Did people really drink bleach to prevent COVID-19? A guide for protecting survey data against problematic respondents.

Survey respondents who are non-attentive, respond randomly, or misrepresent who they are can impact the outcomes of surveys. Prior findings reported by the CDC have suggested that people engaged in highly dangerous cleaning practices during the COVID-19 pandemic, including ingesting household cleaners such as bleach. In our attempts to replicate the CDC's results, we found that 100% of reported ingestion of household cleaners are made by problematic respondents. Once inattentive, acquiescent, and careless respondents are removed from the sample, we find no evidence that people ingested cleaning products to prevent a COVID-19 infection. These findings have important implications for public health and medical survey research, as well as for best practices for avoiding problematic respondents in all survey research conducted online.

Is it ethical to use Mechanical Turk for behavioral research? Relevant data from a representative survey of MTurk participants and wages.

To understand human behavior, social scientists need people and data. In the last decade, Amazon's Mechanical Turk (MTurk) emerged as a flexible, affordable, and reliable source of human participants and was widely adopted by academics. Yet despite MTurk's utility, some have questioned whether researchers should continue using the platform on ethical grounds. The brunt of their concern is that people on MTurk are financially insecure, subject to abuse, and earn inhumane wages. We investigated these issues with two representative probability surveys of the U.S. MTurk population (N = 4094). The surveys revealed: (1) the financial situation of people on MTurk mirrors the general population, (2) most participants do not find MTurk stressful or requesters abusive, and (3) MTurk offers flexibility and benefits that most people value above other options for work. People reported it is possible to earn more than $10 per hour and said they would not trade the flexibility of MTurk for less than $25 per hour. Altogether, our data are important for assessing whether MTurk is an ethical place for research.

Evaluating CloudResearch's Approved Group as a solution for problematic data quality on MTurk.

Maintaining data quality on Amazon Mechanical Turk (MTurk) has always been a concern for researchers. These concerns have grown recently due to the bot crisis of 2018 and observations that past safeguards of data quality (e.g., approval ratings of 95%) no longer work. To address data quality concerns, CloudResearch, a third-party website that interfaces with MTurk, has assessed ~165,000 MTurkers and categorized them into those that provide high- (~100,000, Approved) and low- (~65,000, Blocked) quality data. Here, we examined the predictive validity of CloudResearch's vetting. In a pre-registered study, participants (N = 900) from the Approved and Blocked groups, along with a Standard MTurk sample (95% HIT acceptance ratio, 100+ completed HITs), completed an array of data-quality measures. Across several indices, Approved participants (i) identified the content of images more accurately, (ii) answered more reading comprehension questions correctly, (iii) responded to reversed coded items more consistently, (iv) passed a greater number of attention checks, (v) self-reported less cheating and actually left the survey window less often on easily Googleable questions, (vi) replicated classic psychology experimental effects more reliably, and (vii) answered AI-stumping questions more accurately than Blocked participants, who performed at chance on multiple outcomes. Data quality of the Standard sample was generally in between the Approved and Blocked groups. We discuss how MTurk's Approval Rating system is no longer an effective data-quality control, and we discuss the advantages afforded by using the Approved group for scientific studies on MTurk.

Do you know the Wooly Bully? Testing era-based knowledge to verify participant age online.

People in online studies sometimes misrepresent themselves. Regardless of their motive for doing so, participant misrepresentation threatens the validity of research. Here, we propose and evaluate a way to verify the age of online respondents: a test of era-based knowledge. Across six studies (N = 1543), participants of various ages completed an age verification instrument. The instrument assessed familiarity with cultural phenomena (e.g., songs and TV shows) from decades past and present. We consistently found that our instrument discriminated between people of different ages. In Studies 1a and 1b, self-reported age correlated strongly with performance on the instrument (mean r = .8). In Study 2, the instrument reliably detected imposters who we knew were misrepresenting their age. For impostors, self-reported age did not correlate with performance on the instrument (r = .077). Finally, in Studies 3a, 3b, and 3c, the instrument remained robust with African Americans, people from low educational backgrounds, and recent immigrants to the United States. Thus, our instrument shows promise for verifying the age of online respondents, and, as we discuss, our approach of assessing "insider knowledge" holds great promise for verifying other identities within online studies.

