伴述情障碍的精神分裂症患者的抑制控制

目的:研究伴述情障碍的精神分裂症患者的抑制控制功能。方法:对50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50名精神分裂症患者实施Stroop色词测验。结果:与对照组相比,伴述情障碍的精神分裂症患者Stroop色词测验卡片C反应时长于对照组(t=3.104,P0.01)、正确阅读数低于对照组(t=-2.882,P0.01);卡片A反应时、正确阅读数差异均无统计学意义(t=1.285,-0.995;P0.05),卡片B反应时与对照组差异无统计学意义(t=1.81,P0.05),正确阅读数差异无统计学意义(t=-1.247,P0.05)。与对照组相比,伴述情障碍的精神分裂症患者干扰量高于对照组(t=2.264,P0.05)。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抑制控制功能损害,临床工作中应给予针对性的认知干预,将有助于促进康复。

Study on Inhibitory Control in Schizophrenia Patients with Alexithymia

Objective :To investigate inhibitory control in schizophrenia patients with alexithymia .Methods :Accord‐ing to inclusion standard ,50 schizophrenia patients with alexithymia and 50 schizophrenia patients without alexithy‐mia matched in age ,gender and education were assessed with the Stroop test .Results :Compared with control group , significant differences were observed in the reaction time and correct reading number in part C (t = 3 .104 ,‐2 .882 ;P <0 .01) .Stroop color - word test showed that the reaction time and correct reading number in part A had no statistical ‐ly significant between schizophrenia patients with and without alexithymia (P > 0 .05) .The reaction time and correct reading number of schizophrenia patients with alexithymia in part B were not longer than schizophrenia patients without alexithymia (P > 0 .05) .Compared with control group ,the interference quantity of schizophrenia patients with alexithymia was higher than schizophrenia patients without alexithymia (t = 2 .264 ,P < 0 .05) .Conclusion :The schizophrenia patients with alexithymia have severer inhibitory control impairment than those without alexithymia , and they need intervention to promote rehabilitation .
