[A Japanese version of inventory of orientation toward privacy]

Marshall (1974) and Pedersen (1979) theorized and studied Orientation toward Privacy, but the concept has not been explored extensively in this country. In this study, a Japanese version of their Inventory of Orientation toward Privacy was constructed. In Study 1, translated items of the inventory were examined to see whether they had the same dimensions as the original scale. The results indicated that the dimensions were similar, except an "Anonymity" factor. In Study 2, excluding anonymity items, a 21-item Japanese version was constructed, incorporating Iwata's (1987) findings as well. Factor analysis revealed seven factors, Free will, Intimacy with Friends, Reserve, Intimacy with Family, Seclusion, and Isolation. Finally, in Study 3, the new Inventory was administered to another sample, and its factor structure re-examined. The structure proved to be reasonably stable, and it therefore may be concluded that the scale meaningfully measured Orientation toward Privacy.
