目的编制梦威胁事件问卷(DTQ),并检验其信度和效度。方法根据梦威胁模拟理论的框架,结合对20名正常者及20名神经症和抑郁症病人的面谈结果,形成初步的梦威胁事件问卷条目,在484名正常者、166名经历汶川地震的医务人员及121名精神障碍病人中进行测评,作信效度分析。结果信度检验:DTQ内部一致性系数为0.799,分半信度为0.775,重测信度为0.872。效度检验:因素分析产生一个因子,解释总方差的37.5%,各条目因素载荷在0.41～0.75之间,并且具有较好的跨样本一致性。验证性分析显示被验证模型结构合理。DTQ分与梦日记中威胁性梦的比率(r=0.69,P<0.001)和梦频率问卷中的噩梦频率(r=0.54,P<0.001)呈正相关。心理创伤者(2.2±2.4)在DTQ上的得分大于非创伤者(1.3±1.9)(P=0.003)。结论梦威胁事件问卷具有较好的信度和效度,可用于中国人群梦的威胁水平评估。
Objective To prepare a dream threat event questionnaire (DTQ) and test its reliability and validity. Methods Based on the framework of dream threat simulation theory and the interviews with 20 normal subjects and 20 neurosis and depression patients, preliminary questionnaire items of dream threat events were formed. Among 484 normal subjects and 166 medical staffs who experienced the Wenchuan earthquake Personnel and 121 patients with mental disorders were evaluated for reliability and validity analysis. Results reliability test: DTQ internal consistency coefficient of 0.799, fractional half reliability is 0.775, test-retest reliability is 0.872. Validity test: The factor analysis produces a factor that accounts for 37.5% of the total variance with a load of 0.41 to 0.75 for each item and has good cross-sample consistency. Confirmatory analysis shows the structure of the validated model is reasonable. There was a positive correlation between DTQ score and the threatening dream rate in the diary (r = 0.69, P <0.001) and the nightmare frequency (r = 0.54, P <0.001) in the dream frequency questionnaire. Patients with trauma (2.2 ± 2.4) scored more on DTQ than non-trauma (1.3 ± 1.9) (P = 0.003). Conclusion The questionnaire of dream threat events has good reliability and validity and can be used to evaluate the threat level of Chinese people’s dreams.
