INTRODUCTION: Aim of the present study was to assess personality and psychopathological characteristics in patients with functional movement disorders (FMDs) compared to patients with other neurological disorders (OND). METHODS: In this cross-sectional study, patients affected by clinically established FMDs and OND who attended the Neurologic Unit of the University-Hospital "Policlinico-San Marco" of Catania from the 1st of December 2021 to the 1st of June 2023 were enrolled. Personality characteristics were assessed with the Rorschach test coded according to Exner's comprehensive system and the Structured Clinical Interview for DSM-5 (SCID-II). RESULTS: Thirty-one patients with FMDs (27 women; age 40.2±15.5 years; education 11.7±3.2 years; disease duration 2.3±2.5 years) and 24 patients affected by OND (18 women; age 35.8±16.3 years; education 11.9±2.9 years; disease duration 3.4±2.8 years) were enrolled. At the Rorschach, FMDs presented a significantly higher frequency of Popular (P) and sum of all Human content codes (SumH>5) responses and avoidant coping than OND. CONCLUSION: FMDs presented "conformity behaviors", excessive interest in others than usual a maladaptive avoidant style of coping and a difficulty in verbalizing emotional distress. These psychopathological characteristics may favor the occurrence of FMDs.

AIM: This study aimed to determine the effect of digital games on the creativity of adolescents. METHODS: This study was designed as a cross-sectional study using simple random sampling following the STROBE checklist. It was conducted with 384 adolescents between January and June 2022. Data were collected using the Digital Game Addiction Scale for Children and the Creative Personality Traits Scale. RESULTS: The adolescents were at risk for digital game addiction and had moderate creativity levels. The adolescents who had a male sex, had mothers who received primary education, started playing digital games before the age of 6 years, were using the internet for >5 h a day, had no activity other than playing digital games, and preferred action, adventure, and fighting games had higher digital game addiction levels than the other adolescents. In addition, the male adolescents had higher creativity levels than the female adolescents. There was a significant negative relationship between digital game addiction and creative personality traits among the adolescents. Digital game addiction had a negative effect on creativity. CONCLUSIONS: Adolescents are at risk for digital game addiction and have moderate creativity levels. Digital game addiction negatively affects the development of creative personality traits. Interventions should be planned to prevent digital game addiction among adolescents, and adolescents should be guided to increase awareness of the effects of digital games on their creativity.

Human performance applications of mindfulness-based training have demonstrated its utility in enhancing cognitive functioning. Previous studies have illustrated how these interventions can improve performance on traditional cognitive tests, however, little investigation has explored the extent to which mindfulness-based training can optimise performance in more dynamic and complex contexts. Further, from a neuroscientific perspective, the underlying mechanisms responsible for performance enhancements remain largely undescribed. With this in mind, the following study aimed to investigate how a short-term mindfulness intervention (one week) augments performance on a dynamic and complex task (target motion analyst task; TMA) in young, healthy adults (n = 40, age range = 18-38). Linear mixed effect modelling revealed that increased adherence to the web-based mindfulness-based training regime (ranging from 0-21 sessions) was associated with improved performance in the second testing session of the TMA task, controlling for baseline performance. Analyses of resting-state electroencephalographic (EEG) metrics demonstrated no change across testing sessions. Investigations of additional individual factors demonstrated that enhancements associated with training adherence remained relatively consistent across varying levels of participants' resting-state EEG metrics, personality measures (i.e., trait mindfulness, neuroticism, conscientiousness), self-reported enjoyment and timing of intervention adherence. Our results thus indicate that mindfulness-based cognitive training leads to performance enhancements in distantly related tasks, irrespective of several individual differences. We also revealed nuances in the magnitude of cognitive enhancements contingent on the timing of adherence, regardless of total volume of training. Overall, our findings suggest that mindfulness-based training could be used in a myriad of settings to elicit transferable performance enhancements.

