Participate in an anti-anxiety research study

Measuring the effects of medications on behaviour

Do you worry a lot? Are you being prescribed an anti-anxiety medication? Or would you like an assessment of your anxiety?

We are investigating the effect of anti-anxiety medication on reducing anxiety symptoms, as well as breathing perception and its relationship to anxiety. This research will help us understand how the treatment works, and how we can best use it in the future to help people cope with their anxiety.

Are you eligible?

  • Aged between 18 and 45 years.
  • Have a new prescription for an anti-anxiety medication that is a selective serotonin reuptake inhibitor (SSRI), such as sertraline or citalopram.
  • Have full colour vision.
  • Not suffering from any chronic medical disorders, including any current or past history of a severe brain injury or breathing disorder e.g. severe asthma, chronic obstructive pulmonary disease etc.
  • No past or current diagnoses of schizophrenia, bipolar disorder, drug addiction or psychosis.
  • Not pregnant or breastfeeding.

What does the study involve?

1 × eligibility and introduction session (30mins – either by phone or in person).

2 × assessments (3 hours each) – before and after taking your anti-anxiety medication for 6 weeks.

You will be reimbursed for your time spent in the assessments ($150 total).


Please contact Dr Olivia Harrison for further information, or see our participant information sheet.
