Enrich marital inventory: a discriminant validity and cross-validation assessment

Area of Science:

• Psychology
• Family Studies
• Marital Therapy

Background:

• Assessing marital quality is crucial for clinical intervention and understanding relationship dynamics.
• Existing instruments require validation for clinical utility and accuracy in diverse populations.

Purpose of the Study:

• To evaluate the discriminant validity and clinical utility of the ENRICH marital inventory.
• To determine the predictive power of relationship dynamics versus background factors on marital satisfaction.

Main Methods:

• A discriminant validity study was conducted on a national sample of 5039 married couples.
• The sample was randomly split into a primary and cross-validation group.
• Discriminant and regression analyses were used to assess the ENRICH scales' effectiveness.

Main Results:

• The ENRICH inventory accurately discriminated between happily and unhappily married couples (85-95% accuracy) using both individual and couple scores.
• Results were successfully cross-validated with a separate sample.
• Relationship dynamics, as measured by ENRICH scales, were significant predictors of marital satisfaction, unlike background factors.

Conclusions:

• The ENRICH marital inventory demonstrates strong validity and clinical utility for assessing marital satisfaction.
• The findings support a multidimensional approach to understanding marital quality, emphasizing relationship dynamics.
• All ENRICH scales, except for equalitarian roles, proved significant in discriminating marital happiness.
