Survey Non-Response in COVID-19 Times: The Case of the Labour Force Survey.

During the COVID-19 pandemic, labour-force survey non-response rates have surged in many countries. We show that in the case of the Canadian Labour Force Survey (LFS), the bulk of this increase is due to the suspension of in-person interviews following the adoption of telework within Federal agencies, including Statistics Canada. Individuals with vulnerabilities to the COVID-19 economic shock have been harder to reach and have been gradually less and less represented in the LFS during the pandemic. We present evidence suggesting that the decline in employment and labour-force participation have been underestimated over the March-July 2020 period. We argue that these non-response issues are moderate when analyzing aggregate outcomes, but that researchers should exert caution when gauging the robustness of estimates for subgroups. We discuss practical implications for research based on the LFS, such as the consequences for panels and the choice of public-use versus master files of the LFS.

Pendant la pandémie de COVID-19, le taux de non-réponse aux enquêtes auprès de la population active a explosé dans beaucoup de pays. Nous montrons que dans le cas de l'Enquête canadienne sur la population active (EPA), le gros de cette hausse s'explique par la suspension des entrevues en personne qui a suivi l'adoption du télétravail dans les agences fédérales, y compris à Statistique Canada. Les personnes vulnérables au choc économique de la COVID-19 ont été plus difficiles à joindre et ont été de moins en moins représentées dans l'EPA au cours de la pandémie. Nous montrons, preuves à l'appui, que la diminution de l'emploi et de la participation à la main-d'œuvre est sous-estimée pour la période de mars à juillet 2020. Nous soutenons que la gravité de ces problèmes de non-réponses est modérée quand il s'agit d'analyser des résultats agrégés mais que la prudence s'impose dans l'évaluation de la robustesse des estimations pour les sous-groupes. Nous présentons les conséquences pratiques de cette situation pour les travaux qui reposent sur l'EPA, telles que les effets sur les panels et le choix entre données à grande diffusion et fichiers principaux de l'EPA.

Limitations introduced by a low participation rate of SARS-CoV-2 seroprevalence data.

BACKGROUND: There has been a large influx of COVID-19 seroprevalence studies, but comparability between the seroprevalence estimates has been an issue because of heterogeneities in testing platforms and study methodology. One potential source of heterogeneity is the response or participation rate. METHODS: We conducted a review of participation rates (PR) in SARS-CoV-2 seroprevalence studies collected by SeroTracker and examined their effect on the validity of study conclusions. PR was calculated as the count of participants for whom the investigators had collected a valid sample, divided by the number of people invited to participate in the study. A multivariable beta generalized linear model with logit link was fitted to determine if the PR of international household and community-based seroprevalence studies was associated with the factors of interest, from 1 December 2019 to 10 March 2021. RESULTS: We identified 90 papers based on screening and were able to calculate the PR for 35 out of 90 papers (39%), with a median PR of 70% and an interquartile range of 40.92; 61% of the studies did not report PR. CONCLUSIONS: Many SARS-CoV-2 seroprevalence studies do not report PR. It is unclear what the median PR rate would be had a larger portion not had limitations in reporting. Low participation rates indicate limited representativeness of results. Non-probabilistic sampling frames were associated with higher participation rates but may be less representative. Standardized definitions of participation rate and data reporting necessary for the PR calculations are essential for understanding the representativeness of seroprevalence estimates in the population of interest.

Possible Measures to Improve Both Participation and Response Quality in Japan's National Health and Nutrition Survey: Results from a Workshop by Local Government Personnel in Charge of the Survey.

Increasing participation rates are crucial to ensure the representativeness of national survey results of the population. This study aimed to identify measures that could be taken by local government personnel in charge of the National Health and Nutrition Survey (NHNS), Japan, to improve participation rates. The subjects were twenty-one health personnel who worked in 19 local governments and participated in the training course at the National Institute of Public Health. Qualitative data were collected through a workshop. They discussed the problems that seem to affect participation rates and identified possible solutions. The contents were coded and grouped to create categories, using the Jiro Kawakita (KJ) method. For data analysis, researchers combined and reviewed all codes and categories. The measures that could improve participation rates were divided into the following 12 categories: 1. standardization of survey methods, 2. investigator skills, 3. survey organization, 4. venue setting, 5. accessing target households, 6. time of survey, 7. responses during the investigation, 8. confirming meal contents reported in the nutritional intake status survey, 9. rewards/incentives, 10. possible rewards, 11. feedback on survey results, and 12. survey practices during the COVID-19 pandemic. These findings represent viable initiatives for local health personnel to increase participation rates for the NHNS.

