CMHA National Survey - Major Depressive Disorder


Thank you for taking our online survey.  The Canadian Mental Health Association (CMHA) is looking to understand your experience living with symptoms of Major Depressive Disorder (MDD) or clinical depression after having tried two or more antidepressant medications with unresolved symptoms.  You may have heard this referred to as Treatment Resistant Depression (TRD).

There is little research about people who live with this kind of depression experience. CMHA wants to know how this type of depression impacts your life, which includes how it might affect your experience with family members as well as your experience in the workforce.

We know this year has been challenging for many due to the ongoing impact of COVID-19. If you choose to complete this survey, we ask that you reflect on your experience as a whole with MDD.  This means thinking about your day-to-day experience living with MDD – how you have been impacted by COVID-19 but also the experiences that you may have already had as a person living with MDD.

The survey should take no more than 10 minutes to complete.  By completing this survey, you are permitting CMHA to use the information you provide to develop resources that will support Canadians experiencing unresolved symptoms of depression after having tried two or more antidepressants.  These are resources for caregivers and employers, so they know how to best support people experiencing this type of depression.  The survey will also help us prepare for conversations with people experiencing depression that will take place across Canada.

Your participation in this survey is entirely voluntary. If you do not wish to answer any questions, please select the “Not applicable”(N/A) response option.  You can stop participating at any time by closing your browser window.  The survey is anonymous, and we cannot connect your responses back to you.  All survey findings are stored on a password protected online survey software, Survey Gizmo, which stores data in Canada and is only accessible to the researchers.  Your input will be summarized together with others who respond to the survey.

At the end of the survey, you will be asked if you want to provide your name and contact information to participate in one-on-one interview conversations happening across Canada.  This information will be collected on a separate webpage so we cannot connect your responses with your identity.  By participating in the interview process, you will allow the CMHA to get a deeper understanding of your experience with symptoms of unresolved depression.

If you experience any technical issues while completing the survey, or are in need of assistance for accessibility of the survey, you can reach out to Elizabeth, Research Coordinator, at
