Abstract
Purpose
This study aimed to systematically identify, appraise, and summarize the psychometric properties of instruments used to measure the quality of dying and death in Asian countries.
Methods
The Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) was closely followed. The literature was searched using the following keywords and their synonyms: “death and dying,” “measurement,” and “Asian country” in CINAHL, PubMed, PsycInfo, Web of Science, and Cochrane Library from inception to April 2021. Two reviewers independently screened titles and abstracts and reviewed the full text. Two other reviewers independently assessed the quality of the identified studies in three steps: methodological quality evaluation, good measurement properties evaluation, and quality of evidence evaluation.
Results
This review retrieved 37,195 studies, of which seven were finally included. Four instruments that assessed the quality of dying and death in Asian countries were identified: the Good Death Inventory (GDI), the Good Death Scale (GDS), and two versions of the Quality of Dying and Death (QODD) Questionnaires. All included studies failed to evaluate all the recommended psychometric properties, and none of the instruments provided strong evidence of their quality among Asian populations. Overall, the grade of evidence quality for the GDI was moderate, the highest among all identified instruments.
Conclusion
The GDI is by far the most reliable instrument for assessing the quality of dying and death in Asian populations. A lack of validation studies in Asian and Western cultures, however, warrants caution when drawing conclusions from the GDI.
