Brief summary
The goal of this multicenter randomized waitlist-controlled clinical trial is to evaluate whether an online Mindfulness-Based Intervention for Emotional Distress (MIED) can reduce emotional distress and reflux-related symptoms in adults with gastroesophageal reflux disease (GERD). GERD is a common chronic gastrointestinal condition that is frequently accompanied by anxiety, depressive symptoms, stress, and impaired quality of life. The main questions this study aims to answer are: Can online MIED reduce emotional distress in patients with GERD? Can online MIED reduce reflux-related symptoms and improve reflux-related quality of life? Are changes in psychological processes, such as distress tolerance, cognitive flexibility, experiential avoidance, emotional behaviors, and life engagement, associated with improvements in emotional distress and reflux symptoms? Researchers will compare participants receiving online MIED with participants in a waitlist control group receiving usual medical care and health management to determine whether online MIED leads to greater improvement over time. Participants will: complete screening and baseline assessments; be randomly assigned to either the online MIED intervention group or the waitlist control group; if assigned to the intervention group, complete an 8-week online MIED program with one session per week; continue necessary usual medical care during the study, while keeping medication use stable when possible; complete online questionnaires at baseline, during the intervention, after the intervention, and at 3, 6, 12, and 24 months after the intervention; report information on reflux symptoms, emotional distress, quality of life, sleep, stress, resilience, life satisfaction, healthcare use, intervention adherence, and adverse events.
Interventions
Participants will continue usual GERD treatment and health management during the 49-day observation period. They will not receive MIED, mindfulness training, or other structured psychological interventions during this period. Usual care may include medication, lifestyle advice, and necessary follow-up as determined by clinicians. The waitlist control group will complete assessments at the same time points as the MIED group. After the 2-year follow-up, participants in the waitlist control group who wish to receive the program will be offered the same MIED course.
The intervention is delivered via the internet and is grounded in the psychopathological diamond model of emotional distress proposed by Liu and colleagues. The program is supported by a MIED knowledge base, the Mindfulness Study public account, supervision and question-answer records, and official materials from Liu Xinghua and the MIED team. These resources are integrated into a WeChat self-help mini-program and the MIED Mindfulness Assistant, an artificial intelligence-supported system developed using large language models such as Tencent Hunyuan and DeepSeek R1. Together, these tools support participants' learning and practice over a continuous 49-day training period.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| GERD-HRQL | Baseline (T0); Week 3 (T1) and Week 5 (T2) during the intervention; immediately post-intervention at Week 8 (T3); and 3 months (T4), 6 months (T5), 12 months (T6), and 24 months (T7) post-intervention. | The GERD-HRQL is a self-report questionnaire used to assess the impact of gastroesophageal reflux symptoms on health-related quality of life. It evaluates symptom burden and the degree to which reflux symptoms affect daily functioning. Higher scores indicate poorer reflux-related quality of life. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Overall Anxiety Severity and Impairment Scale (OASIS) | Baseline (T0); Week 3 (T1) and Week 5 (T2) during the intervention; immediately post-intervention at Week 8 (T3); and 3 months (T4), 6 months (T5), 12 months (T6), and 24 months (T7) post-intervention. | The OASIS is a 5-item self-report measure designed to assess the frequency and severity of anxiety symptoms, as well as the extent of anxiety-related functional impairment and avoidance, over the past week. Each item is rated on a 5-point scale from 0 to 4, with total scores ranging from 0 to 20. Higher scores indicate greater overall anxiety severity and impairment. The OASIS has demonstrated good reliability and validity in both clinical and nonclinical samples (Norman et al., 2006). |
