Developing the Japanese version of the Southampton Nostalgia Scale

Abstract

Nostalgia is a sentimental longing for a one’s past. It is an emotion that is known to contribute to multiple adaptabilities. We conducted three studies to develop the Japanese version of the Southampton Nostalgia Scale (SNS), which assesses how often people experience nostalgia on a daily basis. Study 1 indicated that the factor structure of the Japanese version and the original version of the SNS are similar and that the Japanese version of the SNS has acceptable test-retest reliability. Study 2 revealed that the factor structure of the Japanese version of the SNS is stable regardless of age. Finally, Study 3 showed that the pattern of correlational relationships of the Japanese version with explicit variables is similar to the original version of the SNS. These results indicate that the Japanese version of the SNS has acceptable validity and reliability.
