Objectives: The 12-item Self-Compassion Scale–Short Form (SCS–SF) is a widely used instrument for the assessment of self-compassion. To date, there have been few examinations of this instrument’s psychometric properties, particularly across nations and languages. Therefore, we used data from the Body Image in Nature Survey (BINS) to assess measurem...

Objectives The 10-item Child and Adolescent Mindfulness Measure (CAMM) is widely used to measure dispositional mindfulness among youth. Recognizing the need for brief tools to minimize time burden on participants and reduce study costs, the present study aimed to validate a short form of the CAMM (CAMM-5-FR), a 5-item derived version of the origina...

The Satisfaction With Life Scale (SWLS) is a widely used self-report measure of subjective well-being, but studies of its measurement invariance across a large number of nations remain limited. Here, we utilised the Body Image in Nature (BINS) dataset–with data collected between 2020 and 2022 –to assess measurement invariance of the SWLS across 65...

Dating violence victimization (DVV) is a prevalent public health problem with harmful consequences among adolescents. Pornography use has been identified among the factors associated with DVV. However, most studies have relied on cross-sectional designs, limiting the ability to determine temporal relationships between these variables. The present s...

Despite recurring calls for diversity and inclusion in adolescent sexuality research, our understanding of adolescents’ sexual experiences beyond heteronormative vaginal intercourse remains limited. The current study examined orgasm (during masturbation and with a partner) and sexual behaviors (providing and receiving manual and oral stimulation) i...

To date, no study has examined whether the presence of a facility dog during forensic interviews assists children in sharing their abuse accounts, without altering the non-suggestive behaviors desired by the investigators and children. This study's purpose was to compare 92 forensic interviews conducted by the same investigators, with and without a...

Detachment from nature is contributing to the environmental crisis and reversing this trend requires detailed monitoring and targeted interventions to reconnect people to nature. Most tools measuring nature exposure and attachment were developed in high-income countries and little is known about their robustness across national and linguistic group...

Background Child maltreatment is a significant social problem impacting both health and society, with severe and enduring consequences. Certain children, such as those with neurodevelopmental conditions like autism, may be more at risk of experiencing maltreatment. However, little research has examined the characteristics of these children. This st...

Child maltreatment poses serious consequences, while sports participation among adolescents offers a potential avenue for mitigating such consequences. This study, based on self-determination theory (SDT), examines the associations among child maltreatment, sports motivation (intrinsic and extrinsic), and satisfaction or frustration of basic psycho...

First Nations children are overrepresented in child protection (CP) throughout the spectrum of services across Canada. The mechanisms through which this overrepresentation occurs have remained partly elusive to empirical support, although certain caregivers’ and living environment’s characteristics appear to influence specific CP decisions. This st...

Introduction Professional and student-athletes are at risk of developing symptoms of eating disorders (ED), including drive for thinness and muscularity due to personal risk factors (e.g., low self-esteem) and sport-specific characteristics (e.g., sport requirements). However, limited studies have focused on ED symptoms among NextGen athletes (iden...

Child maltreatment has been a prominent topic on the political agenda for the past decade. However, while there are several types of interventions that can potentially benefit the prevention of child maltreatment, uncertainties remain regarding the transferability of these interventions to different contexts and their overall impact. Consequently,...

Child maltreatment is a global concern that profoundly affects individuals throughout their lives. This study investigated the relationships between various forms of child maltreatment and behavior problems involving internalization and externalization during adolescence. Data obtained from a diverse sample of 1802 Canadians aged 14–18 years was us...

Background The COVID-19 pandemic has been associated with increased body dissatisfaction and disordered eating behaviors in adolescents. To better understand these associations, this study tested an explanatory model in which appearance-focused social media use, internalization of social media pressure, and mindfulness abilities mediated the relati...

Detachment from nature is contributing to the environmental crisis and reversing this trend requires detailed monitoring and targeted interventions to reconnect people to nature. Most tools measuring nature exposure and attachment were developed in high-income countries and little is known about their robustness across national and linguistic group...

Objectives Childhood cumulative trauma (CCT) has consistently been associated with relationship dissatisfaction in adulthood. Early parenthood is a challenging context where partners’ vulnerabilities, such as CCT history, tend to be exacerbated and further decrease relationship satisfaction. However, dyadic studies are lacking and the mechanisms th...

Although exercise is generally considered a healthy lifestyle habit, it may be problematic for some people. This has led to growing research on compulsive exercise-an uncontrollable urge for physical activity despite its deleterious effects. A maintenance model of compulsive exercise has been developed for adults exhibiting weight and shape concern...

The pandemic revealed and aggravated inequalities between families, particularly related to family–work balance. A more equitable distribution of tasks seems to promote family–work balance. Certain policies and strategies, beyond telework, that may facilitate this balance need to be developed for and with employees.

Through sexual exploration, adolescents learn that they are sexual beings with choices, desires, and are deserving of pleasure, which corresponds to sexual subjectivity. However, the two measures of this construct (i.e., Female Sexual Subjectivity Inventory and Male Sexual Subjectivity Inventory) have not been validated with younger adolescents and...

Online technologies could play an important role in the sexual development of adolescents as they watch more pornography than before. Pornography may relate to adolescents’ perceptions of their bodies, especially among those identifying as a sexual and/or gender minority (SGM) as they have an increased risk of body image concerns compared to their...

