Study Overview
Brief Summary
The purpose of the study is to determine the efficacy of a smartphone app in reducing mobile phone use while driving among teens and parents. Prior to sending a message, the smartphone app informs a potential message sender that the recipient is driving.
Detailed Description
The primary objective of this study is to determine whether the app reduces (1) smartphone communication sent from parent to teen while the teen is driving; and (2) smartphone communication sent from teen while the teen is driving. The secondary objectives are to: Determine whether the app reduces smartphone communication sent from teen to parent while parent is driving; Evaluate the acceptability of the app among parents and teens; and determine the relationship between individual differences (demographics, typical smartphone use, driving history, risk perception) and the app's efficacy.

Masking Description
Participants will be randomly assigned to the intervention/Bluetooth group, intervention/non-Bluetooth group, control/Bluetooth group, or control/non-Bluetooth group upon enrollment in the study. Assignment status will not be concealed from the research assistants enrolling the participant, the participants themselves, or the rest of the study team.

Arms & Interventions
Control Bluetooth
Participants receive a the same app as the intervention group, but the feature that notifies the teens parent when they are driving is turned off. They will self-report their smartphone communication while driving via periodic surveys. Participants will receive a Bluetooth device to keep in their primary vehicle for the duration of the study.
Intervention: Control Bluetooth (Other)
Intervention Bluetooth
Participant received the app with all features turned on, so the parent gets a notification when the teen is driving before they go to send a text message to the teen. They will self-report their smartphone communication while driving via periodic surveys. Participants will receive a Bluetooth device to keep in their primary vehicle for the duration of the study.
Intervention: Intervention Bluetooth (Other)
Control non-Bluetooth
Participants receive a the same app as the intervention group, but the feature that notifies the teens parent when they are driving is turned off. They will self-report their smartphone communication while driving via periodic surveys. Participants will not receive a Bluetooth device.
Intervention: Control non-Bluetooth (Other)
Intervention non-Bluetooth
Participant received the app with all features turned on, so the parent gets a notification when the teen is driving before they go to send a text message to the teen. They will self-report their smartphone communication while driving via periodic surveys. Participants will not receive a Bluetooth device.
Intervention: Intervention non-Bluetooth (Other)
Outcomes
Primary Outcomes
Changes in frequency of smartphone use while driving
Time Frame: 3 weeks
Changes in smartphone communication sent from parent to teen while the teen is driving and changes in smartphone communication sent from teen while the teen is driving. Frequency of smartphone use is recorded by the app among the three app modes. Within-driver smartphone use over the 3-week study period is compared as the app modes change. Smartphone use between driver groups will also be compared.
Secondary Outcomes
- Changes in frequency of self-reported smartphone use while driving(3 weeks)
- Changes in frequency of text messages sent to Bluetooth device users(3 weeks)
- Acceptability and Usability of the App(3 weeks)
