How is work-family conflict linked to nurse-assessed patient safety among intensive care unit nurses? A serial multiple mediation analysis.

AIM: The aim of this study was to test whether rumination and negative affectivity mediate the relationship between work-family conflict and nurse-assessed patient safety among intensive care unit nurses. BACKGROUND: Most intensive care unit nurses experience work-family conflicts that jeopardise patient safety. Although prior studies have explored the effect of work-family conflict on patient safety, few have investigated whether work-family conflict is associated with patient safety through rumination and negative affectivity among intensive care unit nurses. DESIGN: Cross-sectional study. METHODS: This study included 209 intensive care unit nurses from five general hospitals. The Work-Family Conflict Scale, the Ruminative Response Scale, the Positive and Negative Affect Schedule-Negative Affectivity, and three items indicating nurses' perception of overall patient safety were used to gather data. Associations between work-family conflict, rumination, negative affectivity, and nurse-assessed patient safety were assessed using correlation and serial multiple mediation analysis. RESULTS: Work-family conflict, rumination, negative affectivity, and nurse-assessed patient safety were significantly correlated (p < 0.01). Work-family conflict can have not only a direct negative impact on the nurse-assessed patient safety (effect = -0.0234; standard error [SE] = 0.0116; 95% confidence interval [CI]: lower limit [LL] = -0.0464, upper limit [UL] = -0.0005) but also an indirect impact on nurse-assessed patient safety through three paths: the independent mediating role of rumination (effect = -0.0118; SE = 0.0063; 95% CI: LL = -0.0251, UL = -0.0006), the independent mediating role of negative affectivity (effect = -0.0055; SE = 0.0039; 95% CI: LL = -0.0153, UL = -0.0001), and the chain-mediating role of rumination and negative affectivity (effect = -0.0078; SE = 0.0031; 95% CI: LL = -0.0152, UL = -0.0027). CONCLUSION: Our findings indicated that work-family conflict could influence nurse-assessed patient safety through increasing rumination and negative affectivity among intensive care unit nurses. Based on the results, interventions aimed at decreasing work-family conflict would be beneficial for intensive care unit nurses' emotional stability and patient safety.

La dependencia del ejercicio físico en deportes de resistencia: relación con la regulación emocional y el afecto negativo / Dependence on physical exercise in endurance sports: relationship with emotional regulation and negative affect

El ejercicio físico en altos volúmenes y descontrolado puede generar dependencia psicológica y cambios en el estado de ánimo. La regulación emocional y el afecto negativo son procesos relevantes para el desarrollo de patrones adictivos. Este estudio analizó las diferencias en afecto negativo y regulación emocional en función del perfil de práctica del ejercicio físico; la relación entre la dependencia del ejercicio, la regulación emocional y el afecto negativo; y el papel mediador de la regulación emocional en dicha relación. Participaron 375 practicantes de deportes de resistencia. Las diferencias en los perfiles de práctica del ejercicio físico fueron significativas en todas las variables de estudio. La dependencia del ejercicio correlacionó de forma positiva y significativa con las dificultades de regulación emocional y con el afecto negativo. Las dificultades de regulación emocional fueron predictoras de la dependencia del ejercicio. Hubo un efecto de mediación de las dificultades de regulación emocional entre el afecto negativo y la dependencia del ejercicio. Mejorar las habilidades de regulación emocional podría prevenir la aparición de la dependencia del ejercicio.(AU)

The copious and uncontrolled practice of exercise can generate psychologicaldependence and mood changes. Emotional regulation and negative affectivity arerelevant processes for the development of addictive patterns. This study analysedthe differences in negative affectivity and emotional regulation based on thepractice profile of exercise; the relationship between exercise dependence,emotional regulation, and negative affectivity; and the mediating role of emotionalregulation in such relationship. 375 endurance sports practitioners participated.The differences in the physical exercise practice profiles were significant in all thestudy variables. Exercise dependence correlated positively and significantly withemotional regulation difficulties and with negative affectivity. Emotional regulationdifficulties were predictors of exercise dependence. There was a mediating effectof emotional regulation difficulties between negative affect and exercisedependence. Improving emotional regulation skills could prevent the onset ofexercise dependence.(AU)

The influence of socio-economic status on child temperament and psychological symptom profiles.

