Sense of coherence and power among people with blindness caused by diabetes.

The aim of the present study was to analyze whether strong sense of coherence (SOC) or power or the combination of strong SOC and power was related to blind diabetic patients' self-perceived health, burden of diabetes, glycaemic control and self-care among blind people. In some variables we wanted to compare subjects with diabetes-related blindness with people who were blind for other reasons than diabetes. The present descriptive study included 39 blind subjects from three ophthalmic outpatient clinics who agreed to participate; 23 were blind due to diabetes and 16 were blind for other reasons. Power was explored during semi-structured interviews, SOC was measured with the SOC-scale and burden of diabetes with semantic differential in diabetes (SDD) questionnaires. A single Likert scale (EVGFP) was used to measure self-perceived health. Participants with the combination of strong SOC and power perceived better health, experienced less burden of diabetes and had better glycaemic control than those with the combination of weak SOC and non-power. Nearly all participants with diabetes experienced problems with self-care, especially with the insulin treatment. The results highlight the importance of education that increases SOC and power as well as developing visual aids that assist blind people with diabetes in different self-care situations.
