This study coordinates moral value development in adolescence, parenting style, and gender with issues of stability and specificity. The primary research question asked whether parenting styles of mothers and fathers influence the development of adolescent moral values, and secondary research questions asked whether adolescent moral values were stable and whether gender moderated predictive relations of parenting styles and adolescent moral values. At 14 and 18 years, a sample of 246 adolescents completed the Sociomoral Reflection Objective Measure -- Short Form; at 14 years, mothers and fathers self-reported their parenting styles using the Parental Authority Questionnaire. Exploratory and confirmatory factor analyses established a 2-factor model of adolescent moral values across the two ages: Life and Social Contract captured prosocial aspects of morality that are left to individual choice, and Law and Social Order captured acts that are legally or morally obligatory for individuals to perform. Structural equation modeling investigated relations between parental parenting styles and the two adolescent moral value factors, with adolescent age, gender, and family SES as covariates. Both moral values factors had high stabilities across the 4-year period. Mothers' authoritarian parenting at 14 years, but not their authoritative or permissive parenting, negatively predicted Life and Social Contract moral values, but not Law and Social Order, in adolescents at 18 years, more so for boys. Fathers' parenting styles did not predict adolescents' moral values at 18 years. Girls and adolescents from higher-SES families had higher Life and Social Contract moral values at 14 years; boys experienced more increases in Life and Social Contract moral values from 14 to 18 years than girls. Stability and parental predictive validity of moral values for adolescence are discussed.
