The purpose of this study was to develop and validate an instrument to measure dimensions of the concept of a good death held by Taiwanese children. The sample consisted of 1,698 Taiwanese children, approximately 12-14 years of age. Participants completed the self-administered Good Death Concept Scale (GDCS), which consists of 30 statements describing potentially important contributors to a good death that had been identified in the relevant literature. Findings indicated that the GDCS is reliable and valid, as evidenced by the acceptable reliability, the consistent item-total correlations, the successful confirmatory factor analysis modeling, and the significant associations between the scale measuring concepts of a good death and 2 standardized scales (the Multidimensional Fear of Death Scale and the Death Attitude Profile-Revised). The results of this study suggest that GDCS measures 8 distinct domains, each reflecting a different aspect of good death: physical/biological, psychological, social, cognitive, altruistic, spiritual, affective, and rational.
