Aim To determine the potential effect sizes for the Flexible Lifestyle for Youth (FL3X) behavioural intervention to improve glycaemic control (HbA1c) and quality of life for at‐risk adolescents with Type 1 diabetes. Methods Participants [n = 61; age 12–16 years, HbA1c 64–119 mmol/mol (8–13%)] were randomized to FL3X (minimum three sessions) or usual care. Effect sizes (Cohen's d), comparing the mean difference between the groups, were calculated. Results Study retention (95%), attendance at intervention sessions (87% attended all three sessions) and acceptability were high (100% of the adolescents and 91% of parents would recommend the programme to others). Overall, 41% of participants in the intervention group and 24% of participants in the control group were ‘responders’ [HbA1c decreased by  >  6 mmol/mol (0.5%); d = 0.37]. HbA1c levels decreased (d = ‐0.18), diabetes‐specific quality of life increased (d = 0.29), but generic quality of life decreased (d = ‐0.23) in the intervention compared with the control group. Conclusions The FL3X programme merits further study for improving HbA1c and diabetes‐specific quality of life in adolescents with Type 1 diabetes. (Clinical trials registry no.: NCT01286350). What's new? Flexible Lifestyles for Youth (FL3X), is a new behavioural intervention that combines motivational interviewing, problem‐solving skills, family communication and teamwork. The FL3X programme could improve metabolic status and quality of life for adolescents with Type 1 diabetes.
