Learning Objective 1: Discuss the circular relationship of theory and research.
Learning Objective 2: Review mathematical and statistical strategies used to test the Hospital Nurse Force and Fatigue Theory.
Methods: There were two primary strategies used to guide theory testing: a mathematical formula using an equation derived from physics and a statistical confirmatory factor analysis methodology. The statistical confirmatory factor analyses are represented in three phases: preparation, model testing, and reporting the results. Model testing is divided into: specification, identification, estimation, evaluation and modification. Analyses are reported with standardized regression coefficient of the items related to the latent variables and squared multiple correlations related to error terms and the model’s goodness of fit indexes. The mathematical formula used to test Hospital Nurse Force is Force = Mass x Acceleration where Nurse Force = The Essential work of Hospital Nurses, Mass = Nurse (Wellness + Professionalism + Education) and Acceleration = Hospital Bio-Political Environment.
Results: Results of the theory testing are currently in progress and not available for submission in the December 2012 abstract. Results will provide analyses of the theory domains as described in the methodology. The primary domains of the theory include: Hospital Nurse, Nurse Force, Hospital Bio-political environment, and Patient Harm.
Conclusion: Tested theories are needed to develop and advance nursing science. This theory testing was used to clarify study concepts and domains and has helped determine further clinical investigation to test interventions to measure and prevent hospital nurse fatigue and patient harm.
