Decrease In Willingness Research Articles

Public perspectives on increased data sharing in health research in the context of the 2023 National Institutes of Health Data Sharing Policy.

The National Institutes of Health (NIH) is the largest public research funder in the world. In an effort to make publicly funded data more accessible, the NIH established a new Data Management and Sharing (DMS) Policy effective January 2023. Though the new policy was available for public comment, the patient perspective and the potential unintended consequences of the policy on patients' willingness to participate in research have been underexplored. This study aimed to determine: (1) participant preferences about the types of data they are willing to share with external entities, and (2) participant perspectives regarding the updated 2023 NIH DMS policy. A cross-sectional, nationally representative online survey was conducted among 610 English-speaking US adults in March 2023 using Prolific. Overall, 50% of the sample identified as women, 13% as Black or African American, and 7% as Hispanic or Latino, with a mean age of 46 years. The majority of respondents (65%) agreed with the NIH policy, but racial differences were noted with a higher percentage (28%) of Black participants indicating a decrease in willingness to participate in research studies with the updated policy in place. Participants were more willing to share research data with healthcare providers, yet their preferences for data sharing varied depending on the type of data to be shared and the recipients. Participants were less willing to share sexual health and fertility data with health technology companies (41%) and public repositories (37%) compared to their healthcare providers (75%). The findings highlight the importance of adopting a transparent approach to data sharing that balances protecting patient autonomy with more open data sharing.

Public's perspective on COVID-19 adenovirus vector vaccines after thrombosis with thrombocytopenia syndrome (TTS) reports and associated regulatory actions – A cross-sectional study in six EU member states

ObjectiveIn 2021, thrombosis with thrombocytopenia syndrome (TTS) was confirmed by the European Medicines Agency (EMA) as a rare side effect of the COVID-19 adenovirus vector vaccines Vaxzevria® and Jcovden®. This study aimed to describe the public’s knowledge of TTS and how it affected the willingness to be vaccinated with COVID-19 vaccines and other vaccines in six European countries. MethodsFrom June to October of 2022, a multi-country cross-sectional online survey was conducted in Denmark, Greece, Latvia, Netherlands, Portugal, and Slovenia. The minimum target of participants to be recruited was based on the size of the country’s population. The results were analysed descriptively. ResultsIn total, 3794 respondents were included in the analysis; across the six countries, 33.3 %–68.3 % reported being familiar with signs and symptoms of TTS, although 3.1–61.4 % of those were able to identify the symptoms correctly. The reported changes in willingness to be vaccinated against COVID-19 and with other vaccines varied per country. The largest reported change in the willingness to be vaccinated with Vaxzevria® and Jcovden® was observed in Denmark (61.2 %), while the willingness to be vaccinated with other COVID-19 vaccines changed most in Slovenia (30.4 %). The smallest decrease in willingness towards future vaccination against COVID-19 was reported in the Netherlands (20.9 %) contrasting with the largest decrease observed in Latvia (69.1 %). ConclusionKnowledge about TTS seemed to have influenced the public’s opinion in Europe resulting in less willingness to be vaccinated with Vaxzevria® and Jcovden®. Willingness for vaccination against COVID-19 with other vaccines and widespread use of vaccines to prevent other diseases also differed and seemed to be determined by the approaches taken by national health authorities when reacting to and communicating about COVID-19 vaccination risks. Further investigation of optimal risk communication strategies is warranted.

Tendency to Consume Anabolic Steroids and Body-Building Supplements in the General Population: An Ecological Study

Background: Anabolic steroids and bodybuilding supplements are products that are readily available in the market and are increasingly being used by young people and athletes. This trend has become a social issue worldwide. Objectives: The purpose of this study is to examine and determine the changes in the prevalence and trends of anabolic steroid usage in Iran. Methods: This ecological study utilized the Google Trends database as its primary source. Initially, we searched for specific keywords related to "anabolic steroids (AS)", "Body-building supplements (BBS)", and "COVID-19" among all searches conducted using GTs from January 2017 to December 2022. Subsequently, Spearman's correlation coefficient was employed to assess the association between the keywords "AS" and "BBS" with the term "COVID-19" during various years. Results: The preference for consuming protein (58.19 ± 15.24) was highest among BBS, while recovery (12.14 ± 17.09) was the lowest. In the case of AS, the highest search frequency was related to Testosterone (56.64 ± 9.57), while the lowest was related to Primobolan (13.72 ± 8.21). In early 2020, we observed a significant impact of the COVID-19 pandemic on the inclination to use BBS and AS, leading to a substantial decrease in willingness to use. However, we did not observe a statistically significant correlation between keyword searches for COVID-19 and AS & BBS. Conclusions: The trend of AS and BBS usage in Iran is on the rise. The indiscriminate use of supplements is a cause for concern and calls for educational interventions.

