Comparative Study
Comparing the psychometric properties of the EQ-5D-3L and EQ-5D-5L in cancer patients in Korea.
This study was conducted to assess the redistribution properties of the EQ-5D-3L when using the EQ-5D-5L and to compare the validity, informativity, and reliability of both EQ-5D-3L and EQ-5D-5L in Korean cancer patients. ⋯ The EQ-5D-5L had greater informativity and lower rate in the ceiling effect than those values of the EQ-5D-3L. The EQ-5D-5L showed good construct validity and reasonable reliability. Therefore, considering these findings, the EQ-5D-5L may be preferable to the EQ-5D-3L.

Quality of care for long-term care (LTC) residents with dementia at the end-of-life is often evaluated using standardized instruments that were not developed for or thoroughly tested in this population. Given the importance of using appropriate instruments to evaluate the quality of care (QOC) and quality of dying (QOD) in LTC, we compared the validity and reliability of ten available instruments commonly used for these purposes. ⋯ Our comparative study of psychometric properties of instruments allows for informed selection of QOC and QOD measures for LTC residents with dementia.

The COSMIN checklist is a standardized tool for assessing the methodological quality of studies on measurement properties. It contains 9 boxes, each dealing with one measurement property, with 5-18 items per box about design aspects and statistical methods. Our aim was to develop a scoring system for the COSMIN checklist to calculate quality scores per measurement property when using the checklist in systematic reviews of measurement properties. ⋯ Based on experience in testing this scoring system on 46 articles, the COSMIN checklist with the proposed scoring system seems to be a useful tool for assessing the methodological quality of studies included in systematic reviews of measurement properties.

Neuro-QOL provides a clinically relevant and psychometrically robust health-related quality of life (HRQL) assessment tool for both adults and children with common neurological disorders. We now report the psychometric results for the adult tools. ⋯ The Neuro-QOL measurement system provides item banks and short forms that enable PRO measurement in neurological research, minimizes patient burden and can be used to create multiple instrument types minimizing standard error. The 17 adult measures include 13 calibrated item banks, 3 item pools available for calibration work by others, and 1 stand-alone scale (index). The Neuro-QOL instruments provide a "common metric" of representative concepts for use across patient groups in different studies.

We compared Japanese versions of the EORTC QLQ-C15-PAL and QLQ-C30 to assess the utility of the former survey for terminal-phase cancer patients. ⋯ We examined the validity and reliability of the Japanese version of the QLQ-C15-PAL. We found an 87% or higher chance that the QLQ-C15-PAL could explain the original QLQ-C30 score. Therefore, QLQ-C15-PAL appears to be useful for assessing the QOL of terminal-phase cancer patients.
