Trait neuroticism, time of day, and day of the week were assessed as predictors of state fatigue. After completing an in-lab questionnaire, 176 participants (N = 176) reported their state subjective fatigue three times a day for 8 days. Trait neuroticism was shown to be a predictor of subjective fatigue states in the morning, early evening, at bedtime, and over the course of the 8-day study period. Additionally, results indicated statistically significant differences in subjective fatigue at different points in the day. A statistically significant Neuroticism X Day of the Week interaction indicated that the neuroticism -fatigue relationship was strongest on Tuesday and weakest on Sunday. The relative contribution of personality, time of day, and day of the week variables to state subjective fatigue are discussed.

<p>The aim of the present study was to investigate the connection between anger, personality, stress and gender in 165 students from Växjö University. Previous research has shown that anger is a common negative emotion that occurs in every human being, regardless gender. Anger correlates positively with neuroticism and affects physical and psychological well-being. The questionnaire contained State-Trait Anger Scale (STAXI-2-S), Eysenck´s Personality Questionnaire (EPQ) and the Demand-Control-Support model (DCS). The result showed that there was a significant relation between neuroticism and anger. Anger also correlated positively with support but there were no gender differences in any level of anger.</p>

Recently there has been increased interest in using employment interviews to judge personality (Christiansen, 2005; Powell & Goffin, 2009). However, not all personality traits are accurately detected. Previous research has demonstrated that Neuroticism is a trait that is difficult to correctly identify (Lippa & Dietz, 2000; Powell & Goffin, 2009; Watson, 1989). Neuroticism differs from the other Big Five traits because it is more affective in nature. It is proposed that those that are superior at detecting emotions in others will be better at judging Neuroticism in others. The purpose of the current research is to examine the relationship between emotional intelligence(specifically accuracy at detecting emotions) and accuracy in making personality judgments. A significant relation was found between emotional intelligence and accuracy in detecting Neuroticism. Implications for research and practice are discussed.

Tidigare forskning har visat att det finns ett samband mellan personlighetsdraget neuroticism och yttre motivation, a-motivation, låg självkänsla samt negativ affekt. Syftet med studien var att öka förståelsen för neuroticism som personlighetsdrag utifrån individernas motivationstyp, självkänsla samt individernas affektiva tillstånd. Studien undersökte även reliabiliteten hos instrumentet Mini-IPIP som har undersökt personlighetsdrag inom Big-five-teorin. Syftet testades med hjälp av fyra självskattningstester. Dessa var Mini-IPIP, Situational Motivation Scale (SIMS), Positive Affect and Negative Affect Scale (PANAS) samt Rosenbergs Self-esteem Scale (SES). I studien deltog N=110 deltagare i åldrarna 19-53 år. I avsikt att bättre förstå neuroticism och dess relation till motivation, självkänsla samt affekt genomfördes statistiska analyser såsom korrelation och regressionsanalys. Resultatet visade, med hjälp av en korrelation, att det fanns ett samband mellan negativ affekt och neuroticism som personlighetsdrag. Regressionsanalysen bekräftade samband mellan neuroticism som personlighetsdrag och motivationstyperna a-motivation samt yttre motivation. Dock kunde inget samband mellan neuroticisms och självkänsla bekräftas.

Tidigare forskning visar att personlighet har betydelse för individens stressupplevelse. Särskilt individer högt i Fem-Faktor modellens personlighesdimension neuroticism tenderar att upplevd högre stressnivåer än övriga fyra personlighetsdimensioner extraversion, samvetsgrannhet, öppenhet och sympatiskhet. Denna studie undersökte relationen mellan samtliga personlighetsdimensioner, samt en del övriga variabler, och stress. Detta skedde utifrån fyra frågeställning med fyra tillhörande hypoteser. 152 högskolestudenter deltog genom att besvara en enkät som bestod av översatta versioner av Shafer’s Five-Factor Personality Scale samt Cohen, Kamarck och Mermelsteins Perceived Stress Scale. Samt nio övriga bakgrundsvariabler. Insamlad data undersöktes med korrelationer, regressionsanalys, t-test och variansanalys. Resultatet visade, i linje med tidigare studier, att personlighet har betydelse för upplevd stress. Högt neurotiska individer upplever mest stress. I denna studie kunde 36 % av variationen i stressupplevelse förklaras av personlighet.

abstract: Theoretical models support conceptualizing parent-child relationships as reciprocal and transactional with each person exerting influence on the other’s behaviors and the overall quality and valence of the relationship across time. The goals of this study were twofold: 1) determine whether there were reciprocal relations in maternal hostility and child negativity across early and middle childhood, and 2) investigate whether individual characteristics (i.e., child temperamental anger and frustration and maternal neuroticism) moderated relations found in goal one. Data were from the Study of Early Child Care and Youth Development. Empirical support was found for conceptualizing mother-child interactions as reciprocal. Maternal hostility was related to a decrease in the probability children would exhibit negative behaviors during mother-child interactions measured approximately two years later. Child negativity was also associated with a significant decrease in the probability mothers would display future hostility. Child temperamental anger and frustration was found to moderate reciprocal relations across all three parent-to-child cross-lagged paths. Children scoring high on a dispositional proclivity to react with anger and frustration were more likely to avoid maternal hostility, via a significant decrease in negativity, across time. Moderation was also supported in two of three child-to-parent lagged paths. Finally, maternal neuroticism moderated the reciprocal effects during early childhood, such that more neurotic mothers were more likely to demonstrate a decrease in the probability of hostility relative to mothers scoring lower on neuroticism. This affect was attenuated in middle childhood, with patterns becoming similar between mothers scoring high and low on neuroticism. Moreover, children of less neurotic mothers were more likely to demonstrate a decrease in the probability of exhibiting negativity from 36 to 54 months compared to children of more neurotic mothers. This effect also attenuated with patterns becoming negative at the grade 1 to grade 3 lag. Overall, the results from this study supported a transactional model of parent-child relationships, were consistent with the motivation literature, did not support a coercive process of interaction when the sample and measurement paradigm were low-risk, and generally suggested parents and children have an equal influence on the relational processes investigated from early to middle childhood. / Dissertation/Thesis / Doctoral Dissertation Family and Human Development 2016

