Abstract
Purpose: The purpose of this study were to develop and validate the Discharge Planning-Process Evaluation Measurement (DCP-PEM).
Methods: The subjects were 69 nurses in “A” hospital wards and 174 nurses in “B” hospital wards. We used a self-report questionnaire including subject characteristics, DCP-PEM, Visual Analogue Scale (VAS) and Nursing Autonomy Scale (NAS). We examined the reliability and validity of the DCP-PEM by item analysis technique, corrected item-total correlation, Cronbach's α coefficient, G-P analysis, Pearson's correlation coefficients in the DCP-PEM with VAS and NAS, and known-groups technique. For validation of the DCP-PEM, we comparatively studied the change in the DCP-PEM score before and after an intervention using a quality improvement tool with a control group, and also examined the sensitivity.
Results: The following results were obtained: 1) Skewness and kurtosis in item, factor and total scores of the DCP-PEM were within ±1.0, and correlation coefficient of CITC in all items was very high over 0.471. Cronbach's α coefficient in item, factor and total scores ranged from 0.76 to 0.96. There were significant differences in all items by G-P analysis. Since factor and total scores of DCP-PEM, VAS and NAS were significantly correlated each other in “A” hospital, the concurrent validity was established. By the known-groups technique, factor and total scores in “A” hospital were significantly higher than those in “B” hospital, suggesting that the construct validity was established. 2) The DCP-PEM scores in some items of the intervention group were higher than those in the control group. The DCP-PEM was validated due to a high sensitivity.
Conclusion: The results suggest that development of the quantified DCP-PEM enables a comprehensive evaluation of the DCP and contributes to greater impacts of the DCP practice.
