Using Facebook Advertising to Recruit Representative Samples: Feasibility Assessment of a Cross-Sectional Survey

Posttraumatic Stress Symptoms among Obstetricians with Personal Experience of Birth Trauma

Psychological birth trauma (BT), defined as an event that occurs during labor and delivery involving actual or threatened harm or death to the pregnant person and/or their baby, has been reported in up to one-third of births. Obstetrician-Gynecologists (OBGYNs) who personally experience BT are at a unique risk of re-traumatization upon return to work. We aimed to investigate the prevalence of personal BT among obstetricians and their perceptions of how personal BT impacts their experience of caring for obstetric patients.We performed a web-based survey of OBGYNs who had given birth. Participants were recruited from the "OMG (OBGYN Mom Group)" on Facebook. The questionnaire assessed individuals' personal experience of childbirth using items adapted from the "City Birth Trauma Scale" to assess posttraumatic symptoms related to their childbirth and patient interactions following the personal experience of BT. Responses were categorized by whether or not the participant considered one or more of their own births to be traumatic. Posttraumatic stress symptoms (PTSSs) and symptoms of occupational re-traumatization were compared by reported BT. Bivariable analyses were used.Of the 591 OBGYNs who completed the survey, 180 (30.5%) reported experiencing BT. Ninety-two percent of OBs cared for birthing patients after giving birth. There were no differences in demographic or clinical practice characteristics between those with and without BT. OBGYNs with BT experienced PTSSs including flashbacks (60.6 vs. 14.4%), amnesia (36.7 vs. 20.9%), and insomnia (24.4 vs. 1.2%) at higher rates than those without BT (p < 0.001).Almost one-third of OBGYNs in this sample reported personally experiencing BT, mirroring data from reported BT rates in the general population. Given that OBGYNs are at high risk for occupational re-traumatization, initiatives focused on improving support for birthing OBGYNs upon returning to work should be studied to assess the impact on emotional wellness among practicing OBGYNs. · Birthing OBGYNs experience psychological BT at similar rates to the general population.. · OBGYNs who experience personal BT may experience PTSSs at work.. · Further research on the prevalence of personal BT among OBGYNs is needed..

User Perceptions of Behavioral Change Strategies in Diabetes Apps: Feedback From Online Support Groups

BACKGROUND

Behavioral change strategies are used in mobile health applications to help individuals manage chronic conditions like diabetes. However, there is limited research on user preferences and perceptions regarding these strategies in the context of diabetes management apps. This study aimed to investigate the preferences of individuals with diabetes and their relatives concerning behavioral intervention functions used in mobile health apps to enhance the design and effectiveness of future applications.

METHODS

An online survey was conducted to gather sociodemographic information, details about diabetes diagnoses, and the target group's preferences for the use of nine main behavioral change strategies, possible to include in mobile health apps. Participants were asked to rate their agreement with specific statements related to each of the nine strategies on a three-point scale: "Agree," "Don't know," or "Disagree." Recruitment efforts targeted 12 diabetes support groups on Facebook.

RESULTS

A total of 107 responses were received, all from Norwegian Facebook groups. The most valued behavior intervention function for diabetes apps was enablement, where 85% of the respondents wanted app functions based on this. Second, environmental restructuring received 70.1% votes, followed by incentivization and training, with 68.2% and 67.3%, respectively.

CONCLUSIONS

We identified that the users in this survey preferred more, and other behavior change strategies that were identified were used in a recent review. We conclude that more awareness is needed among app developers of preferences among end users.

A Comparative Analysis of Recruitment Methods to Reach Emerging Adults Outside the Clinical Setting

BACKGROUND

Emerging adults are a hard-to-recruit population for health researchers, as many do not routinely access healthcare services and are best recruited outside clinical settings. Social media and research volunteer registries (e.g., ResearchMatch) offer great potential among this population, yet a comparison of these two recruitment methods has not been done.

OBJECTIVES

The aim of this study was to compare participant enrollment and completion rates, participant demographics, and recruitment costs between recruitment methods (social media advertisements compared to ResearchMatch) deployed with a sample of emerging adults assigned female at birth.

METHODS

Participants were recruited from October to November 2022 via ResearchMatch and social media (Instagram and Snapchat) advertisements. This analysis involves a subset of recruitment data from a larger institutional review board-approved study. Enrollment and survey completion rates were calculated using the number of individuals contacted and survey completion data from Qualtrics. Chi-square and independent t -test analyses were used to compare demographic data. Advertisement data collected included total cost, cost per click, link clicks, and paid impressions.

RESULTS

Two hundred forty-five emerging adults completed the survey, and 24 completed follow-up interviews. ResearchMatch and social media enrollment rates differed (58% and 39%, respectively). Survey completion rates for both methods were the same (~93%). Participants' ages and levels of education were significantly different. Social media resulted in recruitment of younger participants (18-21 years old), and ResearchMatch garnered participants with a higher level of education. Differences in race were also significant, as social media recruited higher numbers of White participants. Lastly, the researcher-incurred cost per survey was $0 for ResearchMatch versus $13 for social media.

DISCUSSION

Although social media and ResearchMatch are both successful tools for research recruitment, each provides distinct benefits for recruiting specific populations. ResearchMatch offers a lower-cost option and access to an older emerging adult population with higher education, whereas social media provides access to a younger emerging adult population. This knowledge can be imperative for deciding which recruitment methods best fit research study needs. Future research should explore differences in race by recruitment method to highlight potential sampling biases or recruitment opportunities.

Age of tobacco, nicotine and cannabis use initiation in Switzerland: a sequence analysis among adolescents and young adults

BACKGROUND

To explore at what age youth start using tobacco and/or nicotine products, which product is used first, product initiation sequences, and whether some socio-demographic characteristics are associated with substance use initiation.

METHODS

Data were collected from an online questionnaire disseminated through social media and professional partners, targeting youth aged 14-25 in French-speaking Switzerland in August 2022. The final sample included 1362 participants. Respondents were asked whether they had already used cigarettes, e-cigarettes, hookah, snus, or cannabis at least once in their life (yes/no) and the age of the first time was asked for each substance when the answer was positive. Additionally, participants were asked about their substance use in the past 30 days. Respondents were classified according to age at onset of each tobacco/nicotine and cannabis product, and comparisons were made based on sociodemographic variables, including gender (cisgender female/cisgender male/transgender), perceived socioeconomic status (below average/average/above average), and age.

RESULTS

Overall, in addition to those who reported no consumption, four distinct initiation profiles emerged from the classification. Cigarettes remain the most commonly used first product with an average age of 15.7 years. While cigarettes and hookah are present in all profiles, the order of first consumption varies from one profile to another, with cigarettes coming first in two profiles, hookah in one and e-cigarettes in the last. Furthermore, while the most common profile contains experimental consumption of the five products considered, some profiles do not contain cannabis, e-cigarettes and/or snus, for example. When divided by age groups, both 14-17-year-olds and 18-21-year-olds reported cigarette as their first product of initiation. Across the separate age groups (14-17, 18-21, 22-25), cigarettes consistently emerge as the primary used on average.

CONCLUSIONS

Cigarettes remain the first product to be used, but the younger the respondents, the earlier they start using e-cigarettes, and very close to cigarettes. Regarding current consumption patterns, e-cigarettes are becoming increasingly prominent.

Using Social Media to Recruit Participants in Health Care Research: Case Study

This paper presents a case study describing the use of social media, specifically Facebook and Instagram, as a valuable tool for recruiting participants in community-engaged health care studies. Drawing on the experiences of our team during a qualitative study aiming to understand the needs of Indigenous fathers and Two-Spirit parents as they transition to parenthood, we offer an in-depth exploration of our social media recruitment strategy. This strategy encompasses deliberate content creation and online engagement with local Indigenous community organizations and people. Through the implementation of this recruitment strategy, we successfully recruited 18 Indigenous fathers and 4 Two-Spirit parents to our community-engaged project. We learned that social media can be used to enhance recruitment by building community trust, engagement, tailored content for specific audiences, and adaptive strategies guided by data metrics provided by social media platforms. Our journey included several challenges, such as dealing with fraudulent participants, navigating budget and resource constraints, and facing recruitment limitations, which we also describe in detail. Our paper provides essential insights for researchers considering the use of social media as a recruitment tool but we are unsure of how to begin. Health care researchers may find our experience and recommendations helpful for developing and implementing their own effective social media recruitment strategy. Meanwhile, sharing our experience contributes to the broader understanding of the role of social media in participant recruitment.

Vaping habits and respiratory symptoms using a smartphone app platform

BACKGROUND

Widespread use of e-cigarette (EC) or vaping products causes respiratory disorders including the nationwide outbreak of e-cigarette or vaping product use-associated lung injury (EVALI) in 2019. Chronic adverse health effects are now being reported as well. To address this important public health issue, an innovative approach of epidemic control and epidemiologic study is required. We aimed to assess the association between short-term and long-term use of EC products and respiratory health in adults using smartphone app data.

METHODS

A population-based, repeated measures, longitudinal smartphone app study that performed 8-day survey participation over 60 days for each participant from August 2020 to March 2021, including 306 participants aged 21 years and older in the US. The participants were asked to complete the respiratory health questionnaire daily, weekly, and monthly on their smartphone app. We analyzed the association between vaping habits and respiratory health using generalized linear mixed models (GLMMs).