The Evolution of Multi-Site Combined REU/RET Program: From In-Person to Virtual to Hybrid

In 2018, the Smart City Research Experience for Undergraduates (REU) and Research Experience for Teachers (RET) (SCR2) Mega-Site program was launched, aiming to improve the participation and graduation rates of post-secondary students of underrepresented and minority groups in the field of Engineering. Funded by the National Science Foundation (NSF), the SCR2 program has been successfully conducted for the last three years, engaging a consortium of 14 Historically Black Colleges and Universities (HBCUs) and 1 Hispanic Serving Institution (HSI). Morgan State University in Baltimore, Maryland, is the lead institution for this program. The SCR2 program is designed to engage underperforming REU students in research opportunities demonstrated to improve students' retention and graduation rates. In addition, teachers from local community colleges and high schools are recruited in this program as RET participants. The experience of RET participants in hands-on engineering research projects helps them encourage their students to pursue engineering as a career. The SCR2 program offers summer research experience (eight weeks for students and six weeks for teachers) focusing on smart and connected cities. In this paper, we present our learnings from the last three years of the SCR2 program, which will inform the progress of engineering education and training in the United States. While the 2019 SCR2 program was able to offer on-campus research experience and mentorship for the REU/RETs, the 2020 program had to go virtual to accommodate the extraneous circumstances posed by the COVID-19 pandemic. Despite this transition, the 2020 program engaged 32 undergraduates and 12 teachers, who successfully participated in 12 research projects across three host sites. Learning from the experience of the summer 2020 virtual program, the 2021 SCR2 program was redesigned as a hybrid program and was able to bring six host sites together, offering 18 projects in which 47 undergraduates and 23 teachers participated. One major success of the program was the positive impact of remote learning on both students and teachers. Despite the hybrid nature of the program, students excelled in their technical skills due to the effective collaboration using video conferencing tools. However, during the post-program survey, one primary concern was reported regarding the reduced participation of women students in the program. Simultaneously, the women participants reported less satisfaction and reduced confidence and knowledge gain than men. The transition of the SCR2 program from on-site to online and finally hybrid model exemplifies how innovation in engineering education can overcome the challenges posed by the health crisis. However, it is evident from the assessment results that more attention is needed concerning the experience of women in the program to improve their sense of belongingness in the field of engineering. © American Society for Engineering Education, 2022.

Pandemic-resilient target setting in colorectal cancer screening for vulnerable older population.

BACKGROUND: Colorectal cancer screening (CRCS) needs to be pandemic-resilient to avoid long-lasting shutdowns; however, realistic participation target remains unelucidated. This study aimed to identify the lowest acceptable participation rate in CRCS during a pandemic, focusing on vulnerable older populations who require urgent intervention. METHODS: This nationwide cross-sectional study included 80,946 inpatients aged 70-85 years who were first diagnosed with colorectal cancer (CRC) after 70 years of age, between April 1, 2014 and March 31, 2019, in Japan. To evaluate the association between area-level CRCS participation rate and individual early CRC detection, a multilevel logistic regression model was constructed. The mandatorily implemented screening rates were converted to the total screening rate equivalents (TSREs), which reflect the remaining contributions of voluntarily provided screenings. RESULTS: Early detections during stages 0-I were significantly observed when primary screening rate was ≥38% (TSRE) and combined follow-up rate was ≥85%. For early detection during Tis-T1, primary screening rate ≥ 38% (TSRE) and combined follow-up rate ≥ 90% were necessary. For follow-up rates ≥70% or ≥75%, there were cases where missed detection of Tis-T1 were observed. CONCLUSION: The results indicate that, even during pandemic, CRCS should achieve a primary screening rate of 38% and follow-up rate of 85% for vulnerable older populations. These values, lower than the current desirable rates, suggest the maximum possible compromise in balancing the resources between cancer screening and pandemic measures. Moreover, they also indicate the minimum target for shifting to fecal immunochemical test-focused program. Further explorations with varied CRCS settings are necessary for verification.

A First Year Engineering Information Literacy Workshop: Redesigned for Remote Delivery

