  1. Data are presented as means ± SD and CI-confidence interval; the Mann–Whitney U-test was used for group comparisons (impaired vs. unimpaired). P values are expressed if they are <0.05. (AIS) Acceptance of Illness Scale, (HADS) Hospital Anxiety and Depression Scale, (BI) Barthel Index, SF-36v2 = (PF) physical functioning, (SF) social functioning, (RP) physical role functioning, (RE) emotional role functioning, (BP) bodily pain, (GH) general health, (VT) vitality, (MH) mental health, (PCS) physical component summary, (MSC) mental component summary, QLI-Quality of Life Index for Diabetes Version III = HFSUB- health and functioning subscale, SOCSUB- social and economic subscale, PSPSUB- psychological and spiritual subscale, FAMSUB- family subscale, p values are obtained by analyses using Mann–Whitney rank sum test.