RESULTS

EC use in the previous 7 days was associated with frequent cough (OR: 5.15, 95% CI: 2.18, 12.21), chronic cough (OR: 3.92, 95% CI: 1.62, 9.45), frequent phlegm (OR: 3.99, 95% CI: 1.44, 11.10), chronic phlegm (OR: 3.55, 95% CI: 1.41, 8.96), episodes of cough and phlegm (OR: 4.68, 95% CI: 1.94, 11.28), mMRC grade 3-4 dyspnea (OR: 3.32, 95% CI: 1.35 to 8.13), chest cold (OR: 3.07, 95% CI: 1.29, 7.33), eye irritation (OR: 2.94, 95% CI: 1.34, 6.47) and nose irritation (OR : 2.02, 95% CI: 0.95, 4.30). Relatively long-term effects of the past 90 days EC use was associated with an increased risk of wheeze (OR: 3.04, 95% CI: 1.31, 7.03), wheeze attack (OR: 2.78, 95% CI: 1.07, 7.24), mMRC grade 3-4 dyspnea (OR: 2.54, 9% CI: 1.05 to 6.18), eye irritation (OR: 3.16, 95% CI: 1.49, 6.68), and eye irritation during the past month (OR: 3.50, 95% CI: 1.52, 8.04).

CONCLUSIONS

In this smartphone app-based repeated measures study, short-term and relatively long-term use of EC increased the risk of respiratory symptoms.

Designing and implementing an experimental survey on knowledge and perceptions about alcohol warning labels

OBJECTIVES

This paper describes the design and implementation of an online survey experiment to investigate the effects of alcohol warning labels on alcohol-related knowledge, risk perceptions and intentions.

METHOD

The survey collected self-reported data from 14 European countries through two waves of data collection with different recruitment strategies: dissemination via social media and public health agencies was followed by paid-for Facebook ads. The latter strategy was adopted to achieve broader population representation. Post-stratification weighting was used to match the sample to population demographics.

RESULTS

The survey received over 34,000 visits and resulted in a sample size of 19,601 participants with complete data on key sociodemographic characteristics. The responses in the first wave were over-representing females and higher educated people, thus the dissemination was complemented by the paid-for Facebook ads targeting more diverse populations but had higher attrition rate.

CONCLUSION

Experiments can be integrated into general population surveys. Pan-European results can be achieved with limited resources and a combination of sampling methods to compensate for different biases, and statistical adjustments.

Prenatal and postpartum care during the COVID-19 pandemic: An increase in barriers from early to mid-pandemic in the United States

BACKGROUND

The COVID-19 pandemic led to changes in the provision of pregnancy and postpartum care. The purpose of this study was to describe changes in access to prenatal and postpartum care over time, from early in the pandemic (July 2020) to mid-pandemic (January 2021) and to explore socioeconomic and COVID-19-related economic factors associated with experiencing barriers to care.

METHODS

We recruited two cross sections of women and birthing people in the US in July 2020 (N = 4645) and January 2021 (N = 3343) using Facebook and Instagram Ads.

RESULTS

Three out of four women in the prenatal period and four out of five women in the postpartum period reported barriers to scheduling a visit. The likelihood of not having a visit (OR = 4.44, 95% CI 2.67-7.40), being unable to schedule a visit (OR = 2.73, 95% CI 1.71-4.35), and not being offered visits (OR = 4.26, 95% CI 2.32-7.81) increased over time. Participants were more likely to report barriers attending scheduled prenatal or postpartum appointments over time (OR = 2.72, 95% CI 2.14-3.45). Women who experienced more economic impacts from COVID-19 were older, less educated, and were Black, Indigenous, or a person of color, and were more likely to have barriers to attending appointments.

CONCLUSIONS

Certain subgroups are more at risk during COVID-19, and around 9 months into the pandemic, women were not only still facing barriers to care, but these had been amplified. Additional research using other data sources is needed to identify and ameliorate barriers and inequalities in access to prenatal and postpartum care that appear to have persisted throughout the pandemic.

What are the characteristics of disposable electronic cigarettes users in Switzerland? A quantitative study among 14-25 year olds

ABSTRACT

Introduction

Disposable electronic cigarettes (DEC) appeared in Switzerland in 2020. The aim of this study is to determine the prevalence of DEC use among youth (14-25 year olds) living in French-speaking Switzerland and their characteristics.

Methods

Data were obtained from a web-based survey conducted in August 2022. Participants were divided into four DEC user groups according to and were compared on sociodemographic data, substance use, family substance use and advertising viewing. Additional questions such as purchase methods and motivations were asked to the user groups.

Results

Among the 1362 participants, 41.2% had never used a DEC (NEVER), 14.4% once (ONCE), 15.1% several times but not in the last 30 days (PAST) and 29.2% several times in the last 30 days (CURRENT). At the multivariate level, compared with the NEVER group, participants in the CURRENT group were more likely to have used cigarettes and cannabis in the last 30 days, to report family electronic cigarettes use and to have seen online advertising for DEC. Among DEC users, compared with the ONCE group, those in the CURRENT group were less likely to be cisgender males, to have acquired their last DEC through peers or family and to use DEC out of curiosity.

Conclusions

Although most youth do not consume DEC regularly, these results raise concerns about growing exposure of young people to highly addictive products. They underline the importance of monitoring products availability, marketing and prevalence. They also confirm the necessity to inform the public, denormalise use and strengthen regulations.

Low-Cost Recruitment Approach: Utilizing Facebook Groups to Recruit COVID-19 Long-Haulers

Introduction

The accessibility of social media (e.g., Facebook groups) presents long-haulers with the ability to connect with others with similar experiences and symptomology that are likely outside of their physical social networks. Social media sites may serve as promising platforms for research recruitment, public health campaigns, or interventions. The present study aims to assess, and comprehensively present, the effectiveness of a low-cost approach to recruitment through groups on Facebook within the context of a broader study of COVID-19 long-haulers.

Methods

Facebook groups were searched using a variety of COVID-related terminology and included if they were in English, COVID-19 specific, public, and have or were approaching 1,000 or more members. Group administrators were either contacted for permission to post recruitment materials or posts were made and left pending administrator approval, depending on group settings. Group members were able to follow a link to the online survey platform (i.e., RedCap) where they provided informed consent and completed an online assessment of their COVID-19 experiences and psychosocial wellbeing. Upon survey completion participants were able to opt-in to a raffle-based incentive. The characteristics of the Facebook groups and demographic background of participants were assessed.

Findings

Contacting administrators and posts made between January and March of 2022 within 17 COVID-19 specific groups yielded a sample size of 460 long-haulers. The groups relied upon for recruitment had a mean size of 21,022 (SD=45,645.3), most had three or more administrators (43%), and a majority were state specific (60%). The long-hauler participants enrolled from the posts had an average age of 32 years (SD=6.19), approximately split between men (48.91%) and women (50.22%), a majority white (70%), having earned a bachelor's or postgraduate degree (63.48%), and reporting an annual income between $50,000 and $100,000 (56.09%).

Discussion

The present study presents strengths and recommendations for survey recruitment through Facebook groups as a low-cost recruitment strategy that is easily targeted to populations with a specific health condition and allows users to complete online psycho-behavioral assessments off-site on a HIPPA compliant survey platform.

Behavioral Insights from Vaccine Adoption in Nigeria: Cross-Sectional Survey Findings

BACKGROUND

To generate behavioral insights for the development of effective vaccination interventions, we need approaches that combine rapid and inexpensive survey data collection with instruments based on easy-to-use behavior models. This study demonstrates how an inexpensive digital survey helped identify the drivers of COVID-19 vaccination in Nigeria.

OBJECTIVE

This study aims to illustrate how behavioral insights can be generated through inexpensive digital surveys.

METHODS

We designed and conducted a cross-sectional survey with multistage sampling. Data were collected from Nigerians (aged ≥18 years) from 120 strata based on age, sex, state, and urban or rural location. Respondents were recruited via advertisements on Meta platforms (Facebook and Instagram) using the Virtual Lab open-source tool. We used a Meta Messenger chatbot for data collection; participants were compensated with 400 naira (US $0.87 cents). Data collection took 2 weeks. In total, 957 respondents completed the survey, at an advertising cost of US $1.55 per respondent. An 18-item instrument measuring core motivators, ability barriers, sociodemographic characteristics, and respondents' vaccination status was pretested before data collection. We ran separate logistic regression models to examine the relationships between vaccine uptake and core motivators, ability barriers, and sociodemographic variables. A final model that predicted vaccine uptake included all 3 sets of variables.

RESULTS

About 56% (n=540) of respondents reported that they had received at least 1 COVID-19 vaccination. Three core motivators were positively associated with vaccine uptake: the belief that the COVID-19 vaccine promised a better life (adjusted odds ratio [aOR] 3.51, 95% CI 2.23-5.52), the belief that the vaccine would allow respondents to do more things they enjoyed (aOR 1.97, 95% CI 1.33-2.93), and respondents' perception that their friends and family members accepted their decision to get vaccinated (aOR 1.62, 95% CI 1.06-2.48). Two ability barriers were negatively associated with vaccine uptake: cost- or income-related concerns lowered the odds of being vaccinated (aOR 0.35, 95% CI 0.24-0.50) and the lack of availability of vaccines at places respondents routinely visited also lowered their odds of being vaccinated (aOR 0.29, 95% CI 0.21-0.40). After adjusting for other variables, the perceived fear of getting COVID-19 and the hardship associated with the disease were no longer associated with vaccine uptake.

CONCLUSIONS

These findings suggest that hope is more important for Nigerians than fear when it comes to vaccine adoption, enjoying life is more important than worrying about getting the disease, and approval from friends and family is more powerful than their disapproval. These findings suggest that emphasizing the benefits of leading a fuller life after being vaccinated is more likely to succeed than increasing Nigerians' fear of COVID-19. This study identifies a very different set of factors associated with COVID-19 vaccine adoption than previous Nigerian studies.

