A two-study validation of a single-item measure of relationship satisfaction: RAS-1

Abstract

Research addressing relationship satisfaction is a constantly growing area in the social sciences. The aim of the present investigation was to examine the similarities and differences between the seven-item Relationship Assessment Scale (RAS) and the single-item measure of relationship satisfaction (RAS-1), using proximal and distal constructs as correlates.

Structural equation modeling revealed that love (βRAS-1 =.55; p
