The evolution of performance management (PM) has shifted from a focus on rating accuracy to a focus on driving actual results. While early strategies emphasized cognitive processes to ensure 'true' performance ratings, traditional structured systems—incorporating cascading goals and competency mo...

This chapter offers a comprehensive introduction to the theoretical frameworks and empirical evidence linking personality to parenting. It begins by establishing the core concepts within personality psychology and parenting research, then transitions into a detailed review of how specific traits ...

This meta-analysis of 33,033 individuals challenges the assumption that self-reports are inherently skewed by self-enhancement. Results show that self-ratings align closely with those of well-acquainted informants (average δ=−.038), suggesting people generally view themselves realistically. Discr...

This study utilizes massive data sets of over 1.5 million participants to address the long-standing debate over whether humans can be categorized into distinct 'personality types.' While the Five Factor Model is the standard for describing individual traits, previous attempts to find consistent t...

Research involving over 44,000 participants confirms that personality traits are reliably communicated through musical preferences, extending beyond simple self-reports to behavioral actions. Both reactions to unfamiliar music and 'Likes' for specific artists on social media successfully predicte...

This large-scale longitudinal study involving over 22,000 adults demonstrates a powerful, bidirectional relationship between personality and sleep quality. Lower Neuroticism and higher Extraversion were the strongest predictors of better sleep, often outweighing demographic factors. Conversely, l...

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 ...

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...

Research on 514 participants indicates that Openness to Experience and Agreeableness are the strongest predictors of a 'universal-diverse orientation,' or the appreciation of human commonalities and differences. While factors like low Neuroticism and high Conscientiousness also play roles, specif...

This handbook offers a comprehensive and practical guide to major personality assessment tools, combining theoretical foundations with real-world application. Covering widely used instruments, it details their development, administration, scoring, and interpretation, along with psychometric prope...

Humanism represents a profound shift in European thought, marking the transition from the Middle Ages to the Renaissance. By centering human experience rather than strictly divine or supernatural matters, it revived interest in the classical Greek and Roman philosophies that prioritized logic, rh...

To gather diverse perspectives, the GAO collaborated with the National Academies to survey experts across multiple disciplines, including criminology, economics, public health, and statistics. This interdisciplinary approach was paired with a comprehensive literature review of 27 major studies pu...

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 dif...

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, particu...

This study introduces a new model to measure how much our personalities stay the same versus how much they change over time. The findings reveal that while 83% of our core personality traits remain stable throughout life, areas like self-esteem and life satisfaction are much more likely to shift....

This meta-analysis examined links between Big Five personality traits and physical activity across over 60 studies. Extraversion, conscientiousness, and openness showed small positive associations with activity, while neuroticism showed a small negative link; agreeableness was not related. Effect...

This research examines the volunteer process across three distinct stages: antecedents (what motivates a person to serve), experiences (the actual period of service), and consequences (the outcomes for all involved). By analyzing volunteerism through multiple lenses, the study addresses the impac...

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...

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 i...

While personality traits and personal values both predict behavior, they remain distinct psychological constructs. A meta-analysis of 60 studies linking the Five-Factor Model to Schwartz’s Value Theory reveals consistent but moderate correlations, confirming they are not interchangeable. The rese...
