Associations and Potential Multiple Mechanisms between Subjective Hearing Loss and Cognitive Impairment.

BACKGROUND: Subjective hearing loss (SHL) refers to an individual's self-assessment of their hearing loss. The association and underlying mechanisms between SHL and cognitive impairment still necessitate elucidation. OBJECTIVES: To validate potential mechanisms between SHL and cognitive impairment. DESIGN: Cross-section. SETTING: Shanghai, China. PARTICIPANTS: A total of 2369 individuals from communities and the cognitive disorder clinic. MEASUREMENTS: All participants were subjected to a comprehensive neuropsychological assessment, encompassing the Hearing Handicap Inventory for the Elderly-Screening Version (HHIE-S). The participants' brain ß-amyloid (Aß) deposition status, plasma biomarkers associated with Alzheimer's disease (AD), and cardiovascular risk factors were also collected. RESULTS: In individuals with a heightened SHL, elevated HHIE-S score was linked to diminished cognitive and daily functioning as well as heightened levels of depressed mood. This correlation was observed in auditory memory performance but not in visual memory. The influence of SHL on cognitive function was mediated by depressed mood. SHL was associated with diabetes and smoking, whereas cognitive function was associated with hyperlipidemia and alcohol consumption. In individuals with positive brain Aß deposition, SHL demonstrated associations with cognitive function independent of plasma Aß42/40 ratio, P-tau181, neurofilament light chain, and APOE allele status. CONCLUSION: SHL has an independent effect on cognitive impairment. The findings do no provide evidence for the common cause mechanism. Instead, the findings support the presence of a cognitive resource mechanism and an impoverished environment mechanism, along with the potential for a pathological interaction mechanism.

Haemorrhoidal disease in pregnancy: results from a self-assessment questionnaire administered by means of a social network.

BACKGROUND: The anal symptoms occurring during pregnancy and post-partum, mainly related to Haemorrhoidal Disease (HD), have been reported with in a wide range of incidence in the literature. Although in many cases the course of the disease is mild and self-limiting, sometimes it is severe enough to affect quality of life. METHODS: Our study has been conducted through a questionnaire administered via social media with the aim of obtaining epidemiologic data on the incidence of the symptoms of HD in an unselected population of pregnant women. In addition, we looked for the presence of those factors notoriously predisposing or associated to HD (constipation, straining on the toilet, low dietary fibres and fluid intake). RESULTS: Out of 133 patients 51% reported symptoms of HD during pregnancy, mainly in the second and third trimester. Constipation, straining on the toilet, low dietary fibres and fluid intake were not significantly related to incidence of HD. Only a previous history of HD was correlated to onset of symptoms of HD in pregnancy and reached a statistical significance (odds ratio = 5.2, p < 0.001). CONCLUSION: Although with the limitations posed by the nature of our retrospective study via a self-assessment interview, our results suggest that the occurrence of HD in pregnancy seems not sustained by the classical risk factors observed in the general population. At the moment, specific therapeutic measures are lacking and treatment relies on empiric suggestions concerning diet, fluid intake, bowel care, local ointment. Further studies are needed in order to identify a targeted etiologic treatment.

Ethnic discrimination, asking for fair treatment, and poor self-rated health: a gender stratified analysis of 13,443 Korean Chinese waged workers in South Korea.

