Emotional self-regulation and personality in the light of Thomas Aquinas's philosophical anthropology.

This article aims to thoroughly understand the concept of emotional self-regulation (ESR) and its relationship with personality. Through an interdisciplinary dialogue between psychology and philosophy-specifically, the anthropology of Thomas Aquinas-three realities are proposed that could be considered as ESR. The conceptual relationship between ESR-understood as operation, faculty and habit-and personality is examined, specifically using the Five-Factor Model and the virtues model. Key findings include the need for consensus on a precise definition of ESR, the central role of reason as a faculty capable of ruling over emotions, the relevance of the distinction between ESR and self-control, and the understanding of ESR as a set of habits that include aspects of prudence, temperance and fortitude. Interdisciplinary dialogue seems to be a valuable intellectual approach to the advancement of the field of psychology.

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)

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)

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).

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.

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.

Differential Impact of Emotional and Contextual Factors Associated with COVID-19 on Adolescent Mental Health.

Background: During the confinement, there was an increase in the incidence of mental disorders such as depression and anxiety. In this regard, affectivity is of particular interest, as emotions play a fundamental role in overall mental health. The literature on COVID-19 in this population has often focused on the analysis of risk factors for mental health, while less attention has been paid to protective factors. In this paper, we propose an inclusive model of risk and protective factors for adolescent mental health through the indirect effect of negative and positive affect. Methods: This was a cross-sectional study with a Spanish community sample of 477 adolescents (Mage = 16.23, range:14 to 20 years old; 43.4% were boys; response rate: 100%). We measured the perceived hardness of confinement, worrying about contagion, quality of relationships at home, pleasant activities, affect (positive and negative), and mental health. Results: The results revealed a positive relationship between the perceived hardness of confinement and worrying about contagion with mental health, through the indirect effect of negative affect, and a positive relationship between home relationships and pleasant activities with mental health through an indirect effect of positive affect. Conclusion: Our results suggest that different types of emotions generated by the various contextual variables associated with COVID-19 may have a differential impact on mental health. These findings support the inclusive model of risk and protective factors for adolescent mental health. Practical implications, future studies, and limitations are discussed.

The Boomerang Effect of Suppression of Emotional Expression: Relationship Power, Affectivity and Adolescent and Youth Male-To-Female Dating Violence.

Scarce research has been performed on the role of power, affectivity, and suppression of emotional expression in the use of dating violence by adolescents and young men. This study aims to analyze a model of the associations between perceived power (control and dominance), affectivity (positive and negative affect), suppression of emotional expression and the frequency of use of male-to female dating violence. Participants in this cross-sectional and correlational study were 786 Spanish students aged between 13 and 25 years (M = 18.80; SD = 2.93) divided in two groups: 13-18 (316 adolescents, M = 15.58; SD = 1.02) and 18-25 (462 young men, M = 20.79; SD = 1.98) with 8 participants not stating their age. Different sequential mediation models confirmed that, only in young men, affectivity (negative and positive affect) and suppression of emotional expression mediate the relationship between power and the use of dating violence. Fostering equal relationships, associating them with positive emotional states, avoiding the frustration derived from low power perception, and providing young men with strategies for appropriately expressing their emotions may help decrease the use of dating violence.

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.

Affectivity and satisfaction in the relationship of Pakistani couples is mediated by dyadic coping-based gratitude.

A substantial body of research supports a positive association between interpersonal gratitude and relationship satisfaction in couples; however, dyadic coping-based gratitude (DC-G) has not been investigated from a dyadic stress and coping perspective. The current study aimed to investigate the mediating role of DC-G between trait affectivity and relationship satisfaction in couples. We collected data from both members of dyads (N = 300 married couples) for the study variables as a pre-requisite for conducting dyadic data analysis using an actor-partner interdependent mediation model (APIMeM). The findings suggest that husbands' positive affect significantly predicted wives' relationship satisfaction via DC-G (actor-partner effect). However, the mediating effect of DC-G appeared to be stronger for the actor-actor and partner-partner effects compared with the cross-partner effect, which supports the actor-only effect. Further, wives' DC-G mediated between husbands' negative affect and wives' relationship satisfaction, suggesting a mediating effect of DC-G for wives but not for husbands. The implications are discussed within the context of couples' relationships.

Personality predicting military morale and the role of positive and negative affectivity.