Willingness to Pay for Universal Health Coverage among the General Population in Armenia

Abstract Background In Armenia, as in many low and middle-income countries, a large segment of the population is still required to make high out-of-pocket payments to obtain essential services at the secondary or tertiary levels of healthcare. Countries are showing growing interest to provide financial protection to their citizens via a universal health coverage system. We assessed the willingness to pay for universal health coverage (UHC) among the general population of Armenia, and the factors that influence their willingness to pay. Methods We administered a national telephone survey (random digit dialing), among the adult population (18-65 years old) of Armenia. Multivariable logistic regression was applied to analyze the data. Results The total number of survey participants was 787 with a 67% response rate. The mean age of the study participants was 41, and 55% of them were women. The majority of participants (60%) were employed. Around 45% of participants had an average monthly expenditure below AMD 200,000 (about USD 510) and more than one-third (36%) of participants had an average monthly income below AMD 200,000. The majority (72%) of participants were willing to pay 2%−6% of their monthly income to obtain UHC. Multivariable logistic regression analysis showed that one year increase in participants’ age was associated with a small decrease in willingness to pay (OR = 0.97, CI = 0.96; 0.99). Participants with an average monthly expenditure of more than AMD 200,000 (about USD 510) were about 3.4 times more likely to pay 2%−6% of their monthly income than those with an average monthly expenditure of less than AMD 200,000 (OR = 3.44, CI = 1.63; 7.30). Conclusions UHC could be a viable solution for improved healthcare access; however, socioeconomic factors influence public readiness to pay for it. To successfully implement a UHC system, governments need to design progressive premium contributions providing more subsidies to lower socioeconomic groups of their populations. Key messages • Socioeconomic factors of a population can impact their willingness to pay for a universal health coverage system. • Governments must tailor premium contribution to UHC systems to the socioeconomic composition of their populations and implement progressive contribution approaches.

How much are patients willing to pay for spine surgery? An evaluation of attitudes toward out-of-pocket expenses and cost-reducing measures

Background ContextWith rising healthcare expenditures in the United States, patients and providers are searching to maintain quality while reducing costs. PurposeThe aim of this study was to investigate patient willingness to pay for anterior cervical discectomy and fusion (ACDF), degenerative lumbar spinal fusions (LF), and adult spine deformity (ASD) surgery. Study Design/SettingA survey was developed and distributed to anonymous respondents through Amazon Mechanical Turk (MTurk). MethodsThe survey introduced 3 procedures: ACDF, LF, and ASD surgery. Respondents were asked sequentially if they would pay at each increasing price option. Respondents were then presented with various cost-saving methods and asked to select the options that made them most uncomfortable, even if those would save them out-of-pocket costs. ResultsIn total, 979 of 1,172 total responses (84%) were retained for analysis. The average age was 36.2 years and 44% of participants reported a household income of $50,000 to 100,000. A total of 63% used Medicare and 13% used Medicaid. A total of 40% stated they had high levels of financial stress. A total of 30.1% of participants were willing to undergo an ACDF, 30.3% were willing to undergo a LF, and 29.6% were willing to undergo ASD surgery for the cost of $3,000 (p=.98). Regression demonstrated that for ACDF surgery, a $100 increase in price resulted in a 2.1% decrease in willingness to pay. This is comparable to degenerative LF surgery (1.8% decrease), and ASD surgery (2%). When asked which cost-saving measures participants were least comfortable with for ACDF surgery, 60% stated “Use of the older generation implants/devices” (LF: 51%, ASD: 60%,), 61% stated “Having the surgery performed at a community hospital instead of at a major academic center” (LF: 49%, ASD: 56%), and 55% stated “Administration of anesthesia by a nurse anesthetist” (LF: 48.01%, ASD: 55%). Conversely, 36% of ACDF patients were uncomfortable with a “Video/telephone postoperative visit” to cut costs (LF: 51%, ASD: 39%). ConclusionSPatients are unwilling to contribute larger copays for adult spinal deformity correction than for ACDF and degenerative lumbar spine surgery, despite significantly higher procedural costs and case complexity/invasiveness. Patients were most uncomfortable forfeiting newer generation implants, receiving the operation at a community rather than an academic center, and receiving care by physician extenders. Conversely, patients were more willing to convert postoperative visits to telehealth and forgo neuromonitoring, indicating a potentially poor understanding of which cost-saving measures may be implemented without increasing the risk of complications.

