本研究探讨了是否改善身体活动中发现的测试中的妈妈在移动介导的行为结构的干预是来自。确定中介变量对干预计划至关重要。该干预措施源自行为改变的跨理论模型（TTM），并促进中等强度的活动，如散步。参加妇女、婴儿和儿童项目的久坐不动的母亲（N = 44）被随机分配到实验干预组或注意力控制组。据报道，体力活动改善和TTM结构变化的效应量较大。本研究探讨了身体活动的改善是否由行为结构介导。统计分析采用双变量相关系数和两阶段多元线性回归。这些探索性的发现并不支持这样的假设，即与实验干预相关的体力活动增加是由TTM结构介导的。
This study examined whether improvements in physical activity discovered in a test of Moms on the Move were mediated by the behavioral constructs from which the intervention was derived. Identifying mediator variables is vital for intervention planning. The intervention was derived from the Transtheoretical Model (TTM) of behavior change and promoted moderately intense activities like walking. Sedentary mothers with children enrolled in the Women, Infants, and Children program (N = 44) were randomly assigned to the experimental intervention or attention control. Large effect sizes were reported for improvements in physical activity and changes in TTM constructs. This study examined whether the physical activity improvements were mediated by the behavioral constructs. Statistical analyses used bivariate correlation coefficients and two-stage multiple linear regression. These exploratory findings did not support the hypothesis that increased physical activity, which was associated with the experimental intervention, was mediated by the TTM constructs.
