Meta-Analysis
OBJECTIVE
To examine the association between Five-Factor Model personality traits and grip strength.
METHOD
Adults aged 16 to 104 years old (N > 40,000) were from the Health and Retirement Study, the Midlife in the United States Study, The English Longitudinal Study of Aging, the National Health and Aging Trends Survey, the United Kingdom Household Longitudinal Study, and the Wisconsin Longitudinal Study graduate and sibling samples. Participants had data on personality traits, demographic factors, grip strength, and mediators such as depressive symptoms, physical activity, body mass index (BMI), and c-reactive protein (CRP).
RESULTS
Across all samples and a meta-analysis, higher neuroticism was related to lower grip strength (meta-analytic estimate: -0.07, 95%CI: -0.075; -0.056). Higher extraversion (0.04, 95%CI: 0.022; 0.060), openness (0.05, 95%CI: 0.032; 0.062), and conscientiousness (0.05, 95%CI: 0.04; 0.065) were associated with higher grip strength across most samples and the meta-analysis. Depressive symptoms were the most consistent mediators between neuroticism and grip strength. Depressive symptoms and physical activity partly mediated the associations with extraversion, openness, and conscientiousness. Lower CRP partly mediated the association with conscientiousness. Sex moderated the associations for extraversion, openness, and conscientiousness, with stronger associations among males. Age moderated the neuroticism association, with stronger associations among younger individuals.
CONCLUSION
This study provides replicable evidence that personality is related to grip strength and identifies potential moderators and mediators of these associations. Overall, higher neuroticism is a risk factor for low grip strength, whereas high extraversion, openness, and conscientiousness may be protective.

There are substantive theoretical questions about whether personal affect romantic relationship functioning. The current research tested the association between personal values and romantic relationship quality while considering potential mediating mechanisms related to pro-relational attitudes, communal strength, intrinsic relationship motivation, and entitlement. Across five studies using different measures of value priorities, we found that the endorsement of self-transcendence values (i.e., benevolence, universalism) was related to higher romantic relationship quality. The findings provided support for the mediating roles of pro-relational attitudes, communal strength, and intrinsic relationship motivation. Finally, a dyadic analysis in our fifth study showed that self-transcendence values mostly influence a person's own relationship quality but not that of their partner. These findings provide the first evidence that personal values are important variables in romantic relationship functioning while helping to map the mechanisms through which this role occurs.

BACKGROUND AND OBJECTIVES
Concerns about early childhood social transitions among transgender youth include that these youth may later change their gender identification (ie, retransition), a process that could be distressing. The current study aimed to provide the first estimate of retransitioning and to report the current gender identities of youth an average of 5 years after their initial social transitions.
METHODS
The current study examined the rate of retransition and current gender identities of 317 initially transgender youth (208 transgender girls, 109 transgender boys; M = 8.1 years at start of study) participating in a longitudinal study, the Trans Youth Project. Data were reported by youth and their parents through in-person or online visits or via e-mail or phone correspondence.
RESULTS
We found that an average of 5 years after their initial social transition, 7.3% of youth had retransitioned at least once. At the end of this period, most youth identified as binary transgender youth (94%), including 1.3% who retransitioned to another identity before returning to their binary transgender identity. A total of 2.5% of youth identified as cisgender and 3.5% as nonbinary. Later cisgender identities were more common among youth whose initial social transition occurred before age 6 years; their retransitions often occurred before age 10 years.
CONCLUSIONS
These results suggest that retransitions are infrequent. More commonly, transgender youth who socially transitioned at early ages continued to identify that way. Nonetheless, understanding retransitions is crucial for clinicians and families to help make retransitions as smooth as possible for youth.

BACKGROUND
The challenging nature of performing surgery on a personal and professional level demands specific characteristics. Personality traits play an important role in the nature and behavior of humans, which are studied using the five-factor model. Therefore, we investigated the personality of 3 surgical generations.
METHODS
Three distinct surgical populations were approached. The Dutch Big Five Inventory-2 was sent out online to 126 surgical residents (response: n = 69) and 104 surgeons (response: n = 60) in a teaching region in the Netherlands. Moreover, medical students interested in surgery were approached via the students' surgical society (response: n = 54). To obtain a normative Dutch population sample, the Longitudinal Internet studies for the Social Sciences panel was used, creating groups of the following age categories: 18 to 25 (n = 84), 26 to 35 (n = 101), 36 to 67 (n = 432). One-way analysis of variance with Bonferroni correction was used to assess differences in personality scores.
RESULTS
Individuals interested in surgery (ie, surgically-oriented medical students, surgical residents, and surgeons) generally scored significantly higher on extraversion, conscientiousness, agreeableness, open-mindedness, and lower on negative emotionality compared with the normative population sample. Across the surgical generations, surgical residents scored significantly lower on open-mindedness (3.60) compared with surgeons (3.92) and surgically-oriented medical students (3.82). Surgically-oriented medical students scored significantly higher in negative emotionality (2.44) compared with surgical residents (2.12) and surgeons (2.07).
CONCLUSION
Being a surgeon demands particular levels of determination and emotional stability. The surgical population shows a distinct personality pattern compared with the normative population, and more modest differences exist between persons in different stages of their surgical career.

