The 2007 MVOSS was composed of two questionnaires, each administered to a sample of randomly selected individuals 16 and older, with ages 16 through 39 over-sampled:

  • Version 1 Questionnaire focused on seat belt issues. It contained shorter modules on vehicle speed, air bags, drinking and driving, crash injury experience, and demographics.

  • Version 2 Questionnaire focused on child restraint use. It included shorter modules on seat belt use, driver education and licensing, air bags, emergency medical services, phone use while driving, crash injury experience, and demographics. Selected questions regarding seat belts, air bags, crash injury experience, and demographics appeared on both questionnaires.

The survey was administered from January 9, 2007 to April 30, 2007. A total of 5,908 respondents completed the survey using the Version 1 Questionnaire and 6,010 respondents completed the survey using the Version 2 Questionnaire. Three databases are provided:

  • Data collected by the Seat Belt Issues (version 1) questionnaire;
  • Data collected by the Child Restraint Use (version 2) questionnaire; and
  • Data from questions that appeared on both questionnaires.

The third database duplicates data from the first two databases, yet it provides approximately 12,000 cases (i.e., all participants in the survey regardless of the questionnaire version they received). The databases are provided in two formats: Statistical Package for the Social Sciences (SPSS) and Statistical Analysis System (SAS) formats.
