Aims: To determine the effects of an empowerment programme on glycaemic control and empowerment, and to study the role of parental involvement.
Methods: The wait-list design is a randomized controlled trial lasting for 6 months, after which the control group participate in the same education programme as the intervention group. After 6 months, data from the two groups are analysed together (pre/post). Thirty-two teenagers with Type 1 diabetes (12-17 years) completed an empowerment group education programme, meeting weekly for 6 weeks. They were also offered an extra meeting together with their parents, which resulted in three groups: together with parents, only parents and no parent involvement at all. HbA(1c) was measured before intervention and after 6, 12, 18 and 24 months, and empowerment before, and 6 and 12 months after.
Results: HbA(1c) and empowerment were similar in the intervention group and the control group 6 months after intervention. In pre/post analysis, HbA(1c) was significantly higher 6 and 12 months after intervention in teenagers > 14 years (from 8.4% to 9.3%; P < 0.05 to 9.6%; P < 0.01), but returned to baseline 18 months after the programme. In teenagers < or = 14 years of age, HbA(1c) did not change during the study. The teenagers felt more ready for changes after the programme than before (3.9 sd = 0.5 to 4.1 sd = 0.5; P < 0.05). In the teenagers in the group that involved their parents, there was a significant decrease in HbA(1c) 12 and 24 months after intervention, from 8.9% (sd = 1.1) to 7.6% (sd = 1.3; P < 0.05, confidence interval 0.37, 2.26).
Conclusion: This empowerment programme for teenagers with diabetes showed no positive glycaemic or empowerment effects. Empowerment programmes for diabetic teenagers in early and middle adolescence should include parental involvement.
