Improving diagnostic batteries to identify individuals at-risk for developing psychotic disorders as early as possible is an ongoing challenge in schizophrenia research. Here, we sought to explore whether metacognition in at-risk of developing psychosis would differ from that of first episode psychosis and unaffected controls and whether dysfunctional metacognitive beliefs would be associated with psychosocial functioning in the clinical groups.
Twenty-three subjects at-risk of psychosis were compared with a group of 15 first psychotic episode patients and 21 healthy controls with regard to their metacognitive beliefs and psychosocial functioning. Metacognition was assessed using the Metacognition Questionnaire (MCQ), psychosocial functioning was rated using the Personal and Social Performance Scale (PSP). Depression and anxiety were also evaluated.
The clinical groups differed significantly from controls in several MCQ scores, particularly the subscales "negative beliefs" and "need for control," as well as on all PSP scales. Furthermore, significant correlations emerged between the metacognition and psychosocial functioning. A mediation analysis revealed that dysfunctional metacognitive beliefs had no direct effect on psychosocial functioning, but was mediated by depressive symptoms.
These results corroborate findings assigning depressive symptoms an important role in early recognition of psychosis.
提高诊断工具包,以尽早识别有发展为精神病障碍风险的个体,这是精神分裂症研究中的一个持续挑战。在这里,我们试图探讨处于精神病风险中的个体的元认知是否与首发精神病和未受影响的对照组不同,以及元认知功能障碍是否与临床群体的社会心理功能有关。
我们比较了 23 名处于精神病风险中的个体、15 名首发精神病患者和 21 名健康对照组的元认知信念和社会心理功能。使用元认知问卷(MCQ)评估元认知,使用个人和社会表现量表(PSP)评估社会心理功能。还评估了抑郁和焦虑。
临床组在多项 MCQ 评分上与对照组有显著差异,尤其是“消极信念”和“控制需求”这两个子量表,以及 PSP 的所有量表。此外,元认知和社会心理功能之间存在显著相关性。中介分析显示,元认知功能障碍对社会心理功能没有直接影响,而是通过抑郁症状产生影响。
这些结果证实了抑郁症状在早期识别精神病中的重要作用。
