Dominance analysis to assess solute contributions to multicomponent phase equilibria.

Phase separation in aqueous solutions of macromolecules underlies the generation of biomolecular condensates in cells. Condensates are membraneless bodies, representing dense, macromolecule-rich phases that coexist with the dilute, macromolecule-deficient phases. In cells, condensates comprise hundreds of different macromolecular and small molecule solutes. How do different solutes contribute to the driving forces for phase separation? To answer this question, we introduce a formalism we term energy dominance analysis. This approach rests on analysis of shapes of the dilute phase boundaries, slopes of tie lines, and changes to dilute phase concentrations in response to perturbations of concentrations of different solutes. The framework is based solely on conditions for phase equilibria in systems with arbitrary numbers of macromolecules and solution components. Its practical application relies on being able to measure dilute phase concentrations of the components of interest. The dominance framework is both theoretically facile and experimentally applicable. We present the formalism that underlies dominance analysis and establish its accuracy and flexibility by deploying it to analyze phase diagrams probed in simulations and in experiments.

Oral Health Differences Between Middle-Aged and Older Adults in South Korea.

INTRODUCTION AND AIMS: The oral health characteristics of middle-aged and older adults exhibit variations. This study identifies the various factors associated with oral health among middle-aged and older adults through a subgroup analysis by age group of data representative of the South Korean population. METHODS: We examined influencing factors: demographic, socioeconomic, dental, physical attributes, psychological, and mental attributes. Oral health was assessed using the Geriatric Oral Health Assessment Index. The participants were divided into two groups: those under 65 years of age (middle-aged) and those over 65 years of age (older adults). We used multiple linear regression analysis and dominance analysis to determine the dominant factors associated with oral health. RESULTS: A total of 6369 participants were aged 69.2 ± 9.8 years on average, and 57.5% were women. Dominance analysis revealed that lower educational levels and activity difficulty caused by diseases were significantly associated with both groups. Moreover, depressive symptoms were the foremost adverse factor linked to oral health in the middle-aged (P < .001, standardized beta [ß] = -4.30, general dominance index [GDI] = 19.00) and older (P < .001, ß = -0.30, GDI = 10.70) adults. The number of teeth exhibited the most positive association with oral health in both middle-aged (P < .001, ß = 0.20, GDI = 5.30) and older (P < .001, ß = 0.23, GDI = 7.40) adults. However, cognitive function, dental visits, body mass index, severe pain, functional limitations, and cognitive function exhibited distinct patterns between the age groups. CONCLUSION: Depressive symptoms and the number of teeth significantly influence oral health in middle-aged and older adults, though the impact varies by age. These findings stress the importance of tailored strategies considering age-specific attributes for effective oral health improvement. CLINICAL RELEVANCE: Enhancing oral health requires healthcare providers to prioritize monitoring age-specific risk factors. Further, educational plans should highlight the importance of preventive oral care and regular dental visits.

Dominance Analysis for Latent Variable Models: A Comparison of Methods With Categorical Indicators and Misspecified Models.

Dominance analysis (DA) is a very useful tool for ordering independent variables in a regression model based on their relative importance in explaining variance in the dependent variable. This approach, which was originally described by Budescu, has recently been extended to use with structural equation models examining relationships among latent variables. Research demonstrated that this approach yields accurate results for latent variable models involving normally distributed indicator variables and correctly specified models. The purpose of the current simulation study was to compare the use of this DA approach to a method based on observed regression DA and DA when the latent variable model is estimated using two-stage least squares for latent variable models with categorical indicators and/or model misspecification. Results indicated that the DA approach for latent variable models can provide accurate ordering of the variables and correct hypothesis selection when indicators are categorical and models are misspecified. A discussion of implications from this study is provided.

The association of comorbidities with sleep quality among Australians with multiple sclerosis: Insights from the Australian Multiple Sclerosis Longitudinal Study.

