Important Information

Due to the current situation in Nova Scotia and other parts of Canada, we would like to stress that this website is not monitored on a daily basis. For information on mental help resources and crisis interventions, please refer to health authorities in your community. You can also access helpful resources on our News page.




Predicting Risks and Outcomes of Social InTeractions (PROSIT)

PROSIT is a research study that aims to improve the mental well-being of youth. To achieve this goal, we are working with healthy youth and patients in Nova Scotia.  From our healthy participants, we wish to learn what youth can do to stay healthy, and from our patients, to learn how youth can quickly recover from  a mental disorder.

We believe that the way youth interact with their family and friends can tell us a lot about their health and well-being. Often, youth are simply asked by clinicians how they socially interact, but it can be difficult to remember every social interaction one has with their family members and friends. Therefore, we have created an app that passively captures information on the daily social  interactions of youth.

Our app can tell us how many calls youth are making, how many messages they  are sending, and how often they are using social media to interact with their family and friends. By understanding the social behaviours of youth, we can better understand how to best help youth to become and stay healthy and create programs to better support Nova Scotian youth.



Modern technology can help improve your care. Through the built-in sensors of your smartphone, clinicians can track your daily activities, such as calls, messaging and so on. This can let them know how you are doing and if you need help.


Gratitude Intervention Application


Gratitude interventions decrease depression, stress and anxiety symptoms. It also aids in coping with health-related problems and may improve psychological and physical functioning in areas where mental and biological processes are directly related (e.g., the cardiovascular system).  However, previous research in this area is limited to a few studies examining the impact of only one type of gratitude task (i.e., gratitude journaling on selected psychological and cardiovascular variables). 

Thus, we have developed a new intervention technique, the GIA app, to examine whether a gratitude intervention can effectively improve psychological and cardiovascular functioning as measured by depression, anxiety and stress symptoms, positive and negative affect, resting heart rate and HRV. 

Protecting the privacy and confidentiality of all app users is our main priority; to find out more about how the information is collected from the app and how we protect your privacy and confidentiality please click the link: GIA Privacy Policy 








Social Media Study

Social media can offer numerous potential benefits to its users. It can promote a sense of community, strengthen interpersonal connections and facilitate access to knowledge and social support networks. However, concerns have been raised about its potential harms. Research suggests that social media may be linked to poor mental well-being in adolescence. Frequent social media use has been associated with an increased likelihood of symptoms attributed to anxiety disorders and depression, ADHD and problematic drinking. To better understand this relationship, we are using a mobile-sensing app that objectively and passively records how adolescents use social media. In doing so, we will be able to assess whether social media use predicts adolescent mental well-being and determine whether associations of social media use with poor mental well-being are mediated by motives of use, cyberbullying or reduced physical activity and sleep.
