The literature has described how different and independent personality profiles (pathways or motives) lead to the same outcome: alcohol misuse. In addition, decision-making styles could also play a role in understanding alcohol misuse better, although the evidence is much more scarce compared to personality traits. The present paper aims to test how personality traits and decision-making styles could be integrated to better understand different pathways/profiles of alcohol misuse. Measures of alcohol misuse (AUDIT and RAPI), structural personality models (ZKA-PQ/SF), impulsivity (BIS-11 and UPPS-P), and decision-making styles (GDMS) were applied to a sample of 988 individuals from the Spanish general population (446 of them also completed the NEO-PI-R). Exploratory factor analyses support the identification of different pathways to alcohol misuse, and regression analyses suggest that decision-making styles add little variance to personality traits to account for differences in alcohol misuse, although the spontaneous style is consistently associated with alcohol misuse. The conclusions highlight the need to consider different aetiologies of alcohol misuse, especially an antisocial/disinhibited profile, and claim for the assessment of decision-making styles and, especially, personality traits to facilitate more successful treatment and prevention programs for alcohol misuse.

This study investigated prefrontal cortex activity during the viewing and evaluation of pictures depicting scenarios with varying levels of danger, with a focus on the modulatory effects of personality traits and decision-making styles. The study sample included 120 male participants (44.4 ± 12.9 years) and 87 female participants (38.9 ± 10.5 years). Functional Near-Infrared Spectroscopy (fNIRS) was used to measure prefrontal oxygenation during the period of looking at pictures and the subsequent period of judging how dangerous they looked. Psychometric assessments included the Zuckerman–Kuhlman–Aluja Personality Questionnaire (ZKA-PQ) and the Melbourne Decision-Making Questionnaire (MDMQ). The results revealed significant time-by-region (F = 2.9, p = 0.013) and danger level by region interactions (F = 2.8, p = 0.021) during the viewing period. During the evaluation period, a significant time-by-region interaction was observed (F = 8.7, p < 0.001). High sensation seekers exhibited reduced oxygenation levels in specific right prefrontal regions, reflecting a differential neural response to varying danger levels. Similarly, individuals with higher Aggressiveness and Extraversion displayed distinct oxygenation patterns during the evaluation phase, suggesting that personality traits influence prefrontal activity. However, no significant effects of decision-making styles were detected in either phase. These findings emphasise the pivotal role of the prefrontal cortex in assessing scene safety and highlight how neural responses are modulated by personality traits, rather than by decision-making styles.

This study compares the Melbourne Decision-Making Questionnaire (MDMQ) and the General Decision-Making Style questionnaire (GDMS), two of the most widely used decision-making questionnaires in the literature, in a large age- and sex-weighted general population sample of 714 men (45.7%) and 848 women (54.3%) between 18 and 90 years old. The objective was to evaluate the convergent and construct validity between several aspects of these decision-making style questionnaires. The results indicate that the two questionnaires replicate the factorial structure of four and five factors reported in the original studies, respectively, through exploratory and confirmatory procedures in our cross-cultural context. The domains of both questionnaires that represent a strong or large correlation are Vigilance with Rational (0.50), and Hypervigilance, Buck-passing, and Procrastination with Avoidant (0.45, 0.52, and 0.60). A Structural Equations Model (SEM) between both questionnaires indicates that both latent factors formed by the domains of the MDMQ and the GDMS obtain a correlation of 0.96. It is concluded that the two questionnaires measure similar aspects of the decision-making construct.

