Because the prospective sample spans early adolescence through young adulthood and significant developmental changes are known to occur across this period, we conducted all analyses separately for the adolescent sample (ages 12–17; N = 1,192, mean = 14.48, SD = 1.76) and adult sample (ages 18–26; N = 936, mean = 19.7, SD = 1.46), as described above. This also avoided potential analytic issues associated with method variance, since some of the scales had similar but distinct versions for adolescents and young adults. The exact N available for analysis differed slightly across the measures, as the measures were completed at different points in the assessment (e.g., some in person, others through the mail); accordingly, not all participants completed the full assessment battery. All individuals with data available for a given measure were used in that particular analysis. The N values available for each analysis are indicated in the tables.
