*Assessed in part 2 sample due to having part 2 controls. Controls for the model include intervals (1–5 intervals), and also include significant variables from demographic and parent psychopathology models, details in the following footnotes.
†Model controls for intervals (1–5 intervals), demographics (sex, age, time-varying education), interaction between intervals (13–19, 20–29, 30+) and age, education. For parent psychopathology, controlling for number of parental disorders (dummies for 1, 2+ disorders).
‡Model controls for intervals (1–5 intervals), demographics (sex, age, time-varying education), interaction between intervals (13–19, 20–29, 30+) and age, education. For parent psychopathology, controlling for types of parental disorders (6 dummies).
§Model controls for intervals (1–5 intervals), demographics (sex, age, time-varying education), interaction between intervals (13–19, 20–29, 30+) and age, education. Parent psychopathology not controlled for due to insignificance in previous models.
¶Significant at the 0.05 level, two-sided test.
