This study aimed to explore the amenable factors contributing to the improvement in subjective well-being (SWB) immediately after a short-term visit to an urban park in an uncontrolled condition. Ninety-four park visitors from three urban parks completed a short questionnaire evaluating SWB (with two components: affect and life satisfaction) immediately before and after their park visit. In addition, their level of physical activity was tracked by wearing an accelerometer during the park visit. Results indicated a significant improvement in SWB, affect, and life satisfaction scores of park visitor participants from before and after their visit. Duration of park visit was bivariately associated with SWB scores, and independently associated with the improvement in life satisfaction scores, controlling for parks and age, after the visit; a 20.5-min park visit predicted the highest overall accuracy (64%) improvement in life satisfaction. It is recommended that design of the park space should attract visitors to stay for at least 20 min in the park.

参观城市公园后立即与主观幸福感变化相关的因素。

这项研究旨在探讨在不受控制的情况下短期访问城市公园后立即改善主观幸福感（SWB）的因素。来自三个城市公园的94个公园游客在访问公园前后分别完成了一份简短的问卷调查，以评估SWB（包括情感和生活满意度两个部分）。此外，在参观公园期间，佩戴加速度计可以追踪他们的身体活动水平。结果表明，公园访客参与者访问前后的SWB，情感和生活满意度得分均得到显着改善。参观公园的持续时间与SWB得分有二元相关性，并且与参观后控制公园和年龄的生活满意度得分的提高独立相关；一个20。5分钟的公园游览预计生活满意度将提高最高的整体准确性（64％）。建议公园空间的设计应吸引游客至少在公园中停留20分钟。