Effectiveness and Cost of Using Facebook Recruitment to Elicit Canadian Women's Perspectives on Bone Health and Osteoporosis: Cross-Sectional Survey Study

BACKGROUND

Surveys can help health researchers better understand the public's perspectives and needs regarding prevalent conditions such as osteoporosis, which affects more than two-thirds of postmenopausal women. However, recruitment of large cohorts for survey research can be time-consuming and expensive. With 2.9 billion active users across the globe and reasonable advertising costs, Facebook (Meta Platforms, Inc) has emerged as an effective recruitment tool for surveys, although previous studies have targeted young populations (<50 years of age) and none have focused on bone health.

OBJECTIVE

We assessed the effectiveness and cost of using Facebook to recruit Canadian women aged ≥45 years to share their perspectives on bone health and osteoporosis via a web-based survey.

METHODS

We developed a 15-minute web-based survey with the goal of eliciting perspectives on bone health and osteoporosis. A Facebook advertisement was placed for 2 weeks in February 2022, during which time it was shown to women of age ≥45 years who resided in Canada, inviting them to participate and offering a chance to win 1 of 5 CAD $100 gift cards (at the time of this study [February 14, 2022], a currency exchange rate of CAD $1=US $0.79 was applicable). Those who clicked on the advertisement were taken to an eligibility screening question on the survey home screen. Individuals who confirmed eligibility were automatically directed to the first survey question. All individuals who answered the first survey question were considered participants and included in the analyses. We determined the survey reach, click rate, cooperation rate, completion rate, cost per click, and cost per participant. Sociodemographic characteristics of respondents were compared with data from the 2021 Canadian Census.

RESULTS

The Facebook advertisement was shown to 34,086 unique Facebook users, resulting in 2033 link clicks (click rate: 6.0%). A total of 1320 individuals completed the eligibility screening question, 1195 started the survey itself (cooperation rate: 58.8%), and 966 completed the survey (completion rate: 47.5%). The cost of the advertising campaign was CAD $280.12, resulting in a cost per click of CAD $0.14 and a cost per participant of CAD $0.23. The 1195 participants ranged in age from 45-89 years (mean 65, SD 7 years), 921 (93.7%) were of White ethnicity, 854 (88.3%) had completed some postsecondary education, and 637 (65.8%) resided in urban areas. Responses were received from residents of all 10 Canadian provinces and 2 of 3 territories. When compared to 2021 Canadian Census data, postsecondary education and rural residence were overrepresented in our study population.

CONCLUSIONS

Facebook advertising is an efficient, effective, and inexpensive way of recruiting large samples of older women for participation in web-based surveys for health research. However, it is important to recognize that this modality is a form of convenience sampling and the benefits of Facebook recruitment must be balanced with its limitations, which include selection bias and coverage error.

Contraceptive care in the United States during the COVID-19 pandemic: A social media survey of contraceptive access, telehealth use and telehealth quality

OBJECTIVES

To examine demographic, socioeconomic, and regional differences in contraceptive access, differences between telehealth and in-person contraception visits, and telehealth quality in the United States during the COVID-19 pandemic.

STUDY DESIGN

We surveyed reproductive-age women about contraception visits during the COVID-19 pandemic via social media in July 2020 and January 2021. We used multivariable regression to examine relationships between age, racial/ethnic identity, educational attainment, income, insurance type, region, and COVID-19 related hardship, and ability to obtain a contraceptive appointment, telehealth vs in-person visits, and telehealth quality scores.

RESULTS

Among 2031 respondents seeking a contraception visit, 1490 (73.4%) reported any visit, of which 530 (35.6%) were telehealth. In adjusted analyses, lower odds of any visit was associated with Hispanic/Latinx and Mixed race/Other identity (aOR 0.59 [0.37-0.94], aOR 0.36 [0.22-0.59], respectively), the South, Midwest, Northeast (aOR 0.63 [0.47-0.85], aOR 0.64 [0.46-0.90], aOR 0.52 [CI 0.36-0.75], respectively), no insurance (aOR 0.63 [0.43-0.91]), greater COVID-19 hardship (aOR 0.52 [0.31-0.87]), and earlier pandemic timing (January 2021 vs July 2020 aOR 2.14 [1.69-2.70]). Respondents from the Midwest and South had lower odds of telehealth vs in-person care (aOR 0.63 [0.44-0.88], aOR 0.54 [0.40-0.72], respectively). Hispanic/Latinx respondents and those in the Midwest had lower odds of high telehealth quality (aOR 0.37 [0.17-0.80], aOR 0.58 [0.35-0.95], respectively).

CONCLUSIONS

We found inequities in contraceptive care access, less telehealth use for contraception visits in the South and Midwest, and lower telehealth quality among Hispanic/Latinx people during the COVID-19 pandemic. Future research should focus on telehealth access, quality, and patients' preferences.

IMPLICATIONS

Historically marginalized groups have faced disproportionate barriers to contraceptive care, and telehealth for contraceptive care has not been employed equitably during the COVID-19 pandemic. Though telehealth has the potential to improve access to care, inequitable implementation could exacerbate existing disparities.

AI model GPT-3 (dis)informs us better than humans

Artificial intelligence (AI) is changing the way we create and evaluate information, and this is happening during an infodemic, which has been having marked effects on global health. Here, we evaluate whether recruited individuals can distinguish disinformation from accurate information, structured in the form of tweets, and determine whether a tweet is organic or synthetic, i.e., whether it has been written by a Twitter user or by the AI model GPT-3. The results of our preregistered study, including 697 participants, show that GPT-3 is a double-edge sword: In comparison with humans, it can produce accurate information that is easier to understand, but it can also produce more compelling disinformation. We also show that humans cannot distinguish between tweets generated by GPT-3 and written by real Twitter users. Starting from our results, we reflect on the dangers of AI for disinformation and on how information campaigns can be improved to benefit global health.

The Effects of Cancer Beliefs and Sociodemographic Factors on Colorectal Cancer Screening Behaviours in Newfoundland and Labrador

Objectives: This study investigated the beliefs about cancer treatment, outcomes, and screening among adults aged 50−74 in Newfoundland and Labrador and whether these beliefs or sociodemographic factors were associated with differences in colorectal cancer (CRC) screening behaviours. Methods: This analysis uses data collected from an online survey of adults on cancer awareness and prevention in NL. Chi-square tests were used to assess differences in distributions of beliefs based on CRC screening behaviour. Logistic regression was used to identify sociodemographic factors independently associated with CRC screening behaviour. Results: A total of 724 participants were included in the analysis, 57.4% of which had ever had CRC screening. Most held positive beliefs about cancer outcomes and treatment. Only beliefs about screening affected CRC screening behaviour. People who never had CRC screening were more likely to believe their worries about what might be found would prevent them from screening (χ2 = 9.380, p = 0.009); screening is only necessary if they have symptoms (χ2 = 15.680, p < 0.001); and screening has a high risk of leading to unnecessary surgery (χ2 = 6.824, p = 0.032). Regression identified that men had higher likelihood of having had CRC screening than women in our study (OR = 1.689, 95%CI = 1.135−2.515), as did all age groups compared to ages 50−54. No associations were found with the other sociodemographic factors studied. Conclusion: Beliefs about cancer screening appear to play some role in CRC screening behaviour, but the absolute effect was small. The relatively few sociodemographic associations with screening behaviour suggest that NL’s CRC screening program is equitably reaching people from different socioeconomic backgrounds.

Using Social Media to Collect Dietary Information for Public Health Policy

There is no regular, routine measurement of food and nutrient intake regionally in the UK. Our goal was to identify a method to support policy makers tracking the local population food intakes. The aim of this study was to test the feasibility of using social media to obtain a large sample in a short time, with a regional focus; collecting dietary information using online tools. A Facebook (FB) boost approach was used to recruit a regional (Yorkshire and Humberside) sample of adults to complete a brief online survey followed by a detailed measure of food and nutrient intakes for the previous day using myfood24®. The FB posts were boosted for 21 days and reached 76.9 k individuals. 1428 participants completed the main questionnaire and 673 participants completed the diet diary. The majority of respondents were older women. 22% of respondents reported experiencing moderate food insecurity during 2021. Overall nutrient values recorded were similar to national survey data. Intakes of fibre and iron were low. Despite some challenges, this study has demonstrated the potential to use social media, in this case Facebook, to recruit a large sample in a short timeframe. Participants were able to use online tools to report food and nutrient intakes. This data is relevant to local and national policy makers to monitor and evaluate public health programmes.

Using mobile phone-based text message to recruit representative samples: Assessment of a cross-sectional survey about the COVID-19 vaccine hesitation

BACKGROUND

Limited research has examined mobile phone-based platforms for survey recruitment, especially during the COVID-19 pandemic in Brazil. Our objective was to investigate the feasibility and representativeness of mobile phone-based advertisement during a preliminary study about COVID-19 vaccine hesitation in Brazil. Moreover, we evaluate whether the older population can be reached through mobile phone-based platforms of the survey.

METHODS

We conducted a study in December 2021 based on a preliminary survey about the COVID-19 vaccine hesitation in Assis, Brazil, Sao Paulo state. From a list of the adult population hesitant about the second dose of the COVID-19 vaccine, we sent a mobile phone-based advertisement inviting the participants to answer the survey for one week. The respondent's data were collected in a Google form platform. The comparison between the target population and the respondents was made using the Chi-squared test and the Welch's test, using a P-value of 0.05 as significative.

RESULTS

The response rate was 9.99% after one week. The mean age of the respondent group was 33.97 (SD 14.99) and 35.05 (SD 14.19) of the population, with a P-value of 0.192 and a Cohen's d coefficient of 0.0754, corresponding to a small effect size between groups. We demonstrate that the mobile phone-based survey is a feasible and representative strategy during the pandemics in Brazil. Moreover, the older population respondent was representative.

CONCLUSION

We achieved a representative sample of respondents using the mobile phone-based survey in Brazil. Furthermore, it was representative of all sociodemographic and health characteristics assessed. Finally, these findings suggest that the method is a highly feasible and economical means of recruiting for survey research.

