目的:分析宫颈癌筛查信念量表的信度和效度,评价其对宫颈癌筛查的价值。方法:以侯书逸开发的宫颈癌筛查信念量表为蓝本,修订形成中文版宫颈癌筛查信念量表。采用自填式信念量表调查1 575名社区妇女,使用内在一致性信度分析和因子分析对该问卷的信度与效度进行分析。结果:使用内在一致性信度分析将该量表修订为23个条目,修正过的量表的克朗巴哈α系数为0.939,说明量表信度较高。因子分析中KMO统计量为0.942,数据适合做因子分析。选择特征根大于1的因子生成4个量表维度,结合信念理论分别定义为“健康威胁知觉”、“行为好处知觉”、“主观行为准则”和“行动障碍知觉”。结论:问卷具有较好的信度和效度,适宜在中国城市社区妇女中使用。
Objective: To analyze the reliability and validity of cervical cancer screening belief scale and evaluate its value in cervical cancer screening. Methods: Based on the Scale of Belief in Cervical Cancer Screening developed by Hou Shiyi, the revised Chinese version of Cervical Cancer Screening Scale was revised. A total of 1,575 women in the community were surveyed using a self-administered belief scale and the reliability and validity of the questionnaire were analyzed using internal consistency reliability analysis and factor analysis. RESULTS: This scale was revised to 23 entries using the internal consistency reliability analysis, and the Cronbach’s alpha coefficient of the revised scale was 0.939, indicating a high reliability of the scale. The KMO statistic in factor analysis is 0.942, and the data is suitable for factor analysis. We select four factors of eigenvalues greater than 1 to generate four scales, which are defined as “health threat perception ”, “behavioral benefit perception ”, “subjective behavior criterion ” and “obstacle perception ”. Conclusion: The questionnaire has good reliability and validity and is suitable for use in Chinese urban community women.
