Cross‐Cultural Adaptation and Psychometric Properties of the Japanese Version of the Attitudes toward Singlehood Scale ^{1, 2, 3, 4}

Abstract The nine‐item Attitudes toward Singlehood Scale (AtSS) is a newly developed measurement for people to self‐report their manners toward staying single. The original English‐version AtSS shows sound psychometric properties in the Malaysian and Indian contexts. To necessarily adapt the AtSS in cross‐cultural studies, we developed the Japanese version of the AtSS (AtSS‐J) and examined its psychometric qualities in a sample of 316 Japanese undergraduate students. The participants answered an online survey consisting of the AtSS‐J, a (single‐item) preference for being single, the Mini‐Social Phobia Inventory, the Single Item Narcissism Scale, and the Satisfaction with Life Scale. Confirmatory factor analysis supports that the AtSS‐J has a second‐order factor structure (error covariance specified between Items 3 and 5) composed of three first‐order specific factors (affect, behavior, and cognition). Both Cronbach's alpha and McDonald's omega estimates indicated good reliability in the AtSS‐J. Moreover, convergent and discriminant validity of the AtSS‐J are evident, while the concurrent validity with life satisfaction as criterion variable showed inconsistent results. Overall, our findings offer preliminary support to the usability of the AtSS‐J.
