This paper reports on the results of surveys of the media usage by two small groups of students, one group in New York City and the other in Los Angeles. The voice and data traffic implications of the results are estimated. When converted to bits, the telephone traffic was much greater than the data traffic. An attempt is made to reconcile the findings with network usage data that implies that ...

BACKGROUND Telephone surveys based on samples of landline telephone numbers are widely used to measure the prevalence of health risk behaviours such as smoking, drug use and alcohol consumption. An increasing number of households are relying solely on mobile telephones, creating a potential bias for population estimates derived from landline-based sampling frames which do not incorporate mobile...

In this chapter, we examine what has been written about Internet surveys in the literature, specifically Web and e-mail surveys. We address the topics of response rate, cost, timeliness, sources of error, and data quality.1 We compare two conventional survey modes, mail and telephone, with Internet survey modes. The other widely used conventional mode, face-to-face interviewing, is not addresse...

BACKGROUND Primary care has long been of interest to policy research. Recently, there is evidence to suggest that it is becoming more difficult to encourage GPs (general practitioners) to participate in surveys. As low response rates can introduce bias into survey results, it is important to study the effects of non-response. AIM To assess the validity of a response rate of 44% obtained in a ...

BACKGROUND Persons with a mental health diagnosis have high rates of tobacco use and face numerous barriers to cessation including high levels of nicotine dependence, low rates of tobacco treatment referrals from mental health providers, and limited availability of tobacco treatment targeted to their needs. This manuscript describes the rationale and methods of a clinical trial with the followi...

Surveys by the Addiction Research Foundation of Ontario have produced annual estimates on smoking prevalence since 1991. This report describes the three series of telephone surveys from which these data are drawn as well as future plans to monitor tobacco use in Ontario. In addition to provision of updated descriptive results, the methodology and limitations of the data are discussed. Prevalenc...

Health behaviors are a leading cause of illness and death in the United States. Efforts to improve public health require information on the prevalence of health behaviors in populations - not only to target programs to areas of most need but also to evaluate the effectiveness of intervention efforts. Telephone surveys, such as the Centers for Disease Control and Prevention's Behavioral Risk Fac...

BACKGROUND Non-coverage of households without a landline telephone is a major concern of telephone survey researchers. Sampling mobile telephone users in national surveys is vital in order to gain access to the growing proportion of households that use mobile telephones extensively or exclusively. The complex logistics of conducting surveys with mobile telephones have been discussed in the lite...
