神经症患者持续性操作测验的研究

The study of continuous performance test in neurotic patients

目的:探索神经症患者持续性注意功能的特征。 方法:对34例神经症患者和37例正常对照者进行了持续性操作测验(CPT)检查。 结果:神经症患者几乎所有的CPT指标都显著高于正常对照组。在从易到难、依次进行的3个分测验中,和正常对照组相似。各类神经症患者间CPT指标差异均无显著性。90项症状清单(SCL-90)部分指标与复杂操作中的反应时间呈正相关(P<0.05～0.01)。CPT指标与某些精神药物等效剂量之间无显著相关。 结论:神经症患者存在着某种程度的持续性注意障碍,但具有正常人的某些特征。

Objective: To explore the feature of sustained attention in neurotic patients. Method: 34 cases of neurotic patients and 37 normal controls were examined with continuous performance test (CPT). Results: Most of CPT parameters in neurotic patients were higher than those of the normal controls. No significant difference was found in CPT parameters among sub-types of neurotic patients. There were positive correlations between some of the scores of symptom checklist 90 (SCL-90) and CPT parameters( P < 0.05 ~ 0.01). No significant correlation was found between CPT parameters and the dosage of some psychotropic drugs. Conclusion: There were some dysfunction of sustained attention in neurotic patients, which had some of the features in normal persons.
