Purpose: The importance of human dignity in care is well-recognized. Care recipients' experiences with undignified care have been reported in many countries. However, few studies have measured these situations quantitatively, especially as there are no tools applicable to inpatients receiving ordinary daily care. This study aimed to develop a valid and reliable Inpatient Dignity Scale (IPDS) that can measure inpatients' expectations of and satisfaction with dignity in daily care. Methods: We conducted a three-phase research project: item generation and a preliminary survey with 47 items related to patients' dignity in Japan, a main survey with 36 items with deliberate translation into English in Singapore, and a confirmatory survey with 35 items in England, with 442, 430, and 500 inpatients as participants in questionnaire surveys, respectively. Data from each survey were processed using factor analysis. Results: Authors obtained a scale with a four-factor structure with acceptable reliability: (F1) respect as a human being, (F2) respect for personal feelings and time, (F3) respect for privacy, and (F4) respect for autonomy. Conclusion: The Inpatient Dignity Scale can be periodically used by hospital administrators or nurses to preserve inpatients' dignity in daily care by monitoring inpatients' views regarding their expectations of and satisfaction with dignity.

<P><B>Abstract</B></P> <P>Interfacial modification (IM) plays a vital role in boosting the performance of perovskite solar cells. Herein, we demonstrate a new strategy in which zinc sulfide (ZnS) is used as an interfacial modifier between mesoporous-TiO<SUB>2</SUB> (mp-TiO<SUB>2</SUB>) and a CH<SUB>3</SUB>NH<SUB>3</SUB>PbI<SUB>3</SUB> absorber layer <I>via</I> the successive ionic layer adsorption and reaction method. The layer thickness of ZnS was optimized, and its effects on the conduction band position, interfacial charge recombination, and photovoltaic performance were investigated. Our results revealed that an ultrathin ZnS layer on mp-TiO<SUB>2</SUB> helps in suppressing backflow of electrons, effectively reducing interfacial charge recombination and facilitating electron transfer. Our best performing perovskite solar cell device using the mp-TiO<SUB>2</SUB>-ZnS achieved a power conversion efficiency of 14.9%, with an open-circuit voltage of 1.02 V, short-circuit current density of 19.05 mA cm<SUP>−2</SUP>, and fill factor of 75.43%. Our simple ZnS IM approach proves that interface engineering could be a key strategy in improving the performance of perovskite solar cells.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Interfacial modification can improve the performance of perovskite solar cells. </LI> <LI> Ultrathin ZnS as an interfacial modifier is deposited on the mesoporous TiO<SUB>2</SUB> ETL. </LI> <LI> The ZnS-modified TiO<SUB>2</SUB> device shows a power conversion efficiency of 14.9%. </LI> <LI> ZnS significantly reduces interfacial charge recombination and enhances charge extraction. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
