p < .001. Analyses were conducted in which the intercept as set at the 10^th grade (early), 12^th grade (mid) and 5 to 6 years after high school (late). A positive beta for an intercept indicates that later debut is associated with higher scores at that point, and a positive beta for a slope indicates that later debut is associated with an increase in scores over time.