Previous relationships between Dark Triad and Humor styles are theoretically difficult to interpret since Dark Triad traits present general and specific sources of variance. In the present study, we used structural equation modelling techniques to allow us to separate the two sources and detect which source of variance of Dark Triad plays the main role in the relationship observed with Humor styles. Similarly, it was tested if relationships among measures of Self-esteem and Humor styles are replicated at structural level. Moreover, the vast majority of previous studies have been conducted with university samples, which represents a limitation. Hence, a series of bi-factor models to test the relationship between Dark Triad and Humor styles and structural models for Self-esteem and Humor styles were fitted on a community sample of 987 Spanish people. Results suggest that the common variance of the Dark Triad traits was mainly responsible for the reported relationships with Humor styles. It is noteworthy that relations reported for Aggressive and Self-defeating humor styles were higher than those observed in previous studies. Similarly, a higher correlation between Self-esteem and Self-defeating was observed at the structural level. Futures studies are suggested to better establish the psychological reasons behind these relationships.

This study was designed to examine the relationships among the impulsivity construct as a personality trait, the dehydroepiandrosterone sulfate (DHEA-S), and testosterone in a sample of 120 healthy middle-aged males (Mage = 44.39; SD = 12.88). The sum of the three BIS-11 scales, the SR, and the five UPPS-P scales correlated with DHEA-S 0.23 (p < 0.006) and testosterone 0.19 (p < 0.04), controlling for age. Partial correlations showed that DHEA-S was significantly related to motor impulsivity (0.24; p < 0.008), Sensitivity to Reward (0.29; p < 0.002), Lack of Premeditation (0.26; p < 0.05), and, to a lesser extent, Sensation Seeking (0.19; p < 0.04) and Positive Urgency (0.19; p < 0.04). Testosterone correlated with attention impulsivity (0.18; p < 0.04), Sensation Seeking (0.18; p < 0.04), and Positive Urgency (0.22; p < 0.01). Sensitivity to Reward, Negative Urgency, and Positive Urgency were significant predictors of DHEA-S (R2 = 0.28), and Positive Urgency for testosterone (R2 = 0.09). Non-parametric LOESS graphical analyses for local regression allowed us to visualize the non-linear relationships between the impulsivity scales with the two androgens, including non-significant trends. We discuss the implications of these results for impulsive biological personality traits, the limitations of our analyses, and the possible development of future research.

Background This study was designed to examine the prevalence and relationships between the Internet gaming disorder (IGD) behaviors, suggested by the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), and personality traits. Participants and procedure A sample community of 1,548 subjects, 707 men and 841 women, with a mean age of 40.90 and 38.89 years, respectively, was evaluated. Results The results showed that only 7 subjects (0.5%) exceeded the cut-off point of 75 points to be classed as “disordered gamers” proposed by Fuster et al. (2016) in Spain. This study demonstrates the unidimensionality of the IGD-20, so it can be used as an ordinal dimensional measure to study the relationship between IGD symptoms and other related variables such as per-sonality in community samples. A multiple linear regression analysis revealed that up to 8% of the variance of the Internet Gaming Disorder-20 scale (IGD-20), as a dimensional scale, can be explained by low activity, high aggressiveness, introver-sion, non-planning impulsivity, sensation seeking, neuroticism and impulsiveness (attention impulsivity) using the Alterna-tive Five Factor Model (AFFM) of personality and the Barratt Impulsivity Scale (BIS-11). Conclusions This study shows that the prevalence of IGD in the Spanish population is similar to that of other Western countries. The unidimensionality of the IGD-20 allows its use in correlational studies to examine the relationship between Internet gam-bling behaviors and personality variables. The implications of these personality profiles are discussed in relation to the psy-chological and clinical mechanisms involved in Internet gaming disorder.

