The study documents the use of the Internet by Quebec dietitians, and addresses their specific needs according to their fields of practice. Of the 1,852 questionnaires mailed, 708 were returned. Most of the respondents have a computer at home or at work, and have access to the Internet. The Internet is used mostly at home. Factors limiting greater use of the Internet include time, knowledge and cost. The most popular services are electronic mail and the World Wide Web. Most of the respondents would be interested in training programs on database searches, on searching for information on the Internet and on evaluating the validity of information found on the Internet. Data analysis has revealed that Internet usage is related to dietitians' fields of practice. Moreover, specific training needs have been identified for clinical dietitians, dietitians in private practice and in public health, and those combining managerial and clinical activities. Results suggest the need to adapt training programs and services to dietitians' fields of practice and to develop these programs accordingly.
