While behavior change techniques (BCTs) support physical activity (PA) behavior change, further examination aimed at understanding their enactment is needed.
This study aimed to examine the daily enactment of BCTs and the factors that impact their daily usage.
Using experience sampling methods, we sampled 53 university students (Mage = 22 years; SDage = 3.93 years) from McGill (n = 40) and Queen's (n = 13) University to examine BCT usage among university students with physical disabilities and chronic conditions. A daily online survey was delivered for 10 consecutive days where participants answered a checklist of 28 BCTs, a modified 6-item Capability, Opportunity, and Motivation (COM) questionnaire and questions on situational disruptions. Descriptive analysis summarized BCT usage, COM, and contextual factors. A generalized linear mixed model examined the relationship between demographic variables, COM, and contextual factors on the usage of BCTs.
On average, participants used 11 BCTs daily, while 22 distinct BCTs were used over the 10 days. The most frequently used BCTs were task crafting and goal integration. The least used BCTs included self-monitoring and obtaining information on how to perform PA. Women were more likely than men to enact certain BCTs, while students with physical disabilities were less likely than those with chronic conditions to enact others. Participants reported higher daily capability and opportunity to use BCTs compared to motivation. Situational disruptions such as personal commitments (eg, work) followed by flare-ups (eg, pain) were frequently reported. Motivation and opportunity predicted the usage of 15 to 24 BCTs, while capability predicted the usage of 2 BCTs.
Our findings provide valuable context on BCT enactment, thereby improving the structure of future PA behavior change interventions.
虽然行为改变技术（BCTs）有助于身体活动（PA）行为的改变，但仍需进一步研究以了解其实施情况。
本研究旨在考察BCTs的日常实施情况以及影响其日常使用的因素。
采用经验抽样法，我们从麦吉尔大学（n = 40）和女王大学（n = 13）抽取了53名大学生（平均年龄 = 22岁；标准差年龄 = 3.93岁），以考察身体残疾和患有慢性病的大学生对BCTs的使用情况。连续10天进行每日在线调查，参与者需回答一份包含28种BCTs的清单、一份修改后的6项能力、机会和动机（COM）问卷以及关于情境干扰的问题。描述性分析总结了BCTs的使用情况、COM以及情境因素。广义线性混合模型考察了人口统计学变量、COM和情境因素与BCTs使用之间的关系。
参与者平均每天使用11种BCTs，在这10天内共使用了22种不同的BCTs。最常使用的BCTs是任务设计和目标整合。最少使用的BCTs包括自我监测以及获取有关如何进行身体活动的信息。女性比男性更有可能实施某些BCTs，而身体残疾的学生比患有慢性病的学生实施其他BCTs的可能性更小。参与者报告称，与动机相比，他们每天使用BCTs的能力和机会更高。经常报告的情境干扰包括个人事务（如工作），其次是突发状况（如疼痛）。动机和机会预测了15至24种BCTs的使用情况，而能力预测了2种BCTs的使用情况。
我们的研究结果为BCTs的实施提供了有价值的背景信息，从而改进了未来身体活动行为改变干预措施的结构。
