Determine the use of the processes of change (POC) across the exercise stages of change and across varying intensities and frequencies of exercise behavior.
Cross-sectional design.
University setting.
Questionnaires were collected from 699 college-aged individuals.
Data were collected for exercise stages of change, POC and exercise behavior. Self-report exercise data were categorized as 0 days, 1 to 2 days, and 3 or more days per week of moderate and vigorous exercise.
MANOVA assessed differences in the use of the 10 POC across the stages of change and across varying frequencies of moderate and vigorous exercise behavior.
Results showed all 10 POC were significant between the exercise stages of change and differing frequencies of moderate and vigorous exercise behavior. Post hoc analysis identified 7 significant processes between adjacent exercise stages of change, 10 significant processes between differing frequencies of moderate exercise behavior, and 9 significant processes between differing frequencies of vigorous exercise behavior.
The results for this study suggest that intensity and frequency may be factors in the use of the POC. The use of the POC showed a linear increase across stage, which deviates from the proposed Transtheoretical Model framework and previous research. Additional investigation into the processes and stages of change, and their role in changing exercise behavior is needed.
确定在运动行为改变的各个阶段以及不同运动强度和频率下改变过程(POC)的使用情况。
横断面设计。
大学环境。
收集了699名大学生的问卷。
收集运动行为改变阶段、POC和运动行为的数据。自我报告的运动数据分为每周0天、1至2天以及3天或更多天的中等强度和剧烈运动。
多变量方差分析评估了在运动行为改变阶段以及不同频率的中等强度和剧烈运动行为中10种POC使用情况的差异。
结果表明,在运动行为改变阶段以及不同频率的中等强度和剧烈运动行为之间,所有10种POC均具有显著性差异。事后分析确定了相邻运动行为改变阶段之间有7个显著过程,不同频率的中等强度运动行为之间有10个显著过程,不同频率的剧烈运动行为之间有9个显著过程。
本研究结果表明,强度和频率可能是POC使用的影响因素。POC的使用在各阶段呈线性增加,这与提出的跨理论模型框架及先前研究有所不同。需要对改变过程和阶段及其在改变运动行为中的作用进行进一步研究。
