The relationship between positive affect (PA), negative affect (NA) and reported use of problem-focused or emotion-focused coping strategies was investigated in a longitudinal study. Japanese undergraduates (200 men and 270 women) completed a version of the PANAS (Watson, Clark, & Tellegen, 1988) and the situational version of the General Coping Questionnaire (Sasaki & Yamasaki, 2004). These two measures were administered twice, five weeks apart (T1 and T2). The results showed some significant sex differences. Higher PA at T1 was associated with greater reported use of cognitive reinterpretation as a coping strategy at T2 only for men, whereas greater use of cognitive reinterpretation at T1 was associated with higher PA at T2 only for women. These results suggest that there is no mutually reciprocal relationship between PA and use of cognitive reinterpretation as a coping strategy.

Previous research has shown that positive affect (PA) is associated with the coping strategies of "searching for and finding positive meaning." The purpose of this study was to investigate the relationship between the coping strategy of "finding positive meaning" and PA using an intervention method. Additionally, inasmuch as previous research has revealed that PA is associated with physical and mental health status, the current study measured health status in order to carry out a preliminary test as to whether PA increased by the intervention can also improve health. Participants in the intervention group (Japanese graduate students; 13 men and 16 women) reported the most stressful event during the past 3 days and its positive meaning, while those in the control group (13 men and 15 women) reported the most stressful event alone. Both groups reported twice a week for 5 successive weeks using e-mails. Three questionnaires, the Japanese version of the Positive and Negative Affect Schedule scales for measuring positive and negative affects (NA), the situational version of the General Coping Questionnaire for coping strategies, and the Japanese version of the General Health Questionnaire for health status, were administered to all participants just before the start of the intervention, after the conclusion of the intervention, and at the 5-week follow-up session. Results revealed that the "finding positive meaning" coping strategy and PA were enhanced by the intervention in the follow-up for men and women with no changes in NA. For the health scales of the General Health Questionnaire, no significant group-related effects were observed. Thus, the intervention had no significant influence on NA or health status. Implications of these findings for future research are discussed along with a few limitations in this study.

The present purpose was to investigate the effects of social support on the relationship between coping by expressing emotions and depression in women. Japanese undergraduate students (N = 218) completed four self-report questionnaires: the dispositional and situational versions of the Emotional Coping Questionnaire which measures the mode of expression as being either to self as in a diary or to others as in telling a friend, the Social Support Scale to evaluate received support, and the Center for Epidemiologic Studies-Depression Scale. Analysis showed that expression of emotions to self in both dispositional and situational coping had significant positive correlations with depression, especially for women who scored high on depression, and expression of emotions to others in both dispositional and situational coping were significantly positively correlated with social support. However, no significant mediation effects of social support in emotional expression and depression were found. Limitations and topics for research are discussed.

Relationships between emotional experiences and health and adjustment are influenced by many variables, with emotional suppression (ES) being one of the most influential factors. In the current study, we examined the effects of affect and ES on short-term life satisfaction (LS) measured over the previous week. We also considered the dimension of activation status for both positive affect (PA) and negative affect (NA). The final sample included data collected from 398 undergraduates (184 men and 214 women). Participants answered six questionnaires, two of which were used for another study. All of the tests were of Japanese versions and were answered with regard to the previous week's experiences. Results showed that LS was positively associated with PA and negatively with NA, but that the positive association was stronger for activated PA than deactivated PA, while the negative association was stronger for deactivated NA than activated NA. Furthermore, an interactive effect between deactivated NA and ES on LS was significant in men, where post hoc tests demonstrated that deactivated NA was more negatively associated with LS when ES was higher. This study suggests that activated and deactivated affect differ in their effects on LS. In addition, it is likely that the detrimental effect of deactivated NA on LS is larger when NA is more strongly suppressed. The necessity of interventional research along with the limitations of this study is discussed for future research.