Does willingness to care fluctuate over time? A weekly diary study among informal caregivers.

Informal caregivers are expected to be willing to care for relatives with care needs. Little is known about whether and how willingness to care changes over time. Using a weekly diary study, we examined changes in the willingness of 955 caregivers from nine countries. Caregivers provided information on their caregiving context, relationship type, and relationship satisfaction with the care recipient. For 24 consecutive weeks, caregivers evaluated willingness to care as it was 'right now'. Willingness differs from one caregiver to another (68% between-level variability) but also fluctuates in the same caregiver from week to week (32% within-level variability), with a decrease over 6 months (intercept = 8.55; slope = -0.93; p < .001). Regardless of individual differences in average willingness to care based on caregiving context and relationship satisfaction, caregivers reported decreases in willingness. Caregivers who presented one or more health conditions themselves reported higher weekly fluctuations in willingness than caregivers with no health conditions. Willingness is not a stable attitude because it decreases and caregivers experience fluctuations from week to week. A clearer understanding of weekly processes is optimal for monitoring the caregivers' well-being and tailoring interventions in line with weekly individual variations.

Political risk and corporate international supply chain

This paper examines the effect of countries’ political risk on corporate international supply chain. Using the survey data of firms in 32 countries, we find that political risk decreases firms’ purchasing proportion from foreign suppliers. We also find that the effect is less pronounced for firms with business association membership and whose main market is international, and firms in countries with better institutional environments and higher degree of development. Studies on influencing channels show that political risk decreases corporate international purchasing through the increase in corporate informal payments and the decrease in willingness to apply for import licenses. Finally, we find that the reduced corporate international purchasing accompanied by political risk decreases firms’ capacity utilization, expected sales, and research and development activities. Collectively, our findings provide new evidence on the role of political risk for firms’ international purchasing decisions.

Testing the efficacy of real-time fMRI neurofeedback for training people who smoke daily to upregulate neural responses to nondrug rewards.

Although the use of nondrug rewards (e.g., money) to facilitate smoking cessation is widespread, recent research has found that such rewards may be least effective when people who smoke cigarettes are tempted to do so. Specifically, among people who smoke, the neural response to nondrug rewards appears blunted when access to cigarettes is anticipated, and this blunting is linked to a decrease in willingness to refrain from smoking to earn a monetary incentive. Accordingly, methods to enhance the value of nondrug rewards may be theoretically and clinically important. The current proof-of-concept study tested if real-time fMRI neurofeedback training augments the ability to upregulate responses in reward-related brain areas relative to a no-feedback control condition in people who smoke. Adults (n = 44, age range = 20-44) who reported smoking >5 cigarettes per day completed the study. Those in the intervention group (n = 22, 5 females) were trained to upregulate brain responses using feedback of ongoing striatal activity (i.e., a dynamic "thermometer" that reflected ongoing changes of fMRI signal intensity in the striatum) in a single neurofeedback session with three training runs. The control group (n = 22, 5 females) underwent a nearly identical procedure but received no neurofeedback. Those who received neurofeedback training demonstrated significantly greater increases in striatal BOLD activation while attempting to think about something rewarding compared to controls, but this effect was present only during the first training run. Future neurofeedback research with those who smoke should explore how to make neurofeedback training more effective for the self-regulation of reward-related brain activities.

Pharmacists' Perceptions of Mental Well-Being and Immunization Safety During COVID-19.

