Interpersonal Effectiveness
Interpersonal Myths
Challenge beliefs that sabotage effective communication—replace myths with balanced truths and new behaviors.
Tip: jot notes below, then print or “Save as PDF.”
How to practice it
Move through each step slowly. Notice what the skill asks for and how you can experiment in real life.
1
Identify the Myth
Write the belief that gets in your way (e.g., “If I say no, they’ll leave,” “Emotions make me weak”).
2
Evidence For & Against
List situations that seem to support the myth, then list experiences that contradict it.
3
Balanced Truth
Craft an accurate statement that honors both your needs and the relationship.
4
New Skillful Action
Choose a behavior (DEAR MAN, GIVE, FAST, mindfulness) that reinforces the new belief.
Real-world examples
Try spotting moments like these in your week. Notice how the skill changes the ripple effect of a tough situation.
Myth: Asking for help is selfish
Evidence For: One friend reacted badly. Evidence Against: Many people were glad to assist. Truth: “People can choose to help; asking is respectful when I’m clear.” Action: Use DEAR MAN with a coworker this week.
Myth: Setting boundaries ruins relationships
Evidence For: One partner got defensive. Evidence Against: Other relationships improved with clarity. Truth: “Boundaries create safer connections over time.” Action: Practice FAST while saying no to extra work tonight.

What truth supports both you and the relationship?
