RESUMEN

BACKGROUND: Tumor genomic profiling (TGP) identifies targets for precision cancer treatments, but also secondary hereditary risks. Oncologists are poorly trained to communicate the results of TGP, especially among patients with lower health literacy, poorer genetics knowledge, and higher mistrust. African American (AA) patients are especially vulnerable to poor understanding due to significant cancer disparities and lower uptake of TGP. The goal of this research is to inform the development of an internet-based brief educational support for oncologists to prepare them to provide better decisional support related to TGP for their AA cancer patients. METHODS: This mixed-methods study used semi-structured interviews of oncologists to inform development of an online survey with a convenience sample of US-based oncologists (n = 50) to assess perceptions of the challenges of TGP and communicating results to AA patients. RESULTS: Most interviewed oncologists felt it was important to consider racial/cultural differences when communicating about hereditary risks. Cost, family dynamics, discrimination concerns, and medical mistrust were identified as particularly salient. Survey respondents' views related to AAs and perceptions of TGP were strongly associated with years since completing training, with recent graduates expressing stronger agreement with statements identifying barriers/disadvantages to TGP for AA patients. CONCLUSIONS: Oncologists who had more recently completed training expressed more negative perceptions of TGP and more perceived challenges in communicating about TGP with their AA patients. Focused training for oncologists that addresses barriers specific to AAs may be helpful in supporting improved communication about TGP and improved decisional support for AA patients with cancer considering TGP to evaluate their tumors.

RESUMEN

The development of deep-sea floating offshore wind power (FOWP) is the key to fully utilizing water resources to enhance wind resources in the years ahead, and then the project is still in its initial stage, and identifying risks is a crucial step before promoting a significant undertaking. This paper proposes a framework for identifying risks in deep-sea FOWP projects. First, this paper identifies 16 risk criteria and divides them into 5 groups to establish a criteria system. Second, hesitant fuzzy linguistic term set (HFLTS) and triangular fuzzy number (TFN) are utilized to gather and describe the criterion data to ensure the robustness and completeness of the criterion data. Third, extending the method for removal effects of criteria (MEREC) to the HFLTS environment through the conversion of TFNs, under the influence of subjective preference and objective fairness, a weighting method combining analytic network process (ANP) and MEREC is utilized to calculate criteria weights, and the trust relationship and consistency between experts are used to calculate the expert weights to avoid the subjective weighting given by experts arbitrariness. Fourth, the study's findings indicated that the overall risk level of the deep-sea FOWP projects is "medium." Fifth, sensitivity and comparative analyses were conducted to test the reliability of the assessment outcomes. lastly, this research proposes risk management measures for the deep-sea FOWP project's establishment from economic, policy, technology, environment, and management aspects.

RESUMEN

BACKGROUND: Public health initiatives require coordinated efforts from healthcare, social services and other service providers. Organisational theory tells us that trust is essential for reaching collaborative effectiveness. This paper explores the drivers for initiating and sustaining trust in a temporary public health partnership, in response to a sudden health threat. METHODS: This qualitative study analysed the formation process of a multisector partnership for a Covid-19 contact tracing service. Data was collected through 12 interviews, two focus groups, one feedback workshop, and an online survey with workforce members from all seven partner organisations. Purposive maximum variation sampling was used to capture the reflections and experiences of workforce members from all seven partner organisations. A deductive code scheme was used to identify drivers for building and sustaining trust in inter-organisational collaboration. RESULTS: Relational mechanisms emanating from the commitment to the common aim, shared norms and values, and partnership structures affected trust-building. Shared values and the commitment to the common aim appeared to channel partners' behaviour when interacting, resulting in being perceived as a fair, reliable and supportive partner. Shared values were congruent with the design of the partnership in terms of governance structure and communication lines reflecting flat hierarchies and shared decision-making power. Tensions between partner organisations arose when shared values were infringed. CONCLUSIONS: When managing trust in a collaboration, partners should consider structural components like governance structure, organisational hierarchy, and communication channels to ensure equal power distribution. Job rotation, recruitment of candidates with the desired personality traits and attitudes, as well as training and development, encourage inter-organisational networking among employees, which is essential for building and strengthening relationships with partner organisations. Partners should also be aware of managing relational dynamics, channelling behaviours through shared values, objectives and priorities and fostering mutual support and equality among partner organisations.

