Effects of a Digital Micro-Movement Nudge Intervention on Well-Being and Academic Outcomes in College Students

Effects of a Digital Micro-Movement Nudge Intervention on Well-Being and Academic Outcomes in College Students: A Randomized Controlled Trial

The goal of this randomized controlled study is to learn whether a 21-day physical resilience (movement-based) program can improve mental well-being, emotional regulation, and academic functioning in university students.

The main questions it aims to answer are:

Does participation in a 21-day physical resilience program improve students' well-being (e.g., depression, anxiety, stress, affect, life satisfaction, and perceived health)?

Does the program improve students' academic and self-regulatory outcomes (e.g., engagement, burnout, procrastination, productivity, emotion regulation, coping, and self-control capacity)?

Researchers will compare students who complete the physical resilience program immediately to students in a waitlist control group to see whether participation in the program leads to greater improvements in well-being and academic-related outcomes.

Participants will:

Sign up online and provide informed consent

Be randomly assigned to either the intervention group or a waitlist control group

Receive daily micro-movement tasks and reminders via Telegram for 21 days (intervention group)

Complete online questionnaire surveys at baseline, post-intervention, and a 2-week follow-up

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Intervention group	Behavioral: Physical resilience; The intervention is a 21-day, digitally delivered physical resilience program consisting of daily, brief, movement-based activities designed to support mental well-being and academic functioning in university students. The program includes low-intensity physical movement, breathing exercises, and body-based regulation practices that can be completed independently without specialized equipment or prior physical training. Participants assigned to the intervention group receive one structured movement task per day for 21 consecutive days. Tasks are delivered via a Telegram channel, accompanied by brief digital reminders to prompt engagement. Each task is designed to be short in duration, flexible in timing, and feasible within daily routines, emphasizing consistency rather than physical exertion or performance. The intervention is self-guided and asynchronous, with no in-person contact, live sessions, or direct supervision.; Other Names: Digital Micro-Movement Nudge Intervention
No Intervention: Waitlist Control