Purpose: To assess pharmacists' mental well-being, perceptions of safety, and willingness to administer vaccines before and during the COVID-19 pandemic. Methods: An electronic survey was administered to a convenient sample of practicing pharmacists working in Alabama, Tennessee and Texas. The 33-item survey examined pharmacists' beliefs about the pandemic's impact on their mental well-being, their perceptions of safety in vaccine administration, and their willingness to vaccinate. Responses were assessed on a 5-point Likert scale, ranging from strongly disagree (1) to strongly agree (5). A recruitment email with the survey link was sent to pharmacists, with periodic reminders over a 4-week period. Descriptive statistics and bivariate analyses were utilized to evaluate survey responses. Results: A total of 387 responses were analyzed, with an estimated response rate of 3.93%. Most respondents were women (65%) and had at least 6 to 10 years of practice experience (28%). Overall, participants felt that the pandemic worsened their mental well-being, with women reporting a more negative mental well-being compared with men (P < .001). They reported having less time during workflow to apply personal protective equipment (PPE) (P = .0074) compared to before the pandemic. They also reported a decrease in willingness to vaccinate adult patients during the pandemic (P < .0001), and that concern about contracting COVID-19 prevented them from giving vaccinations (P < .0001). Conclusions: Pharmacists felt their mental well-being and willingness to vaccinate patients suffered as a result of the COVID-19 pandemic. Future research and initiatives that focus on improving vaccination rates should also consider pharmacists' concerns and well-being.

Social norms (not threat) mediate willingness to sacrifice in individuals fused with the nation: Insights from the COVID-19 pandemic.

Identity fusion with the community has been previously found to mediate altruism in post‐disaster settings. However, whether this altruistic response is specifically triggered by ingroup threat, or whether it can also be triggered by global threats remains unclear. We evaluated willingness to sacrifice in the context of the COVID‐19 pandemic across three survey waves. Against expectations, participants fused with the nation (vs. non‐fused) did not differentially respond to a national versus global threat condition. Conversely, social norms decisively influenced willingness to sacrifice in this sample, with fused individuals with stronger norms about social distancing reporting the highest altruistic response during the first weeks of the pandemic. Longitudinally, after an initial peak in the altruistic response, deteriorating social norms mediated decreases in willingness to sacrifice in individuals fused with the nation (vs. non‐fused). Implications of these results for the development of interventions aimed to address global challenges are discussed.

Prevalence of postpartum depression and antenatal anxiety symptoms during COVID-19 pandemic: An observational prospective cohort study in Greece.

INTRODUCTIONA significant proportion of pregnant women and women in the early postpartum period suffer from mental health problems. The COVID-19 pandemic represents a unique stressor during this period and many studies across the world have shown elevated rates of postpartum depression (PPD).METHODSIn this multicenter two-phase observational prospective cohort study, we aim to assess the prevalence of anxiety prior to labor (Generalized Anxiety Disorder-7), as well as PPD at 6–8 weeks postpartum using the Edinburgh Postnatal Depression Scale (EPDS).RESULTSOf the 330 women analyzed, 13.2% reported symptoms of depression using EPDS cut-off score ≥13. High antenatal levels of anxiety (24.8% scored ≥10 in GAD-7) were documented. A significant proportion of postpartum women reported a decrease in willingness to attend antenatal education courses (36%) and fewer antenatal visits to their obstetrician (34%) due to pandemic. Higher antenatal anxiety increased the odds of being depressed at 6–8 weeks postpartum (EPDS ≥13).CONCLUSIONSCompared to reported prevalence of PPD from previous studies before the COVID-19 era in Greece, we did not find elevated rates during the first wave of the pandemic. High anxiety levels were observed indicating that there is a need for close monitoring in pregnancy during the pandemic and anxiety screening to identify women who need support in the pandemic era. A well-planned maternity program should be employed by all the associated care providers to maintain the proper antenatal care adjusted to the pandemic strains as well as a follow-up after labor.

Knowledge, Attitudes, and Beliefs of Pediatric Health Care Workers: Understanding the Response to COVID-19.

