Abstract

Objective: The objective of the study was to translate the revised dyadic adjustment scale into Chinese and evaluate its psychometric properties in gynaecological cancer patients and their male partners.

Methods: A cross-sectional design with a random subsample re-tested at the one-week interval was adopted. Gynaecological cancer patients and their partners were asked to complete the Chinese version of the revised dyadic adjustment and quality of marriage index. Internal consistency, test-retest reliability, convergent validity, structural validity and known-group validity was assessed.

Results: A total of 252 participants (i.e., 126 female patients and 126 male partners) were recruited. The Chinese version of the Revised Dyadic Adjustment showed good internal consistency (Cronbach's α = 0.85), test-retest reliability (r = 0.88), known group validity and adequate convergent validity with a significant positive correlation (r = 0.60) with the Quality of Marriage Index. Confirmatory factor analysis indicated an acceptable model fit to a second-order three-factor structure (GFI = 0.913, RMR = 0.046, CFI = 0.932).

Conclusions: The Chinese version of revised dyadic adjustment demonstrated good reliability and acceptable validity in gynaecological cancer patients and male partners. The scale can be used to assess the effectiveness of clinical nursing services for couples on their relationship and to compare marital satisfaction and adjustment between China and other parts of the world.
