This document discusses interpersonal relationships, defining them as social interactions between two or more individuals. Interpersonal relationships are important for personal growth, sense of security, and understanding for individuals. For nurses, strong interpersonal relationships can improve team communication and decision-making. Relationships also help patients feel secure and foster trust. Relationships exist in dyads, triads, and groups. Common types include friendships, family, professional colleagues, love interests, and marriage. Relationships progress through different phases and can be hindered by situational, personal, or sociocultural barriers, though effective communication can help overcome obstacles.
