Abstract:
Objective:To develop Insulin Pen Waste Needles Disposal Behavior Scale for Diabetic Patients and test its reliability and validity.Methods:Using the model of information, motivation and behavior skills as the theoretical framework, the item pool was constructed by literature review, semi-structured interview and expert consultation, and the test scale was formed after a small sample pre-survey. In July 2022, 158 and 204 diabetes patients who self-injected insulin in Endocrinology Outpatient Department of a general hospital in Shanghai were selected by the convenient sampling method. Two questionnaires were conducted to test the reliability and validity of the scale.Results:Insulin Pen Waste Needles Disposal Behavior Scale for Diabetic Patients included four dimensions, such as disposal behavior cognition, disposal behavior motivation, disposal behavior skills, and safe disposal behavior, with a total of 16 items. Four common factors were extracted from exploratory factor analysis, and the cumulative variance contribution rate was 73.80%. Content validity index was 0.98 at the average scale level, 0.88 at the level of unanimity scale, and 0.83-1.00 at the level of each item. The results of confirmatory factor analysis showed that the scale structure was stable. The Cronbach's α coefficient of the scale was 0.908, the Cronbach's α coefficient of the four factors was 0.858-0.901, the split half reliability coefficient was 0.941, and the retest reliability coefficient was 0.819.Conclusions:The scale constructed in this study has good reliability and validity, which can provide a scientific and effective assessment tool for medical staff to evaluate the disposal behavior of discarded needles used for insulin pens in diabetic patients.
