Evaluation And Clinical Application Of The Chinese Version Of The Personal Diabetes Questionnaire

Objective: Introduce and revise the Personal Diabetes Questionnaire(PDQ).Analyze the reliability and validity of the Chinese version. Provide a good tool for therapid assessment of the diabetics self-management education effect and problems.Investigate the self-management problems of the type2diabetics. Analyze their impactfactors and develop a scientific and rational type2diabetes health management program.Method: Through translation,back translation,cultural adjustment,etc.,introdu-ce the Personal Diabetes Questionnaire (PDQ) to localize it. Select30eligiblepatients with diabetes in a tertiary hospital in Qingdao to make a preliminaryinvestigation. The reliability analysis includes Cronbach’s alpha coefficient andtest-retest reliability. The validity analysis includes content validity and criterionvalidity. Convenience sampling method was uesed to obtain210outpatients withdiabetes from two tertiary hospital in Jinan and Qingdao,surveyed with the Chineseversion of PDQ. Spss16.0was used to do the statistical analysis,including thedescriptive analysis,t-test,analysis,correlation analysis,Kruskal Wallis rank analysis.Results:1.The questionnaires are all taken back. The response rate is100%. All itemsare all qualified. There are some items which need guidance. The Chinese version ofPDQ and its dimensions have good reliability,whose total internal consistencycoefficient is0.831and test-retest reliability is0.801. The questionnaire has goodvalidity. Total Content Validity Index is0.938. I-CVI is between0.800and1.000. The questionnaire’s dimensions have parallel validity with glycosylated hemoglobin(HbA1c) and body mass index (BMI). Eating problems and barrier dimensions havepositive correlation with HBA1c. Knowledge and skills of diet and diet decisionshave negative correlation with HBA1c(P<0.01or0.05). Knowledge and skills of dietand diet decisions are negatively correlated with BMI. Barrier dimensions aresignificantly positively correlated with BMI(P<0.01or0.05).2.Through investigation,the Type2diabetics’ self-management was insufficient.Their level of knowledge and skills of diet was not high(respectively18.41and19.00,total points45). They didn’t exactly follow doctor’s advices on diet,exercise,blood glucose monitoring and medication. Insulin treatment group was more likelyto end up taking drugs or injecting insulin. Non-insulin treatment group’simplementation rate of measuring blood sugar was less than insulin treatment group.There existed different obstacle factors,and the two groups on exercise barriers andblood glucose monitoring barriers were significantly different(P<0.05).91.42%ofpatients were recommended to do more exercise. Actually21.63%(non-insulintreatment group),27.94%(insulin treatment group) of the patients had no activities.About half of patients could’t meet the requirements of2010new diabetes activitiesguidelines.Conclusions: The personal diabetes questionnaire introduced by this researchhas good reliability and validity,and can be widely used in future clinical. The Type2diabetics’ knowledge,skills and attitude about self-management need to beimproved. The barriers of exercise,diet,medication and blood glucose monitoringare different. So the educators need to improve the patients’ self-care knowledge,skills and compliance according to the physical,psychological and social factors.
