PRIMARY outcome

Timeframe: Up to 5 time points during the intervention (12 months) and up to 4 time points in the post-intervention period (12 months)

Population: 214 participants were analyzed for up to 5 time points during the intervention and up to 4 time points in the post-intervention period. Models include data to the point of withdrawal for 3 families.

Mean change in A1c per month (slope), during and post-intervention.

PRIMARY outcome

Timeframe: Up to 2 time points during the intervention (12 months) and up to 3 time points in the post-intervention period (12 months)

Population: 214 participants were analyzed for up to 2 time points during the intervention and up to 3 time points in the post-intervention period. Models include data to the point of withdrawal for 3 families.

Mean change in child quality of life per month (slope), during and post-intervention. Child quality of life is measured by the PedsQL Diabetes Module. Possible scores range from 0 to 100 with higher scores indicating better quality of life. Positive slopes reflect improving quality of life.

PRIMARY outcome

Timeframe: Up to 2 time points during the intervention (12 months) and up to 3 time points in the post-intervention period (12 months)

Population: 214 parents were analyzed for up to 2 time points during the intervention and up to 3 time points in the post-intervention period. Models include data to the point of withdrawal for 3 families.

Mean change in parent quality of life per month (slope), during and post-intervention. Parent quality of life is measured by the PedsQL Family Impact Module. Possible scores range from 0 to 100 with higher scores indicating better quality of life. Positive slopes reflect improving quality of life.

SECONDARY outcome

Timeframe: Up to 2 time points during the intervention (12 months) and up to 2 time points in the post-intervention period (12 months)

Population: 214 parents were analyzed for up to 2 time points during the intervention and up to 2 time points in the post-intervention period. Models include data to the point of withdrawal for 3 families.

Mean change in parent fear of hypoglycemia per month (slope), during and post-intervention. Parent fear of hypoglycemia is measured by the Hypoglycemia Fear Survey Worry Subscale. Possible scores range from 15 to 75 with higher scores indicating greater fear of hypoglycemia. Positive slopes reflect increasing fear of hypoglycemia.
