Study Summary

Rationale: Mindfulness is a popular therapeutic strategy that has a growing body of evidence suggesting it can improve a wide range of physical and psychological symptoms. Yet, confusion exists as to why mindfulness is effective as well as the most effective ways in which to teach and practice mindfulness. The present study will test a mindfulness training protocol to better understand the most effective ways to teach and practice mindfulness. Intervention: A group of video game players, or "gamers", will be instructed on how to play a video game of their choice in a more mindful way and compare this to an activity of daily functioning (i.e., folding laundry). Outcomes from self-report measures taken both before and after study activities will be tested against a control group of gamers who will perform the same study activities without the mindfulness induction. Objective or Purpose: The purpose of the present study is to test the effects of a brief, standardized mindfulness prompt in order to better understand effective ways to train mindfulness concepts. The mindfulness prompt will be applied to an intrinsically motivated activity (i.e., video game play for experienced gamers) and an activity of daily functioning (i.e., laundry folding) in order to evaluate the different effects of mindfulness practice when implemented with a popular leisure activity versus a less engaging activity of daily living. Study Population: This study will include adult "gamers" ages 18-65. A gamer is someone who engages in some form of digital video game play for a minimal average of three hours per week. A pre-screening measuring will rule out any participants who do not play video games with enough frequency to be considered a gamer. Study sessions will take place remotely overseen via a Zoom-based video call with study personnel. Another exclusion criteria will be an inability to speak with study personnel via Zoom or do not have a private area to perform the study activities.

Primary Outcome

The Positive and Negative Affect Schedule is a 5-point Likert scale with a minimum value of "1" (very slightly or not at all) and a maximum value of "5" (extremely). The Positive and Negative Affect Schedule measures participants' emotions/affect in the present moment. For this study the Positive and Negative Affect Schedule will be administered prior to and then immediately following a study activity and the change score from pre- to post-activity will constitute a primary outcome.
