Differentiation of self is a foundational concept in family systems theory, pioneered by Dr. Murray Bowen. It refers to an individual's ability to maintain their sense of self within the context of relational ties, balancing emotional and intellectual functioning. A welldifferentiated person can engage in intimate relationships without losing their autonomy, while those with lower differentiation might find their emotions and identity heavily influenced by others. Differentiation plays a crucial role in how we navigate interpersonal challenges, from managing conflicts to establishing boundaries. Understanding this concept offers valuable insights into fostering healthier, more resilient relationships, allowing individuals to remain connected yet distinct.
