目的 探讨伴述情障碍的精神分裂症患者的基于事件前瞻记忆(EBPM)和基于时间前瞻记忆(TBPM)的特点,为认知功能干预提供理论依据.方法 对30例符合入组标准的伴述情障碍的精神分裂症患者以及年龄、性别、受教育程度相匹配的30名精神分裂症患者实施前瞻记忆的神经心理学测试.结果 伴述情障碍的精神分裂症患者组EBPM评分为(3.80±0.85)分,对照组EBPM评分为(4.10±0.71)分,两组比较差异无统计学意义(t=-1.485,P=0.143),伴述情障碍的精神分裂症患者组TBPM评分为(3.33±1.09)分,对照组TBPM评分为(3.93±0.83)分,两组比较差异有统计学意义(t=-2.397,P=0.02).结论 伴述情障碍的精神分裂症患者相对非述情障碍的精神分裂症患者存在更严重的基于时间前瞻记忆功能损害.“,”Objective To investigate the event-based prospective memory (EBPM)and time-based prospective memory(TBPM) in schizophrenia patients with alexithymia,and to provide theoretical basis for early intervention and treatment.Methods According to inclusion standard,30 schizophrenia patients with alexithymia and 30 schizophrenia patients without alexithymia matched in age,gender and education were assessed with a neuropsychological battery of tests including EBPM and TBPM tasks.Results In the EBPM task,there was no significant difference between schizophrenia patients with and without alexithymia (3.80±0.85 vs 4.10±0.71,t=-1.485,P=0.143).A statistically significant in TBPM was observed between schizophrenia patients with and without alexithymia (3.33±1.09 vs 3.93±0.83,t=-2.397,P=0.02).Conclusion The schizophrenia patients with alexithymia have more severe time-based prospective memory impairment than those without alexithymia.
