Before beginning the daily practices, this group will be introduced to the OMI via an online platform and answer any questions about the practice. Then, each day, this group will be guided through a series of mindfulness practices offered online (www.bemindfulonline.com) delivered on their smartphones or laptops.

Before beginning the daily OMI, in addition to being briefed, this group will be paired with a peer to be in touch with and guide and support each other in this process. Then they will start the OMI program and will follow parallel instructions as the OMI group. The peer support will include five brief (30-minute) weekly meetings to support and encourage each other to continue practicing mindfulness and to complete the online intervention. Each week we will provide prompts and topics for participants to discuss and at the end of each meeting, participants will then complete a short, 5-10 minute post-meeting survey to assess the well-being and attitudes of their partner (see additional materials for meeting prompts and post-meeting survey questions). The first of these meetings will occur on Day 8, and subsequent weekly meetings during the intervention period will be scheduled based on the shared availability of both participants in each pair.

Instead of the OMI, this group will be receiving cognitive exercises in the intervention period.

This project will use a Randomized Control Trial (RCT) design and Daily Reconstruction Method (DRM8) to model the effects of the OMI on dynamic changes in first-year undergraduate and graduate students' well-being over time. The intervention will take place over the course of 46 days, with a 7- day follow up assessment taking place one month after the intervention. People will complete surveys through an online link leading to Qualtrics.com.

The FFMQ is a self-reported, instrument assessing mindfulness based on five factors that represent elements of mindfulness ( observing, describing, acting with awareness, non-judging of inner experience, and non-reactivity to inner experience). Possible scores range from 1 (never or very rarely true) to 5 (very often or always true).

The self-reported measure consists of 23 items. The health, negative emotion, loneliness, and overall happiness questions act as filler questions and provide more information; for briefness, the 15 PERMA questions (3 per PERMA domain) could be used, but we recommend using the full measure.

SF-36 is a self-reported instrument assessing easily administered quality-of-life measures which consists of 8 subscales. These measures rely upon patient self-reporting and are now widely utilized by managed care organizations and by Medicare for routine monitoring and assessment of care outcomes in adult patients.
