Investigating the relationship between LMX, safety climate and the components of safety performance in a high accident environment

Abstract

This thesis presents two distinct, but linked, studies. Study 1 contrasted interactive [group] brainstorming against its nominal [individual] counterpart. Previous research has pointed to the productivity advantages of nominal brainstorming in terms of idea production rate [ideation], leading theorists to predict 'the end of interactive brainstorming'. Yet interactive brainstorming has remained the most popular means of ideation within organizations. Central to this research is the thesis that previous studies (a) failed to follow the instructions of the concept originator, Osborn (1953) and (b) used samples and conditions that were not representative of the organizations using brainstorming. Using a total of 10 groups sourced from a UK construction company, participants were asked to brainstorm ideas to improve organizational safety performance. Data produced indicated an equal average number of ideas generated, 30 for interactive, 30.2 for nominal, and an equal number of themes generated, 6.6 for interactive, 6.6 for nominal. Along with ideas and themes, post session group cohesion and process satisfaction levels were measured. Results indicated significantly higher levels of cohesion (t (73.75)=2.35, P
