Across two studies (cross-sectional and 4-wave longitudinal), "healthy personality"—higher extraversion, agreeableness, conscientiousness, openness, plus lower neuroticism—consistently predicted higher well-being (mental health, life satisfaction, worthwhileness), driven mainly by overall trait elevation rather than resemblance to a specific personality "profile." Healthy personality did predict higher levels, but not stability or change, in well-being or psychological richness (novelty, challenge, perspective shifts) over time.

This study compared 125 older adults (71–101 years) from Sardinia's Blue Zone versus a nearby non-Blue Zone. Openness, conscientiousness, and agreeableness correlated with better psychological well-being; neuroticism correlated with lower Health-Related Quality of Life (HRQoL). Blue Zone residents showed higher openness, better coping and emotional competence, and more leisure engagement than non-Blue Zone peers, suggesting adaptive personality traits and active lifestyles jointly support successful aging in this exceptional-longevity population.

Analyzing four large panels (N=63,502), this study found reciprocal, small effects between loneliness and Big Five traits over 4-year intervals. Higher-than-typical extraversion, conscientiousness, and emotional stability each predicted lower subsequent loneliness (βs ≈ -0.02 to -0.04). Conversely, elevated loneliness predicted later declines in extraversion, conscientiousness, and emotional stability (βs ≈ -0.02 to -0.03). Agreeableness and openness showed weaker, less consistent associations, suggesting a genuinely bidirectional but modest relationship between loneliness and specific personality traits.

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.

This handbook explores the multidimensional science of Subjective Well-Being (SWB), which encompasses positive emotions, life satisfaction, and optimism. By synthesizing philosophical history with empirical research, the text examines how biological, cultural, and policy-driven factors influence happiness. Key theoretical frameworks, such as set-point models, suggest that individuals have a baseline level of happiness to which they eventually return after life events. Ultimately, the work aims to explain the variance in human flourishing by analyzing the predictors and outcomes that distinguish satisfied lives from unsatisfied ones.

This research emphasizes that family ties (specifically marital, intergenerational, and sibling relationships) serve as primary pillars of psychological well-being throughout adulthood. The study highlights that the quality of these connections often matters more than their mere existence, noting that diverse family structures significantly influence how support is exchanged. Interestingly, the researchers suggest that future study should focus on the 'unexpected benefits' of relationship strain and how intersecting social statuses shape family dynamics. Ultimately, understanding these complex interactions is essential for promoting long-term resilience and emotional health within various family units.

This chapter conceptualizes Subjective Well-Being (SWB) as a multidimensional construct, addressing modern definitional controversies and comprehensive models. It examines how personality processes underlie SWB and explores whether baseline happiness levels can actually change over time. Beyond individual experience, the review highlights the practical application of SWB data in public policy, using happiness metrics to inform societal decisions and promote broad human flourishing through empirical research.

The development of the Heartland Forgiveness Scale (HFS) highlights forgiveness as a multidimensional trait involving the self, others, and uncontrollable situations. Research shows that high levels of dispositional forgiveness correlate with cognitive flexibility and positive affect, while serving as a powerful buffer against rumination and hostility. Notably, forgiveness of situations (accepting circumstances beyond one's control) uniquely predicts improvements in life satisfaction and reductions in anxiety and depression. Within relationships, forgiveness is as critical as trust, accounting for unique variance in long-term satisfaction and reflecting a measurable shift from past negativity to present-tense healing.

Research across four studies identifies gratitude as a distinct disposition strongly linked to higher well-being, prosociality, and spirituality. Notably, the grateful disposition is negatively associated with envy and materialism. These relationships remain significant even when controlling for Big Five traits like Extraversion, Neuroticism, and Agreeableness, proving that gratitude offers unique psychological insights beyond general personality. To facilitate future research, the authors developed the Gratitude Questionnaire (GQ-6), a highly reliable unidimensional scale.

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 longitudinal study identifies three distinct pathways to positive mental health in women, categorized by their levels of Environmental Mastery (EM) and Personal Growth (PG). Achievers excel in both, while Conservers prioritize stability and mastery, and Seekers focus on continuous self-development. Each group exhibits unique strengths in competence, wisdom, and generativity, with their late-life mental health outcomes being significantly shaped by their personality at age 21 and identity formation by age 43.

This longitudinal study analyzed the early-life autobiographies of 180 nuns to determine if emotional content predicts longevity. Researchers discovered a powerful inverse relationship between positive emotions expressed at age 22 and mortality risk between ages 75 and 95. Those in the highest quartile of positive emotion lived significantly longer, showing a 2.5-fold lower risk of death compared to the lowest quartile. These findings suggest that a positive emotional baseline in early adulthood serves as a long-term predictor of survival decades later.

The emergence of positive psychology marks a fundamental shift from a 'disease model' (which focuses exclusively on repairing pathology) toward a science of human flourishing. This framework emphasizes the study of positive subjective experiences, individual traits like courage and wisdom, and institutions that improve quality of life. By focusing on strengths such as optimism, hope, and self-regulation, researchers aim to understand what makes life worth living rather than merely how to treat mental illness. This proactive approach suggests that building internal resilience and fostering talent are essential for preventing future pathologies and allowing individuals and communities to thrive.

This research confirms a robust relationship between Extraversion and pleasant affect, finding moderate to strong correlations across various assessment scales. However, the method of measurement significantly impacts the results. Global, retrospective reports (where individuals recall their moods over time) yield higher correlations than 'on-line' assessments, such as daily diaries or moment-to-moment reports. These real-time methods produce lower, more consistent correlations, suggesting that the Extraversion-happiness link is partly influenced by how people cognitively summarize their emotional experiences.

This meta-analysis of 137 personality constructs identifies how specific traits drive subjective well-being. While personality strongly predicts life satisfaction and happiness, it is less predictive of negative affect. Within the Big Five, Neuroticism stands as the primary predictor of overall satisfaction, while Extraversion and Agreeableness contribute equally to positive affect. These findings suggest that emotional stability and social connection are the foundational pillars of long-term human happiness.

This review examines the evolution and structure of extraversion, tracing its development from early typological views to modern trait-based models. It integrates foundational theories with contemporary perspectives linking extraversion to affect and personality frameworks. The authors propose a cohesive model outlining its core components and underlying structure, offering a clearer understanding of how extraversion emerges and functions within broader personality systems.
