Effective Intervention Strategy to Improve Worker Readiness to Adopt Ventilated Tools

Weidman, Justin / Dickerson, Deborah E. / Koebel, Charles T.

An effective theory-based intervention strategy is developed to improve worker adoption of a ventilated dust-control tool that reduces dust exposure by 95%. The Prevention through Design Adoption Readiness Model (PtD ARM) was employed to develop educational materials, hands-on training, and worksite cues-to-action. Educational materials were targeted to improve worker knowledge of the health risks associated with construction dusts. Hands-on training was developed with the objective of improving worker self-efficacy regarding the new equipment. Additionally cues-to-action were given to the workers. These cues were hard-hat stickers and $t$ -shirts with reminder slogans. In a pretest/posttest experimental design with control group ( $n = 40$ ), questionnaire data were analyzed using independent $t$ -tests of the gain-scores, and significant changes ( $p < 0.05$ ) were seen in worker self-efficacy, trust-in-technology, and overall readiness to adopt the tool. Theory-based intervention strategies were found to be effective in improving worker willingness to use ventilated tools. The most impactful intervention methods include training regarding risks to worker health, hands-on training with ventilated tools, and cues-to-action reminders to use the tools.