BACKGROUND
Sexual orientation refers to a person's enduring emotional, romantic, or sexual attractions to other people. Sexual orientation measures do not typically consider desires for, or sexual behavior with, transgender people. We describe measures inclusive of transgender people and characterize sexual orientation identity, behavior, and attraction in a representative sample of the U.S. transgender population.
METHODS
Between April 2016-December 2018, a U.S. national probability sample of transgender (n = 274) and cisgender (n = 1,162) adults were invited to complete a self-administered web or mailed paper survey. We assessed sexual identity with updated response options inclusive of recent identity terms (e.g., queer), and revised sexual behavior and attraction measures that included transgender people. Multiple response options were allowed for sexual behavior and attraction. Weighted descriptive statistics and sexual orientation differences by gender identity groups were estimated using age-adjusted comparisons.
RESULTS
Compared to the cisgender population, the transgender population was more likely to identify as a sexual minority and have heterogeneity in sexual orientation, behavior, and attraction. In the transgender population, the most frequently endorsed sexual orientation identities were "bisexual" (18.9%), "queer" (18.1%), and "straight" (17.6%). Sexually active transgender respondents reported diverse partners in the prior 5 years: 52.6% cisgender women (CW), 42.7% cisgender men (CM), 16.9% transgender women (TW), and 19.5% transgender men (TM); 27.7% did not have sex in the past 5 years. Overall, 73.6% were "somewhat"/ "very" attracted to CW, 58.3% CM, 56.8% TW, 52.4% TM, 59.9% genderqueer/nonbinary-females-at-birth, 51.9% genderqueer/nonbinary-males-at-birth. Sexual orientation identity, behavior, and attraction significantly differed by gender identity for TW, TM, and nonbinary participants (all p < 0.05).
CONCLUSIONS
Inclusive measures of sexual orientation captured diverse sexual identities, partner genders, and desires. Future research is needed to cognitively test and validate these measures, especially with cisgender respondents, and to assess the relation of sexual orientation and health for transgender people.

BACKGROUND
Zuckerman-Kuhlman-Aluja Personality questionnaire (ZKA-PQ) measures five psychobiologically based personality factors (activity, aggression, extraversion, neuroticism, and sensation seeking). The inner strength (from the ten perfections based on Theravada Buddhism) deems positive character, which includes truthfulness, perseverance, wisdom, generosity, morality (five precepts), mindfulness and meditation, patience and endurance, equanimity, determination, and loving kindness measured by the strength-based inventory (SBI). Our aim was to unfold the relationship between ZKA factors and SBI.
METHODS
642 Thai (age mean = 28.27, SD = 10.61) individuals (males 26.2%, females 73.8%) filled out our questionnaire battery: (1) Zuckerman-Kuhlman-Aluja Personality questionnaire - 200 items, 20 facets, five factors: Aggressiveness, Sensation Seeking, Activity, Extraversion, Neuroticism. (Cronbach alphas: 0.88, 0.81, 0.83, 0.89, 0.91 for AG, SS, AC, EX, NEU, respectively). (2) Strength-based inventory - 10 items, measuring 10 inner strength (Cronbach alpha: 0.68). Pearson correlation, neural network modelling and person-oriented methodology (model-based clustering) were conducted for analysis.
RESULTS
Our correlational results revealed that inner strengths are negatively related to Aggression (r=-0.44**), Neuroticism (r=-0.43**), Sensation seeking (r=-0.16**), whereas positively related to Extraversion (r=0.37**) and Activity (r=0.24**). Highest correlations were found between AG and patience (-0.43**) and NEU and perseverance (r=-0.40**), both with negative sign. According to neural network modelling Activity was most related to Perseverance, Aggression to lack of Patience, Neuroticism to lack of Perseverance and Equanimity, Sensation Seeking to lack of Morality. Extraversion was most weakly related to inner strengths, but it was related to all other personality dimensions. Model based clustering revealed four typical personality profiles: resilients (41.8%), extraverted undercontrollers (29.0%), introverted undercontrollers (10.6%) and overcontrolled (18.6%). Results showed that resilients had highest inner strength levels, whereas overcontrolled ones had the lowest.
CONCLUSION
Negative traits are, as expected, conversely related with strength, while positive traits (extraversion and activity) are positively related with strength. Our results confirm that resilient personality pattern can be linked to the inner strengths measured by SBI scale, which was based on 10 Buddhist perfections. Further results should be addressed how increase in inner strength can be related to changes in biologically based personality dimensinos towards the resilient pattern.

