Computer-based social anxiety regulation in virtual reality exposure therapy. Promotor: Prof.dr. M.A. Neerincx (EWI).

Social anxiety disorder (SAD) is one of the most often occurring types of mental disorders. Cognitive behaviour therapy (CBT) is the most thoroughly studied nonpharmacologic approach to the treatment of SAD patients. Virtual Reality Exposure Therapy (VRET) has been suggested as an alternative to overcome many shortcomings of in vivo exposure in CBT.  

This thesis proposes a blueprint of a home-based VRET system which could evoke the required anxiety in patients with substantial level of presence. The blueprint recognizes three essential system abilities to: 1) measure the patient’s anxiety level automatically; 2) elicit and control the anxiety evoking stimuli within the social scene; and 3) introduce autonomous anxiety regulation. These abilities provide in due course the possibility to build an effective home-based VRET system.


In September 2017, the Board for Doctorates of TU Delft decided to postpone the thesis defence of Mr D. Hartanto due to signs of questionable behaviour. Therefore, The Board for Doctorates found it necessary to have an extra screening of his doctoral dissertation. The reassessment has shown that Mr Hartanto's thesis is sufficiently solid scientifically. Given this fact, the Board for Doctorates has, after serious and thoughtful consideration, decided to allow Mr Hartanto to defend his dissertation and propositions in public on 15 July 2019
