  1. Standard errors (SE) for the means: normal weight = 0.13 – 0.24 (self) vs. 0.13 – 0.23 (parent); overweight = 0.29 – 0.53 (self) vs. 0.31 – 0.52 (parent); obese = 0.57 – 1.02 (self) vs. 0.52 – 0.86 (parent); 95% confidence intervals = mean +/- 1.96*SE)
  2. a Weight classification according to IOTF Cole et al. [26]
  3. b "d"-effect size for comparison between normal weight and obese (0.2 = small; 0.5 = medium; 0.8 = large effect)
  4. * statistical significant (p < 0.05) F-value in ANOVA; ** statistical significant (p < 0.01) F-value in ANOVA
  5. No statistically significant interaction was observed for mode * socio-economic status
  6. All statistical interactions between mode (parent versus self) and CSHCN were statistically significant
  7. All statistical interactions between mode (parent versus self) and weight status were statistically non-significant except for KINDL Psych (p = 0.011; "f" = 0.04 [marginal effect]).