The influence of socio-economic status (SES) on child temperament and psychological symptoms was examined using a nationally representative sample in Singapore. Data were available for 2169 children from 1987 families. Caregivers' reports were obtained on children aged 4-6. SES was operationalized as an aggregation of household income per capita, parental education level and housing type. Compared to their counterparts from higher SES families, children from low-SES families tended to exhibit (a) higher negative affectivity but lower effortful control, and (b) higher internalizing and externalizing symptoms. In addition, children with a 'resilient' temperamental profile (i.e. low negative affectivity and high effortful control) were more likely to come from families with much higher SES, relative to children with other profiles. Children with high internalizing symptoms tended to come from low-SES backgrounds, regardless of their externalizing symptoms. Among children with low internalizing symptoms, those with high externalizing symptoms came from lower SES backgrounds compared to those with low externalizing symptoms. Parental warmth and distress mediated the association between SES and child temperament and symptom profiles, with the exception of distress in the SES-temperament link. These findings supported the family stress model and highlighted the novel perspective of SES's influence on configurations of child temperament and symptom characteristics.

Coparenting as a family-level construct: Parent and child inputs across the first two years.

This study examined the effects of infant negative affectivity (NA) and maternal and paternal depressive symptoms on fathers' and mothers' perceptions of coparenting across the first 2 years following an infant's birth. A total of 147 two-parent families (most couples were White, married, and living together) with healthy, full-term infants were recruited. At each time point, fathers and mothers separately reported their coparenting perceptions via the Coparenting Relationship Scale and their depressive symptoms using the depression subscale of Symptom Checklist-90-Revised. Mothers also reported their children's NA via the Infant Behavior Questionnaire-Revised at 3 to 12 months and the Early Child Behavior Questionnaire at 18 and 24 months. Findings from growth curve models in an actor-partner interdependence model framework suggested that among parents with higher depression, there were steeper declines in coparenting quality reported by parents and their spouses across 3-24 months. In addition, three separate two-way interactions between variables including higher-than-usual parental and spousal depression, as well as higher-than-usual infant NA predicted poorer-than-usual coparenting experiences. Findings indicate that coparenting is a dynamically unfolding construct that is impacted by ongoing changes in the parents' social-ecological niche and suggest the need to consider both parent and child characteristics, and to include spousal influences, to get a comprehensive, whole-family understanding of levels and changes in coparenting relationships. The findings also confirm that coparenting dynamics may benefit from interventions engaging both couples and addressing multiple risk factors from both parents (e.g., depression) and children (e.g., NA).

Daily general discrimination predicts changes in trait negative affectivity: A 30-year cohort longitudinal study using a random-intercept cross-lagged panel model.

OBJECTIVE: Increasing evidence indicates discrimination is an emerging risk factor for reducing psychological well-being. Negative affectivity is a personality trait that has been associated with discrimination. Yet, few studies to date have examined the longitudinal relationship between discrimination and personality. The current study addresses this gap by examining how general discrimination and negative affectivity influence each other longitudinally. METHOD: The Midlife in the United States (MIDUS) dataset was used for the current study. The MIDUS sample (N = 4244) was predominately white (90.7%), 52% female, and had an average age of 46 years old. Individuals completed follow-up measures 10 and 20 years after baseline. Data were analyzed using a random-intercept cross-lagged panel model. RESULTS: Individuals that scored higher on trait negative affectivity also tended to score higher on perceived daily discrimination. We found general perceived discrimination at age 55 unidirectionally predicted changes in negative affectivity around retirement age, but not from age 45 to 55. In contrast, negative affectivity did not significantly predict increases in perceived discrimination at any timepoint. CONCLUSION: Our results indicate that perceived discrimination has pernicious impacts on well-being up to a decade later and may do so by increasing an individual's tendency to experience negative emotions (i.e., negative affectivity).

Prospective Mental Images: A Transdiagnostic Approach to Negative Affectivity and Mood Dysregulation among Borderline Personality Disorder and Depression.