Social Media Use for Research Participant Recruitment: Integrative Literature Review

BACKGROUND

Social media tools have provided health researchers with the opportunity to engage with communities and groups in a nonconventional manner to recruit participants for health research. Using social media to advertise research opportunities and recruit participants facilitates accessibility to participants from broad geographical areas and diverse populations. However, little guidance is provided by ethics review boards for researchers to effectively use this recruitment method in their research.

OBJECTIVE

This study sought to explore the literature on the use of social media for participant recruitment for research studies and identify the best practices for recruiting participants using this method.

METHODS

An integrative review approach was used to synthesize the literature. A total of 5 health sciences databases, namely, EMBASE (Ovid), MEDLINE (Ovid and EBSCOhost), PsycINFO (Ovid), Scopus (Elsevier), and CINAHL Plus with Full Text (EBSCOhost), were searched using predefined keywords and inclusion and exclusion criteria. The initial search was conducted in October 2020 and was updated in February 2022. Descriptive and content analyses were applied to synthesize the results, and the findings are presented in a narrative and tabular format.

RESULTS

A total of 96 records were included in this review, 83 (86%) from the initial search and 13 (14%) from the updated search. The publication year ranged between 2011 and 2022, with most publications (63/96, 66%) being from the United States. Regarding recruitment strategy, 45% (43/96) of the studies exclusively used social media, whereas 51% (49/96) used social media in conjunction with other strategies. The remaining 4% (4/96) provided guidelines and recommendations for social media recruitment. Notably, 38% (36/96) of these studies involved hard-to-reach populations. The findings also revealed that the use of social media is a cost-effective and efficient strategy for recruiting research participants. Despite the expanded use across different populations, there is limited participation of older adults in social media recruitment.

CONCLUSIONS

This review provides important insights into the current use of social media for health research participant recruitment. Ethics boards and research support services in academic institutions are encouraged to explicitly provide researchers with guidelines on the use of social media for health research participant recruitment. A preliminary guideline prepared based on the findings of this review is proposed to spark further development in this area.

The Importance of Behavioral and Native Factors on COVID-19 Infection and Severity: Insights from a Preliminary Cross-Sectional Study

The COVID-19 pandemic has had a major impact on a global scale. Understanding the innate and lifestyle-related factors influencing the rate and severity of COVID-19 is important for making evidence-based recommendations. This cross-sectional study aims at establishing a potential relationship between human characteristics and vulnerability/resistance to SARS-CoV-2. We hypothesize that the impact of the virus is not the same due to cultural and ethnic differences. A cross-sectional study was performed using an online questionnaire. The methodology included the development of a multi-language survey, expert evaluation, and data analysis. Data were collected using a 13-item pre-tested questionnaire based on a literature review between 9 December 2020 and 21 July 2021. Data were statistically analyzed using logistic regression. For a total of 1125 respondents, 332 (29.5%) were COVID-19 positive; among them, 130 (11.5%) required home-based treatment, and 14 (1.2%) intensive care. The significant and most influential factors on infection included age, physical activity, and health status (p < 0.05), i.e., better physical activity and better health status significantly reduced the possibility of infection, while older age significantly increased it. The severity of infection was negatively associated with the acceptance (adherence and respect) of preventive measures and positively associated with tobacco (p < 0.05), i.e., smoking regularly significantly increases the severity of COVID-19 infection. This suggests the importance of behavioral factors compared to innate ones. Apparently, individual behavior is mainly responsible for the spread of the virus. Therefore, adopting a healthy lifestyle and scrupulously observing preventive measures, including vaccination, would greatly limit the probability of infection and prevent the development of severe COVID-19.

Piling it on: Perceived stress and lack of access to resources among US-based LGBTQ+ community members during the COVID-19 pandemic

OBJECTIVES

While the LGBTQ+ community has been disproportionally impacted by COVID-19 medical complications, little research has considered non-medical impact.

METHODS

We conducted a secondary analyses of USA-based respondents from a global cross-sectional online mixed-methods survey collecting sexual orientation, gender identity, and the perceived stress scale (PSS). Bivariate and multivariate ordinal regression statistics were performed.

RESULTS

Fourteen percent (n = 193,14.2%) identified as LGBTQ+. Variables significantly associated with LGBTQ+ included: COVID testing/treatment affordability, canceled activities, stocking food/medications, quitting job, lost income, and inability to procure groceries/cleaning supplies/medications. Adjusting for Hispanic ethnicity and income, BIPOC LGBTQ+ individuals had twice the odds (OR:2.02;95%CI:1.16-3.53) of moderate compared to low PSS scores, and high compared to moderate PSS scores, compared to white non-LGBTQ+ individuals. Adjusting for Hispanic ethnicity, income, age, and education, deaf LGBTQ+ individuals had twice the odds (OR:2.00;95%CI:1.12-3.61) of moderate compared to low PSS scores, and high compared to moderate PSS scores, compared to hearing non-LGBTQ+ individuals.

CONCLUSION

The LBGTQ+ community has increased stress due to COVID-19. Public health interventions must mitigate stress in BIPOC and deaf LGBTQ+ communities, addressing their intersectional experiences.

The Relationship Among Mentalization, Mindfulness, Working Memory, and Schizotypal Personality Traits in the General Population

Individuals with high schizotypal traits are less able to observe, describe, and monitor inner feelings, thoughts, and experiences, commonly referred to as mindfulness and mentalization. High schizotypy is also associated with impaired working memory (WM). However, the relationship among mindfulness, mentalization, WM, and schizotypal traits is unknown. Three hundred individuals from the community (mean age: 38.0 years, SD = 10.5; 49.3% women) completed questionnaires examining schizotypal traits, mindfulness, and mentalization and performed working memory tasks. Results revealed that mentalization was a general predictor of schizotypal traits, including unusual experiences, cognitive disorganization, introverted anhedonia, and impulsive nonconformity, when the effect of mindfulness and working memory was controlled. We also found a positive correlation between mindfulness and mentalization. Low mindfulness and mentalization performances were associated with high schizotypy. However, poor working memory was only weakly linked to cognitive disorganization and introverted anhedonia. These findings suggest that weak mentalization is a core feature of schizotypy independent of mindfulness and working memory.

"Strong Together": Minority Stress, Internalized Homophobia, Relationship Satisfaction, and Depressive Symptoms among Taiwanese Young Gay Men

Taiwan's legalization of same-sex marriage affords legal status for romantic relationships between sexual minority individuals. Yet, little is known about the role of intimate relationships in the experiences of minority stress and mental health among gay men. This study tested a model where internalized homophobia mediated the association between distal minority stress and depressive symptoms and relationship satisfaction was posited as a moderator. Data came from a sample (n = 557) of Taiwanese young gay men who were in a romantic relationship. Respondents completed the scales of distal minority stress, internalized homophobia, relationship satisfaction, and depressive symptoms. Mediation and moderation analyses were performed on the macro PROCESS. The Johnson-Neyman (J-N) technique was used to interpret the moderating effect of relationship satisfaction. Results show that both distal minority stress and internalized homophobia were positively associated with depressive symptoms. Internalized homophobia partially mediated the association between distal minority stress and depressive symptoms. Relationship satisfaction had a moderating effect. The effect of distal minority stress was lower among those who reported high satisfaction in their current romantic relationship. This study suggested that a satisfying relationship provides protection for gay men's mental health. Clinicians should attend to relationship issues when working with sexual minority clients.

Sexual Minority Stress, Adverse Childhood Experiences, and Obesity Among Gay Men in Taiwan: Findings from a Panel Study

Purpose: Obesity is linked to personal behaviors and external stressors. Despite emerging evidence that sexual minority stress (SMS) and adverse childhood experiences (ACEs) are associated with the risk of obesity, little is known about their independent and interactive effects on sexual minority men. This study investigated these relationships using panel data. Methods: Self-identified gay and bisexual adult men in Taiwan were recruited through Facebook advertisements to complete an online questionnaire. This study reports only on data from the gay subsample (n = 731, mean age = 28.05 years, standard deviation = 5.75 years) as the bisexual subsample (n = 132) was insufficient for comparative statistical analysis. Over two time points, respondents reported their body weight and height, experiences with SMS, and ACEs on an online survey platform. Data analysis was conducted using multiple logistic regression to determine the individual and interactive effects of the ACE score, ACE components, and SMS on the odds for obesity. Results: Almost 16% of the respondents met the criterion for obesity (body-mass index ≥27). In the adjusted models, neither SMS nor ACEs had significant associations with the likelihood of obesity. Only the interaction term of SMS and childhood sexual abuse was significant, indicating that victims of sexual abuse have an increased likelihood of obesity that SMS may intensify. Conclusions: This study shows that gay men who experience childhood sexual abuse and SMS accumulatively faced an increased risk of obesity. Healthy weight promotion for these men should address these stressors.

Facebook recruitment for research of children and parents during the COVID-19 pandemic

The COVID-19 pandemic has created unique challenges for recruitment of adults and children into clinical research. The sudden onset of stay-at-home orders and social distancing enacted in much of the United States created sudden barriers for researchers to recruit participants in-person. Recognizing the critical need to understand the impact of COVID-19 on children and families in real time, studies required an alternative approach. The present study sought to develop methods and establish the feasibility of utilizing Facebook's targeted advertising to enroll schoolaged children and their parents for a study examining the impact of the COVID-19 pandemic on families.

This study used an 8 week pay-per-click advertisement approach via Facebook for research recruitment. Parents of children age 8 to 17 were invited and asked to include their child. Standardized measures were included for parents and children. Zip code targeting was used to increase diversity in participants.