IntroductionThis research aims to assess knowledge, attitudes, and beliefs of PHCW regarding COVID-19.MethodData collected using an electronic survey sent to pediatric health care workers.ResultsAge was not likely to influence willingness to care for patients with COVID-19. Males were more likely to be willing to care for patients than female. Nurse practitioners were more likely to be willing to care for patients with COVID-19 than physicians. Availability of proper personal protective equipment, COVID-19 knowledge, and training did not influence willingness to care for COVID-19 patients. Healthcare workers with a higher risk of COVID-19-related sickness, and who received most of their COVID-19 information from social media, were less likely to be willing to care for COVID positive patients. As perception of hospital preparedness increased, reluctance to care for COVID-19 positive patients decreased.DiscussionHospital preparedness and social media exposure play a significant role in willingness to care for patients with COVID-19.

The Future Capacity of the Nursing Workforce: COVID-19 Pandemic's Impacts on New Nurses and Nursing Students Toward the Profession.

Nurses are concerned for their safety and conflicted about their career, because their duty to care for patients during the pandemic involved competing ethical obligations, including their own personal safety. The aim was to explore the impact of COVID-19 on new nurses and nursing students in terms of safety and interest in nursing specifically related to self-efficacy, geographic region case density, and frontline experience in health care. New nurses and nursing students (N = 472) responded to an online survey examining self-efficacy, sense of safety, and interest in nursing. The survey included an open-ended question to support response interpretation. Researchers identified significant differences among new nurses and students from contrasting case-dense regions in terms of safety and interest in nursing. Concerns about personal safety and the safety of others were apparent. Over time, this may lead to a decrease in willingness to enter or remain in the nursing profession.

Pengaruh Pendapatan, Pengetahuan Dan Kerentanan Penyakit Terhadap Willingness To Pay (WTP) Premi Jaminan Kesehatan Pada Pekerja Sektor Informal

&#x0D; Background:&#x0D; The Indonesian Government's target of Universal Coverage or 100% Health Insurance participation by 2019 failed to be achieved, even until the end of October 2020. The failure of universal coverage resulted in BPJS Health's finances getting worse after experiencing a deficit. Informal sector workers are the most dominant sector that has not participated in the Health Insurance scheme, totaling 30,487,891 workers. Low income, uncertainty each month, and the increase in contributions resulted in a decrease in Willingness to pay Health Insurance contributions.&#x0D; Research purposes:&#x0D; The purpose of this study is to analyze the effect of income, knowledge, and disease susceptibility to the willingness to pay (WTP) of health insurance contributions to informal sector workers.&#x0D; Method:&#x0D; This cross-sectional research was conducted in Kudus Regency, Central Java in January-February 2020. Sampling used purposive sampling with a total of 200 informal sector workers who had not yet participated in BPJS Kesehatan. The dependent variable is a willingness to pay. The independent variables are income, knowledge, and disease susceptibility. Data collection using a questionnaire and data analysis with logistic regression.&#x0D; Result:&#x0D; Willingness To Pay health insurance contributions for informal sector workers increased in income ≥Rp 2,218,451 (b = 2.02; 95% CI = 1.01-3.55; p = 0.044), high knowledge (b = 4.64; 95% CI = 2.36-8.31; p &lt;0.001), high disease susceptibility (b = 3.01; 95% CI = 0.26-5.75; p = 0.031).&#x0D; Conclusion:&#x0D; Income, knowledge, and disease vulnerability have a significant effect on the willingness to pay for health insurance contributions for informal sector workers.&#x0D; &#x0D; Keywords: Universal Health Coverage; Willingness To Pay; Health Insurance; informal sector workers.

Rates of exposure to natural, accidental, and suicide deaths.

We expand upon previous research examining the prevalence of exposure to suicide deaths by comparing these to natural and accidental deaths. Furthermore, we examine whether participants are more apt to lie about the cause of death for a suicide than for an accidental or natural death. The sample consisted of 1,430 respondents who were recruited via Amazon's Mechanical Turk to complete an online study. Participants completed measures to assess exposure to death, causes of death, and willingness to disclose the cause of death to others. Nearly all respondents (94.5%) had been exposed to a natural death, and most of our sample (63.2%) reported exposure to a suicide death. Among those affected by all three causes of death, RANOVA analysis also indicated that people lied about cause of suicide death to significantly more people than accidental or natural. Overall, the current study presents updated prevalence rates of exposure to various types of death and replicates previous findings of a decrease in willingness to disclose suicides when compared with other causes of death.

