Smart Walk is a culturally relevant, social cognitive theory-based, smartphone-delivered intervention designed to increase physical activity (PA) and reduce cardiometabolic disease risk among African American (AA) women.
This study aimed to describe the development and initial usability testing results of Smart Walk.
Smart Walk was developed in 5 phases. Phases 1 to 3 focused on initial intervention development, phase 4 involved usability testing, and phase 5 included intervention refinement based on usability testing results. In phase 1, a series of 9 focus groups with 25 AA women (mean age 38.5 years, SD 7.8; mean BMI 39.4 kg/m2, SD 7.3) was used to identify cultural factors associated with PA and ascertain how constructs of social cognitive theory can be leveraged in the design of a PA intervention. Phase 2 included the analysis of phase 1 qualitative data and development of the structured PA intervention. Phase 3 focused on the technical development of the smartphone app used to deliver the intervention. Phase 4 consisted of a 1-month usability trial of Smart Walk (n=12 women; mean age 35.0 years, SD 8.5; mean BMI 40 kg/m2, SD 5.0). Phase 5 included refinement of the intervention based on the usability trial results.
The 5-phase process resulted in the development of the Smart Walk smartphone-delivered PA intervention. This PA intervention was designed to target social cognitive theory constructs of behavioral capability, outcome expectations, social support, self-efficacy, and self-regulation and address deep structure sociocultural characteristics of collectivism, racial pride, and body appearance preferences of AA women. Key features of the smartphone app included (1) personal profile pages, (2) multimedia PA promotion modules (ie, electronic text and videos), (3) discussion boards, and (4) a PA self-monitoring tool. Participants also received 3 PA promotion text messages each week.
The development process of Smart Walk was designed to maximize the usability, cultural relevance, and impact of the smartphone-delivered PA intervention.
Smart Walk 是一种基于文化相关性、社会认知理论的智能手机干预措施,旨在增加非裔美国女性(AA)的身体活动(PA)并降低心血管代谢疾病风险。
本研究旨在描述 Smart Walk 的开发和初步可用性测试结果。
Smart Walk 分 5 个阶段开发。第 1 至 3 阶段专注于初始干预措施的开发,第 4 阶段涉及可用性测试,第 5 阶段包括根据可用性测试结果对干预措施进行改进。在第 1 阶段,通过 9 次与 25 名 AA 女性(平均年龄 38.5 岁,标准差 7.8;平均 BMI 为 39.4kg/m2,标准差 7.3)的焦点小组讨论,确定了与 PA 相关的文化因素,并确定了如何利用社会认知理论的构建来设计 PA 干预措施。第 2 阶段包括对第 1 阶段定性数据的分析和结构化 PA 干预措施的开发。第 3 阶段专注于用于交付干预措施的智能手机应用程序的技术开发。第 4 阶段是 Smart Walk 的为期 1 个月的可用性测试(n=12 名女性;平均年龄 35.0 岁,标准差 8.5;平均 BMI 为 40kg/m2,标准差 5.0)。第 5 阶段包括根据可用性测试结果对干预措施进行改进。
五阶段过程促成了 Smart Walk 智能手机提供的 PA 干预措施的开发。该 PA 干预措施旨在针对社会认知理论的行为能力、结果预期、社会支持、自我效能和自我调节等构建,并解决 AA 女性的集体主义、种族自豪感和身体外貌偏好的深层结构社会文化特征。智能手机应用程序的主要功能包括(1)个人资料页面,(2)多媒体 PA 推广模块(即电子文本和视频),(3)论坛,以及(4)PA 自我监测工具。参与者还每周收到 3 条 PA 推广短信。
Smart Walk 的开发过程旨在最大限度地提高智能手机提供的 PA 干预措施的可用性、文化相关性和影响力。
