“Roles are generally understood patterns of behavior that are accepted by family members as part of their individual identities. Usually, roles can be identified by their labels, which denote both formal roles that are socially sanctioned (e.g., grandparent, mother, father, brother, sister) and idiosyncratic roles that evolve over time within a specific family context (e.g., comedian, scapegoat, caregiver).” (p. 200)