The ad campaign reached 213,120, yielding 3563 clicks, 684 parent participants, 494 child participants and a 26% conversion rate over eight weeks. The cost-per-click was $0.64, and cost-per-participant was $3.30 and $4.60 for parents and children, respectively.

This nationwide study successfully used social media to recruit a robust nationwide sample of parent-child dyads during the COVID-19 pandemic. Social media recruitment mitigated typical time and engagement barriers for participants while also circumventing social and physical distancing orders due to the pandemic which allowed for real time assessment of the pandemic's effects on families. Future consideration should be given.to social media as a research recruitment methodology.

Public perceptions of psychiatric, justice-involved, and elderly populations during the COVID-19 pandemic

The novel coronavirus disease (COVID-19) has had a significant global impact, with all countries facing the challenge of mitigating its spread. An unprecedented shortage of medical resources has raised concerns regarding allocation and prioritization of supplies, which may exacerbate social discrepancies for already vulnerable populations. As public opinion can impact healthcare policies, we aimed to characterize perceptions of psychiatric, forensic psychiatry, correctional, and elderly populations regarding COVID-19-related issues. This web-based study recruited participants (n = 583) from the general population in North America. The survey included perceptions of the pandemic, hypothetical scenarios on resource prioritization, and Likert scale questions. The majority of participants were cisgender female (72.7%), aged 31-74 years (80.0%), married (48.0%), retired (52.7%), resided in Canada (73.9%), had a college/university degree (50.9%) and had never worked in healthcare (66.21%). Most respondents reported not having a criminal history (95.88%), or a psychiatric disorder (78.73%). Perceptions of vulnerable populations were significantly different for resource allocation and prioritization (e.g., ventilator and vaccine resources, all p < 0.001). Healthcare workers and the elderly were commonly ranked the highest priority for resources, while forensic psychiatry and correctional populations were given the lowest priority. A high rate of disagreement was found for the more stigmatizing questions in the survey (all p < 0.0001). Our results suggest that perception from members of the general public in North America is aligned with current practices for resource allocation. However, individuals that already face social and health disparities may face additional opposition in decision-making for COVID-19 resources.

Knowledge barriers in a national symptomatic-COVID-19 testing programme

Symptomatic testing programmes are crucial to the COVID-19 pandemic response. We sought to examine United Kingdom (UK) testing rates amongst individuals with test-qualifying symptoms, and factors associated with not testing. We analysed a cohort of untested symptomatic app users (N = 1,237), nested in the Zoe COVID Symptom Study (Zoe, N = 4,394,948); and symptomatic respondents who wanted, but did not have a test (N = 1,956), drawn from a University of Maryland survey administered to Facebook users (The Global COVID-19 Trends and Impact Survey [CTIS], N = 775,746). The proportion tested among individuals with incident test-qualifying symptoms rose from ~20% to ~75% from April to December 2020 in Zoe. Testing was lower with one vs more symptoms (72.9% vs 84.6% p<0.001), or short vs long symptom duration (69.9% vs 85.4% p<0.001). 40.4% of survey respondents did not identify all three test-qualifying symptoms. Symptom identification decreased for every decade older (OR = 0.908 [95% CI 0.883-0.933]). Amongst symptomatic UMD-CTIS respondents who wanted but did not have a test, not knowing where to go was the most cited factor (32.4%); this increased for each decade older (OR = 1.207 [1.129-1.292]) and for every 4-years fewer in education (OR = 0.685 [0.599-0.783]). Despite current UK messaging on COVID-19 testing, there is a knowledge gap about when and where to test, and this may be contributing to the ~25% testing gap. Risk factors, including older age and less education, highlight potential opportunities to tailor public health messages. The testing gap may be ever larger in countries that do not have extensive, free testing, as the UK does.

Factors associated with COVID-19 vaccination intentions among adults in the deep South

The recent approval of several COVID-19 vaccines signals progress toward controlling the pandemic. Although social distancing and masking have been effective, vaccines are an important additional measure of protection to reduce COVID-19 spread. Adequate uptake is essential to reach herd immunity, estimated to be approximately 67%. However, vaccine hesitancy, the fast-tracked nature of the COVID-19 vaccines, and misinformation circulating through various forms of media have contributed to lower vaccination intention than desired. The current research study developed an online survey conducted via Facebook to explore the attitudes and perceptions of adult Alabama residents about COVID-19 and the COVID-19 vaccines. Of the 3,781 respondents, only 44.3% reported intent to receive a vaccine, with a large proportion reporting they were unsure (28.1%). Lack of intention to vaccinate was associated with low educational attainment, low COVID-19 knowledge levels, low income, and African American race. The current survey also explored participants’ influenza vaccine behavior as this information can also be used to inform successful COVID-19 vaccine distribution. Of the respondents, 56% report receiving the yearly influenza vaccine and the majority receive it at a pharmacy or healthcare provider office. This informs likely successful locations for COVID-19 vaccine distribution. Appropriate education targeted to populations most likely to refuse COVID-19 vaccination is essential to promote uptake. The information collected from the current study should be utilized to inform effective and efficient vaccine distribution strategies.

Diversifying Recruitment Registries: Considering Neighborhood Health Metrics

BACKGROUND

Disparities in clinical research participation perpetuate broader health disparities. Recruitment registries are novel tools to address known challenges in accrual to clinical research. Registries may accelerate accrual, but the utility of these tools to improve generalizability is unclear.

OBJECTIVE

To examine the diversity of a local on-line recruitment registry using the Area Deprivation Index (ADI), a publicly available metric of neighborhood disadvantage.

DESIGN

Retrospective analysis.

SETTING

Data were collected in the University of California Irvine Consent-to-Contact Registry.

PARTICIPANTS

We categorized N=2,837 registry participants based on the ADI decile (collapsed into quintiles) using a state-based rankings.

MEASUREMENTS

We examined the proportion of enrollees per ADI quintile and quantified the demographics of these groups. We assessed willingness to participate in studies involving unique research procedures among the ADI groups.

RESULTS

Although registry enrollees represented the full spectrum of the ADI, they disproportionately represented less disadvantaged neighborhoods (lowest to highest quintiles: 42%, 30%, 15%, 6%, 7%). Compared to participants from less disadvantaged neighborhoods, participants from more disadvantaged neighborhoods were more often female, of non-white race, and Hispanic ethnicity. Despite demographic differences, ADI groups were observed to have similar willingness to participate in research studies.

CONCLUSIONS

People from more disadvantaged neighborhoods may be underrepresented in recruitment registries, increasing the risk that they will be underrepresented when using these tools to facilitate prospective recruitment to clinical research. Once enrolled in registries, participants from more disadvantaged neighborhoods may be equally willing to participate in research. Efforts to increase representation of participants from disadvantaged neighborhoods in registries could be an important first step toward increasing the generalizability of clinical research.

Artificial Intelligence in Medicine: A Multinational Multi-Center Survey on the Medical and Dental Students' Perception

Background: The emerging field of artificial intelligence (AI) will probably affect the practice for the next generation of doctors. However, the students' views on AI have not been largely investigated. Methods: An anonymous electronic survey on AI was designed for medical and dental students to explore: (1) sources of information about AI, (2) AI applications and concerns, (3) AI status as a topic in medicine, and (4) students' feelings and attitudes. The questionnaire was advertised on social media platforms in 2020. Security measures were employed to prevent fraudulent responses. Mann-Whitney U-test was employed for all comparisons. A sensitivity analysis was also performed by binarizing responses to express disagreement and agreement using the Chi-squared test. Results: Three thousand one hundred thirty-three respondents from 63 countries from all continents were included. Most respondents reported having at least a moderate understanding of the technologies underpinning AI and of their current application, with higher agreement associated with being male (p < 0.0001), tech-savvy (p < 0.0001), pre-clinical student (p < 0.006), and from a developed country (p < 0.04). Students perceive AI as a partner rather than a competitor (72.2%) with a higher agreement for medical students (p = 0.002). The belief that AI will revolutionize medicine and dentistry (83.9%) with greater agreement for students from a developed country (p = 0.0004) was noted. Most students agree that the AI developments will make medicine and dentistry more exciting (69.9%), that AI shall be part of the medical training (85.6%) and they are eager to incorporate AI in their future practice (99%). Conclusion: Currently, AI is a hot topic in medicine and dentistry. Students have a basic understanding of AI principles, a positive attitude toward AI and would like to have it incorporated into their training.

COVID-19's impact on contraception experiences: Exacerbation of structural inequities in women's health

INTRODUCTION

Structural inequities may impact the relationship between COVID-19 and access to contraception.

METHODS

In July 2020 and January 2021, we used social media to survey 2 samples of women of reproductive age who had not been surgically sterilized and were not currently pregnant about their experiences seeking contraception. We explore whether experiences differed for people experiencing social and/or economic disadvantage due to COVID-19, using multivariable logistic regression to control for age, education and income.

RESULTS

In July 2020, 51.5% of respondents who sought contraception (total N = 3064) reported barriers to care compared to 55.3% in January 2021 (total N = 2276). A larger percent (14% in July 2020 and 22% in Jan 2021) reported not using their preferred method of contraception due to COVID-19. Individuals experiencing income loss (OR = 1.61, 95% CI 1.27-2.04 early in the COVID-19 pandemic and OR = 1.58, 1.21-2.06 mid COVID-19 pandemic) and hunger (OR = 1.73, 1.24-2.40 early and OR = 2.02, 1.55-2.64 mid-COVID-19 pandemic) were more likely to report they would be using a different method if not for COVID-19, compared to respondents without income loss or hunger.

CONCLUSIONS

COVID-19 has complicated access to contraception, especially for disadvantaged populations.

IMPLICATIONS

Efforts are needed to ensure access to contraception despite the COVID-19 epidemic, especially for disadvantaged populations.

