Comparison of trial participants and open access users of a web-based physical activity intervention regarding adherence, attrition, and repeated participation.
ABSTRACT Web-based interventions are popular for promoting healthy lifestyles such as physical activity. However, little is known about user characteristics, adherence, attrition, and predictors of repeated participation on open access physical activity websites.
The focus of this study was Active-online, a Web-based individually tailored physical activity intervention. The aims were (1) to assess and compare user characteristics and adherence to the website (a) in the open access context over time from 2003 to 2009, and (b) between trial participants and open access users; and (2) to analyze attrition and predictors of repeated use among participants in a randomized controlled trial compared with registered open access users.
Data routinely recorded in the Active-online user database were used. Adherence was defined as: the number of pages viewed, the proportion of visits during which a tailored module was begun, the proportion of visits during which tailored feedback was received, and the time spent in the tailored modules. Adherence was analyzed according to six one-year periods (2003-2009) and according to the context (trial or open access) based on first visits and longest visits. Attrition and predictors of repeated participation were compared between trial participants and open access users.
The number of recorded visits per year on Active-online decreased from 42,626 in 2003-2004 to 8343 in 2008-2009 (each of six one-year time periods ran from April 23 to April 22 of the following year). The mean age of users was between 38.4 and 43.1 years in all time periods and both contexts. The proportion of women increased from 49.5% in 2003-2004 to 61.3% in 2008-2009 (P< .001). There were differences but no consistent time trends in adherence to Active-online. The mean age of trial participants was 43.1 years, and 74.9% were women. Comparing contexts, adherence was highest for registered open access users. For open access users, adherence was similar during the first and the longest visits; for trial participants, adherence was lower during the first visits and higher during the longest visits. Of registered open access users and trial participants, 25.8% and 67.3% respectively visited Active-online repeatedly (P< .001). Predictors of repeated use were male sex (odds ratio [OR] = 1.2, 95% confidence interval [CI] = 1.04-1.38) and increasing age category in registered open access users, and age 46-60 versus < 30 years (OR = 3.04, 95% CI = 1.25-7.38) and Swiss nationality (OR(nonSwiss)= 0.64, 95% CI = 0.41-1.00) in trial participants. Despite reminder emails, attrition was much higher in registered open access users compared with trial participants, with a median lifetime website usage of 0 days in open access users and 290 days in trial participants.
Adherence, patterns of use, attrition, and repeated participation differed between trial participants and open access users. Reminder emails to encourage repeated participation were effective for trial participants but not for registered open access users. These issues are important when interpreting results of randomized controlled effectiveness trials.

ABSTRACT: As PPI research embraces the use of the Internet, it is incumbent on the research community to keep up with the ever-evolving best practices in online intervention research. This paper provides an overview of current practices in online positive psychological intervention (OPPI) research and suggests improvements to those practices. Drawing from the broader online intervention literature, the paper outlines important considerations in the design of OPPIs (including user engagement, dosage, and free choice) as well as in their empirical evaluation (including sample selection, statistical approaches, and comparison groups).The Journal of Positive Psychology 07/2014; 9(6):502-508.

ABSTRACT: Introduction. In 2010 the Italian Ministry of Health set out recommendations for the use of social technology and Web 2.0, inviting organisations within the Italian national health service (Servizio Sanitario Nazionale, SSN) to equip themselves with instruments. Objectives. 1. to ascertain how many local health authorities (Aziende Sanitarie Locali, ASL) and public hospitals have a presence on the most widely used social media websites in Italy: Facebook, Twitter and YouTube; 2. to find out how well the Facebook, Twitter and YouTube pages of ASLs and public hospitals are known among the general population; 3. to find out how ASLs and public hospitals engage with the general public on social media sites. Materials and methods. The websites of all ASLs and public hospitals across the country were visited to look for the icons of the social media sites under examination. The data considered were publicly available upon access. Results. A total of 245 websites were analysed. 7.34% ASLs and hospitals had social media accounts. 8 organisations had an account on all three of the social media sites considered in the study. Conclusions. The results show a low presence of ASLs and hospitals on social media. Other studies are needed in this field.Annali dell'Istituto superiore di sanita 01/2014; 50(2):163-70.

ABSTRACT: Physical inactivity is an important risk factor in several highly prevalent diseases, being associated with worse quality of life and higher mortality. Despite the implementation of a several global, national and local policy instruments and strategies to promote physical activity (PA), including Internet platforms and advertising campaign, approximately two thirds of the European adult population reports low adherence to an active lifestyle, impairing health benefits that exercise can provide. Increasing efforts to provide adequate information have been made, and the use of new technologies tools has increased, but little investigation focus on the effect of information exposure on knowledge retention, regarding effects of physical inactivity in health. The objective of the present study is to evaluate differences among people in the use of new information technologies as information source on PA, regarding their perceptions of benefits of an active lifestyle and characteristics of adequate physical activity to health improvement. The study included a randomly recruited sample of 879 subjects (53% males; 47% females), age 42.3±19.4 years old. A survey was designed to (1) identify main information sources; (2) relate perceived knowledge and PA information sources; (3) relate knowledge retention on adequate PA for health benefits and PA information sources; (4) relate perceived necessity of more information regarding PA and information sources and (5) relate PA levels and information sources. Results show that two information sources (teacher and sport professionals) positively influence perception of proper PA information. Results also found teachers, Internet and sport professionals as PA information sources that most influence their users, regarding Knowledge retention. We also found that rely on friends/family; teachers, Internet and sport professionals as PA information sources positively influence the adoption of an active lifestyle.