Evidence links immune system alterations to major psychiatric disorders. The few previous studies on personality traits or personality disorders (PDs) indicate that immunometabolic dysregulation may be prevalent in this population. This study aimed to investigate relationships between personality traits, PDs, and immunometabolic markers in peripheral blood. We hypothesized that neuroticism would be correlated with elevated leptin. Participants were recruited as young adults seeking care for general psychiatric disorders. They responded to a personality inventory and were assessed for PDs, and reevaluated again at a 12 years follow-up. Blood samples were collected at the follow-up and analyzed for 29 immunometabolic markers. A positive correlation was found between the personality trait neuroticism and leptin (ρ = 0.31, p = 0.02). An exploratory analysis also revealed a positive correlation between brain-derived neurotrophic factor (ρ = 0.36, p < 0.01) and neuroticism. These findings remained after adjusting for other variables in general linear models. There were no relationships between PDs and any immunometabolic markers. Results both confirm previous findings of correlations between the immunometabolic system and personality traits and suggest directions for future research.

The current manuscript presents the convergence of the Dimensional Assessment of Personality Pathology (DAPP-BQ), using its short form the DAPP-90, and the Five-Factor Personality Inventory for International Classification of Diseases (ICD-11), the FFiCD, in the context of the five-factor personality model and the categorical approach of personality disorders (PDs). The current manuscript compares the predictive validity of both the FFiCD and the DAPP-90 regarding personality disorder scales and clusters. Results demonstrate a very high and meaningful convergence between the DAPP-90 and the FFiCD personality pathology models and a strong alignment with the FFM. The DAPP-90 and the FFiCD also present an almost identical predictive power of PDs. The DAPP-90 accounts for between 18% and 47%, and the FFiCD between 21% and 47% of PDs adjusted variance. It is concluded that both DAPP-90 and FFiCD questionnaires measure strongly similar pathological personality traits that could be described within the frame of the FFM. Additionally, both questionnaires predict a very similar percentage of the variance of personality disorders.

This study examines the influence of depressive personality styles on treatment responses in patients with major depression receiving cognitive behavioural therapy and psychodynamic therapy. We assessed changes in personality styles, including dependency, self-criticism, sociotropy, and autonomy, and their association with treatment response. Both treatment modalities led to significant reductions in self-criticism and sociotropy scores. Depressive symptom severity decreased overall, with a more pronounced reduction observed in the cognitive behavioural therapy group. Notably, reduced self-criticism and sociotropy were associated with better treatment outcomes in the cognitive behavioural therapy group. Our findings highlight the role of personality styles in influencing treatment outcomes for major depression. The study suggests an association between changes in personality styles and the reduction of symptoms. Our results support the idea that unique pathways of change are activated depending on the therapeutic intervention. These insights are critical in tailoring treatments to individual needs, addressing the central question of 'what works for whom'.

BACKGROUND: Resilience plays a crucial role in mental health promotion and prevention, and was shown to be more represented in individuals who exhibit high levels of extraversion, openness, agreeableness, and conscientiousness. However, there is a lack of studies that comprehensively investigate the association between personality traits and resilience in Lebanon and Arab countries more broadly. The purpose of the present study was to complement the literature by investigating the direct and indirect effects between the five personality traits and resilience among a sample of Lebanese adults through the intermediary role of posttraumatic growth. METHODOLOGY: A cross-sectional study was carried out between May and July 2022, and enrolled 387 participants, all aged above 18 years old and recruited from all Lebanon governorates. The questionnaire used included socio-demographic questions, and the following scales: Connor-Davidson Resilience Scale (CD-RISC) to assess resilience, post traumatic growth (PTG), and Big Five Inventory (BFI-2). The SPSS software v.25 was used for the statistical analysis. RESULTS: Post-traumatic growth mediated the association between extraversion / agreeableness / conscientiousness and resilience. Higher extraversion / agreeableness / conscientiousness was significantly associated with more post-traumatic growth. Higher post-traumatic growth was significantly associated with more resilience. Extraversion, but not agreeableness and conscientiousness, was significantly and directly associated with more resilience. CONCLUSION: Findings suggest that fostering PTG in individuals who experience adversity can help promote their resilience. Hence, it could be beneficial to design and apply programs aiming at supporting PTG among people who experience stressful and traumatizing situations, to consequently help them increase their sense of resilience.

