Development and Validation of the Perceived Interpersonal Relevancy Scales: A New Measure of Perceived Threat, Opportunity, and Invisibility Appraisals for Use Across the Adult Life-Course.

OBJECTIVES: Interpersonal relevancy appraisals are a dynamic and understudied aspect of human social cognition. Despite their importance, there are no existing measures. This study developed and validated a new measure of self-perceived interpersonal threat, opportunity, and invisibility appraisals among a life-course sample of adults. We also explored the relationships between relevance appraisals, social connectedness, loneliness, age, and sex-assigned-at-birth. METHOD: Items were developed based on a theoretical model of multi-domain interpersonal relevance appraisals and refined following feedback from five experts in social psychology. Cross-sectional data were obtained online from a sample of 1,079 adults (age 18-90 years), recruited from the general population of Australia. Data were split into two pseudo-random samples used for 1) scale development and evaluation, and 2) assessment of internal consistency, construct validity, convergent validity with social connectedness and loneliness, and exploratory analysis with age and sex. RESULTS: Results support the factor structure and internal consistency of 17- and 9-item versions of the Perceived Interpersonal Relevancy Scales (PIRS) and measurement invariance across younger and older age groups. Higher self-perceived threat and invisibility appraisals were associated with decreased social network size, increased loneliness, younger age, and male sex. Higher self-perceived opportunity appraisals were associated with increased social network size and decreased loneliness. DISCUSSION: Results support this new measure of perceived interpersonal relevance appraisals, which shows relationships between the way we believe others perceive us, loneliness, and social isolation. The PIRS likely has wide utility for studies that seek to understand the intersections between human social cognition, well-being, and health across the lifespan.

Secondary analysis of hand-offs in internal medicine using the I-PASS mnemonic.

BACKGROUND: Miscommunications account for up to 80% of preventable medical errors. Mnemonics like I-PASS (Illness severity, Patient summary, Actions list, Situation awareness, Synthesis) have demonstrated a positive impact on reducing error rates. Currently, physicians at our hospital do not follow a specific structure during hand-offs. We aimed to compare current hand-offs without prior training to a gold standard and the I-PASS tool in terms of content and sequence. METHODS: This study is a secondary analysis of data collected during a simulation study of a Friday evening hand-off to the night resident at University Hospitals of Geneva. Thirty physicians received a hand-off of four patients and managed two other patients through nursing pages at the start of the night shift, generating six sign-outs each, totaling 177 sign-outs. A focus group of three senior doctors defined the gold standard (GS) by consensus on the essential content of each sign-out. The analysis focused on the rates of relevance (ratio of information considered relevant by the GS) and completeness (proportion of transmitted elements out of all expected elements of the GS), and the distribution and sequence of the first four I-PASS categories. RESULTS: Relevance and completeness rates were 37.2% ± 0.07 and 51.9% ± 0.1, respectively, with no significant difference between residents and supervisors. There was a positive correlation between total hand-off time and relevance (residents: R2 = 0.62; supervisors: R2 = 0.67) and completeness (residents: R2 = 0.32; supervisors: R2 = 0.56). The distribution of I-PASS categories was highly skewed in both the GS (I = 2%, P = 72%, A = 17%, S = 9%) and participants (I = 6%, P = 73%, A = 14%, S = 7%), with significant differences in categories A (p = 0.046) and I (p ≤ 0.001). Sequences of I-PASS categories generally followed a P-A-S-I pattern. The first S category was frequently absent, and only one participant began by announcing the case severity as suggested by I-PASS. CONCLUSION: We identified gaps between current medical sign-outs in our institution's general internal medicine division and the I-PASS structure. We recommend implementing the I-PASS mnemonic, emphasizing the "I" category at the start and the "S" category to anticipate and prevent complications. Future studies should assess the impact of this recommendation, adapt the mnemonic elements to the context, and introduce specific hand-off training for senior medical students.

Orchestrating Relevance - Critique of a Questionable Trait of Modern Science Communication.

This essay critically analyzes the widespread phenomenon of claiming relevance when reporting original research. Specific examples from an area of method development in organofluorine chemistry demonstrate that the pursuit of worthiness of the corresponding research is mainly justified by putting forward a broad general industrial context that could potentially benefit in form of applications. However, it is deliberately ignored that such applications are in the vast majority of cases highly improbable or objectively unrealistic. Notwithstanding that scientists are nowadays often explicitly forced to orchestrate relevance, be it by researchfinancing institutions and/or journals' reviewers, it is argued that this is, from the point of view of research ethics at least, problematic.

The role of task relevance in saccadic responses to facial expressions.

