简要总结
This study aims to evaluate the acceptability and effectiveness of a positive psychology-based ecological momentary intervention (EMI) for enhancing well-being in college students. A three-arm randomized controlled trial (RCT) will assess the impact of a dynamic EMI that delivers personalized exercises when participants' real-time affect or well-being scores fall below a predefined threshold, compared to control conditions. Primary outcomes include changes in well-being and mental health, evaluated through a mixed-methods approach combining quantitative measures and qualitative interviews.
详细描述
This study aims to evaluate a Positive Psychology-based Ecological Momentary Intervention (EMI) designed to enhance well-being among college students. A three-arm randomized controlled trial (RCT) will be conducted to examine the intervention's effectiveness. The EMI integrates core positive psychology practices-such as gratitude, mindfulness, and acts of kindness-and is delivered through a mobile application in real time. The intervention features a dynamic, adaptive algorithm that provides personalized exercises when participants' real-time affect or well-being scores fall below a predefined threshold. Primary outcomes include changes in well-being and mental health . A mixed-methods design will be employed, combining quantitative assessments at baseline, post-intervention, and one-month follow-up with qualitative post-intervention interviews to gain an in-depth understanding of the intervention's impact and user experience.

研究组 & 干预措施
EMI Group
Participants in this group will use the app which delivers EMI exercises adaptively. Twice daily, the app assesses their momentary affect and well-being. If scores fall below a preset threshold, a corresponding intervention exercise (e.g., gratitude, mindfulness) is automatically triggered. They also complete a daily evening assessment. The intervention lasts 14 days.
干预措施: Ecological Momentary Intervention (Behavioral)
Active Control Group
Participants in this group will use the app to complete a fixed set of six EMI exercises twice daily, regardless of their current emotional state. This controls for the general effect of receiving the intervention content and frequency. They also complete the same daily evening assessment as the other groups. The phase lasts 14 days.
干预措施: Active Control (Behavioral)
No-Intervention Control Group
Participants in this group will use the app only for assessment purposes. They complete the same twice-daily momentary assessments and the daily evening assessment as the other groups, but do not receive any intervention exercises. This controls for the effects of repeated self-monitoring. The phase lasts 14 days.
结局指标
主要结局
Affect
时间窗: Baseline (pre-intervention); Immediately after the intervention (2 week after baseline)); 1-month follow-up (1 month after intervention)
The 20-item Positive and Negative Affect Schedule Short Form (PANAS-SF) will be used to measure affective states. This scale comprises two subscales: Positive Affect (10 items) and Negative Affect (10 items). Each item is rated on a 5-point scale from 1 (very slightly or not at all) to 5 (extremely). Higher scores on each subscale indicate higher levels of the respective affect.
Happiness
时间窗: Baseline (pre-intervention); Immediately after the intervention (2 weeks after baseline); 1-month follow-up (1 month after intervention)
The 4-item Subjective Happiness Scale (SHS) will be utilized to assess participants' subjective happiness. Each item will be rated on a 7-point Likert scale. Elevated scores on the scale indicate a greater level of subjective happiness.
Flourishing
时间窗: Baseline (pre-intervention); Immediately after the intervention (2 weeks after baseline); 1-month follow-up (1 month after intervention)
The 8-item Flourishing Scale (FS) will be used to measure psychological well-being and self-perceived success in important areas such as relationships, self-esteem, and purpose. Each item is rated on a 7-point scale from 1 (strongly disagree) to 7 (strongly agree), with higher scores indicating a greater level of psychological well-being.
Satisfaction with Life
时间窗: Baseline (pre-intervention); Immediately after the intervention (2 weeks after baseline); 1-month follow-up (1 month after intervention)
Satisfaction with life is measured by the 5-item Satisfaction with Life Scale (SWLS). All items are rated on a 7-point scale from 1 (strongly disagree) to 7 (strongly agree), with higher scores indicating higher satisfaction with life.
Psychological distress
时间窗: Baseline (pre-intervention); Immediately after the intervention (2 weeks after baseline); 1-month follow-up (1 month after intervention
The 21-item Depression Anxiety Stress Scale (DASS-21) will be used to measure the negative emotional states of depression, anxiety, and stress. Each subscale contains 7 items, rated on a 4-point severity scale from 0 (did not apply to me at all) to 3 (applied to me very much, or most of the time). Higher scores indicate more severe levels of depression, anxiety, or stress.
次要结局
- State Subjective Happiness(During the 14-day intervention period, this measurement is conducted twice per day as part of the momentary assessments, and once each evening as part of the Daily Diary assessment at 9:00 PM.)
- State affect(During the 14-day intervention period, this measurement is conducted twice per day as part of the momentary assessments, and once each evening as part of the Daily Diary assessment at 9:00 PM.)
- State Well-Being(During the 14-day intervention period, this measure is also administered each evening at 9:00 PM as part of the Daily Diary assessment.)
- State Anxiety and Depression(During the 14-day intervention period, this measure is also administered each evening at 9:00 PM as part of the Daily Diary assessment.)
- State Stress(During the 14-day intervention period, this measure is also administered each evening at 9:00 PM as part of the Daily Diary assessment.)
