Lingard & Rowlinson (1997). Total N not reported; participants were workers and site staff from 7 construction sites. Baseline assessments of safety performance in the categories of housekeeping, access to heights, bamboo scaffolding, and personal protective equipment were conducted for 17 weeks prior to introduction of the intervention. The intervention consisted of participative goal setting and performance feedback - goal setting meetings were conducted by the researcher and involved showing a series of slides depicting good and bad practice; giving workers feedback from the period of baseline measurement; and setting a realistic goal for improvement.