RESUMEN

Background: Health beliefs may mediate the relationship between trust and vaccination decisions, as confidence in online health information has expanded quickly. However, little is known about how health attitudes and trust in health information affect COVID-19 vaccine intention. This study aimed to assess the effect of health beliefs and trust in information sources on the willingness to receive a COVID-19 vaccine among the general public in Saudi Arabia. Methods: This study was designed and carried out at the Faculty of Medicine, King Abdulaziz University, Jeddah, Saudi Arabia. Selected items were extracted from the Saudi Residents' Intention to Get Vaccinated Against COVID-19 (SRIGVAC) survey. They were categorized and validated into constructs of a health belief model (the perceived threat of COVID-19, vaccine-related benefits, barriers, and safety concerns) and trust in health information (from online platforms and health authorities/providers). Regression analysis and parallel mediation were used to assess the predictors of vaccination intentions. Results: Based on the responses of 3,091 participants, vaccine-related barriers and safety concerns negatively influenced vaccination intention, whereas vaccine benefits and the perceived threat of COVID-19 were positively correlated with vaccination intention. Trust in online health information had a direct relationship with intentions (ß = 0.09, p < 0.0001) as well as indirect relationships through the perceived benefits (ß = 0.095), the perceived barriers (ß = -0.029), and the perceived safety concerns toward the vaccine (ß = -0.010). The relationship between the willingness to vaccinate and trust in authentic information was fully mediated by all domains of health beliefs, with indirect coefficients of 0.004, 0.310, -0.134, and -0.031 for the perceived threat, vaccine benefits, barriers, and safety concerns, respectively. Conclusion: The relationship between the willingness to vaccinate and trust in authentic information was fully mediated by all domains of health beliefs. Vaccine coverage in Saudi Arabia can be optimized by targeting the health beliefs of the general public.

RESUMEN

Women living with serious mental illness (SMI) are at increased risk for adverse pregnancy and parenting outcomes. However, little is known about the experiences and preferences of women with SMI related to addressing pregnancy and parenting with their mental health providers. We conducted semistructured interviews with twenty-two reproductive-age cisgender women patients living with SMI. Participants characterized discussions about pregnancy and medication teratogenicity with their mental health providers as limited or unsatisfactory. Participants' openness to discussing pregnancy varied by topic and its perceived relevance to their individual circumstances, and it hinged on participants' trust in their providers. Participants characterized discussions about parenting with their mental health providers as helpful and identified additional opportunities for parenting support. Our findings highlight critical gaps in the delivery of information, support, and resources that can inform efforts to increase providers' capacity to address pregnancy and parenting with women living with SMI.

RESUMEN

BACKGROUND AND OBJECTIVES: Although digital health promises improved healthcare efficiency and equity, access and uptake might be low in disadvantaged populations. We measured access to digital health technology, the uptake of digital health, digital health literacy and COVID-19 vaccination intentions in an inner-city Australian population experiencing homelessness. METHOD: An existing Australian survey, including a validated digital health literacy measure (eHealth Literacy Scale [eHEALS]), was modified and distributed in three general practices specifically targeting the homeless population. Data analysis used appropriate descriptive statistics and correlation coefficients. RESULTS: Eighty-three respondents completed the survey in 2021. Digital health uptake was much lower than in the general Australian population in 2019-20, despite good access to working smart phones and connectivity. Digital health literacy was positively associated with uptake. Internet-sourced information was trusted less than information from a general practitioner. DISCUSSION: Further work is needed to understand the perceived usefulness and sociocultural compatibility of digital health in different subpopulations experiencing homelessness, including susceptibility to misinformation.

