↵* Unless otherwise indicated.
↵† Stressful life events reported in the previous survey cycle 2 yr earlier (e.g., ages 10–11 yr for those aged 12–13 yr at baseline).
↵‡ Reported at previous assessment 2 yr earlier (e.g., ages 12–13 yr for those aged 14–15 yr at baseline). These measures were not assessed prior to age 12; thus, no data are available for those aged 12–13 yr at baseline.
↵§ Previous suicide attempts were only assessed in the subset of respondents with baseline information from cycles 4–7 (not 3–7) because of availability of the assessment.
