Clinical Trial Summary
The purpose of the study is to evaluate, prospectively, the potential impact on myHealth
Rewards wellness program enrollment (prior to the 2020 deadline) of sending different
messages via email to Geisinger Health Plan (GHP) members who have not yet enrolled. In
particular, this study aims to replicate and extend (with greater sample size and statistical
power) the findings from a previous study in which email communication using loss framing
language achieved significantly higher click-through rates than a more standard
communication, whereas actual enrollment rates were not significantly higher.
Description:
The myHealth Rewards wellness program managed by GHP rewards those GHP members who carry
their insurance through employment at Geisinger with reduced health insurance premiums over
the course of the following year, if members register for the program and have their health
measures on file by the enrollment deadline and are then able to meet their health goals by
the respective due date. In spite of the potential savings to health plan members and the
wellness program's potential to motivate engagement in healthy activities (with consequent
improvement in health outcomes), about 23% of eligible existing GHP members did not enroll
during the primary 2019 enrollment period, even after receiving promotional email
communications and reminders.
Previous work examining myHealth Rewards found that email communication using loss framing
language achieved significantly higher click-through rates than a more standard
communication, whereas actual enrollment rates were not statistically significantly higher.
The current study aims to analyze de-identified Geisinger Health Plan (GHP) member data,
comparing enrollment status (and secondarily, click-through rates) within the 2020 enrollment
period across email conditions to which GHP members will be randomly assigned. The main part
of this study will compare the effects of a standard, generic communication vs. communication
with loss framing, using a larger sample size for adequate statistical power to detect the
original difference in enrollment rates as significant, should that difference be real and
reliable. Additional conditions are added after this main comparison in order to compare more
precisely other pairs of communications conceived in the original study.
The generic email condition will consist of a standard email of the kind that would typically
be sent by GHP to encourage enrollment, which includes the average amount saved, the ease of
registration, and a reward incentive. The loss framing condition will highlight that
respondents are forfeiting savings unless they take action and register. The two testimonial
conditions will have a testimonial from a doctor (medical expert condition) or a customer
care specialist (rank-and-file condition) about how the program helped them. The two social
norms conditions will show the percentage (percentage condition) or number (number condition)
of fellow Geisinger members who already signed up. Emails will go out in three waves. For
each wave, Geisinger employees who have not already registered at that time will be
randomized into one of two groups:
Wave 1: generic email vs. loss framing email
Wave 2: testimonial (expert) vs. testimonial (rank-and-file)
Wave 3: social norms (percentage) vs. social norms (number)
It is hypothesized that, on average, the loss frame email will increase enrollment compared
with the standard email. The other comparisons are exploratory and do not have a priori
hypotheses. Findings will help inform how best to increase enrollment in a wellness program
through email communication.
