Using Motion Tracking to Measure Avoidance in Children and Adults: Psychometric Properties, Associations With Clinical Characteristics, and Treatment-Related Change

Avoidance is implicated in many areas of psychopathology, particularly anxiety and its disorders. Accurate, reliable, valid, and objective measurement of avoidance behavior poses methodological challenges. Two key technological advances, increased computing power and the advent of motion-tracking technology, offer novel solutions to these challenges. We describe a series of three studies using a novel motion-tracking system to measure avoidance...
