The Influence of Physical Exercise on Adolescent Personality Traits: The Mediating Role of Peer Relationship and the Moderating Role of Parent-Child Relationship

Adolescence is the critical period of the formation for individual personality traits, which would be influenced by numerous factors such as the internal and external environment. In view of physical exercise as an important factor affecting the healthy development of adolescents, whether it would play an important role in the formation of adolescents' personality traits and how it would work deserve further investigation. Based on the Ecological Systems Theory, this study has explored the relationship between physical exercise and adolescents' personality traits, as well as the mediating effect of peer relationship and the moderating effect of parent-child relationship using 9,284 data samples. The regression results show that physical exercise has a significant positive impact on the development of personality traits such as neuroticism, conscientiousness, and agreeableness. Peer relationships exert the mediating effect between physical exercise and adolescents' personality traits. However, parent-child relationship only moderates the effect of physical exercise on conscientiousness and agreeableness.

SENNA Inventory for the Assessment of Social and Emotional Skills in Public School Students in Brazil: Measuring Both Identity and Self-Efficacy

Responding to the need for school-based, broadly applicable, low-cost, and brief assessments of socio-emotional skills, we describe the conceptual background and empirical development of the SENNA inventory and provide new psychometric information on its internal structure. Data were obtained through a computerized survey from 50,000 Brazilian students enrolled in public school grades 6 to 12, spread across the entire State of São Paulo. The SENNA inventory was designed to assess 18 particular skills (e.g., empathy, responsibility, tolerance of frustration, and social initiative), each operationalized by nine items that represent three types of items: three positively keyed trait-identity items, three negatively keyed identity items, and three (always positively keyed) self-efficacy items, totaling a set of 162 items. Results show that the 18 skill constructs empirically defined a higher-order structure that we interpret as the social-emotional Big Five, labeled as Engaging with Others, Amity, Self-Management, Emotional Regulation, and Open-Mindedness. The same five factors emerged whether we assessed the 18 skills with items representing (a) a trait-identity approach that emphasizes lived skills (what do I typically do?) or (b) a self-efficacy approach that emphasizes capability (how well can I do that?). Given that its target youth group is as young as 11 years old (grade 6), a population particularly prone to the response bias of acquiescence, SENNA is also equipped to correct for individual differences in acquiescence, which are shown to systematically bias results when not corrected.

Development of an Inventory Assessing Social and Emotional Skills in Brazilian Youth

Abstract. Whereas the structure of individual differences in personal attributes is well understood in adults, much less work has been done in children and adolescents. On the assessment side, numerous instruments are in use for children but they measure discordant attributes, ranging from one single factor (self-esteem; grit) to three factors (social, emotional, and academic self-efficacy) to five factors (strength and difficulties; Big Five traits). To construct a comprehensive measure for large-scale studies in Brazilian schools, we selected the eight most promising instruments and studied their structure at the item level (Study 1; N = 3,023). The resulting six-factor structure captures the major domains of child differences represented in these instruments and resembles the well-known Big Five personality dimensions plus a negative self-evaluation factor. In a large representative sample in Rio de Janeiro State (Study 2; N = 24,605), we tested a self-report inventory (SENNA1.0) assessing these six dimensions of socio-emotional skills with less than 100 items and found a robust and replicable structure and measurement invariance across grades, demonstrating feasibility for large-scale assessments across diverse student groups in Brazil. Discussion focuses on the contribution to socio-emotional research in education and its measurement as well as on limitations and suggestions for future research.

A Review of the Direct and Interactive Effects of Life Stressors and Dispositional Traits on Youth Psychopathology

Stressors and dispositional traits have been implicated in youth psychopathology; however, the direct effects from stressors or traits alone may be insufficient for explaining maladaptive development. Evidence for the impact of stressors and dispositional traits has largely progressed within separate lines of inquiry, resulting in disunited etiological models and variable empirical support. Existing research on the concurrent effects of stressors and traits has also been hindered by several conceptual issues-including mixed evidence for specificity effects, inconsistent operationalization of stressors, and inadequate coverage of dispositional traits across development-making it difficult to draw conclusions across studies. The current review aims to unify these independent lines of inquiry by evaluating prior research according to three theoretical frameworks: (1) additive, (2) diathesis-stress, and (3) social push models. Implications for assessment, prevention, and intervention efforts in clinical child and adolescent psychopathology are discussed.

Sport participation, screen time, and personality trait development during childhood

This investigation explored the contribution of extracurricular sport and screen time viewing (television viewing and electronic gaming) to personality trait stability and change during childhood. Two independent samples of 3,956 young children (age 6) and 3,862 older children (age 10) were taken from the Longitudinal Study of Australian Children. Parent-reported child sport participation, screen time, and personality traits were measured at baseline and again 24 months later. Young children who were more active recorded more of a decrease in introversion, less of a decrease in persistence, and less of an increase in reactivity, than those who were less active. Older children who were more active recorded less of an increase in introversion and more of an increase in persistence than those who were less active. In addition, young children who continued participation in extracurricular sport had greater intra-individual stability of personality for introversion. These finding suggest that an active lifestyle might help to facilitate desirable personality trait stability and change during childhood.

Who do you think you are? - Personality in eating disordered patients

BACKGROUND

The Five-Factor Model of personality is strongly linked to common mental disorders. Yet the relationship between the lower order personality traits (facets) of the model and eating disorder (ED) features remains unclear. The aim of the study was to explore how patients with non-anorexic ED differ from controls in personality and to examine the ability of personality facets to explain psychopathology.

METHODS

Female patients with non-anorexic ED (N = 208) were assessed on general psychopathology, ED symptoms and personality as measured by the NEO PI-R; and were compared on personality to age-matched female controls (N = 94).

RESULTS

Compared to controls, patients were characterised by experiencing pervasive negative affectivity and vulnerability, with little in the way of positive emotions such as joy, warmth and love. Patients were also significantly less warm and sociable, and exhibited less trust, competence, and self-discipline. Finally, they were less open to feelings, ideas and new experiences, yet more open in their values. Among patients, personality facets explained up to 25% of the variance in ED and general psychopathology.

CONCLUSIONS

ED patients have distinct patterns of personality. Identifying and focusing on personality traits may aid in understanding ED, help therapists enhance the treatment alliance, address underlying problems, and improve outcome.
