The viewing of videos is a much-studied intervention to teach self-help, social, and vocational skills. Many of the studies to date looked at video modeling using televisions, computers, and other large screens. This study looked at the use of video modeling on portable handheld devices to teach hand washing to three adolescent students with an autism spectrum disorder. Three students participated in this 4-week study conducted by occupational therapists. Baseline data were obtained for the first student for 1 week, the second for 2 weeks, and the third for 3 weeks; videos were introduced when the participants each finished the baseline phase. Given the cognitive and motor needs of the participants, the occupational therapist set the player so that the participants only had to press the play button to start the video playing. The participants were able to hold the players and view at distances that were most appropriate for their individual needs and preferences. The results suggest that video modeling on a handheld device improves the acquisition of self-help skills.
观看视频是一种经过大量研究的用于教授自助、社交和职业技能的干预措施。迄今为止，许多研究关注的是使用电视、电脑和其他大屏幕进行视频示范。本研究考察了在便携式手持设备上使用视频示范，向三名患有自闭症谱系障碍的青少年学生教授洗手技能的情况。三名学生参与了由职业治疗师开展的这项为期4周的研究。第一名学生的基线数据收集了1周，第二名学生收集了2周，第三名学生收集了3周；当每位参与者完成基线阶段后引入视频。考虑到参与者的认知和运动需求，职业治疗师设置了播放器，以便参与者只需按下播放按钮就能开始播放视频。参与者能够手持播放器，并在最适合其个人需求和偏好的距离观看。结果表明，在手持设备上进行视频示范可提高自助技能的习得。
