A field experiment on subgoal framing to boost volunteering: The trade-off between goal granularity and flexibility.
通过实地实验发现，将200小时的志愿服务总目标分解为更细的子目标（如每周4小时或每两周8小时）可使志愿服务时长增加8%，且每两周8小时的灵活子目标效果更持久。
= 900) suggests that the subgoal framing tested in the field could benefit goal seekers by bolstering their self-efficacy and goal commitment, and by discouraging procrastination. Our field experiment finds that reframing an overarching goal of 200 hr of volunteering into more granular subgoals (either 4 hr of volunteering every week or 8 hr every 2 weeks) increased hours volunteered by 8% over a 12-week period. Further, increasing subgoal flexibility by breaking an annual 200-hr volunteering goal into a subgoal of volunteering 8 hr every 2 weeks, rather than 4 hr every week, led to more durable benefits.