Evaluating a Strengths-Based mHealth Tool (MyStrengths): Explorative Feasibility Trial

BACKGROUND

As the number of people living with chronic illnesses increases, providing wide-reaching and easy-to-use support tools is becoming increasingly important. Supporting people in this group to recognize and use more of their personal strengths has the potential to improve their quality of life. With this in mind, we have developed the MyStrengths app prototype, a gamefully designed app aimed at aiding users in both identifying their strengths and using these strengths more actively in their daily life.

OBJECTIVE

The goal of this study was to evaluate the user-reported feasibility and usefulness of the MyStrengths app. The study additionally aimed to explore whether the use of MyStrengths could be associated with selected psychosocial outcomes.

METHODS

A 31-day explorative feasibility trial with a pretest-posttest design and an optional end of study interview was conducted. Data collection included system-use log data, demographic information, pre- and post-psychosocial measures (ie, strengths use, self-efficacy, health-related quality of life, depression), user experience measures (ie, usability, engagement, flow), and interview data.

RESULTS

In total, 34 people with at least 1 chronic condition were enrolled in the study, with 26 participants (mean age 48 years, range 29-62 years; 1 male) completing the trial. Among these individuals, 18 were also interviewed posttrial. Participants used the MyStrengths app an average of 6 days during the trial period, with 54% (14/26) using the app over a period of at least 19 days. In total, 8738 unique app actions were registered. Of the psychosocial outcome measures, only 1 subscale, general health in the RAND 36-Item Health Survey, yielded significant pre- and posttest changes. Posttrial interviews showed that the number of participants who considered the MyStrengths app to be useful, somewhat useful, or not useful was evenly distributed across 3 groups. However, every participant did voice support for the strengths approach. All participants were able to identify a multitude of personal strengths using the MyStrengths app. Most participants that reported it to be useful had little or no previous experience with the personal strengths approach. A multitude of users welcomed the gameful design choices, particularly the rolling die feature, suggesting strengths exercises, activities that use a specific strength, were well received.

CONCLUSIONS

Although the reported usefulness and feedback from use varied, most participants were favorable to the strengths-focused approach to care and support. Consequently, low-threshold and wide-reaching mobile health tools that use a strengths-focused approach, such as MyStrengths, hold the potential to support people living with chronic illness in performing self-management and achieving mastery of their life.

Recruiting custodial grandmothers using Facebook

OBJECTIVES

Recruitment through Facebook is gaining favor as an approach for research, including clinical trials, because of the platform's ability to reach broad and diverse populations. As older adults increase their social media use, recruitment through Facebook has become a viable option. The purposes of this paper are to report the methodological process and lessons learned from recruiting custodial grandmothers (CGMs) for a cross-sectional study examining parenting self-efficacy and psychological well-being.

PARTICIPANTS

A total of 113 people consented and accessed the survey online, with 40 (35.4%) completing surveys. The final sample comprised 68 grandmothers, with 59% recruited via Facebook.

METHODS

Facebook recruitment for the online survey included creating a dedicated Facebook study page, accessing existing Facebook pages for custodial grandparents, and using paid advertising. Face-to-face recruitment strategies also were used with paper surveys.

RESULTS

We compared the characteristics of those completing online surveys versus paper surveys. CGMs completing the survey online were significantly younger and more likely to be Caucasian than those completing the paper survey.

CONCLUSIONS

Findings indicated online recruitment via Facebook is an advantageous method to reach CGMs. However, additional research is needed to determine if other online and social media platforms would be useful in recruiting this population.

Anosmia, ageusia, and other COVID-19-like symptoms in association with a positive SARS-CoV-2 test, across six national digital surveillance platforms: an observational study

BACKGROUND

Multiple voluntary surveillance platforms were developed across the world in response to the COVID-19 pandemic, providing a real-time understanding of population-based COVID-19 epidemiology. During this time, testing criteria broadened and health-care policies matured. We aimed to test whether there were consistent associations of symptoms with SARS-CoV-2 test status across three surveillance platforms in three countries (two platforms per country), during periods of testing and policy changes.

METHODS

For this observational study, we used data of observations from three volunteer COVID-19 digital surveillance platforms (Carnegie Mellon University and University of Maryland Facebook COVID-19 Symptom Survey, ZOE COVID Symptom Study app, and the Corona Israel study) targeting communities in three countries (Israel, the UK, and the USA; two platforms per country). The study population included adult respondents (age 18-100 years at baseline) who were not health-care workers. We did logistic regression of self-reported symptoms on self-reported SARS-CoV-2 test status (positive or negative), adjusted for age and sex, in each of the study cohorts. We compared odds ratios (ORs) across platforms and countries, and we did meta-analyses assuming a random effects model. We also evaluated testing policy changes, COVID-19 incidence, and time scales of duration of symptoms and symptom-to-test time.

FINDINGS

Between April 1 and July 31, 2020, 514 459 tests from over 10 million respondents were recorded in the six surveillance platform datasets. Anosmia-ageusia was the strongest, most consistent symptom associated with a positive COVID-19 test (robust aggregated rank one, meta-analysed random effects OR 16·96, 95% CI 13·13-21·92). Fever (rank two, 6·45, 4·25-9·81), shortness of breath (rank three, 4·69, 3·14-7·01), and cough (rank four, 4·29, 3·13-5·88) were also highly associated with test positivity. The association of symptoms with test status varied by duration of illness, timing of the test, and broader test criteria, as well as over time, by country, and by platform.

INTERPRETATION

The strong association of anosmia-ageusia with self-reported positive SARS-CoV-2 test was consistently observed, supporting its validity as a reliable COVID-19 signal, regardless of the participatory surveillance platform, country, phase of illness, or testing policy. These findings show that associations between COVID-19 symptoms and test positivity ranked similarly in a wide range of scenarios. Anosmia, fever, and respiratory symptoms consistently had the strongest effect estimates and were the most appropriate empirical signals for symptom-based public health surveillance in areas with insufficient testing or benchmarking capacity. Collaborative syndromic surveillance could enhance real-time epidemiological investigations and public health utility globally.

Social Media as a Platform for Recruitment to a National Survey During the COVID-19 Pandemic: Feasibility and Cost Analysis

Background

With improved accessibility to social media globally, health researchers are capitalizing on social media platforms to recruit participants for research studies. This has particularly been the case during the COVID-19 pandemic, when researchers were not able to use traditional methods of recruitment. Nevertheless, there is limited evidence on the feasibility of social media for recruiting a national sample.

Objective

This paper describes the use of social media as a tool for recruiting a national sample of adults to a web-based survey during the COVID-19 pandemic.

Methods

Between August and October 2020, participants were recruited through Facebook via two advertisement campaigns (paid option and no-cost option) into a web-based survey exploring the relationship between social determinants of health and well-being of adults during the COVID-19 pandemic. Data were analyzed using SPSS software and Facebook metrics that were autogenerated by Facebook Ads Manager. Poststratification weights were calculated to match the Australian population on the basis of gender, age, and state or territory based on the 2016 Australian census data.

Results

In total, 9594 people were reached nationally with the paid option and potentially 902,000 people were reached through the no-cost option, resulting in a total of 1211 survey responses. The total cost of the advertisement campaign was Aus $649.66 (US $489.23), resulting in an overall cost per click of Aus $0.25 (US $0.19).

Conclusions

Facebook is a feasible and cost-effective method of recruiting participants for a web-based survey, enabling recruitment of population groups that are considered hard to reach or marginalized. Recruitment through Facebook facilitated diversity, with participants varying in socioeconomic status, geographical location, educational attainment, and age.

Identifying Aspects of Public Attitudes Toward Whole Genome Sequencing to Inform the Integration of Genomics into Care

INTRODUCTION

The growth of global sequencing initiatives and commercial genomic test offerings suggests the public will increasingly be confronted with decisions about sequencing. Understanding public attitudes can assist efforts to integrate sequencing into care and inform the development of public education and outreach strategies.

METHODS

A 48-item online survey was advertised on Facebook in Eastern Canada and hosted on SurveyMonkey in late 2018. The survey measured public interest in whole genome sequencing and attitudes toward various aspects of sequencing using vignettes, scaled, and open-ended items.

RESULTS

While interest in sequencing was high, critical attitudes were observed. In particular, items measuring features of patient control and choice regarding genomic data were strongly endorsed by respondents. Majority wanted to specify upfront how their data could be used, retain the ability to withdraw their sample at a later date, sign a written consent form, and speak to a genetic counselor prior to sequencing. Concerns about privacy and unauthorized access to data were frequently observed. Education level was the sociodemographic variable most often related to attitude statements such that those with higher levels of education generally displayed more critical attitudes.

CONCLUSIONS

Attitudes identified here could be used to inform the development of implementation strategies for genomic medicine. Findings suggest health systems must address patient concerns about privacy, consent practices, and the strong desire to control what happens to their genomic data through public outreach and education. Specific oversight procedures and policies that are clearly communicated to the public will be required.

COVID-19 antibody seroprevalence in Santa Clara County, California

BACKGROUND

Measuring the seroprevalence of antibodies to Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is central to understanding infection risk and fatality rates. We studied Coronavirus Disease 2019 (COVID-19)-antibody seroprevalence in a community sample drawn from Santa Clara County.

METHODS

On 3 and 4 April 2020, we tested 3328 county residents for immunoglobulin G (IgG) and immunoglobulin M (IgM) antibodies to SARS-CoV-2 using a rapid lateral-flow assay (Premier Biotech). Participants were recruited using advertisements that were targeted to reach county residents that matched the county population by gender, race/ethnicity and zip code of residence. We estimate weights to match our sample to the county by zip, age, sex and race/ethnicity. We report the weighted and unweighted prevalence of antibodies to SARS-CoV-2. We adjust for test-performance characteristics by combining data from 18 independent test-kit assessments: 14 for specificity and 4 for sensitivity.

