OBJECTIVE
Somatic symptom and related disorders (SSRD) are often complicated by cognitive symptoms, including reduced information processing speed, memory, and planning. Depression has been related to poor cognitive functioning in SSRD, but the role of underlying personality factors is poorly understood. This study investigates the association between personality factors (neuroticism, extraversion, openness, agreeableness, and conscientiousness) with cognitive functioning in patients with SSRD.
METHODS
Data from 366 patients with SSRD from a tertiary care expert center (mean age = 42.1 years (SD = 13.4), 59.6% women) were analyzed using a cross-sectional design. Neuropsychological assessments included measures of information processing speed, memory, attention, and executive function. Personality factors were assessed using the NEO-FFI and depressive symptoms using the PHQ-9.
RESULTS
Regression analyses showed associations between neuroticism with poorer performance on visual memory (B = -0.09, SE = 0.04, β = -0.14, p = .019), and planning (B = -0.09. SE = 0.02, β = -0.23, p < .001). Extraversion was also inversely associated with visual memory (B = -0.13, SE = 0.05, β = -0.18, p = .011) and planning (B = -0.07, SE = 0.03, β = -0.17, p = .021) and openness was associated with better visual memory (B = 0.17, SE = 0.05, β = 0.19, p = .002). These associations were attenuated but remained significant after adjusting for depressive symptoms.
CONCLUSION
Neuroticism, extraversion, and low openness were associated with lower cognitive functioning (particularly planning and visual memory) in patients with SSRD, which remained significant after taking depressive symptoms into account.

BACKGROUND
A growing body of evidence has shown that maladaptive traits and emerging patterns of personality can be traced to an early stage of development and may be assessed in childhood. The goal of present study was to provide preliminary data on the validity of the Coolidge Personality and Neuropsychological Inventory for Children (CPNI), an instrument designed to assess personality pathologies and other clinical conditions in childhood.
METHOD
A sample of 146 clinicians completed the CPNI, as well as the Child Behavior Checklist (CBCL) to evaluate the behavioral problems and social competencies, regarding a child (aged 6-11 years) who had been in their care between 2 and 12 months. The clinicians also filled out a clinical questionnaire to provide information on the children, their families, and psychotherapies.
RESULTS
There were significant and clinically consistent associations between the CPNI and CBCL. They confirmed the good concurrent (convergent and discriminant) validity of the CPNI.
CONCLUSIONS
The findings seem to support the validity of the CPNI as diagnostic instrument, taking children's PDs and behavioral problems into account. Despite some limitations, the CPNI represents a helpful measure to evaluate the children's personality configurations according to the DSM model. It may be employed along with other tools based on other diagnostic frameworks within the context of a multi-method and multi-informant assessment to provide an accurate and comprehensive formulation of children's overall functioning.

Given the paucity of research examining relationships between mindfulness and specific facets of personality, we conducted detailed analyses to explore associations between personality facets, dispositional mindfulness, and health. Overall, 781 participants completed the Five Factor Mindfulness Questionnaire (FFMQ), the Big Five Inventory-2 (BFI-2) to measure personality factors and facets, and the RAND 36-Item Health Survey 1.0 (RAND-36). As expected, BFI-2 factors and facets and FFMQ subscales, except Observing, were consistently correlated. Canonical correlations of BFI-2 facets and FFMQ subscales provided two statistically significant functions. Function 1, Self-Regulation, included FFMQ Acting with Awareness, Non-Judging, and Non-Reacting, as well as BFI-2 Negative Emotionality (Anxiety, Depression, Emotional Volatility), Conscientiousness (Productiveness, Responsibility), and Extraversion (Assertiveness, Energy). Function 2, Self-Awareness, comprised of FFMQ Describing and Observing, and all facets of Open-Mindedness. A latent profile analysis produced three latent profiles: Self-Regulation was defined by higher FFMQ subscales as well as higher Extraversion (all facets), Agreeableness (all facets), Conscientiousness (all facets), and lower Negative Emotionality (all facets); Self-Dysregulation was defined by lower scores on most FFMQ subscales, BFI-2 Extraversion facet scores, Agreeableness (Trust), Conscientiousness (Productiveness), and higher Negative Emotionality facets; and, an Average profile included midrange levels of mindfulness and personality facets. Further, there were statistically significant differences in RAND-36 physical and psychological health based on the latent profiles. The novel findings examining the facet-level relationship between personality and mindfulness contribute to prior inconclusive literature. These results presenting a nuanced understanding of the association between dispositional mindfulness and personality provide preliminary information suggesting that self-regulation can affect health.

