Communicating Your Needs: How DBT Interpersonal Effectiveness Skills Help Set Boundaries & Strengthen Relationships

Sometimes the hardest part of relationships isn’t caring for others. It’s caring for yourself within them.

Many of us grow up believing that being kind means always saying yes, often abandoning our own needs in the process. We learn to keep the peace, avoid conflict, and focus on being liked within the relationship.

Over time, this pattern can pull us further and further away from ourselves. Instead of expressing what we truly think or feel, we begin to show a version of ourselves that feels easier for others to accept. While this may protect the relationship in the short term, it often leaves us feeling emotionally overwhelmed, disconnected from ourselves, and unsure how to communicate what actually matters to us.

In Dialectical Behavior Therapy (DBT), we talk about a skillset called Interpersonal Effectiveness, including the ability to ask for what we need while maintaining relationships and self-respect. For many people, these skills don’t come naturally. If we have spent years focused on keeping the peace or making sure others are comfortable, we may never have learned how to communicate our own needs clearly.

A big part of interpersonal effectiveness is understanding boundaries, which are often misunderstood as rules meant to control other people or push them away entirely. In truth, boundaries are about getting clear about what we’re comfortable with, and how we need to take care of ourselves within relationships. Instead of trying to force someone else to change their behavior, boundaries focus on what we will do or what we will accept as a part of our relationship values.

DBT, always practical, offers the tools to help people communicate their needs effectively. One of the most powerful skills is called DEAR MAN, a framework designed to help people ask for what they need. This skill is yours now, too:

1. Describe – explain the situation using clear, observable facts rather than assumptions or accusations. Sticking to

what actually happened helps keep the conversation grounded and reduces the chance that the other person will become defensive.

2. Express – effectively share how the situation has affected you emotionally. This allows the other person to understand the experience from your perspective.

3. Assert – clearly state what you need or what you are asking for. Being direct and specific helps prevent misunderstandings and gives the other person a clear opportunity to respond.

4. Reinforce – focus on explaining why the request matters. This step helps the other person understand the importance of the request and how honoring it could positively impact the relationship.

Appear confident refers to communicating in a clear and steady way, even if you feel nervous internally.

Negotiate- remain open to finding a solution that works for both people, rather than approaching the conversation as something that needs to be won.

Learning to communicate in this way can feel uncomfortable at first, but it works. Speaking up, setting limits, and expressing what matters to you are skills that take practice but that change everything.

Write your script, practice in the mirror, and see what happens. When boundaries are communicated clearly and respectfully, they  strengthen relationships rather than harm them. They create clarity, not ambivalence. And they allow people to show up more honestly, instead of just “keeping the peace.”  Caring for yourself doesn’t push people away. It creates the conditions for connections that feel more balanced, authentic, and supportive for everyone involved.