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
State anxiety	State anxiety will be assessed using the 6-item Spielberger State-Trait Anxiety Inventory STAI-6 (Marteau & Bekker, 1992). Six items (e.g., "I was worried these past 2 weeks.") rated from 1 (Not at all) to 4 (Very much so) will be averaged for a composite score. Higher scores indicate greater levels of anxiety.	Enrollment to the end of intervention at 3 weeks and the end of follow-up at 5 weeks
Procrastination	Procrastination will be assessed using six items from the Irrational Procrastination Scale (Steel, 2002), such as "At the end of these past 2 weeks, I know I could have spent the time this week better." Participants will respond on a 1-5 scale (1 = Very seldom or not true of me, 5 = Very often true, or true with me), and higher average scores indicate higher levels of procrastination.	Enrollment to the end of intervention at 3 weeks and the end of follow-up at 5 weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Productivity	Productivity will be assessed using the Task Performance subscale of the Individual Work Performance Questionnaire (IWPQ; Koopmans et al., 2013, 2014), adapted to the academic context. Participants will respond to five items (e.g., "I was able to plan my work so that I finished it on time") with reference to their schoolwork. Items will be rated on a 6-point scale from 0 (seldom) to 5 (always) and then the scores will be averaged, with higher scores indicating greater productivity.	Enrollment to the end of intervention at 3 weeks and the end of follow-up at 5 weeks
Study Burnout	Study burnout will be measured using the 9-item Study Burnout Inventory (Salmela-Aro & Read, 2017). Participants will indicate how well each item described their experiences (e.g., "I felt a lack of motivation in studying and often think of giving up") on a 6-point scale from 1 (Completely disagree) to 6 (Completely agree). Scores will be averaged, with higher scores indicating greater academic burnout.	Enrollment to the end of intervention at 3 weeks and the end of follow-up at 5 weeks
Study Engagement	Study engagement will be measured using the 9-item Study Engagement Inventory (Salmela-Aro & Read, 2017). Participants will rate items such as "I found studying full of meaning and purpose" based on their experiences. Responses will be given on a 6-point Likert scale ranging from 1 (Completely disagree) to 6 (Completely agree) and higher scores will indicate greater levels of academic engagement.	Enrollment to the end of intervention at 3 weeks and the end of follow-up at 5 weeks
Implementation intention	Implementation intention will be measured using the single item "In the past 14 days, I have taken steps to achieve my goals for the month." scored from 1 (Strongly disagree) to 5 (Strongly agree), where a higher score indicates higher implementation intention.	Enrollment to the end of intervention at 3 weeks and the end of follow-up at 5 weeks
Goal Progress	Goal progress will be measured using the single item "In the past 14 days, I have seen progress towards my goals for the month." scored from 1 (Strongly disagree) to 5 (Strongly agree), where a higher score indicates higher goal progress.	Enrollment to the end of intervention at 3 weeks and the end of follow-up at 5 weeks
Depression	Depression will be measured using an adapted version of the 10-item Short Depression Scale Revised (CES-D-R 10) (Andresen et al., 1994). The scale includes the sample item "I felt that everything I did was an effort." and is scored from 1 (Rarely or none of the time) to 4 (All of the time). Scores will be averaged and higher scores indicate higher risk of depression.	Enrollment to the end of intervention at 3 weeks and the end of follow-up at 5 weeks
Life Satisfaction	Life satisfaction will be measured using an adapted version of Diener's Satisfaction With Life Scale (SWLS). The scale includes 5 items e.g. "In most ways, these past 2 weeks have been close to ideal" and is scored from 1 (Strongly disagree) to 7 (Strongly agree) (Diener et al., 1985). Scores will be summed and higher scores indicate higher life satisfaction.	Enrollment to the end of intervention at 3 weeks and the end of follow-up at 5 weeks
Perceived Stress	Perceived stress will be measured by an adapted version of the 4-item Perceived Stress Scale (PSS) developed by Cohen and colleagues (Cohen et al., 1983). One sample item includes "In the last 2 weeks, how often have you felt difficulties piling up so high that you could not overcome them?" and items are scored from 0 (Never) to 4 (Very often). The composite score is calculated by summing the scores of all items; higher scores indicate higher levels of perceived stress.	Enrollment to the end of intervention at 3 weeks and the end of follow-up at 5 weeks
Positive and Negative Affect	Positive Affect (PA) and Negative Affect (NA) will be evaluated using the Circumplex Model of Affect (Russell, 1980). Participants will rate feelings such as 'Energetic' and 'Dejected' experienced over the past two weeks, from a scale of 1 to 5 (1 = Not at all, 5 = Extremely).	Enrollment to the end of intervention at 3 weeks and the end of follow-up at 5 weeks
Coping	Coping strategies will be assessed using the Brief COPE (Carver, 1997) which is a 28-item self-report measure assessing a range of adaptive and maladaptive coping responses to stress. Participants will indicate how frequently they have engaged in various coping behaviours in response to stress over the past two weeks (e.g., "I've been taking action to try to make the situation better"). Items will be rated on a 4-point scale from 1 (I haven't been doing this at all) to 4 (I've been doing this a lot). Scores will then be averaged for each coping strategy, with higher scores indicating greater use of that coping strategy.	Enrollment to the end of intervention at 3 weeks and the end of follow-up at 5 weeks
Emotion Regulation	Emotion regulation will be assessed using the Emotion Regulation Questionnaire (ERQ; Gross & John, 2003), which is a 10-item self-report measure assessing two emotion regulation strategies: cognitive reappraisal and expressive suppression. Participants will indicate the extent to which they agree with statements describing how they typically regulate their emotions (e.g., "I control my emotions by changing the way I think about the situation I'm in"). Items are rated on a 7-point scale from 1 (strongly disagree) to 7 (strongly agree). Subscale scores will be computed by averaging items corresponding to cognitive reappraisal and expressive suppression, with higher scores indicating greater use of the respective emotion regulation strategy.	Enrollment to the end of intervention at 3 weeks and the end of follow-up at 5 weeks
Self-Control Capacity	Self-control capacity will be assessed using the Brief State Self-Control Capacity Scale (BSSCS; Lindner et al., 2019), which is a 5-item self-report measure assessing individuals' perceived momentary self-control resources. Participants will indicate the extent to which each statement reflects their experiences over the past two weeks (e.g., "I felt like my willpower was gone"). Items are rated on a 7-point scale from 1 (not true) to 7 (very true). Items will be averaged to compute a composite score, with higher scores indicating greater state self-control capacity.	Enrollment to the end of intervention at 3 weeks and the end of follow-up at 5 weeks
Perceived Health	Perceived health will be assessed using a single-item self-report measure of general health status. Participants will respond to the question, "How would you rate your physical health over the past two weeks?" Responses will be rated on a 5-point scale from 1 (Poor) to 5 (Excellent). Higher scores indicate better perceived physical health.	Enrollment to the end of intervention at 3 weeks and the end of follow-up at 5 weeks