BACKGROUND: In South Korea, Korean Chinese workers experience ethnic discrimination although they share physical similarities and ethnic heritage with native-born Koreans. This study aimed to examine whether perceived ethnic discrimination is associated with poor self-rated health and whether the association differs by gender among Korean Chinese waged workers in South Korea. METHODS: We conducted a pooled cross-sectional analysis using data of 13,443 Korean Chinese waged workers from the Survey on Immigrants' Living Conditions and Labor Force conducted in 2018, 2020, and 2022. Based on perceived ethnic discrimination, asking for fair treatment, and subsequent situational improvement, respondents were classified into the following four groups: "Not experienced," "Experienced, not asked for fair treatment," "Experienced, asked for fair treatment, not improved," and "Experienced, asked for fair treatment, improved." Poor self-rated health was assessed using a single question "How is your current overall health?" We applied logistic regression to examine the association between perceived ethnic discrimination and poor self-rated health, with gender-stratified analyses. RESULTS: We found an association between ethnic discrimination and poor self-rated health among Korean Chinese waged workers. In the gender-stratified analysis, the "Experienced, not asked for fair treatment" group was more likely to report poor self-rated health compared to the "Not experienced" group, regardless of gender. However, gender differences were observed in the group stratified by situational improvements. For male workers, no statistically significant association was found in the "Experienced, asked for fair treatment, improved" group with poor self-rated health (odd ratios: 0.87, 95% confidence intervals: 0.30-2.53). Conversely, among female workers, a statistically significant association was observed (odd ratios: 2.63, 95% confidence intervals: 1.29-5.38). CONCLUSIONS: This study is the first to find an association between perceived ethnic discrimination and poor self-rated health, along with gender differences in the association between situational improvements after asking for fair treatment and poor self-rated health among Korean Chinese waged workers in South Korea.

Association of healthy eating index and self-rated health in adults living in Tehran: a cross-sectional study.

BACKGROUND: Self-rated health (SRH) has been identified in many studies as a valid predictor of mortality and healthcare utilization. There is limited research on SRH and dietary intake. This study aimed to investigate the association between healthy eating index (HEI) and SRH in adults living in Tehran. METHODS: This cross-sectional study was carried out among 850 adult men and women aged 20-59 years who visited health centers in Tehran from 2021 to 2022. Dietary intake was assessed using a validated and reliable semiquantitative food frequency questionnaire with 168 food items, and SRH was assessed with one question: "In general, how do you rate your health?". We categorized SRH into excellent/very good, good, and fair/poor. In the descriptive statistics part, we used mean ± standard deviation or number (ratio) for quantitative and qualitative variables, respectively. The chi-squared test and one-way analysis of variance were used to calculate the percentage and mean for demographic characteristics across tertiles of SRH. An analysis of covariance was used to compare the means of energy, macronutrients, the HEI, and its component variables across the tertiles of SRH. RESULTS: The final sample included 795 participants (68.2% female; mean ± standard deviation age: 44.81 ± 10.62 years) whose 40% reported excellent/very good SRH, and 30% reported good and fair/poor SRH separately. There was no association between body mass index, physical activity, education, health status, smoking, and sleep duration with SRH. After adjustment, the total HEI score and its component scores did not differ across the tertiles of SRH status. However, participants with good SRH had a higher intake of total energy (mean difference (MD): 180.33 Kcal, P value < 0.001), total fat (MD: 8.15 gr, P value = 0.002), and total carbohydrates (MD: 20.18 gr, P value = 0.004) than those with fair/poor SRH. CONCLUSION: According to our findings, fair/poor SRH was associated with a lower consumption of total energy, total fat, and total carbohydrates in Iranian adults. Additional observational studies would be necessary to clarify these findings.

The effect of sleep problems on core self-evaluations in undergraduate nursing students and the role of emotion regulation and resilience: A cross-sectional study.

BACKGROUND: Nursing students are prone to sleep problems that affect their core self-evaluations. However, little attention has been paid to the specific roles of emotion regulation (including cognitive reappraisal and expressive suppression) and resilience in this process. OBJECTIVES: This study aimed to explore 1) the direct effect of sleep problems on core self-evaluations among nursing students; 2) the chain-mediating effect of cognitive reappraisal and resilience on the relationship between sleep problems and core self-evaluations; 3) the moderating effect of expressive suppression on the direct relationship between sleep problems and core self-evaluations; and 4) the moderating effect of expressive suppression on the indirect relationship between sleep problems affecting core self-evaluations through resilience. METHODS: A total of 345 nursing students completed a survey conducted between September and October 2022. Data was analyzed using descriptive analysis, Fisher exact test, Kruskal-Wallis H test, Spearman correlation analysis, and hierarchical regression analysis. Additionally, the SPSS PROCESS V4.0 plug-in was used to verify the moderated chain-mediating effect. RESULTS: Sleep problems directly affected core self-evaluations among nursing students. Cognitive reappraisal and resilience played a partial chain-mediating role in the relationship between sleep problems and core self-evaluations, with expressive suppression having a direct moderating effect. CONCLUSIONS: Opportunities exist for enhancing the core self-evaluations of nursing students by addressing their sleep problems, promoting cognitive reappraisal strategies, and increasing resilience. Additionally, encouraging expressive suppression can mitigate the negative impact of sleep problems on nursing students' core self-evaluations.