RESUMEN

We assessed university students' knowledge, attitude, and practice toward blood donation and identified the factors that promote or hinder their willingness to donate. We employed a multicenter cross-sectional design, collecting data from August to October 2022 through self-administered questionnaires available in Arabic and English. Both online (Google Forms) and paper surveys were utilized. Data were analyzed using R Statistical Software (v4.1.3; R Core Team 2022). A total of 12,606 university students (7966 females and 4640 males) from 16 countries completed the questionnaire; of them, 28.5% had a good knowledge level regarding blood donation, and 22.7% had donated blood at least once. Students in health science colleges had significantly more awareness of blood donation (p-value < 0.001), but there were no significant differences in practice (p-value = 0.8). Barriers to donation included not being asked (37%), medical ineligibility (33%), fear of pain or infection (18%), concerns about negative health effects (18%), difficulty accessing donation centers (15%), and medical mistrust (14%). Individuals aged > 20 years had significantly higher odds of possessing a high knowledge level (adjusted odds ratio [aOR] 1.77, p < 0.001). Private and international university enrollment was associated with increased knowledge (aOR 1.19, p-value < 0.001 and aOR 1.44, p-value = 0.003), while non-health science college students had lower odds (aOR 0.36, p < 0.001). Regarding blood donation status, participants > 20 years old were more likely to donate (aOR 2.21, p < 0.001). Conversely, being female, having congenital or chronic diseases, and possessing low knowledge levels were associated with decreased odds of blood donation (all p < 0.05). University students show insufficient knowledge about blood donation, with health science students displaying higher awareness levels. Despite their positive attitudes, blood donation rates remain low across all disciplines. It is imperative to enhance education and accessibility to foster a culture of blood donation among students.

RESUMEN

BACKGROUND: Increasing rates of maternal mortality and morbidity, coupled with ever-widening racial health disparities in maternal health outcomes, indicate that radical improvements need to be made in the delivery of maternity care. This study explored the provision of patient-centered maternity care from the perspective of pregnant and postpartum people; experiences of respect and autonomy were examined through the multi-dimensional contexts of identity, relational trust, and protection of informed choices. METHODS: We conducted primary data collection among individuals who experienced a pregnancy in the five years preceding the survey (N = 484) using the validated Mothers on Respect Index (MORi) and Mothers Autonomy in Decision Making (MADM) scale. We conducted an exploratory factor analysis (EFA) which produced three factor variables: trust, informed choice, and identity. Using these factor variables as dependent variables, we conducted bivariate and multivariate analysis to examine the relationship between these factor variables and social marginalization, as measured by race, disability, justice-involvement, and other social risk factors, such as food and housing insecurity. RESULTS: Results of our bivariate and multivariate models generally confirmed our hypothesis that increased social marginalization would be associated with decreased experiences of maternity care that was perceived as respectful and protective of individual autonomy. Most notably, AI/AN individuals, individuals who are disabled, and individuals who had at least one social risk factor were more likely to report experiencing identity-related disrespect and violations of their autonomy. CONCLUSIONS: In light of the findings that emphasize the importance of patient identity in their experience in the healthcare system, patient-centered and respectful maternity care must be provided within a broader social context that recognizes unequal power dynamics between patient and provider, historical trauma, and marginalization. Provider- and facility-level interventions that improve patient experiences and health outcomes will be more effective if they are contextualized and informed by an understanding of how patients' identities and traumas shape their healthcare experience, health-seeking behaviors, and potential to benefit from clinical interventions and therapies.

RESUMEN

This replication revisits an influential contribution on the intergenerational transmission of risk and trust attitudes, which, based on data from the German Socioeconomic Panel (GSOEP), reveals a positive correlation between parents' and children's attitudes. The authors of the original study argue that socialization in the family is important in the transmission process. The replication is motivated by mounting evidence indicating that within-family transmission has a considerable genetic component, which calls into question socialization as the main transmission pathway. To consider genetic transmission in addition to social transmission, the replication relies on the German twin family panel TwinLife. The findings reveal that, first, most of the variation in children's risk and social trust attitudes is attributable to differences in the non-shared environment, followed by genetic differences, whereas differences in the shared family environment - the main candidate for social transmission - do not matter. Second, correlations between parents' and children's attitudes essentially involve genetic similarity. Third, family conditions do not moderate these relationships. Thus, the findings do not support the socialization assumption.

RESUMEN

Using the Consequences of COVID-19 (COCO) dataset (quota sample of the adult Italian population, surveyed seven times by email), we analysed the trend of trust in political (political parties, parliament and local administrations), super partes (president of the Republic, judiciary and police) and international (the European Union and the United Nations) institutions from June 2019 to October 2022. Three latent growth curve models showed that trust in political institutions increased between June 2019 and April 2020 and subsequently decreased below the pre-pandemic level. Trust in super partes institutions decreased slightly between June 2019 and April 2020, decreased from April 2020 to April 2022 and increased in the subsequent months. Trust in international institutions declined between June 2019 and April 2020 and then returned to pre-pandemic levels. Three piecewise decompositions showed different trends in trust for non-populist voters, populist voters and non-voters. Strengths, weaknesses and possible developments of the study are discussed.

