Development and psychometric properties of the Couple Interaction Pattern Scale

This study developed the Couple Interaction Pattern Scale (CIPS) based on the interpersonal theory, comprising five subscales: friendly complementary (FC), hostile complementary (HC), mutual hostile-dominant (MHD), friendly-dominant eliciting hostile-submissive (FDHS), and hostile-dominant eliciting friendly-submissive (HDFS). The psychometric properties of the CIPS were examined through three independent studies. Study one conducted item reduction and preliminary analysis using a sample of 662 married individuals, with an additional 80 married individuals for test–retest reliability assessment. Study two validated the scale through 1207 married individuals. In study three, the effect of couple interaction pattern (CIP) on marital quality was analyzed among 310 newlywed couples using the actor–partner interdependence model (APIM). Results supported the construct validity, acceptable internal consistency, and test–retest reliability of the CIPS. Besides, concurrent validity was also proved by associations with conflictual communication patterns, marital quality, stability, emotional connection, and perceived partner support. APIM analysis also supported the association between CIP and marital quality.
