Help Us Learn More About Mental Illness

The Centre for Emotional Health at Macquarie University is seeking to improve the way mental illness is assessed and diagnosed in research and practice. To do this, they need to collect data on the different ways people experience a wide variety of thoughts, feelings, and behaviours to understand how these experiences tend to cluster together.

If you decide to participate in this study, you will be asked to respond to a detailed online survey that asks about your own personal experiences. After some background questions about your life, there are a series of multiple choice items with a 5-point scale to rate how true (or common) each statement was for you in the past 12 months.

When you complete the survey you can go in the running for up to $250 in pre-paid cashcards as compensation for your time, or donate these funds to a mental health charity. There are four versions of the survey that vary in length: The full version of the survey includes very wide coverage of human experience (718 items in total) and will take about 2 hours to complete. The shorter versions cover a narrower range of experiences and will take about 1 hour (388 items) 30 minutes (220 items), or 15 minutes (108 items) to complete. Your responses will be completely anonymous and confidential.

This study has been approved by the Macquarie University Human Research Ethics Committee (Project ID 6715). 

Note that this survey includes questions relating to trauma and suicidality, which may be distressing to answer. We include resources for seeking support if you feel distressed throughout the survey, and for connecting with mental health services.
