Novel Approach

Abstract In the current study, we set out to examine the viability of a novel approach to modeling human personality. Research in psychology suggests that people’s personalities can be effectively described using five broad dimensions (the Five-Factor Model; FFM); however, the FFM potentially leaves room for improved predictive accuracy. We propose a novel approach to modeling human personality that is based on the maximization of the model’s predictive accuracy. Unlike the FFM, which performs unsupervised dimensionality reduction, we utilized a supervised machine learning technique for dimensionality reduction of questionnaire data, using numerous psychologically meaningful outcomes as data labels (e.g., intelligence, well-being, sociability). The results showed that our five-dimensional personality summary, which we term the “Predictive Five” (PF), provides predictive performance that is better than the FFM on two independent validation datasets, and on a new set of outcome variables selected by an independent group of psychologists. The approach described herein has the promise of eventually providing an interpretable, low-dimensional personality representation, which is also highly predictive of behavior.

Novel Approach

In the current study, we set out to examine the viability of a novel approach to modeling human personality. Current research in psychology suggests that people’s personalities can be effectively described using five broad dimensions (the Five-Factor Model; FFM); however, the FFM has been criticized for its relatively limited predictive ability. We propose a novel approach to modeling human personality that is based on the maximization of the model’s predictive accuracy. Unlike the FFM, which performs unsupervised dimensionality reduction, we utilized supervised machine learning techniques for dimensionality reduction of questionnaire data, using numerous psychologically meaningful outcomes as data labels (e.g., intelligence, well-being, sociability). The results showed that our five dimensional personality summary, which we term the Predictive Five (PF), provides predictive performance that is superior to the FFM in independent validation datasets, and on a new set of outcome variables selected by an independent group of psychologists. Furthermore, we examine the between-participants’ replicability of the PF representation and show that the PF has good test-retest reliability, and as such provides an important addition to the psychologists' toolbox. The approach described herein has the promise of providing an interpretable low-dimensional personality representation, which is also predictive of behaviour.

The measurement of health-related quality of life (HRQOL) in children has witnessed significant international growth over the past decade in an effort to improve pediatric health and well-being, and to determine the value of health-care services. In order to compare international HRQOL research findings across language groups, it is important to demonstrate factorial invariance, i.e., that the items have an equivalent meaning across the language groups studied. This study examined the factorial invariance of child self-reported HRQOL across English- and Spanish-language groups in a Hispanic population of 2,899 children ages 8–18 utilizing the 23-item PedsQL™ 4.0 Generic Core Scales. Multigroup confirmatory factor analysis (CFA) was performed specifying a five-factor model across language groups. The findings support an equivalent 5-factor structure across English- and Spanish-language groups. Based on these data, it can be concluded that children across the two languages studied interpreted the instrument in a similar manner. The multigroup CFA statistical methods utilized in the present study have important implications for cross-cultural assessment research in children in which different language groups are compared.

Research on self–compassion, which is defined as being understanding and kind to oneself when confronted with negative experiences, has produced an impressive number of articles in recent years. This research shows that individual differences in self–compassion, as measured by the Self–Compassion Scale (SCS), are positively related to life satisfaction, health and social functioning. However, a critical and systematic test of self–compassion from a personality perspective has not yet conducted so far. In the present study ( N = 576), we (i) tested the factor structure of the SCS, (ii) examined the distinctiveness of self–compassion with regard to the five–factor model of personality, focusing on neuroticism, and (iii) tested the incremental predictive power of self–compassion beyond the five–factor model in the context of life satisfaction. Confirmatory factor analyses supported a two–factor plus six facets solution of self–compassion (a positive factor and a negative factor). Additional analyses revealed that the negative factor was redundant with facets of neuroticism ( rs ≥ .85), whereas the positive factor had some unique variance left. However, neither the negative factor nor the positive factor could explain substantial incremental variance in life satisfaction beyond neuroticism. Recommendations for how to use the SCS are provided, and the future of research on self–compassion is discussed. Copyright © 2017 European Association of Personality Psychology

This study focuses on assets related to Sustainable Development Goals (SDGs), which are the most recent aspect of the Socially Responsible Investment framework and have caught the attention of investors due to their investment opportunities as well as the global challenges that can be achieved. The profitability of developing an investment strategy is shown based on the value of the alphas obtained from the estimation of the Fama-French five-factor model when compared to an equally weighted portfolio, even when transaction costs are taken into consideration. In addition, it is proven that investors should focus their investments on two main SDGs: Good health and well-being (Goal 3) and Industry, innovation and infrastructure (Goal 9).

