In this article you will read about:
The Boundary Building skill in Dialectical Behavior Therapy (DBT) sits inside the Interpersonal Effectiveness module and focuses on learning how to say, “This is okay with me—and this is not,” in ways that protect both your well-being and your relationships. DBT framing emphasizes that healthy boundaries are neither rigid walls nor open floodgates; they are flexible, chosen limits that let in respect, care, and connection while filtering out hostility, manipulation, and overload.
DBT.tools lists Boundary Building alongside DEAR MAN, GIVE, and FAST as one of four core interpersonal skills, highlighting that boundaries are central to getting needs met, ending toxic dynamics, and maintaining self-respect. In practice, you use Boundary Building together with those communication skills to move from vague discomfort or resentment into clear, values-based limits.
What Are Boundaries in a DBT Context?
In DBT-informed writing, boundaries are described as the limits that define where you end and others begin—psychologically, emotionally, and physically. They are the guidelines for how you want to be treated and how you interact with the world.
Common types of boundaries include:
Physical boundaries
How close people can stand, who may touch you, sexual consent, and how you care for your body and physical space.
Emotional boundaries
How much you allow others to influence your feelings, whether you take responsibility for their emotions, and how you protect yourself from emotional abuse or chronic invalidation.
Psychological / information boundaries
What you choose to share about your beliefs, history, and private life, and with whom.
Time, energy, and digital boundaries
Limits around work hours, availability, texting/social media access, and how quickly you respond.
From a DBT perspective, healthy boundaries are flexible: you can open them more in safe, reciprocal relationships and tighten them in unsafe or draining ones.
“Strength does not come from winning. Your struggles develop your strengths. When you go through hardships and decide not to surrender, that is strength.”
"It is not the strength of the body that counts, but the strength of the spirit."
How Boundary Building Fits into DBT
DBT is built around four main skill sets: mindfulness, distress tolerance, emotion regulation, and interpersonal effectiveness (Linehan, 2015). Interpersonal effectiveness, in particular, teaches people to:
Ask for what they need
Say no
Resolve conflict
Maintain relationships
Preserve self-respect
Setting boundaries is woven through all these goals and is explicitly highlighted in DBT-based discussions of interpersonal effectiveness exercises and workshops. DBT.tools even gives Boundary Building its own page and identifies it as one of four interpersonal skill-building activities alongside DEAR MAN, GIVE, and FAST.
DBT-informed programs (e.g., McLean Hospital, SoCal DBT) explicitly teach boundaries as part of learning to communicate needs, say no, and maintain self-respect in relationships.
Types and Styles of Boundaries
DBT-adjacent psychoeducational resources describe boundary “styles” that are highly relevant when teaching the Boundary Building skill:
Nonexistent or very porous boundaries – You rarely say no, share too much personal information, allow others to make decisions for you, and tolerate disrespect or abuse.
Weak or poorly expressed boundaries – You feel resentful and overwhelmed, but your limits stay unspoken or very vague.
Rigid boundaries – You wall off emotionally, avoid vulnerability, and keep others at a distance even when more closeness might be safe or nourishing.
DBT’s Boundary Building material also distinguishes physical, emotional, and psychological boundaries and emphasizes that you can deliberately make them stronger or more flexible depending on the situation.

Why Boundaries Are Often Hard (Especially After Invalidating Environments)
DBT.tools notes that people who grew up in chaotic or dysfunctional families often find boundaries “one of the most uncomfortable sets of clothes to try on,” because early survival strategies depended on being overly compliant, hyper-responsible, or enmeshed.
Similarly, Watershed Counseling describes how invalidating or boundary-ignoring environments can leave people unsure of what they’re allowed to ask for, how to say no, or where they end and others begin—leading to burnout, resentment, or isolation.
In DBT’s biosocial model, this fits the idea that people with chronic emotion dysregulation often lacked consistent modeling of healthy communication and limits; boundaries can feel foreign, “selfish,” or dangerous at first.
