رساله لاتین دکترا ۲۰۱۸ “استرس های بعد از حادثه” در ۱۸۴ صفحه

Though shown effective, PTSD treatment is challenging, making motivation during
therapy the third task for a virtual agent for PTSD [68]. In this thesis, the stance
is taken that a virtual agent enhances motivation by adapting motivational feedback
to the current situation. Drop-out rates for PTSD are high even in regular therapy,
showing that therapy is difficult to complete [80]. One observation often made by
practicing therapists is that symptoms might get worse before they get better, which
can be very demotivating [81]. However, symptom progression differs per person,
and it is important to take these differences in into account. Work in the area of
recommendation systems shows that personalized feedback is important [82]. A
motivational system should therefore also reflect on the current situation during
therapy. Progress models based on questionnaires are one situational measure a
virtual agent can use to provide personalized motivation. This thesis hypothesizes
that a virtual agent can enhance trust in the therapy and motivation to continue; it
can do this by analyzing the current progress and trust of a patient in a good outcome
and adapting motivational feedback to this situation. This leads to hypothesis

How should a virtual agent
present psychoeducation?
Influence of verbal and
textual presentation on
adherence.
With the rise of autonomous e-mental health applications, virtual agents can
play a major role in improving trustworthiness, therapy outcome and adherence.
In these applications, it is important that patients adhere in the sense
that they perform the tasks, but also that they adhere to the specific recommendations
on how to do them well. One important construct in improving
adherence is psychoeducation, information on the why and how of therapeutic
interventions. In an e-mental health context, this can be delivered in
two different ways: verbally by a (virtual) embodied conversational agent or
just via text on the screen. The aim of this research is to study which presentation
mode is preferable for improving adherence.
