目的:分裂型是检查病因的有用和统一的构建体,发展,和精神分裂症谱系精神病理学的表达。积极的,负,和杂乱无章的分裂型维度与精神分裂症谱系症状和损害的不同模式相关。此外,他们通过精神病样的平均水平来区分,可疑,负,以及日常生活中混乱的精神分裂经历,以及影响的时间动态。因此,假设分裂类型的维度可以通过日常生活中分裂类型经历的时间动态来区分。
方法:本研究在大量非临床确定样本(n=693)中采用经验抽样方法来检查多维分裂型与精神病样的关联,可疑,负,以及日常生活中混乱的精神分裂经历,以及它们的时间动态(可变性,反应性,惯性,和不稳定性)。
结果:我们复制了日常生活中多维分裂型和分裂型经历之间的平均水平关联。此外,积极的,负,杂乱无章的分裂型被证明是假设的,分裂型经验的时间动态的差分模式。杂乱无章的分裂型表现出最强烈的关联,包括强度,可变性,以及无序分裂经验的惯性。在先前报道的压力之后,杂乱无章的分裂型也减轻了精神病样和杂乱无章的分裂型经历的反应性。分裂型阳性与精神病样经历的强度和变异性有关。阴性分裂型与阴性分裂型经验的强度和变异性有关。
结论:研究结果表明,分裂型维度可以通过精神病样的平均水平和时间模式来区分,可疑,负,以及日常生活中混乱的精神分裂经历,具有以应激反应为独特特征的杂乱无章的分裂型。
OBJECTIVE: Schizotypy is a useful and unifying construct for examining the etiology, development, and expression of schizophrenia-spectrum psychopathology. The positive, negative, and disorganized schizotypy dimensions are associated with distinct patterns of schizophrenia-spectrum symptoms and impairment. Furthermore, they are differentiated by mean levels of psychotic-like, suspicious, negative, and disorganized schizotypic experiences in daily life, and by temporal dynamics of affect. The schizotypy dimensions were thus hypothesized to be differentiated by the temporal dynamics of schizotypic experiences in daily life.
METHODS: The present study employed experience sampling methodology in a large nonclinically ascertained sample (n = 693) to examine the associations of multidimensional schizotypy with psychotic-like, suspicious, negative, and disorganized schizotypic experiences in daily life, as well as with their temporal dynamics (variability, reactivity, inertia, and instability).
RESULTS: We replicated the mean-level associations between multidimensional schizotypy and schizotypic experiences in daily life. Furthermore, positive, negative, and disorganized schizotypy demonstrated hypothesized, differential patterns of temporal dynamics of schizotypic experiences. Disorganized schizotypy demonstrated the most robust associations, including intensity, variability, and inertia of disorganized schizotypic experiences. Disorganized schizotypy also moderated reactivity of psychotic-like and disorganized schizotypic experiences following previously reported stress. Positive schizotypy was associated with intensity and variability of psychotic-like experiences. Negative schizotypy was associated with intensity and variability of negative schizotypic experiences.
CONCLUSIONS: The findings indicate that schizotypy dimensions can be differentiated by both mean levels and temporal patterns of psychotic-like, suspicious, negative, and disorganized schizotypic experiences in daily life, with disorganized schizotypy uniquely characterized by stress reactivity.
