The elusive nature of self-measurement: the self-construal scale versus the twenty statements test.

In the present study, the authors compared 2 frequently used measures to operationalize the construct of the self, namely, the Self-Construal Scale (SCS; T. M. Singelis, 1994) and the Twenty Statements Test (TST; M. Kuhn & T. S. McPartland, 1954), in a sample of 324 male and female undergraduate psychology students of diverse ethnocultural backgrounds. Results demonstrated low intercorrelations between the 2 measures, suggesting that the qualitative and quantitative measures did not evaluate the same construct. A factor analysis of the SCS scale revealed 3 constructs-an independent construct, an interdependent construct, and a power distance or hierarchy construct. Implications for future research included the need for ongoing work in identifying and measuring the constructs of the self.
