J Med Internet Res 2007 (May 09); 9(2):e11

HTML PDF XML Abstract

Background: Research increasingly supports the conclusion that well-designed programs delivered over the Internet can produce significant weight loss compared to randomized controlled conditions. Much less is known about four important issues addressed in this study: (1) which recruitment methods produce higher eHealth participation rates, (2) which patient characteristics are related to enrollment, (3) which characteristics are related to level of user engagement in the program, and (4)...

Following Up Nonrespondents to an Online Weight Management Intervention: Randomized Trial Comparing Mail versus Telephone

Mick Couper, Andy Peytchev, Victor Strecher, Kendra Rothert, Julia Anderson

J Med Internet Res 2007 (Jun 13); 9(2):e16

HTML PDF XML Abstract

Background: Attrition, or dropout, is a problem faced by many online health interventions, potentially threatening the inferential value of online randomized controlled trials. Objective: In the context of a randomized controlled trial of an online weight management intervention, where 85% of the baseline participants were lost to follow-up at the 12-month measurement, the objective was to examine the effect of nonresponse on key outcomes and explore ways to reduce attrition in follow-up...

Internet-Based Interactive Health Intervention for the Promotion of Sensible Drinking: Patterns of Use and Potential Impact on Members of the General Public

Stuart Linke, Elizabeth Murray, Ceri Butler, Paul Wallace

J Med Internet Res 2007 (May 08); 9(2):e10

HTML PDF XML Abstract

Background: Heavy drinking is responsible for major health and social problems. Brief interventions have been shown to be effective, but there have been difficulties in reaching those who might benefit from them. Pilot studies have indicated that a Web-based intervention is likely to be acceptable to heavy drinkers and may produce some health benefits. However, there are few data on how many people might use such a program, the patterns of use, and potential benefits. Objectives: The aim...

A Survey of Quality Assurance Practices in Biomedical Open Source Software Projects

Günes Koru, Khaled El Emam, Angelica Neisa, Medha Umarji

J Med Internet Res 2007 (May 07); 9(2):e8

HTML PDF XML Abstract

Background: Open source (OS) software is continuously gaining recognition and use in the biomedical domain, for example, in health informatics and bioinformatics. Objectives: Given the mission critical nature of applications in this domain and their potential impact on patient safety, it is important to understand to what degree and how effectively biomedical OS developers perform standard quality assurance (QA) activities such as peer reviews and testing. This would allow the users of...

How Cancer Survivors Provide Support on Cancer-Related Internet Mailing Lists

Andrea Meier, Elizabeth Lyons, Gilles Frydman, Michael Forlenza, Barbara Rimer

J Med Internet Res 2007 (May 14); 9(2):e12

HTML PDF XML Abstract

Background: Internet mailing lists are an important and increasingly common way for cancer survivors to find information and support. Most studies of these mailing lists have investigated lists dedicated to one type of cancer, most often breast cancer. Little is known about whether the lessons learned from experiences with breast cancer lists apply to other cancers. Objectives: The aim of the study was to compare the structural characteristics of 10 Internet cancer-related mailing lists and...

User-Centered Research on Breast Cancer Patient Needs and Preferences of an Internet-Based Clinical Trial Matching System

Nancy Atkinson, Holly Massett, Christy Mylks, Bethany Hanna, Mary Deering, Bradford Hesse

J Med Internet Res 2007 (May 15); 9(2):e13

HTML PDF XML Abstract

Background: Internet-based clinical trial matching systems have the potential to streamline the search process for women with breast cancer seeking alternative treatments. A prototype system was developed to leverage the capabilities of a personal health record system for the purpose of identifying clinical trials. Objective: This study examines how breast cancer patients perceive and interact with a preliminary version of an Internet-based clinical trial matching system, while taking into...

Pilot Randomized Trial of the Effect of Wireless Telemonitoring on Compliance and Treatment Efficacy in Obstructive Sleep Apnea

Carl Stepnowsky (Jr.), Joe Palau, Matthew Marler, Allen Gifford

J Med Internet Res 2007 (May 17); 9(2):e14

HTML PDF XML Abstract

Background: Obstructive sleep apnea (OSA) is a prevalent and serious medical condition characterized by repeated complete or partial obstructions of the upper airway during sleep and is prevalent in 2% to 4% of working middle-aged adults. Nasal continuous positive airway pressure (CPAP) is the gold-standard treatment for OSA. Because compliance rates with CPAP therapy are disappointingly low, effective interventions are needed to improve CPAP compliance among patients diagnosed with OSA....
