“…The most widespread studies focus on the link between couple interactions and romantic satisfaction, showing that positive couple interactions are related to higher relationship satisfaction (e.g., Gottman and Krokoff, 1989 ; Rogge et al, 2006 ; Friend et al, 2017 ). Other studies have explored the link between couple interactions and outcomes, such as (1) depressive symptoms, in which negative interactions were related to higher reports of depressive symptoms (e.g., Brown and Harris, 2012 ); (2) family functioning, in which conflictual power dynamics in couple interactions were associated with lower family functioning (e.g., Lindahl et al, 2004 ); and (3) children’s reports of perceived threats and insecurity toward interparental conflict, in which negativity in parental conflict was linked with children’s perceptions of threats and insecure family representations (e.g., Zemp et al, 2016 ). Among this body of research, couple interactions have been investigated at various life stages, such as in the transition to marriage (e.g., Markman et al, 2010 ), transition to parenthood (e.g., Tanner Stapleton and Bradbury, 2012 ), or in elderly couples (e.g., Story et al, 2007 ).…”