| Overall Depression Severity and Impairment Scale (ODSIS) | Baseline (T0); Week 3 (T1) and Week 5 (T2) during the intervention; immediately post-intervention at Week 8 (T3); and 3 months (T4), 6 months (T5), 12 months (T6), and 24 months (T7) post-intervention. | The ODSIS is a 5-item self-report measure designed to assess the frequency and severity of depressive symptoms, as well as depression-related functional impairment and avoidance, over the past week. Each item is rated on a 5-point scale from 0 to 4, with total scores ranging from 0 to 20. Higher scores indicate greater overall depression severity and impairment. The ODSIS has demonstrated good reliability and validity in both clinical and nonclinical samples (Bentley et al., 2014). |
| Gastroesophageal Reflux Disease Questionnaire (GERD-Q) | Baseline (T0); Week 3 (T1) and Week 5 (T2) during the intervention; immediately post-intervention at Week 8 (T3); and 3 months (T4), 6 months (T5), 12 months (T6), and 24 months (T7) post-intervention. | The GERD-Q is a 6-item self-report questionnaire used to assess the frequency and severity of gastroesophageal reflux symptoms and to monitor treatment response. Total scores range from 0 to 18, with higher scores indicating more severe reflux-related symptoms. |
| Reflux Symptom Index (RSI) | Baseline (T0); Week 3 (T1) and Week 5 (T2) during the intervention; immediately post-intervention at Week 8 (T3); and 3 months (T4), 6 months (T5), 12 months (T6), and 24 months (T7) post-intervention. | The RSI is a 9-item self-report questionnaire used to assess symptoms related to laryngopharyngeal reflux, including chronic cough, hoarseness, throat clearing, and globus sensation. Total scores range from 0 to 45, with higher scores indicating more severe reflux-related throat symptoms. |
| Generalized Anxiety Disorder-7 (GAD-7) | Baseline (T0); Week 3 (T1) and Week 5 (T2) during the intervention; immediately post-intervention at Week 8 (T3); and 3 months (T4), 6 months (T5), 12 months (T6), and 24 months (T7) post-intervention. | The GAD-7 is a 7-item self-report questionnaire used to assess the severity of anxiety symptoms over the past 2 weeks. Each item is rated on a 4-point scale from 0 ("not at all") to 3 ("nearly every day"), with total scores ranging from 0 to 21. Higher scores indicate greater anxiety severity. The GAD-7 has demonstrated good reliability and validity in both clinical and general populations (Spitzer et al., 2006). |
| Patient Health Questionnaire-9 (PHQ-9) | Baseline (T0); Week 3 (T1) and Week 5 (T2) during the intervention; immediately post-intervention at Week 8 (T3); and 3 months (T4), 6 months (T5), 12 months (T6), and 24 months (T7) post-intervention. | The PHQ-9 is a 9-item self-report questionnaire used to assess the severity of depressive symptoms over the past 2 weeks. Each item is rated on a 4-point scale from 0 ("not at all") to 3 ("nearly every day"), with total scores ranging from 0 to 27. Higher scores indicate greater depression severity. The PHQ-9 has demonstrated good reliability and validity in both clinical and general populations (Kroenke et al., 2001). |
| Treatment Inventory of Costs in Patients with Psychiatric Disorders (TIC-P) | Baseline (T0); immediately post-intervention at Week 8 (T3); and 3 months (T4), 6 months (T5), 12 months (T6), and 24 months (T7) post-intervention. | TIC-P is a widely used health economic instrument in mental health research for assessing psychiatric healthcare use and societal costs, including service utilization, medication use, and productivity losses (Bouwmans et al., 2013). In this study, TIC-P will be used to record healthcare resource consumption during the trial, including outpatient visits, medication costs, and other healthcare-related expenditures. To capture healthcare utilization more comprehensively, a self-developed healthcare utilization questionnaire will also be administered. |
| EuroQol 5-Dimension 5-Level (EQ-5D-5L) | Baseline (T0); Week 3 (T1) and Week 5 (T2) during the intervention; immediately post-intervention at Week 8 (T3); and 3 months (T4), 6 months (T5), 12 months (T6), and 24 months (T7) post-intervention. | This is one of the most widely used instruments in health economic evaluation for measuring health-related quality of life and includes five dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression, each with five response levels (Devlin \& Brooks, 2017; Herdman et al., 2011). The health utility values derived from EQ-5D-5L will be used to calculate Quality-Adjusted Life Years (QALYs) for cost-utility analysis (Drummond et al., 2015; Group, 1990). |
