Development of Virtual reality based assessment for craving: reliability and validity

Purposes: Self-report scales was often utilized to assess the severity of craving in past. Despite it is time-effectiveness, the reliability was confounded by memory bias and social desire. Therefore, virtual reality based instrument is necessary to reduce the limitation of self-report scale. Until now, little study was to develop virtual reality instrument and examine its reliability and validity in past. Hence, this study will develop a standardized virtual reality based instrument to induce craving.
