医学生强迫信念与强迫症状的关联分析

Relationship between obsessive beliefs and obsessive-compulsive symptoms in medical college students

目的分析医学生强迫信念与强迫症状的关联,为医学生强迫症状预防及干预提供依据。方法采用分层整群抽样方法从杭州市某医学院一至四年级各选取3~6个班级学生,采用强迫信念量表和强迫量表修订版评估强迫信念和强迫症状,采用多重线性回归模型分析医学生强迫信念与强迫症状的关联。结果调查592名医学生,回收有效问卷544份,回收有效率为91.89%。医学生强迫量表修订版总分中位数为15分,检出强迫症状157人,检出率为28.86%。医学生强迫信念量表总分为(154.11±36.05)分,其中责任感/威胁评估(RT)、完美主义/确定性(PC)和重要性/控制思维(ICT)维度得分分别为(61.12±14.53)分、(58.68±14.31)分和(32.90±10.76)分。多重线性回归分析结果显示,性别是医学生检查、清洗、强迫观念和精神中和症状的预测因素;RT是医学生囤积和强迫观念症状的正向预测因素;PC是医学生检查、排序、清洗和精神中和症状的正向预测因素;ICT是医学生囤积、检查、排序、清洗和强迫观念症状的正向预测因素(均P<0.05)。结论ICT、PC等强迫信念以及性别与医学生强迫症状存在关联。

Objective To investigate the relationship of obsessive beliefs and obsessive-compulsive symptoms in medical students and to provide evidence for prevention and intervention of obsessive-compulsive symptoms in medical students.Methods Medical students were enrolled from a medical college in Hangzhou and were selected among 3 to 6 classes from Grade One to Grade Four using stratified cluster sampling method.The students were assessed with Obsessive Beliefs Scale-44(OBD-44)and Obsessive Compulsive Scale Revised(OCD-R).Linear regression model was conducted to analyze the association between obsessive beliefs and obsessive-compulsive symptoms in medical students.Results As 592 medical students were surveyed and 544 responses were valid,the response rate was 91.89%.The median score of OCD-R of medical students was 15,and 28.86 of them had obsessive-compulsive symptoms.Concerning OBD-44,the total score of medical students was 154.11±36.05,the scores of responsibility/threat,perfectionism/certainty and importance/control of thoughts were 61.12±14.53,58.68±14.31 and 32.90±10.76,respectively.The Linear regression analysis demonstrated that gender could predict checking,washing,obsessing and neutralizing;responsibility/threat estimate predicted hoarding and obsessing;perfectionism/certainty was the most significant predictor of checking,ordering,washing,neutralizing;and importance/control of thoughts predicted hoarding,checking,ordering,washing and obsessing(all P<0.05).Conclusion Gender,importance/control of thoughts and perfectionism/certainty have significant impact over most of obsessive-compulsive symptoms in medical students.
