Note: TX = treatment group, Headstrong; CTRL = educational control group; n = number of participants; ES = Effect size (Cohen's d) for difference between independent means. A value of 0.5 or greater indicates a medium effect size and 0.8 or greater a large effect size; p = 1-tail significance of the difference between the two means directly above it. A value of < 0.05 indicates a significant difference in means.