BACKGROUND: Comorbidities and poor sleep quality are prevalent among individuals with multiple sclerosis (MS). Our understanding of the effects of comorbidities on sleep quality in MS remains limited. OBJECTIVES: The objectives were to investigate whether the number and presence of specific comorbidities have associations with sleep quality and to assess the relative contribution of comorbidity groups to sleep quality. METHODS: We collected data on sleep quality (using Pittsburgh Sleep Quality Index (PSQI)) and presence of comorbidities in people with MS (n = 1597). Associations between comorbidities and sleep quality were examined using linear regression and dominance analysis. RESULTS: Having more comorbidities was associated with poorer sleep quality (p for trend < 0.001). All 13 groups of comorbidities explained 12.9% of the variance in PSQI from which half of the variance was contributed by mental health disorders. In total, 16 of the 28 comorbidities were associated with significantly worse sleep quality, with the strongest associations seen for 'other autoimmune diseases' (ß = 1.98), depression (ß = 1.76), anxiety (ß = 1.72) and rheumatoid arthritis (ß = 1.62). CONCLUSIONS: Many individual comorbidities are associated with poorer sleep quality, with mental health disorders making the largest relative contribution. Optimal management of comorbidities that make the greatest contributions could have the largest benefit for improving sleep in MS.

24-Hour Urinary Chemistries and Kidney Stone Risk.

RATIONALE & OBJECTIVE: Most previous studies of the relationship between urinary factors and kidney stone risk have either assumed a linear effect of urinary parameters on kidney stone risk or implemented arbitrary thresholds suggesting biologically implausible "all-or-nothing" effects. In addition, little is known about the hierarchy of effects of urinary factors on kidney stone risk. This study evaluated the independent associations between urine chemistries and kidney stone formation and examined their magnitude and shape. STUDY DESIGN: Prospective cohort study. SETTING & PARTICIPANTS: We analyzed 9,045 24-hour urine collections from 6,217 participants of the Health Professionals Follow-Up Study and Nurses' Health Studies I and II. EXPOSURE: Urine volume and pH, and concentrations of calcium, citrate, oxalate, potassium, magnesium, uric acid, phosphorus, and sodium. OUTCOME: Incident symptomatic kidney stones. ANALYTICAL APPROACH: Multivariable logistic regression analysis incorporating restricted cubic splines to explore potentially nonlinear relationships between urinary factors and the risk of forming a kidney stone. Optimal inflection point analysis was implemented for each factor, and dominance analysis was performed to establish the relative importance of each urinary factor. RESULTS: Each urinary factor was significantly associated with stone formation except for urine pH. Higher urinary levels of calcium, oxalate, phosphorus, and sodium were associated with a higher risk of stone formation whereas higher urine volume, uric acid, citrate, potassium, and magnesium were associated with a lower risk. The relationships were substantially linear for urine calcium, uric acid, and sodium. By contrast, the magnitudes of the relationships were modestly attenuated at levels above the inflection points for urine oxalate, citrate, volume, phosphorus, potassium, and magnesium. Dominance analysis identified 3 categories of factors' relative importance: higher (calcium, volume, and citrate), intermediate (oxalate, potassium, and magnesium), and lower (uric acid, phosphorus, and sodium). LIMITATIONS: Predominantly White participants, lack of information on stone composition. CONCLUSIONS: Urine chemistries have complex relationships and differential relative associations with the risk of kidney stone formation. PLAIN-LANGUAGE SUMMARY: Kidney stones are common and likely to recur. Certain urinary factors play a role in the development of stones, but their independent roles, relative importance, and shapes of association with stone formation are not well-characterized. We analyzed 24-hour urine collections from individuals with and without kidney stones. Stones were less likely in those with higher urine volume, citrate, potassium, magnesium, and uric acid and were more likely in those with higher calcium, oxalate, phosphorus, and sodium. The acidity of the urine was not related to stones. The urinary parameters showed different degrees of relative importance, with calcium, volume, and citrate being greatest. All parameters exhibited a linear or close-to-linear shape of association with stone formation.

The Sensitivity to Pain Traumatization Scale-Child Version (SPTS-C): Development and preliminary validation.

