计划行为理论(TPB)的研究发现，感知行为控制(PBC)是步行意图的关键决定因素。本研究调查了旨在改变PBC和制定步行计划的干预措施是否增加了关于更多步行、规划和客观测量步行的TPB措施。130名英国成年人参加了一项等待名单的随机对照试验。干预包括促进PBC的策略，以及制定步行意图的意志策略。所有的TPB结构都被测量了，以及自我报告的行动计划和步行的测量，以及行走时间的客观计步器测量。干预增加了PBC、态度、意图和客观测量步行时间，从每天20分钟增加到32分钟。干预对意图和行为的影响是由PBC中介的，而对PBC的影响不是通过控制信念来调节的。在6周的随访中，参与者保持了步行的增加。这项研究的结果部分支持了扩展的TPB作为制定和评估健康行为改变干预措施的框架的拟议因果性质。这是第一项使用TPB来开发、设计和评估干预组件的研究，该组件增加了客观测量的行为，影响由TPB变量调节。
Theory of planned behaviour (TPB) studies have identified perceived behavioural control (PBC) as the key determinant of walking intentions. The present study investigated whether an intervention designed to alter PBC and create walking plans increased TPB measures concerning walking more, planning and objectively measured walking. One hundred and thirty UK adults participated in a waiting-list randomised controlled trial. The intervention consisted of strategies to boost PBC, plus volitional strategies to enact walking intentions. All TPB constructs were measured, along with self-reported measures of action planning and walking, and an objective pedometer measure of time spent walking. The intervention increased PBC, attitudes, intentions and objectively measured walking from 20 to 32 min a day. The effects of the intervention on intentions and behaviour were mediated by PBC, although the effects on PBC were not mediated by control beliefs. At 6 weeks follow-up, participants maintained their increases in walking. The findings of this study partially support the proposed causal nature of the extended TPB as a framework for developing and evaluating health behaviour change interventions. This is the first study using the TPB to develop, design and evaluate the components of an intervention which increased objectively measured behaviour, with effects mediated by TPB variables.
