Development of the short version of the Japanese Patient Dignity Scale

Abstract

This study aimed to develop a short version of the Japanese Patient Dignity Measurement Scale（J-PDS）that measures the dignity of hospitalized patients and examine its reliability and validity. We conducted a survey using a modified version of the J-PDS, which consisted of 21 item with 5 factors for expectation regarding dignity and 21 items with 3 factors for Satisfaction with dignity. Responses were obtained from 378 hospitalized patients in 20 hospitals across Japan（response rate: 48.0％, valid rate: 100％）. After confirming the consistency between the revised and the original versions, we narrowed down the items while increasing of factor loading with exploratory factor analysis. Based on the results, we obtained a short version consisting of 12 items with 3 factors, for both expectation regarding dignity and satisfaction with dignity. Cronbach’s α coefficients were 0.89 for expectation and 0.90 for satisfaction. Regarding model fitness, the GFIs were somewhat insufficient, being 0.826 and 0.898 respectively. On the other hand, weak but significant correlation was found between Rosenberg’s Self-esteem Scale and some factors of expectation and satisfaction. We confirmed that the J-PDS short version has some amount of reliability and validity.