BACKGROUND: Military morale is defined as the enthusiasm and persistence with which a member of the group engages in the prescribed activities of that group and is considered to be closely related to performance. The current study uses the conceptualization of military morale through the elements of work engagement and burnout. Nevertheless, our personality traits, and how we interpret or react to our environment, including group atmosphere, may also be related to perception of morale alongside positive and negative affectivity. The article investigates the relations between perceptions of morale, personality traits (the Big Five) and positive or negative affectivity in a military context. PARTICIPANTS AND PROCEDURE: A sample of Estonian military conscripts (N = 354) from the soldiers' basic military training course responded to the questionnaire. Three measures were used for data collection: a short personality questionnaire (40 items) for Big Five personality traits; the Positive and Negative Affect Schedule (PANAS; 20 items) for state affectivity (both positive and negative); and a 16-item instrument for military morale (8 items for both work engagement and burnout). Structural equation modelling was used to evaluate relationships between study variables. RESULTS: The results indicated that openness to experience and agreeableness did not have a significant effect on military morale (as work engagement and burnout) either directly or indirectly (through affectivity). However, conscientiousness was found to have a significant effect on military morale and extraversion indirectly through positive affectivity. Positive and negative affectivity as the mediators strengthened the relations between personality traits and military morale. CONCLUSIONS: The results emphasize the reinforcing power of positive emotions to enhance high morale.

Affectivity in danish patients with emotional disorders: assessing the validity of the Positive and Negative Affect Schedule (PANAS).

BACKGROUND: The Positive and Negative Affect Schedule (PANAS) was designed to measure trait positive affect (PA) and trait negative affect (NA). METHODS: The Danish PANAS was administered to outpatients with depression and anxiety disorders. Internal consistency was assessed using Cronbach's alpha and McDonald's omega and factorial structure was evaluated using confirmatory factor analysis (CFA). Convergent validity was evaluated by means of correlations with the negative affectivity and the detachment domain of the Personality Inventory for DSM-5 Short Form (PID-5-SF), the Hamilton Anxiety Rating Scale 6 (HARS-6) and the Hamilton Depression Rating Scale 6 (HDRS-6). RESULTS: PANAS Scores of 256 patients were analyzed. Cronbach's alpha and McDonald's omega showed good internal consistency for both the PA score (alpha = .84 and omega = .89) and the NA score (alpha = .86 and omega = .90). CFA analysis confirmed a structure with two factors corresponding to the PA and NA factors. PA was negatively correlated with the detachment domain of PID-5 (r = -.47), HARS-6 (r = -.15) and HDRS-6 (r = -.37). NA was positively correlated with PID-5-SF negative affectivity domain (r = .43), HARS-6 (r = .51) and HDRS-6 (r = .52). DISCUSSION: The Danish PANAS has promising internal consistency and construct validity, which are comparable to other studies of the instrument.

Incels, autism, and hopelessness: affective incorporation of online interaction as a challenge for phenomenological psychopathology.

Recent research has drawn attention to the prevalence of self-reported autism within online communities of involuntary celibates (incels). These studies suggest that some individuals with autism may be particularly vulnerable to the impact of incel forums and the hopelessness they generate. However, a more precise description of the experiential connection between inceldom, self-reported autism, and hopelessness has remained unarticulated. Therefore, this article combines empirical studies on the incel community with phenomenological and embodiment approaches to autism, hopelessness, and online affectivity. We analyze three interrelated aspects of online interactions in incel communities - worldview, bodily self-relation, and mutual dismissals - and examine how these elements contribute to the consolidation of the loss of significant life possibilities. By investigating the potential negative influence of specific online environments on affective dispositions, our approach contributes to the debate on current challenges to "situate" phenomenological psychopathology.

Promoción de la salud afectiva-sexual en primera infancia, contexto de cuido y educativo en Costa Rica. Una revisión crítica / Affective-sexual health promotion in early childhood: critical review in the context of childcare and education in Costa Rica

Resumen La presente revisión describe investigaciones sobre el desarrollo afectivo-sexual en primera infancia en el ámbito preescolar y de cuido; éstas se analizan desde el marco normativo y operativo en el cual se sustenta la educación sobre este tema en Costa Rica. Dicha revisión se realizó con 4 bases de datos internacionales y se sustentó en estudios empíricos y de revisión. Los estudios hallados apuntan a una diversidad de procesos a tomar en cuenta. Algunos de éstos se relacionan con el desarrollo de vínculos seguros y confiables, el uso de terminología genital desde temprana edad, abordajes asertivos de las manifestaciones afectivas-sexuales de infantes, así como a contemplar los aspectos culturales y socio-históricos. A nivel nacional se encuentra que existe un amplio marco normativo que respalda la comprensión integral del desarrollo afectivo-sexual para su abordaje. Sin embargo, se observa que en el programa nacional de preescolar, se prioriza el riesgo al abuso sexual. Además en este se devela una visión moralista por edades, considerando que los genitales deben nombrarse sólo en los últimos niveles de preescolar y no cuando se conocen las partes del cuerpo en los niveles iniciales. Desde un enfoque de promoción de la salud sexual en el ámbito de cuido y educativo nacional, aquí se propone una visión más amplia que tiene plenamente en cuenta las complejidades en torno a los determinantes sociales del desarrollo afectivo sexual. Por lo que se requiere una actualización del programa de preescolar, acompañado de formación continua para el personal y las familias de infantes.

