Every day, acts of violence injure more than 6000 people in the United States. Despite decades of social science arguing that joblessness among disadvantaged youth is a key cause of violent offending, programs to remedy youth unemployment do not consistently reduce delinquency. This study tests whether summer jobs, which shift focus from remediation to prevention, can reduce crime. In a randomized controlled trial among 1634 disadvantaged high school youth in Chicago, assignment to a summer jobs program decreases violence by 43% over 16 months (3.95 fewer violent-crime arrests per 100 youth). The decline occurs largely after the 8-week intervention ends. The results suggest the promise of using low-cost, well-targeted programs to generate meaningful behavioral change, even with a problem as complex as youth violence.

Objectives. To test whether fruit drink countermarketing messages alone or combined with water promotion messages reduce Latinx parents’ purchases of fruit drinks for children aged 0 to 5 years. Methods. We performed a 3-arm randomized controlled online trial enrolling 1628 Latinx parents in the United States during October and November 2019. We assessed the effect of culturally tailored fruit drink countermarketing messages (fruit drink‒only group), countermarketing and water promotion messages combined (combination group), or car-seat safety messages (control) delivered via Facebook groups for 6 weeks on parental beverage choices from a simulated online store. Results. The proportion of parents choosing fruit drinks decreased by 13.7 percentage points in the fruit drink‒only group (95% confidence interval [CI] = −20.0, −7.4; P < .001) and by 19.2 percentage points in the combination group (95% CI = −25.0, −13.4; P < .001) relative to control. Water selection increased in both groups. Conclusions. Fruit drink countermarketing messages, alone or combined with water promotion messages, significantly decreased parental selection of fruit drinks and increased water selection for their children. Public Health Implications. Countermarketing social media messages may be an effective and low-cost intervention for reducing parents’ fruit drink purchases for their children. (Am J Public Health.

Background. As stroke survival improves, there is an increasing need for effective, low-cost programs to reduce deconditioning and improve mobility. Objective. To conduct a phase II trial examining whether the community-based Italian Adaptive Physical Activity exercise program for stroke survivors (APA-Stroke) is safe, effective, and feasible in the United States. Methods. In this single-blind, randomized controlled trial, 76 stroke survivors with mild to moderate hemiparesis >6 months were randomized to either APA-Stroke (N = 43) or Sittercise (N = 33). APA-Stroke is a progressive group exercise regimen tailored to hemiparesis that includes walking, strength, and balance training. Sittercise, a seated, nonprogressive aerobic upper body general exercise program, served as the control. Both interventions were 1 hour, 3 times weekly, in 5 community locations, supervised by exercise instructors. Results. A total of 76 participants aged 63.9 ± 1.2 years, mean months poststroke 61.8 ± 9.3, were included. There were no serious adverse events; completion rates were 58% for APA-Stroke, 70% for Sittercise. APA-Stroke participants improved significantly in walking speed. Sample size was inadequate to demonstrate significant between-group differences. Financial and logistical feasibility of the program has been demonstrated. Ongoing APA classes have been offered to >200 participants in county Senior Centers since study completion. Conclusion. APA-Stroke shows great promise as a low-cost, feasible intervention. It significantly increased walking speed. Safety and feasibility in the US context are demonstrated. A pivotal clinical trial is required to determine whether APA-Stroke should be considered standard of care.

Background/Context Billions of dollars are spent annually on professional development (PD) for educators, yet few randomized controlled trials (RCT) have demonstrated the ultimate impact PD has on student learning. Further, while policymakers and others speak to the role schools should play in developing students’ civic awareness, RCTs of PD designed to foster civic learning are rare. This randomized controlled trial contributes to the knowledge base on the effectiveness of PD designed to integrate civic learning, ethical reflection, and historical thinking skills into high school humanities courses. Focus of Study The study examined the impact of a PD intervention in two areas: (a) teacher self-efficacy, burnout, and professional engagement and satisfaction; and (b) the academic, civic, social, and ethical competencies of 9th and 10th grade students in the teachers’ classes. Population/Participants/Subjects The study involved 113 teachers and 1,371 9th and 10th grade students in 60 high schools from eight metropolitan regions in the United States. Intervention/Program/Practice The intervention, Facing History and Ourselves, provides PD through a five-day seminar, curricular materials, and follow-up coaching and workshops to help teachers develop their capacities to implement an interdisciplinary historical case study unit using student-centered pedagogy. Research Design The study used a school-level, randomized, experimental design to investigate impacts of the intervention for teachers and their 9th and 10th grade students. Findings/Results Intervention teachers showed significantly greater self-efficacy in all eight assessed domains, more positive perceptions of professional support, satisfaction and growth, and greater personal accomplishment. Intervention students demonstrated stronger skills for analyzing evidence, agency, and cause and effect on a historical understanding performance measure; greater self-reported civic efficacy and tolerance for others with different views; and more positive perceptions of the classroom climate and the opportunities afforded for engaging with civic matters. Fidelity analysis found these causal effects despite the fact that roughly half of the intervention teachers did not fully implement the program. Conclusions/Recommendations Educators need evidence-based approaches for teaching complex social, civic, and political issues enabling students of diverse mindsets and backgrounds to engage constructively with one another while obtaining necessary skills and knowledge. These findings provide empirical support for a professional development approach that engages teachers in fostering academic and civic competencies critical to both participation in a democracy and success in college and career.

