摘要: 目的: 评估压力知觉量表(PSS-10中文量表)应用于复发性阿弗他溃疡的效度和信度。方法: 采用方便抽样的方法,选取155例复发性阿弗他溃疡进行现场问卷调查。采用内部一致性信度、复测信度检验其信度;采用探索性因子分析和验证性因子分析的方法检验PSS-10中文量表的结构效度,选用HADS作为效度检验效标效度。结果: 探索性因素分析获得无助感和自我效能感2个因子,累计解释量表总方差变异的70.42%;验证性因素分析验证了双因素模型(χ2/df=1.98,CFI=0.96,NNFI=0.93,RMSEA=0.08,RMSR=0.09)。量表的内部一致性系数为 0.72,其中无助感的内部一致性系数为0.90,自我效能感的内部一致性系数为0.89。PSS-10中文量表与HADS相关显著(P<0.01),显示较好的效标关联效度。相关性分析显示女性在无助感和自我效能感上均高于男性;不同类型的RAU患者在无助感和自我效能感上具有明显差异,其差异性具有统计学意义。结论: 压力知觉量表具有良好的效度和信度,可将其作为自评工具用于评估复发性阿弗他溃疡的压力程度。

Abstract: Objective: To evaluate the validity and reliability of the perceived stress scale (PSS-10) in recurrent aphthous ulcer. Methods: Using convenient sampling method, 155 cases of recurrent aphthous ulcer were investigated by on-the-spot questionnaire. Internal consistency reliability and test-retest reliability were used to test its reliability. Exploratory factor analysis and confirmatory factor analysis were used to test the construct validity of PSS-10, and HADS was selected as the criterion validity. Results: Two factors of helplessness and self-efficacy were obtained by exploratory factor analysis, which cumulatively explained 70.42% of the total variance of the scale. Confirmatory factor analysis verified the two-factor model (χ2/df=1.98, CFI=0.96, NNFI=0.93, RMSEA=0.08, RMSR=0.09). The internal consistency coefficient of the scale was 0.72, in which the internal consistency coefficient of helplessness was 0.90, and the internal consistency coefficient of self-efficacy was 0.89. There was a significant correlation between PSS-10 and HADS, showing a good criterion correlation validity. Correlation analysis showed that women were higher than men in sense of helplessness and self-efficacy. Different types of RAU patients had significant differences in sense of helplessness and self-efficacy (P<0.05). Conclusion: The perceived stress scale has good validity and reliability and can be used as a self-assessment tool to evaluate the stress degree of recurrent aphthous ulcer.
