Validity and Reliability of the 19-item Audit of Diabetes-Dependent Quality of Life (ADDQoL-19) Questionnaire in Chinese Patients with Type 2 Diabetes Mellitus in Primary Care

Background: This study aimed to determine the psychometric properties of the 19-item ADDQoL (ADDQoL-19) in Chinese patients with Type 2 diabetes mellitus (T2DM) in primary care setting. Methods: The ADDQoL-19 and SF-12v2 were administered to 386 Chinese patients with T2DM in public primary outpatient clinic in Hong Kong. Internal consistency reliability was determined by Cronbach’s alpha whereas construct validity was assessed by the Spearman’s correlations between the scores of the ADDQoL-19 and SF-12v2. Independent t-tests were used in known-groups comparisons to identify the differences in the ADDQoL-19 scores between respondents with different duration of diabetes, treatment modalities, body mass index and glycemic control. Results: The ADDQoL-19 had a moderate to weak correlation with SF-12v2 in convergent validity but with statistically significant results in known-groups comparisons. Good internal consistency was generated with an acceptable value of 0.81, which was comparable to original English version. Construct validity was proven except the convergent validity is found to be weak with the generic SF-12v2, which was similar to the results in prior psychometric studies. Conclusions: Despite weak convergent validity, the ADDQoL-19 was found to have a satisfactory psychometric property especially known-groups comparisons and internal consistency reliability in the primary care setting.postprin

A qualitative study of the views on weight management in overweight and obese Chinese diabetic patients

Conference Theme: Stay Caring, Go Excelling in Primary CareFree Paper Competition – Poster Presentation 13 (abstracts)INTRODUCTION Weight reduction was found to be associated with improved glycemic control among overweight and obese adults with type 2 diabetes mellitus (DM). However, obesity and overweight remains a significant problem for diabetic patients, as their motivating factors and barriers for weight reduction are diverse and complex. This qualitative study aims to investigate the motivating factors and barriers in weight control among obese DM patients. METHOD Twenty in-depth semi-structured interviews with obese or overweight diabetic patients under the care of Ap Lei Chau Clinic were conducted in 2013/2014. Issues like perceived barriers, facilitators, and their experience in weight and DM management were explored. All the interviews were audio-taped and transcribed into English, typed verbatim. Grounded theory approach was adopted and saturated data were analyzed thematically. RESULTS Four key themes were identified: (1) patients’ medical conditions, (2) psychological factors, (3) social support and (4) lifestyle habits. Co-morbidities like OA knee hinder regular exercise. Self-perception of health and weight influences the compliance to weight control. Dieting is preferred over exercise for weight reduction. Social and family support can assist patients to monitor their weight and facilitate adherence to appropriate choices and amount at meals. Patients who tried nutritional counselling before often considered the advice form dietitians are unpractical and difficult to apply. DISCUSSION Lifestyle modifications play a significant role in weight management of DM patients. However, patients’ self-perception and support from family is equally important. Nutritional counselling should be more tailor-made for individual patients, and considering of co-morbidities is equally crucial
