积极和消极的人格缺陷在社会关系、情感和日常生活中的功能方面表现出不同的损害模式。然而，研究还没有检查过精神病样，偏执和阴性症状的现实世界表达的拟真型的关联。本研究采用经验抽样方法（ESM），以评估在日常生活中的206名西班牙年轻人的非临床样本的积极和消极的automotypy。参与者每天被随机提示8次，持续1周，以完成对他们当前症状和经历的评估。阳性拟形与日常生活中的精神病样症状和偏执症状有关。阴性异型性与这些症状的子集和日常生活中的阴性症状相关。短暂的压力与精神病样和偏执症状有关，但仅适用于那些高阳性的精神分裂症。社会压力预测的瞬间精神病样症状的积极和消极的autootypy。时间滞后分析表明，在先前的信号预测精神病样症状的压力在当前的评估，但只有个人在积极的精神病样。结果与将压力敏感性与精神病症状的经历联系起来的模型一致。这些发现为分裂型和精神分裂症的多维模型提供了跨文化支持。此外，研究结果表明，ESM是预测日常生活中精神病样症状及其前兆的有效方法。
Positive and negative schizotypy exhibit differential patterns of impairment in social relations, affect, and functioning in daily life. However, studies have not examined the association of schizotypy with real-world expression of psychotic-like, paranoid, and negative symptoms. The present study employed experience-sampling methodology (ESM) to assess positive and negative schizotypy in daily life in a nonclinical sample of 206 Spanish young adults. Participants were prompted randomly 8 times daily for 1 week to complete assessments of their current symptoms and experiences. Positive schizotypy was associated with psychotic-like and paranoid symptoms in daily life. Negative schizotypy was associated with a subset of these symptoms and with negative symptoms in daily life. Momentary stress was associated with psychotic-like and paranoid symptoms, but only for those high in positive schizotypy. Social stress predicted momentary psychotic-like symptoms in both positive and negative schizotypy. Time-lagged analyses indicated that stress at the preceding signal predicted psychotic-like symptoms at the current assessment, but only for individuals high in positive schizotypy. The results are consistent with models linking stress sensitivity with the experience of psychotic symptoms. The findings provide cross-cultural support for the multidimensional model of schizotypy and schizophrenia. Furthermore, the findings demonstrate that ESM is an effective method for predicting the experience of psychotic-like symptoms, as well as their precursors, in daily life.
