This article introduces the Dyadic Coping Inventory (DCI; Bodenmann, 2008) and aims (a) to investigate the reliability and aspects of the validity of the Italian and French version of the original German DCI and (b) to replicate the factorial structure and reliabilities of the scale using a new Swiss German sample. Based on 216 Swiss, 378 Italian and 198 French speaking participants, the factor structure of the original German questionnaire could be replicated in all three groups after excluding two items in the Italian and French version. The Italian and French versions have been proven as reliable as the German version with the exception of the low reliabilities of negative dyadic coping in the French group. Intercorrelations among scales were similar across all three languages groups with a few exceptions. Previous findings could be replicated in all three groups, showing that aspects of dyadic coping were more strongly related to marital quality than to marital communication in the form of avoidance and constructive and demand-withdraw communication. The use of the dyadic coping variables (DCI) in the Actor-Partner Interdependence, the Common Fate, and the Mutual Influence Model is discussed.