School-aged children's movement behaviours and subjective health complaints in Japan: a cross-sectional study during COVID-19 pandemic-related school closures and after school reopenings.

BACKGROUND: Social restrictions associated with the COVID-19 pandemic have altered children's movement behaviours and impacted their mental health. However, the influence of social restrictions on subjective health complaints remains inadequately understood. This study compared adherence to 24-hour movement behaviour guidelines and the prevalence of subjective health complaints during school closure and one year after reopening. We also examined how combinations of adherence to movement behaviour recommendations relate to subjective health complaints. METHODS: A repeated cross-sectional survey was conducted at two points. The first survey in May 2020 included 1535 (766 boys and 769 girls) participants during school closures, while the second survey from May to July 2021 involved 1125 (583 boys and 542 girls) participants one year after school reopening. The questionnaire covered socio-demographics, physical activity, screen time, sleep, and subjective health complaints. Differences between periods were analysed using chi-square tests. Logistic regression models assessed the association between adherence to guidelines and subjective health complaints. RESULTS: During school closure, children were more likely to meet 'only sleep' recommendations and have irritability and lethargy symptoms. Irrespective of sex, those adhering to two or all three recommendations (excluding physical activity and screen time) had a lower risk of symptoms related to physical and mental pain, fatigue, irritability, and lethargy as compared to those who met none of the recommendations. CONCLUSIONS: Children should meet at least one physical activity or screen time recommendation in addition to sleep recommendations for subjective health. Strategies considering the priority of each movement behaviour are crucial, even during abnormal situations, such as pandemic-related social restrictions. This study offers insightful findings concerning children's mental health issues during unprecedented and massive disasters or crises.

Unlocking employee innovative behavior: the role of humble leadership, core self-evaluation, and leader-member exchange.

Humble leadership has gained attention in recent years due to its potential impact on employee performance. This study explores the association between humble leadership and follower innovative behavior by investigating the moderating role of core self-evaluation (CSE) and the mediating role of leader-member exchange (LMX). The study uses data from 328 followers and their immediate leaders to test a mediated moderation model. Results show that there is a favorable association between humble leadership and LMX and followers' innovative behavior, particularly pronounced for followers who possess lower levels of CSE. The findings suggest that humble leaders should focus their development efforts on followers with low CSE to achieve complementarity congruity and improved innovation. This research enhances the existing body of knowledge by emphasizing the significance of comprehending the functions of relational procedures and the psychological resources of followers in determining the effectiveness of humble leadership. These findings have practical implications for organizations seeking to enhance their leadership effectiveness and followers' innovative behavior.

Overlapping yet dissociable contributions of superiority illusion features to Ponzo illusion strength and metacognitive performance.

Humans are typically inept at evaluating their abilities and predispositions. People dismiss such a lack of metacognitive insight into their capacities while even enhancing (albeit illusorily) self-evaluation such that they should have more desirable traits than an average peer. This superiority illusion helps maintain a healthy mental state. However, the scope and range of its influence on broader human behavior, especially perceptual tasks, remain elusive. As belief shapes the way people perceive and recognize, the illusory self-superiority belief potentially regulates our perceptual and metacognitive performance. In this study, we used hierarchical Bayesian estimation and machine learning of signal detection theoretic measures to understand how the superiority illusion influences visual perception and metacognition for the Ponzo illusion. Our results demonstrated that the superiority illusion correlated with the Ponzo illusion magnitude and metacognitive performance. Next, we combined principal component analysis and cross-validated regularized regression (relaxed elastic net) to identify which superiority components contributed to the correlations. We revealed that the "extraversion" superiority dimension tapped into the Ponzo illusion magnitude and metacognitive ability. In contrast, the "honesty-humility" and "neuroticism" dimensions only predicted Ponzo illusion magnitude and metacognitive ability, respectively. These results suggest common and distinct influences of superiority features on perceptual sensitivity and metacognition. Our findings contribute to the accumulating body of evidence indicating that the leverage of superiority illusion is far-reaching, even to visual perception.

