This study examined how narcissistic traits influence women's cognitive processing of verbal violence. Using a lexical decision task, an emotional Stroop task, and event-related potentials, we analyzed neural responses to violent versus neutral words in 70 women. Behaviorally, while narcissism showed no significant impact on performance in the Lexical Decision Task, a specific interference effect emerged in the emotional Stroop task, where higher narcissistic vulnerability predicted reduced accuracy for violent words relative to neutral ones. Notably, ERP results revealed a consistent pattern across both tasks: higher PNI total scores significantly predicted reduced amplitudes of early components, specifically the N170 and P2. Furthermore, in the emotional Stroop task, the vulnerability dimension emerged as a significant predictor of reduced EPN and P2 amplitudes. These findings suggest that when exposed to verbal violence, narcissistic women exhibit attenuated early evaluation and attentional allocation. This reflects a preemptive cognitive avoidance strategy used to protect the self-concept, driven primarily by a general narcissistic defensive pattern that manifests most acutely in vulnerable traits under high-interference conditions.

Background: Depression, anxiety, and stress are common disorders among school adolescents, affecting their emotional well-being and academic performance. In Peru, there is a lack of brief, validated instruments to detect these symptoms in educational settings, which limits timely intervention.

Objective: To adapt and validate the Spanish version of the 8-item Depression, Anxiety, and Stress Scale (DASS-8) in Peruvian school adolescents.

Methods: A total of 801 Peruvian adolescents between 11 and 18 years of age (M = 14.04; SD = 1.54) participated. An instrumental design was used, including translation and cultural adaptation of the DASS-8. Confirmatory factor analysis (CFA), reliability estimates (α and ω), and factorial invariance testing by sex, stage of adolescence, type of institution, and place of residence were conducted.

Results: The model showed excellent fit (χ² = chi-square)(17) = 48.000, Comparative Fit Index (CFI) = 0.99, Tucker-Lewis Index (TLI) = 0.98, Root Mean Square Error of Approximation (RMSEA) = 0.05, and Standardized Root Mean Square Residual (SRMR) = 0.01. The subscales demonstrated high reliability: Depression (α = 0.90; ω = 0.90), Anxiety (α = 0.90; ω = 0.90), and Stress (α = 0.87; ω = 0.87), with an overall α of 0.95. Strict invariance was supported by gender and type of institution, and scalar invariance was supported across stages of adolescence and place of residence.

Conclusions: The Spanish DASS-8 is a valid, reliable, and useful tool for screening emotional symptoms in Peruvian school adolescents. To the best of our knowledge, this is the first study to evaluate the psychometric properties of the DASS-8 in Latin American school adolescents.

Traffic violations represent a significant public health concern, with professional drivers substantially impacting road safety. This pilot study compared self-report questionnaires (general personality versus domain-specific), performance-based tests, and driving simulator measures to determine which assessment method best predicts traffic offences among professional truck drivers. Participants (N = 27) completed the Impulsiveness-Venturesomeness-Empathy Questionnaire (IVE), the Road Traffic Behaviours Questionnaire (KZD), and the Vienna Risk-Taking Test Traffic (WRBTV) and performed standardised driving scenarios in a truck simulator. Performance was assessed using speed variations in five validated decision-making situations. Drivers were classified into two groups based on relatively higher and relatively lower numbers of self-reported traffic offences. The KZD demonstrated the strongest group differentiation (p = 0.034, d = 0.76). Simulator performance was significantly different between the groups (p = 0.033, d = -0.68), with offence-reporting drivers showing smaller speed reductions. The WRBTV and the IVE empathy subscale approached significance (p = 0.056 and p = 0.059, respectively). Higher empathy characterised offence-free drivers, suggesting social-emotional factors may contribute to traffic safety. General impulsiveness and venturesomeness showed no group differences. The results indicate that domain-specific questionnaires and behavioural assessments offer superior predictive validity compared to general personality measures for identifying potentially unsafe drivers. ROC analysis revealed moderate predictive validity across significant measures (AUC: 0.64-0.70), with differential patterns of sensitivity and specificity among predictors. The findings suggest implementing tiered screening approaches using domain-specific questionnaires as initial cost-effective tools, followed by simulator assessment for at-risk drivers, enabling transport companies and regulatory bodies to identify high-risk drivers proactively.

