Which skill is essential for maintaining healthy relationships?

Interpersonal communication is essential for maintaining healthy relationships because it involves the ability to effectively express feelings, thoughts, and needs while also being able to listen and respond to others. Healthy relationships rely on open dialogue, trust, and mutual understanding, which are all developed through strong interpersonal communication skills. This skill helps individuals convey their feelings and establish boundaries, enabling constructive conversations, resolving conflicts, and deepening connections with others. While the other skills mentioned—problem-solving technology, health literacy, and advocacy techniques—play important roles in various contexts, they do not focus specifically on the interaction and personal connection critical to nurturing relationships. Thus, interpersonal communication stands out as the foundational skill necessary for fostering healthy interpersonal dynamics.
