Commentary on Manne et al.: Using the Interdependence Model to Understand Spousal Influence on Colorectal Cancer Screening Intentions: a Structural Equation Model

Excerpt

Preventive colorectal cancer screening can significantly reduce mortality, but unfortunately, the participation in screening is still relatively low [1]. Although existing individual level models (e.g., health belief model) have increased our understanding of colorectal cancer screening behavior, the empirical evidence for the associations between many individual level factors and screening behavior is still limited [2]. Manne and colleagues [3] argued convincingly that a greater understanding of the role of one's significant other in screening intentions might help improve screening rates. The dyadic approach posits that members of couples are interdependent and influence each other's attitudes, behaviors, and health outcomes [cf. 4]. Put differently, participation in screening is not based only on individual factors but also on the interaction with one's intimate partner. In line with this idea, they found agreement with respect to screening practices in 65% of the couples. …
