The purpose of this pilot study was to conduct an impact evaluation of a 10-week Web-based physical activity intervention.
Quasi-experimental, three-group pretest, posttest design.
Large Midwestern university.
Participants (N = 233) included college students registered for three courses. The study employed a convenience sample consisting of a Web-based group (n = 108), a physical activity group (n = 64), and a general health group (n = 61).
The Web-based group received a Social Cognitive Theory behavioral skill-building intervention and exercised 3 days per week in their leisure time. The physical activity group received exercise instruction and was required to attend three physical activity labs per week. The comparison group received health instruction.
Outcome variables included moderate and vigorous physical activity, self-regulation, social support, self-efficacy, and outcome expectations and expectancies.
Differences between groups were assessed at pretest and posttest using multiple analyses of variance.
Vigorous physical activity, self-regulation, and outcome expectancy value changed significantly in the Web-based and physical activity course groups (p < .01).
Even with consideration of limitations such as small sample size and lack of randomization, the Web-based and traditional physical activity lecture and activity lab interventions were superior in eliciting changes in vigorous physical activity, self-regulation, and outcome expectancy value than a traditional health course.

    ABSTRACT: This article provides a comprehensive review of Internet- and Website-based physical activity interventions targeting adult populations. Search procedures identified 72 unique Internet-based physical activity interventions published in peer-reviewed journals. Participants of the studies were predominately White, middle-aged (mean age = 43.3 years), and female (65.9%). Intervention durations ranged from 2 weeks to 13 months (median = 12 weeks). Forty-six of the studies were randomized controlled trials, 21 were randomized trials without a control condition, 2 were non-randomized controlled trials, and 3 used a single-group design. The majority of studies (n = 68) assessed outcomes immediately following the end of the intervention period, and 16 studies provided delayed postintervention assessments. Forty-four of the 72 studies (61.1%) reported significant increases in physical activity. Future directions for Internet-based physical activity interventions include increasing representation of minority and male populations in Internet-based efforts, conducting delayed postintervention follow-up assessments, and incorporating emerging technologies (ie, cellular and Smartphones) into Internet-based physical activity efforts.

    ABSTRACT: OBJECTIVE: To identify types of technological support and information content utilized to promote therapeutic regimen management for patients with chronic obstructive pulmonary disease (COPD). METHODS: In this study, which had a quantitative, exploratory, descriptive, and transversal approach, the authors used a questionnaire organized on the basis of a literature review and two models: One of acceptance of the technology and a theoretical one of the determinants for patients' perceived ease of its use. RESULTS: The patients with COPD reported need for more information related to their daily activities and breathing exercises. Patients who had higher literacy and higher technological literacy reported that web-based technologies were more useful. Those who had lower literacy and lower technological literacy reported higher usefulness, intention and ease of use of mobile phone books, and videos in the access to information.CONCLUSION: Information resources may use any technological support, provided information is available according to the literacy and technological literacy of the patients and tailored to their needs.

    ABSTRACT: Many internet-delivered physical activity behaviour change programs have been developed and evaluated. However, further evidence is required to ascertain the overall effectiveness of such interventions. The objective of the present review was to evaluate the effectiveness of internet-delivered interventions to increase physical activity, whilst also examining the effect of intervention moderators. A systematic search strategy identified relevant studies published in the English-language from Pubmed, Proquest, Scopus, PsychINFO, CINHAL, and Sport Discuss (January 1990 - June 2011). Eligible studies were required to include an internet-delivered intervention, target an adult population, measure and target physical activity as an outcome variable, and include a comparison group that did not receive internet-delivered materials. Studies were coded independently by two investigators. Overall effect sizes were combined based on the fixed effect model. Homogeneity and subsequent exploratory moderator analysis was undertaken. A total of 34 articles were identified for inclusion. The overall mean effect of internet-delivered interventions on physical activity was d = 0.14 (p = 0.00). Fixed-effect analysis revealed significant heterogeneity across studies (Q = 73.75; p = 0.00). Moderating variables such as larger sample size, screening for baseline physical activity levels and the inclusion of educational components significantly increased intervention effectiveness. Results of the meta-analysis support the delivery of internet-delivered interventions in producing positive changes in physical activity, however effect sizes were small. The ability of internet-delivered interventions to produce meaningful change in long-term physical activity remains unclear.
