In couple research, dyadic coping (DC) describes verbal and nonverbal behaviors couples use to jointly cope with stress. Ample evidence shows that DC is a robust predictor of relationship satisfaction (e.g., Falconier et al., 2015). While DC has often been assessed using self-report measures, more recent studies have used observational data, i.e., the systematic coding of video-recorded couple interactions according to standardized procedures in the lab. Following a structured interaction paradigm, each individual is asked to tell their partner about a stressor external to the relationship (e.g., job-related stressors). However, a large portion of parental stress appears to originate from events or circumstances which are child-related such as children's behavior or mental health problems. To specifically assess how parents cope with such child-related stress, we modified the original DC interaction paradigm (Bodenmann, 2008). To evaluate the feasibility of this modified paradigm for future research, we are currently conducting a multi-site proof-of-concept study at three different locations (Munich, Vienna, Witten/Herdecke). In a target sample of N = 60 couples with children between the ages of 4 to 16, we aim to test the modified paradigm against the original DC paradigm years to compare both paradigms in terms of their associations with relevant outcome variables on a trait- and state-level (e.g., perceived stress, experienced emotions, relationship satisfaction). In this poster presentation, the feasibility, limitations, and potential benefits of our novel paradigm for future research are discussed.
