Which childhood behaviors reflect the genes tied to adult personality, before adult personality even fully forms? Using polygenic scores in over 5,500 children tracked from ages 9–13, this study found genetic propensity to neuroticism was the strongest and broadest signal (showing up as anxiety, depressed mood, sleep problems, more screen time, and even lower parental education and more family conflict). Genetic openness linked to better verbal reasoning and daydreaming (and interestingly, to later self-identifying as gay or bisexual). Genetic conscientiousness predicted being organized and persistent, agreeableness predicted fewer aggressive or rule-breaking behaviors, and extraversion predicted sociability and lower shyness. Notably, some links (like prosocial behavior and sensation-seeking) only emerged at the older age band, suggesting certain genetic "personality signatures" don't show up behaviorally until a bit later in development, indicating that the traits are latent in the genome well before they're visible in behavior.

In a study of 1,216 Chinese families with preschoolers, parental neuroticism was positively linked to children's emotional and behavioral problems, with parental emotional distress (anxiety, depression, somatization) partially mediating this relationship. Network analysis identified fidgeting/squirming, stealing, unhappiness/tearfulness, and excessive fearfulness as the most central symptoms, pointing to emotional symptoms as key intervention targets.

This study tracked 334 psychiatric inpatients across treatment, examining how Big Five traits changed alongside depression severity. Neuroticism declined significantly while Conscientiousness and Extraversion increased; these trait changes correlated strongly with depression reduction. At the symptom level, higher Neuroticism predicted slower improvement across sadness, guilt, insomnia, and work difficulty, while higher Extraversion and Agreeableness predicted faster gains in specific symptoms like pessimism and self-blame; Conscientiousness showed no item-level effects.

In 116 Indonesian psychology undergraduates, neuroticism was significantly positively associated with academic stress (r = 0.207), while extraversion (r = -0.331), agreeableness (r = -0.346), conscientiousness (r = -0.199), and openness (r = -0.366) showed significant negative associations. Openness had the strongest protective effect. Findings suggest sociability, empathy, discipline, and cognitive flexibility buffer academic stress, while emotional instability heightens vulnerability, extending Western personality-stress research to a collectivist educational context.

This narrative review of 31 studies finds that chronic stress is consistently associated with higher neuroticism and lower levels of the remaining four Big Five traits. The neuroticism link is the strongest and most well-replicated; evidence for reduced conscientiousness is moderate; associations with extraversion, agreeableness, and openness are meaningful but largely cross-sectional. The relationship is likely bidirectional, and social support, coping strategies, and socioeconomic status all moderate these effects.

Zavhorodnia and Shepelova (2026) studied 147 Ukrainian university students (mean age 24, 78% women) during wartime martial law. Emotional stability was the strongest protective factor for subjective well-being, followed by openness, extraversion, and conscientiousness. Agreeableness unexpectedly predicted well-being decline, likely reflecting emotional exhaustion from caregiving demands in a predominantly female sample. Openness mediated effects of extraversion and novelty tolerance, and emotional stability moderated openness's protective role.

Oberwemmer et al. (2026) tested whether spousal bereavement produces posttraumatic growth (PTG) as Big Five trait change in 256 Dutch adults tracked across seven years with matched controls. No growth-consistent changes emerged. Instead, bereaved individuals showed a temporary neuroticism spike surrounding the loss (more pronounced in men) followed by partial recovery, plus persistently lower conscientiousness post-loss. The authors suggest perceived PTG may reflect misattributing neuroticism's decline from its peak as genuine growth.

This cross-sectional study of 291 Chinese dental students examined how Big Five traits relate to empathy, with resilience as a mediator. Extraversion, agreeableness, conscientiousness, and openness positively predicted empathic concern and perspective-taking, while neuroticism was associated with personal distress. Resilience fully mediated links between empathy and agreeableness, conscientiousness, and openness, and partially mediated its relationships with extraversion and neuroticism, suggesting resilience-building as a lever for empathy training.

This study highlights that core personality traits are powerful predictors of baseline fitness and the specific exercise intensities individuals enjoy. Notably, participants scoring high in Neuroticism experienced the most significant stress-reduction benefits from aerobic training, suggesting a targeted emotional utility for exercise. Across the spectrum, Openness, Conscientiousness, and Extraversion further dictate these behavioral patterns, providing a scientific basis for how stable traits influence physical health. By understanding these links, interventions can be better tailored to leverage an individual's personality for improved well-being and long-term fitness adherence.

