Repetitive negative thinking (RNT) has been identified as a transdiagnostic process that is involved in various forms of psychopathology, including anxiety and depression. This randomized controlled trial compared a 5-week internet and app-based gratitude intervention (intervention group; IG) with adherence-focused guidance against a wait list control group (WLG) in reducing RNT in a sample with elevated RNT.
A total of 260 individuals were randomized to either the IG or the WLG. Data were collected at baseline (T1), within one week post intervention (T2), and at three (3-MFU) and six-months of follow-up (6-MFU; for IG only). The primary outcome was RNT. Secondary outcomes included other mental health outcomes and resilience factors.
Participants of the IG reported significantly less RNT at T2 (d = 0.61) and 3-MFU (d = 0.75) as compared to WLG. Improvements were sustained until 6-MFU. Significant, small to moderate effect sizes were identified for most secondary outcomes at T2 and 3-MFU. Furthermore, results of mediation analyses revealed that the gratitude intervention exerts its effect on anxiety and depression by reducing the risk factor of RNT, while the mediating role of resilience was less clear.
The gratitude intervention investigated in this study was found to be effective in reducing RNT. Gratitude interventions might affect mental health by two parallel pathways: increasing resources and reducing risk factors.

重复消极思维（RNT）已被确定为一种跨诊断过程，涉及各种形式的精神病理学，包括焦虑和抑郁。本随机对照试验比较了 5 周的基于互联网和应用程序的感恩干预（干预组；IG）与基于坚持的指导与等待名单对照组（WLG），以减少 RNT 在 RNT 升高的样本中的 RNT。
共有 260 人被随机分配到 IG 或 WLG。数据在基线（T1）、干预后一周内（T2）以及 3 个月（3-MFU）和 6 个月随访（仅 IG）时收集。主要结局为 RNT。次要结局包括其他心理健康结局和恢复力因素。
与 WLG 相比，IG 参与者在 T2（d=0.61）和 3-MFU（d=0.75）时报告的 RNT 明显减少。改善可持续到 6-MFU。在 T2 和 3-MFU 时，大多数次要结局均显示出显著的小到中度效应量。此外，中介分析结果表明，感恩干预通过降低 RNT 的风险因素对焦虑和抑郁产生影响，而恢复力的中介作用则不太明确。
本研究中调查的感恩干预被发现可有效降低 RNT。感恩干预可能通过两种平行途径影响心理健康：增加资源和减少风险因素。