As the older adult population rapidly increases, society is entering an aged era, and attention to measures that promote healthy aging is growing. Golf, a widely practiced leisure sport, offers physical and psychological benefits for older adults. This study examined differences in successful aging, loneliness, and depressive mood according to marital status among older adults engaged in golf. A survey was conducted with 189 older adults. Data were analyzed using cross-tabulation, validity and reliability testing, multivariate analysis of variance, and post hoc tests. Statistically significant differences emerged across marital status groups. No significant differences were found in psychological aging. In physical and social aging, the married group showed more favorable outcomes than the divorced group, and in social aging, the bereaved group also scored higher than the divorced group. Emotional loneliness was greater among divorced and bereaved participants than among married ones, whereas social loneliness and depressive mood were highest in the divorced group. In sum, marital status was significantly associated with successful aging, loneliness, and depressive mood in older adults who play golf. Although golf participation was associated with more favorable psychological outcomes, divorced individuals remain particularly vulnerable in several domains, possibly owing to persistent social stigma.

Playing sports remains one of the most common avenues for youth engagement in physical activity. Yet mental health challenges, such as performance anxiety, depressive symptoms, reduced motivation, and burnout, place many young athletes at risk. As key mediators of sport participation, coaches' roles are often underscored in recognizing shifts in athlete motivation, behavior, or well-being. Gaining better insight into athlete mental health status may enable coaches to provide timely support and strengthen athlete and team well-being. In this study protocol, we employ a mixed-methods design, evaluating the effectiveness of an AI-augmented mobile application (i.e., ThriveNudge) in promoting the mental health of youth athletes. ThriveNudge helps coaches monitor athlete mental health, flag mood disruptions, and practice supportive communication via simulated chats. A target sample of four interscholastic teams (with athletes aged 14-18 years) and their head coaches will be recruited. Teams will be cluster-randomized to either the intervention condition (n = 2), receiving pre-season training to implement ThriveNudge, or to a waitlist control condition (n = 2). Primary outcomes, including athlete burnout, motivation, coach-athlete relationships, and sport enjoyment, will be measured using psychometric scales administered online. Semi-structured interviews will be conducted with coaches and athletes in the experimental group to collect qualitative data on user interface and user experience. We hypothesize that teams using ThriveNudge will report lower athlete anxiety and burnout, higher intrinsic motivation and enjoyment, and stronger coach-athlete relationships than athletes in control teams. We aim to provide a scalable and accessible digital platform that safeguards youth mental health.

Recent stressors may increase the risk of alcohol misuse. However, the number and duration of recent stress, whether social support (SS) moderates these effects, and whether this differs for men and women, are unclear. This cross-sectional study examined the effects of these factors on alcohol use severity, amount, and frequency in 462 community adult women and men. Linear regression (controlling for sex, age, and education) indicated that more stressful life events and longer stress duration were associated with a greater probability of any alcohol use and greater alcohol use severity as measured by the Alcohol Use Disorder Identification Test (AUDIT). More stressful events were associated with a greater amount of alcohol consumption. Longer stress duration also interacted with sex and SS to predict AUDIT scores, such that high SS, only for men, predicted a higher AUDIT score, but higher stress duration predicted AUDIT scores for women, regardless of SS score. More stress events with high social support predicted a greater alcohol use amount, only in men. Current findings demonstrate that significant impacts of the number and duration of recent stressors increase the risk of alcohol intake and severity. Furthermore, SS uniquely promotes drinking in men, suggesting male-specific increased alcohol risk. Future work would benefit from further disentangling whether these effects stem from certain types of SS (i.e., emotional, financial, practical) or if these effects were due to the nature of the social interactions (i.e., drinking buddies). Moreover, future work should continue to explore the multifaceted nature of stress as well as consider how sex and SS impact alcohol use.

Research on men's mental health points out gender differences in help-seeking and access to care. Traditional masculine norms (i.e., emotional repression, self-reliance, "being strong") and gender bias might conceal distress, delay treatment, and help to explain higher burdens of addiction, violence, and suicide alongside lower recorded affective/anxiety diagnoses. An exploratory narrative review was conducted. PubMed, Scopus, and Web of Science were searched for 2015-2025 studies using MeSH and terms on men's mental health, masculinities, and stigma. Eleven studies identified attitudinal barriers (i.e., self-stigma, shame, symptom minimization, mistrust, etc.) and structural barriers (i.e., limited tailored services, navigation difficulties, costs, bureaucracy, etc.) that delay identification of psychological distress symptoms, weaken therapeutic alliance, and increase dropout, especially when therapy is perceived as impersonal or ineffective. Intersectional factors (i.e., class, age, ethnicity) further contribute to access and they need to be included in the field of men's mental health. Gender-sensitive approaches and alternative masculinity role models have the potential to enhance engagement and legitimize emotional experience. To sum up, hegemonic masculinity-related gender norms, acquired through gender-differentiated socialization, are associated with adverse mental health outcomes among men. A lack of gender-sensitive awareness campaigns to reduce stigma around men's mental health may hinder prevention, delaying early identification and timely intervention. Therefore, men's mental health care should integrate gender and intersectionality transversally to improve prevention, access, diagnosis, treatment, adherence, and outcomes, supported by professional training and tailored therapeutic tools in clinical routine practice. These findings underscore the need to promote healthier, more egalitarian masculinities and to deconstruct stigmas associated with help-seeking and mental health service.