There is initial evidence that patients diagnosed with Borderline Personality Disorder (BPD) experience intrusive prospective mental images about non-suicidal self-injury (NSSI). These images, in turn, are associated with the conduct of NSSI. As the negative emotional valence of intrusive images has been established across clinical disorders, negative affectivity might play a key role linking mental imagery and psychopathology. Therefore, the present study aimed to investigate the possible mediating role of symptoms of depression as a proxy for negative affectivity linking intrusive prospective imagery to psychopathology in patients diagnosed with BPD. A total of 233 participants (84 diagnosed with MDD, 66 diagnosed with BPD, 83 healthy controls) completed questionnaires on negative affectivity (BDI-II) and prospective intrusive imagery (IFES-S). Before controlling for negative affectivity, there was a positive correlation between group and intrusive prospective imagery, indicating that healthy participants displayed lower amounts of intrusive prospective images in comparison to patients diagnosed with MDD or BPD. After entering negative affectivity as a mediator, the variable group was no longer associated with intrusive prospective images; however, negative affectivity showed a strong and positive relationship with the group on one side, and intrusive prospective imagery on the other, indicating that negative affectivity mediates the association between intrusive prospective images and clinical disorders. The presented findings point towards a mediating role of negative affectivity in the manifestation of intrusive prospective imagery, not only within BPD, but also in patients with MDD. The possibility of intrusive images acting as a transdiagnostic feature, where negative affectivity and mood dysregulation are at the core of the clinical disorder, are being discussed.

Pathways from adolescent close friendship struggles to adult negative affectivity.

This 19-year prospective study applied a social development lens to the challenge of identifying long-term predictors of adult negative affectivity. A diverse community sample of 169 individuals was repeatedly assessed from age 13 to age 32 using self-, parent-, and peer-reports. As hypothesized, lack of competence establishing and maintaining close friendships in adolescence had a substantial long-term predictive relation to negative affectivity at ages 27-32, even after accounting for prior depressive, anxious, and externalizing symptoms. Predictions also remained robust after accounting for concurrent levels of depressive symptoms, indicating that findings were not simply an artifact of previously established links between relationship quality and depressive symptoms. Predictions also emerged from poor peer relationships within young adulthood to future relative increases in negative affectivity by ages 27-32. Implications for early identification of risk as well as for potential preventive interventions are discussed.

Prospective study of cenobamate on cognition, affectivity, and quality of life in focal epilepsy.

OBJECTIVE: Cenobamate is a recently approved antiseizure medication that proved to be safe and effective in randomized controlled trials. However, little is known about its impact on some areas frequently affected by epilepsy. For this reason, we explored the effects of cenobamate on cognitive performance, as well as on negative affectivity and quality of life in a sample of patients with drug-resistant epilepsy. METHODS: Two prospective cohort studies were carried out. In Study 1, 32 patients (22 men and 10 women) underwent a baseline (T0) and a short-term (T1) neuropsychological assessment after 3 months of cenobamate administration. In Study 2, 22 patients (16 men and 6 women) from the T1 sample also underwent a baseline and a follow-up evaluation (T2) 6 months after T0. RESULTS: No significant differences were found in cognitive variables, negative affectivity, and quality of life either in Study 1 or Study 2. Similarly, based on the reliable change index, it was found that most patients showed no changes in these variables. SIGNIFICANCE: These results suggest that cenobamate is a safe antiseizure medication in terms of cognition, negative affectivity, or quality of life since no adverse events have been found after 3 and 6 months of treatment. PLAIN LANGUAGE SUMMARY: Cenobamate is a new antiseizure medication. In patients with epilepsy, cenobamate seems to not affect cognition, anxiety, depression, or quality of life.

Associations Between Maternal Negative Affectivity and Young Children's Disruptive Behavior Problems: The Mediating Effect of Callous-Unemotional Traits.