Background: Suggestibility is a personality trait that reflects a general tendency to accept messages. The Multidimensional Iowa Suggestibility Scale (MISS) is a self-report scale developed to measure the degree of individuals' perceptions of their suggestibility. This study aimed to adapt the MISS in an Italian sample. Methods: We conducted two studies. In the first study, 345 subjects (270 females (78%), mean age = 36.21 years ± 14.06 SD) completed the translated Italian version of the MISS, composed of five subscales (consumer suggestibility; persuadability; sensation contagion; physiological reactivity; peer conformity). We investigated the structural validity of the scale through confirmatory factor analysis (CFA) testing four measurement models (unidimensional, four-factor, hierarchical four factors, and bifactor) and explored reliability in terms of internal consistency through the McDonald's omega. In the second study, we cross-validated the MISS on a new independent sample. We enrolled 277 participants (196 females (71%), mean age 30.56, SD = 12.58) who underwent the new version of the scale. We performed factor analyses to test structural validity and compared four measurement models. Then, we investigated reliability and conducted a latent variable analysis to explore divergent validity. Results: The CFA in the first study revealed a bifactor solution of the MISS. This structure was interpretable and provided an adequate fit for the data. The final version of the scale was reduced to forty-six items with globally good indices of adaptation. The scale also demonstrated acceptable reliability in terms of internal consistency through the McDonald's Hierarchical Omega. In the second study, we found that the bifactor structure was confirmed. Factor loadings inspection revealed that there was no justification to report only the separate scores for the subscales. We also found that the scale showed good internal consistency, but mixed evidence for divergent validity. Conclusions: In the end, the Italian version of the MISS demonstrated good psychometric properties which will be discussed in detail below.

Background: Chronic time pressure represents a prevalent concern within modern society, and effective measurement is crucial for research advancement. The Chronic Time Pressure Inventory (CTPI) has thus far demonstrated adequate psychometric properties. However, only two studies have examined the measure and evidence of its validity is limited. Accordingly, the current investigation, via two independent studies, assessed the factorial composition and validity (convergent/discriminant) of the CTPI. Methods: Study 1 (N = 398) examined competing factorial models and validity in relation to the Big Five personality traits (Extraversion, Agreeableness, Conscientiousness, Neuroticism, Openness). Study 2 (N = 358) replicated the analysis of factor structure and assessed validity in comparison with five time perspectives (Past Negative, Present Fatalistic, Future, Past Positive, Present Hedonistic). Participants across both studies completed standardized self-report measures capturing the variables. Results: Comparison of confirmatory factor analysis (CFA) and exploratory structural equation modelling (ESEM) factor solutions indicated that an ESEM bifactor model provided the strongest data-model fit. This included a general chronic time pressure component alongside specific subfactors of Feeling Harried and Cognitive Awareness of Time Shortage. All scale items reflected the general factor; however, some items loaded weakly on the intended specific factor. The CTPI is thus a robust indicator of chronic time pressure but needs refinement as a measure of the specific factors. Convergent/discriminant validity analyses inferred that the CTPI captured chronic time pressure as a related, but distinct, construct to perceived stress, and evidenced a relationship with theoretically associated constructs (Big Five personality traits and time perspective). Overall, the CTPI is a sound measure of chronic time pressure and has the potential to further cohesive research efforts on the contribution of this construct to various life domains.

This research delves into the intricate interplay between perceived organizational support, proactive personality, and voice behavior. Furthermore, it establishes the pivotal role of work engagement as a mediating factor within the articulated research model. The study engaged 287 healthcare professionals within correctional institutions and detention centers in Indonesia, employing a dual-phase questionnaire distribution to capture the dynamic aspects of the participants' experiences. Utilizing the statistical technique of Partial Least Square-Structural Equation Modeling with the SmartPLS 4 program as an analysis tool, the collected data underwent comprehensive analysis. The outcomes reveal that proactive personality significantly influences voice behavior both directly and indirectly through its impact on work engagement. Conversely, perceived organizational support directly influences work engagement but does not exhibit a direct impact on voice behavior. These findings underscore the significance of proactive personality in fostering a conducive environment for constructive organizational change from a grassroots perspective. The study suggests that organizations prioritize the cultivation of proactive personality traits to stimulate voice behavior, thereby facilitating ongoing improvements and sustainable organizational progress.