Paranoia and belief updating during the COVID-19 crisis.

The COVID-19 pandemic has made the world seem less predictable. Such crises can lead people to feel that others are a threat. Here, we show that the initial phase of the pandemic in 2020 increased individuals' paranoia and made their belief updating more erratic. A proactive lockdown made people's belief updating less capricious. However, state-mandated mask-wearing increased paranoia and induced more erratic behaviour. This was most evident in states where adherence to mask-wearing rules was poor but where rule following is typically more common. Computational analyses of participant behaviour suggested that people with higher paranoia expected the task to be more unstable. People who were more paranoid endorsed conspiracies about mask-wearing and potential vaccines and the QAnon conspiracy theories. These beliefs were associated with erratic task behaviour and changed priors. Taken together, we found that real-world uncertainty increases paranoia and influences laboratory task behaviour.

Paranoia and belief updating during a crisis.

The 2019 coronavirus (COVID-19) pandemic has made the world seem unpredictable. During such crises we can experience concerns that others might be against us, culminating perhaps in paranoid conspiracy theories. Here, we investigate paranoia and belief updating in an online sample (N=1,010) in the United States of America (U.S.A). We demonstrate the pandemic increased individuals' self-rated paranoia and rendered their task-based belief updating more erratic. Local lockdown and reopening policies, as well as culture more broadly, markedly influenced participants' belief-updating: an early and sustained lockdown rendered people's belief updating less capricious. Masks are clearly an effective public health measure against COVID-19. However, state-mandated mask wearing increased paranoia and induced more erratic behaviour. Remarkably, this was most evident in those states where adherence to mask wearing rules was poor but where rule following is typically more common. This paranoia may explain the lack of compliance with this simple and effective countermeasure. Computational analyses of participant behaviour suggested that people with higher paranoia expected the task to be more unstable, but at the same time predicted more rewards. In a follow-up study we found people who were more paranoid endorsed conspiracies about mask-wearing and potential vaccines - again, mask attitude and conspiratorial beliefs were associated with erratic task behaviour and changed priors. Future public health responses to the pandemic might leverage these observations, mollifying paranoia and increasing adherence by tempering people's expectations of other's behaviour, and the environment more broadly, and reinforcing compliance.

Psychological Distress Among the First Quarantined Community in the United States: Initial Observations From the Early Days of the COVID-19 Crisis.

This study assesses distress and anxiety symptoms associated with quarantine due to COVID-19 exposure among the first quarantined community in the United States and identifies potential areas of intervention. All participants were directly or peripherally related to "patient 1,"-the first confirmed community-acquired case of COVID-19 in the New York Area. As such, this is a historically significant sample whose experiences highlight a transitional moment from a pre-pandemic to a pandemic period in the United States. In March 2020, an anonymous survey was distributed to 1,250 members of a NYC area community that was under community-wide quarantine orders due to the COVID-19 outbreak. Distress was measured using the Subjective Units of Distress Scale (SUDS) and symptoms of anxiety were measured using the Beck Anxiety Inventory (BAI). A variety of psychosocial predictors relevant to the current crisis were explored. Three hundred and three individuals responded within forty-eight hours of survey distribution. Mean levels of distress in the sample were heightened and sustained, with 69% reporting moderate to severe distress on the SUDS and 53% of the sample reported mild, moderate, or severe anxiety symptoms on the BAI. The greatest percentage of variance of distress and anxiety symptoms was accounted for by modifiable factors amenable to behavioral and psychological interventions.

A Look at the First Quarantined Community in the USA: Response of Religious Communal Organizations and Implications for Public Health During the COVID-19 Pandemic.

