10 Clinical Trials for Various Conditions
This randomized controlled trial will evaluate an intervention that provides parents with objective feedback about their teen's driving as well as strategies to improve communication with their teen about driving. We will recruit 180 newly-licensed teen drivers and a parent or guardian. Our main hypotheses are that: parent-teen dyads who receive feedback will have reduced driving errors and increased safety behaviors than dyads with no feedback; and, parent-teen dyads who receive instruction on communication techniques will have improved quality and quantity of communication about driving than dyads not learning these techniques.
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.
This research study examines the feasibility of using an in-vehicle mobile technology monitoring system to measure teen secondary task engagement during on-road driving as the outcome measure for a web-based intervention to prevent risky driving in novice teen drivers.
The specific aim of this study is to assess the feasibility of a web-based intervention to prevent risky driving with teen drivers licensed in the previous 90 days.
We hypothesize that this intervention will increase the quality and quantity of parental interaction on safety driving with newly-licensed teen drivers. 250 parent/teen dyads will be individually randomized into intervention and control groups. The intervention group will receive a tailored, in-person intervention with a trained member of the research team, with follow-up intervention phone calls each month for the 3-month intervention. The control group will be a "usual care" group who will receive driving safety materials available to all new drivers and their parents. Parents and teens will be followed to see if intervention parents meet the intervention's driving goals and to see if the parent and teens report improved driving skills and behaviors in the intervention compared with the control group.
Background: * Automobile crash risks are highest right after licensure and decline rapidly for about 6 months and then gradually for years, regardless of the amount of supervised practice driving or age at licensure. The only approaches to this problem that have demonstrated effectiveness are Graduated Driver Licensing (GDL) and parental management. * The Checkpoints Program consists of persuasive messages and materials designed to increase adoption of the Checkpoints Parent-Teen Driving Agreement and to improve parents' ability to set limits on higher-risk driving privileges for novice drivers. Researchers are interested in determining whether expanding the Checkpoints Program to an online version (instead of through the mail) can help improve parent limit-setting in connection with the program. Objectives: * To determine the feasibility and effectiveness of conducting an online version of the Checkpoints Program through American Automobile Association (AAA) clubs. * To test rates of parental intervention and limit-setting after participation in the Checkpoints Program. Eligibility: - Parents whose teenage children are enrolled in AAA-affiliated driving schools. Design: * Parents with children at the permit stage of driver's education will be recruited through AAA clubs and will be asked to visit a designated Web site to sign up for the program. * Parents will provide consent and complete the baseline survey, and will be assigned to random groups to test different versions of the Checkpoints Program (the intervention or a control group Web site). * The intervention program will contain videos, regular e-mails, and newsletters on setting parental limits and information on specific teen driving risks. The control program will provide information on various topics related to the licensing procedure and safe driving, but no specific information on teen driving risks. * A follow-up assessment will be conducted 1 month after the teenager receives his or her license.
To determine the effectiveness of four group session of motivational counseling plus six hours of direct observations of the emergency department trauma services in comparison to four group session and six hours of community volunteering and also in comparison to four hours of education and 16 hours of community volunteering in reducing alcohol use and high risk driving behaviors and offenses among court referred 16-20 year old drivers.
This study, conducted at the University of Massachusetts at Amherst, will examine how male teenage driving performance varies in the presence or absence of male teenage passengers. It will explore what information teen drivers and their passengers use when making decisions that affect their performance on the road. Male drivers under 18 years of age who have a Junior Operator's or Full License and have driven at least once in the month before enrolling in the study may be eligible to participate. In a university laboratory, participants sit in a 1995 Saturn sedan and operate the controls of the car just as they would those of any other car, during simulated drives in urban, suburban and rural areas. They are fitted with a head-mounted eye tracker that records their point of gaze in real time. On one drive, the subject drives alone; on another, a male passenger rides along. After the drives, the subject fills out some questionnaires.
This study will evaluate the driving performance of new teenage drivers and determine to what extent independent driving experience improves driving performance of young drivers. Motor vehicle crash rates are highest among new teen drivers, especially during the first 6 months and 1,000 miles of independent licensed driving. Crash rates decline with experience, and this study will assess the effect of driving experience on performance. Newly licensed teenagers ranging from 16 years, 3 months to 17 years of age and experienced drivers 30 to 50 years of age may be eligible for this study. Candidates must be able to legally drive in the commonwealth of Virginia and have at least 20/40 correctable vision. Participants complete a questionnaire about their health and driving experience. They are then tested on a driving test track. Teens are tested within 3 weeks of obtaining their driver's license and before they have more than 100 miles of independent driving experience. They are tested a second time 6 to 12 months later and after they have more than 1,000 miles of driving experience. A group of experienced adult drivers are also tested to provide a comparison. The driving test is conducted on a smart road - a controlled, 2.2-mile two-lane research track at the Virginia Tech Transportation Institute. It is designed for safety, with restricted access, nothing for a vehicle to hit, carefully placed guardrails, and other safety features. The research vehicle is equipped with airbags, anti-lock brakes, and other safety equipment. It also has sensors and tiny video cameras to assess the behavior of the vehicle and the driver; this equipment does not interfere with the operation of the vehicle. An experimenter accompanies the driver and instructs him or her to perform routine driving skills, such as stopping, changing lanes and maintaining speed, as well as to other tasks such as inserting a CD into an entertainment console, having a conversation, and answering a cellular telephone call. The driver has an opportunity to practice the tasks before being tested. The driver's speed is limited to 35 mph or less during the experiment and the driver is required to wear seat belts and follow safe driving procedures. The experimenter is in the front passenger seat can stop the vehicle using a separate brake pedal.
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 then be randomly assigned to one of four conditions: education only (control), opt-in blocking, opt-out blocking, and opt-out blocking with parental notification.
