Abstract
AIM: To report results from an 18-month randomized controlled trial (RCT) testing the effectiveness of a flexible guided self-determination (GSD) intervention on glycaemic control and psychosocial distress in younger adults with poorly controlled Type 1 diabetes. METHODS:Between January 2010 and February 2012, we randomly allocated two hundred 18-35-year-olds [mean age 25.7 (5.1) years, 50% men] with Type 1 diabetes for ≥ 1 year [mean duration 13.7 (6.8) years] and HbA1c ≥ 64 mmol/mol (8.0%) to either an immediate GSD (intervention; n = 134) or 18-months delayed GSD group (control; n = 66). Group-based or individual GSD sessions were offered, drawing on reflection sheets and advanced professional communication. The primary outcome was HbA1c (measured at baseline and every three months thereafter) and among secondary outcomes was psychosocial distress (self-reported at baseline and after nine and 18 months). Intention-to-treat analyses included linear regression and repeated measurement analyses. RESULTS: A borderline significant decrease in HbA1c in the intervention group compared with the control group ( - 4 vs - 1 mmol/mol or - 0.4% vs - 0.1%; P = 0.073) was driven by a significantly greater reduction in the GSD women ( - 5 vs + 1 mmol/mol or - 0.5% vs + 0.1%; P = 0.017); parallel decreases were observed in the GSD and control men ( - 3 mmol/mol or - 0.3%; P = 0.955). Significantly greater reduction in the GSD group's psychosocial distress was again driven by differences between the GSD and the control women. The men's improvements were not connected with the intervention. CONCLUSIONS: The flexible GSD intervention benefitted younger adult women by significantly improving glycaemic control and decreasing diabetes related distress. No effect was seen among men.
