This 18 month prospective study assessed the time course of sleep disturbances in 85 male psychiatric out-patients and 103 male non-patients. Over one-third of the patients and 5 per cent of the non-patients reported frequent symptoms of insomnia during at least 14 of the 18 months. Frequency and chronicity of insomnia were strongly associated with intensity of psychiatric symptomatology, but not with diagnosis. Minor tranquillizers and hypnotics were used frequently by patients and occasionally by non-patients, but there was little indication that they altered the course of insomnia.
这项为期18个月的前瞻性研究评估了85名男性精神科门诊患者和103名男性非患者的睡眠障碍时间进程。超过三分之一的患者和5%的非患者报告称，在18个月中的至少14个月里经常出现失眠症状。失眠的频率和持续性与精神症状的严重程度密切相关，但与诊断无关。患者经常使用小剂量镇静剂和催眠药，非患者偶尔使用，但几乎没有迹象表明这些药物改变了失眠的病程。
