Which client behavior would most likely indicate the use of the defense mechanism known as splitting?

The behavior that most clearly demonstrates the defense mechanism known as splitting is the tendency to view one individual as completely worthy or perfect while perceiving others as entirely inadequate. This can be seen in the scenario where a client believes one particular nurse is perfect while others are inadequate. Splitting is a primitive defense mechanism often associated with certain personality disorders, particularly borderline personality disorder. It involves dichotomous thinking, where a person fails to integrate the positive and negative aspects of themselves and others, leading to an all-or-nothing outlook.

In this case, the client’s view of the nurse as flawless indicates an inability to see the nurse as a multifaceted individual with both strengths and weaknesses, reflecting the essence of splitting. This behavior can contribute to unstable relationships and emotional conflicts, as individuals may shift from idealizing someone to devaluing them.

Other behaviors listed—such as self-harming, seeking validation from multiple partners, and frequent arguments with family members—do not specifically illustrate the fundamental characteristic of splitting, which is the black-and-white perception of people. While these behaviors may indicate different kinds of stress responses or coping mechanisms, they do not embody the same kind of dichotomous thinking inherent in splitting.
