We aimed to evaluate the feasibility and effectiveness of a brief community-based intervention to promote physical activity (PA) and the mental well-being of adults in Hong Kong.
A pilot cluster randomized controlled trial was conducted in 15 family service centers. The intervention group (N = 162, 8 centers) received two 2-h interventions uniquely combining "Sharing, Mind and Enjoyment (SME)," Zero-time Exercises (ZTEx), positive psychology, and simple family games. "Sharing" involved promoting PA among families and peers, "Mind" captured positive emotions during PA, and "Enjoyment" assessed engagement of PA. ZTEx are simple PAs to reduce sedentary behaviors and enhancing PA and fitness and require minimal time and no cost or equipment. The control group (N = 152, 7 centers) received interventions unrelated to SME. Primary outcomes were PA-related SME at a 3-month follow-up after completing the baseline questionnaire. Secondary outcomes included subjective happiness, well-being, and family-related outcomes. Participants reported self-perceived changes at 1- and 3-month. Nine focus group discussions with the participants and 4 individual in-depth interviews with community service providers were conducted.
The retention rate at1 month was 90.1% for the intervention group and 95.4% for the control group, while at 3 months, it was 83.3% and 92.8%, respectively. The intervention group showed significantly greater positive changes in PA-related outcomes than the control group at 3-month follow-up (Cohen's = 0.33-0.42, all < .05). Most secondary outcomes were non-significantly different between the 2 groups. However, more than 90% of participants in the intervention group reported self-perceived positive changes at 1- and 3-month follow-ups. The qualitative data showed that ZTEx was popular with families due to its simplicity.
Our trial showed the feasibility of implementing the brief interventions and the potential benefits for promoting physical activity in community adults.

我们旨在评估一项简短的社区干预措施在促进香港成年人身体活动（PA）和心理健康方面的可行性和有效性。
在15个家庭服务中心进行了一项试点整群随机对照试验。干预组（N = 162，8个中心）接受了两次2小时的干预，独特地结合了“分享、心灵与享受（SME）”、零时运动（ZTEx）、积极心理学和简单的家庭游戏。“分享”包括在家庭和同伴中促进身体活动，“心灵”捕捉身体活动期间的积极情绪，“享受”评估身体活动的参与度。ZTEx是简单的身体活动，可减少久坐行为并增强身体活动和健康，所需时间最少，无需成本或设备。对照组（N = 152，7个中心）接受与SME无关的干预。主要结局是在完成基线问卷后3个月随访时与身体活动相关的SME。次要结局包括主观幸福感、健康状况和与家庭相关的结局。参与者报告了在1个月和3个月时自我感知的变化。与参与者进行了9次焦点小组讨论，并与社区服务提供者进行了4次个人深入访谈。
干预组1个月时的保留率为90.1%，对照组为95.4%；3个月时，分别为83.3%和92.8%。在3个月随访时，干预组在与身体活动相关的结局方面显示出比对照组更大的积极变化（科恩效应量 = 0.33 - 0.42，均P <.05）。两组之间的大多数次要结局无显著差异。然而，干预组中超过90%的参与者在1个月和3个月随访时报告了自我感知的积极变化。定性数据表明，ZTEx因其简单性而受到家庭欢迎。
我们的试验表明实施简短干预措施的可行性以及对促进社区成年人身体活动的潜在益处。