Abstract This critical review describes research on affective and sexual development in early childhood in preschool and childcare settings. Studies are analyzed from the point of view of the regulatory and operational frameworks on which education on this topic in Costa Rica is based. The review was carried out using 4 international databases, examining empirical studies and review studies. Costa Rica has put in place a broad national-level policy framework that supports a comprehensive understanding of affective-sexual development from infancy. However, implementation of the policy in the national preschool program does not always meet the framework's standards. We find that the risk of sexual abuse tends to be prioritized in early sexual-affective education. Sexual-affective development is often addressed from a moralistic standpoint, advising for instance that the genitals should be named only in the last levels of preschool and not when the other parts of the body are first named. From a health-promotional perspective on national childcare and early education, we here propose a broader view that takes fully into account the complexities around the social determinants of sexual-affective development. We conclude that an update of the preschool program is required, accompanied by continuous training for staff and families of infants.

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.

Affectivity, sexuality, and autism spectrum disorder: qualitative analysis of the experiences of autistic young adults and their families.

BACKGROUND: Autistic people have communication, sensorial, and social difficulties, which on many occasions, make their adaptation on the sexual and affective levels difficult. For this reason, it is important to know the opinion of individuals with autism spectrum disorders (ASD) and their families, to offer this perspective to professionals to facilitate adapted health education programs in mental health units. METHODS: This qualitative descriptive design presents the experiences of autistic individuals and their families in relation to the affective-sexual experiences from individual, family, and social perspectives. Two focus group sessions were held with eight family members and seven individual semi-structured interviews with autistic young adults. The transcripts were qualitatively analysed using content analysis. RESULTS: Four themes (Family and social dynamic; Social behaviour of the autistic individual; Affective-sexual relationships; Addressing affective and sex education) and 13 related categories emerged from these results. Communication and social interaction problems act as barriers for young adults when developing affective-sexual relationships, leading to the emergence of negative feelings and experiences that reinforce avoidance behaviours, further intensifying their difficulties in interacting with others. Families, especially mothers, exhibit a poor perception of their ability to provide affective-sexual guidance, leading to anxiety and frustration. There are also reports of poor sex education and lack of support systems. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: The experiences of young people and their families are sometimes conflicting when it comes to affectivity and sexuality, but the parental role emerges as relevant in the sex education process. Families play a pivotal role in sex education, which is why professionals should provide them with support and information through health education programmes, foster empathetic communication and promote sexual and emotional development that is adapted to the characteristics and interests of autistic people.

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 impact of negative and positive affectivity on the relationship between work-related psychological factors and work engagement in Japanese workers: a comparison of psychological distress.

BACKGROUND: A previous study has shown that Japanese individuals generally exhibit behavior that suppresses the expression of positive emotions, which are strongly affected by affectivity traits. In the present study, to clarify the relationship between affectivity traits and work engagement (WE) or work-related psychosocial factors among Japanese workers, we compared it to the association between psychological distress and these same factors. METHODS: A total of 1,000 full-time Japanese regular workers responded to an online survey that measured demographic variables, negative and positive affectivity, job demands and resources, WE, and psychological distress. A hierarchical multiple regression analysis was conducted separately, which used WE and psychological distress as dependent variables. RESULTS: The proportion of variance explained by negative and positive affectivity was lower for WE than for psychological distress. However, the proportion of variance defined by job demands and resources was higher for WE than for psychological distress. The proportion of variance explained by all variables for negative and positive affectivity and job demands and resources, and their interactions was approximately equal for WE and psychological distress. CONCLUSION: These results emphasize when researchers aim to evaluate the change of psychosocial factors in the workplace, such as improving the workplace environment among Japanese workers, it might be beneficial to measure positive indicators in addition to negative indicators. Furthermore, enriching job resources would be effective in improving WE and alleviating psychological distress.
