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. Two studies using two independent samples were conducted, assessing more proximal constructs, such as love and sex mindset in Study 1 (N = 380; female = 195) and more distant ones, such as loneliness and problematic pornography use in Study 2 (N = 703; female = 360). Structural equation modeling revealed that love (βRAS-1 =.55; p <.01; βRAS =.71; p <.01), sex mindset beliefs (βRAS-1 =.18; p <.01; βRAS =.13; p <.01) and loneliness (βRAS-1 = −.35; p <.01; βRAS = −.37; p <.01) had significant positive and negative associations with RAS and RAS-1, respectively; while problematic pornography use did not. These results suggest that RAS-1 may be an equally adequate instrument for measuring relationship satisfaction as the RAS with respect to proximal and distal correlates. Thus, RAS-1 is recommended to be used in large-scale studies when the number of items is limited.
