Brief summary
This proposed study aims to evaluate whether integrating mindfulness into an undergraduate biology course (Mindful Physiology) influences students' trait and applied mindfulness, well-being, and physiological stress reactivity. The primary questions are 1. Would completing the Mindful Physiology course increase applied mindfulness? 2. Would completing the class increase trait mindfulness? 3. Would completing the class increase subjective well-being? 4. Would completing the class reduce physiological stress response to an acute social stressor?
Detailed description
The proposed study aims to evaluate whether integrating mindfulness practice into an undergraduate biology course influences students' levels of applied mindfulness and stress regulation self-efficacy. A two-arm design will compare students who receive the intervention (a 10-week biology course with integrated mindfulness practice) with a control group of waitlisted students for the course, who will receive only university wellness resources. Participants all attempted to register for the course during a set course selection period at the college and were randomly registered or waitlisted by the College Registrar. Students registered and waitlisted for the course will be recruited for the study, and those who provide informed consent will be enrolled. Data on trait mindfulness, applied mindfulness, and well-being will be collected at baseline and the conclusion of the intervention (\ 10 weeks). Additionally, over weeks 8 and 9, participants will be invited for an in-person lab visit for a Trier Social Stress Test (TSST) to assess their physiological response to an acute social stressor. This study aims to examine whether integrating mindfulness practice into a ten-week undergraduate-level biology course will enhance trait and applied mindfulness, well-being, and stress regulation. We hypothesize that completing this ten-week course will (1) increase applied mindfulness, (2) increase trait mindfulness, (3) increase well-being, and (4) decrease physiological stress response to an acute social stressor. For the primary outcomes, we will examine the between-group differences in changes in applied mindfulness, trait mindfulness, heart rate response to the TSST, and the WHO-5 Index, using linear regression models with change scores in each outcome as the dependent variable and the group status as the independent variable, adjusted for age and sex. We will report Cohen's d to estimate the effect sizes. As exploratory analyses, we will examine the dose-response relationship between practice time (assessed with self-report practice time) and changes in primary and other outcomes over the term. Additionally, we will rerun the primary analysis by combining data from Spring 2026 with data from the cohort from the previous cycle (Spring 2025). Further, we will explore any between-group differences in changes in heart rate and heart rate variability during the TSST preparation and speaking task, separately, with linear regression models, adjusted for age and sex. All analyses will consider p-values \< 0.05 as statistically significant.
Interventions
BEHAVIORALBiology Course with Integrated Mindfulness
The intervention, Mindful Physiology, is an undergraduate-level biology course embedded with mindfulness practices. Over 10 weeks, students attend 19 110-minute sessions that combine didactic lectures, labs, and quizzes with \~20 minutes of mindfulness practice daily, in the tradition of Thích Nhất Hạnh's Plum Village Zen Buddhism. Students complete daily mindfulness logs (credited regardless of duration) and weekly reflections on course content or practice. Students are encouraged to practice for 15 minutes daily outside of class, at least 5 days a week. They are also required to attend a group mindfulness session of 30 mins or longer each week. Students are required to attend either a 4.5-hour on-campus mindfulness retreat or a two-day (16-hour) on-campus mindfulness retreat.

Intervention model description
The intervention group will consist of students enrolled in the Mindful Physiology course (Biology 3) at Dartmouth College in the spring 2026 term (3/30/2026- 6/3/2026). The control group will enroll students waitlisted for the course during the Spring 2026 term. The control participants will receive university wellness resources as usual. These include access to counseling and psychotherapy services at the university's counseling center, wellness advising at the student wellness center, and campus-wide wellness programs, such as weekly group yoga and meditation sessions and a free subscription to the Headspace app.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Applied Mindfulness | Baseline and intervention completion (~10 weeks) | Students will complete the Applied Mindfulness Process Scale (AMPS) at baseline and post-intervention completion. The scale consists of 15 questions that quantify the application of mindfulness skills to navigate difficult situations and stressors in life. The AMPS encompasses three subscales: decentering, negative emotion regulation, and positive emotion regulation. The total scores are the sum of the item scores. The total possible scores range from 0 to 60. Higher scores reflect a more active use of mindfulness practice in everyday life. The scale demonstrated high internal consistency (Cronbach's α = 0.91) among 134 adults in the original study. |
| Trait Mindfulness | Baseline and intervention completion (~10 weeks) | Trait mindfulness will be assessed with the Five Facet Mindfulness Questionnaire (FFMQ), a 39-item questionnaire evaluating five distinct components of mindfulness: observation (8 items), description (8 items), aware actions (8 items), non-judging of inner experience (8 items), and non-reactivity to inner experience (7 items). The total score is the average across the five subscales. Possible scores range from 1 to 5, with higher scores indicating higher dispositional mindfulness. |
| Physiological Stress Response to an Acute Stressor | Intervention completion (~8 and 9 weeks) | At the time of intervention completion, physiological stress reactivity will be evaluated using the online version of the Trier Social Stress Test (TSST) in our laboratory (Heyers et al., 2025). During the TSST, heart rate will be measured using a chest-worn Polar H10 (Polar Electro Oy, Kempele, Finland) (Schaffarczyk et al., 2022) and video-based photoplethysmography (PPG) (Pirzada et al., 2023). Wrist collected PPG heart rate data will also be measured during the TSST-OL (ActiGraph LEAP; Ametris, Pensacola, Florida). Raw inter-beat intervals will be recorded via Bluetooth pairing with an accelerometer (ActiGraph wGT3X-BT; Ametris, Pensacola, Florida). The mean heart rate (MHR) will be computed during the baseline resting phase, the TSST (speech preparation and speaking), and the recovery phase (Nyklíček et al., 2013). Reactivity to the acute stressor will be operationalized as differences in heart rate parameters during the TSST (preparation + speaking) compared to the baseline. |
| Well-Being | Baseline and intervention completion (~10 weeks) | Well-being will be assessed with the 5-item World Health Organization Well-Being Index (WHO-5). Participants will rate five positively phrased items on subjective well-being, i.e., "I have felt cheerful and in good spirits." Responses are anchored from 0 (none of the time) to 5 (all the time). The total score is the sum of item responses ranging from 0 to 25, with 25 indicating the maximum possible mental well-being. The index has shown high internal consistency with α = 0.86 and test-retest reliability of r = 0.77 in 903 college students. |
