Brief summary
The purpose of this study is to measure the effects of an interactive video on adolescent risky behaviors and outcomes, with one video intended to reduce teen pregnancies and the other intended to reduce automobile accidents.
Detailed description
Motor vehicle crashes cause one-third of teenage deaths and many serious injuries. Teen drivers ages 16 to 19 are four times more likely than older drivers to crash. Death and injuries could be reduced with a change in behaviors that include improved visual and attention skills while driving, more seat belt use, appropriate speed control, and not combining drinking or texting with driving. Sexually transmitted infections (STIs) and unplanned pregnancies are particularly common among adolescents. The U.S. adolescent birthrate is by far the highest among industrialized nations. These problems can be decreased by less sexual activity and better protection. This study uses a randomized controlled trial to measure how well interactive video interventions can reduce these common risks to adolescents. Adolescent females will be invited to participate if they are currently seeking care at a participating clinic. They will answer survey questions about their driving and sexual behaviors, and then a computer will determine whether they will be given a video about driving or a video about sexual behavior. Participants will have unlimited access to their video, which they can watch at their clinic or from any Internet-enabled computer, and will be followed for 6 months.
Interventions
BEHAVIORALSeventeen Days

BEHAVIORALDriving Skills for Life
Interactive video includes guidance and practice for safe driving techniques, driver and car care tips, an eco-driving learning module, and interactive driving games.

Outcome results
Primary
Perceived Self-efficacy for Condom Use
To assess the effects of the Seventeen Days interactive video on young women's perceived self-efficacy for using condoms 6 months after being offered the intervention, relative to a control.
Time frame: 6 months
Population: Sexually active female adolescents ages 14 to 19 years. The overall number of participants analyzed are those that completed the baseline survey, video component and the 6 month survey.
| Arm | Measure | Value (MEAN) |
|---|---|---|
| Sexual Behavior Intervention | Perceived Self-efficacy for Condom Use | 13.00 summation score |
| Driving Behavior Intervention | Perceived Self-efficacy for Condom Use | 12.48 summation score |
Comparison: Summation scores are reported across 3 items measured on a 5-point scale from 1(not at all sure)to5(very sure), which loaded together on a principal components analysis of the baseline data.The summation score thus represents a theoretical range from 3 to 15.The 3 items were as follows:Indicate How Sure You are that You Would be Able to Perform Each of the Following:a)Get the money needed to buy condoms b)Walk into a store\&buy condoms c)Find a place to get condoms for free(Cronbach alpha-0.72)95% CI: [3, 15]
