|Samenvatting||The present study was conducted within Work Package 2 (Epidemiology) of the EU-funded project DRUID (Driving under the influence of drugs, alcohol, and medicines) in order to estimate the prevalence of psychoactive substances within the German driver population and to identify preventive and promotive circumstances of drug driving. The results serve as major input to the discussion on drug driving, rehabilitation, and prevention. The final sample consists of 195 drug users and 100 controls out of the normal driving population, stratified for sex, age (18-24-year-olds, 25-29-year-olds, and 30-39-year-olds), and residence (rural, urban, and city area). To capture real-time data about drug consumption and driving, a repeated-entry diary technique was applied. A questionnaire was installed on smartphones and was filled in daily for 28 consecutive days. All activities were listed in chronological order. The synchronisation of the reported information about drug use and driving enabled the identification of drives under influence. Furthermore, an extended diagnostic part was included in the study to gather person-related driver characteristics (e.g. socio-demographic information, relevant previous experiences, major mental diseases, psychometric performance measures, personality variables, information about the social context, attitudes, knowledge about legislation, and information about the subjective sanction severity). Prevalence rates estimated by the survey results of the present study and identified situational factors of drug driving were reported in Walter, Hargutt and Krüger (2011). The methodological procedure is also described there. This report focuses on person-related factors of drug driving, i.e. the characteristics of drug impaired drivers.
