This qualitative study explored the intertwining relationships among the concepts of parental autonomy support, parental control, and cultural values for Mexican American families. The study was guided by the following questions: (1) What elements of parental autonomy support are identified in Mexican American parents' involvement in their children's academic performance? (2) How do Mexican American parents conceptualize "autonomy support" and "parental control"? Sixteen Mexican American mothers expressed their own goals and strategies for home-based parental involvement to support their adolescents' academic performance, and responded to the prototypes of autonomy support parenting and use of psychological control. Four themes emerged from the data to explain the participants' practice: (1) Explain the expectations for behavioral and academic pursuit through persistent "telling" and "reminding"; (2) Respond to children's feelings from parents' perspectives; (3) Encourage with provisions, praises, and criticisms; and (4) Allow choices upon trust in child's sense of responsibility. Discussion is focused on how Mexican-American mothers' conceptualization of "autonomy support" and "parental control" is influenced by the cultural values of educación and respeto. Culturally appropriate autonomy support training is suggested for effective intervention programs for Mexican-American parents.
