Abstract
In collaboration with Vitality/Discovery, we will conduct an RCT among Vitalitydrive customers. We will compare the effectiveness of fixed vs. contingent incentives, feedback vs. no feedback on driving quality, and simple vs. complex feedback formats. To inform the trial, we will also conduct secondary analyses of existing Vitalitydrive client data. We will randomize a stream of new Vitalitydrive customers who elect to install the DQ-Track device to one of three arms. We interpret differences in driver behavior across these arms as evidence for the role of played by incentives and feedback on driver risk-taking.

Interventions

Intervention(s)
Intervention (Hidden)

Participants are randomized to one of three arms:

1. Fixed incentive with driving feedback: Customers in this arm will have the DQ-Track device installed, but will be instructed that, as a part of a special offer they will receive a fixed amount (400) DP Points for the first three months of the program regardless of their driving behavior. Essentially, we will pay these customers to use the device but will not link their fuel spend cash back amount to driving data. We have set the fixed points amount at 400 to ensure high customer satisfaction -- this is approximately 120% of the median number of driving points currently earned. Customers can earn additional points by engaging in various other driving safety and awareness programs. Like typical customers, customers in this group would receive monthly email notification. Monthly email notification for this arm would include the fixed DQ points, and information about driving events and behaviors (not translated into DQ points). After the end of the trial period, these customers will revert to the existing rewards program.
2. Fixed incentive with no driving feedback: This arm of the study would randomize customers into a treatment identical to Arm #1, except that customers will not receive feedback on driving performance in their monthly email notification. A comparison of the first arm to this arm will permit us to understand the effect that feedback alone may have on driver behavior (abstracted from the reward incentives).
3. Existing Program (Control): Customers in this arm would be entered into the program as it is currently planned to be implemented i.e., with immediate feedback and incentives.

In addition, participants in each arm will be randomized to two different communications conditions, in which the monthly feedback email is in either a "loud" (high salience, simplified) or a "soft" (lower salience, more complex) format.

Primary Outcomes

Primary Outcomes (end points)
Primary Outcome Measure:

Driver Performance Score

Secondary Outcome Measures:

Harsh driving events

Claims and collisions

Primary Outcomes (explanation)

Driver Performance Score: The DQ Track device installed in the participants car records driver safety, which is rolled up into a monthly Driver Performance Score.

Secondary Outcome Measures:

Harsh driving events: The DQ Track device records each harsh acceleration, harsh braking, harsh cornering event. These are rolled up into a daily count.

Claims and collisions: We will measure any collisions or claims made on the insurance policy.
