Brief Summary

Research participants and their parents will be recruited to take part in a randomized control trial. Participants' and their parents' cellphone use will be observed during an initial baseline period. Participants and their parents will then be randomly assigned to one of two conditions: opt-out blocking with parental notification, opt-out blocking with bidirectional notification.

Detailed Description

In 2012, 3,328 people were killed and an additional 421,000 were injured in crashes involving a distracted driver. Adults aged greater than 40 years old accounted for 44% of these fatalities. Teen driving behavior is heavily influenced by parental driving behaviors with a recent study showing the proportion of teens that text while driving is 14% higher if they have observed their parents doing the same. The proportion of adults who text while driving has recently surpassed teen rates with a 2013 national poll finding 49% of adult car commuters admit to texting while driving, most stating that they did it out of habit. Based on previous findings, it is unlikely that teens will reduce their texting while driving unless their parents do the same.

The objective of this study is to compare measures of acceptance and feasibility across teen-parent dyads randomized to bidirectional teen-parent (teen monitors parent and parent monitors teen) vs. teen only (parent monitors teen) cellphone use while driving.

Research participants will be recruited to take part in a randomized control trial. Participants' cellphone use will be observed during an initial baseline period. Participants will be randomly assigned to one of two conditions (bidirectional teen-parent monitoring or parental monitoring of the teen only). An exit survey and interview will be administered to both the parent and teen separately at the end of the study.

Study Groups

Teen-Parent Monitoring Group

Cellcontrol DriveID device will automatically turn on when the teen or parent begins driving and will be pre-set to block all calls and text messages when the car is in motion but participants will have the ability to override the blocking. The teen-parent monitoring group involves will send email notifications to the teen when their parent unlocks their phone while driving and vice versa.

Participants (parents and teens) will self-report information on their individual driving behaviors for the three weeks prior to study enrollment, including how often they report texting while driving and self-report cellphone use. At the end of the study participants will be asked to report feedback about the use the cellphone blocking technology and their perceptions for whether their safety improved using the technology.

Group Type: EXPERIMENTAL

CellControl

Intervention Type: DEVICE

Technology that blocks incoming and outgoing calls and texts. CellControl Drive ID will monitor all cellphone use while driving (without blocking) for 3 weeks during baseline measurement period. During the intervention period (5 weeks) cellphone use will be monitored and blocking of incoming calls and texts will be active.

Teen Only Monitoring Group

Cellcontrol DriveID device will automatically turn on when the teen or parent begins driving and will be pre-set to block all calls and text messages when the car is in motion but participants will have the ability to override the blocking. The teen only group involves parental monitoring of the teen's cellphone use while driving only. The parent will receive an email notification when their teen unlocks their phone while driving. Both parents and teens will drive under the same restrictions, but only the parent is notified of teen cellphone use.

Participants (parents and teens) will self-report information on their individual driving behaviors for the three weeks prior to study enrollment, including how often they report texting while driving and self-report cellphone use. At the end of the study participants will be asked to report feedback about the use the cellphone blocking technology and their perceptions for whether their safety improved using the technology.

During the intervention period (5 weeks) cellphone use will be monitored and blocking of incoming calls and texts will be active.