Self-rated health in old age, related factors and survival: A 20-Year longitudinal study within the Silver-MONICA cohort.

INTRODUCTION: Self-rated health (SRH) offers insights into the evolving health demographics of an ageing population. AIM: To assess change in SRH from old age to very old age and their associations with health and well-being factors, and to investigate the association between SRH and survival. METHODS: All participants in the MONICA 1999 re-examination born before 1940 (n = 1595) were included in the Silver-MONICA baseline cohort. The Silver-MONICA follow-up started in 2016 included participants in the Silver-MONICA baseline cohort aged 80 years or older. Data on SRH was available for 1561 participants at baseline with 446 of them also participating in the follow-up. The follow-up examination included a wide variety of measurements and tests. FINDINGS: Most participants rated their health as "Quite good" (54.5 %) at baseline. Over the study period, 42.6 % had stable SRH, 40.6 % had declined, and 16.8 % had improved. Changes in SRH were at follow-up significantly associated with age, pain, nutrition, cognition, walking aid use, self-paced gait speed, lower extremity strength, independence in activities of daily living, weekly physical exercise, outdoor activity, participation in organized activities, visiting others, morale, and depressive symptoms. SRH at baseline was significantly associated with survival (p < 0.05). CONCLUSION: This study demonstrates associations between changes in SRH and a multitude of health- and wellbeing-related factors, as well as a relation between survival and SRH, accentuating their relevance within the ageing population.

[Social security disability assessments: validity tests are useful]. / Verzekeringsgeneeskundige oordeelsvorming.

Social security disability assessors are required to objectively quantify disability with regards to potential ability to work. Difficulties arise when assessments need to be performed in the absence of objective medical data relying solely on self-report regarding subjective health complaints. In such cases, validity tests provide a useful tool during an assessment. This case report illustrates this through the outcomes of 3 disability assessments.

A newly detected bias in self-evaluation.

The widely observed positive bias on self-evaluation is mainly explained by the self-enhancement motivation which minimizes negative feedbacks and emphasizes positive ones. Recent agent based simulations suggest that a positive bias also emerges if the sensitivity to feedbacks decreases when the self-evaluation increases. This paper proposes a simple mathematical model in which these different biases are integrated. Moreover, it describes an experiment (N = 1509) confirming that the sensitivity to feedbacks tends to decrease when self-evaluation increases and that a directly related positive bias is detected.

Emotional labor and burnout among nurses in Iran: core self-evaluations as mediator and moderator.

BACKGROUND: This study investigated the mediating and moderating impact of core self-evaluations in the path from emotional labor to burnout. Our hypothesized associations are based on Hobfoll (Rev Gen Psychol 6:307-24, 2002) conservation of resources theory. METHOD: Three hundred nurses from four hospitals in Abadan, Iran, were invited to participate in our study. Of the 300, 255 completed all sections and questions in our survey for an 85% response rate. The posited direct and indirect effects were evaluated with structural equation modeling and the interaction effects were evaluated with hierarchical moderated regression and simple regression slope plots. RESULT: Deep acting has indirect effects on burnout through core self-evaluations. Though unrelated to surface acting, core self-evaluations moderate its impact: under low core self-evaluations, surface acting is strongly related to emotional exhaustion and inversely related to personal accomplishment, whereas, under high core self-evaluations, surface acting is unrelated to these burnout dimensions. CONCLUSION: Our findings reveal the dual functions of CSE as a psychological resource and buffer to offset the interpersonal demands of patient care. Limitations, directions for future research, and practical implications are discussed.

Discrepancies between self- and informant-ratings of functional abilities and objective cognition: predictors of bias in mild cognitive impairment.

