In order to explore the proposed relationship between nightmare occurrence and schizotypy, 30 frequent-nightmare subjects (at least one occurrence per week) and 30 low-nightmare controls, all of whom were female college students, were compared on several converging measures of schizotypal signs and behaviors. Consistent with previous research, frequent nightmare subjects demonstrated greater deviance on psychometric scales of schizotypy, and reported significantly greater schizotypal symptomatology on a structured clinical interview, than controls did. In addition, nightmare subjects produced similar electrodermal habituation patterns to auditory orienting stimuli as those that have been documented in schizophrenia-spectrum disorders. The results suggest that nightmare experience may be a useful conjoint behavioral indicator for the early detection of schizophrenia-spectrum psychopathology.
为了探究所提出的噩梦发生与精神分裂症样人格特质之间的关系，对30名频繁做噩梦的受试者（每周至少做一次噩梦）和30名低噩梦发生率的对照组进行了比较，所有受试者均为女大学生，比较内容涉及精神分裂症样体征和行为的多项趋同测量指标。与先前的研究一致，频繁做噩梦的受试者在精神分裂症样人格特质的心理测量量表上表现出更大的偏差，并且在结构化临床访谈中报告的精神分裂症样症状明显多于对照组。此外，做噩梦的受试者对听觉定向刺激产生的皮肤电习惯化模式与精神分裂症谱系障碍中记录的模式相似。结果表明，噩梦经历可能是早期发现精神分裂症谱系精神病理学的一个有用的联合行为指标。