The current study examined anxiety and distress among members of the first community to be quarantined in the USA due to the COVID-19 pandemic. In addition to being historically significant, the current sample was unusual in that those quarantined were all members of a Modern Orthodox Jewish community and were connected via religious institutions at which exposure may have occurred. We sought to explore the community and religious factors unique to this sample, as they relate to the psychological and public health impact of quarantine. Community organizations were trusted more than any other source of COVID-19-related information, including federal, state and other government agencies, including the CDC, WHO and media news sources. This was supported qualitatively with open-ended responses in which participants described the range of supports organized by community organizations. These included tangible needs (i.e., food delivery), social support, virtual religious services, and dissemination of COVID-19-related information. The overall levels of distress and anxiety were elevated and directly associated with what was reported to be largely inadequate and inconsistent health-related information received from local departments of health. In addition, the majority of participants felt that perception of or concern about future stigma related to a COVID-19 diagnosis or association of COVID-19 with the Jewish community was high and also significantly predicted distress and anxiety. The current study demonstrates the ways in which religious institutions can play a vital role in promoting the well-being of their constituents. During this unprecedented pandemic, public health authorities have an opportunity to form partnerships with religious institutions in the common interests of promoting health, relaying accurate information and supporting the psychosocial needs of community members, as well as protecting communities against stigma and discrimination.

The persistence of pay inequality: The gender pay gap in an anonymous online labor market.

Studies of the gender pay gap are seldom able to simultaneously account for the range of alternative putative mechanisms underlying it. Using CloudResearch, an online microtask platform connecting employers to workers who perform research-related tasks, we examine whether gender pay discrepancies are still evident in a labor market characterized by anonymity, relatively homogeneous work, and flexibility. For 22,271 Mechanical Turk workers who participated in nearly 5 million tasks, we analyze hourly earnings by gender, controlling for key covariates which have been shown previously to lead to differential pay for men and women. On average, women's hourly earnings were 10.5% lower than men's. Several factors contributed to the gender pay gap, including the tendency for women to select tasks that have a lower advertised hourly pay. This study provides evidence that gender pay gaps can arise despite the absence of overt discrimination, labor segregation, and inflexible work arrangements, even after experience, education, and other human capital factors are controlled for. Findings highlight the need to examine other possible causes of the gender pay gap. Potential strategies for reducing the pay gap on online labor markets are also discussed.

Tapped out or barely tapped? Recommendations for how to harness the vast and largely unused potential of the Mechanical Turk participant pool.

Mechanical Turk (MTurk) is a common source of research participants within the academic community. Despite MTurk's utility and benefits over traditional subject pools some researchers have questioned whether it is sustainable. Specifically, some have asked whether MTurk workers are too familiar with manipulations and measures common in the social sciences, the result of many researchers relying on the same small participant pool. Here, we show that concerns about non-naivete on MTurk are due less to the MTurk platform itself and more to the way researchers use the platform. Specifically, we find that there are at least 250,000 MTurk workers worldwide and that a large majority of US workers are new to the platform each year and therefore relatively inexperienced as research participants. We describe how inexperienced workers are excluded from studies, in part, because of the worker reputation qualifications researchers commonly use. Then, we propose and evaluate an alternative approach to sampling on MTurk that allows researchers to access inexperienced participants without sacrificing data quality. We recommend that in some cases researchers should limit the number of highly experienced workers allowed in their study by excluding these workers or by stratifying sample recruitment based on worker experience levels. We discuss the trade-offs of different sampling practices on MTurk and describe how the above sampling strategies can help researchers harness the vast and largely untapped potential of the Mechanical Turk participant pool.

Online panels in social science research: Expanding sampling methods beyond Mechanical Turk.

