The present study explored the facilitating function of religious commitment in the lives of adolescents. A total of 369 boys and 372 girls attending catholic high schools in canada completed measures of family religion, religiosity, prosocial values, social adjustment (school attitudes and family satisfaction), and personal adjustment (life satisfaction and self-esteem). There were no significant gender differences in family religion, religiosity, social adjustment or personal adjustment. However, girls endorsed prosocial values much more than did boys. Religiosity had strong positive correlations with prosocial values and lesser significant correlations with social adjustment. Religiosity had much higher correlations with prosocial values and social adjustment among boys than among girls. Structural-equation analyses of the total sample, of boys, and of girls supported a path model where family religion fosters adolescents’s religiosity, religiosity fosters prosocial values, prosocial values promote social adjustment and social adjustment promotes personal adjustment. 2000, Taylor & francis group, llc.