Background: Sensitivity to pain traumatization is defined as the propensity to develop cognitive, affective, and behavioral responses to pain that resemble a traumatic stress reaction. To date, sensitivity to pain traumatization has been assessed in adults (Sensitivity to Pain Traumatization Scale [SPTS-12]) and parents of youth with chronic pain (Sensitivity to Pain Traumatization Scale-Parent version [SPTS-P]). SPT may be relevant in the context of pediatric chronic pain given the substantial comorbidity between posttraumatic stress symptoms and pain. Aims: This prospective study aimed to adapt the SPTS-12 for use in youth and to evaluate the psychometric properties of the new scale. Methods: Participants included 175 youth with chronic pain (Mage = 14.31 years, 73% girls) referred to outpatient chronic pain programs. At baseline, youth self-reported the levels of their sensitivity to pain traumatization (Sensitivity to Pain Traumatization Scale-Child version [SPTS-C]), as well as their pain symptoms, pain-related anxiety, posttraumatic stress symptoms, and attentional control. Three months later, youth self-reported their pain symptoms and completed the SPTS-C. Results: The SPTS-C had a one-factor structure that explained 48% of variance and demonstrated good reliability and construct validity. SPTS-C baseline scores predicted follow-up levels of pain interference but not pain intensity or pain unpleasantness. Conclusions: The results provide preliminary evidence for the psychometric properties of the SPTS-C and the potential role of SPT in pediatric chronic pain outcomes.

Contexte: La sensibilité à la traumatisation de la douleur est définie comme la propension à développer des réponses cognitives, affectives et comportementales à la douleur qui ressemblent à une réaction de stress traumatique. À ce jour, la sensibilité à la traumatisation de la douleur a été évaluée chez les adultes (Échelle de sensibilité à la traumatisation de la douleur [SPTS-12]) et chez les parents de jeunes souffrant de douleur chronique (Échelle de sensibilité à la traumatisation de la douleur - Version parent [SPTS-P]). La sensibilité à la traumatisation de la douleur peut être pertinente dans le contexte de la douleur chronique pédiatrique étant donné la comorbidité importante entre les symptômes de stress post-traumatique et la douleur.Objectifs: Cette étude prospective visait à adapter le SPTS-12 pour une utilisation chez les jeunes et à évaluer les propriétés psychométriques de la nouvelle échelle.Méthodes: Les participants comprenaient 175 jeunes souffrant de douleur chronique (âge M = 14,31 ans, 73 % de filles) référés aux programmes de traitement ambulatoire de la douleur chronique. Au départ, les jeunes ont autodéclaré les niveaux de leur sensibilité à la traumatisation de la douleur (Échelle de sensibilité à la traumatisation de la douleur - version enfant [SPTS-C]), ainsi que leurs symptômes de douleur, leur anxiété liée à la douleur, leurs symptômes de stress post-traumatique et leur contrôle attentionnel. Trois mois plus tard, les jeunes ont autodéclaré leurs symptômes de douleur et ont répondu au SPTS-C.Résultats: Le SPTS-C avait une structure à un facteur qui expliquait 48 % de la variance et démontrait une bonne fiabilité ainsi qu'une bonne validité de la construction. Les scores obtenus au SPTS-C au départ prédisaient les niveaux d'interférence de la douleur au suivi mais pas l'intensité de la douleur ou le désagrément de la douleur.Conclusions: Les résultats présentent des preuves préliminaires des propriétés psychométriques du SPTSC et le rôle potentiel de la sensibilité à la traumatisation de la douleur dans les résultats liés à la douleur chronique pédiatrique.

Dominance Analysis of Bright and Dark Dispositional Predictors of Socially Desirable Responding.

Although the role of so-called dark traits in the prediction of maladaptive behavior has seen a large increase in interest by researchers, the Big Five still maintain their ubiquity in the prediction of most behaviors. This study uses measures of the Dark Tetrad and the Big Five personality traits to predict a very specific form of maladaptive behavior: the impression management form of socially desirable responding. In regression-based dominance analysis, results suggest that not all of the Big Five nor the Dark Tetrad provide statistically significant incremental validity but as a block, the Big Five dominate the Dark Tetrad in the prediction of the purposeful misrepresentation of one's self to others on self-report inventories. More specifically, four of the Big Five as well as the traits of Machiavellianism and sadism from the Dark Tetrad are significant predictors of impression management.

