Table 1.
Mean relative reinforcing efficacy, mean delay discounting, mean sibling differences, and intraclass correlations (with 95% CIs) by sibling weight status. Sibling difference is calculated by subtracting the raw data of the non-overweight sibling from the overweight sibling.
Non-overweight sibling | Overweight sibling | Sibling difference | ICC | |
---|---|---|---|---|
Relative reinforcing efficacy (breakpoint, $USD) | 5.3 ± 1.1 | 8.3 ± 2.3 | 3.0 ± 1.4 | 0.29 (–0.24, 0.69) |
Delay discounting (AUC) | 0.15 ± 0.02 | 0.13 ± 0.02 | 0.01 ± 0.03 | –0.02 (–0.52, 0.49) |
Data are mean ± SE.
AUC – area under the curve.