An understanding of fractions eludes many U.S. students, and research-based knowledge about fractions, such as the utility of linear representation, has not broadly influenced instruction. This randomized trial of lesson study supported by mathematical resources assigned 39 educator teams across the United States to locally managed lesson study supported by a fractions lesson study resource kit or to 1 of 2 control conditions. Educators (87% of whom were elementary teachers) self-managed learning over a 3-month period. HLM analyses indicated significantly greater improvement of educators' and students' fractions knowledge for teams randomly assigned to lesson study with resource kits. Results suggest that integrating researchbased resources into lesson study offers a new approach to the problem of “scale-up” by combining the strengths of teacher leadership and research-based knowledge.

Vaccination rates have stagnated in the United States and the United Kingdom leading to the continuing spread of COVID-19. Fear and concern over vaccine side-effects is one of the main drivers of hesitancy. Drawing from behavioral science and health communication theory, we conducted a randomized controlled trial among 8998 adults to determine whether the way COVID-19 vaccine side-effects are framed and presented to individuals can influence their willingness to take a vaccine. We presented participants information on a hypothetical future COVID-19 vaccine -- including information on its side-effect rate -- and then examined the effect of three side-effect framing strategies on individuals stated willingness to take this vaccine: adding a qualitative risk label next to the numerical risk, adding comparison risks, and for those presented with comparisons, framing the comparison in relative rather than absolute terms. Based on a pre-registered and published analysis plan, we found that adding a simple descriptive risk label (very low risk) next to the numerical side-effect increased participants' willingness to take the COVID-19 vaccine by 3.0 percentage points (p = 0.003). Providing a comparison to motor vehicle mortality increased COVID-19 vaccine willingness by 2.4 percentage points (p = 0.051). These effects were independent and additive: participants that received both a qualitative risk label and comparison to motor-vehicle mortality were 6.1 percentage points (p < 0.001) more likely to report willingness to take a vaccine compared to those who did not receive a label or comparison. Taken together, our results reveal that despite increasingly strong vaccination hesitancy and exposure to large amounts of vaccine misinformation, low-cost side-effect framing strategies can meaningfully affect vaccination intentions at a population level.

Abstract Background Although the evidence suggests that general fatigue is a strong indicator of rapid aging, frailty, and disability, general fatigue is undertreated in gerontological care. Objective The aim of this study is to investigate whether an individualized exercise program with and without behavioral change enhancement (BCE) strategies for older people who are frail and have general fatigue will reduce their fatigue and symptoms of frailty. Design A 3-arm, single-blind, cluster randomized controlled trial registered with ClinicalTrials.gov (NCT03394495) will be conducted. Setting The study will be conducted in a community setting. Participants Two hundred eighty-five community-dwelling older people with general fatigue will be recruited from 12 district community health centers. Intervention People from each center will be randomized to one of three groups. The combined group will receive a 16-week combined intervention consisting of individualized exercise training and the BCE program, plus two booster sessions at 2 and 6 months after the program. The exercise group will receive exercise training and health talks only. The control group will receive health talks only. Measurements Outcome measures will be collected at baseline, at the midpoint (week 8) of the program, and then at 1 week, 6 months, and 12 months after the end of the program. The primary outcome---level of fatigue---will be measured using the Multidimensional Fatigue Inventory. Secondary outcomes will include the participants’ frailty status, strength, mobility, exercise self-efficacy, and habitual physical activity. Limitations A self-reported level of fatigue will be used. Conclusions The effect of exercise and BCE strategies on general fatigue among older people who are frail is not known. This study will be a pioneering interventional study on how general fatigue among older people who are frail can be managed and how fatigue-related frailty can be prevented or minimized.