Neuroticism is one of the major traits describing human personality, and a predictor of mental and physical disorders with profound public health significance. Individual differences in emotional variability are thought to reflect the core of neuroticism. However, the empirical relation between emotional variability and neuroticism may be partially the result of a measurement artifact reflecting neuroticism's relation with higher mean levels-rather than greater variability-of negative emotion. When emotional intensity is measured using bounded scales, there is a dependency between variability and mean levels: at low (or high) intensity, it is impossible to demonstrate high variability. As neuroticism is positively associated with mean levels of negative emotion, this may account for the relation between neuroticism and emotional variability. In a metaanalysis of 11 studies ( = 1,205 participants; 83,411 observations), we tested whether the association between neuroticism and negative emotional variability was clouded by a dependency between variability and the mean. We found a medium-sized positive association between neuroticism and negative emotional variability, but, when using a relative variability index to correct for mean negative emotion, this association disappeared. This indicated that neuroticism was associated with experiencing more intense, but not more variable, negative emotions. Our findings call into question theory, measurement scales, and data suggesting that emotional variability is central to neuroticism. In doing so, they provide a revisionary perspective for understanding how this individual difference may predispose to mental and physical disorders.

PloS One 2023This scoping review explores the characteristics of a meaningful life appraised by adults living with an acquired neurological impairment. (Review)
Review
OBJECTIVE
This scoping review explores the characteristics of a meaningful life appraised by adults living with an acquired neurological impairment.
INTRODUCTION
Limitations in function, activity or participation following a neurological injury or disease imposes comprehensive changes on the every-day life of the affected person and close relatives. Including patients' perception of a meaningful life is pivotal to facilitate motivation and individualize rehabilitation efforts to address the patients' wishes, hopes, needs, and preferences. Surprisingly, only little research has been devoted to illuminating what a meaningful life is from the impaired person's perspective. Hence, a scoping review of existing knowledge is needed to facilitate person-centered high-quality rehabilitation and research initiatives.
INCLUSION CRITERIA
All studies, published in English or Scandinavian languages describing a meaningful life as experienced by adult persons with neurological impairment were included. No search date range filter was selected.
METHODS
This review followed the Joanna Briggs Institute (JBI) methodology for scoping reviews according to a published protocol. A three-step search strategy was conducted in the databases PubMed, Cinahl, PsycINFO and Embase. At least two independent researchers conducted inclusions and exclusions, data extraction, and analyses. Covidence software was used to manage the information.
FINDINGS
We identified 307 studies. Of these, 20 were included and quality assessed. Findings are reported in accordance with the PRISMA- SCR checklist and descriptively presented mapped in three main domains and 10 ten sub-domains.
CONCLUSION
Current literature conveys no clear definition or perception of what a meaningful life is. However, across the 20 included studies, the following main characteristics were stepped forward as particularly significant for adults living with an acquired neurological impairment in regard to achieving a meaningful life: i) to be part of meaningful relationships and meaningful activities; ii) to become confident with one's perceived identity.

Our God image not only determines the nature of our relationship with God, it also influences our personality, actions, self-concept, mindset and social relations. It acts within and through us. Although everyone has a God image - regardless of whether one is a believer or not - the ways in which we experience God's relation to us are manifold. It is not unusual that even believers of the same congregation give accounts of diverse God images. Schema is a widely used term in psychology. Schemas describe cognitive structures that filter, encode and interpret the stimuli affecting the person. They can influence the perception of reality, which later impacts the behavior and mood of the individual and in severe cases can result in pathology. The factors influencing the God image and early maladaptive schemas both have proven roots in early childhood and are impacted by the child-parent relationship. Our research focuses on examining the connection between maladaptive schemas and the God image and their relation to parental influence.

Review
The human brain's resting-state functional connectivity (rsFC) provides stable trait-like measures of differences in the perceptual, cognitive, emotional, and social functioning of individuals. The rsFC of the prefrontal cortex is hypothesized to mediate a person's rational self-government, as is also measured by personality, so we tested whether its connectivity networks account for vulnerability to psychosis and related personality configurations. Young adults were recruited as outpatients or controls from the same communities around psychiatric clinics. Healthy controls (n = 30) and clinically stable outpatients with bipolar disorder (n = 35) or schizophrenia (n = 27) were diagnosed by structured interviews, and then were assessed with standardized protocols of the Human Connectome Project. Data-driven clustering identified five groups of patients with distinct patterns of rsFC regardless of diagnosis. These groups were distinguished by rsFC networks that regulate specific biopsychosocial aspects of psychosis: sensory hypersensitivity, negative emotional balance, impaired attentional control, avolition, and social mistrust. The rsFc group differences were validated by independent measures of white matter microstructure, personality, and clinical features not used to identify the subjects. We confirmed that each connectivity group was organized by differential collaborative interactions among six prefrontal and eight other automatically-coactivated networks. The temperament and character traits of the members of these groups strongly accounted for the differences in rsFC between groups, indicating that configurations of rsFC are internal representations of personality organization. These representations involve weakly self-regulated emotional drives of fear, irrational desire, and mistrust, which predispose to psychopathology. However, stable outpatients with different diagnoses (bipolar or schizophrenic psychoses) were highly similar in rsFC and personality. This supports a diathesis-stress model in which different complex adaptive systems regulate predisposition (which is similar in stable outpatients despite diagnosis) and stress-induced clinical dysfunction (which differs by diagnosis).
