Most people with type 2 diabetes do not engage in regular leisure-time physical activity. The theory of planned behavior and moral norm construct can enhance our understanding of physical activity intention and behavior among this population.
This study aims to identify the determinants of both intention and behavior to participate in regular leisure-time physical activity among individuals with type 2 diabetes who not meet Canada's physical activity guidelines.
By using secondary data analysis of a randomized computer-tailored print-based intervention, participants (n = 200) from the province of Quebec (Canada) completed and returned a baseline questionnaire measuring their attitude, perceived behavioral control, and moral norm. One month later, they self-reported their level of leisure-time physical activity.
A hierarchical regression equation showed that attitude (beta = 0.10, P < 0.05), perceived behavioral control (beta = 0.37, P < 0.001), and moral norm (beta = 0.45, P < 0.001) were significant determinants of intention, with the final model explaining 63% of the variance. In terms of behavioral prediction, intention (beta = 0.34, P < 0.001) and perceived behavioral control (beta = 0.16, P < 0.05) added 17% to the variance, after controlling the effects of the experimental condition (R (2) = 0.04, P < 0.05) and past participation in leisure-time physical activity (R (2) = 0.22, P < 0.001). The final model explained 43% of the behavioral variance. Finally, the bootstrapping procedure indicated that the influence of moral norm on behavior was mediated by intention and perceived behavioral control.
The determinants investigated offered an excellent starting point for designing appropriate counseling messages to promote leisure-time physical activity among individuals with type 2 diabetes.
大多数2型糖尿病患者未进行规律的休闲体育活动。计划行为理论和道德规范构建能够增进我们对该人群体育活动意向和行为的理解。
本研究旨在确定未达加拿大体育活动指南的2型糖尿病患者参与规律休闲体育活动的意向和行为的决定因素。
通过对一项随机计算机定制印刷干预进行二次数据分析，来自加拿大魁北克省的参与者（n = 200）完成并返还了一份测量其态度、感知行为控制和道德规范的基线问卷。一个月后，他们自我报告了休闲体育活动水平。
分层回归方程显示，态度（β = 0.10，P < 0.05）、感知行为控制（β = 0.37，P < 0.001）和道德规范（β = 0.45，P < 0.001）是意向的显著决定因素，最终模型解释了63%的方差。在行为预测方面，在控制了实验条件的影响（R（2）= 0.04，P < 0.05）和过去参与休闲体育活动的影响（R（2）= 0.22，P < 0.001）后，意向（β = 0.34，P < 0.001）和感知行为控制（β = 0.16，P < 0.05）使方差增加了17%。最终模型解释了43%的行为方差。最后，自抽样程序表明，道德规范对行为的影响是通过意向和感知行为控制介导的。
所研究的决定因素为设计合适的咨询信息以促进2型糖尿病患者的休闲体育活动提供了一个良好的起点。
