  1. a All variables are based on maternal reports except the child-rated CSI and the school record information on absences.
  2. b Values are numbers (percentage, calculated from total column) except when noted.
  3. c The final multivariable model was obtained following a stepwise backwards likelihood-ratio elimination procedure.
  4. d Continuous variables were standardized in logistic regression models so that the ORs may be interpreted as the odds of participation for a one standard deviation increase in the predictor.
