PRACTICE Pike / MEASURING VIDEO GAMBLING Measuring Video Gambling: Instrument Development and Validation

Objective: This article reports the initial validation of an instrument designed to measure problem gambling on video gambling devices. Methods: Two samples were collected and included: • individuals at random lists of playing locations for all counties in one state (n = 553) • a general public sample also drawn from each county (n = 542). Results: The scales attained high levels of internal consistency reliability and had a stable factor structure. The items predicted with high accuracy pathological and non-pathological gambling, and the scales performed well in examinations of discriminant and convergent construct validity. Conclusions: The research provided strong evidence of internal consistency reliability, as well as content, construct, factorial, and preliminary evidence of known-groups validity.
