摘要目的 探讨修订版元认知量表在精神分裂症和神经症患者中的应用.方法 通过印第安精神疾病访谈,采用修订版元认知量表(MAS-A)对115例精神分裂症患者和89例神经症患者进行评估,比较两组间MAS-A评分差异,评估区分效度;同时采用心理理论图片任务(ToM-PST)测量被试心理理论水平,以ToM-PST总分作为效标,计算效标关联效度;首测1个月后抽取34例精神分裂症和31例神经症患者进行重测,评估重测信度.结果 (1)信度分析:总样本、分裂症组和神经症组MAS-A的Combachα系数分别为0.829、0.826、0.823.总样本MAS-A总分及其自我反省、理解他人、去中心化和控制因子分的重测信度分别为0.722、0.541、0.650、0.615、0.525,具有统计学意义(均P＜0.01).(2)效度分析:总样本、分裂症组和神经症组MAS-A总分与ToM-PST总分间的相关系数分别为0.470、0.383、0.292,均差异具有统计学意义(均P＜0.01);与神经症患者相比,精神分裂症患者MAS-A总分及各因子分明显较低,差异有统计学意义(均P＜0.01).结论 修订版元认知量表的信度和效度尚可,可用于精神疾病人群的元认知能力评估.

abstractsObjective To explore the application of the abbreviated metacognitive assessment scale (MAS-A) in patients with schizophrenia and neurosis.Methods With the aid of the Indiana Psychiatric Ill-ness Interview (IPII),115 schizophrenic patients and 89 neurotic patients were assessed using the MAS-A,and compared the group difference of MAS-A scores.All patients were also tested with the theory of mind picture sequencing task (ToM-PST).The criterion-related validity was evaluated using of correlated MAS-A total-score with ToM-PST total-score.31 neurotic patients and 34 schizophrenic patients were measured after one month to compute the test-retest reliability.Results The reliability analysis showed that the Cronbach α-coefficients for MAS-A of total sample,schizophrenic group and neurotic group were 0.829,0.826,0.823,respectively.The test-retest reliability of MAS-A and four factors were 0.722,0.541,0.650,0.615 and 0.525 (all P＜0.01).The validity analysis also showed that the correlation coefficient between the total scores of MAS-A and ToM-PST were 0.470,0.383,0.292 (all P＜0.01) in total sample,schizophrenia and neuroses patients,respectively.Additionally,the scores of MAS-A of schizophrenia patients were significantly lower than that of neurotic patients.Conclusion MAS-A has good reliability and validity and is a valuable tool in application to metacognitive assessment for chinese mental population.