Amazon Mechanical Turk (MTurk) is widely used by behavioral scientists to recruit research participants. MTurk offers advantages over traditional student subject pools, but it also has important limitations. In particular, the MTurk population is small and potentially overused, and some groups of interest to behavioral scientists are underrepresented and difficult to recruit. Here we examined whether online research panels can avoid these limitations. Specifically, we compared sample composition, data quality (measured by effect sizes, internal reliability, and attention checks), and the non-naivete of participants recruited from MTurk and Prime Panels-an aggregate of online research panels. Prime Panels participants were more diverse in age, family composition, religiosity, education, and political attitudes. Prime Panels participants also reported less exposure to classic protocols and produced larger effect sizes, but only after screening out several participants who failed a screening task. We conclude that online research panels offer a unique opportunity for research, yet one with some important trade-offs.

Both Intrinsic and Extrinsic Religious Orientation are Positively Associated with Attitudes Toward Cleanliness: Exploring Multiple Routes from Godliness to Cleanliness.

In the present study, we explore how intrinsic and extrinsic religious orientations are associated with cleanliness attitudes. We find that reported importance of religion is associated with increased cleanliness concerns and interest in cleanliness. Attitudes toward cleanliness were also associated with both intrinsic religious orientation and extrinsic religious orientation. Together, religiosity and religious orientation account for 14.7% of cleanliness attitudes and remained significant in the presence of personality, socioeconomic status, age, education, obsessive-compulsive attitudes toward cleanliness, and other covariates. These results show that religiosity is associated with cleanliness via multiple routes. We suggest that intrinsic religious orientation leads to increased interest in cleanliness due to the link between physical and spiritual purity. Extrinsic religious orientation may be linked with cleanliness because of the secondary benefits, including health and the facilitation in communal cohesiveness, that cleanliness rituals offer. The implications of these findings for the relationship between religion and health are discussed.

Racial Disparities in Cleanliness Attitudes Mediate Purchasing Attitudes Toward Cleaning Products: a Serial Mediation Model.

The present study has three objectives (1) to examine whether there are differences in cleanliness concerns between African Americans and European Americans toward kitchen items that are known to be vectors of disease, (2) to examine whether disparities in cleanliness attitudes have an impact on purchasing attitudes toward kitchen cleaning products, and (3) to explore the mechanisms that may account for these differences utilizing a serial mediation model. Five hundred participants, 50% African American and 50% European American were shown a picture of a sponge cleaning product and filled out multiple survey instruments relating to cleanliness attitudes. We found greater concern with cleanliness of kitchen items (d = .46) and a greater willingness to purchase cleaning products among African Americans compared to European Americans (17 vs 10%). A serial mediation analysis revealed that general cleanliness concerns account for the increased willingness to spend money on cleaning products among African Americans. These results suggest that African Americans are more sensitive to issues of cleanliness compared to European Americans and, in particular, are more sensitive to cleanliness of kitchen items such as sponges, which can be vectors of food-borne pathogens. Potential reasons for the observed racial disparities in cleanliness attitudes and the implications of these results for public health are discussed.

Extrinsic Religious Orientation and Disordered Eating Pathology Among Modern Orthodox Israeli Adolescents: The Mediating Role of Adherence to the Superwoman Ideal and Body Dissatisfaction.

The role of religious and spiritual factors has been recognized with regard to risk factors for disordered eating pathology (DEP). Specifically, religious orientation, or underlying religious motivation, has been associated with DEP among a variety of religious groups. Extrinsic religious orientation has consistently been found to be associated with increased levels of DEP among Christians and Jews in the USA. However, this paradigm has not been investigated cross-culturally. The current study is the first to examine the association of extrinsic religious orientation and DEP among Modern Orthodox Israeli adolescents. Furthermore, the mediating mechanisms of adherence to the Superwoman Ideal and body dissatisfaction are explored to further elucidate the mechanisms generating the association between religious orientation and DEP. A sample of 120 Modern Orthodox Israeli adolescent females participated in an anonymous survey which asked about DEP, body dissatisfaction, adherence to the Superwoman Ideal and religious orientation. Mediation models revealed a significant association between extrinsic religious orientation and DEP. Furthermore, adherence to the Superwoman Ideal and body dissatisfaction serially mediated the association between religious orientation and DEP. Findings suggest that a pathway through which extrinsic orientation influences DEP is through greater adherence to the Superwoman Ideal which leads to higher levels of body dissatisfaction, which is known to be a proximal risk factor for DEP. This finding is discussed in light of specific cultural pressures within the Modern Orthodox population and related clinical implications.

