Notes: n = 866 for adolescents; n = 668 for mothers. 95% confidence intervals are reported in brackets. Means in a row with the same superscript are not significantly different at the level of p < 0.05 (Tamhane’s T2 adjustment was used because the variances were not equal across the groups).
*** p < 0.001.
