Relationship satisfaction and sexual satisfaction: a longitudinal study of individuals in long-term relationships.

Abstract

This study examined the association between relationship satisfaction and sexual satisfaction over time to provide evidence about possible causal explanations for the association between two variables. Eighty-seven individuals in long-term relationships completed measures of sexual satisfaction and relationship satisfaction at 2 times 18 months apart. There was only limited evidence, based on exploratory analysis, to support either the hypothesis that changes in a relationship satisfaction lead to changes in sexual satisfaction or the hypothesis that changes in sexual satisfaction lead to changes in relationship satisfaction. However, sexual satisfaction and relationship satisfaction wer found to change concurrently. The quality of intimate communication accounted for part of the concurrent changes in relationship satisfaction and sexual satisfaction. I discuss the results in terms of the need to develop more complex models depicting the longitudinal associations between relationship satisfaction and sexual satisfaction.
