Objective:
The Evaluation of Risks (EVAR) scale has been used to assess risk-taking propensity in military samples. This report provides preliminary reliability, validity, and normative data on a modified version of the instrument designed to facilitate data entry with optical scanners, the Evaluation of Risks-Bubble Sheet version (EVAR-B).
Methods:
2,015 U.S. Army soldiers completed the EVAR-B and a survey assessing risk-related behaviors 3 months after returning home from combat deployment in Iraq.
Results:
EVAR-B demonstrated acceptable internal consistency and reliability and correlated significantly with independent measures of self-reported risk-taking behavior, including alcohol use and aggressive behavior, in the weeks preceding the survey. Tentative cut-offs significantly differentiated heavy drinkers, dangerous drivers, and soldiers reporting recent aggressive outbursts. Normative data are provided for comparison with future studies.
Conclusions:
The EVAR-B is a reliable and valid measure of risk-taking propensity, which provides enhanced flexibility for administration and scoring in large surveys and field environments.