This paper presents an update of analysis and lessons learned in a required first-year engineering curriculum at a medium sized private urban university. Over the last two years, Research & Instruction librarians at Northeastern University partnered with the First Year Engineering program to develop and refine an interactive in-person workshop series designed to introduce new engineering students to key research resources at the start of their degree programs. The program has grown rapidly, serving more than 500 first year engineering students in fall 2019 with positive outcomes including high perceived value by students, high participation rates, and faculty noting improvement in the quality of students' research. When the COVID-19 pandemic forced Northeastern University to adopt a hybrid learning model, the team redesigned the workshop for remote delivery with the goal of maintaining high participation rates and positive student outcomes. This paper (1) Describes how the workshop was redesigned, including the process and new workshop format which included an asynchronous module delivered via Canvas, followed by a live Zoom class meeting. (2) Compares the outcomes of the online workshops delivered in fall 2020 with the outcomes of the previous in-person workshops to assess the impact of the new delivery mode. (3) Shares lessons learned and considers opportunities to improve remote design and delivery of such workshops in the future. Findings for the redesigned workshop indicate positive outcomes consistent with the in-person workshops, including measures such as attendance rates, assessment scores, students' perceived value, and faculty survey feedback on the quality of students' research. Students found slightly more value in the synchronous class meeting (81.8% rated it extremely or very valuable) than in the asynchronous module (72.8% extremely or very valuable). Students also made suggestions for improvements, such as providing more time for in-class assessment items to provide more hands-on search practice, which they found engaging, and to account for technical issues that slowed them down, such as Internet lag and navigating multiple windows. Other lessons learned include planning for the significant time and effort it takes to redesign a workshop for a new delivery mode, to simplify implementation wherever possible, and that engagement needs to be much more intentional in the online environment. Overall, given the limited timeframe in which to redesign the workshop and challenging circumstances for all, achieving parity with last year's outcomes indicates that in its new format, the workshop is still providing first year students with the foundational research skills they'll need to be successful in their academic and professional careers as engineers. © American Society for Engineering Education, 2021

Increasing the effect of a remedial mathematics course by switching to an online format during the COVID-19 crisis: Evidence from a German university

Due to the COVID-19 crisis, many courses have been offered digitally. Using data from n = 1,173 business students participating in a preparatory mathematics course at a German university that covered the same content as in 2018, 2019 and 2020, we examine how students' participation and the effect of the preparatory course changed. The data show that the participation rate has fallen slightly, but students' participation is rather similar to preceding years. Interestingly, students have participated more intensively. There are clear signs of dishonesty in the self-test (use of a calculator) and significant changes in predictors of performance. In particular, the effect of students' engagement in the course on their performance substantially increased. Further, we found a gender gap in performance affecting women. Finally, the data show that digital courses can be as effective as on-campus courses. © The Author(s) 2020.

Current Status of Cardiac Rehabilitation in the Regional Cardiocerebrovascular Centers in Korea.

Regional Cardiocerebrovascular Centers (RCCs)-a Korean government initiative-seek to reduce medical gaps across regions, and their cardiac rehabilitation (CR) programs are expected to model post-acute care for the Korean CR program. Accordingly, this study aimed to evaluate the current status of CR programs in the RCCs. We distributed surveys on the CR condition, activity, and barriers to 12 RCCs in different provinces. The results revealed significant gaps in the annual number of acute myocardial infarction admissions, and CR candidates, capacity, and density across the 12 RCCs. The CR capacity (50-500) and density (0.42-7.36) indicated particularly large gaps. Twelve RCCs had the necessary facilities, equipment and personnel for CR assessments and management, with high CR referral (97%) and patient education (78%) rates. However, the inpatient CR exercise training (56%) participation rate was inadequate, with much lower enrollment (47%) and adherence (17%) rates to the outpatient CR program and large differences across centers. Therefore, this study's results will provide the evidence required to establish special national health strategies to overcome the CR barriers of patient, doctor/hospital, and policy factors for activating Korean CR programs.

The Danish Health and Wellbeing Survey: Study design, response proportion and respondent characteristics.

AIMS: This study aimed to describe the study design and respondent characteristics (including non-response analyses) of the Danish Health and Wellbeing Surveys in 2015 and 2019 and a follow-up survey that was carried out during the COVID-19 pandemic in 2020. METHODS: The Danish Health and Wellbeing Survey is the Danish part of the European Health Interview Survey (EHIS). The samples in 2015 (N=12,000) and 2019 (N=14,000) were both based on a simple random selection of individuals aged ⩾15 years from the Danish Civil Registration System. All individuals from the sample in 2019 who were still alive and living in Denmark were reinvited for a follow-up survey in 2020 (N=13,474). Data in all surveys were collected via self-administered questionnaires (web or paper based). The questionnaires in 2015 and 2019 included the EHIS model questionnaire as well as national questions, whereas the questionnaire in 2020 mainly focused on physical and mental health, employment and working lives, and health behaviour. RESULTS: The overall response proportion declined slightly between 2015 (48.4%) and 2019 (47.4%) but went up to 49.8% in the follow-up survey in 2020. Unit non-response was associated with, for example, male sex, younger age, being unmarried and lower educational level but not with degree of urbanisation. In all, 5000 individuals completed the questionnaire in both 2019 and 2020. CONCLUSIONS: The results are in line with most previous research on non-response in health surveys. However, an association between degree of urbanisation and non-response has been suggested in previous studies. This association was not found in our study.
