Objective: To quantify students' risk tolerance for in-person classes and willingness-to-pay for online-only instruction during the COVID-19 pandemic. Participants: 46 Columbia University public health graduate students. Methods: We developed a survey tool with a "standard gamble" exercise administered online by an interactive chat bot with full anonymity by students. Students were asked to trade between the risk of infection with COVID-19 and: (1) attending classes in-person, and (2) attending community parties. We also assessed willingness-to-pay for online-only tuition. Results: Students accepted a 23% (standard error [SE]: 4%) risk of infection to attend classes in-person and 15% of them expressed willingness to attend community parties even if the COVID-19 prevalence were high. Students were willing-to-pay only 48% (SE: 3%) of the regular, in-person tuition fees for online instruction. Conclusions: Public health students with a strong knowledge of COVID-19 transmission were willing to accept a significant risk of infection for in-person instruction. Trial registration: NA.

This study assesses whether anti-immigrant prejudice at the community level is prospectively associated with mortality. We used 10 waves of data from the General Social Survey (GSS) that were linked to mortality data via the National Death Index (NDI) for the period between 1993 and 2014 (n = 13,242). The 2014 GSS-NDI dataset is a nationally representative sample reporting social characteristics and attitudes in the United States that was prospectively linked to mortality data. Community-level prejudice was measured with 5 questions regarding anti-immigrant sentiments across 123 communities, defined using primary sampling units. Cox proportional hazards models tested the association between anti-immigrant prejudice and mortality hazard, controlling for covariates at the individual and community levels. Findings showed that among "other race" respondents, those born in the US had higher risk of mortality in communities with greater anti-immigrant prejudice, whereas foreign-born "other race" respondents had lower risk of mortality in communities with greater anti-immigrant prejudice. Sensitivity analyses indicated that the "other race" category was comprised largely of Asians and Hispanics, and that these results were similar for both groups. In contrast, anti-immigrant prejudice was not associated with mortality for foreign-born immigrants who self-report as white or black. We provide various hypotheses for why US-born immigrant groups seem to suffer higher mortality risk, while foreign-born immigrant groups do not, when they live in communities with high levels of prejudice.

There are 25 million displaced children worldwide, and those receiving schooling are often educated in overcrowded classrooms. Montessori is a child-centred educational method that provides an alternative model to traditional educational approaches. In this model, students are able to direct their own learning and develop at their own pace, working with materials rather than in supervised groups or with direct teacher instruction. Because most children are working alone, teachers have more time to work one-on-one with children even when student-teacher ratios are quite large. This gives teachers increased opportunity to tailor their teaching to the specific needs and strengths of each student. We conducted an evaluation of Montessori classroom conversion for displaced students on the Thai-Myanmar border. We administered the Ages and Stages Questionnaire (ASQ) to 66 children before and after classroom conversion and across treatment and control classroom conditions. We then conducted difference in difference testing. All domains showed meaningful improvements in ASQ scores, with the Montessori students gaining 18 points relative to the traditional students (p = 0.33). However, only the personal-social domain of the ASQ was statistically significant (8.8 point gain for the Montessori students relative to the control, p < 0.05) in our underpowered sample.

Policy PointsThe Paycheck Plus randomized controlled trial tested a fourfold increase in the Earned Income Tax Credit (EITC) for single adults without dependent children over 3 years in New York and Atlanta.In New York, the intervention improved economic, mental, and physical health outcomes. In Atlanta, it had no economic benefit or impact on physical health and may have worsened mental health.In Atlanta, tax filing and bonus receipt were lower than in the New York arm of the trial, which may explain the lack of economic benefits. Lower mental health scores in the treatment group were driven by disadvantaged men, and the study sample was in good mental health. Context: The Paycheck Plus experiment examined the effects of an enhanced Earned Income Tax Credit (EITC) for single adults on economic and health outcomes in Atlanta, GA and New York City (NYC). The NYC study was completed two years prior to the Atlanta study and found mental and physical benefits for the subgroups that responded best to the economic incentives provided. In this article, we present the findings from the Atlanta study, in which the uptake of the treatment (tax filings and EITC bonus) were lower and economic and health benefits were not observed. Methods: Paycheck Plus Atlanta was an unblinded randomized controlled trial that assigned n = 3,971 participants to either the standard federal EITC (control group) or an EITC supplement of up to $2,000 (treatment group) for three tax years (2017–2019). Administrative data on employment and earnings were obtained from the Georgia Department of Labor and survey data were used to examine validated measures of health and well‐being. Findings: In Atlanta, the treatment group had significantly higher earnings in the first project year but did not have significantly higher cumulative earnings than the control group overall (mean difference = $1,812, 95% CI = −150, 3,774, p = 0.07). The treatment group also had significantly lower scores on two measures of mental health after the intervention was complete: the Patient Health Questionnaire 8 (mean difference = 0.19, 95% CI = 0.06, 0.32, p = 0.005) and the Kessler 6 (mean difference = 0.15, 95% CI = 0.03, 0.27, p = 0.012). Secondary analyses suggested these results were driven by disadvantaged men, but the study sample was in good mental health. Conclusions: The EITC experiment in Atlanta was not associated with gains in earnings or improvements in physical or mental health. [ABSTRACT FROM AUTHOR]

BackgroundProposals to expand Medicare coverage tend to be expensive, but the value of services purchased is not known. This study evaluates the efficiency of the average private supplemental insurance plan for Medicare recipients.MethodsData from the National Health Interview Survey, the National Death Index, and the Medical Expenditure Panel Survey were analyzed to estimate the costs, changes in life expectancy, and health-related quality of life gains associated with providing private supplemental insurance coverage for Medicare beneficiaries. Model inputs included socio-demographic, health, and health behavior characteristics. Parameter estimates from regression models were used to predict quality-adjusted life years (QALYs) and costs associated with private supplemental insurance relative to Medicare only. Markov decision analysis modeling was then employed to calculate incremental cost-effectiveness ratios.ResultsMedicare supplemental insurance is associated with increased health care utilization, but the additional costs associated with this utilization are offset by gains in quality-adjusted life expectancy. The incremental cost-effectiveness of private supplemental insurance is approximately $24,000 per QALY gained relative to Medicare alone.ConclusionSupplemental insurance for Medicare beneficiaries is a good value, with an incremental cost-effectiveness ratio comparable to medical interventions commonly deemed worthwhile.

Privacy and confidentiality are often of great concern to respondents answering sensitive questions posed by interviewers. Using the 1993-2010 General Social Survey, we examined trends in the provision of social security numbers (SSNs) and correlates of those responses. Results indicate that the rate of SSN provision has declined over the past three decades, that is, from about 60% in 1993-1994 to 20% after 2004. Although younger, unmarried, and less-educated respondents are more likely to provide SSNs, an indicator of trust toward others is not a significant predictor of SSN provision. Further, those who refuse to report their income and who receive an incentive are less likely to provide their SSN. Our findings have implications for studies involving sensitive questions as well as privacy and confidentiality issues.