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 aims to investigate the relationships between personality traits of impulsivity, using the UPPS-P Impulsive Behaviour Scales shortened version, and prefrontal cortex (PFC) activity during the IOWA Gambling Task (IGT) in young adult women. The study included a sample of 83 young, healthy females (19.8 ± 1.4 years), who voluntarily took part in the study. Repeated measures analysis during the IGT revealed a significant increase in HbO (all p <.001; ηp2 >.31) and a decrease in Hbr (all p <.003; ηp2 >.08) in all prefrontal quadrants. This increase in oxygenation occurs primarily during the choice period under ambiguity (r =.23; p =.039). Additionally, there was a significant linear decrease in selecting the decks associated with a high frequency of losses (p <.001), while the favorable deck with low losses showed a linear increase (F = 12.96; p <.001). Notably, discrepancies were found between UPPS-P and IGT impulsivity ratings. The Lack of Perseverance and Lack of Premeditation scales from the UPPS-P were identified as significant predictors of HbO levels, mainly in the two quadrants of the left hemisphere’s, lateral (adjusted R2 =.23; p <.001; f2 =.34) and rostral (adjusted R2 =.13; p <.002; f2 =.17). These findings suggest that young adult women predominantly adopt a punishment-avoidance strategy during IGT, exhibiting increased activation in the left hemisphere, especially during the task’s initial phase characterized by ambiguity.

Background: Road safety improvement is a governmental priority due to driver-caused accidents. Driving style variation affects safety, with emotional regulation being pivotal. However, functional near-infrared spectroscopy (fNIRS) studies show inconsistent prefrontal cortex activity during emotion processing. This study examines prefrontal cortex response to negative emotional stimuli, particularly traffic accident images, across drivers diverse in age and gender. Method: The study involved 118 healthy males (44.38 ± 12.98 years) and 84 females (38.89 ± 10.60 years). The Multidimensional Driving Style Inventory (MDSI) was used to assess driving behavior alongside fNIRS recordings. Participants viewed traffic accident and neutral images while prefrontal oxygenation was monitored. Results: Women rated traffic accidents (t-test = 2.43; p < 0.016) and neutral images (t-test = 2.19; p < 0.030) lower in valence than men. Arousal differences were significant for traffic accident images (t-test = −3.06; p < 0.002). correlational analysis found an inverse relationship between Dissociative scale scores and oxygenation (all p-values ≤ 0.013). Greater prefrontal oxygenation occurred with neutral images compared to traffic accidents. Left hemisphere differences (t-test = 3.23; p < 0.001) exceeded right hemisphere differences (t-test = 2.46; p < 0.015). Subgroup analysis showed male participants to be driving these disparities. Among adaptive drivers, significant oxygenation differences between neutral and accident images were evident in both hemispheres (left: t-test = 2.72, p < 0.009; right: t-test = 2.22, p < 0.030). Conclusions: Male drivers with maladaptive driving styles, particularly dissociative ones, exhibit reduced prefrontal oxygenation when exposed to neutral and traffic accident images. This response was absent in female drivers, with no notable age-related differences.

The present study was planned to study the relationships between age, personality (according to Zuckerman's and Gray's psychobiological models) and decision-making styles in relation to risky driving behaviors. The participants were habitual drivers, 538 (54.3%) men and 453 (45.7%) women, with a mean age around 45 years and mainly of middle socioeconomic status. The results indicate that the youngest men and women reported more Lapses, Ordinary violations, and Aggressive violations than the oldest men and women. Women reported more Lapses (d = -0.40), and men more Ordinary (d = 0.33) and Aggressive violations (d = 0.28) when driving. Linear and non-linear analysis clearly support the role of both personality traits and decision-making styles in risky driving behaviors. Aggressiveness, Sensitivity to Reward, Sensation Seeking played the main role from personality traits, and Spontaneous and Rational decision-making style also accounted for some variance regarding risky driving behaviors. This pattern was broadly replicated in both genders. The discussion section analyses congruencies with previous literature and makes recommendations on the grounds of observed results.

The cross-cultural factor invariance of the Humor Styles Questionnaire (HSQ) structure, and its relationships with the HEXACO personality model were analyzed in a large Spanish community sample. The effect of age, gender, and social position on the observed relationships was also investigated. The four-factor structure of the HSQ was largely invariant compared to the original one. Males and younger participants score higher on all four domains of the HSQ, but no relevant effect of social position is observed. The HEXACO-60 dimensions and facets predicted between 17% and 32% of the HSQ domains. Results and discussion broadly support that the HEXACO personality model can be used as an adequate personality framework for the research and understanding of humor styles.

