Efficacy beliefs are important determinants of human behavior. In the context of social cognitive theory, the perception of collective efficacy is closely related to the individual perception of self-efficacy, which is influenced by socio-structural factors such as socioeconomic status (SES). Surprisingly, the relationship between these variables has received little attention in the literature on environmental issues. Within the framework of social cognitive theory, the aim of this study was to investigate whether SES has a direct effect on pro-environmental behavior and whether it has an indirect effect via perceptions of self-efficacy and collective efficacy, in relation to climate change mitigation behavior. An online cross-sectional study was conducted using a quota sample of 1075 participants (51.9% women) aged 18–79 years. Participants reported their SES using objective and subjective measures, perceptions of their own and collective efficacy in mitigating climate change, and the frequency of their pro-environmental behaviors. Structural equation modeling revealed that the model with serial mediation effects of self-efficacy and collective efficacy between SES (both objective and subjective) and pro-environmental behaviors showed a good model fit. As expected, both objective and subjective SES had no direct effect on pro-environmental behavior. Surprisingly, neither objective nor subjective SES had an indirect effect (via efficacy beliefs) on pro-environmental behavior. However, both self-efficacy and collective efficacy were associated with pro-environmental behavior. These findings have practical implications for the development of strategies aimed at enhancing pro-environmental behavior.

On-field aggressive behaviour is often seen on sports fields and numerous theories tried to identify its origins. This study tackled the question of whether the youth athletes in contact and non-contact sports could be differentiated on the basis of the hostile and competitive aggression, and some other characteristics that showed to be related to the aggressive on field behaviour. The study sample comprised 154 of (51% girls) young athletes aged between 10 and 15 years from various contact and non-contact disciplines (wrestling, boxing, taekwondo, football, swimming, athletics, and dance). Participants completed several questionnaires regarding their aggressive behaviour, motivation, anxiety, self-esteem and emotional regulation. Only the competitive, but not hostile, aggression was more present among the youth athletes in contact sports. From all other characteristics, self-esteem, although in a lower extent, predicted affiliation of the non-contact sports group.
