Gender Differences in Variability in Intimate Relationship Satisfaction: A Secondary Analysis and Meta-Analysis.

Area of Science:

• Psychology
• Sociology
• Relationship Science

Background:

• Intimate relationship satisfaction is a key area of interest regarding gender differences.
• Previous research primarily focused on average differences (means) between genders, potentially overlooking other distributional aspects.

Purpose of the Study:

• To investigate gender differences in the variability (variances) of intimate relationship satisfaction.
• To test the "greater female variability hypothesis," positing higher female variability, especially at lower satisfaction levels.

Main Methods:

• A secondary analysis of the Household, Income and Labour Dynamics in Australia (HILDA) survey data (N=2,711 married couples).
• A meta-analysis of 171 studies spanning 20 years and involving 84,976 participants across 33 countries.

Main Results:

• Both the HILDA analysis (variance ratio [VR] = 1.42) and meta-analysis (VR = 1.19) found significantly greater variability in relationship satisfaction among females compared to males.
• Analysis of Australian data indicated that gender differences in variability were more pronounced at lower levels of relationship satisfaction.

Conclusions:

• Findings support the "greater female variability hypothesis."
• The study highlights that focusing solely on mean differences underestimates the full scope of gender differences in intimate relationship satisfaction.
• Greater female variability in satisfaction suggests diverse experiences within intimate relationships for women.