This study focused on inspecting the relationship between impulsivity traits, salivary dehydroepiandrosterone sulfate (DHEA-S) concentrations, and moderate alcohol consumption in healthy subjects. In previous studies, impulsivity has been related to alcohol consumption and androgens. Limited research has focused on the sulfated form of DHEA-S and alcohol consumption or impulsivity. Moderate alcohol consumption can increase DHEA-S levels. Effects of alcohol, impulsivity and androgens levels may depend on age and gender. The participants were 120 healthy men (Mage = 44.39; SD = 12.88). The results showed positive correlations between DHEA-S and alcohol consumption (r = 0.22; p < .01) and an impulsivity factor (r = 0.22; p < .01) controlling for age. Regression analysis showed a significant relationship between DHEA-S (p < .001), impulsivity factor and AUDIT (p < .05). Analyzing the two extreme impulsivity groups, an association is observed between DHEA-S with AUDIT scores (R2 = 0.12; p < .05) in the high impulsivity group, but not in the low impulsivity one. It is therefore concluded that the effect of moderate alcohol consumption is cumulative and slightly associated with levels of impulsiveness and DHEA-S.

Available data indicate that the frequency of Problematic Smartphone Use (PSU) has been increasing over the years. Although there is some debate as to whether or not this behavior corresponds to true addiction, comorbidity has been found with problematic outcomes typically related to traditional addictions. Thus, there is interest in better understanding which individual variables interact with this behavior. The present study uses a large sex-balanced sample covering a wide age range to shed light on this question. The main purpose of this study is to examine the relationship between personality, assessed by Zuckerman's alternative five-factor model, and PSU. The possible mediating role of individual decision-making styles as well as the effect of sociodemographic variables such as age, sex, and social position are also investigated. The results indicated a strong association between Aggressiveness, Neuroticism, and, to a lesser extent, Sensation Seeking with PSU. The decision-making styles that were most related to the problematic use of smartphones were Avoidant and Spontaneous. Neuroticism, Sensation Seeking, and Aggression explained 24% of the variance of the PSU measure. Only Avoidant showed some incremental validity for this model. However, a mediation analysis by structural equation modeling revealed generally significant indirect effects for Avoidant and Spontaneous, explaining part of the effect of personality on the factor assessed by the PSU measure. The percentage of variance explained for latent scores ranged from 20-32%. The practical implications of the study and future research directions are discussed.

This study explores the relationship between decision-making style, as measured by the Melbourne Decision Making Questionnaire, and personality based on alternative five-factor model along with effect of age, sex and social position on such styles. A large sample of community and undergraduate students (n = 1,562; Mage = 40.03, SD = 18.43) was analyzed. The results showed that Neuroticism and Extraversion were significantly related to the non-vigilant styles Hypervigilance, Buck-passing and Procrastination. Women scored significantly lower in Vigilance and higher in Hypervigilance, Buck-passing and Procrastinations than men. Age was significantly related to decision-making style in a U-shaped fashion. The Social Position Index was significantly related to all decision-making styles. The most predictive personality domains regarding decision-making scales were Aggressiveness (negatively) and Activity for Vigilance, and Neuroticism for Hypervigilance, Buck-passing and Procrastination. Age, sex and social position had a small/medium overall effect on the four dimensions of Melbourne Decision Making Questionnaire (p < 0.001) with a η2 of 0.038, 0.068, 0.050, and 0.031 for Vigilance, Hypervigilance, Buck-passing and Procrastination, respectively. Based on scores on a single factor dimension of the MDMQ, the profile of participants with higher scores was characterized by lower age, more likely to be females, lower social position, higher levels of Aggressiveness, less Activity, less Extraversion, and higher Neuroticism.

