Final answer:
The two dimensions studied in FACES are adaptation and cohesion. These dimensions evaluate a family's flexibility in structure and roles, as well as the emotional bonds among family members, which are important in social psychology.
Step-by-step explanation:
The two dimensions studied in the Family Adaptation and Cohesion Evaluation Scale (FACES) are adaptation and cohesion. Adaptation refers to the ability of a family to change its power structure, role relationships, and relationship rules in response to situational and developmental stress. Cohesion refers to the emotional bonding that family members have toward one another and the degree of individual autonomy a person experiences in the family system. Understanding these dimensions is crucial for social psychology, which focuses on how individuals interact and relate to others within various contexts, including familial settings. FACES helps to assess and compare the flexibility and connectedness within family units, which are essential for family functionality and individual well-being.
