Zohar and Luria’s (2005) safety climate (SC) scale, measuring organization- and group- level SC each with 16 items, is widely used in research and practice. To improve the utility of the SC scale, we shortened the original full-length SC scales. Item response theory (IRT) analysis was conducted using a sample of 29,179 frontline workers from various industries. Based on graded response models, we shortened the original scales in two ways: (1) selecting items with above-average discriminating ability (i.e. offering more than 6.25% of the original total scale information), resulting in 8-item organization-level and 11-item group-level SC scales; and (2) selecting …

The Role Of Simulation In Mixed-Methods Research: A Framework & Application To Patient Safety, Jeanne-Marie Guise, Matthew Hansen, William E. Lambert, Kerth O'Brien

Psychology Faculty Publications and Presentations

Background: Research in patient safety is an important area of health services research and is a national priority. It is challenging to investigate rare occurrences, explore potential causes, and account for the complex, dynamic context of healthcare - yet all are required in patient safety research. Simulation technologies have become widely accepted as education and clinical tools, but have yet to become a standard tool for research.

Methods: We developed a framework for research that integrates accepted patient safety models with mixed- methods research approaches and describe the performance of the framework in a working example of a large …