Development of the Healthcare Triggering Questionnaire in adult sexual abuse survivors.

OBJECTIVE: One in 4 women and 1 in 10 men in the United States are survivors of sexual abuse (SA). For these survivors, healthcare experiences may trigger memories, thoughts, feelings or sensations related to this past abuse. Such triggering can be associated with negative responses to healthcare (e.g., anxiety, avoidance). However, to date, no healthcare triggering assessment tool exists. Therefore, the study goal was to describe the prevalence of healthcare triggering, to develop a brief Healthcare Triggering Questionnaire (HTQ), and to examine its initial validity. METHOD: An initial pool of 117 items was developed based on previous research. Two-parameter logistic item response theory models were used to develop the scales. SA survivors [male (n = 233), female (n = 222)] and a comparison group of non-SA individuals [male (n = 114), female (n = 106)] were recruited through Amazon Mechanical Turk and completed the study anonymously online. RESULTS: Three 10-item scales were developed: (a) the HTQ-M for males; (b) the HTQ-F for females; and (c) the HTQ-U (unisex) for all respondents. The results supported the utility and initial validity of the gender-specific and unisex scales. CONCLUSIONS: The HTQ scales are a psychometrically sound approach to evaluating healthcare triggering experienced by adult sexual abuse survivors. The HTQ may be considered for use by researchers interested in studying healthcare triggering, healthcare retraumatization, and healthcare adherence. The HTQ may also be of use to clinicians interested in identifying trauma survivors who are more likely to experience triggering in healthcare settings. (PsycINFO Database Record

TurkPrime.com: A versatile crowdsourcing data acquisition platform for the behavioral sciences.

In recent years, Mechanical Turk (MTurk) has revolutionized social science by providing a way to collect behavioral data with unprecedented speed and efficiency. However, MTurk was not intended to be a research tool, and many common research tasks are difficult and time-consuming to implement as a result. TurkPrime was designed as a research platform that integrates with MTurk and supports tasks that are common to the social and behavioral sciences. Like MTurk, TurkPrime is an Internet-based platform that runs on any browser and does not require any downloads or installation. Tasks that can be implemented with TurkPrime include: excluding participants on the basis of previous participation, longitudinal studies, making changes to a study while it is running, automating the approval process, increasing the speed of data collection, sending bulk e-mails and bonuses, enhancing communication with participants, monitoring dropout and engagement rates, providing enhanced sampling options, and many others. This article describes how TurkPrime saves time and resources, improves data quality, and allows researchers to design and implement studies that were previously very difficult or impossible to carry out on MTurk. TurkPrime is designed as a research tool whose aim is to improve the quality of the crowdsourcing data collection process. Various features have been and continue to be implemented on the basis of feedback from the research community. TurkPrime is a free research platform.

Mobile Exercise Apps and Increased Leisure Time Exercise Activity: A Moderated Mediation Analysis of the Role of Self-Efficacy and Barriers.

