Mental Health During the COVID-19 Pandemic in Japan: Applying Topic Modeling in Daily Life Descriptions.

The novel coronavirus disease pandemic is threatening not only physical but also mental health. Although some recent quantitative studies have been conducted and revealed the influence of the pandemic on mental health and its relevant factors, it is impossible to obtain and explore all possible variables strongly related to mental health. Therefore, we attempted to adopt a bottom-up approach using text mining of participants' narratives. We examined how participants' descriptions of daily life during the pandemic were categorized into various topics, and which topics were related to their mental health in a sample of 776 Japanese citizens in the general population over 18 years old. Results of a topic modeling with 2,594 unique words provided nine topics (mask, physical symptoms, children, infection anxiety, disinfection items, economic influence, remote work, going out, and change of lifestyle). Those who wrote about economic influence, physical symptoms, and disinfection items experienced lower life satisfaction and higher depression and negative affect, whereas those who mentioned their children were likely to have higher life satisfaction. This study highlighted that monitoring the mental health of individuals with economic impacts and physical symptoms may reduce the damage of COVID-19.

Socio-Economic Marginalization and Compliance Motivation Among Students and Freeters in Japan.

This study examines the compliance motivation of students and Freeters when facing a marginalization risk situation evoked by priming. Freeter (part-time employers), NEET (not in education, employment, or training), and Hikikomori (social withdrawal) represent the socio-economically marginalized population in Japan. People at higher risk of becoming NEET and Hikikomori have shown a motivation pattern deviant from mainstream Japanese culture, including lower willingness to conform to in-group members, thus showing less cultural fit (Norasakkunkit and Uchida, 2014). In this study we explore the effect of the macro socio-economic situation (job-hunting prospects being good or bad) on individual's compliance motivation in both students and Freeters. Sixty-five Kyoto University students and 74 Freeters were randomly assigned to one of the two priming conditions (marginalization risk or non-marginalization) before completing the NEET-Hikikomori Risk (NHR) scale and measurements of compliance motivation to conform to in-group members or to be self-consistent (Cialdini et al., 1999). Twenty-three control group students and 22 control group Freeters were also recruited online for comparison. Results showed that marginalization risk priming led to lower tendency to be self-consistent among students, but did not lead to lower tendency to conform to in-group members. For Freeters, marginalization risk priming led to higher compliance motivation to conform to in-group members. The results confirmed the framework proposed by Toivonen et al. (2011) that both Freeters and students in Japan have ritualist reactions, continuing to maintain the cultural norms despite the difficulty of attaining the cultural goals.

Novel psychosocial factor involved in diabetes self-care in the Japanese cultural context.

AIMS/INTRODUCTION: Recent evidence shows that cultural context can influence the management of diabetes mellitus. The aim of the present study was to examine the relationship between interdependence, which is valued in the Eastern cultural context, and diabetes self-care behavior in Japanese patients with type 2 diabetes mellitus. MATERIAL AND METHODS: We carried out a cross-sectional survey of 161 Japanese adults with type 2 diabetes mellitus using well-established questionnaires. The association of an interdependent tendency with diabetes self-care activities was analyzed using multiple regression analysis. RESULTS: Diabetes self-care activities had a negative correlation with interdependent tendency (r = -0.16, P = 0.047), and they had positive correlations with age (r = 0.42, P < 0.001), emotional support (r = 0.25, P = 0.001) and diabetes self-care support (r = 0.36, P < 0.001). When patients were divided into two groups at the median age (68 years), multiple regressions showed that interdependent tendency (ß = -0.20, P = 0.048), male sex (ß = -0.24, P = 0.023), emotional support (ß = 0.22, P = 0.028) and diabetes self-care support (ß = 0.39, P < 0.001) were significant determinants of diabetes self-care activities only in the younger group. CONCLUSIONS: Interdependence might influence diabetes self-care behavior, and intervention focusing on support from close others might lead patients to more successful care among Japanese adults with type 2 diabetes mellitus, especially those aged <68 years.
