ABSTRACT: This study explored changes in parents’beliefs about the origin of control for behavior and its consequences after completion of Lamaze classes, Red Cross classes, and no classes. Results indicate that Lamaze training for women, led to a significant increase in new mothers seeing themselves as origins of control (as against seeing others or chance as agents of control). Other modes showed no significant change for women. No significant postpartum findings emerged for men under any condition. These findings are discussed and suggestions are made for modification of Lamaze training to improve it and to better meet the immediate needs of expectant and new parents.
