Seat belt use provides significant public health benefit, however, most public awareness campaigns have generally focused on seat belt use rather than encouraging adults to improve seat belt fit with belt placement. This study provides an evaluation of a video-based intervention to improve adult belt fit assessing whether a video-based intervention can target beliefs and knowledge of seat belt placement and be perceived as relevant by the target audience.
An intervention group of 29 adults (15 women and 14 men) and a comparison group of 99 adults (41 women and 47 men) participated.
The intervention group had significantly more favorable beliefs around belt fit than the comparison group related to Health Belief Model constructs of higher self-efficacy, greater benefits, and fewer barriers. The intervention group was also significantly better at accurately drawing belt fit than the comparison group. The video intervention was described as relevant, interesting, and the intervention group favored the provision of a diverse sample of models in the intervention.
Overall, the study provides insight into relevant target beliefs for an intervention focused on belt fit and suggests that a brief video-based intervention in the style of a public service announcement may be effective in promoting positive beliefs and knowledge around belt fit. Future efforts should confirm these findings with a larger sample size spanning multiple geographic and demographic areas.
These findings can help better inform intervention initiatives to improve occupant belt fit.
系安全带对公众健康有重大益处，但大多数公众意识宣传活动通常侧重于系安全带，而不是鼓励成年人改进安全带的佩戴方式。本研究评估了一项基于视频的干预措施，以改善成人安全带的佩戴贴合度，评估基于视频的干预措施是否可以针对安全带佩戴的信念和知识，并被目标受众认为是相关的。
一个干预组由 29 名成年人（15 名女性和 14 名男性）和一个对照组 99 名成年人（41 名女性和 47 名男性）组成。
干预组在与健康信念模型相关的更高的自我效能、更大的益处和更少的障碍等方面，对安全带贴合度的信念明显优于对照组。干预组在准确绘制安全带贴合度方面也明显优于对照组。视频干预被描述为相关、有趣的，干预组倾向于在干预中提供多样化的模特样本。
总的来说，该研究深入了解了以安全带贴合度为重点的干预措施的相关目标信念，并表明，以公益广告形式的简短基于视频的干预措施可能有效促进安全带贴合度的积极信念和知识。未来的研究应在更大的样本量和跨多个地理和人口统计学领域的基础上确认这些发现。
这些发现可以帮助更好地为改善乘客安全带贴合度的干预措施提供信息。
