FAQ: Do you provide diagnostic assessment via Skype? How does

this process work?

Thank-you for you email and comments re: my blog and inquiry re:

assessments due to a lack of services in your country.. I do provide

diagnostic assessments for women, men and teens from a variety of

countries via Skype or other means. I closely follow world expert's

procedures which are briefly as follows:

Two 2 hour appointments OR whatever combination (around 4

hours), which is spend on:

1. An interview to discuss family history, developmental history,

childhood and teen life, why you believe you may have Asperger


2. Completion of 1 formal assessment together

3. A review of a 3-4 page autobiographical description of yourself,

your experiences from your earliest memories till around age 21. This

is usually sent to me via e-mail before our first appointment.

4. The results of the assessment are discussed and if a diagnosis is

made, time is also spend on "now what?" and future

recommendations, support, are discussed in terms of social,

emotional, career, family, resources and so on.

I am available to do this in person at my clinic or via Skype. You will

be provided with a diagnostic letter, if at that point you meet the

criteria for the female or male profile of Asperger Syndrome. Please

contact me at for more informatior

or to book an appointment.

Marshall is the author of Aspiengirl. AspienWoman, Aspien Powers, and  Aspien Boy. Her works centers around functioning labels, specifically Aspergers Syndrome. 

Mashall is transphobic and also centers her work around "rapid onset gender dysphoria." She says her work is not transphobic just because she says its not.

Tania A. Marshall,  should be ashamed of herself for threatening others in our community. We do not support her as a psychologist. Your actions have proven that you do not understand the ethics and boundaries it requires to be a therapist. Agony Autie and others deserve better. Your transphobia is disrespectful and discriminatory. It's such a sad thing, especially because a lot of people use to look up to you. The ableism and transphobia needs to end! Targeting people, threatening them, slandering them, etc. are not healthy ways of advocating. 

Evidence here has proven that you are not trustworthy. 

If anyone would like to report Tania to the Australian Health Practitioner Regulation Agency, please do so here: 


The Australian Health Practitioner Regulation Agency is finally going to launch an official investigation into her unethical practices.