RESULTS

The raw prevalence of antibodies in our sample was 1.5% [exact binomial 95% confidence interval (CI) 1.1-2.0%]. Test-performance specificity in our data was 99.5% (95% CI 99.2-99.7%) and sensitivity was 82.8% (95% CI 76.0-88.4%). The unweighted prevalence adjusted for test-performance characteristics was 1.2% (95% CI 0.7-1.8%). After weighting for population demographics, the prevalence was 2.8% (95% CI 1.3-4.2%), using bootstrap to estimate confidence bounds. These prevalence point estimates imply that 53 000 [95% CI 26 000 to 82 000 using weighted prevalence; 23 000 (95% CI 14 000-35 000) using unweighted prevalence] people were infected in Santa Clara County by late March-many more than the ∼1200 confirmed cases at the time.

CONCLUSION

The estimated prevalence of SARS-CoV-2 antibodies in Santa Clara County implies that COVID-19 was likely more widespread than indicated by the number of cases in late March, 2020. At the time, low-burden contexts such as Santa Clara County were far from herd-immunity thresholds.

On 3 and 4 April 2020, we tested 3328 county residents for immunoglobulin G (IgG) and immunoglobulin M (IgM) antibodies to SARS-CoV-2 using a rapid lateral-flow assay (Premier Biotech). Participants were recruited using advertisements that were targeted to reach county residents that matched the county population by gender, race/ethnicity and zip code of residence. We estimate weights to match our sample to the county by zip, age, sex and race/ethnicity. We report the weighted and unweighted prevalence of antibodies to SARS-CoV-2. We adjust for test-performance characteristics by combining data from 18 independent test-kit assessments: 14 for specificity and 4 for sensitivity.

RESULTS

The raw prevalence of antibodies in our sample was 1.5% [exact binomial 95% confidence interval (CI) 1.1-2.0%]. Test-performance specificity in our data was 99.5% (95% CI 99.2-99.7%) and sensitivity was 82.8% (95% CI 76.0-88.4%). The unweighted prevalence adjusted for test-performance characteristics was 1.2% (95% CI 0.7-1.8%). After weighting for population demographics, the prevalence was 2.8% (95% CI 1.3-4.2%), using bootstrap to estimate confidence bounds. These prevalence point estimates imply that 53 000 [95% CI 26 000 to 82 000 using weighted prevalence; 23 000 (95% CI 14 000-35 000) using unweighted prevalence] people were infected in Santa Clara County by late March-many more than the ∼1200 confirmed cases at the time.

CONCLUSION

The estimated prevalence of SARS-CoV-2 antibodies in Santa Clara County implies that COVID-19 was likely more widespread than indicated by the number of cases in late March, 2020. At the time, low-burden contexts such as Santa Clara County were far from herd-immunity thresholds.

Social Media Use for Health Purposes: Systematic Review

Background

Social media has been widely used for health-related purposes, especially during the COVID-19 pandemic. Previous reviews have summarized social media uses for a specific health purpose such as health interventions, health campaigns, medical education, and disease outbreak surveillance. The most recent comprehensive review of social media uses for health purposes, however, was conducted in 2013. A systematic review that covers various health purposes is needed to reveal the new usages and research gaps that emerge in recent years.

Objective

This study aimed to provide a systematic review of social media uses for health purposes that have been identified in previous studies.

Methods

The researchers searched for peer-reviewed journal articles published between 2006 and 2020 in 12 databases covering medicine, public health, and social science. After coding the articles in terms of publication year, journal area, country, method, social media platform, and social media use for health purposes, the researchers provided a review of social media use for health purposes identified in these articles.

Results

This study summarized 10 social media uses for various health purposes by health institutions, health researchers and practitioners, and the public.

Conclusions

Social media can be used for various health purposes. Several new usages have emerged since 2013 including advancing health research and practice, social mobilization, and facilitating offline health-related services and events. Research gaps exist regarding advancing strategic use of social media based on audience segmentation, evaluating the impact of social media in health interventions, understanding the impact of health identity development, and addressing privacy concerns.

Household chaos, maternal stress, and maternal health behaviors in the United States during the COVID-19 outbreak

Objectives:

Household chaos, including disorder, noise, and crowding within the home, is a risk factor for poor mental and physical health. Household chaos may act upon maternal behaviors of physical activity and sleep, potentially via higher stress. The purpose of this study is to evaluate the relationships among household chaos, maternal stress, and maternal physical activity and sleep, and identify barriers to home organization during the COVID-19 outbreak.

Methods:

A cross-sectional study using an online survey of 1721 mothers of preschoolers (ages = 3.0–5.9 years) in the United States was conducted in May 2020 during COVID-19 stay-at-home orders and early reopening. Mothers reported demographic characteristics, household chaos, stress, physical activity and sleep, and barriers to home organization during the outbreak. Mediation models were conducted among household chaos, stress, and physical activity and sleep with adjustment for covariates.

Results:

About half of mothers were middle income (48.2%), employed full-time prior to the outbreak (59.1%), and met the physical activity (47.7%), and sleep guideline (49.7%, 7–9 h/day). Household chaos and stress were both negatively related to physical activity and sleep. For every 1 unit increase in mother’s current stress, mothers were 11% (95% confidence interval = 6% to 16%) less likely to meet the physical activity guideline and 19% (95% confidence interval = 14% to 23%) less likely to meet the sleep guideline. Household chaos was positively related to stress. Stress partially mediated the relationship between household chaos and physical activity and sleep. Virus concerns, occupational changes (i.e. teleworking), and lack of childcare were barriers to home organization.

Conclusion:

During the COVID-19 outbreak, many mothers had poor sleep and physical activity, which was associated with household chaos and stress. Opportunities to promote order at the individual, household, and community level may result in beneficial mental and physical health in mothers of young children during the COVID-19 outbreak and beyond.

Household chaos, family routines, and young child movement behaviors in the U.S. during the COVID-19 outbreak: a cross-sectional study

BACKGROUND

The home environment is an important facilitator of young child movement behaviors, including physical activity (PA), sleep, and screen-time. Household chaos, characterized by crowding, noise, and disorder in the home, may hinder efforts to obtain adequate amounts of movement behaviors. The COVID-19 outbreak impacted many families, and social distancing during this time may create conditions for more household chaos. Family routines can help establish order in the home and encourage an appropriate balance of movement behaviors, such as less screen-time and more sleep. The purpose of this study was to evaluate the association between household chaos and young child movement behaviors during the COVID-19 outbreak in the United States, and the role of family routines in this relationship.

METHODS

A national online survey including 1836 mothers of preschoolers (3.0-5.9 years) was conducted during May 2020. Mothers reported demographic characteristics, household chaos, family routines, and the preschooler's movement behaviors during the outbreak. Mothers completed a household chaos questionnaire and were grouped into chaos categories (low, moderate/low, moderate/high, and high) for analysis. Linear regression was used to assess the association between chaos category, family routines, and movement behaviors with adjustment for covariates.

RESULTS

Mothers were 35.9 ± 4.1 years of age, middle income (47.8%), and preschoolers were 3.8 ± 0.8 years of age. Most mothers reported their preschooler was less physically active (38.9%), slept the same amount of time (52.1%), and increased their screen-time (74.0%) after the COVID-19 outbreak. Preschoolers in the high chaos households performed less total PA (β = - 0.36 days/week, 95% CI:-0.62 to - 0.09, p = 0.008), slept less (β = - 0.42 h, 95% CI:-0.59 to - 0.25, p = 0.001) and had more screen-time (β = 0.69 h, 95% CI:0.45 to 0.92, p = 0.001) compared to those in low chaos households. In most chaos categories, having a bed-time ritual was related to more child sleep, and mothers who viewed routines as "less/not important" reported more preschooler screen-time compared to mothers who viewed routines as "very important".

CONCLUSION

Promoting bed-time rituals and prioritizing routines, even somewhat, may be related to an improved balance of child movement behaviors. Innovative measures are needed to support families during periods of disruption such as that experienced in the COVID-19 pandemic.

A Minority Stress Response Model of Health Behaviors in Gay and Bisexual Men: Results from a Taiwanese Sample

Purpose: Health disparities among sexual minority men remain and continue to demand novel interventions. Other than risk reduction, a promising approach is to identify pathways to health-promoting behaviors. In this study, depressive symptoms, internalized homophobia, and sense of community connectedness were hypothesized to result from the experience of harassment and rejection, and in turn either promote or inhibit an individual's tendency toward health-promoting behaviors. We accounted for subgroup differences by examining the hypothesized model in gay and bisexual men separately. Methods: This was a cross-sectional survey study. One thousand three hundred eighty-one gay (81.5%) and bisexual (18.5%) Taiwanese men 18-49 years of age (mean = 26.56, standard deviation = 6) were recruited through a social media advertisement and completed an online survey. Structural equation modeling was employed to simultaneously examine multiple hypothesized paths. Results: Harassment and rejection were associated with greater depressive symptoms, internalized homophobia, and sense of community connectedness, which in turn yielded direct or indirect associations with health-promoting behavior among gay men. For bisexual men, depressive symptoms remained an important mechanism linking harassment and rejection and health-promoting behavior, whereas the roles of internalized homophobia and sense of community connectedness appeared less obvious. Conclusion: These findings cast new light on the behavioral implications of minority stress and elucidate the possible underlying mechanisms. The study suggests that more effort should be invested to understand and promote the drivers of health-promoting behavior to reduce health disparities in this population.

Risk of COVID-19-related bullying, harassment and stigma among healthcare workers: an analytical cross-sectional global study

OBJECTIVES

Essential healthcare workers (HCW) uniquely serve as both COVID-19 healers and, potentially, as carriers of SARS-CoV-2. We assessed COVID-19-related stigma and bullying against HCW controlling for social, psychological, medical and community variables.

