| Depressive Symptoms | 0.70* | 0.06 | 0.74 (Medium) |
| Prospective Episodes | |||
| Rumination | 0.67* (unique predictor) | 0.03 | 0.62 (Medium) |

| Attributional Style | 0.64* (unique predictor) | 0.03 | 0.51 (Medium) |
| Depressive Symptoms | 0.63* (unique predictor) | 0.03 | 0.47 (Medium) |
| FLED | |||
| Rumination | 0.63* (unique predictor) | 0.03 | 0.47 (Medium) |

| Depressive Symptoms | 0.56 | 0.06 | 0.21 (Small) |
| rMDD | |||
| Rumination | 0.69* (unique for 6th grade only) | 0.03 | 0.70 (Medium) |
| Dysfunctional Attitudes | 0.63* | 0.04 | 0.47 (Medium) |
| Attributional Style | |||
| (6th grade/9th grade) | 0.54/0.67* (unique predictor) | 0.06/0.05 | 0.14/0.62 (Medium) |
| Depressive Symptoms | 0.66* (unique predictor) | 0.04 | 0.58 (Medium) |
Note: For rumination forecasting rMDD, the AUC reflects the curve for the total sample but is only a unique predictor in the sixth grade. AUC = area under the curve; SE = standard error for AUC; Cohen’s d = effect size; Small, Medium, and Large = effect size for predictor (Rice & Harris, 2005); Concurrent episodes = meeting criteria for an episode of depression at baseline; Prospective episodes = meeting criteria for an episode of depression during the follow-up period; FLED = first lifetime episode of depression (i.e., episode of depression during 36 months with no lifetime history); rMDD = recurrent major depression disorder (i.e., more than one episode of depression over the lifetime); Rumination = total score on the Children’s Response Style Questionnaire–Rumination subscale (Abela et al., 2004); Dysfunctional attitudes = total score on the Children’s Dysfunctional Attitude Scale (Abela & Sullivan, 2003); Attributional style = total score on the Adolescent Cognitive Style Questionnaire (Hankin & Abramson, 2002); Depressive symptoms = total score on the Children’s Depression Inventory (Kovacs, 1992); Unique predictor = whether the residuals were significant once covarying out other significant predictors for that criterion (first depressive symptoms, and then other significant predictors).
