Summary:
This report describes the affect of using different survey modes on the measurement of substance use prevalence figures. Three different modes were included in the design of this study: a telephone, a postal, and a face to face survey-mode. The study has been conducted in three European countries: Greece, Sweden and the Netherlands. These countries were selected because they recently conducted a national study on drug use, which laid the foundation for the face-to-face section of this study.