BACKGROUND
Personality and coping may be related to symptom severity and psychosocial functioning in patients with recent-onset psychosis. This study aimed to investigate associations of personality traits and coping strategies with concurrent and follow-up symptom severity and functioning in those patients, and identify whether coping mediates relations between personality and symptoms or functioning.
METHODS
At baseline, 527 recent-onset psychosis patients (73 % male, mean age = 28 years) received assessments on personality (Neuroticism-Extraversion-Openness - Five-Factor Inventory), coping (Utrecht Coping List), symptom severity (Positive And Negative Syndrome Scale) and psychosocial functioning (Global Assessment of Functioning Scale). Of those, 149 also received symptom and functioning assessments at follow-up. Multivariable linear regression analyses were performed to assess cross-sectional associations of personality and coping with symptoms and functioning at baseline. Longitudinal associations of baseline personality and coping with follow-up symptomatic remission and functioning were analyzed with multivariable linear and binary logistic regression analyses, respectively. Lastly, it was investigated whether coping mediated associations between personality and symptoms or functioning.
RESULTS
Higher baseline Agreeableness (B = -0.019, [95%CI: -0.031; -0.007]) and Neuroticism (B = -0.017, [95%CI: -0.028; -0.006]) were associated with lower concurrent symptom severity. Reassuring Thoughts were associated with better functioning at baseline (B = 0.833, [95%CI: 0.272; 1.393]). Neither personality nor coping were associated with follow-up symptomatic remission or functioning. Coping did not mediate associations between personality and symptoms or functioning.
CONCLUSION
Only the coping strategy Reassuring Thoughts is associated with better baseline functioning in patients with recent-onset psychosis. Personality traits seem to have limited clinically relevant relations with symptom severity or functioning.

OBJECTIVE
Frequent nightmare behavior or deep nightmare experiences may harm the physical and mental health and performance of athletes. This study explores the nightmare experiences of athletes, and includes non-athletes with similar experiences for comparison.
METHODS
The Nightmare Experience Questionnaire (NEQ); Zuckerman-Kuhlman-Aluja Personality Questionnaire, Shortened Form (ZKA-PQ/SF); and Self-Rating Anxiety Scale (SAS) were used. The subjects were 187 athletes (mean age = 20.44 years, SD = 0.85; 91 females, 96 males) and 90 non-athletes (mean age = 20.34 years, SD = 1.65; 52 females, 38 males) who reported having nightmares.
RESULTS
A total of 87 athletes (46.5%) reported having nightmare experiences. The athlete nightmare group scored significantly higher in neuroticism than the non-nightmare group, and their anxiety scores were significantly higher than those of non-athletes, who scored higher in aggressiveness, neuroticism, and sensation seeking. Moreover, anxiety, neuroticism, and sensation seeking positively predicted athletes' nightmare experiences.
CONCLUSIONS
Personality traits and anxiety levels can be effectively applied to predict athletes' nightmare experiences.

As COVID-19 vaccines' accessibility has grown, so has the role of personal choice in vaccination, and not everybody is willing to vaccinate. Exploring personality traits' associations with vaccination could highlight some person-level drivers of, and barriers to, vaccination. We used self- and informant-ratings of the Five-Factor Model domains and their subtraits (a) measured approximately at the time of vaccination with the 100 Nuances of Personality (100NP) item pool (N = 56,575) and (b) measured on average ten years before the pandemic with the NEO Personality Inventory-3 (NEO-PI-3; N = 3,168). We tested individual domains' and either items' (in the 100NP sample) or facets' (in the NEO-PI-3 sample) associations with vaccination, as well as their collective ability to predict vaccination using elastic net models trained and tested in independent sample partitions. Although the NEO-PI-3 domains and facets did not predict vaccination ten years later, the domains correlated with vaccination in the 100NP sample, with vaccinated people scoring slightly higher on neuroticism and agreeableness and lower on openness, controlling for age, sex, and education. Collectively, the five domains predicted vaccination with an accuracy of r = .08. Associations were stronger at the item level. Vaccinated people were, on average, more science-minded, politically liberal, respectful of rules and authority, and anxious but less spiritual, religious, and self-assured. The 100NP items collectively predicted vaccination with r = .31 accuracy. We conclude that unvaccinated people may be a psychologically heterogeneous group and highlight some potential areas for action in vaccination campaigns.