The current study examined associations between maternal negative affectivity (NA) and child disruptive behavior problems. The mediating role of child callous-unemotional (CU) traits in these relationships was also investigated. A multilevel mediation modeling approach was adopted using a sample of 100 families with children between 2.5 and 5.5 years of age (N = 201; mean age = 3.8, standard deviation = 1.0). The mediation models showed significant mediating effects of maternal NA through CU traits for ADHD (ß = 0.12, p<.01), ODD (ß =0.13, p<.01), and aggression (ß =0.16, p<.001), and a significant direct effect for aggression (ß = 0.12, p<.05). A structural equation modeling analysis was also performed, and overall, the results were consistent with that from mediation models, which suggested that child CU traits were significantly correlated with maternal NA (ß = 0.252, p<.001), ADHD (ß = 0.504, p<.001), ODD (ß = 0.545, p<.001), and aggression (ß = 0.686, p<.001). Our results indicated that maternal NA could serve as a potential risk factor for child CU, which, in turn, may contribute to disruptive behavior during early childhood.

The relation of psychological status and type D personality with central sensitization in knee osteoarthritis: everything is in your mind!

To evaluate the relation of psychosocial parameters and type D personality with central sensitization in knee osteoarthritis (OA). The study included 126 patients with knee OA according to the American College of Rheumatology criteria. Sociodemographic variables (age, gender, education, marital status, annual income), alcohol consumption/smoking, body mass index, comorbidities, and duration of symptoms were noted. Radiographic evaluation was performed according to the Kellgren-Lawrence grading system. The Western Ontario and McMaster Universities Osteoarthritis Index was used for clinical evaluation. Type D personality, negative affectivity, and social inhibition were evaluated using the type D Scale-14 (DS14). Central sensitization was assessed by the central sensitization inventory (CSI), while psychological status, quality of life, and sleep were assessed by the Hospital Anxiety and Depression Scale (HADS), an abbreviated version of the World Health Organization Quality of Life Instrument (WHOQOL-BREF), and the Jenkins Sleep Evaluation Scale (JSS), respectively. The effect of type D personality on study parameters including central sensitization, as well as the risk factors for the development of central sensitization were assessed by regression analyses. Patients with type D personality had higher CSI, HADS scores and lower WHOQOL-BREF scores for psychological health, social relationship, environment and general quality of life. Linear regression analysis showed that the DS14 total score has a significant positive relation with CSI (ß = 0.4, p < 0.05), HADS-depression (ß = 0.4, p < 0.05), HADS-anxiety (ß = 0.5, p < 0.05), and HADS-total scores (ß = 0.5, p < 0.05). It also had a significant negative effect on all domains of WHOQOL-BREF (p < 0.05 for all). Logistic regression analysis revealed that JSS [Odds ratio (OR) 0.83, 95% CI 0.73-0.94; p = 0.003] and negative affectivity (OR 0.78, 95% CI 0.65-0.94; p = 0.008) were independent risk factors for the development of central sensitization in knee OA. Type D personality has an impact on quality of life, central sensitization, and psychological health, with negative affectivity and sleep impairment serving as independent risk factors for central sensitization. While managing patients with knee OA, these intimate relationships should be taken into consideration.

The role of student-teacher relationships in the association between negative parenting practices and emotion dynamics - Combining longitudinal and ecological momentary assessment data.

Emotion dysregulation is increasingly implicated as a transdiagnostic risk factor in the etiology of mental health problems. This project aimed to explore the links between emotion regulation, negative parenting and student-teacher relationships using longitudinal and ecologically valid data. A sample of n = 209 young people enrolled in the 'Decades-to-Minutes' (D2M) study, based in Zurich, Switzerland, provided data from the ages of 7-20 via parent- and self-report questionnaires and ecological momentary assessment. Data were analyzed using Dynamic Structural Equation Modeling (DSEM). Worse student-teacher relationships predicted increased negative affectivity and emotional lability. Negative parenting practices predicted emotional lability only via their impact on student-teacher relationships. The findings point to worse student-teacher relationships as risk factors in the socioemotional development of children and young people.

Emotion dynamics and somatic symptoms in everyday life: Ecological momentary assessment in somatic symptom disorder and healthy controls.

