^a I = investment, S = relationship satisfaction, Q = quality of alternatives, C = commitment, and SD = standard deviation.

^b Correlations for the primary relationship appear above the diagonal line; correlations for the secondary relationship appear below the diagonal. Correlations along the diagonal are between the primary and secondary partners on the same variable.

^c **p < .01.
