背景：精神病患者会经历个人身份的破坏，从而影响阳性和阴性症状，但这些现象的复杂性需要深入解决。使用个人建构理论，我们检查了个人身份的不同维度（用保留网格技术以及其他认知因素测量）是否可能影响精神病症状。方法：85 名患有精神分裂症谱系障碍的门诊患者完成了一份清单表、对精神病症状的观察评级访谈以及认知洞察力、抑郁症状、神经认知和心理理论的测量。结果：结构方程模型显示，人际二分思维直接影响阳性症状。自我差异通过调节抑郁症状影响积极症状。人际认知分化和人际认知丰富性介导了阴性症状中自我反思和神经认知缺陷的影响。结论：这项研究是同类研究中第一个研究个人身份结构与精神病的阳性和阴性症状之间关系的研究。结果表明，旨在改善人际二分思维、自我差异、人际认知分化和人际认知丰富性的干预措施可能有助于改善精神病症状。
Background: People with psychosis experience disruptions in personal identity that affect positive and negative symptoms, but the complexity of these phenomena needs to be addressed in an in-depth manner. Using the Personal Construct Theory, we examined whether distinct dimensions of personal identity, as measured with the Repertory Grid Technique along with other cognitive factors, might influence psychotic symptomatology. Method: Eighty-five outpatients with schizophrenia-spectrum disorders completed a repertory grid, an observed-rated interview of psychotic symptoms, and measures of cognitive insight, depressive symptoms, neurocognition, and theory of mind. Results: Structural equation models revealed that interpersonal dichotomous thinking directly affected positive symptoms. Self-discrepancies influenced positive symptoms by mediation of depressive symptoms. Interpersonal cognitive differentiation and interpersonal cognitive richness mediated the impact of self-reflectivity and neurocognitive deficits in negative symptomatology. Conclusions: This study is the first of its kind to examine the structure of personal identity in relation to positive and negative symptoms of psychosis. Results suggest interventions targeted to improving interpersonal dichotomous thinking, self-discrepancies, interpersonal cognitive differentiation, and interpersonal cognitive richness may be useful in improving psychotic symptoms.