OBJECTIVE: Negative affectivity (NA) is associated with the emergence and persistence of physical symptoms with unclear organic pathology. This study investigated the temporal dynamics of NA and somatic symptom burden using ecological momentary assessment (EMA) in adults with somatic symptom disorder (SSD) and healthy control participants (HC). METHODS: Participants underwent a seven-day, smartphone-based EMA, with 6 randomly-stratified time points per day. NA was assessed using a five-item short form of the Positive and Negative Affectivity Scale (PANAS) and somatic symptom burden with two self-constructed items. 22 persons with SSD and 20 HCs were included in multilevel analyses. RESULTS: Within-person analyses showed a significantly stronger (positive) association of concurrent NA with somatic symptom burden in participants with SSD than in HCs, ß = 0.15, SE = 0.04, p = .001. Time-lagged analyses demonstrated that, across groups, NA at a previous time point t-1 significantly predicted somatic symptom burden at the subsequent timepoint t, ß = 0.09, SE = 0.03, p = .005, but not in the other direction (somatic symptom burdent-1→ NAt, ß = 0.01, SE = 0.04, p = .79). Between-person analyses showed that both inertia (i.e., persistence of negative affective states), d = 0.74, and instability (i.e., magnitude of moment-to-moment fluctuations), d = 0.76 of NA were significantly higher in participants with SSD than in HCs. CONCLUSIONS: Our findings sustain the idea of (negative) affect-driven modulation in somatic signal processing and suggest that interoceptive and emotional differentiation training can advance the psychotherapeutic treatment of SSD.

The longitudinal contributions of child language, negative emotionality, and maternal positive affect on toddler executive functioning development.

Executive functions (EF) develop rapidly across early childhood and play a prominent role in promoting adaptive outcomes later in development. Although the existing literature suggests that the development of early EF is sensitive to the influence of intrinsic and extrinsic factors, limited research has examined the joint contributions of multiple child and contextual factors in infancy/toddlerhood. The purpose of our longitudinal study was therefore to identify early environmental, behavioral, biologically-based factors that influence children's EF outcomes in late toddlerhood. Participants included 409 mother-child dyads (209 girls) and the data was collected across children's first three postnatal years. Parent-report measures were used to assess infant negative affectivity (5-months; IBQ-R) and toddler language (age 2; MCDI), and both maternal positive affect (5-months) and toddler frustration (age 2) were coded during mother-child interaction tasks. A battery of behavioral tasks was used to measure child EF in late toddlerhood (age 3). After controlling for maternal education (a proxy for children's socio-economic environment), path analysis indicated that both infant and maternal affect at 5-months directly predicted toddlers' language skills and frustration expression at age 2. Toddler language (but not frustration) also predicted child performance on multiple EF tasks at age 3. Finally, 5-month infant and maternal affect indirectly predicted age 3 EF via age 2 language. Our results identify language as a mechanism through which children's early caregiving environment influences their EF development. Taken together, these findings illustrate the importance of applying a biopsychosocial perspective to the examination of early childhood EF development.

The roles of child temperament, parent stress, and parenting style in family mealtimes.

Family mealtimes are associated with benefits for children, including healthy eating, fewer behavior problems, and healthy psychological well-being. However, the interactions during family mealtimes, and the parent and child characteristics, which may affect both the family mealtime environment and the associated benefits in children are not fully understood. The goal of this study was to examine the role of child and parent characteristics on the family mealtime environment. We tested several mediation models to explain how child temperament (negative affectivity), parent stress, and the dimensions of parent feeding style (responsiveness and demandingness) interact and influence each other to impact the structure and quality of the mealtime environment. Parents (68 mothers; 82 fathers) of children between 2 and 6 years completed an online survey. Measures included the Children's Behavior Questionnaire, Perceived Stress Scale, Caregiver's Feeding Styles Questionnaire, and The Meals in Our Household Questionnaire. Child negative affectivity was associated with poorer mealtime quality and structure. These associations were mediated through parent responsiveness, but not demandingness. The role of demandingness in family mealtimes may depend on parent responsiveness. When examined together in a serial mediation model, child negative affectivity increased parent stress, which reduced responsiveness, and led to poorer mealtime quality and structure. These results emphasize the complex relationships between child temperament, parent stress, and the dimensions of parenting styles that occur within the mealtime context. This line of research is essential for understanding family mealtime dynamics and informing future studies aimed at creating positive interactions between parents and children during mealtimes.

Child temperament is associated with energy intake and its day-to-day variability among preschoolers-Results from a cross-sectional DAGIS study.