Recent research on healthy individuals suggests that the valence of emotional stimuli influences behavioral reactions only when relevant to ongoing tasks, as they impact reaching arm movements and gait only when the emotional content cued the responses. However, it has been suggested that emotional expressions elicit automatic gaze shifting, indicating that oculomotor behavior might differ from that of the upper and lower limbs. To investigate, 40 participants underwent two Go/No-go tasks, an emotion discrimination task (EDT) and a gender discrimination task (GDT). In the EDT, participants had to perform a saccade to a peripheral target upon the presentation of angry or happy faces and refrain from moving with neutral ones. In the GDT, the same images were shown, but participants responded based on the posers' gender. Participants displayed two behavioral strategies: a single saccade to the target (92.7%) or two saccades (7.3%), with the first directed at a task-salient feature, that is, the mouth in the EDT and the nose-eyes regions in the GDT. In both cases, the valence of facial expression impacted the saccades only when relevant to the response. Such evidence indicates the same principles govern the interplay between emotional stimuli and motor reactions despite the effectors employed.

Risk factors and hearing outcomes in infants and young children in KwaZulu-Natal, South Africa.

BACKGROUND:  Targeted new-born hearing screening, based on high risk factors is recommended in the absence of universal new-born hearing screening in resource-constrained settings. The relevance of risk factors listed in the guidelines of high-income countries and used by low-middle income countries remains relatively unknown. Risk factors consistent with the epidemiological profile, evolution of risks and disease burden in these countries need to be considered. OBJECTIVES:  This study aimed to profile the frequency of risk factors and their manifestation in hearing outcomes of young children in the KwaZulu-Natal province of South Africa. METHOD:  A chart review of N = 1433 patients' archival audiology records was conducted, conveniently sampled from a single tertiary hospital (n = 351), a provincial assessment and therapy centre (n = 649), a university clinic (n = 291), and two schools for the deaf (n = 142). RESULTS:  Overall, 56% of the participants presented with either a conductive, sensorineural or a mixed hearing loss; 62% of the children had between 1 and 2 risk factors present (Mean [M] = 1.1; standard deviation [s.d.] = 0.98). Admission to neonatal intensive care unit, maternal infections, bacterial and viral infections and chemotherapy, from the Joint Committee on Infant Hearing list of high risk factors were significantly associated with hearing loss (p  0.05). Known non-JCIH risks, emerging risks and other statistically significant contextually relevant risk factors were also noted. CONCLUSION:  Understanding the profile of high risk factors in a given context has implications for prevention, early hearing identification and intervention services.Contribution: Targeted new-born hearing screening needs to be based on risk factors that are contextually relevant. This study is one of the first profiling high risk factors for hearing loss in children in KZN, the province with the second highest population in South Africa.

Modulatory effects of goal relevance on emotional attention reveal that fear has a distinct value.

Threat-related stimuli can capture attention. However, it remains debated whether this capture is automatic or not. To address this question, we compared attentional biases to emotional faces using a dot-probe task (DPT) where emotion was never goal-relevant (Experiment 1) or made directly task-relevant by means of induction trials (Experiments 2-3). Moreover, the contingency between the DPT and induction trials was either partial (Experiment 2) or full (Experiment 3). Eye-tracking was used to ascertain that the emotional cue and the subsequent target were processed with peripheral vision. Experiments 1 and 2 both showed that negative faces captured attention, with faster target processing when it appeared on the same side as the preceding fearful face (i.e. fear-valid trials) compared to the opposite side where the neutral face was shown (i.e. fear-invalid trials), but also when it appeared on the side of the preceding neutral face (i.e. happy-invalid trials) compared to the happy face (i.e. happy-valid trials). Importantly, this preferential spatial orienting to negative emotion was not observed in Experiment 3, where the goal relevance of emotion was high. However, in that experiment, fearful faces produced a specific attentional bias during the DPT, which was mostly driven by the induction trials themselves.

Digital health literacy and its determinants among community dwelling elderly people in Taiwan.

Background: Digital Health Literacy (DHL) is crucial in navigating digital health environments, yet few studies focus on older adults. Objective: Explore the associations of digital health information and resource utilization, IT-related social support, and barriers/enhancers to digital health service usage with DHL among older adults. Methods: A cross-sectional study was conducted from January 2022 to April 2023, involving 417 individuals over the age of 60 who were interviewed using an instrument for collecting data on DHL, social support, barriers/enhancers influencing use of digital health resources and personal/demographic data. Multi-regression models were used to examine the associations. Results: Higher DHL scores were associated with daily use of digital interaction with healthcare (B = 0.28; 95% confidence interval [CI] = 0.07, 0.49; p = .01), daily use of other digital health resources (B = 0.22; 95% CI = 0.05, 0.40; p = .01), ease in finding assistance for online navigation (B = 0.27; 95% CI = 0.08, 0.45; p = .01), self-perceived digital proficiency ("usually very good at surfing the internet," B = 0.35; 95% CI = 0.18, 0.52; p = .01), assistance from relatives/others in internet browsing (B = 0.20; 95% CI = 0.02, 0.37; p = .02), and having access to a computer, tablet, or smartphone (B = 0.29; 95% CI = 0.11, 0.47, p = .01). Conversely, barriers like "no access to a computer, tablet, or phone at all times" (B = -0.19; 95% CI = -0.34, -0.04; p = .01), "difficulty understanding online content" (B = -0.22; 95% CI = -0.36, -0.07; p = .01), and "believing to be too old for online services" (B = -0.18; 95% CI = -0.32, -0.03; p = .02) were associated with lower DHL scores. Conclusions: Engagement with digital health platforms, including making online appointments and accessing personal health records, is associated with higher DHL levels. Support from relatives or others, a modifiable attribute, is also associated with elevated DHL among older adults.

