[Objective] Many patients with dementia exhibit behavioral and psychological symptoms of dementia (BPSD) that significantly affect not only them, but also their families and caregivers. This study aims to contribute to the advancement of the relevant research by showing the international trends in BPSD in a systematic way. [Methods] To achieve that, quantitative analysis was conducted using the bibliometric software CiteSpace. [Results] Analysis, which focused on the authors of the cited research, revealed a relatively significant influence of the work of Cummings on the trends. Furthermore, a paper by Kales et al., published in 2015, on the assessment and management of Behavioral and Psychological Symptoms of Dementia, was the most cited. [Conclusion] The paper that proposed non-pharmacological therapy as the primary choice, by Kales et al. (2015) had the most visible impact on the trends in the field. This suggests a shift in the paradigm by promoting the transition from the pharmacological to the non-pharmacological treatments, particularly through the involvement of the family caregivers.

[Objective]The purpose of this study was to show in detail how the concept of the “Welfare for the Aged” was formed during the deliberations of the Diet Proceedings, and the Fourth Subcommittee of the Council of Social Welfare held on June 25th, 1962. [Methods] To conduct the research, the Diet Proceedings from 1920 to 2022 and the Minutes of the Fourth Subcommittee of the Council of Social Welfare, were analyzed using the KJ method and concordance. [Results]The KJ method was used to identify 6 categories, 18 subcategories, and 82 labels. [Conclusion] We found that the formation of the key concepts, such as the “Welfare for the aged,” the three levels of consideration were the ideological level, the legal level, and the implementation/operational level, and the reconciliation of the public and private sectors’ views was important during making the decisions.

[Objective] Certified care workers have to achieve professional autonomy required for all professionals to demonstrate their expertise. This study aims to develop a professional autonomy scale for certified care workers and examine the reliability and validity of the scale. [Methods] An anonymous self-registered questionnaire survey was conducted among 4,000 certified care workers working in 400 special nursing-care homes for the aged nationwide in Japan. Excluding the responses with missing values, 614 responses were included in the factor analysis. [Results] The analysis yielded a scale with 38 items in 7 factors. The Cronbach’s α coefficient to measure reliability was 0.961 for the entire scale. The goodness-of-fit indices were CFI=0.921 and RMSEA=0.055. [Conclusions] It was established that the professional autonomy scale for the certified care workers developed in this study has sufficient reliability and validity.
