移动设备是为改善关键的日常健康行为提供及时指导和支持的有希望的渠道。尽管针对身体活动和其他健康行为的手机应用程序激增，但很少有基于理论推导的结构和经验证据的应用程序。80名年龄在45岁及以上、身体活动不足、每天长时间坐着、不熟悉智能手机技术的成年人，参与了基于行为科学理论和证据得出的动机框架的三种日常活动智能手机应用程序的迭代设计开发和可行性测试。一个“分析式”框架定制应用程序，专注于个性化目标设置、自我监控和主动解决行为改变障碍的问题。一个“社会”框架的定制应用程序，侧重于社会比较、规范和支持。这是一款基于“情感”框架的定制应用，侧重于强化调度的操作性条件反射原则和对化身的情感转移，其动作和行为反映了用户的身体活动和久坐水平。为了探索应用程序在改变常规身体活动和休闲时间坐着的初始功效，使用CHAMPS身体活动问卷和澳大利亚久坐行为问卷对68名参与者进行了为期8周的行为变化评估。通过干预后的用户调查来探索用户对应用程序的可接受性和满意度。结果表明，在为期8周的行为采用期内，这三种应用程序足以显著改善常规中至高强度的身体活动和减少休闲时间坐着。这些应用程序的可接受性在干预后的调查中得到了证实，调查对象是新接触智能手机技术的中年和老年人。在较长时间内探索应用程序持续使用的初步数据产生了有希望的结果。该结果支持进一步系统调查应用程序对改变这些关键的健康促进行为的功效。
Mobile devices are a promising channel for delivering just-in-time guidance and support for improving key daily health behaviors. Despite an explosion of mobile phone applications aimed at physical activity and other health behaviors, few have been based on theoretically derived constructs and empirical evidence. Eighty adults ages 45 years and older who were insufficiently physically active, engaged in prolonged daily sitting, and were new to smartphone technology, participated in iterative design development and feasibility testing of three daily activity smartphone applications based on motivational frames drawn from behavioral science theory and evidence. An “analytically” framed custom application focused on personalized goal setting, self-monitoring, and active problem solving around barriers to behavior change. A “socially” framed custom application focused on social comparisons, norms, and support. An “affectively” framed custom application focused on operant conditioning principles of reinforcement scheduling and emotional transference to an avatar, whose movements and behaviors reflected the physical activity and sedentary levels of the user. To explore the applications' initial efficacy in changing regular physical activity and leisure-time sitting, behavioral changes were assessed across eight weeks in 68 participants using the CHAMPS physical activity questionnaire and the Australian sedentary behavior questionnaire. User acceptability of and satisfaction with the applications was explored via a post-intervention user survey. The results indicated that the three applications were sufficiently robust to significantly improve regular moderate-to-vigorous intensity physical activity and decrease leisure-time sitting during the 8-week behavioral adoption period. Acceptability of the applications was confirmed in the post-intervention surveys for this sample of midlife and older adults new to smartphone technology. Preliminary data exploring sustained use of the applications across a longer time period yielded promising results. The results support further systematic investigation of the efficacy of the applications for changing these key health-promoting behaviors.
