CI, confidence interval; OR, odds ratio; VEM, variable excluded from the model; VPI, variable is part of an interaction. a The reference group is that of children without internalizing or externalizing problems. b In the last 12 months. c Interaction terms included in regression models: model I [(1)*(3), (1)*(5), (1)*(11)]; model II: [(9)*(2), (3)*(7)]; and model III [(1)*(2) and (3)*(7)].
