Multimorbidity–having two or more coexisting chronic conditions–is highly prevalent, costly, and disabling to older adults. Questions remain regarding chronic diseases accumulation over time and whether this differs by racial and ethnic background. Answering this knowledge gap, this study identifies differences in rates of chronic disease accumulation and multimorbidity development among non-Hispanic white, non-Hispanic black, and Hispanic study participants starting in middle-age and followed up to 16 years.

We analyzed data from the Health and Retirement Study (HRS), a biennial, ongoing, publicly- available, longitudinal nationally-representative study of middle-aged and older adults in the United States. We assessed the change in chronic …

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 …
