- 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.

Group Intervention Description Control Bluetooth 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. Control non-Bluetooth 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 non-Bluetooth 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.

- Primary Outcome Measures
Name Time Method Changes in frequency of smartphone use while driving 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 Outcome Measures
Name Time Method Changes in frequency of self-reported smartphone use while driving 3 weeks The change in self-reported smartphone use while driving will be assessed using the same within-driver and between-driver comparisons as the primary outcome measure. Self-reported smartphone use is collected through 10 items on a participant survey that is completed at enrollment, each week for 3 weeks. Participants also report how many times per day (free text, any number greater than or equal to 0) that they drove, and talked on a hands-held smartphone, sent a text, and read a text while driving.
Changes in frequency of text messages sent to Bluetooth device users 3 weeks Bluetooth device users will have received text message date and time collected via the Bluetooth device. This device will only collect data from the dyad partner enrolled in the study with them. This data will be used to validate the self report data collected from all participants.
Acceptability and Usability of the App 3 weeks Participant assessment of accessibility and usability will be collected, and Manual Mode and Auto-Detect Mode of the LifeSaver app will be compared. Participants complete a survey at the end of week 3, post-intervention. 8 items in the survey ask participants about accessibility and usability of the app through Likert scales (range from Not at all to Extremely). 3 items in the survey ask participants about accessibility and usability of the app through open-ended questions, where participants are able to enter free text. There is no overall score for these survey items.