RESUMEN

When deciding whether to reciprocate trust, people are typically strongly influenced by how much trust their interaction partner has originally shown them. If a partner has placed a lot of trust in you, there is a strong motivation to reciprocate, and indeed this factor often outweighs pro-self considerations to maximize one's own financial payout. However, one important unanswered question in this regard is what people decide to do when this prior information is ambiguous; that is, when they do not know for sure exactly how trusting their partner has been. How then do people decide to reciprocate? This study utilizes a novel version of the Trust Game to directly address this question. Here, we develop, and validate, a computational model-based approach to quantify and categorize how participants assessed the trustworthiness of an unfamiliar partner when making reciprocity decisions. We find that participants spontaneously use their prior experience about the trustingness of game partners in general to inform their reciprocity decisions, even when they had the opportunity to strategically assume that their new, unfamiliar, partners were untrusting, and hence could have justified lower reciprocation rates.

RESUMEN

BACKGROUND: Existing research has extensively explored the relationship between government trust and compliance behaviour, but significant controversies exist. Some studies suggest a strong positive correlation between the two. Other studies have found that government trust hinders compliance behaviour. However, during the pandemic, the effectiveness of public health policies largely depends on the public's compliance with these policies. To examine the aforementioned controversies, this study utilizes survey data on the Chinese population during the COVID-19 period to explore the relationship between compliance with public health policies and government trust. METHODS: The study conducted a questionnaire survey of 1,395 individuals from 25 provinces in China from mid-November to mid-December 2022. Firstly, we categorized the public's compliance behaviour with public health policies based on the results of factor analysis. Subsequently, we examined the impact of government trust and professional trust on compliance behaviour with public health policies by constructing a structural equation model. RESULTS: Based on the results of factor analysis, we classified public adherence to public health policies into protective compliance and restrictive compliance. Results from the structural equation model show a positive correlation between the public's trust in the government and both protective and restrictive compliance, with a stronger influence on protective compliance. Government trust also exerts a positive impact on restrictive compliance behaviour through professional trust. Additionally, the study indicates a significant positive correlation between the public's professional trust and restrictive compliance, while it does not significantly affect protective compliance. Moreover, the public from rural areas demonstrates a greater willingness to adhere to both types of public health policies. Married individuals exhibit a stronger inclination toward protective compliance, while females show a stronger tendency toward restrictive compliance. CONCLUSION: The study revealed a significant positive impact of government trust and professional trust on compliance behaviour with public health policies during the COVID-19 pandemic, refuting any negative correlation between government trust and compliance behaviour. Normative motivations for compliance behaviour had a substantial impact on adherence. These findings offer valuable insights for future public health crisis management and public policy formulation.

RESUMEN

This study addresses the effects of blindness on trust. Using an auditory version of the multi-round Trust Game, we investigated the effect of reputation and reciprocity on trust decisions in early blind and sighted participants. During each round of the game, participants were endowed with a sum of money and had to decide how much they wanted to invest in their partners, who were manipulated as a function of their good or bad reputation and individualistic or cooperative behavior. The data showed that negative first impression about the partner (bad reputation and/or selfish behavior) impacted more blind participants than sighted ones. However, following repeated interactions with the partners, the overall mean investment aligned between the blind and sighted groups. We interpret these findings as suggesting that blindness may guide participants to a more cautionary behavior when dealing with partners with negative initial characteristics.

RESUMEN

Public acceptance plays an essential role in successfully constructing and operating innovative and evolving technologies that promote ecological sustainability and pollution reduction. The present study investigates the factors influencing public acceptance of plastic waste-to-energy gasification projects. The research added social trust and health consciousness to the theory of planned behavior. Using the structural equation modeling, 513 valid survey questionnaire responses from the Beijing-Tianjin-Hebei region, China, were analyzed. The most notable results reveal that attitude, social norms, and perceived behavioral control have a major impact on the public acceptability of the initiative. There was no correlation between social trust and public support for the project. Social trust affects public acceptance of the project through attitude. Health consciousness was shown to be favorably connected with public approval of the project both directly and indirectly through attitude. This study serves policymakers and stakeholders with robust policy recommendations to promote public acceptance of plastic waste-to-energy gasification schemes and other hazardous facilities.