BACKGROUND: Although research has linked children's temperament with weight outcomes, the associations between temperament and dietary outcomes, particularly energy intake, remain understudied. Furthermore, little is known about how temperament is associated with diet in the early childhood education and care (ECEC) context, which is an important environment for many children. OBJECTIVES: This study examined whether temperament is associated with mean energy intake and its day-to-day variability. In addition, the associations were examined separately in the contexts of home and ECEC. METHODS: The study used data from 505 Finnish children from a cross-sectional DAGIS study conducted in 2015-2016. Parents reported their child's temperament with a questionnaire and food consumption with a food record for two weekdays (outside daycare hours) and one weekend day. Early educators at an ECEC centre reported the child's food consumption during the daycare hours on the same weekdays as the parents kept food records at home. Associations were examined with linear regression models. RESULTS: Children with higher surgency had a higher mean daily energy intake. When examined separately at home and in the ECEC centre, the association was found only in the ECEC centre. Children with higher negative affectivity had greater day-to-day variability in energy intake. This association, however, was not observed when examined separately at home and at the ECEC centre. CONCLUSIONS: The results indicate that temperament may shape children's energy intake. Moreover, the role of the ECEC context in children's eating may be different depending on a child's temperamental dispositions, which warrants further research.

The Interdependent Nature of Mother's and Children's Temperament and Eating Behaviors on Weight.

OBJECTIVES: The family environment is an important contextual factor for parent and child weight within families. Using an Actor-Partner Interdependence Model, the current study examined (1) the effect of child and mother temperament (i.e., negative affectivity, effortful control, and impulsivity) on mother and child weight, (2) the effect of mother eating behaviors on mother and child weight, and (3) how temperament might moderate the relationships between mother eating behaviors and mother and child weight. METHODS: The sample consisted of 220 mother-child dyads with children between 4 and 6 years of age (66.8% classified as low-, 25.9% middle-, and 5.5% high-income). Mothers completed questionnaires on their own temperament and eating behaviors as well as child temperament. Weight measures were assessed in the laboratory for both mother and child. RESULTS: Mother's negative affectivity and impulsivity were negatively related to mother's weight while children's impulsivity was positively related to children's and mother's weight. Mother's eating behaviors were also positively related to mother's weight. The interaction between child impulsivity and mother eating behaviors was significant; the association of mother eating behaviors with mother weight depended on child impulsivity. Specifically, when children had higher impulsivity, mothers had the highest weight. When children had average or lower impulsivity, mother weight was higher with higher endorsement of unhealthy eating behaviors. CONCLUSIONS: Findings suggest that after adjusting for the interdependent nature of temperament traits and weight, child impulsivity is an important factor associated with current weight for both mothers and children. Results also provide important implications for the impact children can have on their mothers.

Self-esteem and negative affectivity as mediators of the prospective links between adolescent interpersonal peer problems and disordered eating behaviors.

The current prospective study examined whether both self-esteem and negative affectivity mediate subsequent associations between interpersonal peer problems (i.e., peer victimization, peer rejection, lack of friendships) and disordered eating behaviors (i.e., loss of control while overeating, emotional eating, restrained eating) in adolescents using secondary data. The sample included 2051 adolescents (Mage baseline = 13.81, SDage baseline = 0.72; 48.5% female) who participated in a longitudinal project, which includes three annually collected waves of data. Participants completed self-report and peer-report measures describing interpersonal problems with peers, and self-report measures describing negative affectivity, self-esteem, and disordered eating behaviors. The results provided no support for either self-esteem or negative affectivity as mediators of the associations between interpersonal peer problems and disordered eating behaviors two years later. However, self-esteem was more robustly linked to all three types of subsequent disordered eating behaviors than negative affectivity. This highlights the importance of adolescent's self-evaluations in the development of disordered eating behaviors.

Clinical-Immunological Correlates in Post-COVID-19 Endogenous Psychoses.

