1. SBU = Safety belt use
2. Single Measure of Safety Belt Use = Respondents were asked the following question: "Think about the times you've ridden in a car in the past 30 days. Overall, how often did you wear a seatbelt?" The overall outcome of analysis, safety belt use, was determined by the frequency of participants that answered 'always' on this question.
3. Multiple Measure of Safety Belt Use = Respondents were asked a series of situation-specific transportation questions (highway travel, local road travel, daytime travel, travel at night, driving a car, front seat passenger, back seat passenger, short trips of 10 minutes or less, and trips longer than 10 minutes). We classified safety belt use via the Multiple Measure as a response of 'always' to all nine scenarios.