Psychosomatic mechanisms of heart failure symptoms on quality of life in patients with chronic heart failure: A multi-centre cross-sectional study.

AIMS: To determine the contributions of different kinds of symptoms to the quality of life and mediating effect of psychological and physical symptoms between heart failure symptoms and quality of life. DESIGN: A multi-centre cross-sectional study. METHODS: 2006 chronic heart failure patients from four cities were recruited in China from January 2021 to December 2022. Patients' symptoms and quality of life were self-reported, and data were analysed using correlation analysis, dominance analysis and mediating effects analysis. RESULTS: The dominance analysis revealed that the overall mean contributions of heart failure, psychological and physical symptoms were .083, .085 and .111; 29.5%, 30.2% and 39.5% of the known variance. And heart failure symptoms could negatively affect quality of life through psychological and physical symptoms, accounting for 28.39% and 22.95% of the total effect. Heart failure symptoms could also affect quality of life through the chain-mediated effect of physical and psychological symptoms, accounting for 16.74%. CONCLUSIONS: Physiological symptoms had the strongest effect on quality of life and heart failure symptoms had the weakest. Most of the effect for heart failure symptoms on quality of life in chronic heart failure patients was mediated by psychological and physiological symptoms. RELEVANCE TO CLINICAL PRACTICE: It is important to design non-pharmacological intervention plans for the enhancement of physical and psychological symptoms' management skills, to reduce the adverse impact of heart failure symptoms on quality of life. REPORTING METHOD: Study methods and results reported in adherence to the STROBE checklist. NO PATIENT OR PUBLIC CONTRIBUTION: No patients or members of the public were involved in the study.

The Relative Importance of Psychopathy Features as Predictors of Externalizing Behaviors in Youth: A Multimethod Examination.

Research in youth psychopathy has focused heavily on the affective features (i.e., callous-unemotional [CU] traits) given robust links to severe and chronic forms of externalizing behaviors. Recently, there have been calls to expand the scope of work in this area to examine the importance of other interpersonal (i.e., antagonism) and behavioral (i.e., disinhibition) features of psychopathy. In the present study, we apply an under-utilized statistical approach (i.e., dominance analysis) to assess the relative importance of CU traits, antagonism, and disinhibition in the prediction of externalizing behaviors in youth, cross-sectionally and at 9-month follow-up. Using a multi-informant (youth- and parent-report), multi-method (questionnaire, ecological momentary assessment [EMA]) preregistered approach in a diverse sample of clinically referred youth (Mage = 12.60 years, SD = .95 years, 47% female; 61% racial/ethnic minority), we found youth- and parent-reported psychopathy features accounted for a significant proportion of variance in externalizing behavior cross-sectionally and longitudinally. However, results provided limited support for our preregistered hypotheses. While antagonism and disinhibition had larger general dominance weights relative to CU traits for both youth- and parent-report, most differences were non-significant. Thus, the interpersonal, affective, and behavioral psychopathy features could not be distinguished from one another in terms of their importance in the prediction of externalizing behavior, assessed cross-sectionally or longitudinally. Taken together, the results highlight promising avenues for future research on the relative importance of youth psychopathy features.

The association between different sources of distraction and symptoms of attention deficit hyperactivity disorder.