Background: Podcasts have emerged as a prominent audio medium in the everyday lives of young adults. Despite their growing popularity, the relationship between podcast listening and subjective well-being, along with the psychological mechanisms underlying this association, remains underexplored. This study investigates the relationship between podcast listening and subjective well-being among Chinese young adults and examines the serial mediating effects of perceived social presence and perceived social support. In doing so, it seeks to clarify how immediate media-related experiences are translated into more stable psychological resources that promote mental health.

Methods: A sequential explanatory mixed-methods approach was employed. The quantitative phase involved a questionnaire-based survey of 357 participants, measuring podcast listening behavior, perceived social presence, perceived social support, and subjective well-being. Serial mediation analysis was conducted to test the hypothesized indirect pathways. The qualitative phase comprised semi-structured interviews with 20 participants, and thematic analysis was used to complement and contextualize the quantitative results by exploring young listeners' subjective psychological experiences during podcast engagement.

Results: Quantitative findings revealed a significant positive association between podcast listening and subjective well-being among young adults. Both perceived social presence and perceived social support were found to mediate this relationship, constituting a statistically significant serial mediation pathway. Consistent with these results, the qualitative analysis indicated that auditory immersion in podcast listening is associated with a stronger sense of perceived social presence, characterized by feelings of companionship and parasocial interaction. This heightened sense may be internalized as perceived social support at both informational and emotional levels, and is linked to higher subjective well-being.

Conclusions: The findings demonstrate that podcasts are not merely channels for information dissemination but function as audio media with meaningful psychosocial value. By identifying the serial mediating roles of perceived social presence and perceived social support, this study extends existing theoretical frameworks to the context of audio media and offers novel empirical evidence regarding the links between digital media experiences and subjective well-being among young adults.

Despite the introduction of inclusive and gender-affirming approaches in healthcare, transgender and non-binary people continue to show poorer physical, psychological, and social outcomes, shaped by social determinants within historically pathologizing and stigmatizing contexts. This study used qualitative participatory action research with photovoice among seven transgender individuals residing in Murcia, Spain; data were generated through semi-structured interviews and focus group dialogue, applying the SHOWED technique to the visual and discursive narratives of the participants, and analyzed with Atlas.ti v8. Educational, employment, and healthcare contexts significantly condition well-being. Well-being was determined by the circumstances and support in which gender identity is constructed, within sociocultural environments marked by gender stereotypes, exclusion from social spaces, and fears regarding the irreversibility of certain transition steps. Reported lifetime negative events, social barriers, exclusion, and persistent questioning of identity were associated with increased anxiety, depressive symptoms, and insomnia. At the same time, the relevance of resilience and support networks also emerged during the sessions. Replicating photovoice in diverse settings may help identify social and territorial inequities and inform improvements in clinical practice, healthcare education, public policies, and legislation for transgender and gender-nonconforming people.

Problem behaviors among rural adolescents remain a significant public health concern, yet the temporal roles of key psychosocial resources are not well understood. Grounded in Conservation of Resources theory and Problem Behavior Theory, this study examined the longitudinal associations between psychological capital, perceived social support, and problem behaviors among rural Chinese adolescents. A three-wave, one-year longitudinal design was conducted with 770 adolescents (49.86% male, Mage = 16.36, SD = 1.57). Random-intercept cross-lagged panel models were applied to disentangle stable between-person differences from within-person processes. At the between-person level, adolescents with higher overall psychological capital and perceived social support reported lower levels of problem behavior. At the within-person level, psychological capital showed a time-specific protective effect, with short-term increases predicting subsequent reductions in problem behavior, whereas problem behavior did not predict later psychological capital. In contrast, perceived social support demonstrated reciprocal associations with problem behavior: higher support predicted later decreases in problem behavior, while elevated problem behavior predicted subsequent declines in perceived support. These findings indicate that psychological capital and perceived social support operate through distinct temporal mechanisms and highlight the importance of early internal resource development and sustained relational support in rural adolescent populations.
