Research Projects

  1. A Primary Care Mental Health Pathway for Children and Youth: A Mental Health Services Quality Improvement Initiative in Ontario


  2. Parenting during the COVID-19 pandemic: The sociodemographic and mental health factors associated with maternal caregiver strain


    Introduction: The COVID-19 pandemic has introduced new stressors for parents (“caregivers”) that may affect their own and their child’s mental health (MH). We explored self-reported levels of caregiver strain (parents’ perceived ability to meet parenting demands), and the MH and sociodemographic factors of caregivers to identify predictors of strain that can be used to guide MH service delivery for families.

  3. What’s the harm in asking? A systematic review and meta-analysis on the risks of asking about suicide-related behaviors and self-harm with quality appraisal


    Unfortunately, misperceptions of harm remain which can compromise clinical care, research, and public health surveillance efforts. Our objective was to evaluate the empirical evidence on whether and how asking about suicide related behaviors (SRB), such as suicidal ideation and suicide attempts, and non-suicidal self-injury (NSSI) results in harmful outcomes.

  4. The HEADS-ED: Evaluating the Clinical Use of a Brief, Action-Oriented, Pediatric Mental Health Screening Tool


    Results support the HEADS-ED's use by PED physicians to help guide the assessment and referral process and for discussing the clinical needs of patients among health care providers using a common action-oriented language.
