The purpose of this study was to test a partnered, self-determination theory-informed mobile health intervention called SCI Step Together, using an 8-week randomized controlled trial design. The aim of SCI Step Together is to increase the quantity and quality of physical activity (PA) among adults with spinal cord injury (SCI) who walk. The SCI Step Together program provides PA modules and PA self-monitoring tools and facilitates peer and health coach support. Process, resource, management, and scientific feasibility were assessed, and participants completed questionnaires at baseline, mid-, and postintervention to assess determinants and outcomes of PA. Interviews were conducted to evaluate acceptability. Results suggest that the program demonstrated good feasibility, acceptability, and engagement. The intervention group (n = 11) had greater fulfillment of basic psychological needs and knowledge (p = .05) than the control group (n = 9). There were no significant interaction effects for other outcomes. The SCI Step Together program is feasible and acceptable and efficacious for improving some psychosocial variables. Results may inform SCI mobile health programs.

评估 mHealth 身体活动干预对行走的脊髓损伤成人的可行性、可接受性和参与度：一项随机对照试验。

本研究的目的是使用为期 8 周的随机对照试验设计，测试一种名为 SCI Step Together 的合作式、基于自我决定理论的移动健康干预措施。SCI Step Together 的目的是增加步行的脊髓损伤 (SCI) 成人的身体活动 (PA) 的数量和质量。SCI Step Together 计划提供 PA 模块和 PA 自我监控工具，并促进同伴和健康教练的支持。评估过程、资源、管理和科学可行性，参与者在基线、干预中期和干预后完成问卷调查，以评估 PA 的决定因素和结果。进行访谈以评估可接受性。结果表明，该计划展示了良好的可行性、可接受性和参与度。干预组 (n = 11) 比对照组 (n = 9) 更能满足基本的心理需求和知识 (p = .05)。其他结果没有显着的交互作用。SCI Step Together 项目是可行的、可接受的，并且对于改善一些社会心理变量是有效的。结果可能会告知 SCI 移动健康计划。
