(2016): Usability and acceptability assessment of an empathic virtual agent to prevent major depression. In: Expert Systems: International Journal of Knowledge Engineering and Neural Networks 33 (4), S. 297-312. DOI: 10.1111/exsy.12151
DOI: https://doi.org/10.1111/exsy.12151 Abstract: In Human–Computer Interaction, the adaptation of the content and the way of how this content is communicated to the users in interactive sessions is a critical issue to promote the acceptability and usability of any computational system. We present a user‐adapted interactive platform to identify and provide an early intervention for symptoms of depression and suicide. In particular, we describe the work performed to assess users’ system acceptability and usability. An empathic Virtual Agent is the main interface with the user, and it has been designed to generate the appropriate dialogues and emotions during the interactions according to the detected user’s specific needs. This personalization is based on a dynamic user model nurtured with clinical, demographical and behavioural information. The evaluation was performed with 60 participants from the university community. The obtained results were promising, allowing the execution of a further clinical trial. The system’s usability score was 75.7%, and the score of the user‐adapted content and the emotional responses of the Virtual Agent was 70.9%.

(2014): Akzeptanz Smartphone-gestützter Rehabilitationsnachsorge bei depressiven Patienten. In: Verhaltenstherapie und Verhaltensmedizin 35 (4), S. 316-333
Abstract: Überprüft wird die Akzeptanz des smartphone-gestützten, kognitiv-behavioralen Reha-Nachsorgeprogramms eATROS für Patienten mit depressiven Störungen. 81 Patienten wurden zu einer Schulung in eATROS eingeladen. Sie erhielten danach und nach der poststationären Intervention einen Fragebogen, der sich an der UTAUT (Unified Theory of Acceptance and Use of Technology) von Venkatesh, Morris, Davis & Davis (2003) orientiert. 50 (62%) der eingeladenen Patienten nahmen die Nachsorge mit eATROS auf. Alle 50 schlossen die Behandlung ab. Wahrgenommene Nützlichkeit und Benutzerfreundlichkeit wurden vor und nach der Intervention als gut eingestuft. Besonders positiv eingeschätzt wurden die smartphone-unterstützten Features "Tagesstrukturierung" und "wöchentliches Selbstmonitoring" und "Möglichkeit zu SMS- und Telefonkontakt mit dem TeleCoach in der Klinik". Hinsichtlich seiner Akzeptanz erfüllt eATROS somit die Anforderungen an ein neues Medium zum therapeutischen Einsatz in der ambulanten Nachsorge.

(2014): Frustration and disappointment. In: Journal of Child Psychotherapy 40 (1), S. 36-57. DOI: 10.1080/0075417X.2014.883136
DOI: https://doi.org/10.1080/0075417X.2014.883136 Abstract: The paper describes research on children’s responses to failures of gratification. Although this has always been an important area of consideration in psychoanalytic thinking, arguments are put forward for the child’s actual feelings of disappointment being significant in ways that have yet to be fully realised theoretically and clinically within Kleinian object relations. Since Freud first used the term ‘frustration’, it has been applied in psychoanalysis as a means by which to describe in an undifferentiated way all those responses to failures of gratification that have an aggressive content. It will be argued that, in a context of the historical shift in thinking from drive to relational models, there is now perhaps scope to posit the existence instead of two discrete object relational positions towards such failures of aim—that frustrated responses can be differentiated in important structural and developmental ways from disappointed ones, by suggesting that the for mer are schizoid, whilst the latter are depressive in quality. To try and begin to test the hypothesis that there might be an object relational distinction between feelings of frustration and feelings of disappointment, selected process notes from two training cases became the subject of a combined piece of clinical and theoretical research. I will outline how this research was undertaken and present the findings that arose from the clinical part of it. With the use of a content analysis, a method for gathering interesting quantitative data about the children’s various responses to the failures of gratification was arrived at.