The previous studies have found an association between Big Five personality traits and postpartum depression in women. The present study aimed to find out an association between Big Five personality traits and postpartum depression in a sample of Pakistani fathers. A total of 400 Pakistani fathers who had birth of a child in the past 1 month to 1 year period and had been living with their married partners were recruited purposively by using Google Form based survey from the major cities of Pakistan. The Urdu translated versions of Big Five Personality Inventory (BFI) and Edinburgh Postnatal Depression Scale (EPDS) were used as the main outcome measures to assess the relationship between personality traits and postpartum depression. The results found a significant negative and moderate association between Big Five personality traits and paternal postpartum depression except openness which had a weak association and neuroticism which had a positive and moderate association with PPPD (r(398) = .45). The multiple linear regression analysis found that Big Five personality traits significantly predicted paternal postpartum depression (F(5, 394) = 53.33, p = .001) except openness (B = .007, p = .98). The analysis of variance (ANOVA) found significant differences in paternal postpartum depression for age of father (F(2, 397) = 6.65, p = .001, ηp2 = .03), spouse age (F(2, 393) = 5.97, p = .003, ηp2 = .02), employment type (F(2, 395) = 9.69, p = .001, ηp2 = .04) and time spent at home (F(2, 397) = 6.23, p = .002, ηp2 = .03) while there were found no significant differences for education (F(2, 397) = 1.29, p = .27, ηp2 = .006), marital duration (F(2, 397) = 2.17, p = .11, ηp2 = .01), and birth number of recent child (F(2, 397) = 1.48, p = .22, ηp2 = .007). The study concluded that Big Five personality traits are significantly correlated with and predict paternal postpartum depression except openness which did not predict paternal postpartum depression. The occurrence of paternal postpartum depression varied significantly for age of father, age of spouse, type of employment and time spent at home.

Interest in psychedelics is increasing due to the potential for improved mental health and quality of life. However, adverse effects on mental health are still a concern. Personality traits have been suggested to both influence the psychedelic experience and mental health, and even be changed by psychedelic use. The present study describes for the first time a national sample of Swedish psychedelic users (n = 400) compared to a sex and age-matched control-group of non-users (n = 400) regarding mental health variables (depression, insomnia, problematic alcohol and drug use, and dissociation) and personality (Big Five). Data was collected in an online survey including individuals from 16 years of age who had at least one psychedelic experience. The main results reported psychedelic users as less depressed (Patient Health Questionnaire-9; PHQ-9) (d = - 0.29) and having more use of drugs (Drug Use Disorders Identification Test; DUDIT) (d = 1.27). In the Big Five personality traits, openness differed notably (d = 1.72), and the between-group effects in PHQ-9 were explained by lower neuroticism. Our findings reveal that psychedelic users report less depression and higher drug use, and this is partly due to personality traits. These results have implications on how we view psychedelic users and the use of psychedelic drugs.

Previous studies have suggested behavioral patterns, such as visual attention and eye movements, relate to individual personality traits. However, these studies mainly focused on free visual tasks, and the impact of visual field restriction remains inadequately understood. The primary objective of this study is to elucidate the patterns of conscious eye movements induced by visual field restriction and to examine how these patterns relate to individual personality traits. Building on previous research, we aim to gain new insights through two behavioral experiments, unraveling the intricate relationship between visual behaviors and individual personality traits. As a result, both Experiment 1 and Experiment 2 revealed differences in eye movements during free observation and visual field restriction. Particularly, simulation results based on the analyzed data showed clear distinctions in eye movements between free observation and visual field restriction conditions. This suggests that eye movements during free observation involve a mixture of conscious and unconscious eye movements. Furthermore, we observed significant correlations between conscious eye movements and personality traits, with more pronounced effects in the visual field restriction condition used in Experiment 2 compared to Experiment 1. These analytical findings provide a novel perspective on human cognitive processes through visual perception.

