  1. IRR, Incidence rate ratio.
  2. Analysis adjusted by sex, race/ethnicity, parental income at Wave I, age at Wave V, depression score (5-item depression scale) at Wave V, and alcohol consumption at Wave V.
  3. * Interpret “meeting all three” results with caution given low frequency of individuals in “meets at adolescence and adulthood” category and suicidal ideation (1.2%).