Introduction: Adults with Attention-Deficit/Hyperactivity Disorder (ADHD) are generally distractible. Yet, the precise relationship between ADHD and distractibility remains under-specified in two respects. First, different sources of distraction, such as background noise or mind wandering, may not be equally associated with ADHD. Second, ADHD itself comprises a variety of symptoms that show considerable heterogeneity and it is unclear which ADHD symptoms are associated with which type of distraction. Methods: The current study addresses these questions using one clinically evaluated sample (N = 69) and two large non-clinically evaluated samples (N = 569, N = 651). In all samples, participants completed questionnaires about their susceptibility to external distraction, unwanted intrusive thoughts, spontaneous mind-wandering and ADHD symptomatology. Results: Traditional regression and novel network analyses revealed an overwhelming contribution of spontaneous mind-wandering in explaining ADHD symptoms, although external distraction and unwanted intrusive thoughts were also associated with a small number of ADHD symptoms. Discussion: Findings support a growing body of literature linking spontaneous mind-wandering and ADHD, and they highlight the heterogeneity in the association between ADHD symptoms and different sources of distraction.

Do education and living standard matter in breaking barriers to healthcare access among women in Bangladesh?

BACKGROUND: Barriers to healthcare access for women have a substantial influence on maternal and child health. By removing barriers to accessing healthcare, several sustainable development goals can be achieved. The goal of this study, based on the dominance analysis, was to examine how living standards and spousal education play role in removing barriers to healthcare access for women in Bangladesh. METHODS: The study used the nationally representative Bangladesh Demographic and Health Survey (BDHS), 2017-18 data. A binary logistic regression model was applied for analyzing different types of health access barriers in the study. Additionally, a dominance analysis was conducted to identify the most responsible factors for removing barriers. RESULTS: In Bangladesh, 66% of women faced at least one barrier in accessing healthcare. The results obtained from logistic regression and dominance analysis revealed that women's standard of living and spousal education explained the highest variation of having at least one barrier in accessing healthcare. Specifically, a high standard of living explained 24% of the total explained variation (OR 0.56, 95% CI 0.52-0.62), while both spousal education accounted for 27% (OR 0.49, 95% CI 0.45-0.54) of the total explained variation. The regression results also showed that women with higher standards of living as well as educated women having educated partners had lower odds of facing barriers in getting permission (OR 0.87, 95% CI 0.76-1.00 and OR 0.66, 95% CI 0.58-0.75) to go for advice/treatment, obtaining money (OR 0.43, 95% CI 0.39-0.47 and OR 0.37, 95% CI 0.34-0.40), distance to a health facility (OR 0.60, 95% CI 0.55-0.66 and OR 0.70, 95% CI 0.65-0.76), and not wanting to go alone (OR 0.72, 95% CI 0.66-0.89 and OR 0.75, 95% CI 0.69-0.81) for getting medical advice/treatment. CONCLUSION: The findings of the study suggest paying extra attention to the spousal education and living standard of women to strengthen and reform the existing strategies and develop beneficial interventions to enhance unhindered accessibility to healthcare facilities for women.

Life satisfaction, positive affect, depression and anxiety symptoms, and their relationship with sociodemographic, psychosocial, and clinical variables in a general elderly population sample from Chile.

Background: This study aims to describe the relationship between life satisfaction, positive affect, depression and anxiety symptoms with sociodemographic, psychosocial and clinical variables, and to identify the relative importance of these predictor groups. Methods: We evaluated life satisfaction (SWLS), positive affect (PANAS), depressive (PHQ-9), and anxiety (GAI) symptoms and their association with sociodemographic, psychosocial and clinical variables in a multistage, random general population sample of fully functioning individuals aged 60-80 years from the Concepción province and Gran Santiago, Chile (n = 396). We performed weighted multiple regression analysis, considering the complex sample structure with age group, sex, and geographical area, complemented with general and conditional dominance analyses to estimate the relevance of the predictor groups. Results: We found significant associations with the geographical area, sex, age, education level, household members, having a partner, employment status, caregiver status, economic satisfaction, presence of chronic diseases, medication use, and alcohol use. Satisfaction with health was the most important predictor for positive affect (p < 0.001), depressive (p < 0.001), and anxiety (p < 0.001) symptoms, while alcohol use was the most significant predictor for life satisfaction (p < 0.001). Conclusion: Simultaneously studying the positive and negative dimensions of wellbeing and mental health in older adults allows for a more comprehensive perspective on the challenges faced during this stage of life. This study accounts for previously unknown associations and contributes to the identification of common and specific predictors in both dimensions.

