Our Multidisciplinary Approach
Mental Health Research at CHEO integrates the three pillars of our mission of high quality clinical care, ground-breaking research, and the education of the next generation of clinical scholars. A number of active research groups exist in psychiatric emergency services, eating disorders, ADHD, pediatric-mental health interface, and knowledge mobilization and outcomes management. Among the research scholars are local, provincial, national, and international leaders of research in child and youth mental health. All of the research enterprises are fully embedded in clinical practice creating the opportunity for the mental health community to be the type of learning environment expected in one of Canada’s leading pediatric teaching hospitals.
Mental Health in the Emergency Department
While 15% of children and youth live with a mental illness, only 1 in 6 receives any substantial mental health services. Emergency Departments (ED) are increasingly becoming a primary source to obtain mental health services for children and youth. Some researchers propose that this increase is due to lack of inpatient and outpatient mental health services. The range of mental health emergency services provided and the subsequent direct and indirect follow-up care after discharge from the emergency department varies with limited understanding of the factors that influence clinical decision making. The long-term goal of this research is to develop evidence-based practice and clinical guidelines for the delivery of ED mental health services for children and youth.

Heavy social media use and psychological distress among adolescents: the moderating role of sex, age, and parental support
04/07/2023
The current study is a secondary data analysis of the 2019 Ontario Student Drug Use and Health Survey (OSDUHS) (46). This representative cross-sectional school-based survey included Ontarians in grades 7–12 from English and French public and Catholic schools (n = 14,142). Two hundred sixty-three schools from 47 public and Catholic school boards participated in this survey. Ethics approval was obtained from the Research Ethics Boards of the Center for Addiction and Mental Health (CAMH; 029/2016), York University (e2014-099), and 47 public and Catholic school boards’ research review committees. Participation in the survey required active parental written consent and student assent. The survey was completed anonymously during school time.

Associations Between Type and Timing of Physical Activity and Sedentary Behavior With Mental Health in Adolescents and Young Adults
23/06/2023
Leisure-time PA was found to have a favorable association with mental health, particularly in the evenings of weekdays and afternoons of weekend days. On the other hand, leisure SB was associated with poorer mental health in most of the time segments analyzed, and nonleisure SB in the evenings was also related to worse mental health. The type and timing of PA and SB behaviors play an important role in the relationship with mental health.

Loneliness during COVID-19 and its association with eating habits and 24-hour movement behaviours in a sample of Canadian adolescents
23/06/2023
Loneliness is a recognized public health concern and has exacerbated during the COVID-19 pandemic due to the lockdowns and decreased social interactions (Ernst et al., 2022). This may have resulted in emotional distress and disordered eating in adolescents; however, no studies have examined the association between loneliness and breakfast skipping. Skipping breakfast is an unhealthy behaviour pattern that can transition from adolescence to adulthood with detrimental impacts on health (Smith et al., 2010). Many adolescents skip breakfast despite the benefits of regular breakfast consumption.

Longitudinal associations between different types of screen use and depression and anxiety symptoms in adolescents
28/04/2023
Higher screen time was longitudinally associated with higher anxiety and depression symptoms at one-year follow-up in adolescents. Time-change associations between screen usage and depressive and anxiety symptoms were observed. Also, associations differed based on sex and screen type, whereby greater increases in screen use predicted greater emotional distress. Findings from this prospective analysis suggest that screen time is an important determinant of anxiety and depressive symptoms among adolescents. Future studies are recommended to help inform programs promoting screen time reduction with a goal to enhance adolescents’ mental health.

Pediatric emergency department physicians’ perceptions of virtual mental health assessments for urgent needs
07/02/2023
While many physicians agreed that there is a potential benefit of the ED virtual care platform for urgent mental health assessments, time constraints and lack of confidence in providing satisfactory virtual mental health care with minimal mental health support limited its acceptability. These findings can inform the future implementation of mental health services using an innovative virtual ED platform.

Sociodemographic and mental health characteristics associated with changes in movement behaviours due to the COVID-19 pandemic in adolescents
02/10/2022
Ongoing efforts continue to be made to understand the potential impacts of COVID-19-related preventative public health measures. This large cross-sectional study is among the first to describe the sociodemographic and mental health characteristics of Canadian adolescents in relation to perceived changes in movement behaviours during the months immediately following introduction of lockdown measures. The survey capturing responses of students across Ontario, Quebec, and British Columbia (Canada) found that a perceived increase in screen time as a result of the pandemic was highly prevalent, with social media increase among females compared to males having the largest effect size among gender-based comparisons of movement behaviour changes.

Physician Perspectives on the Implementation of a Trauma Informed Care Initiative in the Maternity Care Setting
18/08/2022
Building on previous research, physicians were concerned about the time required to engage in conversations about trauma with patients (Flanagan et al., 2018; Purkey et al., 2018). Interestingly, while time management was a concern, physicians also acknowledged that not every case required additional time. Specifically, some physicians identified that some patients may require more time to discuss concerns while others did not feel the need to have detailed discussions about their past experiences

Cyberbullying involvement, parental support, and cannabis use among adolescents
13/08/2022
Our results showed that cyberbullying involvement in any role (i.e., cyberbullying victim only, cyberbullying perpetrator only, or cyberbullying perpetrator-victim) was associated with greater odds of cannabis use after adjusting for important covariates. Results further indicated that higher parental support was associated with lower odds of cannabis use in a dose-response fashion. Higher parental support was also associated with a lower risk of cyberbullying involvement.

Appearance satisfaction mediates the relationship between recreational screen time and depressive symptoms in adolescents
18/07/2022
Our results indicate that appearance satisfaction medi-ated the direct effect of recreational screen time on depressive symptoms, recreational screen time was sig-nificantly related to lower appearance satisfaction, which was significantly predictive of more severe depres-sive symptoms. As such, findings warrant randomized controlled trials designed to determine whether modu-lating screen time may be an efficacious strategy to reduce appearance dissatisfaction and depressive symp-toms during adolescence.

Associations between screen time and cognitive development in preschoolers
26/08/2021
Higher total screen time was unfavourably associated with working memory in preschoolers, while adherence to global and national screen time recommendations appeared to be a protective factor. Therefore, these findings provide further evidence for the importance of pediatricians and other health professionals discussing screen time recommendations with families, given these individuals are seen as a credible source for parents (32). Screen time was unrelated to expressive vocabulary in our sample.

Coping in adolescents: A mediator between stress and disordered eating
16/06/2021
Overall, the findings from this study are among the first to demonstrate significant mediation relationships between stress (both negative life events and perceived stress) and ED symptomatology for emotion-oriented coping in both male and female adolescents. These findings suggest that using emotion-oriented coping in response to real or perceived stress increases the risk for ED symptomatology across all adolescents. These findings suggest that intervention or prevention efforts aimed at teaching adolescents how to tackle or cope with a problem by aiming to address the stressor itself (i.e. task-oriented coping) versus trying to escape the emotion that accompanies it may have a protective effect against emerging ED symptomatology, and likely full-blown eating disorders in the face of stress during a vulnerable developmental period.
