Towards an Affective Interface for Assessment of Psychological Distress

摘要

Even with the rise in use of TeleMedicine for health care and mental health, research suggests that clinicians may have difficulty reading nonverbal cues in computer-mediated situations. However, the recent progress in tracking affective markers (i.e., displays of emotional expressions on face and in voice) has opened the door to new clinical applications that might help health care providers better read nonverbal behaviors when employing TeleMedicine. For example, an interface that automatically quantified affective markers could assist clinicians in their assessment of and treatment for psychological distress (i.e., symptoms of depression and Post-traumatic Stress Disorder (PTSD)). To move towards this prospect, we will show that clinicians' judgments of these nonverbal affective markers (e.g., smile, frown, eye contact, tense voice) could be informed by such technology. The results of our evaluation suggest that clinicians' ratings of nonverbal affective markers are less predictive of psychological distress than automatically quantified affective markers. Because such quantifications are more strongly associated with psychological distress than clinician ratings of these same nonverbal behaviors, an affective interface providing quantifications of nonverbal affective markers could potentially improve assessment of psychological distress.