Personality questionnaires stand as crucial instruments in personnel selection but their limitations turn the interest towards alternatives like game-related assessments (GRAs). GRAs developed for goals other than fun are called serious games. Within them, gamified assessments are serious games that share similarities with traditional assessments (questionnaires, situational judgment tests, etc.) but they incorporate game elements like story, music, and game dynamics. This paper aims to contribute to the research on serious games as an alternative to traditional personality questionnaires by analyzing the characteristics of a gamified assessment called VASSIP. This gamified assessment, based on an existing measure of the Big Five personality traits, incorporates game elements such as storyfication, immersion, and non-evaluable gamified dynamics. The study performed included 98 university students (77.6% with job experience) as participants. They completed the original personality measure (BFI-2-S), the gamified evaluation of personality (VASSIP), a self-report measure of the main dimensions of job performance (task performance, contextual performance, and counterproductive work behaviors), and measures of applicant reactions to BFI-2-S and VASSIP. Results showed that the gamified assessment behaved similarly to the original personality measure in terms of reliability and participants' scores, although the scores in Conscientiousness were substantially higher in VASSIP. Focusing on self-reports of the three dimensions of job performance, regression models showed that the gamified assessment could explain all of them. Regarding applicant reactions, the gamified assessment obtained higher scores in perceptions of comfort, predictive validity, and attractiveness, although the effect size was small except for the latter. Finally, all applicant reactions except for attractiveness were related to age and personality traits. In conclusion, gamified assessments have the potential to be an alternative to traditional personality questionnaires but VASSIP needs more research before its application in actual selection processes.

Maladaptive personality traits, such as 'dark personalities' are found to result in a diverse set of negative outcomes, including paraphilic interests and associated (illegal) behaviors. It is however unclear how these are exactly related, and if related, if then only those individuals higher on dark personality traits and higher impulsivity engage in paraphilic behaviors. In the current study, 50 participants were recruited to investigate the relationship between Dark Tetrad personality traits (i.e., narcissism, psychopathy, Machiavellianism and everyday sadism), paraphilic interests (arousal and behavior) and the moderating role of impulsivity. Personality and paraphilic interests were investigated through self-report questionnaires. Impulsivity was measured both through self-reported dysfunctional impulsivity and the P3 event related potential using electroencephalography during the Go/No-Go task (i.e. response inhibition). The results showed that there was a positive association between psychopathy, sadism and paraphilic interests. Whereas everyday sadism was associated with paraphilic (self-reported) arousal, psychopathy was associated with paraphilic behavior. Although P3 amplitude was not associated with paraphilic interests, self-reported dysfunctional impulsivity was associated with paraphilic behavior specifically. However, there was no moderating role of dysfunctional impulsivity and response inhibition (P3) in the relationship between psychopathy and paraphilic behavior. Findings indicate that the relation between specific dark personalities and paraphilic interests may be more complex than initially thought. Nevertheless, risk assessment and intervention approaches for paraphilia and related behavior both may benefit from incorporating Dark Tetrad and impulsivity measurements.

BACKGROUND: There have been few longitudinal studies on Chinese bus drivers and the individual differences in the relationships between organizational justice and job satisfaction. This study examined the organizational justice and job satisfaction in bus drivers and the individual differences in this relationship. METHODS: A two-wave longitudinal study design was employed. A first survey was conducted on 513 Chinese bus drivers in October 2021 that collected socio-demographic information and asked about their perceptions of organizational fairness. A second survey was conducted six months later that asked about role overload and job satisfaction and assessed their proactive personality type. An effect model was then used to explore the moderating effects of role overload and proactive personality type on the relationships between organizational justice and job satisfaction. RESULTS: Both procedural and interactive justice predicted the bus drivers' job satisfaction. Proactive personalities and role overload were found to enhance this relationship. CONCLUSIONS: Organizations could benefit from screening at the recruitment stage for drivers with highly proactive personalities. Relevant training for drivers with low proactive personalities could partially improve employee job satisfaction. When viewed from a Chinese collectivist cultural frame, role overload could reflect trust and a sense of belonging, which could enhance job satisfaction. Finally, to improve employee job satisfaction, organizations need to ensure procedural and interactive justice.