The Effects of Urban Living Conditions on Subjective Well-Being: The Case of German Foreign Service Employees.

In an increasingly urbanized world, understanding the determinants of urban well-being will continue to grow in importance. Although the effects of different indicators of living conditions on well-being have been widely studied individually, little is known about their relative impact when examined jointly. In this study, we use a unique multi-source dataset that allows us to investigate the effect and relative importance of a variety of subjectively and objectively assessed aspects of urban living conditions on the subjective well-being (SWB) of German Foreign Service expatriates. The study captures living conditions in metropolises around the world at different stages of development, and assesses living conditions in a culturally comparably homogeneous set of participants, thus being potentially less confounded with cultural differences. Using linear regression and dominance analysis, we find that 'quality of and access to nature' (i.e., green space), 'quality of housing', and 'quality of public goods' (i.e., water, air, and sewage systems) have the strongest associations with SWB. Subjectively rated characteristics show stronger associations with SWB than externally assessed characteristics. Additionally, we examine whether the size of a city or the level of development of a country has an effect on SWB. Both living in a megacity (≥ 10 million inhabitants) and a lower development status have negative effects on SWB. However, these effects disappear when the various indicators of living conditions are controlled for. Our findings can inform organisations sending employees abroad as well as urban planners seeking to improve their policies and decision-making.

Human cortex development is shaped by molecular and cellular brain systems.

Human brain morphology undergoes complex changes over the lifespan. Despite recent progress in tracking brain development via normative models, current knowledge of underlying biological mechanisms is highly limited. We demonstrate that human cerebral cortex development unfolds along patterns of molecular and cellular brain organization, traceable from population-level to individual developmental trajectories. During childhood and adolescence, cortex-wide spatial distributions of dopaminergic receptors, inhibitory neurons, glial cell populations, and brain-metabolic features explain up to 50% of variance associated with regional cortical thickness trajectories. Adult cortical change patterns are best explained by cholinergic and glutamatergic neurotransmission. These relationships are supported by developmental gene expression trajectories and translate to longitudinal data from over 8,000 adolescents, explaining up to 59% of developmental change at population- and 18% at single-subject level. Integrating multilevel brain atlases with normative modeling and population neuroimaging provides a biologically meaningful path to understand typical and atypical brain development in living humans.

Subjective cognition is linked to everyday functioning in epilepsy.

OBJECTIVE: Many people with epilepsy (PWE) suffer from reduced everyday functioning such as unemployment, relationship difficulties, or lifestyle limitations. To identify whether subjective cognitive impairment (SCI) is a potential source of these impairments, associations with restrictions of daily life (RDL) and reduced daily activities (DA) were examined. METHODS: In a prospective cross-sectional sample of 316 adult in-patients with epilepsy, multiple regression analyses were calculated predicting RDL and DA. The relationships between these two measures and SCI were controlled for age, sex, seizure frequency, presence of structural lesions, epilepsy duration, mono- vs polytherapy and adverse events of antiseizure medication (ASM), level of depressive and anxiety symptoms, education, and employment. We also checked for an interaction between depressive symptoms and SCI, to evaluate whether patients with more depressive symptoms are more vulnerable for unfavorable associations between SCI and RDL or DA, respectively. General dominance indices (GDIs) were calculated to compare predictors. RESULTS: Substantial SCI was present in 46% of our sample. SCI was independently associated with RDL and DA. Comparison of relative predictor importance revealed that SCI accounted for 23% of the total variance of RDL (GDISCI  = 0.12, R RDL 2  = 50%) and 24% of the total variance of DA (GDISCI  = 0.08, R DA 2  = 32%). SCI was among the two most important predictors in both models. PWE with more depressive symptoms had stronger associations between SCI and RDL or DA, respectively. SIGNIFICANCE: Subjective cognitive impairment represents a frequent concern in PWE and may have detrimental consequences for their everyday life. PWE with depressive symptoms may be at greater risk of unfavorable relationships between SCI and everyday functioning. Exchange and collaboration between professionals offering psychotherapeutic, neuropsychological, and psychosocial interventions are crucial to address the patients' individual needs.

