Three studies describe the development and validation of a measure of the r
elational-interdependent self-construal, which is defined as the tendency t
o think of oneself in terms of relationships with close others. Study 1 rep
orts the development, psychometric properties, and tests of validity of thi
s new measure. Individuals who scored high on the Relational-Interdependent
Self-Construal (RISC) Scale characterized their important relationships as
closer and more committed than did individuals who scored low on this meas
ure (Study 1) and were more likely to take into account the needs and wishe
s of others when making decisions (Study 2). In Study 3, using a dyadic int
eraction paradigm with previously unacquainted participants, the partners o
f persons who scored high on the RISC scale viewed them as open and respons
ive to their needs and concerns; these perceptions were related to positive
evaluations of the relationship.
