Identifying and challenging interpersonal myths

Surface and test the beliefs that prevent you from asking for what you need or saying no.

Why it works

Interpersonal ineffectiveness is often maintained by implicit rules ("asking for help means I’m weak," "saying no will destroy the relationship"). These beliefs function as cognitive avoidance: by predicting catastrophe, they prevent the behavior that would disconfirm them. Naming and testing the belief is the entry point to behaving differently.

How to do it

1. Before a conversation you’ve been avoiding, ask: "What am I telling myself will happen if I ask / say no?"
2. Write the belief explicitly: "I believe that if I ask for more time, they’ll think I’m incompetent."
3. Rate your confidence in that belief (0–100%) and ask: "What evidence would I need to update this?"
4. Identify one piece of evidence from past experience that contradicts the belief.
5. After the conversation, record what actually happened vs. what the belief predicted.

Evidence

Cognitive restructuring of interpersonal beliefs is a core CBT component with robust evidence across anxiety disorders, where such beliefs most commonly prevent effective interpersonal behavior. DBT incorporates this as part of its broader cognitive work. (rct)

Evidence is for cognitive restructuring broadly; DBT’s interpersonal myth-busting is a thematic application of that principle rather than a separately trialed protocol.

Common mistake

Listing myths without tracking the outcome of the test — which means the belief system never accumulates disconfirming evidence and remains as strong as before.
