ObjectiveDo computer prompt software programs at the workplace reduce sitting time and/or increase physical activity at work?BackgroundMany products are promoted and being used in the workplace; however, their effectiveness and use are unknown or the evidence base that they work to change behavior is lacking.MethodWe searched for relevant papers published between 2005 and 2020. The inclusion criteria were computer prompt software programs installed as behavioral change interventions; interventions implemented during work hours and delivered through a work personal computer or laptop; and measures of sedentary behavior and/or physical activity. To minimize risk of bias, three recommended best-evidence synthesis criteria were used: random assignment, sample size, and external validity. Based on these criteria, articles were selected and evaluated.ResultsSix publications met the quality threshold for review. Seven articles did not meet the quality threshold. Four of the six included publications found that computer prompt software programs decreased sedentary behavior and/or increased physical activity. Two publications reported inconsistent results.ConclusionsThe promising results from this systematic review indicate that there is potential for computer prompt software programs to improve the health of desk-based workers. For conclusive findings, more high-quality, scientific studies are needed.ApplicationThe best-evidence publications in this review can serve as a guide in selecting and implementing computer prompt software programs at the workplace to decrease sedentary behavior and increase physical activity.

Collective violence is a major cause of death, illness, and suffering. The theory of moral disengagement offers a framework for understanding and preventing violence between nations, and the Internet provides a vehicle for reaching a diverse population with a war-prevention program. The objectives of the PeaceTest project were to develop, implement, and evaluate a theory-based interactive website to be used as a war-prevention intervention for a general audience. The open-access site www.PeaceTest.org is an intervention to increase visitors' resistance to the cognitive processes of moral disengagement through risk assessment and tailored remediation. Evaluation of the program used a single-group pre-test—posttest design involving self-reported attitudes toward the use of military force. From 13 May to 15 September 2004, the site recorded 7,521 self-selected visitors from around the world; 5,702 (76%) completed the pre-test, and 338 (6%) of these completed the post-test. The intervention effect was examined using paired t-tests. A majority of respondents (75%) recorded PeaceTest scores indicating they were at risk of moral disengagement. Women, medical/public health students, older visitors, and non-US visitors showed significantly greater resistance to moral disengagement than other demographic groups ( p < 0.01). Resistance increased significantly among those who took the post-test ( p < 0.01), especially among women. The number, predisposition, and characteristics of respondents were strongly affected by efforts to promote the site and by the site's launching at a time of intense public sentiment about the US-led war in Iraq. The authors conclude that the PeaceTest project demonstrated the potential to produce change in war-promoting attitudes in an unrestricted population, though findings must be interpreted in the light of study-design limitations. Controversy and publicity can briefly generate a large audience, but that audience may arrive with strong predispositions. Gaining widespread acceptance and use of a web-based public-health approach to war prevention remains a worthwhile challenge.

Purpose. Developing and disseminating innovative and effective approaches for smoking prevention among middle school children remains a public health priority. This pilot study evaluates the use of a Web-based tobacco prevention program, Headbutt, to change intentions of middle school children to smoke tobacco. Methods. Headbutt was implemented with the use of a single-group pretest-posttest study design in sixth grade classes of nine middle schools in Texas (student n = 2227). The program assesses cognitive determinants of smoking and provides intervention feedback tailored to the child's responses. Results. Headbutt significantly affected smoking intentions, prosmoking attitudes, self-efficacy expectations, and knowledge of negative consequences (all p ≤ .001) measured with scales adopted from the Texas Tobacco Initiative Survey. Change in prosmoking attitudes had the greatest predictive effect on smoking intentions (p < .001). These results were moderated by ethnicity and age of students. Conclusion. Findings need to be interpreted in the light of study design limitations. However, strong associations between the Headbutt program and intention change suggests that a more rigorous effectiveness trial is indicated.
