  • Departures from health universalism? A value set of AP-7D in Japan as an attempt to develop a “culture-specific” preference-based measure

    Open Access•Takeru Shiroiwa, Yasuhiro Morii et al.•ARTICLE•Social Science & Medicine•2026

    Health universalists believe that preference-based measure (PBM) instruments can be applied across cultures because they share similar health concepts in the world. This is the prevailing policy in PBM development. However, health pluralists refute this idea, as they argue that the concept and components of health differ depending on culture. To incorporate the pluralist view, we developed the Asian Preference-Based Measure-7 Dimensions (AP-7D), …

  • Japanese value set for the EORTC QLU-C10D

    Open Access•Takeru Shiroiwa, Madeleine King et al.•ARTICLE•Quality of Life Research•2024

    The Japan-specific QLU-C10D value set is suitable for evaluating the cost and utility of oncology treatments for Japanese health technology assessment and decision-making

  • Valuation survey for SF-6Dv2 in Japan based on the international protocol

    Open Access•Takeru Shiroiwa, Yosuke Yamamoto et al.•ARTICLE•Quality of Life Research•2024

    We obtained a value set for Japan (model 5). With the development of this value set, it is now possible to calculate quality-adjusted life years for economic evaluation in Japan when the SF-6Dv2 has been used

  • Health-related quality of life and caregiver burden of pediatric patients with inborn errors of metabolism in Japan using EQ-5D-Y, PedsQL, and J-ZBI

    Open Access•Keiko Konomura, Chikahiko Numakura et al.•ARTICLE•Quality of Life Research•2024

    The HRQoL of patients with IEM without developmental disabilities in our study was similar to that of the general Japanese population. The HRQoL of patients with IEM with developmental disabilities was low and associated with a tendency towards an increased burden of care

  • Minimal important differences of EORTC QLQ-C30 for metastatic breast cancer patients

    Open Access•Takuya Kawahara, Naruto Taira et al.•ARTICLE•Quality of Life Research•2022

    We provided the MIDs of the QLQ-C30 using both patient- and clinicians-reported anchors measured in a randomized trial of Japanese patients with metastatic breast cancer. We recommend patient-reported anchors for anchor-based estimation of MID. Our results can aid patients and clinicians, as well as researchers, in the interpretation of QLQ-C30

  • Japanese preference weights of the Adult Social Care Outcomes Toolkit for Carers (Ascot-Carer)

    Open Access•Takeru Shiroiwa, Hiromi Nakamura-Thomas et al.•ARTICLE•Quality of Life Research•2022

    We established Japanese preference weights for ASCOT-Carer states, the first weights of an Asian country. The estimated utilities can contribute to the measurement of caregivers' social care-related QoL and perform of cost-effectiveness analyses

  • Estimation of Lifetime Qalys Based on Lifestyle Behaviors

    Open Access•Shinichi Noto, Shota Saito et al.•ARTICLE•International Journal of…•2021

    Various lifestyle behaviors have been known to affect health-related quality of life (HRQL) and life expectancy. However, the impact on quality-adjusted life years (QALYs), which can be used for health economics, has not been clarified. The purpose of this study was to estimate the impact of lifestyle behaviors on lifetime QALYs. We first examined the relationship between lifestyle behaviors and HRQL as measured by the EQ-5D-5L among 4000 partici…

  • Development of Japanese utility weights for the Adult Social Care Outcomes Toolkit (Ascot) SCT4

    Open Access•Takeru Shiroiwa, Yoko Moriyama et al.•ARTICLE•Quality of Life Research•2019

    We successfully obtained Japanese utility weights for ASCOT SCT4. This will contribute to the measurement and understanding of social care outcomes

  • Psychometric properties of the Japanese version of the EQ-5D-Y by self-report and proxy-report

    Open Access•Takeru Shiroiwa, Takashi Fukuda et al.•ARTICLE•Quality of Life Research•2019

    The EQ-5D-Y demonstrates reliability and validity among children/adolescents and their parents in Japan. Construct validity of the EQ-5D-Y by self-report was confirmed through comparisons with the PedsQL. Proxy responses to the EQ-5D-Y were more reliable compared to the self-report results, but construct validity was not confirmed in the proxy version

  • Long-term health status as measured by EQ-5D among patients with metastatic breast cancer

    Open Access•Takeru Shiroiwa, Takashi Fukuda et al.•ARTICLE•Quality of Life Research•2016

    Our findings suggest that the EQ-5D index value was higher in patients treated with S-1 during first-line chemotherapy. Considering non-inferiority of S-1 in terms of OS, obtained quality-adjusted life years may be greater in the S-1 arm

  • Japanese population norms for preference-based measures

    Open Access•Takeru Shiroiwa, Takashi Fukuda et al.•ARTICLE•Quality of Life Research•2015

    The Japanese population norms of three preference-based QOL measures were examined for the first time. Such information is useful for economic evaluations and research examining QOL score

  • Health utility scores of colorectal cancer based on societal preference in Japan
