Adherence challenges are common among digital mental health interventions (DMHIs). Single-session DMHIs may help by providing a low-intensity intervention that takes less time to complete. This pilot randomized controlled trial sought to evaluate the acceptability and preliminary efficacy of a single-session DMHI based on acceptance and commitment therapy (ACT) in a non-clinical sample of college students. The trial was pre-registered (NCT06139718). A total of 61 students were recruited, which was below the target of 100 participants. The participants were randomized to the single-session ACT DMHI or to a waitlist condition, with assessments completed at 1-week and 1-month follow-ups. The vast majority of participants (87%) completed the single-session ACT program. The participants provided high program satisfaction ratings. There were no differences between conditions on psychological flexibility, distress, or mental health help seeking. However, the participants assigned to ACT improved significantly more than the waitlist on well-being from baseline to 1-month follow-up ( = 0.29). Overall, the results were mixed, with some support for the acceptability and potential efficacy of a single-session ACT DMHI but also a lack of effect, most notably on psychological flexibility as the process of change in ACT.
依从性挑战在数字心理健康干预（DMHIs）中很常见。单节次DMHIs可能通过提供一种耗时较短的低强度干预来发挥作用。这项初步随机对照试验旨在评估基于接受与承诺疗法（ACT）的单节次DMHI在大学生非临床样本中的可接受性和初步疗效。该试验已预先注册（NCT06139718）。共招募了61名学生，低于100名参与者的目标。参与者被随机分配到单节次ACT DMHI组或等待列表组，并在1周和1个月随访时完成评估。绝大多数参与者（87%）完成了单节次ACT项目。参与者对该项目的满意度很高。在心理灵活性、痛苦程度或寻求心理健康帮助方面，两组之间没有差异。然而，从基线到1个月随访，分配到ACT组的参与者在幸福感方面的改善明显超过等待列表组（=0.29）。总体而言，结果喜忧参半，单节次ACT DMHI的可接受性和潜在疗效得到了一些支持，但也存在缺乏效果的情况，最明显的是在作为ACT改变过程的心理灵活性方面。
