A new scale measuring Relational, Individual, and Collective self-aspects (RIC) was developed. The RIC Scale consists of ten questions each followed by three options reflecting the three self-aspects. Respondents rate each option in terms of its applicability to the self, yielding three subscale scores and revealing the relative prominence of each self-aspect. Two samples of university students (N1 = 170, N2 = 214) were used to develop and refine the scale. Analyses supported the reliability and validity of the three RIC subscales. Each self-aspect correlated in predicted ways with several existing scales. The RIC Scale also proved useful in assessing gender differences in self-aspect prominence. Validity of the three-part model of the self and implications for future research are discussed.
