BACKGROUND Replacement of caloric beverages with noncaloric beverages may be a simple strategy for promoting modest weight reduction; however, the effectiveness of this strategy is not known. OBJECTIVE We compared the replacement of caloric beverages with water or diet beverages (DBs) as a method of weight loss over 6 mo in adults and attention controls(More)
OBJECTIVE To examine the impact of a weight loss intervention that focused on daily self-weighing for self-monitoring as compared to a delayed control group among 91 overweight adults. DESIGN AND METHODS The 6-month intervention included a cellular-connected "smart" scale for daily weighing, web-based weight loss graph, and weekly e-mails with tailored(More)
BACKGROUND To our knowledge, no studies have evaluated whether weight loss can be promoted in overweight adults through the use of an intervention that is largely based on daily SMS (Short Message Service: text) and MMS (Multimedia Message Service: small picture) messages transmitted via mobile phones. OBJECTIVE This paper describes the development and(More)
Computers and the Internet have the potential to be used to deliver psychological treatments. This article provides a selective review of applications involving little or no therapist contact, applications involving asynchronous and synchronous communication with providers, and applications that have been used as adjuncts to standard psychotherapy. Data on(More)
Several recent studies suggest that daily weighing is important for long-term weight control, but concerns have been raised about possible adverse psychological effects. The "STOP Regain" clinical trial provides a unique opportunity to examine this issue both cross-sectionally and prospectively. Successful weight losers (N = 314) were randomly assigned to a(More)
Few studies have examined predictors of weight regain after significant weight losses. This prospective study examined behavioral and psychological predictors of weight regain in 261 successful weight losers who completed an 18-month trial of weight regain prevention that compared a control condition with self-regulation interventions delivered face-to-face(More)
BACKGROUND Web-based behavioral programs efficiently disseminate health information to a broad population, and online tailoring may increase their effectiveness. While the number of Internet-based behavioral interventions has grown in the last several years, additional information is needed to understand the characteristics of subjects who enroll in these(More)
Depression has been linked to poor health outcome in a number of studies; however, the mechanism underlying this relationship has received little attention. This paper explores the possibility that adherence mediates the relationship between depression and outcome. Principal findings regarding the relationship between depression, adherence, and outcome are(More)
BACKGROUND Internet interventions have a large potential for public health impact, and their efficacy has been established over the past 10-15 years. Cost effectiveness of Internet interventions is one of the most frequently cited reasons for developing such treatments. PURPOSE This paper provides a review of economic evaluations of Internet interventions(More)
BACKGROUND Intensive interventions targeting diet and physical activity are effective for weight reduction but are costly. Tailored, computer-generated, step-count feedback may provide an intensive and affordable way to increase the physical activity of people at high risk for cardiovascular disease. OBJECTIVE The objective was to test the feasibility of(More)