OBJECTIVE: Self- and informant-ratings of functional abilities are used to diagnose mild cognitive impairment (MCI) and are commonly measured in clinical trials. Ratings are assumed to be accurate, yet they are subject to biases. Biases in self-ratings have been found in individuals with dementia who are older and more depressed and in caregivers with higher distress, burden, and education. This study aimed to extend prior findings using an objective approach to identify determinants of bias in ratings. METHOD: Participants were 118 individuals with MCI and their informants. Three discrepancy variables were generated including the discrepancies between (1) self- and informant-rated functional status, (2) informant-rated functional status and objective cognition (in those with MCI), and (3) self-rated functional status and objective cognition. These variables served as dependent variables in forward linear regression models, with demographics, stress, burden, depression, and self-efficacy as predictors. RESULTS: Informants with higher stress rated individuals with MCI as having worse functional abilities relative to objective cognition. Individuals with MCI with worse self-efficacy rated their functional abilities as being worse compared to objective cognition. Informant-ratings were worse than self-ratings for informants with higher stress and individuals with MCI with higher self-efficacy. CONCLUSION: This study highlights biases in subjective ratings of functional abilities in MCI. The risk for relative underreporting of functional abilities by individuals with higher stress levels aligns with previous research. Bias in individuals with MCI with higher self-efficacy may be due to anosognosia. Findings have implications for the use of subjective ratings for diagnostic purposes and as outcome measures.

The Association Between Family Support and Changes in Self-Rated Health Among Chinese Older Adults: How Living Arrangements Moderate the Association?

OBJECTIVES: The study intends to investigate the association between family support and older adult health as well as the interaction between family support and living arrangements on their health. DESIGN: Cross-sectional study. SETTING AND PARTICIPANTS: Samples included in the final analysis (N = 11,430) come from the 2018 Chinese Longitudinal Healthy Longevity Survey (CLHLS). METHODS: Multiple logistic regression analysis was used to analyze the associations between family supports, multiplicative interaction of family supports and living arrangements, and self-rated health change. Subgroup analysis on disabled older adults was supplemented. RESULTS: Older adult individuals who received functional support, provided financial support, and had frequent emotional communication with their children in the past year reported better self-rated health. Moreover, having frequent emotional communication with children could bring better self-rated health for the older adults living with spouses and children (ORbetter vs same = 2.765, P < .01) and empty nesters who lived without children (ORbetter vs same = 1.551, P < .05). CONCLUSIONS AND IMPLICATIONS: Our findings imply that functional support and emotional support may play an increasingly important role in the health of Chinese older individuals. The interaction between emotional support and 2 living arrangements mentioned above is relevant to better health of older individuals. We advocate for culturally tailored Age-Friendly Communities augmenting the geriatric health care framework. While bolstering social support for seniors, prioritizing fundamental needs is paramount for those with disabilities.

Grammar enhancement in EFL instruction: a reflection on the effects of self-evaluation, teacher support, and L2 grit.

Advancement in learning grammar and using it practically is one of the challenges of English as foreign learners (EFL) learners. Its progression may be expedited or slowed down by a variety of causes. Among the crucial factors, the possible effects of self-evaluation, teacher support, and L2 grit were still untouched which is the target of the current research. In so doing, 86 EFL students at the intermediate level were divided into two groups (i.e., experimental group and control group). The students in the control group (CG) are exposed to normal education, whereas learners in experimental group (EG) get extra instruction to practice self-evaluation and L2 Grit. Moreover, the emphasis on the teacher's position as a facilitator and supporter was more prominent in the EG. Based on data screening which was completed via one-way ANCOVA, learners in EG were more successful in grammar assessment due to the treatment. Further research avenues and educational implications were elaborated upon.

Bedtime negative affect, sleep quality and subjective health in rural China.

