To develop and validate Health Related Quality of Life Questionnaire in Diabetic Foot Ulcer Patients (HRQLQDFU) for Indian scenario.
This study was conducted in two phases. First phase was Development of HRQLQDFU which included literature search and expert interview. Second phase was validation of HRQLQDFL which included face validation, content validation and construct validation. Face validation was done by ten diabetic foot ulcer patients, ten practicing nurses and ten care givers. They were asked to read and respond to questionnaire and report any difficulty in understanding the questions. Further they were asked to add any item to the questionnaire which according to them has a significant effect on quality of life. Content validation was done by six subject experts who judged the content relevance of questionnaire with score ranging from zero to four; zero being least relevant and four being most relevant. Content validity index was calculated for each question. Questions having content validity index≥0.8 were selected for the study. Reliability was tested by calculating Cronbach's alpha.
In the development phase a questionnaire containing 37 questions with six domains was developed. None of patient had difficulty in understanding questions. After content validation a new questionnaire containing 20 questions was developed. Cronbach's alpha was 0.86 which shows good reliability.
The new health related quality of life questionnaire on diabetic foot ulcer patients for an Indian scenario is validated and can be a reliably measure for quality of life in diabetic foot ulcer patients.
针对印度的情况，开发并验证糖尿病足溃疡患者健康相关生活质量问卷（HRQLQDFU）。
本研究分两个阶段进行。第一阶段是HRQLQDFU的开发，包括文献检索和专家访谈。第二阶段是HRQLQDFU的验证，包括表面效度验证、内容效度验证和结构效度验证。表面效度验证由10名糖尿病足溃疡患者、10名执业护士和10名护理人员完成。要求他们阅读问卷并做出回答，报告理解问题时遇到的任何困难。此外，要求他们在问卷中添加任何他们认为对生活质量有显著影响的项目。内容效度验证由6名主题专家进行，他们对问卷的内容相关性进行评分，范围从0到4；0表示相关性最低，4表示相关性最高。计算每个问题的内容效度指数。选择内容效度指数≥0.8的问题进行研究。通过计算Cronbach's alpha来测试信度。
在开发阶段，编制了一份包含37个问题、六个领域的问卷。没有患者在理解问题上有困难。经过内容效度验证后，编制了一份包含20个问题的新问卷。Cronbach's alpha为0.86，显示出良好的信度。
针对印度情况的新的糖尿病足溃疡患者健康相关生活质量问卷得到了验证，可作为糖尿病足溃疡患者生活质量的可靠测量工具。
