Partnership questionnaire: Factorial structure, gender invariance, and associations with Msi-R and DCI

The objectives of the present study were: a) to examine the factor structure of the Partnership Questionnaire (PFB) through confirmatory factor analyses, b) to test for the invariance of this structure across genders, and c) to analyze the PFB concurrent validity through its associations with the Marital Satisfaction Inventory Revised (MSI-R) and the Dyadic Coping Inventory (DCI) in a sample of 448 Italian couples. Results indicate that PFB presents a gender invariant 3-factor structure (Quarreling,Tenderness, and Sexuality), and correlates significantly, in the expected directions, with the MSI-R and DCI scales.
