Weidman, J; Dickerson, D E and Koebel, C T (2015) Intervention to improve purchasing decision-maker perceptions of ventilated tools. Journal of Construction Engineering and Management, 141(6): 04015007, ISSN 0733-9364
Abstract
A theory-based intervention strategy to improve purchasing decision-maker perceptions of ventilated tools was developed, implemented, and tested. The intervention was designed to target key constructs of the prevention through design adoption readiness model (PtD ARM), a previously published conceptual model. A Web-based intervention was developed that included information about the health effects of construction dust, a testimonial by a firm owner, and a video demonstrating side-by-side use of both ventilated and nonventilated tools, which provided visual evidence of dust generation and productivity performance. In a pretest/posttest with a control group and an experimental design, purchasing decision makers (n=49) were contacted by telephone. A validated survey instrument was used to collect perception data and open-ended responses regarding barrier information. Gain score t-test analysis found significant improvements in perceived ease of use, health knowledge, and perceived risk in the intervention group. Open-ended results identified barriers to the use of ventilated tools. The intervention methods presented in this paper can be used by future researchers and occupational safety and health practitioners to improve the use of safety innovations.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
