The current study examined whether bystander behaviours in class were associated with being perpetrators of ethnic victimization and whether they moderated the association between disengagement from morality and perpetrating ethnic-based victimization. The sample included 1065 adolescents residing in Sweden (M[subscript age] = 13.12, SD=.42; 55%…

Background: Prescription drug misuse among youth aged 12-18 remains high in the United States. Grounded in Social Norms Theory, school-based curricula have been shown to effectively challenge students' misperceptions of peer norms and safety regarding prescription drug misuse (PDM). Objective: The present study is a quasi-experimental evaluation…

Plant-based dietary choices can help to mitigate climate change. Yet, most people still consume meat. Social identity influences dietary choices. This study tests whether shared identity, pro-veg*n norms, attitudes, and dietary intentions, can be strengthened via a vegan cooking workshop for children. Pupils (N = 155) cooked in small groups (3-6…

Background: Human Papillomavirus (HPV) is the most common sexually transmitted infection. Current guidelines recommend HPV vaccination during adolescence, but vaccination rates remain suboptimal. Efforts are needed to increase vaccination among the catch-up group (individuals aged 18-26 years). Interventions have primarily focused on education,…

Female students are much less likely than their male counterparts to take A levels in certain STEM (Science, Technology, Engineering and Maths) subjects. This is problematic for gender equality but also limits the country's capacity to address the growing national STEM skills shortage. This research was commissioned to design and test the…

Background: Individual-level implementation determinants, such as clinician attitudes, commonly influence the successful adoption of evidence-based practices, but few explicit strategies have been tested with regard to their ability to impact these key mechanisms of change. This paper reports on an initial test of a blended, theoretically-informed…

Hispanics have a disproportionate burden of poorer cancer outcomes. "Promotores" (community health workers) have been shown to be effective in delivering interventions to this population. However, little is known about what aspects of the "promotores" influence the delivery of a cancer education intervention as well what…

Over the last decade, mobile communication has become increasingly available, affordable and accessible even to the poor and disadvantaged at the Bottom of the Pyramid (BOP) in developing countries. This unprecedented connectivity at the BOP introduces not only an untapped group of media users for communication researchers, but also a new hope…

Given the demographic differences among two-year colleges and four-year universities and the relatively limited access to health education and campus-based health resources, this study compares the frequency of limiting dietary fat intake and exercising among two- and four-year college students. A total of 2,265 undergraduate students aged 18-25…

While affiliation with Greek fraternities/sororities and intercollegiate athletic teams is associated with heavier drinking (Meilman et al., 1999), few studies have compared reasons for drinking among these groups. A sample of 1,541 students, identifying as either Greeks or athletes, completed an online survey. Athletes were significantly higher…

Objectives: To examine variable frequencies and relationships between students' intentions and confidence with their intervention. Methods: Incoming freshmen (509 of 1155 students responded) completed a survey 2 months into college. Results: Most (75.2%) students intervened into others' drinking, usually as a caretaker. Students reported more…

The goal of the current study was to assess the efficacy and acceptability of a web-based tutorial (Child Health Matters, CHM) designed to improve school nurses' communications with families about pediatric weight-related health issues. Using a randomized wait-list control design, a nationally representative sample of school nurses was assigned to…

The cross-sectional study investigated South African rural high school learners' choice of sexual abstinence in order to be able to develop tailored health education messages. All Grade 9 learners from one class at each of 10 randomly selected rural high schools participated. The Integrated Model for Motivational and Behavioural Change was used to…

Tobacco smoking is a very important preventable cause of mortality and morbidity, and this is also the case in immigrant populations. Therefore, smoking cessation interventions need to take these groups into account. Insight into the applicability of behavioral smoking cessation interventions for non-Western populations is necessary. The objective…

In this study, it was tested whether attitudes, self-efficacy, social influences and the perception of the school and home environments had different associations with intentions for adolescent non-smokers, occasional smokers and daily smokers. A regression model allowing for separate slopes of social-cognitive and environment variables accounted…
