This study examined narrative identity in a group of 81 patients with schizophrenia and 50 healthy controls through the recall of self-defining memories. The results indicated that patients' narratives were less coherent and elaborate than those of controls. Schizophrenia patients were severely impaired in the ability to make connections with the self and extract meaning from their memories, which significantly correlated with illness duration. In agreement with earlier research, patients exhibited an early reminiscence bump. Moreover, the period of the reminiscence bump, which is highly relevant for identity development, was characterized by fewer achievements and more life-threatening event experiences, compared with controls. A negative correlation was found between negative symptoms, number of self-event connections and specificity of narratives. Our results suggest that schizophrenia patients have difficulties to organize and extract meaning from their past experiences in order to create coherent personal narratives.
本研究通过回忆自我定义的记忆，考察了 81 名精神分裂症患者和 50 名健康对照者的叙述身份。结果表明，与对照组相比，患者的叙述缺乏连贯性和详细性。精神分裂症患者在与自我建立联系和从记忆中提取意义的能力上严重受损，这与疾病持续时间显著相关。与早期研究一致，患者表现出早期怀旧高峰。此外，与对照组相比，怀旧高峰期间（与身份发展高度相关）的成就较少，危及生命的事件经历较多。负面症状、自我事件联系数量和叙述的特异性之间存在负相关。我们的研究结果表明，精神分裂症患者在组织和提取过去经历中的意义以创建连贯的个人叙述方面存在困难。
