Effects were evaluated using the null hypothesis test of b = 0 (tested as: b/SE) which evaluates the unique contribution of a variable in a regression equation. a High school and college drinking were defined as the number of drinks per drinking day during the past year. b Religiosity was dichotomized into a binary variable (i.e., extremely/moderately vs. slightly/not important). c As a proxy for socioeconomic status, the effect of mother's education was held constant in the multivariate models. |
