Effect of adding a virtual community (bulletin board) to smokefree.gov: randomized controlled trial.

Background: Demand for online information and help exceeds most other forms of self-help. Web-assisted tobacco interventions (WATIs) offer a potentially low-cost way to reach millions of smokers who wish to quit smoking and to test various forms of online assistance for use/utilization and user satisfaction.

Objectives: Our primary aim was to determine the utilization of and satisfaction with 2 versions of a smoking cessation website (smokefree.

A review of web-assisted tobacco interventions (WATIs).

Background: The Internet has great potential to provide assistance to millions of smokers who seek help with quitting smoking.

Objective: The goals of this study were to assess the content and the quality of smoking cessation treatments most likely to be encountered by smokers seeking treatment on the Internet and to examine differences in quality between current websites and those reviewed in 2004.

Methods: Internet searches for smoking cessation were designed to mimic the search patterns of most Internet users.

The importance of usability testing in the development of an internet-based smoking cessation treatment resource.

It has been cogently argued that Web-based interventions hold substantial promise to deliver effective cessation to a wide audience. However, the potential effectiveness of a site is constrained by fundamental issues such as ease of navigation and structure of information, which impact a visitor's ability to find relevant information. Use of content and Web-design experts to assist in the development of cessation sites is a common approach.

Smokers who use internet and smokers who don't: data from the Health Information and National Trends Survey (HINTS).

Web-assisted tobacco interventions (WATI) have proliferated in recent years, but little is known about those such sites are reaching and those who might be reached in the future. A better understanding of factors that differentiate smokers who do and do not use the Internet could help developers of smoking cessation resources optimize the content and dissemination of resources to these two groups. Using the 2003 Health Information National Trends Survey (HINTS), a nationally representative survey of U.

Exercise training effects on premenstrual distress and ovarian steroid hormones.

Preliminary studies suggest that moderate physical activity may reduce both premenstrual distress (PD) and the ovarian steroid hormones, progesterone and estradiol, which have been implicated in PD. We attempted to replicate these findings, while exploring possible relationships between hormone levels and PD. In a cross-sectional study, 20 moderate exercisers and 34 sedentary women completed PD symptom questionnaires and collected urine samples, daily, throughout a complete menstrual cycle.

Toward evidence-based Internet interventions: A Spanish/English Web site for international smoking cessation trials.

The Internet provides a medium to administer and evaluate evidence-based interventions for highly prevalent public health problems worldwide. The authors report a series of four Internet smoking cessation studies conducted in English and Spanish. These studies examined both outcome (self-reported 7-day abstinence) and mechanisms related to outcome (the impact of major depressive episodes [MDEs] on the likelihood of quitting).

Smoking cessation research via the internet: a feasibility study.

To reverse the present stagnation in progress toward reduced smoking rates, new widely accessible treatment methods for smoking cessation must be developed and evaluated with large groups of smokers. We tested the feasibility of conducting a smoking cessation study over the Internet using a brief, self-help educational intervention. Through a direct e-mail sent from a large health information web site (WebMD), and with our presence on the Internet, we recruited 538 adult smokers to the study.
