Patients with Primary insomnia often experience intrusive, worrisome cognitive activity in the pre-sleep period. Metacognitive beliefs may explain this yet no valid reliable scale exists. The present study, therefore, developed the Metacognitions Questionnaire--Insomnia (MCQ-I). Following initial metacognitive insomnia profiling interviews, item refinement produced a preliminary 60-item MCQ-I. This was administered to 34 primary insomniacs and 37 normal sleepers. Psychometric data indicate primary insomniac patients score significantly higher than normal sleepers on MCQ-I. Test-retest reliability is good. Face, concurrent, construct and discriminant validity, scale sensitivity and specificity are all acceptable. Further research with larger primary insomnia and normal sleeper samples is now required.
原发性失眠患者在睡前往往会经历侵入性、令人担忧的认知活动。元认知信念或许可以解释这一现象，但目前尚无有效的可靠量表。因此，本研究开发了元认知问卷——失眠版（MCQ-I）。在进行初步的元认知失眠剖析访谈后，通过项目优化得出了一个包含60个条目的初步MCQ-I。该问卷施测于34名原发性失眠患者和37名正常睡眠者。心理测量数据表明，原发性失眠患者在MCQ-I上的得分显著高于正常睡眠者。重测信度良好。表面效度、同时效度、结构效度、区分效度、量表敏感性和特异性均为可接受。现在需要对更大样本的原发性失眠患者和正常睡眠者进行进一步研究。
