Charlie Rioux

My general research interests are in mental health promotion, developmental psychology, and research methodology. I conduct interdisciplinary and collaborative research on a wide variety of topics, that mostly centre around three interrelated overarching themes:

1. Examining risk and protection factors for psychopathology

I examine the interplay of environmental and individual factors as well as the mechanisms that link them to future psychopathology. I use a developmental perspective, examining factors from the prenatal period to adulthood. My research has examined a wide range of mental health problems, with more focus on substance use, depression, anxiety, and suicidal ideations and attempts. My previous and current projects have examined many individual and environmental factors related to psychopathology, such as temperament/personality, parenting, romantic relationships, peer relationships, puberty, obesity, ethnicity/race, gender, sleep, and sexual orientation.

2. Inform the development of effective targeted prevention and intervention programs

My observational research on psychopathology allows the identification of malleable risk and protection factors. As a collaborator with research teams in clinical psychology, I aim to apply findings from my observational research to early prevention and intervention programs.

3. Contributing to the accessibility and use of state-of-the-art research methods

My research in quantitative psychology aims to identify key gaps in statistical training and the literature to inform educational methodological articles that are in a language accessible to applied researchers. My main expertise is in structural equation modeling (SEM) and longitudinal analyses. My interests in research methods also include scientific communication, with ongoing projects on gendered language in research and on knowledge translation.
