Title: A Video-Based Intervention to Improve Belt Fit Open Access Deposited

Attribute Value
  • To develop the short, video-based intervention, an inter-disciplinary team of experts were consulted, including automotive safety experts, injury biomechanics researchers, behavior psychologists, communication, and video production specialists. Multiple revisions of the script for the video-based intervention were undertaken and reviewed by the experts. A pilot evaluation was conducted to assess terminology for the anatomical reference of the belt position, and to evaluate the video tutorial script and proposed graphics. A convenience sample of twenty-four community participants provided feedback that was incorporated into the video script. The final video was 100 seconds in duration.
  • This study evaluated the performance of a video-based intervention for improving the belt fit obtained by drivers. Previous laboratory studies have demonstrated that some drivers position their seat belts suboptimally. Specifically, the lap portion of the belt may be higher and farther forward relative to the pelvis than best practice, and the shoulder portion of the belt may be outboard or inboard of mid-shoulder. A video was developed to present the most important aspects of belt fit best practices, with emphasis on the lap belt. The video demonstrated how a seat belt should be routed with respect to an individual’s anatomy to ensure a proper fit. The three key belt fit concepts conveyed in the video were: 1) Lap belt low on hips, touching the thighs. 2) Shoulder belt crossing middle of collarbone. 3) Belt snug, as close to bones as possible. Additional context about the ability to achieve to good belt fit, such as opening a heavy coat or adjusting the height adjusters on the B-pillar behind the windows, were also presented.
