Conscientiousness has consistent and robust associations with a large set of key student outcomes. Thus, to understand the extent to which conscientiousness could be leveraged to support students' learning, achievement, and well-being, it is important to ascertain whether conscientiousness could be strengthened by means of interventions. To narrow…

The Big Five has dominated personality-performance literature, but within the overarching Five Factor Theory characteristic adaptations can be more contextually specific and better predictors of performance. Hardiness, defined as a worldview, is one such characteristic that has shown utility predicting performance when measured in addition to and…

Researchers, theorists, and practitioners have expressed a renewed interest in the longitudinal dynamics of personality characteristics in adulthood, including organic life span trajectories and their amenability to volitional change. However, this research has apparently not yet expanded to include the Dark Triad (psychopathy, narcissism,…

Military service is a life course pathway that defines the transition to adulthood for approximately three to five percent of young adult men and one percent of women. Though few young adults pursue this pathway, the military provides a unique look at the benefits and costs of selecting a highly regimented, segregated, and potentially dangerous…

This paper has two objectives: (1) presenting recent advances in personality theory whereby personality traits are conceptualized within a framework that focuses on the dynamic interactions of behaviour, biology, context, and states, and (2) discussing the implications of these developments for measurement and medical selection. We start by…

We describe 2 frameworks in which personality dimensions relevant to health, such as Conscientiousness, can be used to inform interventions designed to promote health aging. First, contemporary data and theory do not suggest that personality is "immutable," but instead focus on questions of who changes, in what way, why, when, and how.…

Perfectionism is a multidimensional personality construct salient for international students; they are known to be likely high achievers in their home country and face several acculturative challenges after crossing national borders. This study examined whether perfectionist types changed during cross-national transitions in a sample of 227…

Considerable evidence suggests that personality traits may be changeable, raising the possibility that personality traits most linked to health problems can be modified with intervention. A growing body of research suggests that problematic personality traits may be altered with behavioral intervention using a bottom-up approach. That is, by…

We examined change and stability of the 3 personality types identified by Block and Block (1980) and studied their links with adjustment and relationships. We used data from a 5-wave study of 923 early-to-middle and 390 middle-to-late adolescents, thereby covering the ages of 12-20 years. In Study 1, systematic evidence for personality change was…

Moral identity can orient one's behaviors when exhibiting any kind of moral behavior. In this study, the moral identities of young adults are analyzed to a certain extent. For this purpose, the "interpretative phenomenological pattern" and "grounded theory" models are used as qualitative survey models. The study group for…

The present study investigates the link between personality traits (OCEAN Personality test), emotional intelligence (EI) (Trait Emotional Intelligence Questionnaire) and the notion of "feeling different" while using a foreign language among 102 Polish-English bilinguals and Polish L2 users of English who were immersed in a foreign language and…

People tend to attach less value to a good if they know a delay will occur before they obtain it. For example, people value receiving $100 dollars tomorrow more than receiving $100 in 10 years. We explore one reason for this tendency (due to Derek Parfit, 1984): In terms of psychological properties, such as beliefs, values, and goals, the decision…

An adequate theory of happiness or subjective well-being (SWB) needs to link at least three sets of variables: stable person characteristics (including personality traits), life events and measures of well-being (life satisfaction, positive affects) and ill-being (anxiety, depression, negative affects). It also needs to be based on long-term data…

Although the stability and changeability of personality has long been debated, many studies now agree that personality changes over the life course. Although the changes in rank-order and mean-level stability are well established, the stability in personality type membership during adolescence is not yet clear. Little research has been conducted…

The present study addresses the issue of age differences in 5 personality domains across the life span in a cross-sectional study. In contrast to most previous studies, the present study follows a methodologically more rigorous approach to warrant that age-related differences in personality structure and mean level can be meaningfully compared. It…
