The Minnesota Multiphasic Personality Inventory (MMPI) profiles of 100 insomniacs who presented for treatment at a university medical center were analyzed by a hierarchical clustering procedure. This analysis revealed two major personality types that accounted for 88% of the sample. The two types referred to as "Type 1" and "Type 2" insomniacs differed significantly in regard to sleep history questionnaire responses and responsivity to treatment. MMPI scales and sleep history questionnaire items suggested that Type 1 insomniacs were less defended, more aroused/activated, and had sleep histories characterized by more childhood sleep problems and greater difficulties with sleep-disruptive cognitions than did Type 2 patients. Further, Type 1 patients had a poorer response to behavioral treatment as measured by change in sleep-onset latency than did Type 2 patients. These results suggest that the MMPI may be useful in identifying distinctive personality subgroups among insomniacs. Treatment implications are discussed, and mechanisms underlying the group differences are considered.
通过层次聚类程序分析了在一所大学医学中心接受治疗的100名失眠症患者的明尼苏达多相人格问卷（MMPI）剖面图。该分析揭示了两种主要的人格类型，占样本的88%。这两种类型被称为“1型”和“2型”失眠症患者，在睡眠史问卷回答和对治疗的反应性方面有显著差异。MMPI量表和睡眠史问卷项目表明，与2型患者相比，1型失眠症患者防御性较低，唤醒/激活程度较高，其睡眠史的特点是童年睡眠问题更多，睡眠干扰认知方面的困难更大。此外，通过入睡潜伏期的变化来衡量，1型患者对行为治疗的反应比2型患者更差。这些结果表明，MMPI可能有助于识别失眠症患者中不同的人格亚组。讨论了治疗意义，并考虑了组间差异的潜在机制。