RESUMEN

Background: Communication abilities, organizational intimacy, trust among colleagues, and job satisfaction of nurses in comprehensive nursing care service units are emphasized more than any other ward, and research on this is necessary. Objective: The study was to examine the influences of communication ability, organizational intimacy, and trust among colleagues on the job satisfaction of nurses in the comprehensive nursing care service units. Methods: This study used a cross-sectional descriptive design. The participants were 155 nurses caring for patients in the comprehensive nursing care service units in Seoul. Measures included the general characteristics of study participants, communication ability, organizational intimacy, trust among colleagues, and job satisfaction. The data were analyzed using the SPSS/WIN version 27.0 program. The data collection period was from August to September 2022. Results: Factors influencing the job satisfaction of nurses at the comprehensive nursing care service units were organizational intimacy (ß = 0.36), communication abilities (ß = 0.26), trust among colleagues (ß = 0.22), and the average number of patients assigned to a nurse (ß = -0.19), which explained 67% of the variance. Conclusions: Organizational intimacy was the greatest factor influencing the job satisfaction of nurses in the comprehensive nursing care service units. To increase the job satisfaction of ward nurses working in the comprehensive nursing care service, securing manpower is required, and it is necessary to provide effective nursing care with an average number of patients of 5 or less. In particular, a systematic job training program is needed to increase organizational intimacy among team nurses.

RESUMEN

The ability to predict whether a peptide will get presented on Major Histocompatibility Complex (MHC) class I molecules has profound implications in designing vaccines. Numerous deep learning-based predictors for peptide presentation on MHC class I molecules exist with high levels of accuracy. However, these MHC class I predictors are treated as black-box functions, providing little insight into their decision making. To build turst in these predictors, it is crucial to understand the rationale behind their decisions with human-interpretable explanations. We present MHCXAI, eXplainable AI (XAI) techniques to help interpret the outputs from MHC class I predictors in terms of input peptide features. In our experiments, we explain the outputs of four state-of-the-art MHC class I predictors over a large dataset of peptides and MHC alleles. Additionally, we evaluate the reliability of the explanations by comparing against ground truth and checking their robustness. MHCXAI seeks to increase understanding of deep learning-based predictors in the immune response domain and build trust with validated explanations.

RESUMEN

To explore the influencing factors of consumers' impulsive purchase behavior in live streaming, based on the Stimulus-Organism-Response framework, we construct the model of how streamers influence consumers' impulsive purchase behavior by consulting literature. Collected data by means of a questionnaire, and made an empirical study by using the structural equation model to explore the mechanism of streamer affecting consumers' impulsive purchase behavior. The results show that streamer characteristics (personal charisma, professionalism) and streamer performance (interactivity, entertainment) affect consumers' impulsive purchase behavior by affecting consumers' trust and flow experience. The empirical results have important theoretical and practical significance.

RESUMEN

During the Covid-19 crisis, citizens turned to Twitter for information seeking, emotional outlet and sense-making of the crisis, creating ad hoc social communities using crisis-specific hashtags. The theory of ambient affiliation posits that the use of hashtags upscales the call to affiliate with the values expressed in the tweet. Given the deep functional tie between values and emotions, hashtag use might further amplify certain emotions. While emotions in crises-hashtagged communities have been previously investigated, the hypothesis of amplification of emotions through hashtag use has not yet been tested. We investigate such effect during the Covid-19 crisis in a scenario of high-trust Nordic societies, focusing on non-hashtagged, crisis hashtagged (e.g., '#Covid-19') and threat hashtagged (e.g., '#misinformation') tweets. To do so we apply XLM-RoBERTa to estimate Anger, Fear, Sadness, Disgust, Joy and Optimism. Our results revealed that crisis-hashtagged (#Covid-19) tweets expressed more negative emotions (Anger, Fear, Disgust and Sadness) and less positive emotions (Optimism and Joy) than non-hashtagged Covid-19 tweets for all countries except Finland. Threat tweets (#misinformation) expressed even more negative emotions (Anger, Fear, Disgust) and less positive emotions (Optimism and Joy) than #Covid-19 tweets, with a particularly large effect for Anger. Our findings provide useful context for previous research on collective emotions during crises, as most Twitter content is not hashtagged, and given the faster spread of emotionally charged content, further support the special focus on specific ad hoc communities for crisis and threat management and monitoring.
