Socioeconomic Status and Mental Illness in Japan*

Abstract Since the pioneering work of Faris and Dunham (1938), a number of studies in the United States have documented an inverse association between socioeconomic status (SES) and mental illness both at the aggregate and the individual levels, and both for the treated and the general population. However, there are few studies of whether this relationship holds in other countries. This study examines socioeconomic characteristics and mental illness in Japan, which has a very different social stratification system from that of the United States. It was found that, at the aggregate level, the “inverse” association between socioeconomic characteristics and the rate of treated mental illness does not hold in Japan. Instead, the relationship is curvilinear: mental illness is higher in districts with large numbers of blue collar and upper white collar workers than in districts with large numbers of lower white collar workers. The effect of SES on mental illness operates through economic stress embedded in the macro social context. Because different social structures lead to different patterns of economic stress, the inverse relationship between socioeconomic status and mental health cannot be assumed to hold in all countries.     

Multiple roles and mental health in cross-cultural perspective: the elderly in the United States and Japan

This paper examines how multiple roles affect the mental health of the elderly in Japan and the United States, two countries with vastly different cultures. Hypotheses were drawn based on the cultural differences in role experiences, and these hypotheses are tested by analyzing nationally representative samples of the elderly in these countries. The results show that Americans are more likely to be involved in roles related to family, work, and community, while the Japanese are more likely to be involved in only those roles related to family and work. Multiple roles are also found to be less beneficialfor the mental health of Japanese elderly compared to American counterparts. National differences in the effects of individual roles and role configurations on mental health are also documented. Overall, the results show the importance of broad cultural contexts for understanding the relationship between roles and mental health.     

Selection of variables and neighborhoods for spatial enhancement of thermal infrared images

The Landsat TM sensor tor rhrrmal infrared measurement has lower spatial resoltion than that of other six measurements. Nishii et al (1996) proposed a procedure to corrct the measurement by a linear combination of remaining high-resolution measurements. To find an efficient combinationof measurements, the averaged information) criteria based on AIC are purposed. Then the efficiency of the procedure is assessed through SSE by using actual TM data.     

Family structure and well-being at older ages in Japan

The family structure of older Japanese is projected to change dramatically as a result of very low fertility, increasing levels of non-marriage, childlessness, and divorce, and declining intergenerational co-residence. To provide an empirical basis for speculation about the implications of projected increases in single-person and couple-only households, we use two sources of data to describe relationships between family structure and the physical and emotional well-being of Japanese men and women aged 60 and above. We find that marriage is positively associated with self-rated health and emotional well-being among older men but not women. In contrast to expectations, however, we find only limited evidence that the presence of children contributes to well-being. Taken as a whole, our results suggest that declines in marriage may have negative implications for the well-being of older Japanese men while the implications of declines in fertility and intergenerational co-residence may be less than popularly believed.     

Social Support and the Mental Health of Family Caregivers: Sons and Daughters Caring for Aging Parents in Japan

The prevalence of depressive symptoms among family caregivers has been documented as a serious social problem that could threaten the lives of the elderly and their family caregivers. Social support is considered to be a promising remedy for this problem, although a comprehensive examination of the availability and effectiveness of social support that includes both formal and informal support across multiple dimensions remains limited. In addition, little research has been conducted in Japan on gender differences in stress processes. This study tried to fill those gaps by analyzing recent survey data on sons and daughters who are caring for their elderly parents. The results indicate that sons and daughters have similar levels of formal and informal support for daily care and advice, while there are some gender differences in regard to the availability of other types of social support. It was also found that many types of informal support were significantly associated with a lower caregiver burden for daughters, although this was not necessarily the case for formal support. General instrumental support from formal sources was even associated with higher levels of distress. For sons acting as caregivers, daily caregiving support was the only formal support that was significantly associated with their lower level of distress. Issues of formal support are discussed, in order to reduce the psychological burdens borne by sons and daughters who care for their parents at home.
