Brief Summary
The purpose of this study is to evaluate the effectiveness of a program designed to reduce
teen crashes and risky driving by increasing parental monitoring and restriction of their
adolescents' driving practices during the first year of licensed driving.
Detailed Description
Motor vehicle crashes are the major cause of death and disability among adolescents from 16
through 20 years of age. While adolescents between the ages of 16 and 19 years constitute
only 5% of all licensed drivers, they are involved in 15% of the crashes in which they or
other occupants are killed. In fact, 16-year-old drivers are more than 20 times as likely to
have a crash as the general population of drivers and 17-year-olds are more than 6 times as
likely. In addition, for each adolescent motor vehicle fatality, approximately 100 nonfatal
injuries occur, making crashes the leading cause of disability due to head and spinal cord
injuries in adolescents.
Parents can have a huge impact on adolescent behavior. However, the impact of parenting
practices on adolescent driving behavior has not yet been examined. This study aims to
determine the efficacy of an intervention designed to increase parents' involvement in, and
parental restrictions on, their teens' early driving experiences in order to reduce the
number of tickets and crashes among teen drivers. The intervention provides educational
materials to parents and adolescents from the time the adolescent gets a learner's permit
through the first 6 months of licensure. These persuasive communications are tailored to
adolescents' level of driving experience. The intervention materials make explicit the
increased risk associated with adolescent driving and methods for reducing risk through
increased parental involvement in and restriction of driving.
Participants were recruited in the Connecticut Department of Motor Vehicle offices as
adolescents applied for their learner's permits. Participants were randomized to either the
intervention group or the control group. The control group received standard information
about driving not related to the specific teen risks focused on in the intervention group
materials. All participants completed interviews at study entry, licensure, 3 months after
licensure, 6 months after licensure, and 12 months after licensure. Parents were asked about
their expectations and parenting practices regarding their adolescents' driving behaviors.
Adolescents were asked about their driving practices and their parents' rules and
restrictions regarding driving. The driving records for each adolescent were obtained from
the state motor vehicle administration and examined 18 months after licensure.

Conditions
Conditions usually refer to a disease, disorder, syndrome, illness, or injury. In ClinicalTrials.gov,
conditions include any health issue worth studying, such as lifespan, quality of life, health risks, etc.
Interventions
Interventions refer to the drug, vaccine, procedure, device, or other potential treatment being studied.
Interventions can also include less intrusive possibilities such as surveys, education, and interviews.
Study Phase
Most clinical trials are designated as phase 1, 2, 3, or 4, based on the type of questions
that study is seeking to answer:
In Phase 1 (Phase I) clinical trials, researchers test a new drug or treatment in a small group of people (20-80) for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
In Phase 2 (Phase II) clinical trials, the study drug or treatment is given to a larger group of people (100-300) to see if it is effective and to further evaluate its safety.
In Phase 3 (Phase III) clinical trials, the study drug or treatment is given to large groups of people (1,000-3,000) to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
In Phase 4 (Phase IV) clinical trials, post marketing studies delineate additional information including the drug's risks, benefits, and optimal use.
These phases are defined by the Food and Drug Administration in the Code of Federal Regulations.
