One Line of Sexual Decline? Growth Mixture Modeling for Midlife Sexual Satisfaction

Area of Science:

• Psychology
• Sociology
• Relationship Science

Background:

• Long-term relationship research often assumes a single decline in sexual satisfaction.
• Existing studies lack detailed analysis of diverse sexual satisfaction trajectories over time.

Purpose of the Study:

• To identify and analyze various trajectories of sexual satisfaction in midlife marriages.
• To challenge the cultural myth of inevitably declining sexual satisfaction.

Main Methods:

• Utilized growth mixture modeling with longitudinal data from three distinct datasets.
• Analyzed data from the Flourishing Families Project, Marital Instability Dataset, and Iowa Youth and Families Project.
• Examined trajectories for both wives and husbands in individual and dyadic analyses.

Main Results:

• Identified heterogeneous sexual satisfaction trajectories, including stable high, medium, low, and increasing patterns.
• Observed similarities and some differences in trajectories between wives and husbands.
• Found demographic variables were not strong predictors of these differing trajectories.

Conclusions:

• Sexual satisfaction in midlife marriages is not monolithic and follows diverse paths.
• Understanding these varied trajectories can help couples navigate expectations and counter myths of decline.
• Marital satisfaction and stability generally mirrored sexual satisfaction patterns but were more stable.
