Interest in mindfulness in the field of romantic relationships is growing. Drawing from a Self‐Determination Theory (SDT) perspective—which proposes that the basic psychological needs for autonomy, competence, and relatedness are foundational for well‐being—we attempted to map out the complex associations between mindfulness, self‐compassion, other‐compassion, basic need fulfillment in relationships, and increased relationship and sexual satisfaction. A sample of 640 midlife (40–59‐year‐old) married Canadians was recruited from a national panel. To test the associations at a systems‐level, we utilized psychological network analysis based on the premise that the relational and sexual effects of mindfulness are understood as part of a dynamic and multivariate network of associations with other variables. Need fulfillment in relationships (particularly relatedness needs) occupied a central position in the model, connecting mindfulness and self‐compassion with relationship satisfaction and sexual satisfaction. The findings underscored the major importance of SDT in relationships, and the overall structure of the network was consistent with growing theories of mindfulness in relationships. Future research employing longitudinal network models will aid in elucidating this system's operation over time. [ABSTRACT FROM AUTHOR]

Relationship and sexual satisfaction are two central outcomes in the study of relationships and are commonly used in both academia and applied practice. However, relationship and sexual satisfaction measures infrequently undergo specific psychometric investigation. Ensuring that measures display strong psychometric performance is an important but under-tested element of replication that has come under more scrutiny lately, and adequate measurement of constructs is an important auxiliary assumption underpinning theory-testing empirical work. A measurement check-up was conducted, including Confirmatory Factor Analysis (CFA) to test factorial validity, measurement invariance to test for group comparability, and Item Response Theory (IRT) to assess the relationship between latent traits and their items/indicators. This format was used to evaluate the psychometric properties of the Couple's Satisfaction Index (CSI) and the Global Measure of Sexual Satisfaction (GMSEX), two commonly used scales of relationship and sexual satisfaction with a sample of 640 midlife (40–59 years old) married Canadians who were recruited by Qualtrics Panels. Results of CFA suggested that both models were satisfactory. Invariance testing provided robust support for intercept invariance across all the groupings tested. IRT analysis supported the CSI and GMSEX, however, there was evidence that the GMSEX provided somewhat less information for those high on sexual satisfaction. This measurement check-up found that the CSI and GMSEX were reasonably healthy with some caveats. Implications are discussed in terms of replicability and meaning for scholars and practitioners.

Researchers have investigated the directionality between relationship and sexual satisfaction; however, there remains no definitive conclusion. Previous longitudinal studies have not conceptualized relationship and sexual satisfaction as systematic developmental processes and have focused on predicting scores at later time points. Instead, researchers should be concerned with understanding how relationship and sexual satisfaction change together over time. The objective of this study was to use longitudinal data from midlife American marriages to test the directionality of the association between relationship satisfaction and sexual satisfaction. Multivariate latent growth curve modeling of 1,456 midlife Americans married for 20 years from the Midlife in the United States study was used to compare directionality models. Findings support that long-term, stable marriages of midlife Americans at the sample level were characterized by a linear increase in relationship satisfaction over 20 years and a linear decline in sexual satisfaction during the same time frame. A co-change model, wherein relationship and sexual satisfaction changed together over time, fit the data best. Trajectory correlations showed that changes in relationship and sexual satisfaction were strongly interconnected. High initial levels of sexual satisfaction protected against declines in relationship satisfaction over 20 years. Results support that relationship and sexual satisfaction change together over time and highlight that the longitudinal association between these outcomes is dynamic rather than static.
