Hierarchical linear regression predicting adolescents’ HbA1c from measures of adherence.

Predictor	β	R^2	ΔR^2
Step 1		0.03	0.03
Adolescents’ sex	−0.13
Treatment type	0.05
Adolescents’ age	0.07
Step 2		0.22	0.20
Adolescents’ sex	−0.15
Treatment type	0.03
Adolescents’ age	−0.03
BGM	−0.18
Adolescents’ SCI	−0.33
Caregivers’ SCI	−0.08

Note. BGM = blood glucose monitoring (average checks per day); SCI = self-care inventory. The model value is adjusted R². β = standardized beta. . .
