Randomized Controlled TrialMotivating social distancing during the COVID-19 pandemic: An online experiment.
Maintaining social distance during the COVID-19 pandemic can save lives. We therefore set out to test communication strategies to promote social distancing. ⋯ Messages that invoke thoughts of infecting vulnerable people or large numbers of people can motivate social distancing and, hence, help to limit the spread of COVID-19. Stated public evaluations (obtained via focus groups or surveys) may underestimate the actual effectiveness of such emotional messages.

Randomized Controlled TrialPromoting physical activity in high-poverty neighborhood parks: A cluster randomized controlled trial.
Although physical activity can help mitigate or prevent multiple chronic diseases, most people in the U. S., especially high-poverty minority groups, engage in insufficient levels of physical activity. To test ways to promote more physical activity in high-poverty area public parks we conducted a randomized controlled intervention trial. ⋯ The process evaluation uncovered several barriers to program implementation, including inconsistent scheduling of classes, partly due to safety concerns among instructors. Multiple social factors interfere with leisure time physical activity among low-income populations, suggesting modest interventions may be insufficient to overcome these issues. Although new park programs can attract users, new programs alone may be insufficient to increase overall park use in low-income neighborhoods at times when the programs are not taking place.

Randomized Controlled TrialEffectiveness of public deliberation methods for gathering input on issues in healthcare: Results from a randomized trial.
Public deliberation elicits informed perspectives on complex issues that are values-laden and lack technical solutions. This Deliberative Methods Demonstration examined the effectiveness of public deliberation for obtaining informed public input regarding the role of medical evidence in U.S. healthcare. We conducted a 5-arm randomized controlled trial, assigning participants to one of four deliberative methods or to a reading materials only (RMO) control group. The four deliberative methods reflected important differences in implementation, including length of the deliberative process and mode of interaction. The project convened 76 groups between August and November 2012 in four U.S. ⋯ Chicago, IL; Sacramento, CA; Silver Spring, MD; and Durham, NC, capturing a sociodemographically diverse sample with specific attention to ensuring inclusion of Hispanic, African-American, and elderly participants. Of 1774 people recruited, 75% participated: 961 took part in a deliberative method and 377 participants comprised the RMO control group. To assess effectiveness of the deliberative methods overall and of individual methods, we evaluated whether mean pre-post changes on a knowledge and attitude survey were statistically different from the RMO control using ANCOVA. In addition, we calculated mean scores capturing participant views of the impact and value of deliberation. Participating in deliberation increased participants' knowledge of evidence and comparative effectiveness research and shifted participants' attitudes regarding the role of evidence in decision-making. When comparing each deliberative method to the RMO control group, all four deliberative methods resulted in statistically significant change on at least one knowledge or attitude measure. These findings were underscored by self-reports that the experience affected participants' opinions. Public deliberation offers unique potential for those seeking informed input on complex, values-laden topics affecting broad public constituencies.

Randomized Controlled TrialEffectiveness of a parenting program in Bangladesh to address early childhood health, growth and development.
A stratified cluster design was used to evaluate a 10-month parenting program delivered to mothers of children in rural Bangladesh. Intervention mothers through a combination of group meetings and home visits received messages along with an illustrative card concerning hygiene, responsive feeding, play, communication, gentle discipline, and nutritious foods. Control mothers received the standard government care. ⋯ Age effects were found only for dietary diversity in that younger children in the program benefited more than older ones. However, all children became more stunted. Findings are discussed in terms of theories of behaviour change and parenting, critical ages for parenting programs, and implications for program delivery.

Randomized Controlled TrialThe seven Cs of the high acceptability of home-based VCT: results from a mixed methods approach in Zambia.
HIV testing and counselling is a critical gateway to prevention and treatment. Yet, coverage remains insufficient, few couples are tested together and gender differences in access exist. We used an embedded mixed methods approach to investigate possible explanations for the high acceptance of home-based voluntary HIV counselling and testing (HB-VCT) in a pair-matched cluster-randomized trial in Zambia. ⋯ The high level of couple counselling within HB-VCT may contribute to closing the gender gap in HIV testing, and has benefits for both genders and potentially for prevention of HIV transmission. The study demonstrates the feasibility of achieving high test coverage with an opt-in consent approach. The embedded qualitative component confirmed the high satisfaction with HB-VCT reported in the quantitative survey and was crucial to fully understand the intervention and its consequences.
