Although peer norms significantly influence adolescents' aggressive behaviors, little research compares their effects in online and offline contexts. Specifically, online contexts differ from traditional ones by enabling anonymity and amplifying behavior visibility. These characteristics could alter norm perceptions, reducing or increasing…

Objective: To examine the influence of dynamic and trending descriptive norms on increasing physical activity and decreasing the sedentary behaviors of university students while on campus. Participants: One-hundred fifty-six university students from a Canadian university completed this study. Methods: Participants were randomly assigned to receive…

This study aimed to explore the association between prestige norms of moral disengagement and ethnic bullying among Italian early adolescents. Prestige norms of moral disengagement were also examined as possible moderator of the association between individual prejudice and ethnic bullying. Participants were 742 sixth to eighth graders attending…

Background: Previous studies have shown that when young people witness bullying, perceived social norms of their peer group affect their behavior. However, few studies have examined the specificity of norm misperception (i.e., overestimation of peer antisocial responses and the underestimation of prosocial responses relative to the objective group…

While intergroup contacts and social norms both have important roles in regulating intergroup relations, their effects on intergroup outcomes have mostly been examined independently from each other. The purpose of this longitudinal study was to explore the role of perceived ingroup norms about intergroup contact in the relationships between both…

Background: Relationships exist between perceived peer and own use of alcohol, cannabis, and tobacco, particularly when peers and participants are sex-matched. We investigated sex influences on social norms effects for college students' non-medical prescription drug use (NMPDU). Methods: N = 1986 college students reported on their perceptions of…

This report presents findings from data collected through the Reality Now program, providing a long-term study exploring tobacco and vaping behaviours among Australian secondary school students. Conducted from 2018 to 2024, the program collected nearly 30,000 responses from students in Years 7 to 11. Using a social norms approach (SNA), the…

The aim of our study was to explore students' bystander roles in peer bullying considering the interaction between their individual and contextual characteristics. We included social status goals (popularity, social preference and social insecurity), moral disengagement and peer support as key variables for differentiating bystander behaviour. Our…

This study examines the factors driving student non-compliance with AI use declarations in academic assessments at King's Business School, where 74% of students failed to declare AI usage despite declaration being a requirement of a mandatory coursework coversheet. Utilising the Theory of Planned Behaviour (TPB) as a framework, the research…

Associations between social norms and bullying bystander behaviours have been studied extensively over the years, but the mechanisms by which subjective norms influence bystander behaviours remain unclear. This study is the first to examine whether bystander popularity moderates the association between perceived peer pressure for intervention and…

This study examined variations in the development of classroom aggression popularity norms, as well as the role of homeroom teachers' aggression beliefs and students' perceptions of teachers' support as predictors of such variations. To achieve this goal, a sample of 63 classrooms were assessed at four time points during a school year, in nine…

Purpose: This paper explores the impact of a suite of alcohol culture change interventions implemented by Deakin University in Melbourne, Australia. The interventions were designed to change the alcohol culture at a bi-annual nation-wide university multi-sport competition known as Uni Nationals. This study aims to understand the critical success…

Having its originations in the 1987 UN Brundtland Report and the 1994 Oslo Symposium for sustainable consumption and production (SCP), education for sustainable development (ESD) has taken on global importance. As such, the study's author sought to examine the causal relationships on sustainable consumption behaviour (SCB) of Thai student science…

How others behave (descriptive norm) and what they expect from us (injunctive norm) has a strong influence on how we behave. However, children and adolescents often overestimate the prevalence of negative behavior among their peers. The current study tested whether prompting peer norms for cyberbullying may foster anti-cyberbullying norms in an…

There is a growing interest in the factors influencing bystanders' interventions in school-bullying. However, perceived social norms, beliefs about what others do (perceived descriptive norms), and what others think one should do (perceived injunctive norms) still require attention. The aim of this study was to investigate whether students…