Objectives. To carry out a clinical and immunological study of the potential impact of coronavirus infection on the course of endogenous psychoses. Materials and methods. A total of 33 female patients aged 16-48 years with depressive-delusional states (F20.01, F21, F31) developing after coronavirus infections took part; group 1 consisted of 15 people who developed depressive-delusional states 1-2 months after COVID-19; group 2 consisted of 18 people with similar psychoses developing at later time points (2-6 months). The severity of psychopathological symptoms was assessed using the PANSS and HDRS-21 scales. The activity of inflammatory markers leukocyte elastase (LE) and α1-proteinase inhibitor (α1-PI) was determined in patients' blood. Absolute neutrophil and lymphocyte contents and their ratio (the neutrophil:lymphocyte index) were also evaluated. Standard values for indicators from healthy donors corresponding to patients in terms of age and sex were used as control values. Results. Endogenous psychosis developing at longer intervals after coronavirus infection (group 2) was found to be associated with "typical" inflammatory reactions, with increases in the activity of acute-phase proteins (α1-PI: 43.0 (35.6-49.7) IU/ml, p = 0.001) and neutrophil degranulation activity (LE - 254.8 (238.0-271.0) nmol/min·ml, p < 0.001), which was associated with the development of depressive-delusional states with dominance of manifestations of positive affectivity (anxiety, melancholy) and the extended nature of delusional disorders, which were mostly incongruent to affect. Conversely, development of endogenous psychosis during the first two months after COVID-19 (group 1) was characterized by a spectrum of inflammatory biomarkers with a decrease in neutrophil count ((2.6 ± 0.9)·109/liter, p < 0.05) and low LE activity (196 (172-209.4) nmol/min·ml, p < 0.001). This immunological profile was associated with predominance of manifestations of negative affectivity (apathy, asthenia, adynamia) in the structure of depressive-delusional states and the relatively undeveloped nature of delusional disorders, which were predominantly congruent to affect. Conclusions. The clinical and biological correlates found here presumptively indicate that experience of COVID-19 infection has a modulatory effect on neuroinflammation and the structure of endogenous psychosis.

The underlying mechanism between compulsory citizenship behaviors and employee innovative work behaviors and knowledge sharing: A moderated mediation model.

Purpose: This paper draws on conservation of resources theory to advance the literature on extra-role performance behaviors among academics, particularly innovative work behaviors and knowledge sharing, through the lens of work stressors. Methods: We develop a moderated-mediated model based on multi-source, multi-timed, and multi-level data from a sample of 207 academics and 137 direct supervisors in five higher education institutions in the United Arab Emirates (UAE). Findings: Results show that academics' compulsory citizenship behaviors positively influence negative affectivity, which, in turn, negatively impacts academics' innovative work behavior and knowledge sharing. The detrimental effect of compulsory citizenship behaviors on negative affectivity is then positively moderated by passive leadership, which amplifies this relationship. The combined effect of compulsory citizenship behaviors and negative affectivity exerted on innovative work behavior and knowledge sharing are magnified amid the elevated presence of passive leadership, while gender does not significantly influence this association. Originality: This is a pioneering study in the context of UAE to look into the counterproductive impact of CCB on employee innovative work behaviors and knowledge sharing. Implications: Pertinent theoretical and managerial implications are discussed.

Infant negative affectivity and patterns of affect-biased attention.

Biased attention toward affective cues often cooccurs with the emergence and maintenance of internalizing disorders. However, few studies have assessed whether affect-biased attention in infancy relates to early indicators of psychopathological risk, such as negative affectivity. The current study evaluates whether negative affectivity relates to affect-biased attention in 6-month-old infants. Affect-biased attention was assessed via a free-viewing eye-tracking task in which infants were presented with a series of face pairs (comprised of a happy, angry, or sad face and a neutral face). Attention was quantified with metrics of both attention orienting and attention holding. Overall, infants showed no differences in attention orienting (i.e., speed of looking) or attention holding (i.e., duration of looking) toward emotional faces in comparison to the neutral face pairs. Negative affectivity, assessed via parent report, did not relate to attention orienting but was associated with biased attention toward positive, happy faces and away from threat-cueing, angry faces in comparison to the neutral faces they were paired with. These findings suggest that negative affectivity is associated with differences in attention holding, but not initial orienting toward emotional faces; biases which have important implications for the trajectory of socioemotional development.
