The moderating effect of exercise habit strength and specific habit processes within the theory of planned behavior (TPB) was tested in children.
Participants were primary school students (N = 380, mean age = 10.46 ± .52). The data were collected using self-report measures followed by one-mile run test performance. Data were analyzed using structural equation modeling.
The findings revealed that 34, 57, and 9% of students could be classified as low, moderate, and high in PA, respectively. Path analysis for the overall model revealed significant path loadings (p = < .05), except for the attitude-intention path. Moderating effects results revealed that strong habit strength extinguished the effects of intention on PA.
Habit strength has the potential to minimize the deliberate processes associated with intention to exercise, thereby increasing the probability of intention-behavior translation. For specific habit processes, only negative affect appears to moderate the relationships between the TPB variables.
在儿童中测试运动习惯强度和计划行为理论（TPB）中特定习惯过程的调节作用。
参与者为小学生（N = 380，平均年龄 = 10.46 ± 0.52）。数据通过自我报告测量收集，随后进行一英里跑步测试表现。使用结构方程模型分析数据。
研究结果显示，分别有34%、57%和9%的学生在身体活动方面可被归类为低、中、高。整体模型的路径分析显示，除态度-意图路径外，路径负荷显著（p < 0.05）。调节作用结果显示，强烈的习惯强度消除了意图对身体活动的影响。
习惯强度有可能将与运动意图相关的刻意过程降至最低，从而增加意图-行为转化的可能性。对于特定的习惯过程，只有负面影响似乎调节了TPB变量之间的关系。
