Abstract
- Aims: To develop and validate an easy-to-use questionnaire to identify obstacles to self management in Type 2 diabetes.<br />Methods: The Diabetes Obstacles Questionnaire (DOQ) was developed from earlier research and the literature. It was completed by 180 people with Type 2 diabetes, recruited from 22 general practices in the UK. Responders also completed a quality-of-life questionnaire (ADDQoL) and the Problem Areas in Diabetes (PAID) scale.<br />Results: From analysis of the 176 usable questionnaires, 36 items of the original 113 items were deemed redundant. The remaining 77 items were assembled into eight sub-scales covering Medication, Self Monitoring, Knowledge and Beliefs, Diagnosis, Relationships with Health-Care Professionals, Lifestyle Changes, Coping, and Advice and Support. Each sub-scale had a factor structure of no more than three factors, had Cronbach's alpha of more than 0.75, and a Kaiser-Meyer-Olkin of more than 0.75. Each sub-scale correlated significantly with the PAID scale (P < 0.01), demonstrating criterion validity. Construct validity was shown by significant correlation between HbA(1c) and the sub-scales which relate to managing blood glucose levels: Self Monitoring, Relationship with Health-Care Professionals, Lifestyle Changes and Coping. Construct validity was further shown by significant correlation between QoL scores and Medication, Lifestyle Changes and Coping.<br />Discussion: The DOQ, comprising eight sub-scales, is a usable, valid instrument for both clinical and research settings. It helps to identify in detail the obstacles which an individual finds in living with Type 2 diabetes.
