Note: *p ≤ 0.05; **p ≤ 0.001; ***p < 0.0001; All independent variables were centered on their means. a Interaction between school type and social self-control statistically significant (p = 0.01). The reported OR is when school type = 0 (school type was centered on its mean). b Interaction between school type and social self-control statistically significant (p = 0.01). The reported OR is when social self-control = 0 (social self-control was centered on its mean). |
