a
Non-completers (n = 7) tended to be older (M = 15.54 years vs 17.06 years) and have higher YTP scores at baseline (M = 8.40 vs 7.18), but did not differ significantly (p > 0.05) from intervention completers on the basis of sex or SDQ scores.
b
Non-completers (n = 10) did not differ significantly (p > 0.05) from intervention completers on the basis of age, sex or baseline scores.