Grounding, necessity, and relevance.

Grounding necessitarianism (GN) is the view that full grounds necessitate what they ground. Although GN has been rather popular among philosophers, it faces important counterexamples: For instance, A = [Socrates died] fully grounds C = [Xanthippe became a widow]. However, A fails to necessitate C: A could have obtained together with B = [Socrates and Xanthippe were never married], without C obtaining. In many cases, the debate essentially reduces to whether A indeed fully grounds C-as the contingentist claims-or if instead C is fully grounded in A+, namely A plus some supplementary fact S (e.g. [Xanthippe was married to Socrates])-as the necessitarian claims. Both sides typically agree that A+ necessitates C, while A does not; they disagree on whether A or A+ fully grounds C. This paper offers a novel defence of the claim that, in these typical cases, unlike A+, A fails to fully ground C-thereby bringing further support to GN. First and foremost, unlike A+, A fails to fully ground C because it fails to contain just what is relevant to do so, in two distinct senses-explanatory and generative relevance. Second, going for A, rather than A+, as a full ground undermines not just grounding necessitarianism, but modally weaker views which even contingentists may want to preserve.

Endocrine disruption assessment in aquatic vertebrates - Identification of substance-induced thyroid-mediated effect patterns.

According to the World Health Organisation and European Commission definitions, substances shall be considered as having endocrine disrupting properties if they show adverse effects, have endocrine activity and the adverse effects are a consequence of the endocrine activity (using a weight-of-evidence approach based on biological plausibility), unless the adverse effects are not relevant to humans or non-target organisms at the (sub)population level. To date, there is no decision logic on how to establish endocrine disruption via the thyroid modality in non-mammalian vertebrates. This paper describes an evidence-based decision logic compliant with the integrated approach to testing and assessment (IATA) concept, to identify thyroid-mediated effect patterns in aquatic vertebrates using amphibians as relevant models for thyroid disruption assessment. The decision logic includes existing test guidelines and methods and proposes detailed considerations on how to select relevant assays and interpret the findings. If the mammalian dataset used as the starting point indicates no thyroid concern, the Xenopus Eleutheroembryonic Thyroid Assay allows checking out thyroid-mediated activity in non-mammalian vertebrates, whereas the Amphibian Metamorphosis Assay or its extended, fixed termination stage variant inform on both thyroid-mediated activity and potentially population-relevant adversity. In evaluating findings, the response patterns of all assay endpoints are considered, including the direction of changes. Thyroid-mediated effect patterns identified at the individual level in the amphibian tests are followed by mode-of-action and population relevance assessments. Finally, all data are considered in an overarching weight-of-evidence evaluation. The logic has been designed generically and can be adapted, e.g. to accommodate fish tests once available for thyroid disruption assessments. It also ensures that all scientifically relevant information is considered, and that animal testing is minimised. The proposed decision logic can be included in regulatory assessments to facilitate the conclusion on whether substances meet the endocrine disruptor definition for the thyroid modality in non-mammalian vertebrates.

Subtleties in Bayesian decision-theoretic analysis for forensic findings: Notes on recent discussion of the role of validation study data in rational decision making.

This technical note extends a recent discussion in this journal of the role of validation study data in rational decision making. One argument that has been made in this context, using elements of Bayesian decision theory, is that further aggregation of validation study data into error rates involves a loss of information that compromises rational inference and decision making and should therefore be discouraged. This technical note seeks to explain that this argument can be developed at different levels of detail, depending on the definition of the propositions of interest, the forensic findings to be evaluated (and hence the form of the likelihood ratio), and the characterization of the relative desirability of decision consequences. The analyses proposed here reveal the cascade of abstractions and assumptions into which discussions about the use of validation study results in forensic science have fallen. This reinforces the conclusion that further aggregation of validation study data into error rates is problematic. It also suggests that even if a definition of error rate(s) could be agreed upon and defensively quantified in a given application, we should rethink and possibly adjust our expectations about what exactly error rates can practically contribute to rational modes of reasoning and decision making in legal contexts.
