Navigating Life Stage Differences as couples with significant age gaps in Marriage: Goals and Priorities

This study examines how couples with significant age differences navigate non-synchronous life stages to set shared goals and priorities. Grounded in life course, socioemotional selectivity, dyadic interdependence, and resource-exchange perspectives, the research models Goal Alignment and Priority Fit (GAPF) as a function of structural differences and relational processes. Using a cross-sectional, explanatory design, couple-level surveys from age-gap marriages (≥10 years) were analyzed with hierarchical regression. Structural predictors included absolute age gap, a composite Life-Stage Dissimilarity Index, and perceived resource asymmetry; relational processes comprised communication quality, perceived equity/fairness, social support, and stigma exposure, with controls for marriage duration, prior marriage, children, health, and religiosity. Results indicate that life-stage dissimilarity and resource asymmetry are negatively associated with GAPF, whereas communication quality and perceived equity are strong positive predictors; social support is also positive and stigma negative. Absolute age gap shows little direct effect once structural implications are modeled. Interaction terms reveal buffering: high communication and stronger social support attenuate the adverse association between large age gaps and alignment, and perceived equity mitigates the impact of life-stage dissimilarity. The final model explains approximately 56% of variance in GAPF, underscoring that process factors outweigh structural markers. Findings suggest that couples can convert divergent horizons into coordinated, sustainable priorities through explicit planning talk, engineered fairness, and mobilized support networks.
