A Randomized Intervention in Collision Repair Shops

描述(申请人提供)：拟议研究的目的是评估旨在减少小型汽车碰撞修理店工人暴露于各种危险的随机干预措施(标准行业分类代码7532)的有效性。这项研究的主要假设是，在业主和工人实施全面干预后，与最低限度的干预相比，环境和行政控制以及个人防护装备的可用性和使用率将更高，物理和化学危害的暴露将更低。拟议的研究利用业主和工人对车间环境的审计，制定工人/业主的健康和安全目标和行动计划，以及定期评估实现这些目标的进展情况。业界代表和社区合作伙伴将提供技术支持，并在研究咨询委员会任职。将使用两组随机对照试验来测试干预效果。每组随机分配50家商店。干预地图将作为规划模型，社会认知理论将作为行为模型。研究结果将是(1)基线和两个跟踪期之间车间危险评分的变化；(2)业主和工人关于车间安全和危险识别的知识和信念的变化；以及(3)包括过程评估、访谈和焦点小组在内的定性措施。商店将在基线(T1)、9个月(T2)和18个月(T3)进行评估。在第二次评估(T2)后，对照商店将被登记为干预商店。公共卫生意义：这项建议解决了服务不足的商业机构的工人和业主的大型社区的需求。需要新的方法来接触到小企业的所有者和工人社区。这些方法需要考虑到有限的财政资源、地理上分散的工作地点、业主和工人之间的广泛知识以及特定地点健康和安全计划的多样性。这里提出的方法使受影响的社区能够积极参与识别问题和解决方案，参与健康和安全计划的传播，并通过行业协会和基于社区的技术培训计划确保新计划可以长期持续下去。

DESCRIPTION (provided by applicant): The purpose of the proposed research is to evaluate the effectiveness of a randomized intervention designed to reduce exposure to diverse hazards among workers in small auto collision repair shops (Standard Industrial Classification Code 7532). The primary hypothesis of this study is that the availability and use of environmental and administrative controls and personal protective equipment will be greater, and exposure to physical and chemical hazards will be lower, after a comprehensive intervention implemented by owners and workers compared with a minimal intervention. The proposed study utilizes owner and worker auditing of the shop environment, the development of worker/owner health and safety goals and action plans, and periodic assessment of progress towards meeting these goals. Industry representatives and community-based partners will provide technical support and serve on a study Advisory Board. A randomized controlled trial with two groups will be used to test intervention effectiveness. Fifty shops will be randomly assigned to each group. Intervention mapping will serve as the planning model and Social Cognitive Theory will serve as the behavioral model. Study outcomes will be (1) A change in shop hazard score between baseline and two follow-up periods; (2) Changes in owner and worker knowledge and beliefs with regard to shop safety and hazard recognition; and (3) Qualitative measures including process evaluation, interviews, and focus groups. Shops will be evaluated at baseline (t1), nine months (t2), and 18 months (t3). After their second evaluation (t2), control shops will be enrolled as intervention shops. Public Health Significance: This proposal addresses the needs of a large community of workers and owners of underserved business establishments. New methods are needed to reach the community of owners and workers in small business establishments. These methods need to account for limited financial resources, geographically dispersed work sites, the wide range of knowledge among owners and workers, and the variability of site-specific health and safety programs. The approach proposed here allows for the affected community to be actively engaged in identifying problems and solutions, take part in the dissemination of health and safety programs, and assure new programs may be sustained on a long-term basis through trade associations, and community-based technical training programs.