BACKGROUND: There are currently over 1000 exercise apps for mobile devices on the market. These apps employ a range of features, from tracking exercise activity to providing motivational messages. However, virtually nothing is known about whether exercise apps improve exercise levels and health outcomes and, if so, the mechanisms of these effects. OBJECTIVE: Our aim was to examine whether the use of exercise apps is associated with increased levels of exercise and improved health outcomes. We also develop a framework within which to understand how exercise apps may affect health and test multiple models of possible mechanisms of action and boundary conditions of these relationships. Within this framework, app use may increase physical activity by influencing variables such as self-efficacy and may help to overcome exercise barriers, leading to improved health outcomes such as lower body mass index (BMI). METHODS: In this study, 726 participants with one of three backgrounds were surveyed about their use of exercise apps and health: (1) those who never used exercise apps, (2) those who used exercise apps but discontinued use, and (3) those who are currently using exercise apps. Participants were asked about their long-term levels of exercise and about their levels of exercise during the previous week with the International Physical Activity Questionnaire (IPAQ). RESULTS: Nearly three-quarters of current app users reported being more active compared to under half of non-users and past users. The IPAQ showed that current users had higher total leisure time metabolic equivalent of task (MET) expenditures (1169 METs), including walking and vigorous exercise, compared to those who stopped using their apps (612 METs) or who never used apps (577 METs). Importantly, physical activity levels in domains other than leisure time activity were similar across the groups. The results also showed that current users had lower BMI (25.16) than past users (26.8) and non-users (26.9) and that this association was mediated by exercise levels and self-efficacy. That relationship was also moderated by perceived barriers to exercise. Multiple serial mediation models were tested, which revealed that the association between app use and BMI is mediated by increased self-efficacy and increased exercise. CONCLUSIONS: Exercise app users are more likely to exercise during their leisure time, compared to those who do not use exercise apps, essentially fulfilling the role that many of these apps were designed to accomplish. Data also suggest that one way that exercise apps may increase exercise levels and health outcomes such as BMI is by making it easier for users to overcome barriers to exercise, leading to increased self-efficacy. We discuss ways of improving the effectiveness of apps by incorporating theory-driven approaches. We conclude that exercise apps can be viewed as intervention delivery systems consisting of features that help users overcome specific barriers.

Relationship Between Peer Victimization and Posttraumatic Stress Among Primary School Children.

Peer victimization is a common stressor experienced by children. Although peer victimization has been studied extensively, few studies have examined the potential link between peer victimization and posttraumatic stress disorder (PTSD), and no studies of which we are aware have examined this link among children in primary school. The paucity of studies examining the link between PTSD and peer victimization in primary school is surprising because peer victimization occurs more frequently and is more likely to be physical among 7- and 8-year-old children. This study assessed the relationship between peer victimization and PTSD in a sample of 358 elementary school children (ages 6-11 years). Results indicated that peer victimization accounted for 14.1% of PTSD symptom severity among boys and 10.1% among girls. Additionally, we found gender differences in the types of peer victimization that were most associated with PTSD symptom severity (d = 0.38). The long-term developmental consequences that may be associated with peer victimization-linked PTSD symptomatology are discussed.

The Effect of Combined Ultrasound and Electric Field Stimulation on Wound Healing in Chronic Ulcerations.

INTRODUCTION: Ultrasound and electric stimulation are known therapies for the treatment of chronic ulcerations. Combined modulated ultrasound and electric field stimulation (CUSEFS) have never been studied as a single modality. The authors evaluate the results of CUSEFS (BRH Medical Ltd, Jerusalem, Israel) on a variety of wound types in a number of clinics. METHODS: This retrospective analysis looked at ulcers treated with CUSEFS in 4 clinics. Wounds were evaluated by an independent assessor and data was evaluated by an independent statistician. Of the 300 wounds treated with the CUSEFS device, only those classified as diabetic foot ulcers (DFUs) or venous leg ulcers (VLUs) were evaluated. A treatment was deemed successful if the wound was 50% closed within 4 weeks. Subjects were then followed to see if their wounds completely closed within 16 weeks. RESULTS: Of the 27 DFUs treated, 59.3% (16) achieved 50% closure within 4 weeks. Of the 38 VLUs treated, 71.1% (27) achieved 50% closure within 4 weeks. It was found that variables such as gender, size of the wound at presentation, and longevity of the wound had no bearing on the outcome. The age of the patient had an effect on the outcome of the VLUs. The wound healing trajectory was supported in that there was a significant difference in the achievement of total closure between those subjects who had a successful trial and those who did not. CONCLUSION: Combined modulated ultrasound and electric field stimulation has a place as adjunct therapy that aids wound healing and provides an effective noninvasive treatment option.