The Prefrontal cortex (PFC) has been highly related to executive functions such as working memory (WM). This study assesses the activity of the PFC in performing the Sternberg WM task (ST) with three levels of difficulty (easy, medium and hard) using the near-infrared spectroscopy (fNIRS) technique. Participants were 43 young and healthy right-handed women. Nine WM task blocks were pseudo randomly presented, three for each difficulty task. The results showed that the participant's performance was better in the easy trials than in the medium and hard trials. Performance in the medium trials was also better than in the hard ones. Bonferroni-corrected paired post-hoc t-tests indicated higher oxygenation in medium and hard tasks than in the easy ones for times between 13 and 42 s in the left lateral PFC and in both, medial and lateral, right PFC. Significant differences in Oxygenated hemoglobin (HbO), Total hemoglobin (HbT) and oxygenation (Oxy) changes depending on the Sternberg WM task were found. Unlike previous studies with fNIRS and WM, the current study uses a highly controlled WM task that differentiates between encoding, retention and retrieval phases, comparing different levels of task load.

The current research was designed to assess possible differences in the emotional content of pleasant and unpleasant face emoji using acoustically evoked eyeblink startle reflex response. Stimuli were selected from Emojipedia Webpage. First, we assessed these stimuli with a previous independent sample of 190 undergraduate students (46 males and 144 females) mean age of 21.43 years (SD 3.89). A principal axis method was performed using the 30 selected emoji faces, extracting two factors (15 pleasant and 15 unpleasant emoji). Second, we measured the acoustic startle reflex modulation in 53 young adult women [mean age 22.13 years (SD 4.3)] during the viewing of each of the 30 emoji emotional faces in the context of the theory of motivation and emotion proposed by Lang (1995), but considering only the valence dimension. We expected to find higher acoustically evoked startle responses when viewing unpleasant emoji and lower responses for pleasant ones, similarly to the results obtained in the studies using human faces as emotional stimulus. An ANOVA was conducted to compare acoustic startle responses associated with pleasant and unpleasant emoji. Results yielded main effects for picture valence (λ = 0.80, F(1, 50) = 12.80, p = .001, η2 = 0.20). Post-hoc t test analysis indicated significant differences in the startle response between unpleasant (50.95 ± 1.75) and pleasant (49.14 ± 2.49) emoji (t (52) = 3.59, p = .001), with a Cohen's d = 0.495. Viewing affective facial emoji expressions modulates the acoustic startle reflex response according to their emotional content.

This study re-explores the relationship between metabolic syndrome (MetS), according to IDF and NCEP criteria, and personality and psychopathological variables. We studied trait anger, type A behavior, type D personality, alexithymia, Zuckerman’s personality dimensions, anxiety, somatization, depression, and hostility. The sample was 410 males (Mage = 52.54, SD = 10.43). A cross-sectional design was used with self-report data from questionnaires and biological measures. Participants completed the type D scale (DS14), the Jenkins Activity Survey (JAS), the Toronto Alexithymia Scale (TAS-20), the State-Trait Anger Expression Inventory-2 (STAXI-2), the Brief Symptom Inventory (BSI) and the shortened cross-cultural Zuckerman-Kuhlman Personality Questionnaire (ZKPQ-50-CC). The results show that subjects with IDF/NCEP criteria have significantly high scores in anxiety/negative affect, aggression-hostility, trait anger, alexithymia, negative affect, somatization, depression, and anxiety, but not in type A. No differences were found between both MetS criteria. High scores in somatization, difficulty in describing feelings, impulsive sensation seeking, and low scores in activity predict a small, but significant, part of the variance of systolic pressure, HDC cholesterol, triglycerides, glucose, and waist circumference. This study provides certain evidence for an association between MetS and psychological variables, including psychopathological symptoms, according to IDF and NCEP criteria.
