The purpose of this study was to evaluate the effectiveness of the Fun For Wellness (FFW) online intervention to increase well-being actions in adults with obesity in the United States in relatively uncontrolled settings. The FFW intervention is guided by self-efficacy theory. The study design was a large-scale, prospective, double-blind, and parallel-group randomized controlled trial. Data collection occurred at baseline, 30 days after baseline, and 60 days after baseline. Participants (N = 667) who were assigned to the FFW group (n_FFW = 331) were provided with 30 days of 24-hr access to FFW. Supportive evidence was provided for the effectiveness of FFW in real-world settings to promote, either directly or indirectly, three dimensions of well-being actions: community, occupational, and psychological. This study shows that theory-based intervention may be effective in promoting well-being actions in adults with obesity in the United States.

本研究的目的是评估 Fun For Wellness (FFW) 在线干预在相对不受控制的环境中增加美国肥胖成人的幸福感的有效性。FFW 干预以自我效能理论为指导。研究设计是一项大规模、前瞻性、双盲、平行组随机对照试验。数据收集发生在基线、基线后 30 天和基线后 60 天。 被分配到 FFW 组 ( n _FFW ) 的参与者 ( N = 667) = 331) 提供 30 天 24 小时访问 FFW。为 FFW 在现实环境中直接或间接促进福祉行动的三个方面的有效性提供了支持性证据：社区、职业和心理。这项研究表明，基于理论的干预可能有效促进美国肥胖成人的健康行动。