DESIGN

We nested an analytical cross-sectional study of COVID-19-related stigma and bullying among HCW within a larger mixed-methods effort assessing COVID-19-related lived experience and impact. Adjusted OR (aOR) and 95% CIs evaluated the association between working in healthcare settings and experience of COVID-19-related bullying and stigma, controlling for confounders. Thematic qualitative analysis provided insight into lived experience of COVID-19-related bullying.

SETTING

We recruited potential participants in four languages (English, Spanish, French, Italian) through Amazon Mechanical Turk's online workforce and Facebook.

PARTICIPANTS

Our sample included 7411 people from 173 countries who were aged 18 years or over.

FINDINGS

HCW significantly experienced more COVID-19-related bullying after controlling for the confounding effects of job-related, personal, geographic and sociocultural variables (aOR: 1.5; 95% CI 1.2 to 2.0). HCW more frequently believed that people gossip about others with COVID-19 (OR: 2.2; 95% CI 1.9 to 2.6) and that people with COVID-19 lose respect in the community (OR: 2.3; 95% CI 2.0 to 2.7), both which elevate bullying risk (OR: 2.7; 95% CI 2.3 to 3.2, and OR: 3.5; 95% CI 2.9 to 4.2, respectively). The lived experience of COVID-19-related bullying relates frequently to public identities as HCW traverse through the community, intersecting with other domains (eg, police, racism, violence).

INTERPRETATION

After controlling for a range of confounding factors, HCW are significantly more likely to experience COVID-19-related stigma and bullying, often in the intersectional context of racism, violence and police involvement in community settings.

Anosmia and other SARS-CoV-2 positive test-associated symptoms, across three national, digital surveillance platforms as the COVID-19 pandemic and response unfolded: an observation study

Background

Multiple participatory surveillance platforms were developed across the world in response to the COVID-19 pandemic, providing a real-time understanding of community-wide COVID-19 epidemiology. During this time, testing criteria broadened and healthcare policies matured. We sought to test whether there were consistent associations of symptoms with SARS-CoV-2 test status across three national surveillance platforms, during periods of testing and policy changes, and whether inconsistencies could better inform our understanding and future studies as the COVID-19 pandemic progresses.

Methods

Four months (1st April 2020 to 31st July 2020) of observation through three volunteer COVID-19 digital surveillance platforms targeting communities in three countries (Israel, United Kingdom, and United States). Logistic regression of self-reported symptom on self-reported SARS-CoV-2 test status (or test access), adjusted for age and sex, in each of the study cohorts. Odds ratios over time were compared to known changes in testing policies and fluctuations in COVID-19 incidence.

Findings

Anosmia/ageusia was the strongest, most consistent symptom associated with a positive COVID-19 test, based on 658,325 tests (5% positive) from over 10 million respondents in three digital surveillance platforms using longitudinal and cross-sectional survey methodologies. During higher-incidence periods with broader testing criteria, core COVID-19 symptoms were more strongly associated with test status. Lower incidence periods had, overall, larger confidence intervals.

Interpretation

The strong association of anosmia/ageusia with self-reported SARS-CoV-2 test positivity is omnipresent, supporting its validity as a reliable COVID-19 signal, regardless of the participatory surveillance platform or testing policy. This analysis highlights that precise effect estimates, as well as an understanding of test access patterns to interpret differences, are best done only when incidence is high. These findings strongly support the need for testing access to be as open as possible both for real-time epidemiologic investigation and public health utility.

SMEs’ International Strategic Groups and Top Managers’ Psychological Characteristics

This research analyzed the small and medium-sized enterprises’ (SMEs) international strategies concerning the scale and scope of the international activities. The major purpose was to study the international top managers’ psychological characteristics as distinctive capabilities within the defined international strategic groups. The international top managers’ cultural intelligence and emotional intelligence were taken as main characteristics to act in the international business environment. Therefore, we took as the main motivation to perform the present investigation the need to understand which psychological characteristics may help the international top managers to pursue high degrees of internationalization in their firms. This study was conducted in Portugal, and the sample was composed of 307 Portuguese SMEs’ international top managers directly responsible for the firms’ international decisions. The multinomial logistic regression method was used to test the hypotheses. The firms were classified into three international strategic groups based on the internationalization scale and scope. The degree of internationalization reflects that combination, creating groups with a high, medium, and low international exposure. The main result indicates as a distinctive capability, the international top managers’ cultural intelligence within the firms that exhibit a high international strategic positioning. Regarding the main contributions, this article contributes to the bodies of knowledge of international SMEs, cultural intelligence, emotional intelligence, and networking. This study also contributes to upper echelons theory and the resource-based view.

Sociodemographics and their impacts on risk factor awareness and beliefs about cancer and screening: results from a cross-sectional study in Newfoundland and Labrador

Background

Our objective was to examine cancer risk factor awareness and beliefs about cancer treatment, outcomes, and screening, and how these are mediated by sociodemographic variables, among Newfoundland and Labrador residents.

Methods

Participants aged 35 to 74 were recruited through Facebook advertising, and a self-administered online questionnaire was used to collect data. Descriptive statistics, Spearman rank correlations, and multivariate logistic regression analyses were performed.

Results

Of the 1048 participants who responded and met the inclusion criteria for this study, 1019 were selected for this analysis. Risk factor recognition was generally good, though several risk factors had poor awareness: being over 70 years old (53.4% respondents aware), having a low-fiber diet (65.0%), and drinking more than 1 unit of alcohol per day (62.8%). Our results showed that the participants’ awareness of risk factors was significantly associated with higher income level (r_s = 0.237, P <  0.001), higher education (r_s = 0.231, P <  0.001), living in rural regions (r_s = 0.163, P <  0.001), and having a regular healthcare provider (r_s = 0.081, P = 0.010). Logistic regression showed that among NL residents in our sample, those with higher income, post-secondary education, those in very good or excellent health, and those with a history of cancer all had higher odds of having more positive beliefs about cancer treatment and outcomes. Those with a history of cancer, and those with very good or excellent health, also had higher odds of having more positive beliefs about cancer screening. Finally, compared to Caucasian/white participants, those who were non-Caucasian/white had lower odds of having more positive beliefs about cancer screening.

Conclusion

Among adults in NL, there was poor awareness that low-fiber diets, alcohol, and age are risk factors for cancer. Lower income and education, rural residence, and not having a health care provider were associated with lower risk factor awareness. We also found a few associations between sociodemographic factors and beliefs about cancer treatment and outcomes or screening. We stress that while addressing awareness is necessary, so too is improving social circumstances of disadvantaged groups who lack the resources necessary to adopt healthy behaviours.

Running field experiments using Facebook split test

Business researchers use experimental methods extensively due to their high internal validity. However, controlled laboratory and crowdsourcing settings often introduce issues of artificiality, data contamination, and low managerial relevance of the dependent variables. Field experiments can overcome these issues but are traditionally time- and resource-consuming. This primer presents an alternative experimental setting to conduct online field experiments in a time- and cost-effective way. It does so by introducing the Facebook A/B split test functionality, which allows for random assignment of manipulated variables embedded in ecologically-valid stimuli. We compare and contrast this method against laboratory settings and Amazon Mechanical Turk in terms of design flexibility, managerial relevance, data quality control, and sample representativeness. We then provide an empirical demonstration of how to set up, pre-test, run, and analyze FBST experiments.

Oxygen therapy practices in the acutely ill medical patients: A social media-based nationwide study of clinicians’ preferences and summary of current recommendations

Oxygen is the most commonly used drug in emergency medicine. The aim of this study was to identify healthcare professionals’ preferences regarding oxygen therapy in common medical emergencies. An online 9-part-questionnaire was distributed through Facebook to doctors and nurses working in Greek hospitals. The questionnaire included background information of the respondents and addressed individual preferences regarding best oxygenation parameter and oxygen targets in specific acute settings. We received 678 responses and we included 663 in our analysis. We found significant differences between doctors’ and nurses’ attitudes towards oxygenation targets in ARDS, sepsis, acute coronary syndrome, and post cardiac-arrest patients. Nurses preferred a more conservative oxygen strategy compared to doctors. Furthermore, nurses favor SaO2 as the best oxygenation parameter, while doctors prefer PaO2. In our survey, the type of hospital and department of the respondents did not affect the preferred oxygen strategy. Social media-based survey research is feasible and effective. In this single country study, doctors showed a tendency to liberally administer oxygen in acutely ill medical patients. On the other hand, Greek nurses preferred a more conservative approach.

Individual Circadian Preference, Shift Work, and Risk of Medication Errors: A Cross-Sectional Web Survey among Italian Midwives

BACKGROUND

In order to explore the possible association between chronotype and risk of medication errors and chronotype in Italian midwives, we conducted a web-based survey. The questionnaire comprised three main components: (1) demographic information, previous working experience, actual working schedule; (2) individual chronotype, either calculated by Morningness-Eveningness Questionnaire (MEQ); (3) self-perception of risk of medication error.

RESULTS

Midwives (n = 401) responded "yes, at least once" to the question dealing with self-perception of risk of medication error in 48.1% of cases. Cluster analysis showed that perception of risk of medication errors was associated with class of age 31-35 years, shift work schedule, working experience 6-10 years, and Intermediate-type MEQ score.

CONCLUSIONS

Perception of the risk of medication errors is present in near one out of two midwives in Italy. In particular, younger midwives with lower working experience, engaged in shift work, and belonging to an Intermediate chronotype, seem to be at higher risk of potential medication error. Since early morning hours seem to represent highest risk frame for female healthcare workers, shift work is not always aligned with individual circadian preference. Assessment of chronotype could represent a method to identify healthcare personnel at higher risk of circadian disruption.
