The Inclusion of Other-Sex Peers in Peer Networks and Sense of Peer Integration in Early Adolescence: A Two-Wave Longitudinal Study.

The main goal of the analysis presented in this paper is to examine the dynamics of including other-sex peers in the peer networks of early adolescents, aged 11 (at T1) and 13 (at T2), and the relationship between sex heterophily and changes in the sense of peer integration. The analysis was conducted using the Latent Difference Score (LDS) model with data from a representative nationwide longitudinal study in Poland (n = 5748). With reference to the dynamics related to the heterophilic process, the research confirmed that at the beginning of grade 5 of primary school, heterophily is still relatively rare, yet towards the end of early adolescence, there is a gradual shift, more strongly in girls, towards breaking through the strictly same-sex segregation and embarking on heterophilic relationships.

Cyberbullying and its protective and risk factors among Polish adolescents.

Stressful Life Events, Cognitive Biases, and Symptoms of Depression in Young Adults.

Although the link between stressful experiences and depression has been supported in numerous studies, the specific mechanisms of this relationship are still unclear. Cognitive theories of depression postulate that the influence of stress on depression may be modified by cognitive factors. The aim of the present study was to examine the interplay between negative life events, cognitive vulnerability factors, and depressive symptoms.

Cortisol Awakening Response, Self-Reported Affect and Exam Performance in Female Students.

The purpose of the study was to find whether there were differences in cortisol awakening response (CAR) between a neutral day and an exam day in a group of female students and to explore possible relationships between CAR, self-reported affect, and exam performance. A group of 25 female students took samples of their saliva using Salivettes at the moment of waking and after 30 min. They then described their affect using the PANAS scale.
