  1. Monitoring trends in drug use : Strategies for the 21st century.

    Article - En anglais

    Since the 1970s the United States and other nations have conducted regular statistical monitoring of the prevalence and patterns of drug use in their populations.

    Given the importance of such surveys for policymaking, their quality is a critical issue, and the biases that may affect their measurements become a major concern.

    An increasing volume of empirical evidence shows that the mode of administration of a survey can strongly influence the validity of respondents'reports.

    Compared with interviewer-administered questionnaires, self-administered forms appear to elicit more complete reporting of drug use, but the challenges they pose to the literacy skills of respondents may result in measurement biases.

    In addition, processes of social change may confound true shifts in drug use with changes in the willingness of respondents to report such use.

    The authors propose several strategies to improve monitoring of trends in drug use.

    Those approaches include 1) more frequent use of a survey technology-audio computer-assisted self-interviewing-that ensures full privacy for all survey respondents but does not require literacy ; 2) increased use of time-series of indicators of drug use consequences built from blinded surveys of medical records ; and 3) population-based surveys that collect biological specimens (e.g., hair samples).

    Data from the latter two sources are not subject to the same constellation of biases that afflict self-reports of drug use. (...)
