Design outcomes

Primary

Measure	Time frame
Evaluation of feasibility, usability, treatment satisfaction and acceptance Evaluation: Feasibility of the sensor system and data transfer will be measured by self-designed questions about the respective subject. After exposer and response prevention (ERP) sessions during the treatment, the attending therapists will answer the questions. After self-managed ERP sessions, the parents of the young children (4–8 years) or the older (9–12 years) children themselves will answer the questions. The feasibility of the therapy manual created for the study will be measured using specific questionnaires, which will be answered by the therapists after each session (Manual Rating Form, Crawley et al., 2013) and once at the end of the sessions (Summary Therapist Feedback Form, Crawley et al., 2013). Usability of the app, the robot and the sensors will be evaluated by the children (with the help of their parents) in the middle (t1) and at the end of the treatment (t2) using the System Usability Scale (Bangor et al., 2008) A questionnaire regarding treatment satisfaction (Client Satisfaction Questionnaire, Attkisson & Rebecca, 1982) will be answered by the childern and their caregivers after the treatment phase (t1). Acceptance will be assessed using a self-designed evaluation questionnaire (children >9 years) and interview (children <9 years). This will be applied twice, once after the treatment (t1) and once after the aftercare phase (t2).	—
