Brief Summary

This primary object of this study is to test to the hypothesis that the both the nudge and boost messages will increase short term gym utilization relative to the control condition but that only the boost message will increase long-term gym utilization. Non-technical summary: College students will receive one of three messages about exercise. Their card swipe data as a measure of gym utilization will be tracked as an assessment of the effect of those messages.

Control

EXPERIMENTAL

Participants will fill out a brief Qualtrics survey which will expose them to one of three message conditions. The control group will read only summary information about the David Pottruck Health and Fitness Center.

Behavioral: Message

Boost Message

EXPERIMENTAL

Participants will fill out a brief Qualtrics survey which will expose them to one of three message conditions. Those in the Boost condition will also have summary information about the Pottruck gym but will also be given information about why an implantation intention is an effective way to attain long term goals. They will also be given a prompt to form an implementation intention.
