BACKGROUND: In occupational health, the maintenance and promotion of workers' health, especially lifestyle motivation-based interventions, have gained considerable attention and are actively implemented. Motivational theories include self-determination theory, and some studies focus on healthy lifestyles. However, the effectiveness of health promotion interventions varies depending on the health awareness and motivation of the participants. Therefore, this study aimed to clarify the processes by which workers are motivated to improve their health and to identify the need for and type of support according to their motivation. METHODS: Using a mixed-research design, an initial questionnaire survey of 94 employees (mean age = 40.97 ± 9.65) at a multicenter company in Japan, followed by semi-structured interviews with 16 employees (mean age = 40.13 ± 9.45) from the high- and low-motivation groups, were conducted. Multiple regression analysis followed by modified grounded theory-based analysis of the results of the first stage was used and the quantitative and qualitative results were integrated. RESULTS: In the first stage, autonomous motivation scores were predicted by the behavioral change stage and relatedness satisfaction/frustration. The second stage revealed that "the process of reflecting and managing one's own health while receiving support and feedback for maintaining and improving health" was the motivational process of workers. Result integration revealed that motivation increased through repeatedly escaping and adjusting to real problems and situational coping until the behavioral change. Despite interruptions during behavioral change, receiving feedback from others could increase motivation and continued behavioral change. CONCLUSION: Regardless of their level of motivation for health behaviors, workers indicated that support from others was essential. The nature of this support was found to range from providing information to offering feedback. Interventions individualized by the identified process could enable customized motivation-driven health guidance.

BACKGROUND: Motivational interventions are used as preventive measures in occupational health. However, existing studies primarily focus on motivation methods and not the stage of motivation-the process from extrinsic to intrinsic motivation. The treatment self-regulation questionnaire (TSRQ) can predict workers' health at each motivational stage. Accordingly, this study examined the reliability and validity of the Japanese version of the TSRQ (Diet and Exercise) in occupational health settings. METHODS: Responses of 912 workers were analyzed. In this study, the Cronbach's alphas were 0.85 for Diet and 0.84 for Exercise after excluding items with low Item-Total correlations. Regarding convergent validity, there was a weak correlation between behavior modification stages and the TSRQ. Regarding structural validity, confirmatory factor analysis was performed assuming a four-factor structure. RESULTS: The goodness-of-fit indices were: Comparative Fit Index (CFI) = 0.94, Tucker Lewis Index (TLI) = 0.92, and Root Mean Square Error of Approximation (RMSEA) = 0.07 for Diet and CFI = 0.92, TLI = 0.91, and RMSEA = 0.08 for Exercise. CONCLUSION: The Japanese version of the TSRQ has a certain degree of reliability and validity. It can measure motivation for Diet and health-related behaviors in occupational health settings. The findings of this study may serve as a basis for promoting primary and secondary prevention.

Abstract Background In the process of community building, it is important to create a place for multigenerational exchanges. To promote multigenerational exchanges in regional locations, it is essential to clarify whether such exchanges are related to government infrastructure, regional characteristics, and social capital, and how these exchanges contribute to community building. Methods A cross-sectional questionnaire study was conducted with representatives from 455 Chiiki no Cha-no-Ma (literal translation “community living room,” and hereafter “Cha-no-Ma”) in Niigata City, Japan. Responses were received from 405 representatives (response rate: 89.0 %), and 401 agreed to participate (4 declined). The survey details included basic information (e.g., date each location was established, frequency of meetings, number of caretakers and participants, qualifications of the representative), activities reflecting local culture, a social capital scale, the effects of the Cha-no-Ma implemented by the representative (12 items), challenges for management (16 items), and the implementation of multigenerational exchanges. Results Most of the age groups that participated in the Cha-no-Ma were elderly, and multigenerational exchanges took place in 125 locations (31.5 %). Items that had a significant connection to the implementation of multigenerational exchanges were “Frequency of meetings” (p < 0.001) and “Activities reflecting local culture” (p = 0.026). Binomial logistic regression analysis indicated that a high frequency of meetings was associated with the implementation of multigenerational exchanges (Odds ratio = 3.839). There was a significantly higher ratio of implementation of multigenerational exchanges when the effects were a “connection with the region” (p = 0.006) and “conversations with different generations” (p = 0.004), and when the challenge was “no support from residents” (p = 0.002). Conclusions Cha-no-Ma participation is low among young people. The following ideas can be considered in order to increase multigenerational exchanges in regional locations. These exchanges may be promoted by increasing the frequency of meetings with qualified personnel and by adding activities that reflect local culture, such as festivals and making local foods. This community-based study clearly indicates that implementing multigenerational exchanges is an important activity for community building because it is related to connection within the community.
