The stability of quality of life experience in people with type 1 diabetes over a period of a year.

The aim of the present study was to examine the stability of self-reported quality of life experience over a period of 1 year using a standard measure consisting of 29 items measuring satisfaction in the physical, social, psychological and behavioural/activity life domains and 11 well-being scales. One hundred and six people with Type 1 diabetes attending a Norwegian diabetes clinic participated in the study. At first and second assessment, questionnaires were administered and completed at the diabetes clinic. Regression coefficients for the linear relationship between the assessments were relatively high indicating stability in reported quality of life experience over a period of 1 year. Comparisons between subjects experiencing life events relating to personal and/or family problems during the 12-month period and those not showed that, in addition to stability coefficients being relatively high for both groups, the majority of the stability coefficients for the group reporting life events were not significantly different from the stability for the group reporting no life events.
