Sport is a potential venue for more middle-aged adults to engage in sufficient physical activity for health benefits. Little is known about whether messaging interventions can motivate sport activity. This experiment tested the impact of gain-framed messaging (i.e., information about the benefits of doing adult sport) based on the inclusion (or lack thereof) of efficacy-enhancing information. Adults (30-69 years-old) were randomly assigned to experimental (a 4-min online video of "Gain-framed messages alone," or "Gain-framed plus efficacy-enhancing messages") or control conditions. Participants ( = 232; 62.5% female) completed baseline measures for intentions, barrier and scheduling self-efficacy, outcomes expectancies (OEs), sport behavior and moderate-to-vigorous physical activity, received their condition 1-week later, reported measures immediately after, and 1-month later. Results showed no differences between the experimental conditions, indicating there was no advantage of supplemental efficacy-enhancing information compared to gain-framed messages alone. When the two messaging groups were collapsed, they showed significant increases for OEs related to travel, social affiliation, and stress relief immediately following experimental exposure, compared to the control group. Overall, there were few benefits attributed to messaging and no effects on self-reported sport registration or sport behavior. Discussion focuses on future messaging considerations that may more effectively motivate adult sport participation.
体育运动是一个让更多中年成年人参与足够体育活动以获得健康益处的潜在场所。关于信息干预是否能激发体育活动，人们知之甚少。本实验基于是否包含增强效能的信息，测试了获益框架信息（即关于进行成人体育运动益处的信息）的影响。成年人（30 - 69岁）被随机分配到实验组（一个4分钟的在线视频，内容为“仅获益框架信息”或“获益框架加增强效能信息”）或对照组。参与者（n = 232；62.5%为女性）完成了关于意图、障碍和计划自我效能、结果期望（OEs）、体育行为以及中度至剧烈体育活动的基线测量，1周后接受相应条件干预，干预后立即及1个月后报告测量结果。结果显示实验组之间没有差异，这表明与仅使用获益框架信息相比，补充增强效能的信息并无优势。当将两个信息组合并时，与对照组相比，在实验暴露后，他们在与旅行、社交关系和缓解压力相关的结果期望方面有显著增加。总体而言，信息干预几乎没有带来益处，对自我报告的体育注册或体育行为也没有影响。讨论聚焦于未来可能更有效地激发成人体育参与的信息干预考量。
