Introduction: Personal resources and resources of the sociocultural environment help children and adolescents to successfully cope with challenges in everyday life, which is associated with better individual well-being. SCOUT, the 'Study on Competence development in OUT-of-school settings', investigated whether participation in a summer camp enhanced adolescents' personal resources, well-being, and readiness to contribute to the community.

Methods: The research took place during the Swiss National Jamboree of the Swiss Guide and Scout Movement, a two-week event in the summer of 2022, with a paper-pencil pretest (beginning of the camp - T1) and posttest (end of the camp - T2) survey ( = 607, aged 14-17).

Many teachers report high levels of occupational stress. Teachers' basic need satisfaction is essential for teachers' well-being at work. Social support from school principals is assumed to play an important role for teachers' basic need satisfaction.

In (pre)school, children acquire and deepen their basic motor competencies (BMCs) and interact with peers and friends. BMCs are a central developmental goal in childhood and the prerequisite for participation in sportive aspects of social life. Both motor competencies and social integration are linked to children's health-related quality of life (HRQoL).

Many teachers experience high levels of work-related strain due to time pressure, which over time can lead to various health problems, such as emotional exhaustion. However, there is growing evidence that this could be a reciprocal effect. Moreover, it is known that perceived social support can buffer the negative effects of stress, such as time pressure, on health outcomes.

In preschool, children build new contacts and social relationships with other people. They learn to cooperate with their peers and communicate in groups. In addition to social relationships, basic motor competencies (in German: Motorische Basiskompetenzen (MOBAK)) are also seen as a central developmental goal in early childhood and are necessary for participation in the culture of sports and movement.

Compensatory Health Beliefs (CHBs) are defined as beliefs that the negative consequences of unhealthy behaviours can be compensated for by engaging in healthy behaviours. CHBs have not yet been investigated within a framework of a behaviour change model, nor have they been investigated in detail regarding smoking. Thus, the aim of this study was to investigate on a theoretical basis whether smoking-specific CHBs, as a cognitive construct, add especially to the prediction of intention formation but also to changes in smoking behaviour over and above predictors specified by the Health Action Process Approach (HAPA).

Objective: Compensatory health beliefs (CHBs) are defined as beliefs that negative consequences of unhealthy behaviours can be compensated for by engaging in other health behaviours. CHBs have not yet been investigated in detail regarding smoking. Smoking might cause cognitive dissonance in smokers, if they are aware that smoking is unhealthy and simultaneously hold the general goal of staying healthy.

Objectives: The Transtheoretical Model of behavior change (TTM) postulates that behavior change is a process involving progress through five distinct stages of change (SOC). One of the key components for progress to a later stage is decisional balance (pros and cons of changing to the target behavior). The goal of the present study is to test the two dimensions of decisional balance as postulated in the TTM in the context of exercising behavior.

Objective: Theories of health behavior are usually tested on the between-person level. Associations between variables on the between- and the within-person level, however, can differ substantially. Thus, in order to better understand intrapersonal processes in the domain of health behavior, studies applying within-person analyses are needed.

Objectives: To present selected results on exposure to second-hand smoke and experienced annoyance with second-hand smoke in the Swiss population, particularly in restaurants and in the workplace.

Methods: The data were collected as part of the Swiss Survey of Tobacco Use ("Tobacco Monitoring") commissioned by the Swiss Federal Office of Public Health. It is a representative, continuous survey of tobacco consumption among 14- to 65-year-olds in Switzerland.
