Dr. Iris Balodis is an Assistant Professor in the Department of Psychiatry and Behavioural Neurosciences at McMaster University. Dr. Balodis’ research focuses on motivational processes influencing maladaptive decision-making.

 

About The Lab:

 

Dr. Balodis is a core faculty member of the Peter Boris Centre for Addictions Research (PBCAR), a centre dedicated to addiction research.

 

Dr. Balodis’ research is focused on understanding how affective processes influence higher order cognitive functions, such as decision-making. Why is there so often a disconnect between our desires and our actions? For example, many people express a genuine desire to lose weight, yet continue to choose to eat calorie-rich foods. In fact, many common societal problems can be attributed to this disconnect: obesity, money mismanagement, and substance abuse all represent cases in which an immediate short-term reward (e.g. a piece of a cake, a 50” flat-screen TV, another beer…) is chosen over a future greater reward (a svelte figure, savings, health). Little is known about how affective processes integrate into core executive functions; this research not only is important for understanding how humans make decisions, but also has significant implications for understanding many psychiatric conditions characterized by poor decision-making. Towards the goal of better understanding these processes, Dr. Balodis’ lab applies functional Magnetic Resonance Imaging (fMRI), psychophysiological, behavioural, and other approaches to various populations demonstrating a range of maladaptive behaviours. These include individuals at risk for addictions, such as young binge drinkers, individuals with gambling disorder, and individuals demonstrating different eating pathologies, such as binge eating disorder.

The Peter Boris Centre for Addictions Research (PBCAR) is a Knowledge Hub for the Gambling Research Exchange of Ontario (GREO) with a specialized focus on the neurobiological mechanisms underlying gambling.
A principal goal of the PBCAR is to bridge the gap between scientific research and clinical practice; as a collaborative venture between McMaster University and St. Joseph's Healthcare Hamilton, it is ideally positioned to do so.

Aim: The main aim of the PBCAR GREO Knowledge Hub is to engage numerous stakeholders, including students, residents, clinicians, the greater Hamilton community and the broader general public accessible information on the neurobiology of gambling.

We do this through a variety of activities:

  • Lectures
    • PBCAR members deliver lectures to students, residents and other trainees on the neurobiology of gambling
  • Presentations
    • PBCAR members deliver primers on the neurobiology of gambling to clinicians, individuals with problem gambling, as well as the general public.
  • Reviews
    • PBCAR members are conducting systematic reviews in order to contextualize gambling research findings to the broader addiction research community.
  • Engagement products
  • Training of early-stage investigators
    • Hub members receive training to develop content knowledge and knowledge translation and exchange capacity.
  • Collaborations
    • PBCAR members collaborate with clinicians and community members to provide better access to the research base
      • One current community collaboration is with Alcohol Drug and Gambling Services (ADGS) of Hamilton.
        • "I Love A Good Clinical Handout!" - This project is innovative in bringing together problem gambling researchers and clinicians to highlight relevant research findings. Specifically, this collaboration aims to develop useful clinical handouts for PG counsellors with a focus on neurobiology to use with clients on themes raised by the clients themselves. Five topics have been developed for five handouts:
  • How is problem gambling like substance use disorders to the brain?
  • Why do problem gambling clients experience gambling as impulsive and pleasurable early in their gambling experiences and then compulsive and not pleasurable once the problem is fully formed?
  •  Why does substitution happen (from gambling to substances, gaming or other process addictions)?
  • Why is it hard to say 'no' to an urge?
  • Why is it difficult to find non-gambling activities pleasurable in early recovery (the pleasure scale)?

COMMUNITY COLLABORATION
Current Projects
Dr. Iris Balodis is working in collaboration with Deirdre Querney, a counselor at Alcohol, Drug and Gambling Services of Hamilton to create clinical handouts for clients with up-to-date information on the neurobiology of gambling. Deirdre Querney is a Registered Social Worker and Certified Problem Gambling Counsellor for the City of Hamilton, Public Health Services and Clinical and Preventive Services. This project is supported through the Gambling Research Exchange Ontario (GREO).
The goal of this project is to bring together problem gambling (PG) researchers and problem gambling clinicians to develop useful clinical handouts for PG counselors. The focus of the handouts is on recent research findings to use with clients based on themes raised by the clients themselves. The clinical handouts aim to translate neurobiology research in an accessible and educational format for problem gambling clients.