Evidence Base: DBT, Interpersonal Effectiveness, and Boundaries
While “Boundary Building” isn’t usually studied as a standalone skill, it sits inside the interpersonal effectiveness skills that have been researched:
A 2023 open-pilot study found that a 3-hour workshop teaching DBT interpersonal effectiveness skills (including assertiveness and limit setting) to nurses improved communication skills, professional fulfillment, and coping, and was rated as acceptable and feasible.
A 2024 trial of DBT interpersonal effectiveness training reported improvements in social functioning and communication competence compared with a control group.
A 2015 systematic review of DBT skills training as a stand-alone treatment found that DBT skills groups (covering interpersonal effectiveness, emotion regulation, and distress tolerance) were associated with improvements across a range of diagnoses and settings.
A 2010 study showed that increased DBT skills use mediates reductions in suicidal behavior, depression, and anger, supporting the idea that skills like boundary setting are mechanisms of change.
Together, these data support teaching interpersonal skills—including boundary setting—as a meaningful part of DBT’s effectiveness for emotion dysregulation and relational problems.
The Boundary Building Skill: Step-by-Step
Notice Boundary “Pain Signals”
Before you can change boundaries, DBT encourages you to notice signals that something is off, such as:
Feeling chronically overwhelmed or drained by others
Frequent resentment (“People always take advantage of me”)
Avoiding calls or messages because you expect demands
Fantasizing about disappearing or “dropping everything”PositivePsychology.com
These emotions are not evidence that you’re “too sensitive”; they are data that your boundaries may be too loose, too rigid, or unclear.
Identify the Type and Strength of the Boundary
Using DBT’s interpersonal boundaries framework, ask:
Is this a physical boundary? (Space, touch, sexual activity, privacy of your body.)
An emotional boundary? (How much someone’s moods or judgments control your feelings.)
A psychological/information boundary? (How much you share, or what topics are off-limits.)
Also consider:
Is my boundary currently porous (too open), rigid, or roughly healthy/flexible?
Simply naming the type and style of boundary helps move you from vague discomfort into something you can work with concretely.
Clarify Your “Go” and “No-Go” Zones
DBT.tools suggests that to set boundaries, you first need to know what is important to you and where your thresholds are—for example, infidelity as a non-negotiable in romantic relationships, or being yelled at as a “no-go” in professional settings.
You can ask yourself:
What behaviors are clearly okay with me in this context?
What behaviors are clearly not okay?
Where do I feel unsure, and what would Wise Mind say?
This step ties boundary work to values: you’re not just reacting to discomfort; you’re protecting what matters most (e.g., respect, safety, autonomy, privacy).
Plan How to Communicate the Boundary (Using DEAR MAN + GIVE + FAST)
Boundary Building in DBT is rarely “just say no.” It’s usually:
Boundary decision (what you want your limit to be)
DBT interpersonal effectiveness skills (how you express and maintain it)
A typical DBT-consistent script might weave together:
DEAR MAN for the structure of the request or limit: describe the situation, express how it affects you, assert the boundary, and reinforce why it’s reasonable or beneficial.
GIVE to protect the relationship: be gentle, show interest, validate the other person’s perspective, and use an easy manner.
FAST to keep self-respect: be fair, avoid unnecessary apologizing, stick to your values, and be truthful rather than making excuses.
Example (time boundary with a friend who calls late at night):
“When I get calls after midnight, I end up feeling exhausted the next day (Describe + Express). I need to stop taking calls after 10 p.m. on weeknights (Assert). If I’m more rested, I’ll enjoy our talks more and be more present (Reinforce). I get that you sometimes feel alone at night (Validate), and I still need to protect my sleep (FAST: stick to values). We can text or schedule a call earlier in the evening (Negotiate).”
Negotiate Boundaries Explicitly (Instead of Only Hinting)
Interpersonal boundaries often shift through implicit negotiation—someone pushes a little, you either go along, say nothing, or resist. DBT’s interpersonal boundaries exercise recommends experimenting with explicit negotiation, especially when your subtle signals aren’t being recognized.Dialectical Behavior Therapy
That might sound like:
“I’m okay talking about work stress, but I don’t want to talk about my dating life in the office.”
“I value your opinion, and I’m not comfortable with you reading my private messages.”