The Usa

Because of the impressive replicability of the Five‐Factor Model (FFM) in adult personality psychology, developmental psychologists have recently begun a search for the antecedents of these five adult dimensions in childhood. The FFM originates in rating scales applied to ‘personality words’, notably adjectives, selected from dictionaries. To test the explanatory power of the FFM as a model for individual differences in childhood, we used a different source for the lexicon of personality. Parents of children aged 3, 6, 9, and 12 years were asked simply ‘to describe your child’. The audiotaped interviews were transcribed literally and then coded using an elaborate coding scheme. We here describe data from three of the countries involved in this cross‐cultural project (Holland, Belgium, and Greece). The data are the results of coding free descriptions for a total of 186 3‐year‐olds and 229 9‐year‐olds. These data represent the first phase of a four‐phase project that includes researchers from The Netherlands, Belgium, Greece, Poland, Germany, the USA, and China. Results from this first phase were very similar over the participating countries although there were some interesting culture‐specific differences. In the second phase, questionnaire items based on the free descriptors in each category of the coding scheme will be written by the research teams. Such items will be rated by new samples of parents. Factor analyses will reduce the item pool to about one hundred items. These will then be given to new samples of parents of children of the ages indicated above. In the last phase, the factor structures will be compared across cultures and be analysed for their resemblance to the FFM, as well as other models of the structure of temperament and personality in childhood.

Five Factors

The relationships between the five-factor model of personality, subjective well-being, and social adaptation were examined in two Spanish groups, one of 112 undergraduate students and one of 177 participants from the general population. Analyses showed a clear pattern of low but positive associations among scores on well-being, social adaptation, and four of the five factors of personality (Extraversion, Agreeableness, Conscientiousness, and Emotional Stability), very similar to those obtained by previous research in the American context.

In contrast to mean–level comparisons, age group differences in personality trait variance have received only passing research interest. This may seem surprising because individual differences in personality characteristics are exactly what most of personality psychology is about. Because different proposed mechanisms of personality development may entail either increases or decreases in variance over time, the current study is exploratory in nature. Age differences in variance were tested by comparing the standard deviations of the five–factor model domain and facet scales across two age groups (20 to 30 years old versus 50 to 60 years old). Samples from three cultures (Estonia, the Czech Republic and Russia) were employed, and two methods (self–reports and informant–reports) were used. The results showed modest convergence across samples and methods. Age group differences were significant for 11 of 150 facet–level comparisons but never consistently for the same facets. No significant age group differences were observed for the five–factor model domain variance. Therefore, there is little evidence for individual differences in personality characteristics being systematically smaller or larger in older as opposed to younger people. We discuss the implications of these findings for understanding personality development. Copyright © 2015 European Association of Personality Psychology

Bond Characteristics

Social structures are critical to the success of many species and have repercussions on health, well-being, and adaptation, yet little is known about the factors which shape these structures aside from ecology and life history strategies. Dyadic bonds are the basis of all social structures; however, mechanisms for formations of specific bonds or patterns in which individuals form which types of bonds have yet to be demonstrated. There is a variety of evidence indicating personality may be a factor in shaping bonds, but this relationship has not been explored with respect to bond components and is yet to be demonstrated in dolphins. This study utilizes a captive population in a naturalistic environment to test for correlation between similarity within the dyad along each personality factor and the strength of the dyad’s bond characteristics. Personality was assessed using a Five Factor Model questionnaire. Dyadic bond strength and characteristic qualities were determined through an exploratory factor analysis to group behaviors recorded via underwater opportunistic focal-follow video. Discovered bond components differed from previous studies and were termed affiliative support, sociosexual, and conflict play. Individuals who differed in Extraversion and Neuroticism displayed greater levels of bonding. This study expands our understanding of the formation of bonds between individuals and the evolution of social structure. Furthermore, it better equips us for making informed environmental policy decisions and improving captive animal care.

Demographic Background

The Five-Factor model is widely accepted as a robust model of personality that influences workplace behaviour and performance. Given evidence of persistent skills gaps in Australia, it is important to explore personality traits in business graduates to understand whether they have the necessary characteristics to enable the country to perform successfully nationally and to compete on a global level, particularly during periods of economic uncertainty. This study examines personality traits in 674 Australian business graduates, using the Ten-Item Personality Inventory (TIPI), and variations in traits across demographic/background characteristics. The results indicate that graduates are relatively high in extroversion, conscientiousness and emotional stability and low in openness and agreeableness. Some gender differences were apparent. The findings are largely positive for organizational performance, but raise concern for organizational well-being, effective leadership and innovativeness. There is some alignment between the findings and documented deficiencies in graduate performance, highlighting areas for intervention. Strategies for managing typical traits in business graduates and their potential impact on prevalent skills gaps are discussed for both professional and education practitioners.
