摘要

背景:即时适应干预(JITAIs)旨在为日常生活中的关键时刻提供心理支持。目的:本预注册研究旨在评估社会支持JITAI对等待心理治疗的亚临床和临床抑郁症状个体的可行性。由生态瞬时评估(EMA)报告引发的干预措施鼓励参与者激活他们的(数字)社会支持网络。方法:共有25名参与者在18天的干预期内完成了2689份EMA调查,并接受了377份jitai,其中包括一项微随机试验,以比较4种触发干预的策略:固定的痛苦变量截止点、痛苦变量的个性化阈值(通过Shewhart控制图)、瞬间支持需求和不干预。结果:结果显示高可行性,参与者完成了85.37%(2689/3150)的EMA调查,显示出较低的研究相关损失率(7%,总损失率为17%),并且报告了最小的技术问题。参与和感知的帮助是异质性的和适度的,在干预被触发后,参与者在三分之一的情况下寻求支持。尽管触发的频率较低,但与基于痛苦指标的jitai相比,由自我报告的支持需求触发的jitai在促进寻求支持行为方面被评为更适时、更有帮助、更有效。额外的定性分析表明,诸如时间限制和认为无法获得支持提供者等障碍可能会影响寻求支持的行为。探索性有效性分析表明,在接受jitai后减少痛苦的Cohen效应值在0.06至0.14之间。结论:本研究结果表明社会支持JITAI是可行的,具有较高的依从性和最小的技术问题。然而,需要进一步的研究来评估JITAI的有效性,并优化触发策略,以解决个人需求和参与障碍。

A Social Support Just-in-Time Adaptive Intervention for Individuals With Depressive Symptoms: Feasibility Study With a Microrandomized Trial Design.

Background: Just-in-time adaptive interventions (JITAIs) aim to provide psychological support during critical moments in daily life.

Objective: This preregistered study aims to evaluate the feasibility of a social support JITAI for individuals with subclinical and clinical levels of depressive symptoms awaiting psychotherapy. Triggered by ecological momentary assessment (EMA) reports, the intervention encouraged participants to activate their (digital) social support networks.

Methods: A total of 25 participants completed 2689 EMA surveys and received 377 JITAIs over an 18-day intervention period, including a microrandomized trial, to compare 4 strategies to trigger an intervention: fixed cutoff points of distress variables, personalized thresholds (through Shewhart control charts) of distress variables, momentary support need, and no intervention.

Results: The results showed high feasibility, with participants completing 85.37% (2689/3150) of the EMA surveys, exhibiting a low study-related attrition rate (7%; total attrition rate was 17%), and reporting minimal technical issues. Engagement and perceived helpfulness were heterogeneous and moderate, with participants seeking support in one-third of the instances after an intervention was triggered instances. JITAIs triggered by self-reported need for support were rated as more appropriately timed, helpful, and effective for promoting support-seeking behavior compared to those based on distress indicators, despite being triggered less frequently. Barriers, such as time constraints and perceived unavailability of support providers, likely affected support-seeking behavior, as indicated by additional qualitative analyses. Exploratory effectiveness analyses indicated Cohen d effect sizes between 0.06 and 0.14 in reducing distress after JITAIs were received.

Conclusions: The findings of this study demonstrate that a social support JITAI is feasible to implement, with high compliance and minimal technical issues. However, further research is needed to evaluate the JITAI's effectiveness and optimize trigger strategies in addressing individual needs for and barriers to engagement.
