Dichotomous measure. All other characteristics for which no reference category is shown are continuous or scaled.
Divided by age and standardized. Notes: Gender interactions with each independent variable were tested; none of the interaction terms was associated with positive pregnancy attitudes. For nonuse of effective method, gender had a significant interaction with Hispanic ethnicity (p=.03) and a marginally significant interaction with number of network members who attend school (p=.07). The interaction between gender and Hispanic ethnicity was not included because the associations were not significant in the full sample or for either gender.
ref=reference group. na=not applicable, because item was not included in the analysis.
