Recent research has established the potential for virtual characters to act as virtual standardized patients VP for the assessment and training of novice clinicians. We hypothesize that the responses of a VP simulating Post Traumatic Stress Disorder (PTSD) in an adolescent female could elicit a number of diagnostic mental health specific questions (from novice clinicians) that are necessary for differential diagnosis of the condition. Composites were developed to reflect the relation between novice clinician questions and VP responses. The primary goal in this study was evaluative: can a VP generate responses that elicit user questions relevant for PTSD categorization? A secondary goal was to investigate the impact of psychological variables upon the resulting VP Question/Response composites and the overall believability of the system.
