非精神科临床医师心理卫生知识调查问卷的初步编制

Development and evaluation of questionnaire of mental health knowledge fornon-psychiatric clinicians

目的:了解非精神科临床医师对心理卫生知识的知晓程度,编制适用的调查问卷。方法:方便选取北京市2家三级综合性医院,2家二级综合性医院,1家社区医院的共641名非精神科临床医师进行项目分析、内部一致性检验,并选取其中38例进行间隔2周的重测,以检验重测信度。对作者所在单位三级精神病专科医院的99名医师进行调查,计算其对心理卫生知识的知晓率,并与综合医院样本进行比较。结果:(1)问卷保留46题,包括6个维度,分别为焦虑症状及神经症相关问题、精神分裂症相关问题、抑郁障碍、失眠与心理咨询相关问题、脑器质性障碍、对综合医院心理卫生问题现状的认识。对6维度模型进行验证性因素分析,结果显示卡方与自由度之比小于3,误差项RMSEA与SRMR均<0.08,各种拟合指数除GFI和AGFI外,均>0.90。(2)问卷Cronbachα系数在0.73～0.89之间,重测Pearson相关系数在0.59～0.78之间。(3)综合医院受试对心理卫生知识总的知晓率低于专科医院受试(47.6%vs.90.9%,P<0.001)。结论:问卷结构符合编制要求,有较好信效度,能在一定程度上反映客观状况,可在临床中试用。

Objective： To develop the mental health knowledge questionnaire in order to know about the awareness of mental health knowledge in non-psychiatric clinicians. Methods： A sample of the 641 non-psychiatric clinicians from 2 tertiary general hospitals, 2 second-class general hospitals, and 1 community hospital were used for item analysis and internal consistency test; 38 cases were selected for the re-test interval of 2 weeks to test the test-retest reliability. And totally 99 psychiatrists finished the survey as controls. The awareness rates between the non-psychiatric and psychliatric clinicians were compared. Results： The questionnaire included 46 items and consisted of 6 subscales, involving anxiety, schizophrenia, depression, dyssomnia and psychological counseling, organic brain disorder, and recognition for mental health service situation in general hospital. The results of confirmatory factor analysis showed that the ratio of chi-square and degree of freedom was below 3. The fitting indexes except GFI and AGFI were more than 0.90. The Cronbach＇ s alpha coefficients ranged from 0. 73 to 0. 89, and test-retest Pearson correlation coefficient of reliability ranged from 0. 59 to 0. 78. Awareness rate was 47. 6% in general hospital and 90. 9% in psychiatric hospitals. Conclusion： The mental health knowledge questionnaire has good psychometric properties and may be applied in clinical studies.
