Kairos study protocol: a multidisciplinary approach to the study of school timing and its effects on health, well-being and students' performance.

Recent evidence from chronobiology, chssronomedicine and chronopsychology shows that the organisation of social time (e.g., school schedules) generally does not respect biological time.

Mediation effect of emotional self-regulation in the relationship between physical activity and subjective well-being in Chilean adolescents.

Adolescents' subjective well-being and physical activity have been found to be correlated in previous studies. However, the underlying mechanisms of this relationship, especially the potential contribution of emotional self-regulation, have received little attention. This study aims to investigate the extent to which emotional self-regulation mediates the association between adolescent physical activity habits and their subjective well-being.

Sibling Bullying, School Bullying, and Children's Subjective Well-Being Before and During the COVID-19 Pandemic in Indonesia.

The aims of this study are threefold. The first aim is to examine the prevalence of sibling and school bullying before and during the COVID-19 pandemic in Indonesia. The second aim is to investigate the subjective well-being (SWB) of children who were bullied or never bullied before and during COVID-19.

Physical activity habits and their relationship with sociodemographic factors in Chilean adolescents.

Physical activity plays an important role in the well-being and development of adolescents. Physical activity habits expressed in terms of frequency and duration are consistently associated with sociodemographic factors such as age, gender, and socioeconomic status. However, there is less evidence of the relationship between the type and context of physical activity in adolescents.

Subjective well-being of children and adolescents during the COVID-19 pandemic in Indonesia: two data collections.

This paper examines the subjective well-being (SWB) of children and adolescents (10‒18 years old) during the COVID-19 pandemic in Indonesia for two periods (May to July 2020 and March to May 2021), using cross-sectional data from two distinct samples of  = 1,011 ( age = 14.61) and  = 1,640 ( age = 14.86), respectively.

The Moderating Role of Sociodemographic Factors in the Relationship between Physical Activity and Subjective Well-Being in Chilean Children and Adolescents.

Background: The relationship between physical activity habits and well-being is widely recognized; however, the interaction that these variables have with sociodemographic factors throughout life is only partially addressed in the literature, particularly in children and adolescents. The aim of this article is to analyze the moderating effect of sociodemographic factors and the possible interaction of these moderations in the relationship between physical activity and subjective well-being in children and adolescents.

Methods: This cross-sectional study considered a sample of 9572 children and adolescents from 10 to 19 years of age, students of primary and secondary schools in all regions of Chile.

The Structure of Children's Subjective Well-being.

Research on children's quality of life and subjective well-being has advanced over the past decade largely as a result of developments in childhood theory, children's rights legislation, and the shift toward positive social science. However, in line with the uncertainty regarding the conceptualization of subjective well-being, the structural configuration of children's subjective well-being has not been considered in the literature. In the current study, we present and test a model of children's subjective well-being, which includes global (context-free items assessing overall and general well-being, without reference to a specific aspect of life) and specific (domain-based items assessing a specific aspect of life) cognitive components, and positive and negative affect.

Gratitude at Work Prospectively Predicts Lower Workplace Materialism: A Three-Wave Longitudinal Study in Chile.

Materialism at work refers to a higher importance attached to extrinsic (e.g., money, fame, image) versus intrinsic (self-development, affiliation, community participation) employees' 'aspirations'.

Mediation of Problematic Use in the Relationship Between Types of Internet Use and Subjective Well-Being in Schoolchildren.

Subjective well-being is a broad category of phenomena that includes people's emotional responses, domain satisfactions, and global judgments of life satisfaction. This research investigates how schoolchildren's subjective well-being is affected by the different types of technology use, in personal contexts, and, concurrently, whether these effects are different when the use of technology is problematic. The central hypotheses are as follows: (1) the use of the Internet affects the subjective well-being of schoolchildren negatively only when this use is problematic and (2) the effect on subjective well-being is different according to the type of Internet use.

Peer Relatedness, School Satisfaction, and Life Satisfaction in Early Adolescence: A Non-recursive Model.

Cumulative evidence suggests that, for children and adolescents, peer relatedness is an essential component of their overall sense of belonging, and correlates with subjective well-being and school-based well-being. However, it remains unclear what the underlying mechanism explaining these relationships is. Therefore, this study examines whether there is a reciprocal effect between school satisfaction and overall life satisfaction (Hypothesis 1), and whether the effect of peer relatedness on life satisfaction is mediated by school satisfaction (Hypothesis 2).

Subjective Well-Being in Early Adolescence: Observations from a Five-Year Longitudinal Study.

This article aims to redress the lack of longitudinal studies on adolescents' subjective well-being (SWB) and highlight the relevance of knowledge deriving from such research in designing public policies for improving their health and wellbeing in accordance with the stage of development they are in. To achieve this, the evolution of SWB during early adolescence (in adolescents aged between 10 and 14 in the first data collection) was explored over a five year period, considering boys and girls together and separately. This involved comparing different SWB scales and contrasting results when considering the year of data collection versus the cohort (year of birth) participants belonged to.

The relation between subjective well-being and career aspirations amongst a sample of adolescents in low socioeconomic status communities in Cape Town.

The study aimed to determine the relation between adolescents' subjective well-being and career aspirations. The study further aimed to determine the extent to which social support mediates this relation. The sample comprised 1082 adolescents in Grades 8-11, selected from schools located in low socioeconomic status communities in Cape Town, South Africa.

Subjective Well-Being Decreasing With Age: New Research on Children Over 8.

An increasing number of scientific publications have provided data from different countries suggesting subjective well-being (SWB) continuously decreases during adolescence. A review of these publications reveals authors have used dissimilar scales in diverse countries. Using data from the international Children's Worlds project (N = 48,040), involving 15 countries, a comparative analysis was performed to determine how mean scores evolve with different SWB scales from the age of 8 onwards.