Stating boundaries clearly gives the other person a fair chance to respect them and reduces the “But I didn’t know” dynamic that can muddy relationships.
Case Example: Using the STOP Skill During an Argument
Jordan, 27, has a history of intense anger outbursts in relationships. In past arguments, they’ve yelled, said cutting things they didn’t mean, and once punched a wall. Afterwards, Jordan usually felt ashamed and afraid of being “too much,” which reinforced a cycle of conflict and withdrawal. In DBT, Jordan learned the STOP skill as a way to interrupt that automatic chain.
One evening, Jordan’s partner said, “You never listen to me,” in a frustrated tone. Jordan felt a surge of heat in their chest and an urge to snap back with, “You’re so dramatic, I can’t stand this.” Instead, they remembered: S – Stop. They froze, kept their mouth shut, and didn’t fire off the first angry response.
Next, Jordan T – Took a step back by leaning against the kitchen counter and taking two slow breaths. They imagined mentally stepping back from the scene, as if watching it on a screen. Then they O – Observed: “My heart is racing. My hands are tight. I’m having the thought, ‘I’m being attacked.’ My partner looks upset, not evil.” Simply noticing this helped the urge feel slightly less like a command.
Finally, Jordan P – Proceeded mindfully by asking themselves, “What do I want in the long run? Do I want to win this argument or protect this relationship?” From Wise Mind, they chose to say, more calmly, “I am listening, but I’m getting really triggered. Can we slow down so I don’t say something I regret?” The conversation still wasn’t easy, but it didn’t explode like usual.
Later in therapy, Jordan and their clinician highlighted that the big success wasn’t being calm the whole time—it was using STOP to create a pause. That small gap between urge and action allowed Jordan to choose behavior that fit their values, instead of letting anger drive the moment.
Conclusion
The STOP skill in DBT is a deceptively simple but powerful distress tolerance tool. By breaking crisis moments into four concrete steps—Stop, Take a step back, Observe, Proceed mindfully—it helps individuals pause before acting on intense urges, bringing Wise Mind and other skills into the picture.
Rather than aiming to eliminate strong emotions, STOP focuses on changing what happens between emotion and action. Used consistently, it can reduce impulsive behaviors, protect relationships, and support long-term goals, especially for people living with chronic emotion dysregulation. Within the broader DBT skill set, STOP functions as the gateway skill that creates just enough space to choose a different path—one mindful pause at a time.
FAQ
Most frequent questions and answers about the STOP Skill in DBT
STOP is a quick, four-step DBT skill that helps you pause before reacting impulsively when you’re overwhelmed. It stands for:
S – Stop
T – Take a step back
O – Observe
P – Proceed mindfully
Its purpose is to interrupt automatic reactions (like yelling, self-harming, or storming out) and give you a moment to choose a response that actually helps you in the long run.
Use STOP any time you notice your emotions spiking and you feel the urge to act in a way you might regret, for example:
During heated arguments
When you want to self-harm or use substances
When you’re about to send an impulsive text or post
When panic or shame suddenly surges
If you catch yourself thinking “I have to do something right now,” that’s usually a great moment to use STOP.
That still counts as practice. Even a one-second pause before reacting is a small win. Over time, your goal is to:
Lengthen that pause (with “Take a step back” and “Observe”)
Add even one small mindful action in the “Proceed mindfully” step
You don’t have to do it perfectly for it to be working; you’re training your brain to insert a gap between urge and action.
STOP is often the first move that makes other skills possible. For example:
STOP → then use TIPP to calm your body.
STOP → then use ACCEPTS or IMPROVE to ride out distress.
STOP → then use DEAR MAN to communicate effectively.
Think of STOP as the “gateway” skill that gives you enough space to remember and apply everything else you’ve learned.
Repetition and rehearsal help a lot. You can:
Practice STOP with imagery: mentally rehearse using it in your common trigger situations.
Write “STOP” on a sticky note, phone lock screen, or bracelet as a visual cue.
After real situations (even if they didn’t go well), reflect: “Where could I have inserted STOP?”
The more you practice when the stakes are lower, the more likely STOP will “show up” on its own when things are intense.