Knowledge and attitudes of Vietnamese high school students towards cardiopulmonary resuscitation: Results from a pilot student-led cross-country bystander training workshop

Objectives: This is a first-of-its-kind cross-country collaboration between medical students from Singapore and Vietnam in conducting a cardiopulmonary resuscitation (CPR) workshop for Vietnamese high school students. Our objective was to assess the effectiveness of CPR training in improving students’ knowledge and attitudes towards CPR. Methods: The CPR workshop was conducted using active learning methods, including interactive lecture session, games, small group demonstration and hands-on practice on the mannequin. Knowledge and attitudes towards CPR were studied using a standardised questionnaire administered at three time points: before the workshop (TP1), immediately after the workshop (TP2) and three months after the workshop (TP3). Results: There was an improvement in the median knowledge score from 6.5/14 at TP1 to 13/14 at TP2 ( p&lt;0.001) which was sustained at TP3 (10/14). Willingness and confidence in performing CPR on strangers increased from TP1 to TP2. From TP2 to TP3, however, there was a decrease in willingness to perform CPR on all groups, though confidence in performing CPR remained high at TP3. The most-cited concern about performing CPR was a lack of skills and knowledge. Most participants picked formal training courses to increase confidence in performing CPR. Conclusions: The CPR training was effective in improving the knowledge and attitudes of high school students towards CPR. Our study supports expanding this workshop to train more students in basic cardiac life support in the community and further collaboration internationally between medical schools in order to increase the number of students in the community competent in performing CPR.

Administrative Burdens and Citizen Likelihood to Seek Local Public Services: The Case of Hurricane Shelters

Drawing on the theory of administrative burdens, we assess how a variety of rules surrounding access to public hurricane shelters influences residents’ likelihood of using this service. We employ three experiments embedded in an online survey, in which we vary the requirements regarding public safety and pets, common at shelters, which could create burdens for residents seeking to access shelters. Our results suggest that residents are more likely to make use of shelters when rules require shelters be staffed by local or state police. However, rules requiring police to check shelter-goers for outstanding warrants or sex-offender registration do not impact the likelihood of going to a shelter. Finally, rules forbidding pets lead to a significant decrease in willingness to evacuate to a shelter. In short, some administrative burdens surrounding access to hurricane shelters may have a significant impact on the degree to which residents seek access to shelters during hazards.

Consumer Reactions to E. Coli and Antibiotic Residue Recalls: Utility Maximization vs. Regret Minimization.

Food safety remains a major issue to many consumers. Previous studies examining the economic impact of food safety recalls have focused on Class I recalls. Antibiotic residue in meat products, a Class II recall, has increased in consumer importance yet little is known about how much research and development expenditure should be allocated to reduce antibiotic residue pre- and post-harvest. This study compares demand elasticities and the decrease in willingness to pay in response to either an E. coli (Class I) or antibiotic residue (Class II) recall. We compare and contrast two competing behavioral frameworks, Random Utility and Regret Minimizing. Modeling behavior using the random regret framework is found to be more powerful for assessing consumer responses. In addition, we explore if different groups of consumers exist that either maximize utility or minimize regret. Consumer devaluations of E. coli (Class I) are 40–65% larger than antibiotic residue (Class II). Approximately 60% of consumers are identified as regret minimizers and 40% were identified as utility maximizers. While industry response and government policy recommendations differed conditional on modeling framework, the regret minimizing framework required smaller price discounts than regret minimizing to maintain the same level of market share.

Partisan in-group bias before and after elections

Partisan attachment is a major source of group identity in democracies, accounting for a strong in-group bias when citizens make judgments on trust, cooperation, and resource sharing. Yet what factors condition behavioural expressions of partisan in-group bias are not well-understood. Here, I explore the impact of one theoretically-critical factor - election cycles - in fueling partisan-based discrimination and favouritism. Using an experiment embedded in a panel study fielded immediately before and after the 2015 Canadian federal election, I find that pre-election in-group bias levels were cut by a full third within two days of election day. The bulk of the decline is explained by a decrease in willingness to discriminate against out-partisans, while co-partisan favouritism levels remain stable. Further, in-group bias substantially decreases post-election among supporters of gaining parties and among strategic voters, while losing party supporters and sincere voters continued to express it strongly. I discuss theoretical implications on our current, static understanding of partisan-based discriminatory behaviour.
