Brief Summary

This study will evaluate engagement, usability, and psychological outcomes associated with participation in smartphone-based stress management or mindfulness training program among young adults. The study will compare multiple versions of a digital training program delivered through the Equa mobile application. Participants will be individually randomized to one of several app-based training programs using a stratified randomization procedure. Each program consists of guided daily lessons completed over a 14-day period and is designed to support stress management and well-being through structured skill development activities. Primary objectives include evaluating user satisfaction and usability of the digital platform and assessing changes in mindfulness-related skills and mental distress over time. Participants will: Complete surveys assessing demographics and psychological well-being at baseline, post-intervention, and one-month follow-up. Complete a 14-day smartphone-delivered training program consisting of guided lessons while physiological data are collected using wearable sensors. Some participants may receive additional in-app features designed to support personalized learning or engagement with training lessons. Some participants will complete brief questionnaires before and after selected lessons to assess short-term changes associated with lesson participation.

Outcome Measures

Primary Outcomes (5)

  • Equa Program Engagement

    In order to evaluate differential engagement over the 14 day training period, we will sum total lessons (out of 14) and total minutes of training across lessons as primary outcome variables. One-way ANOVAs will compare conditions at post-treatment on each of these two engagement outcomes. ANOVA provides a simple and compelling tool but we will extend ANOVA results using survival analysis on lessons completed to detect training condition differences in the time points at which engagement significantly drops off.

    Throughout the 14 day training period

  • Symptoms of Depression

    Mental distress will be measured over the past two weeks using the PHQ-8 to measure depression. The PHQ-8 allows participants respond to a questionnaire asking about how often they have been bothered by any of the listed problems over the last 2 weeks. Zero is equivalent to not at all and 3 indicates nearly every day.

    From baseline to 6 weeks after (1-month follow-up)

  • Loneliness

    Loneliness will be measured using the UCLA 3-item Loneliness Scale. The UCLA Loneliness Scale allows participants indicate how often they feel the way described in each of the 3 statements using a 4-point scale that ranges from 1 never to 4 always. The scoring is continuous.

    From baseline to 6 weeks after (1-month follow-up)

  • Anxiety

    Mental distress will be measured over the past two weeks using the GAD-7 to measure anxiety. The GAD-7 allows participants to respond to a questionnaire asking about how often they have been bothered by any of the listed problems over the last 2 weeks. Zero is equivalent to not at all and 3 indicates nearly every day.

    From baseline to 6 weeks after (1-month follow-up)

  • Perceived Stress

    Mental distress will be measured over the past month using the Perceived Stress Scale to measure stress. The Perceived Stress Scale measures the degree to which situations in one's life are appraised as stressful during the last month. Zero is equivalent to never and 4 indicates very often.

    From baseline to 6 weeks after (1-month follow-up)

Secondary Outcomes (6)

  • User Satisfaction

    From enrollment to the end of treatment at up to week 6

  • Mean trait mindfulness as assessed by the Toronto Mindfulness Scale-Trait

    From enrollment to the end of treatment at up to week 6

  • State Trait Mindfulness Scores

    Throughout the intervention (up to 3 weeks)

  • Self-efficacy for practicing meditation or stress management

    From baseline to 6-weeks (1 month follow-up)

  • Concentration, Sensory Clarity, and Equanimity

    From enrollment to the end of treatment at up to week 6

Study Arms (3)

Feature-Enhanced Equa Training

EXPERIMENTAL

Participants will complete a 14-day smartphone-delivered training program consisting of guided lessons through the Equa application. During lesson participation, physiological data will be collected using smartphone sensors to characterize participant responses during training activities. Participants assigned to this program version will receive additional in-app features designed to provide personalized information related to lesson engagement or training progress following lesson completion.

Behavioral: Feature-Enhanced Equa Training Program

Standard Equa Training Program

ACTIVE COMPARATOR

Participants will complete a 14-day smartphone-delivered training program consisting of guided lessons delivered through the Equa application. During lesson participation, physiological data will be collected using smartphone sensors to characterize participant responses during training activities. This program version provides the standard lesson experience within the application without additional personalized feedback features following lesson completion.

Behavioral: Equa

Stress Management Training Program

ACTIVE COMPARATOR

Participants will complete a 14-day smartphone-delivered training program focused on stress management and well-being skill development delivered through the Equa application. Lessons emphasize the development of evidence-informed coping skills, including thoughtful reflection, cognitive reappraisal of stressful experiences, and structured problem-solving strategies aimed at supporting adaptive responses to everyday stressors. Guided lessons are delivered through the same application interface and include comparable levels of interactivity and engagement activities as other study programs.

Behavioral: Stress Management Training

Interventions

EquaBEHAVIORAL

Participants will be randomly assigned to a 14-unit smartphone meditation program group that involves completing a 2-10 minute daily guided practice on their phones. Participants complete 14 units of mindfulness meditation curriculum that consists of learning and practicing techniques to improve concentration, sensory clarity, and equanimity (Equa meditation app). Physiological measures will be tracked throughout the duration of lessons.

Standard Equa Training Program

The CC program, called R\&R, is a well matched and previously validated digital stress management training. R\&R program lessons will focus on the development of three coping effectiveness skills: (a) thoughtful reflection; (b) reappraisal and reframing past and anticipated stressful events; and (c) problem solving, such as analyzing and solving personal problems.

Stress Management Training Program

Participants will be randomly assigned to complete a 14-unit smartphone-delivered guided training program consisting of brief daily lessons lasting approximately 2-10 minutes. Lessons are delivered through the Equa mobile application and focus on the development and practice of mindfulness skills designed to support concentration, awareness, and emotional well-being. Physiological data will be collected during lesson participation using smartphone sensors to characterize participant responses during guided activities. This program version includes additional in-app features designed to provide personalized visual information following lesson completion.

Masking Details
A psychometrician and statistician on our team who will remain blind to participant study condition during data collection and analysis. All study investigators/staff will be blinded to condition assignment until randomization occurs; at this time only the participant and the project manager will be aware of participant's study condition. All other study personnel will remain blinded and conduct all remaining study assessments.
Purpose
BASIC SCIENCE
Intervention Model
PARALLEL
Model Details: Investigators will evaluate whether differences in digital training program features are associated with changes in user satisfaction, engagement, and psychological outcomes. Participants will be individually randomized using a stratified 2:2:1 allocation sequence to one of several matched 14-day app-based training programs delivered through the Equa platform. Programs are comparable in branding, lesson length, platform navigation, and user experience, and include guided daily lessons focused on stress management and well-being skill development. During lesson participation, physiological data will be collected using smartphone sensors to characterize participant responses during training activities. Some program versions include additional in-app features designed to provide personalized information or feedback following lesson completion. Comparisons across program versions will evaluate usability, engagement, and changes in psychological well-being.