BACKGROUND: The overall level of negative affect (NeA) has been linked to impaired health. However, whether the diurnal timing of NeA matters and whether the NeA-health relationship is mediated by sleep quality remain unclear. METHODS: Using a longitudinal dataset (2006, 2009 and 2014 waves) consisting of 1959 participants, we examined the within-person impact of both bedtime NeA and non-bedtime NeA measured by Day Reconstruction Method (DRM) on subjective health measured by Visual Analogue Scale (VAS), and the mediating effect of sleep quality on the NeA-health relationships by fixed effect models. RESULTS: Bedtime NeA predicted poorer health, while non-bedtime NeA was unrelated to health. The deleterious impact of bedtime NeA reduced and became non-significant after sleep quality was controlled for. Bedtime NeA also significantly predicted impaired sleep quality. CONCLUSIONS: Bedtime NeA is a stronger predictor of poorer health than non-bedtime NeA, and the deleterious influence of bedtime NeA on health seems to operate through poor sleep quality. Therefore, interventions to reduce bedtime NeA could potentially improve subsequent sleep quality, thereby protecting people to some extent from impaired health status.

Temporal self-appraisals associated with suicide-related thoughts and behaviors.

BACKGROUND: Temporal self-appraisal (TSA) is the trajectory of self-appraisal over time, including how a person views their past and future selves in relation to their present self. In this study, we examined the TSA of individuals with and without a history of suicide-related thoughts and behaviors (STBs). METHODS: Using Amazon Mechanical Turk for recruitment, we studied 397 participants on validated measures of TSA, STBs, and mood. RESULTS: The non-STB group (n = 291) had a TSA trajectory similar to that previously found for nonclinical populations, with perceived self-improvement over time. In contrast, the TSA of the STB group (n = 106) had two distinct qualities: their TSA profiles were more negative at all time points (past, present, and future) than the non-STB group, and they displayed similar anticipated present-to-future growth as the non-STB group but perceived minimal past-to-present change. These differences persisted when controlling for depression, anxiety, and stress, suggesting a distinct STB-related TSA profile independent of comorbid affective states. LIMITATIONS: This study is limited by the use of self-report measures and cross-sectional design. CONCLUSIONS: By investigating TSA, this study provides insights into the unique aspects of self-appraisal associated with having a history of STBs and emphasizes the need for therapeutic interventions that foster self-continuity and positive self-appraisal across time. Future research should focus on clarifying the mechanisms underlying this distinct self-appraisal pattern in the STB group and the effects of interventions that enhance temporal self-appraisal.

A Novel Indicator to Correct for Individual Reported Heterogeneity. An Application to Self-Evaluation of Later-Life Depression.

Program evaluations often investigate complex or multi-dimensional constructs, such as individual opinions or attitudes, by means of ratings. A different interpretation of the same question may affect cross-country comparability, leading to the Differential Item Functioning problem. Anchoring vignettes were introduced in the literature as a way to adjust self-evaluations from this interpersonal incomparability. In this paper, we first introduce a new nonparametric solution to analyse anchoring vignette data, recoding a variable based on a rating scale to a new corrected-variable that guarantees comparability in any cross-country analysis. Then, we exploit the flexibility of a mixture model introduced to account for uncertainty in the response process (the CUP model) to test if the proposed solution is effectively able to remove this reported heterogeneity. This solution is easy to construct and has important advantages compared with the original nonparametric solution adopted with anchoring vignette data. The novel indicator is applied to investigate self-reported depression in an old population. Data that will be analysed come from the second wave of the Survey of Health, Ageing and Retirement in Europe, collected in 2006/2007. Results highlight the need of correcting for reported heterogeneity comparing individual self-evaluations. Once interpersonal incomparability resulting from the different uses of response scales is removed from the self-assessments, some estimates are reversed in magnitude and signs with respect to the analysis of the collected data.

Children's self-evaluation of their prosociality when comparing themselves with a specific versus abstract other.

This study examines the development of children's self-assessment of their prosociality in normative social comparisons with an average peer, who was either a concrete individual, or an abstract one, at a school of average socioeconomic level in south Israel (N = 148, Age 6-12 years, 51% females; June 2021). Results show that older children exhibited the better-than-average (BTA) effect by perceiving themselves as more generous than their average peer. Conversely, younger children exhibited a worse-than-average effect, in that they assumed that their peers would act more generously than themselves ( η p 2 = .23 ). Only the older children (aged 8 years onward) were significantly affected by the concreteness of the target of comparison by exhibiting the BTA effect only when the average peer was abstract (not concrete).