Social anxiety disorder (SAD) can come in different forms, presenting problems for diagnostic classification. Here, we examined personality traits in a large sample of patients (N = 265) diagnosed with SAD in comparison to healthy controls (N = 164) by use of the Revised NEO Personality Inventory (NEO-PI-R) and Karolinska Scales of Personality (KSP). In addition, we identified subtypes of SAD based on cluster analysis of the NEO-PI-R Big Five personality dimensions. Significant group differences in personality traits between patients and controls were noted on all Big Five dimensions except agreeableness. Group differences were further noted on most lower-order facets of NEO-PI-R, and nearly all KSP variables. A logistic regression analysis showed, however, that only neuroticism and extraversion remained significant independent predictors of patient/control group when controlling for the effects of the other Big Five dimensions. Also, only neuroticism and extraversion yielded large effect sizes when SAD patients were compared to Swedish normative data for the NEO-PI-R. A two-step cluster analysis resulted in three separate clusters labelled Prototypical (33%), Introvert-Conscientious (29%), and Instable-Open (38%) SAD. Individuals in the Prototypical cluster deviated most on the Big Five dimensions and they were at the most severe end in profile analyses of social anxiety, self-rated fear during public speaking, trait anxiety, and anxiety-related KSP variables. While additional studies are needed to determine if personality subtypes in SAD differ in etiological and treatment-related factors, the present results demonstrate considerable personality heterogeneity in socially anxious individuals, further underscoring that SAD is a multidimensional disorder.

Tests of statistical interactions (or tests of moderation effects) in personality disorder research are a common way for researchers to examine nuanced hypotheses relevant to personality pathology. However, the nature of statistical interactions makes them difficult to reliably detect in many research scenarios. The present study used a flexible, simulation-based approach to estimate statistical power to detect trait-by-trait interactions common to psychopathy research using the Triarchic model of Psychopathy and the Psychopathic Personality Inventory. Our results show that even above-average sample sizes in these literatures (e.g., = 428) provide inadequate power to reliably detect trait-by-trait interactions, and the sample sizes needed to detect interaction effect sizes in realistic scenarios are extremely large, ranging from 1,300 to 5,200. The implications for trait-by-trait interactions in psychopathy are discussed, as well as how the present findings might generalize to other areas of personality disorder research. We provide recommendations for how to design research studies that can provide informative tests of interactions in personality disorder research, but also highlight that a more realistic option is to abandon the traditional approach when testing for interaction effects and adopt alternative approaches that may be more productive.

PURPOSE
Personality functioning is strongly linked to well-being in the general population. Yet, there is a lack of scientific knowledge about the pathways between personality trait facets and emotional, psychological and social well-being in ED patients. The general aim was to examine potential associations between maladaptive personality trait facets and the three main dimensions of well-being.
METHODS
Participants were 1187 female eating disorder patients who were referred for specialized treatment. Patients were diagnosed with anorexia nervosa (31.7%), bulimia nervosa (21.7%), binge eating disorder (11%) and other specified eating disorders (35.5%). The Personality Inventory for the DSM 5 (PID-5) was used to measure 25 trait facets, and well-being was measured with the Mental Health Continuum Short Form (MHC-SF). Multiple hierarchical regression analyses were applied to examine potential associations between personality and well-being while controlling for background and illness characteristics.
RESULTS
Personality trait facets led to a statistically significant increase of the explained variance in emotional (38%), psychological (39%), and social well-being (26%) in addition to the background and illness characteristics. The personality trait facets anhedonia and depression were strongly associated with all three well-being dimensions.
CONCLUSION
Personality traits may play an essential role in the experience of well-being among patients with EDs. To promote overall mental health, it may be critical for clinicians to address relevant personality trait facets, such as anhedonia and depression, associated with well-being in treatment.

Review
PURPOSE OF REVIEW
Childhood trauma is an important risk factor for the development of personality disorders (PDs), yet most research has been devoted to categorical models of personality pathology. Considering the introduction of a dimensional PD model with ICD-11, we review current findings related to various forms of childhood trauma, and PDs, operationalized in the form of personality functioning and maladaptive traits. We focus on the magnitude of associations and examine specific relationships between emotional and physical trauma with areas of personality functioning and single traits.
RECENT FINDINGS
Two studies showed a strong association between childhood trauma and personality dysfunction. Seven studies, including clinical and forensic samples, demonstrated heterogeneous associations between various forms of childhood trauma and maladaptive traits. Overall, four studies indicated a slightly stronger association between personality dysfunction, maladaptive trait expression, and higher levels of emotional trauma than for physical or sexual trauma. Regarding specific trait domains and childhood trauma, most studies yielded the strongest associations for either psychoticism or detachment. Research on childhood trauma and dimensional PD models (i.e., personality functioning and traits) has the potential to contribute to a better understanding of their complex relationship. However, high intercorrelations among different types of childhood trauma, areas of personality functioning, and trait domains increase the difficulty of disentangling single effects. More research is needed including clinical and non-Western samples, especially considering the upcoming ICD-11 classification.