Assessing the importance of predictors of adherence to a digital self­management intervention for osteoarthritis.

OBJECTIVE: Treatment adherence is suggested to be associated with greater improvement in patient outcomes. Despite the growing use of digital therapeutics in osteoarthritis management, there is limited evidence of person-level factors influencing adherence to these interventions in real-world settings. We aimed to determine the relative importance of factors influencing adherence to a digital self-management intervention for hip/knee osteoarthritis. METHODS: We obtained data from people participating in a digital OA treatment, known as Joint Academy, between January 2019 and September 2021. We collected data on the participants' adherence, defined as the percentage of completed activities (exercises, lessons, and quizzes), at 3 (n = 14,610)- and 12-month (n = 2682) follow-up. We used dominance and relative weight analyses to assess the relative importance of sociodemographic (age, sex, place of residence, education, year of enrolment), lifestyle (body mass index, physical activity), general health (comorbidity, overall health, activity impairment, anxiety/depression), and osteoarthritis-related (index joint, fear of moving, walking difficulties, pain, physical function, wish for surgery, Patient Acceptable Symptom State) factors, measured at baseline, in explaining variations in adherence. We used bootstrap (1000 replications) to compute 95% confidence intervals. RESULTS: Mean (SD) adherences at 3 and 12 months were 86.3% (16.1) and 84.1% (16.7), with 75.1% and 70.4% of participants reporting an adherence ≥ 80%, respectively. The predictors included in the study explained only 5.6% (95% CI 5.1, 6.6) and 8.1% (7.3, 11.6) of variations in 3- and 12-month adherences, respectively. Sociodemographic factors were the most important predictors explaining more variations than other factors altogether. Among single factors, age with a nonlinear relationship with adherence, was the most important predictor explaining 2.3% (95% CI 1.9, 2.8) and 3.7% (2.4, 5.3) of variations in 3- and 12-month adherences, respectively. CONCLUSION: Person-level factors could only modestly explain the variations in adherence with sociodemographic characteristics, mainly age, accounting for the greatest portion of this explained variance.

A Psychometric and Relative Importance Evaluation of Health Literacy and Health Consciousness on COVID-19 Preventive Behaviors Among Hispanic Adults.

Given the COVID-19 pandemic's disproportionate impact on Hispanic individuals in the United States, research examining modifiable psychosocial correlates of COVID-19 preventive behaviors in this population is warranted. Prior research highlights health literacy and health consciousness as integral for the establishment of health-promoting behaviors. Notwithstanding, very little research has validated theory-based measures for health literacy and health consciousness and no research has investigated their relative importance in explaining behaviors that prevent COVID-19 illness among Hispanic individuals. This information is necessary for informing behavioral interventions seeking to promote the well-being of Hispanic people during the current pandemic and in future ones. This study provides a psychometric evaluation of the General Health Literacy Scale (GHLS) and the Health Consciousness Scale (HCS) and further examines their association with conventional COVID-19 preventive behaviors. Confirmatory factor analyses evaluated the psychometric properties of GHLS and HCS. Four separate hierarchical linear regressions, followed by dominance analyses, estimated the relative importance of health literacy and health consciousness on COVID-19 preventive behaviors, adjusting for sociodemographic characteristics. Both GHLS and HCS achieved adequate psychometric criteria, and holding constant sociodemographic characteristics, positively related to COVID-19 preventive behaviors. Although both health literacy and health consciousness were more important than sociodemographic characteristics in explaining COVID-19 preventive behaviors, health consciousness was most important, exceeding the explanatory power of health literacy in all regressions. COVID-19 public health campaigns that seek to raise health awareness among Hispanic people might prove more effective than campaigns that only seek to improve their health literacy.

Dispositional Mindfulness in Heterosexual and Lesbian/Bisexual Women: Associations with Sexual Prejudice and Internalized Sexual Stigma.

