This study used ecological momentary assessment (EMA), a real-time self-report strategy, to examine (1) whether dog owners were more likely to be physically active when they were with their dogs and (2) whether being with a dog amplifies positive and dampens negative affective response during physical activity.
Electronic EMA surveys for 12 days.
Free-living.
Seventy-one adult dog owners.
The EMA survey included 1 question about current activity, 3 questions about positive affect (Cronbach α = .837), 4 questions about negative affect (Cronbach α = .865), and 1 question about the presence of dog.
Multilevel modeling.
The company of a dog did not increase the likelihood of being active versus sedentary at any given EMA prompt. However, greater positive affect during physical activity was reported in the company of a dog. Negative affect did not differ between active and sedentary activity, regardless of being with a dog or not.
This study demonstrates the utility of electronic EMA as a promising methodology to study dog-accompanied physical activity. Future studies may use EMA to collect further contextual information about dog-accompanied activity to inform the development of innovative physical activity interventions.
本研究采用生态瞬时评估（EMA）这一实时自我报告策略，以检验：（1）狗主人与狗在一起时是否更有可能进行身体活动；（2）在身体活动期间，与狗在一起是否会增强积极情绪并减轻消极情绪反应。
为期12天的电子EMA调查。
自由生活环境。
71名成年狗主人。
EMA调查包括1个关于当前活动的问题、3个关于积极情绪的问题（克朗巴赫α系数 = 0.837）、4个关于消极情绪的问题（克朗巴赫α系数 = 0.865）以及1个关于是否有狗陪伴的问题。
多水平建模。
在任何给定的EMA提示下，有狗陪伴与久坐相比，并没有增加活动的可能性。然而，在有狗陪伴时进行身体活动会报告有更大的积极情绪。无论是否有狗陪伴，积极活动和久坐活动期间的消极情绪没有差异。
本研究证明了电子EMA作为一种有前景的方法来研究狗陪伴下的身体活动的实用性。未来的研究可以使用EMA来收集关于狗陪伴活动的更多背景信息以指导创新身体活动干预措施的开发。
