| dc.description.abstract | The accuracy and similarity of team members' perceptions regarding the
interdependencies of their task as well as the criticality of teamwork behaviors is
essential to team performance. Unfortunately, these perceptions are not always accurate
or similar, which has led to calls for research evaluating the effectiveness of
interventions aimed at improving these perceptions. The present study evaluated the
accuracy and similarity of crew members' perceptions of task interdependence and
teamwork in the U.S. railroad industry. Specifically, this study assessed (1) the effect of
Crew Resource Management (CRM) training on the accuracy and similarity of
locomotive and maintenance of way (MOW) crew members' perceptions and (2), the
extent to which the accuracy and similarity of those perceptions are retained 2-years
after training.
The overall results of the present study suggests that CRM training is effective in
increasing the accuracy and similarity of crew members' perceptions of team-relatedness
(amount of task interdependence) and perceptions regarding the importance of teamwork. However, the effectiveness is often dependent on the metric used (i.e.,
accuracy vs. similarity), and the specific characteristics of the crew members (i.e.,
locomotive vs. MOW, higher vs. lower interpositional experience). Furthermore, the
results suggest that training did not increase the accuracy or similarity of crew members' perceptions of team workflow pattern (form of task interdependence). Lastly, a small
sample size and low power precluded the running of quantitative statistical analysis
assessing the long-term retention of the accuracy and similarity of participants' perceptions of task interdependence or teamwork. However, for the sake of
completeness, the means, standard deviations, and effect sizes are presented in the
