specific stress. The prognosis for the psoriasis patients who recollected specific stress a month prior to the onset was significantly better than for the rest of the patients where none had been recalled.
对132名已用蒽林完全清除银屑病的患者进行了评估，并在3年期间进行随访。从特定应激事件到银屑病发病的潜伏期为2天至1个月。51名患者（39%）回忆起首次发作前一个月内的特定应激；通过研究一个特定应激明显较少的对照组排除了偶然关联。回忆起发病前一个月特定应激的银屑病患者的预后明显好于其余未回忆起应激的患者。
