Tryt Career Co., Ltd. (Tokyo Headquarters: Shinagawa-ku, Tokyo; Osaka Headquarters: Kita-ku, Osaka; President and Representative Director: Kisei Nishikori) and the Sozo Inoue Laboratory of the National University Corporation Kyushu Institute of Technology (Headquarters: Kitakyushu City, Fukuoka; President: Takuo Yasunaga) have conducted joint research, and their research paper has been published in 'Healthcare', a healthcare field academic journal of MDPI, one of the world's largest open-access academic publishers.
In Japan, where the population is aging rapidly, the need for caregiving staff is increasing sharply, while the turnover rate in the medical and welfare fields remains high. According to the Ministry of Health, Labour and Welfare's '2024 Employment Trends Survey', the number of leavers in the 'medical and welfare' field reached 1,135,000, making it the second-largest industry for leavers nationwide after 'wholesale and retail trade'. Caregiving work involves dense communication and teamwork, suggesting that the workplace atmosphere may play a crucial role in shaping caregivers' job satisfaction.
The Sozo Inoue Laboratory at the Graduate School of Life Science and Systems Engineering (Wakamatsu Campus) of Kyushu Institute of Technology researches the application of AI and IoT in caregiving and healthcare. Meanwhile, Tryt Career, aiming to solve labor shortages primarily in the medical and welfare industries, has expanded its sales bases to 28 prefectures nationwide and is engaged in recruitment and employment support tailored to regional characteristics and needs.
In this study, a questionnaire was administered to 183 care workers working in actual caregiving settings. Using the survey results, the relationships among 'psychological safety', 'personality traits (Big Five)', and 'workplace environment and organizational culture' were evaluated through statistical 'Structural Equation Modeling (SEM)', and the importance of each factor was analyzed using the machine learning algorithm 'XGBoost'.
The analysis revealed that 'psychological safety in the workplace, not the individual's personality itself', had the strongest influence on job satisfaction in caregiving settings. It became clear that personality traits such as high agreeableness or a tendency to feel anxious do not directly determine job satisfaction but indirectly influence it through psychological safety. The data clearly shows that an organizational culture where 'concerns can be openly discussed' is the key to improving workplace satisfaction.
Tryt Career is engaged in industry-academia collaboration initiatives, utilizing data and insights gained from recruitment and employment support in the medical and welfare fields and combining them with the specialized knowledge of academic institutions to aim for more effective and fundamental solutions to social issues. Based on this research, the company will contribute to creating a psychologically safe work environment in care facilities and improving job satisfaction for care workers.
Kyushu Institute of Technology, based on the engineering knowledge and implementation capabilities cultivated since its founding in 1909, is integrally promoting DX and XD in the care and medical fields, centered on the Care XDX Center. By circulating AI/IoT and on-site data, and through initiatives such as those of the Japan Agency for Medical Research and Development (AMED) and the Japan Science and Technology Agency (JST), it contributes to improving the quality and productivity of care, creating new services, and supporting startups.
