Longitudinal Mixed Models of Three-Factor Eating Questionnaire Scores in Relation to BMI Percent of 95th Percentile

Model Components	Overall	LC	RGL	PC
Disinhibition score	Ns	ns	ns	ns
Hunger score	0.31 ± 0.10*	ns	ns	0.62 ± 0.17*
Restraint score	−0.51 ± 0.14*	−0.72 ± 0.23*	−0.46 ± 0.09*	ns
Restraint by visit interactiona	p = 0.006	p = 0.0003	ns	ns
Restraint: baseline	0.59 ± 0.23*	1.0 ± 0.41**
Restraint: 3 months	0.53 ± 0.16*	0.88 ± 0.24*
Restraint: 6 months	0.29 ± 0.13**	0.43 ± 0.24
Restraint: 12 months	0 (Ref.)	0 (Ref.)

All models adjust for visit, age, sex, and race. The overall model also adjusts for diet group assignment.

^aInterpretation note regarding interaction: to obtain overall estimates of the effect of restraint score by visit, the restraint offset at that visit should be added to the restraint main effect; for example, estimate for restraint at baseline = −0.51 + 0.59 = 0.08 BMI percent of 95th percentile. p-Values in this section indicate whether each visit's offset differs significantly from the restraint estimate at 12 months (reference visit).