This research investigated the effect of dispositional mindfulness on the reduction of sexual prejudice and internalized sexual stigma in heterosexual and lesbian/bisexual women, who still represent a population that is under-represented in the scientific literature. Participants were 203 Italian women, both heterosexual (N = 104, 51.2%) and lesbian/bisexual (N= 99, 48.8%), ranging between 18 and 68 years old. They responded to a questionnaire containing demographic information and measures of dispositional mindfulness, need for cognitive closure, and adherence to traditional gender roles. Dominance analyses were run to test the predictive power of mindfulness' dimensions on internalized sexual stigma and on sexual prejudice over and above the other predictors. Results showed that having a mindful nonjudging attitude toward one's inner experience is associated with less internalized sexual stigma in lesbian and bisexual women. On the contrary, dispositional mindfulness was not associated with heterosexual women's sexual prejudice against gay and lesbian individuals.

Study on the influencing factors of emergency care nurses′ perceived self-competence in palliative care based on dominance analysis / 中国实用护理杂志

Objective:To explore the relative importance of palliative care knowledge, attitude towards palliative care and healthy work environment of emergency care nurses in predicting perceived self-competence in palliative care based on dominance analysis, and to provide empirical evidence for formulating the optimal training course to improve perceived self-competence in palliative care.Methods:Totally 415 emergency care nurses from 22 tertiary hospitals in Hubei province were conducted a cross-sectional survey to complete the general information questionnaire, the Palliative Care Nursing Self-Competence Scale, the Hospice Knowledge Quiz for Nurses, the Frommelt Attitudes Toward Care of the Dying Scale Form B, and the American Association of Critical Care Nurses Healthy Work Environment Assessment Tool from January to March 2021 using convenient sampling method. Dominance analysis was used for statistical analysis.Results:The total score of perceived self-competence in palliative care of 415 emergency care nurses was (225.48 ± 60.61) points, the total score of palliative care knowledge was (12.44 ± 3.83) points, the total score of palliative care attitude was (97.35 ± 9.07) points and the total score of healthy work environment was (72.00 ± 11.99) points. Perceived self-competence in palliative care was positively associated with palliative care knowledge ( r=0.181, P < 0.01), attitude towards palliative care ( r=0.232, P<0.01) and healthy work environment ( r=0.393, P<0.01). Dominance analysis revealed that the healthy work environment, palliative care attitude and palliative care knowledge accounted for 74.15%, 14.97% and 10.88% of the variance of perceived self-competence in palliative care, respectively. Conclusions:The largest degree of prediction for emergency care nurses′ perceived self-competence in palliative care is healthy work environment, attitude next and the third is knowledge. It suggests that promoting a healthy work environment is an important way to improve nurses′ perceived self-competence in palliative care, and improving knowledge level and cultivating positive attitudes also will be better.

Potential effects of adverse childhood experiences on school engagement in youth: a dominance analysis.

BACKGROUND: Adverse childhood experiences (ACEs) can have severe negative impacts on childhood and adult health via worsened school engagement and educational outcomes. This study seeks to identify the relative importance of various ACEs in predicting school engagement. METHODS: We analyzed data from the National Survey of Children's Health for school-aged children (ages 6-17) for 2018 and 2019. The primary outcome was school engagement, measured through three variables: repeating a grade, doing required homework, and caring about doing well in school. We conducted three logistic regression models with dominance analyses to identify the relative importance of ACE variables in predicting school engagement outcomes. RESULTS: In unadjusted and adjusted dominance analyses, parental incarceration was the most important ACE in predicting repeating a grade. Living in a household in which it was hard to cover basics like food or housing was the most important ACE in predicting doing required homework and caring about doing well in school. DISCUSSION: Our study points toward the large influence of out-of-school factors on school engagement. Parental incarceration and economic hardship, the most important predictors of engagement, are issues that can be addressed and mitigated through policy interventions. With limited funds available for education and public health interventions, it is crucial that these two ACEs be priority considerations when developing policy. A multi-faceted approach that reduces the incarcerated population, encourages economic well-being, and emphasizes early-childhood education has the potential to significantly improve school engagement in vulnerable populations and ultimately advance social equity.
