女性压力性尿失禁患者健康信念量表的编制

Development and psychometric test of Health Belief Scale for female patients with stress urinary incontinence

目的编制用于评价女性压力性尿失禁患者的健康信念量表,并检验其信效度。方法以健康信念模式为理论框架,通过文献回顾和专家咨询设计初始量表。经专家内容效度评定、预调查和统计学分析等过程对量表条目进行修订和筛选,形成正式量表,然后对量表的信度和效度进行评价。结果正式量表包括4个维度:罹患性认知(3个条目)、严重性认知(12个条目)、障碍性认知(8个条目)和利益性认知(7个条目),共30个条目。量表中每个条目均具有较好的鉴别度,量表的内部一致性信度Cronbach'sα系数为0.97,重测信度为0.95。量表的内容效度为0.97,其4个维度用主成分分析均抽取了特征值大于1的公因子1个,每个公因子的贡献率均大于50%,每个条目在各自公因子上的载荷值均大于0.4。结论编制的女性压力性尿失禁患者健康信念量表具有良好的信度和效度,可用于评价女性压力性尿失禁患者的健康信念水平。

Objective To develop an instrument to assess the health belief of female patients with stress urinary incontinence,and to test its reliability and validity. Methods Based on the health belief model,literature review and expert consultation,a draft scale was developed. The items were revised and selected by expert counseling,pilot investigation and statistical methods. Then,the reliability and validity were tested among 192 female patients with stress urinary incontinence. Results The final scale consisted of 30 items in 4 dimensions,including perceived susceptibility （3 items）, perceived seriousness （ 12 items）, perceived barriers （ 8 items） and perceived benefits （ 7 items）. Each item in the scale had good discrimination. The Cronbach＇s α coefficient of the scale was 0.97 and the testretest reliability was 0.95. The content validity index of the scale was 0.92. The factor load of each item was over 0.4 and the contribution rate of factors was over 50%. Conclusion The Health Belief Scale for female patients with stress urinary incontinence has good reliability and validity. It can be used to assess the health belief of female patients with stress urinary incontinence.
