简式简明心境问卷在癌症病人应用中的信、效度

Reliability and Validity of Profile of Mood State-Short Form in Chinese Cancer Patients

目的 :了解简式简明心境问卷 (POMS- SF)在癌症病人中的适用情况和心理测量学指标。方法 :采用随机分组的方法将 2 89名癌症病人分成干预组和对照组 ,分别在治疗前中后测查三次 POMS- SF,同时测查 385名正常被试。结果 :POMS- SF项目与总分的相关为 0 .36～ 0 .81(P<0 .0 1) ,α系数为 0 .5 9～ 0 .93。效度分析显示 ,治疗后干预组情绪状况显著好于对照组 (P<0 .0 1) ,早期病人情绪状况要好于晚期病人 ,POMS- SF各量表与 POMS相应量表间相关为 0 .95～ 0 .99(P<0 .0 1)。因素分析显示 ,按照特征根大于 1的标准 ,提取出 6个公因子 ,与原量表的构想一致。结论 :POMS- SF在癌症病人使用中的区分度、信度和效度指标都达到了心理测量学的要求 ,适合于临床上癌症病人情绪状况的测查。

Objective:To evaluate the profile of mood state-short form (POMS-SF) in Chinese cancer patients. Methods:289 cancer patients were randomly assigned to experimental or control group, both groups were assessed three times (pre-, on-and post-treatment ). 385 normal people were also completed the questionnaire. Results:The correlation between the items and the TMD of the scale ranged from 0.36～0.81 (P<0.01). The alpha coefficient ranged from 0.59～0.93. For the validity, the mood states of the patients from experimental group were better than those from control group in post-treatment (P<0.01), early cancer patients had better mood than terminal patients; the correlation between the POMS-SF and the POMS ranged from 0.95～0.99(P<0.01); factor analysis extracted 6 factors,which accorded with the structure of the scale.Conclusion:The discrimination, reliability and validity of the POMS-SF are satisfactory when applied to Chinese cancer patients.
