About this study

Official title: Comparative Effectiveness of Financial Incentives and Smartphone-based Nudges to Reduce Cellphone Use While Driving Among Auto Insurance Policy Holders With Usage Based Insurance Policies

The investigators are proposing an experiment to help a national auto insurance company test behavioral economic strategies to reduce the amount of time policy holders actively use their cell phone while driving. Interventions include financial incentives, social comparison, and nudges, and survey data will also be collected. Data collected from this internal trial will be shared with the Penn research team and analyzed

Being tested
Weekly feedback, End of intervention period incentive, Loss-framed weekly incentive

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Weekly feedbackBehavioural

    Send push notification reporting user's handheld phone use while driving compared to distribution for driver cohort (age, geographic area) each week.

  • End of intervention period incentiveBehavioural

    Notify participant about potential incentive at the end of the intervention period, but do not provide weekly feedback about performance.

  • Loss-framed weekly incentiveBehavioural

    Send push notification reporting user's handheld phone use while driving compared to distribution for driver cohort (age, geographic area) each week. Pay participant weekly according to where they fall on the distribution each week.

Social comparison feedbackExperimentalReport user's handheld phone use/ hour of driving for week. Compare this week's performance to distribution for driver cohort.

End of rating period incentiveExperimentalMonitor throughout intervention period and compare overall use to distribution for cohort. Notify participant at end of intervention period regarding the amount they have earned.
Receives: Behavioral: End of intervention period incentive
End of rating period incentive + social comparison feedbackExperimentalMonitor throughout intervention period and compare weekly phone use to driver cohort distribution. Send weekly push notification to provide feedback. Notify participant at end of intervention period regarding the amount they have earned.
Receives: Behavioral: Weekly feedback; Behavioral: End of intervention period incentive
Weekly loss-framed incentive + social comparison feedbackExperimentalMonitor throughout intervention period and compare weekly phone use to driver cohort distribution. Send weekly push notification to provide feedback. Notify participant weekly regarding the amount they have earned.
Receives: Behavioral: Weekly feedback; Behavioral: Loss-framed weekly incentive
Larger weekly loss-framed incentive+social comparison feedbackExperimentalMonitor throughout intervention period and compare weekly phone use to driver cohort distribution. Send weekly push notification to provide feedback. Notify participant weekly regarding the amount they have earned. Incentive amount is higher than "Weekly loss-framed incentive + social comparison feedback" Arm.
Receives: Behavioral: Weekly feedback; Behavioral: Loss-framed weekly incentive

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Seconds of active phone use per hour of driving

    Percentage of driving time engaging in active handheld phone use (also measured as seconds of distracted driving/hour of driving)

    Measured: 150 days

Secondary outcomes (3)
  1. Seconds of passive phone use per hour of driving

    Seconds of passive handheld, non-call use per hour of driving

    Measured: 150 days

  2. Hard breaking events per 100 miles

    notifications turned off, drop out of study, app uninstall

    Measured: 150 days

  3. Hard acceleration events per 100 miles

    Hard acceleration events per 100 miles

    Measured: 150 days
