Effects of video self-modeling on eliminating public undressing by elementary-aged students with developmental disabilities during urination

This study investigated the effectiveness of video self-modeling (VSM) for eliminating the public undressing of two elementary-aged students with developmental disabilities during urination. A multiple-probe design across participants revealed that the degree of exposed body parts decreased immediately after introduction of VSM. However, exposure of buttocks was not eliminated for one student until a component of hero modeling was added to the VSM. The mechanism of eliminating public undressing by use of VSM and video self and hero modeling is discussed within a framework of motivating operation.
