[Relationship between the perceived benefits of working and emotional exhaustion among older assistant care workers: A cross-sectional study].

Objectives This study is intended to clarify the perceived benefits of working among older assistant care workers employed in geriatric health service facilities and examine the relationship between perceived benefits and emotional exhaustion.Methods We analyzed data from a mail survey of older assistant care workers employed in geriatric health service facilities that the Japan Association of Geriatric Health Services Facilities conducted in 2020. In this survey, those aged ≥60 were defined as older assistant care workers. Responses were obtained from 1,606 older assistant care workers at 599 facilities. The dependent variable was the emotional exhaustion subscale of the Japanese version of the Burnout Questionnaire. The independent variables were the seven benefits of working as an assistant care worker: 1) I can contribute to society; 2) I am connected to society; 3) I have a sense of purpose in life; 4) I am earning the income I expected since I started working as an assistant care worker; 5) I am learning about care; 6) It has maintained and improved my health; and 7) I can use my time effectively. Latent class analysis (LCA) was performed using these seven benefits as independent variables. Multiple regression analysis was performed using emotional exhaustion and the perceived benefits as dependent and independent variables, respectively. The missing values were supplemented by the multiple imputation method.Results Overall, 1,601 responses were analyzed after excluding 5 respondents who did not answer all the questions. Four patterns were identified from the LCA results: the "benefit-full type," who perceived all benefits; the "benefit-less type," who perceived few benefits; the "benefit-extroverted type," who perceived social contribution and connection as benefits; and the "benefit-introverted type," who perceived health maintenance and improvement and time utilization as benefits. The multiple regression analysis showed that emotional exhaustion scores were higher for the "benefit-extroverted" and "benefit-less" types than for the "benefit-full" type (b=2.465, P<.001 and b=1.931, P<.001, respectively). No difference was found in the case of the "benefit-introverted" type (b=0.050, P=.851).Conclusion The perceptions of diverse and introverted benefits were associated with lower emotional exhaustion scores among older assistant care workers. Future intervention studies are needed to examine whether obtaining diverse or introverted benefits can decrease the emotional exhaustion score.
