目的评价糖尿病患健康促进量表(T2DHPS)的信度和效度,为该量表在中国大陆人群的推广使用提供科学依据。方法于2015年5月—2016年4月采用连续定点抽样方法在山西省长治医学院2家直属附属医院抽取180例2型糖尿病患者进行T2DHPS量表面访调查;采用Cronbach’sα系数和分半信度评估量表的信度,采用探索性因子分析、区分效度和集合效度评估量表的效度。结果 T2DHPS量表的总体Cronbach’sα系数为0.943,分半信度为0.935;运动行为、风险规避行为、压力处置行为、生命欣赏行为、健康责任行为、健康饮食行为6个维度的Cronbach’sα系数分别为0.931、0.832、0.838、0.887、0.819、0.842,分半信度分别为0.897、0.741、0.802、0.765、0.669、0.707,量表具有较好的信度;探索性因子分析结果显示,T2DHPS量表符合预设的6个因子结构,累计方差贡献率为70.266%;T2DHPS量表运动行为、风险规避行为、压力处置行为、生命欣赏行为、健康责任行为、健康饮食行为6个维度的平均分分别为(16.0±7.6)、(17.5±6.6)、(14.7±5.4)、(11.2±3.6)、(8.6±3.8)、(9.7±3.5)分,集合效度均高于区分效度,量表具有较好的效度。结论 T2DHPS量表在中国大陆人群中的信度和效度指标均符合心理测量学的要求,可适用于中国糖尿病患者健康促进效果的评估。
Objective To evaluate the reliability and validity of Diabetes Mellitus Health Promotion Scale (T2DHPS), and provide a scientific basis for the promotion and use of this scale in mainland China. Methods From May 2015 to April 2016, 180 patients with type 2 diabetes mellitus (T2DHPS) were interviewed in two affiliated hospitals of Changzhi Medical College of Changzhi Medical College from May 2015 to April 2016 by continuous point sampling method. The Cronbach’s alpha coefficient and half-letter To assess the reliability of the scale, exploratory factor analysis, discriminant validity and set validity were used to evaluate the validity of the scale. Results The overall Cronbach’s α coefficient of T2DHPS scale was 0.943, with a half-confidence level of 0.935. The Cronbach’s alpha coefficient of 6 dimensions including exercise behavior, risk aversion behavior, stress management behavior, life appreciation behavior, health responsibility behavior and healthy diet behavior Respectively, 0.931,0.832,0.838,0.887,0.819,0.842, points of half reliability were 0.897,0.741,0.802,0.765,0.669,0.707, the scale has a good reliability; exploratory factor analysis showed that the amount of T2DHPS The table accords with the preset six factor structure, and the cumulative variance contribution rate is 70.266%. The average scores of the six dimensions of the exercise behavior, risk aversion behavior, stress management behavior, life appreciation behavior, health responsibility behavior and healthy eating behavior of T2DHPS scale are respectively (16.0 ± 7.6), (17.5 ± 6.6), (14.7 ± 5.4), (11.2 ± 3.6), (8.6 ± 3.8), (9.7 ± 3.5) points respectively. The pooled validity was higher than discriminant validity, Has good validity. Conclusions The reliability and validity of T2DHPS scale in Chinese population are in line with the requirements of psychometrics and can be applied to evaluate the health promotion effect of diabetes in China.
