Examining the Relationship Between Preference for Solitude and Subjective Well-Being Among Japanese Older Adults

Focusing on the fact that older adults with positive emotions tend to spend time alone, this study aimed to examine the relationship between preference for solitude and subjective well-being among older adults. In Study 1, we developed a revised version of the Preference for Solitude Scale with a 3-factor structure, unlike the single-factor structure of the original scale. In Study 2, we examined the relationship between preference for solitude and subjective well-being using the revised scale.

We conducted an Internet survey with 210 older adults in Study 1 to develop a revised Japanese scale. In Study 2, to address the possible research method bias in Study 1, we conducted a mail survey with 276 older adults. We examined the replicability of Study 1, confirming metric invariance through multigroup analysis and hypothesis model through path analysis.

The results of the path analysis indicated that "Productivity during solitude" (Factor 3) was positively related with positive affect and life satisfaction, and "Enjoyment of solitude" (Factor 2) was negatively related with negative affect. However, the results of the mediation analysis suggested that preference for solitude was also related to loneliness, and the indirect effect of preference for solitude on well-being was negative.

"Enjoyment of solitude" and "Productivity during solitude" were related to maintaining subjective well-being among older adults, although the effects were marginal. The impact of preference for solitude was mixed in enhancing and decreasing subjective well-being.
