与非缺陷精神分裂症 (NDS) 患者相比,缺陷精神分裂症 (DS) 患者的洞察力明显较差. 这种差异与负面症状和认知障碍有关,这表明了干预的潜在目标.
科学领域:
- 精神病学是一个精神病学.
- 临床心理学 临床心理学
- 神经科学是一个神经科学.
背景情况:
- 缺陷精神分裂症 (DS) 与非缺陷精神分裂症 (NDS) 相比,与更低的洞察力有关.
- DS与洞察力缺陷之间的确切关系尚不清楚.
- 这项研究系统地审查和元分析了DS和NDS患者之间的洞察力差异.
研究的目的:
- 系统地审查和分析比较缺陷精神分裂症 (DS) 与非缺陷精神分裂症 (NDS) 的洞察水平的研究.
- 了解洞察力,负面症状和DS的认知功能之间的关联.
主要方法:
- 一个符合PRISMA的系统审查和PubMed,Scopus和Web of Science的研究的元分析.
- 包括使用任何验证的洞察力测量方法,检查DS和NDS之间的洞察力差异的研究.
- 结果数据的叙述综合和随机效应元分析 (SMD),评估偏差风险和证据确定性 (JBI,GRADE).
主要成果:
- 包括九项研究 (N=895; n=239 DS).
- 叙事综合表明,在DS中,洞察力缺陷更大,与表达性的负面症状和元认知障碍有关.
- 分析显示,DS与NDS的洞察力明显较差 (SMD=0.99,p=0.009),具有相当大的异质性 (I2=82.1%).
结论:
- 与NDS患者相比,缺陷精神分裂症患者的洞察力明显较差.
- 对DS的洞察力较差与持久的负面症状和认知功能障碍有关,特别是在自我反思方面.
- 针对这些认知和元认知缺陷的干预措施可以提高洞察力和患者的结果.
