Need for uniqueness represents the need for people to feel different and distinguish themselves from others. Two major scales exist that measure this need: the Need for Uniqueness scale (NfU; Snyder & Fromkin, Citation 1977) and the Self-Attributed Need for Uniqueness scale (SANU; Lynn & Harris, Citation 1997b). We propose here a French version of both scales. Through a dual approach of exploratory and confirmatory factorial analyses, we investigated the scales' structure in student samples from two French-speaking countries (France and Switzerland, N= 1,348) as well as measures of internal and external validity. Both scales presented good psychometric properties in French. Additionally, we investigated differences between the scales, as literature suggests that the NfU relies mostly on public and risky displays of uniqueness, whereas the SANU focuses on private and more socially acceptable means to acquire a feeling of uniqueness. Differences arose in the links with several personality characteristics (emotionality, extraversion, agreeableness, sensation seeking, and self-consciousness), suggesting that the NfU corresponds rather to a need to demonstrate uniqueness through public displays and the SANU to a need to feel unique through more private means. We discuss implications for research and provide advice on choosing by the scale most appropriate to the researcher's aims.
