This commentary draws on Shaver and Mikulincer's (2012) article to discuss key aspects of adult attachment, family theory, and research. First, a reflection is presented on why the historical development of attachment theory calls for a better understanding of the role of the whole-family context. Second, the issue of the cross-fertilization of research traditions related to attachment theory and family systems theory is addressed. Third, a brief overview of research on attachment and family processes is presented. Finally, to illustrate the relationship between attachment and whole-family variables, the particular example of family rituals is discussed. More precisely, a mediational hypothesis is discussed, whereby attachment security is linked to positive outcomes for families via the development of meaningful family rituals.
