Does outdoor advertising correlate with retail food purchases made by adolescents? A cross-sectional study in Canada
Food marketing plays a substantial role in shaping adolescent diets, having wide-ranging ramifications for health behaviours and outcomes throughout the life course. Yet, there remains a dearth of research about how outdoor advertising as a specific channel of food marketing affects purchasing behaviours. We examine self-reported purchases made at retail food outlets by adolescents as it relates to the availability of outdoor food and beverage ad…
Psychometric properties of an Adapted Climate Change Coping Scale in a sample of Canadian adolescents
A 16-item Adapted Climate Change Coping Scale (CCCS-A) operationalizes coping with thoughts and feelings about climate change into four dimensions. • The dimensions of coping in the CCCS-A were: de-emphasizing, distracting, problem-focused coping, and meaning-focused coping. • The CCCS-A is evidenced as being a reliable and valid instrument. Climate change is a threat to the health and wellbeing of adolescents. Many adolescents express concern, w…

Home learning environment and family socioeconomic status were assessed with parent questionnaires. EF were assumed to be associated with phonological as well a…
Coming to terms with climate change: A glossary for climate change impacts on mental health and well-being
Climate change is a major threat to global health. Its effects on physical health are increasingly recognised, but mental health impacts have received less attention. The mental health effects of climate change can be direct (resulting from personal exposure to acute and chronic climatic changes), indirect (via the impact on various socioeconomic, political and environmental determinants of mental health) and overarching (via knowledge, education…
Exploring the relationships between worry about climate change, belief about personal responsibility, and mental wellbeing among adolescents and young adults
Today's adolescents and young adults experience high levels of media coverage, public opinion, and formal education about climate change. The young people of today are also projected to experience more climate change related extreme events than previous generations. Although adolescents and young adults may worry about the impacts of climate change and feel personal responsibility to reduce climate change, there is little known about how this rel…

Therapeutic Potential of Psilocybin for Treating Psychological Distress among Survivors of Adverse Childhood Experiences: Evidence on Acceptability and Potential Efficacy of Psilocybin Use
Survivors of adverse childhood experience are at elevated risk for psychological distress. In recent years, renewed interest in psychedelic medicine has highlighted the therapeutic potential of psilocybin for those who have experienced childhood adversity. However, recreational psilocybin use remains illegal and access to approved therapies is difficult. Such use provides an opportunity to explore the therapeutic potential of psilocybin for psych…
Intake of Fruits, Vegetables, and Sugar-Sweetened Beverages among a Sample of Children in Rural Northern Ontario, Canada
There is evidence to suggest that dietary intake of children differs by rural/urban place of residence: rural children may have a higher intake of foods high in fat and sugar than those living in urban environments. The aim of this study was to examine the intake of fruits and vegetables (FV) and the frequency of sugar-sweetened beverage (SSB) consumption, among a sample of rural children in Northern Ontario, Canada, in two different seasons.

Measurement Invariance of the WHO-5 Well-Being Index: Evidence from 15 European Countries
(1) Background: The World Health Organization (WHO)-5 Well-Being Index has been used in many epidemiological studies to assess adolescent mental well-being. However, cross-country comparisons of this instrument among adolescents are scarce and, so far, no good-fitting, common invariant measurement model across countries has been reported. The present study aims to evaluate and establish a version of the WHO-5 Well-Being Index that allows for a va…
Examining how children's gender influences parents’ perceptions of the local environment and their influence on children's independent mobility
Physical inactivity among children is a public health concern. Children's ability to travel independently is associated with increased physical activity and social connectedness. Consequently, it is concerning that children's independent mobility has decreased in recent years. Studies have highlighted that rates of independent mobility vary by gender; this study analyzed how correlates of independent mobility vary between boys (n = 476) and girls…
Health Outcomes Following Childhood Maltreatment: An Examination of the Biopsychosocial Model
Child maltreatment constitutes a notoriously large problem within the healthcare field and is associated with significant biological, psychological, and social consequences across the lifespan.

Do regionally targeted lockdowns alter movement to non-lockdown regions? Evidence from Ontario, Canada
Regionally targeted interventions are being used by governments to slow the spread of COVID-19. In areas where free movement is not being actively restricted, there is uncertainty about how effective such regionally targeted interventions are due to the free movement of people between regions. We use mobile-phone network mobility data to test two hypotheses: 1) do regions targeted by exhibit increased outflows into other regions and 2) do regions…
Analyzing differences between spatial exposure estimation methods: A case study of outdoor food and beverage advertising in London, Canada
Examining how changes in provincial policy on vape marketing impacted the distribution of vaping advertisements near secondary schools in London, Ontario
The provincial ban of vaping advertisements in select retail settings significantly reduced the number of vaping advertisements in the areas surrounding secondary schools in London, Ontario. The ban also reduced socio-demographic inequities in youths' potential exposure to marketing of vaping products. Continued monitoring of the geographic accessibility and promotion of vaping products is warranted
Cross-National Time Trends in Adolescent Mental Well-Being From 2002 to 2018 and the Explanatory Role of Schoolwork Pressure
PURPOSE: Previous research has shown inconsistent time trends in adolescent mental well-being, but potential underlying mechanisms for such trends are yet to be examined. This study investigates cross-national time trends in adolescent mental well-being (psychosomatic health complaints and life satisfaction) in mainly European countries and the extent to which time trends in schoolwork pressure explain these trends. METHODS: = 1.63) across five H…
