摘要
目的:探讨精神分裂症患者与分裂型人格个体的时间加工行为特征。方法:选取59名符合美国精神障碍诊断与统计手册第4版(DSM-IV)精神分裂症诊断标准的门诊或住院患者,62名通过分裂型人格问卷(SPQ)筛查的分裂型人格个体以及60名健康对照人群。通过时间辨别任务、时间产生任务、时间复制任务对3组被试的时间加工能力进行测查。结果:时间产生任务中,分裂型人格组的准确性得分大于健康对照组[(1.03±0.07)vs.(0.99±0.09),P<0.05],精神分裂症组的变异系数大于健康对照组和分裂型人格组[(0.26±0.10)vs.(0.20±0.05),(0.20±0.05);均P<0.01];时间复制任务中,精神分裂症组的变异系数大于健康对照组和分裂型人格组[(0.21±0.11)vs.(0.15±0.07),(0.17±0.12);均P<0.01)。结论:精神分裂症患者和分裂型人格个体都存在时间加工表现上的缺损,其中精神分裂症患者的缺损可能更为严重。
Objective: Schizophrenia is associated with time-processing impairments. However, very little is known about this type of problem in at-risk individuals with schizotypal personality disorder (SPD) features. The current study compared time-processing performance in patients with schizophrenia, individuals with SPD features, and healthy controls. Methods: A number of tasks capturing time discrimination, time production and time reproduction as well as other related abilities were administered to 59 schizophrenia patients, 62 individuals with SPD fea- tures, and 60 healthy controls. The diagnosis was made according to the Diagnostic and Statistical Manual of Mental Disorders-IV, Fourth Edition (DSM-IV) criteria. In analyzing the time-processing data, repeated measures were a- dopted, with group as a between-subjects variable, duration of time as a within-subjects variable, time threshold in time discrimination, accuracy (estimated time/standard time) and coefficient of variation (SD of estimated time/ mean of estimated time) of time production and time reproduction as dependent variables. Results: The result showed that patients with schizophrenia, SPD individuals and healthy controls had similar time discrimination threshold (P 〉 0. 05). In the time production task, SPD individuals had higher accuracy score than healthy controls [ ( 1.03 ±0. 07) vs. (0. 99± 0. 09), P 〈 0. 05 ], while patients with schizophrenia had higher coefficient of variation as compared to individuals with SPD features and healthy volunteers[(0. 26 ±0. 10) vs. (0. 20 ±0. 05), (0. 20 ± 0. 05) ; Ps 〈 0. 01]. In the time reproduction task, patients with schizophrenia also scored higher on the coefficient of variation than SPD individuals and healthy controls[ (0.21 ± 0. 11) vs. (0. 15± 0.07), (0. 17 ±0. 12); Ps 〈0. 01]. Conclusion: The current findings suggest that both SPD individuals and patients with schizophrenia may have impairments on time processing. The impairment