Much of the literature regarding relational aggression in romantic relationships has focused on the behaviors and outcomes of the actor and victim independently. Additionally, the relationships studied usually cover emerging adult samples, and rarely expand to long-term committed relationships, such as cohabiting or married couples. In this paper I sought to determine if relationally aggressive behaviors in long-term committed relationships over time resulted as a function of individual predictors (e.g. neuroticism), or as a process of couple interactions (e.g. couple attachment); and how these traits directly and indirectly (through relational aggression) influenced relationship quality. An Actor Partner Independence Model (APIM) was run using 1,558 individuals from the RELATE study. Anxious attachment was the strongest predictor of relational aggression. For both men and women, participating in relationally aggressive behaviors had a direct influence on their own relationship quality. Anxiously attached partners were more likely to be relationally aggressive and to have more relationally aggressive partners. Female, as well as male, relational aggression partially mediated the link between male and female anxious attachment, and female relationship quality. For men, only their own relational aggression mediated the link between male and female anxious attachment, and their own relationship quality.

Few studies have investigated the relationships among resilience, optimism, and personality traits with U.S. college students; although some work has been done with Chinese university students. The current study explores the relationship between resilience, optimism and the Big Five personality traits. A sample of 251 undergraduate students completed the Connor-Davidson Resilience Scale (CD-RISC), the 9-item version of the Personal Optimism & Self-Efficacy Optimism Scale (POSE-E), and the NEO- Five Factor Inventory (NEO-FFI). Results indicate a significant positive relationship between resilience and optimism. The results also indicate positive significant relationships between resilience and extraversion, as well as resilience and conscientiousness. A significant negative significant relationship between resilience and neuroticism was found. The results of this study helpful identify characteristics of students who are at-risk following life stressors and traumas.

The goal of this thesis was to examine the relationship between personality types (i.e., extraversion and neuroticism) and anxiety levels among college students during the height of the pandemic. Specifically, this study examined whether factors contributed to anxiety and whether differences in anxiety scores differed by personality trait. It was hypothesized that individuals who scored high in both extraversion and neuroticism would report an increase in anxiety during the height of COVID-19 pandemic. Neuroticism is linked to emotional responses to a negative event (e.g., such as COVID), which may play a role on anxiety levels. The level of extraversion that an individual displays may predict social preferences, and in turn, their reaction to the situations that create isolation such as the pandemic. A cross-sectional study was conducted with 163 students at the University of Central Florida, who completed a survey that measured anxiety levels before and after the start of the pandemic in addition to personality types. Results showed that an individual's level of extraversion correlated with an increase in anxiety levels [F(2,116) = 4.720, p = 0.011, np2=.075], but level of neuroticism level [F(2,117) = 0.878, p = 0.433)] did not. These findings have implication for other isolation situations, in which a person's personality traits could help to predict how their mental health may be affected by a future pandemic or social isolation.

Of each of the Big-Five personality traits, neuroticism is most strongly associated with poor relationship outcomes. Prior research has established a robust negative association between neuroticism and relationship quality, regardless of participant age, length of relationship, and country of origin. As so much has already been studied on the topic of neuroticism and relationship quality, the current study explores the association between neuroticism and relationship using meta-analytic methodology, and details whether Hill's seven criteria for causation have been met in the current literature thus far. After searching through databases and the references of included studies, I used 151 published studies that reported an effect size between neuroticism and relationship quality. Reported effect sizes included an overall aggregate correlation of -.222, and differentiated effect sizes for male actor and partner correlations, and female actor and partner correlations. I used two-way tests to explore if the sample country of origin, type of measure used, and whether the effect size was cross-sectional or longitudinal moderated the -.222 association. Further, I used meta-regression to test whether the length of relationship or participant age moderated the association. Results showed that sample country of origin and participant age did not moderate the association, suggesting that neuroticism and relationship quality are similarly associated regardless of where a participant was from or their age. However, longitudinal data showed a stronger negative relationship than cross-sectional data, measures of depression and anxiety demonstrated a stronger negative relationship than broad neuroticism measures, and a greater time spent in a relationship showed a weaker relationship between the two variables. Results are discussed in light of the interpersonal and intrapersonal models of neuroticism and the social exchange theory, and a model for how neuroticism operates through emotions, interpretations and behaviors is outlined. This model offers information for ways a couples' therapist could work to mitigate the association between neuroticism and relationship quality. A case for causation could not be established, so future directions for the field are delineated.
