  1. All mixed models were adjusted for school, year, gender, age (and K6 scores for Quality of first aid provided to/received from a peer). Boldface indicates statistical significance
  2. aFor John vignette depicting peer with symptoms of depression & suicide risk n = 791; for Jeanie vignette depicting peer with symptoms of social anxiety n = 769
  3. bFor John vignette n = 807; for Jeanie vignette n = 792
  4. cFor John vignette n = 429; for Jeanie vignette n = 409
  5. dFor John vignette n = 465; for Jeanie vignette n = 446
  6. eLarge effect size Cohen’s d = 0.8, medium effect size d = 0.5, small effect size d = 0.2
  7. fPeriod-cluster intraclass correlation coefficients (ICC) indicate the proportion of variability in the outcome attributable across clusters
  8. gThis measure was the primary outcome
  9. hScores were non-normally distributed (rarely endorsed), so were dichotomised at 0/1–6; values shown are % scoring 1 or above and mixed effects logistic regression models
  10. iIncludes those who reported offering help at either timepoint; n = 483 at baseline, n = 136 at follow-up, n = 215 at both points, n = 834 total
  11. jScores were non-normally distributed with heavy skew (rarely endorsed), so were dichotomised at 0/1–6; values shown are % scoring 1 or above and mixed effects logistic regression models based on scores from n = 834
  12. kIncludes only those who reported experiencing a mental health problem at baseline and 12 m follow-up and receiving help from a peer; n = 309
  13. lScores were non-normally distributed with heavy skew (rarely endorsed), so were dichotomised at 0/1–6; values shown are % scoring 1 or above and mixed effects logistic regression models based on scores from n = 309