This chapter explores how the Five Factor Model (FFM) relates to personality disorders, arguing that it reflects general personality structure rather than only normal traits. It reviews evidence showing that the FFM captures both adaptive and maladaptive functioning, explains similarities and differences among disorder measures, and aligns with DSM-5 trait dimensions. The authors also highlight research on maladaptive trait variants and efforts to develop corresponding assessment scales.

This longitudinal study examined how neuroticism and related vulnerability traits predict the onset of mood, anxiety, and substance use disorders. Results suggest a general neuroticism factor contributes to risk across disorders, but is most strongly linked to mood and anxiety conditions, particularly when they co-occur. The findings also indicate some disorder-specific vulnerability effects, highlighting both shared and distinct pathways from personality to psychopathology over time.

This study of 3,827 students across 19 countries reveals that high Neuroticism correlates with negative attitudes toward action and positive attitudes toward inaction. Anxiety primarily drives this bias against taking action, while collectivist beliefs further strengthen the negative link between emotional instability and proactive attitudes. These findings suggest that addressing cognitive biases toward passivity, particularly in anxious or collectivist contexts, is essential for mitigating the negative lifestyle consequences associated with Neuroticism.

This study explores how human nature and individual differences shape our responses to stress. Meta-analyses reveal that traits like Extraversion, Conscientiousness, and Openness drive 'engagement coping,' where individuals actively face challenges. Conversely, Neuroticism is linked to 'disengagement coping,' such as avoidance. These relationships are further influenced by factors like age and stressor severity, highlighting how personality and coping mechanisms interact to determine overall mental and physical health.

This study investigated how the Big Five traits and problem appraisals influence how men cope with daily stressors. Researchers found that low perceived control shifts coping from direct action toward distraction and acceptance, while stressor severity increases reliance on religion and catharsis. Importantly, traits like Neuroticism and Conscientiousness not only predict specific coping strategies but also moderate how individuals react to the severity and uncontrollability of a stressful event.

This review advocates for a dimensional approach to personality pathology over traditional categorical models, citing superior clinical and empirical validity. By utilizing taxometric and genetic analyses, the researchers identified four core domains central to personality disorders: Emotional Dysregulation, Extraversion, Antagonism, and Compulsivity. Integrating these dimensions into diagnostic systems would allow for more precise treatment, though widespread acceptance requires addressing significant practical and conceptual transition hurdles.

This study provides evidence for the 'broaden-and-build' theory, which suggests that positive emotions expand a person's cognitive and behavioral repertoire. Researchers found a reciprocal relationship where initial positive affect led to improved broad-minded coping strategies, which in turn increased future positive affect. This 'upward spiral' effect was unique to positive emotions, as negative affect did not show the same predictive power over coping mechanisms. The results suggest that fostering positive emotional states can serially enhance well-being and resilience over time.

This study bridges the gap between normal personality traits and personality disorders by examining 'socially undesirable' language. By mapping maladaptive terms onto the Big Five poles, researchers found that personality disorders are essentially extreme, socially problematic versions of standard traits. This lexical approach reinforces the Five-Factor Model’s ability to categorize dysfunctional behavior, suggesting that maladaptive personality is a matter of degree rather than a separate category.

Psychological defense is the process of regulating painful emotions like anxiety and loss of self-esteem, often through unconscious mental processes. While early theories focused on internal conflicts regarding sex and aggression, more primitive mechanisms like denial protect against external reality. Despite a period where 'cold cognition' dominated social psychology, modern perspectives view defenses on a developmental continuum, ranging from simple, early-emerging tactics to more complex, mature forms of self-regulation.

The study of how individuals manage stress has evolved through three distinct theoretical generations. Early psychoanalytic models initially merged personality and coping as one, while the subsequent transactional approach shifted focus toward situational factors and cognitive appraisals. The current 'third generation' provides a more nuanced framework that maintains clear distinctions between stable personality traits, situational coping strategies, and final adaptational outcomes. By refining these operational boundaries, researchers can better understand how specific personality profiles influence the choice of coping mechanisms and, ultimately, long-term psychological resilience.

This study confirms the Five-Factor Model (FFM) effectively distinguishes individuals with Axis I disorders from those without. Across 468 young adults, personality dimensions provided unique diagnostic insights, even when accounting for general psychopathological symptoms. These findings highlight the FFM's utility in clinical assessments, demonstrating that specific trait profiles can accurately signal diverse mental health conditions beyond broad measures of current distress.
