This study examines the contextual and ideological dimensions of attitudes toward discretionary abortion using two national surveys. The abortion attitudes are dichotomized in terms of consistent opposition versus consistent support. Discriminant analysis, partial correlations, and stepwise regression procedures are used in the analysis. Findings indicate that education and attendance at religious services are the two most significant contextual dimensions and sexual permissiveness and fertility ideology are the two most significant ideological dimensions for explaining attitudes toward discretionary abortion. Implications of these findings are discussed.
