许多人在实现与智能手机使用相关的行为目标方面经常遇到困难。以往的研究多采用自我反省、社会支持等行为改变策略来解决这一问题。然而，人们对封锁等限制性和强制性干预措施的有效性和用户体验知之甚少。在这项工作中，我们开发了“GoalKeeper”，这是一款智能手机干预应用程序，通过限制性干预机制将用户锁定在自定义的日常使用时间限制内。我们对36名参与者进行了为期四周的现场实验，以调查不同强度的限制性干预的效果和用户体验。结果表明，限制性机制比非限制性机制（如警告）更有效。然而，我们发现，限制性机制造成更多的挫折和压力的用户，主要是由于使用环境和需求的多样性。根据我们的研究结果，我们提取的实际意义设计的限制性机制，平衡的干预有效性的行为变化和用户的可接受性的灵活性。
Many people often experience difficulties in achieving behavioral goals related to smartphone use. Most of prior studies approached this problem with various behavior change strategies such as self-reflection and social support. However, little is known about the effectiveness and user experiences of restrictive and coercive interventions such as blocking. In this work, we developed "GoalKeeper," a smartphone intervention app that locks the user into the self-defined daily use time limit with restrictive intervention mechanisms. We conducted a four-week field experiment with 36 participants to investigate the effects and user experiences of varying intensities of restrictive interventions. The results showed that restrictive mechanisms are more effective than non-restrictive mechanisms such as warning. However, we found that restrictive mechanisms caused more frustration and pressure to the users, mainly due to diversity of usage contexts and needs. Based on our study results, we extracted practical implications for designing restrictive mechanisms that balance the intervention effectiveness for behavioral changes and the flexibility for user acceptability.
