Mobile Phone Applications and Quality of Life

Participants in both groups were invited to participate after their periodical visit to the doctor or the hospital-based nurse specialised in the care for diabetes patients. All participants in this study were adults with T1DM having a smartphone. All participants will complete the The Short Form Health Survey (SF-36) and the Problem Areas In Diabetes questionnaire (PAID) at baseline and after three months of follow-up. Baseline information, including socio demographic information (age, sex, highest level of school education), and clinical characteristics (diabetes duration, insulin therapy and presence and severity of diabetes complications) will be collected in a database. Moreover parameters such as blood pressure, body weight, HbA1c and lipid profile will be added. Sample size calculation The study was powered to detect a between-group mean difference of 10 points in the The Short Form Health Survey (SF-36) questionnaire after 3 months. With a power of 80%, alpha 0.05, the total sample size of the study should be 62 patients (31 in each group).
