Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Potential participants are being directed to an online survey, via a URL received in an online advertisment. The survey was designed specificaly for this study and takes approximately 10 minutes to complete.

The intervention involves reading a vignette of a hypothetical patient with a diagnosis of PTSD, who has tried several pharmacological and psychotherapeutic treatments that have failed to ameliorate their symptoms. The patient is seeking advice about participating in a Phase-III clinical trial assessing a novel pharmacotherapy treatment. The vignettes are identical except for the descriptions of the treatments. 1) Experimental group: “Methylenedioxymethamphetamine (MDMA)-assisted psychotherapy for the treatment of PTSD, as part of a phase 3 clinical trial. MDMA is commonly known as the active chemical from the party drug ‘ecstasy’”; 2) Control group: “JB-4801-assisted psychotherapy for the treatment of PTSD, as part of a phase 3 clinical trial. JB-4801 is a new drug being developed by the University”. Both vignettes stated “preliminary studies have suggested this treatment has worked for a high proportion of people with PTSD and has very low chance for negative side-effects”.

Once participants complete the questions on the page containing the vignette and progress through the survey, they can no longer read the vignette. They are able to complete the survey using any device that can connect to the internet, at any time within the data collection period. There is no time limit to complete the survey, so long as it falls within this period. They require no direct contact with study personnel. The vignettes were designed by three mental health professionals, working within psychiatry, psychology and mental health research.

Behaviour
Comparator / control treatment
The control intervention is the vignette description of a fabricated pharmcotherapy for the treatment of PTSD: "JB-4801-assisted psychotherapy". A fabricated compound ensures participants have no prior beliefs about the described treatment.

Summary
Brief summary
We aim to evaluate the attitudes of mental health professionals towards MDMA-therapy trials by a comparison of attitudes to a neutrally-labelled pharmacotherapy, using a double-blind, randomised controlled vignette study design.

We hypothesise that mental health professionals will have the following differences in attitudes towards MDMA-therapy, when compared a neutrally-labelled pharmacotherapy: 1) higher concerns for safety; 2) Lower predicted efficacy; 3) stronger objections to participation and/or lower levels of recommending participation.

By assessing professional attitudes towards MDMA-therapy for PTSD using an experimental study, we can understand if there are any biases that may be inhibiting conducting research in this area, or inhibiting the uptake of this potential new treatment by clinicians.
