The present study examined the relationship between self-reported scores on optimism, social support, and stress and on physical and psychological well-being in 176 Japanese female college students. The significant interactions found among scores on optimism, social support, and stress suggest that individuals who reported higher optimism and social support also rated themselves higher with respect to physical and psychological well-being, regardless of their reported stress.
The present study examined the psychometric characteristics of the three network function subscales (Social Support, Conflict, and Reciprocity) in the Japanese version of the Interpersonal Relationship Inventory. Data from Japanese college students (250 women and 218 men) were analyzed to estimate internal consistency (alphas = .93-.96) and test-retest reliability (rs = .69-.74). To assess construct validity, correlations between scores on the inventory and measures of social support, loneliness, and stress were performed. Results indicated that the Japanese version of the inventory was valid and reliable.
The Flourishing Scale (FS) and the Scale of Positive and Negative Experience (SPANE) are reliable, valid instruments used to assess aspects of well-being such as psychological flourishing and positive and negative feelings. The Japanese versions of these scales (FS-J and SPANE-J) have been shown to have adequate internal consistency and construct validity. Test-retest reliability of the Japanese versions, however, has not yet been assessed. Therefore, the purpose of this study was to assess the test-retest reliability of the Japanese versions. The temporal stability of the factor structure of the Japanese versions was also evaluated. The FS-J and SPANE-J data were collected from 336 Japanese college students in two sessions conducted one month apart. The participants completed the Japanese versions in both sessions. The results indicated acceptable test-retest reliability for the FS-J (0.87) and SPANE-J (0.57-0.60). Simultaneous confirmatory factor analysis supported the temporal stability of the hypothesized factor structures for the Japanese versions over the one-month interval.
