Coping With Covid‐19's Demanding Collective Goals: Is a Normative Context in Favour of Governmental Measures Related to Social Cohesion?
The measures to limit COVID‐19 and the pandemic had deleterious effects on social cohesion. We propose that perceived clarity and coherence of governmental measures and perceived majority support of these measures together create a normative context that shapes social cohesion. Using a representative sample of adult Canadians ( N = 1180) and a longitudinal design, we aim to (1) identify profiles of perceived clarity, coherence and majority suppor…
Modeling Heterogeneity in the Long-Term Trajectories of Individuals’ Well-Being
Very little is known about how long-term well-being trajectories vary across populations. Using data from 45,160 adults in New Zealand (62% women, M age = 41 years) surveyed annually over 13 years, we identified latent trajectories for belongingness, social support, self-esteem, and life satisfaction. Through a group-based trajectory modeling approach, we found five trajectory groups: low (3%–5%), moderate (11%–17%), moderate-high (29%–32%), high…
Beyond what meets the eye: Unveiling dynamics of compliance with preventive measures in the Covid-19 era
Previous longitudinal studies identified variability in compliance with COVID-19 preventive measures, noting the heightened sensitivity of the least compliant groups to situational factors like easing restrictions. However, they overlooked other forms of variability inherent in compliance behaviour. Hence, we investigated compliance with social distancing and staying-at-home measures, and its dynamic nature, along with its association with social…
Sleep duration and quality trajectories during the early days of the Covid-19 pandemic: A Canadian nationally representative study
In our study, we found no convincing evidence that sleep health indicators deteriorated during the first wave of COVID-19 in Canada. The overall stability of sleep suggests that sleep is likely governed by factors that remained stable
Who's To Blame for the Covid-19 pandemic? Perceptions of responsibility during the crisis using text mining and latent Dirichlet allocation
The spread of the contagious COVID-19 virus was quickly followed by an outbreak of explanations and discourses trying to make sense of the crisis. The goal of this paper is to track the changing dynamics of blame attribution and scapegoating in the Canadian population as the COVID-19 pandemic unfolds, with a particular emphasis on the influence of evolving public health measures. The study uses data from a longitudinal survey conducted with a rep…
Trajectories of health behaviors during the Covid-19 pandemic: A longitudinal analysis of handwashing, mask wearing, social contact limitations, and physical distancing
AIM: This study aimed to investigate the associations between health behavior adherence and psychological factors during the COVID-19 pandemic, with a particular focus on identifying trajectories of handwashing, mask wearing, social contact limitations, and physical distancing. METHODS: We employed a multi-trajectory group-based approach to analyze data from 6026 Belgian residents, including 60% women, with an average age of 52.65. Data were coll…

Diseases of despair in early adulthood: The complex role of social relationships
Diseases of despair," most prominently depressive and substance-related problems, diminish the prospects of many young adults, especially those with lower levels of education. Yet many young adults in that situation avoid these problems. Close relationships are thought to be a key factor underpinning risk and resilience among this group. To examine this premise, this study explored links, beyond potential confounders assessed in adolescence, betw…
Social contagion and high school dropout: The role of friends, romantic partners, and siblings
Social contagion theories suggest that adolescents in relationships with same-age high school dropouts should be at a greater risk of dropping out themselves. Yet, few studies have examined this premise, and none have considered all potentially influential same-age intimates, focusing instead on only either friends or siblings. Moreover, a key influence in adolescents’ social worlds, romantic partners, has been ignored. The goal of this study was…
Parental Control and Conflicts in Adolescence: A Cross-National Comparison of the United States, Canada, Mexico, France, and Italy
This study investigated parental behavioral control, disciplinary style, and parent-youth conflicts in five countries: The United States, Canada, Mexico, France, and Italy. A self-report questionnaire was applied to 1,751 adolescents and their parents. Results indicate that, after controlling for possible confounding variables, parenting in the United States and Canada was characterized by reduced requirements and rules and a disciplinary style m…
Parental Characteristics Associated With Childcare Use During the First 4 Years of Life: Results From a Representative Cohort of Québec Families
Interplay between Friends' Aggression and Friendship Quality in the Development of Child Aggression during the Early School Years
The aim of this study was to investigate the unique and combined role of friendship quality and friends' aggression in regard to the persistence of young children's physical aggression from kindergarten to grade 2. The sample included 1555 children (808 girls) assessed annually using teacher ratings. Two theoretical perspectives (i.e., the social learning and the social bonding perspectives) served as frameworks to guide the analyses and interpre…
Testing the developmental distinctiveness of male proactive and reactive aggression with a nested longitudinal experimental intervention
An experimental preventive intervention nested into a longitudinal study was used to test the developmental distinctiveness of proactive and reactive aggression. The randomized multimodal preventive intervention targeted a subsample of boys rated disruptive by their teachers. These boys were initially part of a sample of 895 boys, followed from kindergarten to 17 years of age. Semiparametric analyses of developmental trajectories for self‐reporte…
Méthodes d'analyse du changement fondées sur les trajectoires de développement individuelle: Modèles de régression mixtes paramétriques et non paramétriques[1]
Longitudinal Methods Based on Individual Development Trajectories - Parametric and Non Parametric Mixed Models: Generalized linear mixed models encompass a variety of modern longitudinal analytic approaches based on individual developmental trajectories. These models overcome many important problems inherent to other traditional analysis of longitudinal data. They all rely on two basic levels: the lower one express, through a set of parameters, t…
Trajectories of Prosocial Behavior and Physical Aggression in Middle Childhood: Links to Adolescent School Dropout and Physical Violence
Trajectories of prosocial behavior and physical aggression between 6 and 12 years of age were identified for a sample ( N =1,025) of males. The trajectories were then used to predict school dropout and physical violence at age 17. Using a group‐based semi‐parametric method, two trajectories of prosociality (low and moderate declining) and three trajectories of physical aggression (low, moderate, and high declining) were obtained. Only a small min…

Parenting, Peer Orientation, Drug Use, and Antisocial Behavior in Late Adolescence: A Cross-National Study
Adolescents' Relationships with Members of the Extended Family and Non-related Adults in Four Countries: Canada, France, Belgium and Italy
This study examines the relationships that adolescents from Canada (province of Quebec), France, Belgium, and Italy have with members of their extended family and non-related adults in their social milieu. The sample of 593 subjects was composed of boys and girls from three age groups, ranging from 11 to 18 years. In each country, subjects came from a large city (Montreal, Brussels and Rome) or from a small city of less than 30,000 inhabitants. T…
