Mental Health and Cognitive Outcomes in Patients Six Months After Testing Positive Compared with Matched Patients Testing Negative for Covid-19 in a Non-Hospitalized Sample
We aimed to determine the mental health and cognitive outcomes at six months in people who had not been hospitalized with COVID-19 and who had tested positive or negative for COVID-19 in Eastern Ontario, Canada. Participants were matched 1:1 six months following their COVID-19 polymerase chain reaction test. X2, t -test, and Mann-Whitney U tests were conducted to compare self-report and observer-rated mental health and cognitive outcomes between …
Engagement, Attitudes, and Perceptions of Social Media Use
This study seeks to explore the relationship between mental well-being and engagement, attitudes, and perceptions of social media use across adolescents. This study is based on a survey of adolescents ( n = 3,568, mean age = 17.3) conducted in 2020 and 2021. Mental well-being was assessed using the Warwick-Edinburgh Mental Well-being Scale (WEMWBS) and categorized into low, mid-range and high mental well-being. Social media activity was measured …
The social determinants of mental health and disorder
People exposed to more unfavourable social circumstances are more vulnerable to poor mental health over their life course, in ways that are often determined by structural factors which generate and perpetuate intergenerational cycles of disadvantage and poor health. Addressing these challenges is an imperative matter of social justice. In this paper we provide a roadmap to address the social determinants that cause mental ill health. Relying as f…
Digital self-presentation and adolescent mental health
The results of the present study suggest that a heightened focus on self-presentation, which includes behaviours such as seeking feedback, employing strategic self-presentation tactics, and engaging in upward social comparisons, is associated with an elevated risk of reduced mental health

Can Social Media Use Be More Health-Promoting? Description and Pilot Evaluation of a School-Based Program to Increase Awareness and Reflection on the Use of Social Media
Social media plays a significant role in adolescents' lives, with both positive and negative effects. Implementing interventions to mitigate the negative aspects and enhance the positive ones could improve adolescents' well-being. Unfortunately, there is a scarcity of evidence-based interventions available. To fill this gap, we have developed a school-based program based on combining evidence-based and consensus-based approaches, incorporating in…
Heavy social media use and psychological distress among adolescents
Background Despite increasing evidence that social media use is associated with adolescents’ mental well-being, little is known about the role of various factors in modifying the effect of this association during adolescence. This study examined the association between social media use and psychological distress among adolescents and explored whether sex, age, and parental support moderate this association. Methods Data came from a representative…
Longitudinal associations between different types of screen use and depression and anxiety symptoms in adolescents
Background Evidence examining the longitudinal associations between different types of screen behaviours and mental health among adolescents is limited. The present study examined the association between five types of screen behaviours and symptoms of anxiety and depression one year later. This study also assessed how changes in screen time were associated with changes in anxiety and depressive symptoms and whether the observed relationships were…
Predictors of Relationship Satisfaction Across the Transition to Parenthood
The purpose of the study was to describe trajectories of relationship satisfaction across the transition to parenthood, and identify predictors of these trajectories. This study is based on the Norwegian Mother, Father, and Child Cohort Study (MoBa). Mothers (N = 43,517) reported on their relationship satisfaction at five timepoints from 17 weeks gestation to 5 years postpartum, as well as sociodemographic, psychological, and behavioral covariate…
Focus on Self-Presentation on Social Media across Sociodemographic Variables, Lifestyles, and Personalities
Upward social comparison and aspects of self-presentation on social media such as feedback-seeking and strategic self-presentation may represent risk factors for experiencing negative mental health effects of social media use. The aim of this exploratory study was to assess how adolescents differ in upward social comparison and aspects of self-presentation on social media and whether these differences are linked to sociodemographic variables, lif…

H Movement Guidelines and Substance Use among Adolescents
Children and youth are recommended to achieve at least 60 min/day of moderate-to-vigorous physical activity, no more than 2 h/day of recreational screen time, and a sleep duration of 9-11 h/night for 11-13-year-olds or 8-10 h/night for 14-17-year-olds. Meeting the physical activity, screen time, and sleep duration recommendations have previously been associated with substance use among adolescents. However, previous research has mainly examined t…

Air Pollution and Emergency Department Visits for Mental Disorders among Youth
Although exposure to ambient air pollution has been linked to mental health problems, little is known about its potential effects on youth.

Social media use and parent–child relationship
We examined the association between social media use and parent–child relationship quality and tested whether this association is independent of total screen time. Data on 9,732 students (48.4% female) aged 11–20 years were obtained from a provincially representative school‐based survey. Heavy use of social media (daily use of more than 2 hr) was associated with greater odds of negative relationships between mother–daughter (odds ratio [OR] = 1.7…

Adult mental health outcomes of adolescent depression
Santé mentale et maladies mentales des jeunes francophones de 15 à 24 ans
La plupart des maladies mentales apparaissent à l’adolescence ou au début de la vie adulte ; elles influent sur les réussites scolaires, les possibilités et les succès professionnels ainsi que les relations personnelles et peuvent avoir des répercussions tout au long de la vie. Bien que la majorité des jeunes traversent leur adolescence sans problèmes, une proportion suffisamment importante montre toutefois un profil préoccupant dont il faut pren…
Stigma doesn’t discriminate
Physical health stigma appears to be present for both civilians and military personnel, but more so for military personnel. Elements of military culture (e.g., the way care is sought, culture of toughness, strict fitness requirements) as well as the physical demands of the job could be potential predictors of group differences
