Reliability and Validity Testing of a Short Form of the Readiness Estimate and Deployability Index Revised for Air Force Nurses

ABSTRACT Objective: The purpose of this study was to test the reliability and validity of the Readiness Estimate and Deployability Index Revised for Air Force Nurses Short Form, with a sample of 205 Air Force nurses. Participants were mostly female (70%), 36.31 ± 9.3 years of age, with 11.52 ± 7.17 years of nursing experience. Methods: With structural equation modeling, the initial model did not fit the data (χ2/df = 5.45) and was revised. Results: Revisions based on modification indices provided evidence of reliability (α coefficients of 0.70–0.94; the majority of R2 values were >0.50) and improved the fit of the model (χ2 difference, 35.54; df difference, 3.76; p < 0.05). Hypothesis testing provided evidence of construct validity. Conclusions: The 40-item Readiness Estimate and Deployability Index Revised for Air Force Nurses Short Form provides evidence of reliability and validity as a self-assessment measure of deployment preparedness.
