The ageing of the population has resulted in an increase in the demand for long-term care services for older people, but with limited resources, its challenges have also been highlighted. Although factors affecting the willingness of older people to engage with long-term care services have been widely reported, however, systematic review has not synthesised the evidence, and its associated factors remain unclear. This systematic review aims to study and synthesise the best available evidence on the potential factors related to the willingness of older people to engage with long-term care services. Eight electronic databases were comprehensively searched from inception to January 2021: the Cochrane Library, PubMed, Web of Science, CINAHL, Wanfang Database, China Knowledge Resource Integrated Database (CNKI), Weipu Database (VIP), and Chinese Biomedical Literature Database (CBM). The original literatures were screened according to selection criteria. Two researchers used 11-item checklist recommended by the Agency for Healthcare Research and Quality to evaluate the quality of the included literatures. And the review used narrative synthesis to integrate factors related to the willingness of older people to engage with long-term care services. In total, 7794 studies were screened and 35 studies were included in this review. Among them, 23 studies were rated as moderate quality and 12 was high quality. Data synthesis identified that age, education, number of children, living arrangements, the relationship with children, primary caregivers, place of residence, social support, household income, medical insurance, activities of daily living ability and spiritual comfort should all be taken into account when establishing the appropriate long-term care service model or formulating relevant policies. However, many factors remain undetermined and require more rigorous original literature support. And multiple areas can be also considered in the future studies, especially psychological factors.

Bibliotherapy is an important part of art therapy and many publications regarding bibliotherapy have been published in the past. However, there has none about the scientometric study to systematically analyze the development and emerging research trends on bibliotherapy. Therefore, we performed a scientometric investigation to describe trends of this theme. All publications related to bibliotherapy published from 1980 to 2020 were identified and selected from Science Citation Index Expanded, Social Sciences Citation Index, and Arts & Humanities Citation Index of Web of Science Core Collection. VOSviewer was used to create collaborative network plots of countries, institutions, and authors and to perform cluster analysis of keywords. A total of 703 articles were searched, and we retrieved the 100 most cited articles published by 146 institutions from 15 countries in 57 academic journals. The United States occupied a leading position in the field of bibliotherapy and Linkoping University was the most productive institution. Journal of Consulting and Clinical Psychology was the most productive journal. Andersson G, Carlbring P, and Cuijpers P may have an important influence on bibliotherapy research. The applications in depression, anxiety, panic disorder, insomnia, and aphasia are the hot themes. This scientometric review provided a comprehensive understanding of the bibliotherapy research using quantitative and qualitative methods, which can provide references for researchers in the bibliotherapy field. As investigators continue to work, we look forward to the development of bibliotherapy efficacy and the implementation form and steps.