Aim: Every year, about 5% of children in Norway experience severe child maltreatment and need support from the child welfare services. However, research-supported interventions for this group are lacking. The current study piloted an intensive home-visitation intervention, Family Partner, which aims to reduce child maltreatment among at-risk paren...

The Body Appreciation Scale-2 (BAS-2) is a widely used measure of a core facet of the positive body image construct. However, extant research concerning measurement invariance of the BAS-2 across a large number of nations remains limited. Here, we utilised the Body Image in Nature (BINS) dataset – with data collected between 2020 and 2022 – to asse...

The prevalence of child sexual violence remains overwhelming, particularly among Indigenous populations, despite increased awareness. Therefore, implementing efficient initiatives is crucial in preventing and reducing sexual violence rates among these groups.This study aimed to examine the processes involved in the implementation of a sexual violen...

Dating violence during adolescence is a major public health issue: it is highly prevalent and extensive research has documented its physical and psychological consequences, yet very little has focused on its sexual consequences. The present study investigated the longitudinal associations between dating violence victimization (psychological, sexual...

Purpose: This study aimed to explore links between child maltreatment (CM) and experiences of interpersonal violence (IV) in sport among adolescent sport participants. To our knowledge, no studies have yet considered this association. This is surprising given that the literature outside of sport clearly shows that CM is related to revictimization i...

Background: The COVID-19 pandemic has been associated with increased body dissatisfaction and disordered eating behaviors in adolescents. To better understand these associations, this study tested an explanatory model in which appearance-focused social media use, internalisation of social media pressure, and mindfulness abilities mediated the relat...

This 15-year longitudinal study investigated with follow-up data how romantic patterns from ages 16 to 24 are associated with romantic involvement and turnover (ages 25-30), romantic dispositions (age 30) and romantic relationships characteristics (age 30). A sample of 255 individuals (60.8% women) identified all their romantic partners between the...

Objective This study examined the utility of a biopsychosocial model to explain both higher body mass index (BMI) and disordered eating. The study was designed to examine the predictors of higher BMI and a number of measures of disordered eating (dietary restraint, drive for muscularity, drive for thinness, binge eating, and compensatory behaviour)...

This study brings forward new evidence regarding child protection (CP) intervention for First Nations children and contributes to a longitudinal understanding of their trajectories within CP services. It raises questions regarding the persisting, unmet needs of First Nations children, families, and communities by identifying the CP factors associat...

This study assesses whether children with intellectual disability (ID) are more at risk of sexual abuse and whether they have similar consultation rates for physical and mental health disorders than children without ID. The matched-cohort design study uses administrative databases of children who had a sexual abuse report corroborated by a child pr...

Background The Canadian government’s response to the ongoing COVID-19 pandemic included the implementation of several restrictive measures since March 2020. These actions sought to decrease social contact and increase physical distancing, including that within universities. Such constraints were required to impede the transmission of the virus; how...

Malgré leur prévalence élevée, les violences sexuelles en milieu universitaire demeurent largement sous-signalées. Dans cet article, les auteures décrivent les motifs de (non-)signalement des personnes victimes, et pour celles qui ont signalé la situation, la réponse institutionnelle et les suites de la démarche. L’analyse qualitative de 197 récits...

La stigmatisation basée sur le poids est un enjeu sociétal important, puisqu’elle engendre une exclusion sociale marquée pouvant générer du stress et nuire à la santé physique et mentale des personnes qui en sont la cible, en plus de contribuer à maintenir l’obésité. La présente étude vise à explorer les prédicteurs sociodémographiques et individue...

Cadre de la recherche : Bien que tous les résidents du Québec aient été affectés par la pandémie de la COVID-19 et par les mesures sanitaires et sociales mises en place depuis le 13 mars 2020, les parents occupant un emploi rémunéré ont été particulièrement affectés par les différents stresseurs engendrés par cette crise, et ce, tant dans leur vie...

Introduction: Restrained, emotional and intuitive eating were examined in relation to each other and as correlates of participants' weight status, body image and self-esteem. In some past research, restrained and emotional eating have been associated with higher weight status and poorer mental health, while intuitive eating is more frequently link...

Background: The COVID-19 pandemic forced university staff to change their work practices. This has had an impact on their work performance and has caused various stresses. Until now, little attention has been paid to males working in this type of educational institution. In this study, we sought to determine the impact of the COVID-19 pandemic on m...

Although a range of risk factors have been identified for disordered eating and weight status, the breadth of risk factors have been rarely considered within a single, comprehensive model. The robustness of these findings across countries also remains an open question. The present study sampled 6272 participants aged 18-30 years from eight countrie...

Introduction. - The tendency to eat by paying attention and respecting the body’s hunger and satiety cues is called intuitive eating. This eating behavior has been linked to positive health and well-being outcomes. Objective. - The purpose of this study was to test a global model linking intuitive eating with self-esteem, body esteem, media influe...

Background Emotion regulation has been identified as an explanatory factor in the association between interpersonal childhood adversity and post-traumatic stress symptoms (PTSS). However, most studies focused on adults or older adolescents, neglecting youth from the community, especially gender and sexually diverse (GSD) adolescents, who have a hig...

Sexting has become part of the repertoire of adolescents’ sexual behaviors, especially among those who identify as gender and sexually diverse.
