To this end, 200 older couples in Japan and 220 in the US were recruited through paid vendors and completed the questionnaire online. Couples were eligible if husbands were 70 years or older and wives were 60 years or older. A six-factor model, in which Compensatory Primary Control was subdivided into two factors, fit the data best; its factorial invariance was confirmed among the four subsamples. Compensatory Secondary Control was more strongly associated with subjective well-being in American couples than in Japanese couples, although the associations between well-being and the other five OPS factors were similar in the two countries. Future research on this six-factor model will be able to examine how these control strategies function in different cultures.

This study is linked with the survey of private elementary and junior-high schools, that began in AY1993. The study, first, reconsiders the justification for the existence of Christian schools in Japan. We feel this study is necessary as Christian schools seem to be dying out as a result of thing like a decrease in the number of Christian teachers and a decrease in the number of students interested in attending this type of school. The second motivation for the survey is more general one: to determine the School Identities of private schools, facing a crisis that the number of students is decreasing in Japan, by reconsidering the spirit behind the founding of a private school. The make-up of the spirit behind the founding of a private school are varied; each school lays stress on...

However, the association between maternal mental health, cortisol profile, and fetal growth remains unclear. This study assessed the cortisol awakening response (CAR) and diurnal cortisol slope (DCS) as the cortisol profile. Healthy pregnant women (N 44, 20 mid-term, 24 late-term; mean age, 29.3 years) participated in this study. Participants mental health was assessed using the General Health Questionnaire, and saliva samples were collected eight times a day for cortisol assessment. The latent growth curve analysis of diurnal cortisol changes using Hierarchical Linear Modeling showed that the intercept and the negative slope were significant. The effects of these intercepts and slopes on the gestation period and birth weight were examined through multiple regression analyses. The results showed that only DCS had a marginally negative association with infant s birth weight (β .52, p .10), after controlling for confounding factors. The DCS might be a better tool for assessing the mental health status during pregnancy, which could also be a better predictor of the birth weight than CAR.

Data for this research came from a national probability sample of 2200 persons aged 60 and over in Japan. Structural equation models were evaluated within the context of two types of social networks: (a) persons who had a spouse and children (n=1299), and (b) those with children only (n=677). Between these two networks, the links among social support, negative relations, and mental health were contrasted. The effects of various sources of social support and negative interactions on mental health vary depending on the specific dimension of mental health as well as the nature of social networks. Among older Japanese who are married with children, social support from spouse has a greater association with positive well-being than social support from children and others. However, cognitive functioning is uncorrelated with all sources of positive and negative social exchanges. In contrast, among those without a spouse, only greater support from children is significantly correlated with higher positive well-being, less distress, and less cognitive impairment.

This study examined the relationships of self-regulation and marital climate with the emotional well-being of both actors and partners among older Japanese couples. Through a mail survey, 498 older couples with husbands (aged in their 70s) and their wives (aged 60 or over) responded to a questionnaire comprising measures of selective optimization with compensation (SOC), tenacious goal pursuit and flexible goal adjustment, marital climate, and emotional well-being. The results of hierarchical linear modeling showed that positive interpretation was associated with not only their own lower depressive symptomatology and higher life satisfaction but also those of their partners. Furthermore, tenacious goal pursuit was beneficially associated with older adults' life satisfaction. Marital climate was positively related to emotional well-being and the association was larger among wives than among husbands. However, contrary to expectations, use of an optimization strategy was negatively linked to partners' life satisfaction, but not actors'. Besides confirming the apparent benefits of self-regulation for actors' well-being, self-regulation could be beneficially or detrimentally related to partners' well-being. To be happy in old age, it seems more important for individuals to care for their spouses and create a favorable marital climate than to pursue their own goals exclusively. There remains, however, a need to simultaneously examine the associations of both intrapersonal (self) and interpersonal (collective) regulatory processes with well-being.

To estimate the item functions of 12 items in each of the 4 subscales, 340 responses to the initial survey and 280 responses to the retest survey conducted 7 weeks later were obtained from Japanese older adults. Item fit information, item-total correlations, and stability of item difficulties were used to select the appropriate items in each subscale. Test-retest and internal consistency reliability were found to be optimal in all of the refined subscales. These subscales were related to internal control, subjective well-being, and personality traits, but not to social desirability. Thus, the psychometric properties of this Japanese SOC questionnaire were verified. This study also indicated the possibility of using the Rasch model to refine the SOC questionnaire in other cultural settings.
