强迫症状诱发图片库的初步建立

The Initial Formulation of Chinese Obsessive-compulsive Symptom Provocation Picture System

目的：收集强迫清洗因子和强迫检查因子相关症状的诱发图片,并对其进行多维度的评定,初步建立中国强迫症状诱发图片库。方法：筛选40张图片组成强迫症状诱发图片库,23名强迫障碍患者对图片库的威胁度、愉悦度和复杂度进行了自我报告的视觉模拟评分法的评定。结果：在强迫症状诱发图片库的评定中,威胁度、愉悦度和复杂度均表现出较好的内部一致性信度,内部一致性α系数分别为：0.933,0.975,0.977;图片材料诱发患者威胁度水平显著高于愉悦度水平（t=10.78,P〈0.001）;图片材料在威胁度和愉悦度上的评分存在显著的负相关（r=-0.49,P〈0.001）;散点图显示,强迫症状诱发图片库在愉悦度和威胁度上的评分分布较为广泛。结论：中国强迫症状诱发图片库的评定结果良好,可以为强迫障碍患者的临床研究提供可靠的症状诱发材料。

Objective：To collect the obsessive checking and washing related picture to develop a standardized Chinese obsessive-compulsive symptom provocation picture system（COCSP-PS）.Methods：A total of 40 pictures were screened out to make up of COCSP-PS.23 outpatient OCD patients were collected to rate the complexity,threaten and pleasure degree by self-report in a visual analogue scale for COCSP-PS.Results：The Cronbach alpha coefficient were 0.933,0.975,0.977 on pleasure,threaten and complexity dimensions;COCSP-PS could provoke higher threaten than pleasure（t=10.78,P〈0.001）;There was negative correlation between pleasure and threaten（r=-0.49,P〈0.001）;Scatter plot showed that the score distribution on the dimension of threat and pleasure was wide in COCD-PS.Conclusion：This study establishes the Chinese obsessive checking and washing picture system for obsessive-compulsive disorder.The picture system has good reliability,can provide symptom provocation materials for native OCD-related experimental.
