Differentiation of self is a psychological concept that refers to an individual's ability to maintain their sense of self while navigating emotional connections with others. It involves balancing personal beliefs and values with the influence of family and social relationships. This process helps individuals develop autonomy and emotional resilience. In the context of family dynamics, particularly in family therapy, differentiation allows members to express their thoughts and feelings without losing their identity. It is essential for healthy relationships, as it promotes effective communication and reduces anxiety in interpersonal interactions, fostering a sense of independence and self-awareness.