BACKGROUND: The aim of this research was to analyze whether the personality factors included in the Big Five model differentially predict the self-regulation and affective states of university students and health. METHODS: A total of 637 students completed validated self-report questionnaires. Using an ex post facto design, we conducted linear regression and structural prediction analyses. RESULTS: The findings showed that model factors were differential predictors of both self-regulation and affective states. Self-regulation and affective states, in turn, jointly predict emotional performance while learning and even student health. These results allow us to understand, through a holistic predictive model, the differential predictive relationships of all the factors: conscientiousness and extraversion were predictors regulating positive emotionality and health; the openness to experience factor was non-regulating; nonregulating; and agreeableness and neuroticism were dysregulating, hence precursors of negative emotionality and poorer student health. CONCLUSIONS: These results are important because they allow us to infer implications for guidance and psychological health at university.

BACKGROUND: Many studies have indicated that negative emotions and personality traits are related to psoriasis, though few have provided causal evidence. METHODS: Our analysis utilized 15 genome-wide association study datasets to identify instrumental variables associated with negative emotions, personality traits and psoriasis vulgaris. Two-sample Mendelian randomization was conducted to identify the causal associations of negative emotions and personality traits with psoriasis vulgaris. To mitigate bias from multiple tests, we adjusted p-values using the Benjamini-Hochberg method. RESULTS: Our study revealed causal links between negative emotions and psoriasis vulgaris, including depressed affect, worry too long, feeling hurt, guilty feelings, mood swings, unenthusiasm, miserableness, fed-up feelings. However, there was no significant evidence of a causal relationship between feeling lonely and psoriasis vulgaris. Additionally, personality traits including neuroticism and openness to experience were found to have causal effects on psoriasis vulgaris. However, no significant evidence supported a causal relationship between agreeableness, conscientiousness, and extraversion with psoriasis vulgaris. CONCLUSION: Our findings suggest that experiencing negative emotions including depressed affect, worrying excessively, feeling hurt, guilty feelings, mood swings, lack of enthusiasm, miserableness and fed-up feelings may pose risks for psoriasis vulgaris. Additionally, neuroticism is associated with a risk of psoriasis vulgaris. Conversely, the openness trait may serve a protective role against psoriasis vulgaris.

The article presents two theoretical perspectives that provide a helpful framework in psychobiographical research, especially when psychobiographies concern religious suicide. The first is typical in contemporary psychology, a subjective analysis focused on the individual, looking at life course/lifetime in the light of personality psychology. The second one is represented by anthropological research on the concept of honour-shame and the sociological works of E. Durkheim. Contemporary psychobiography should consider sociocultural context and refer to social sciences (anthropology, sociology). This applies in particular to the psychobiographies of people representing a world of values different from the Western world, i.e. non-WEIRD people. The problem is especially true of monotheistic religions that grew up in the world of honour-shame cultural code (Middle East, Mediterranean culture). The natural human need for psychological power is then woven into a specific set of beliefs and values that may, in extreme cases, favour the decision to commit suicide. Suicide acts seen in this perspective are no longer the act of sick or socially alienated people but often the act of fully healthy, conscious, educated and socially integrated people. Such a dramatic decision may become the only way to regain a sense of dignity, strength and control.

In recent years the historical subject base in psychobiography has expanded from a traditional focus on White (Caucasian) subjects to a broader more culturally inclusive population of significant personalities throughout history. A critical component of strong multicultural psychobiography is the inclusion of anchoring theories of psychology that are rooted in socio-cultural-political context. To psychologically profile culturally diverse individuals with only traditional Western theories of psychology and psychiatry (e.g. medical models, psychodynamic, existential, cognitive-behavioral) limits the ability of the research to accurately capture the erlebnis (lived experience) of extraordinary individuals in proper cultural context. This article reviews specific psychological theories that have recently set a foundation for more nuanced and culturally contextualised psychological profiles of historic personalities who represent diverse racial/ethnic/cultural backgrounds. Among the theories covered are the Integrated African Psychology Perspective (IAPP), an Indigenous (Native American) model of psychobiography, as well as theories and models on Psychological Nigrescence (Black racial identity development), Intersectionality, Politicised Collective Identity (PCI), Queered Black Racial Identity Development (QBRID), and Adultification of Black Children, among others. Examples of applications of these culture-centered theories to psychobiography, drawn from the present authors recently completed psychobiographies, as well as from other researchers internationally, are presented.
