The fading affect bias (FAB) occurs when unpleasant affect fades faster than pleasant affect. To detect mechanisms that influence the FAB in the context of death, we measured neuroticism, depression, anxiety, negative religious coping, death attitudes, and complicated grief as potential predictors of FAB for unpleasant/death and pleasant events at 2 points in time. The FAB was robust across older and newer events, which supported the mobilization-minimization hypothesis. Unexpectedly, complicated grief positively predicted FAB, and death avoidant attitudes moderated this relation, such that the Initial Event Affect by Grief interaction was only significant at the highest 3 quintiles of death avoidant attitudes...

Most road accidents are caused by human factors alone or in combination with other factors. Deficits in driving skill are a human factor that contributes to accidents. It is important to focus on driving skills to reduce traffic accidents and enhance safe driving. In this study, we adopted a Chinese version of the Driver Skill Inventory (DSI) and explored its correlation with driving behaviors, sociodemographic factors and personality. A total of 295 licensed drivers voluntarily completed a survey that covered the DSI, the Driver Behavior Questionnaire, the Positive Driver Behavior Scale, self-reported traffic accidents, penalty points and fines, the Big Five Inventory, and sociodemographic parameters...

The current study aimed to conceptually replicate previous studies on the effects of actor personality, partner personality, and personality similarity on general and relational well-being by using response surface analyses and a longitudinal sample of 4,464 romantic couples. Similar to previous studies using difference scores and profile correlations, results from response surface analyses indicated that personality similarity explained a small amount of variance in well-being as compared with the amount of variance explained by linear actor and partner effects...

Purpose: Medical students' personality traits, emotion regulation strategies, and empathic behavior are considered powerful predictors for their future achievements, professional adjustment, and mental strength. Coping strategies such as "self-blame," "rumination," "catastrophizing," "blaming others," lack of empathy, decreased emotion recognition abilities, and neuroticism are maladaptive and, thus, less desirable traits in medical professionals...

Whilst associations between polygenic risk scores (PRSs) for schizophrenia and various phenotypic outcomes have been reported, an understanding of developmental pathways can only be gained by modelling comorbidity across psychopathology. We examine how genetic risk for schizophrenia relates to adolescent psychosis-related and internalizing psychopathology using a latent modelling approach, and compare this to genetic risk for other psychiatric disorders, to gain a more comprehensive understanding of the developmental pathways at this age...

Anorexia nervosa (AN) and obsessive-compulsive disorder (OCD) are often comorbid and likely to share genetic risk factors. Hence, we examine their shared genetic background using a cross-disorder GWAS meta-analysis of 3495 AN cases, 2688 OCD cases, and 18,013 controls. We confirmed a high genetic correlation between AN and OCD (rg  = 0.49 ± 0.13, p = 9.07 × 10-7 ) and a sizable SNP heritability (SNP h2  = 0.21 ± 0.02) for the cross-disorder phenotype. Although no individual loci reached genome-wide significance, the cross-disorder phenotype showed strong positive genetic correlations with other psychiatric phenotypes (e...

Although neuroticism is the strongest personality predictor of sleep disturbance, it is not clear whether dysphoric (Withdrawal) or angry (Volatility) aspect of neuroticism is more important and whether problematic technology use plays an intervening role. To this end, this study examined distinct contributions of neurotic withdrawal and volatility in predicting self-reported sleep disturbance while testing the mediating role of problematic internet use. Methods: One-hundred and fourty-three college students completed an online survey that included measures of neuroticism, sleep quality, and problematic internet use...

The present study examined the relationship between social capital and depressive symptoms and the moderating role of the Big Five personality constructs in a national sample of African American adults. Data were collected from a national probability sample of 803 African American men and women using a telephone survey including measures of the Big Five personality traits, social capital, and depressive symptomatology. Most interestingly, there was evidence for Personality X Social Capital interactions on depressive symptoms...

Subjective wellbeing (SWB) has been widely accepted as one of the most important elements of successful ageing. The present study explores the impact of two well-established correlates of SWB: physical activity and personality. Physical activity and each of the Big Five personality traits are consistent predictors of SWB, but there has been little research on whether certain personality traits enhance or hinder the psychological benefits of physical activity in older adults. This study examines the interactions of leisure-time physical activity and personality traits on SWB, and whether such interactions vary between older adults in Hong Kong (HK) and older adults in the United Kingdom (UK)...

Reports an error in "Divergent personality structures of brown ( Sapajus apella ) and white-faced capuchins ( Cebus capucinus )" by Lauren M. Robinson, F. Blake Morton, Marieke C. Gartner, Jane Widness, Annika Paukner, Jennifer L. Essler, Sarah F. Brosnan and Alexander Weiss ( Journal of Comparative Psychology , 2016[Nov], Vol 130[4], 305-312). In the article, there is an error in several of the Tables in the Results. The coefficients related to Attentiveness were unintentionally reversed-scored. As these associations were not significant, this error had no effect on the interpretation of the results...

The present study aimed to identify whether polygenic scores (PGSs) for education, health and psychological factors are related to subjective age in a large sample of older adults. Participants were 7,763 individuals of European ancestry (57% women, Mean age = 69.15, SD = 10.18) from the Health and Retirement Study who were genotyped and provided subjective age data. Higher PGSs for educational achievement and well-being were related to a younger subjective age, whereas higher PGSs for neuroticism, body mass index, waist circumference, and depressive symptoms were associated with an older subjective age...

Childhood maltreatment history is a prevalent risk factor for substance use disorder and has lifelong adverse consequences on psychiatric wellbeing. The role of personality variations in determining childhood maltreatment-associated outcomes is poorly understood. This study sought to test neuroticism and agreeableness as mediator and moderator, respectively, of functional outcomes associated with having a history of childhood maltreatment and presence/absence of cocaine dependence. Ninety-four participants completed the Structured Clinical Interview for DSM-IV (SCID-IV), Childhood Trauma Questionnaire (CTQ), NEO-Five Factor Inventory (NEO-FFI), and the Addiction Severity Index (ASI)...

Several recent studies have demonstrated the association of cat-related injuries with major depression and with depressiveness in the general population. It was suggested that cat-scratch disease, the infection with the bacterium Bartonella henselae , can be responsible for the observed association. However, no direct evidence for the role of the Bartonella infection in this association has been published until now. In this preregistered case-controls study performed on 250 healthy subjects tested earlier for the presence of anti- Toxoplasma IgG antibodies, we searched for the positive association between presence of anamnestic anti- Bartonella IgG antibodies and depressiveness measured with Beck II inventory, depression subscale of neuroticism measured with N-70 questionnaire, and self-reported health problems...

Metaphors frequently link negative affect with darkness and associations of this type have been established in several experimental paradigms. Given the ubiquity and strength of these associations, people who prefer dark to light may be more prone to negative emotional experiences and symptoms. A five study investigation (total N = 605) couches these ideas in a new theoretical framework and then examines them. Across studies, 1 in 4 people preferred the perceptual concept of dark over the perceptual concept of light...
