Accept yourself as you are, and work to change. The two sound contradictory; DBT holds that you can't do without either.[3]
Have you had an evening like this? Your partner promised to call, and all that arrives is "Really tired tonight, let's talk tomorrow." You understand they're tired, yet the anxiety shoots straight to the top; you want to stay calm, but your thumbs are already typing. Afterwards you regret it, and wonder: why does something that looks small to everyone else hit me like this?
1The worldview
Dialectical behaviour therapy (DBT) was developed by the American psychologist Marsha Linehan, first for chronically suicidal women diagnosed with borderline personality disorder (BPD). She started with a package of cognitive-behavioural interventions focused on changing thoughts and behaviour, but many patients felt criticised and misunderstood, and dropped out. So she wove acceptance into the treatment: accepting clients as they are, and helping them accept themselves, their emotions and the world around them. Acceptance and change side by side is what makes DBT distinctive.[1,3]
So what is there to change in that evening? DBT understands many difficulties as emotion dysregulation: emotions that come fast, hit hard and fade slowly, without the chance to learn how to regulate them, leave people reaching for quick but destructive ways to cope, such as self-harm. So DBT's aim is not only to reduce dangerous behaviour, but to build, together with the client, a life worth living.[]
Now you know how it sees a person and how it works. The next questions: what is it actually like, does it work, and what is it not for?
What the studies above tested isn't a single kind of session but standard DBT, a whole programme, usually a year long in the research. A few orientation sessions come first, then four parts run together: individual therapy, a skills group, phone coaching and a therapist consultation team, each carrying part of what is described above. Many services offer only part of it (often the skills group); partial versions have less evidence behind them than the full package.[1,3,4,7,17]

Want to try the skills that evening called for? These four steps suit everyday emotional ups and downs; take one or two a week. If self-harm or suicidal thoughts are involved, please walk this path with a therapist.
TreeholeHK's counsellors and clinical psychologists use DBT to fit what you need, alongside other approaches.
DBT started from behaviour therapy and added acceptance and mindfulness. These approaches are its closest relatives.
You can do the exercises on your own. When you're stuck, a trained therapist can take you further.
DBT is often grouped with the "third wave" of cognitive and behavioural therapies: it keeps the methods of behaviour therapy (the change side) and adds mindfulness and acceptance drawn from Eastern contemplative practice (the acceptance side).[4,6]
DBT is a treatment for serious emotional difficulties. If you are thinking of hurting yourself or ending your life right now, please don't face it alone: call The Samaritans' 24-hour line on 2896 0000, or 999 in an emergency.
So why can "let's talk tomorrow" be enough to make emotions spill over? Linehan's biosocial theory points to two things that feed each other over the years: being born emotionally sensitive, and growing up where one's emotions are often dismissed, ignored or punished. The second is called invalidation. It is a loop, not anyone's fault: sensitivity makes emotions spill over, the spill-over draws more invalidation, and invalidation makes it harder still to trust and regulate one's own emotions, so the next time is harder again.
The change side needs an order: that evening is only one of many things, since DBT clients often have many problems at once. So that each session isn't swept along by the latest crisis, individual therapy follows a fixed order: clients record urges, emotions, behaviours and skills used on a daily diary card, the therapist reviews it each week, and work starts from the highest item on the list.[1,3,4]
Alongside this, every session builds behavioural skills (introduced one by one below) to replace the old ways of coping. All of the above is the first stage, for when behaviour is out of control; once it is steadier, therapy turns to deeper pain, such as the after-effects of trauma.
Suicidal and self-harming behaviour, and behaviour that endangers others. When present, it comes first in every session.
"Any thoughts or acts of hurting yourself this week?"
Anything, from client or therapist, that gets in the way of therapy: missed sessions, lateness, an empty diary card; behaviour that wears the therapist out counts too.
"The diary card is blank again this week."
Patterns that seriously damage daily life, such as substance misuse, being unable to work, or money crises.
"Every fight means a sleepless night and a sick day."
2The method
DBT's answer to that loop is dialectics: two opposing forces that are both true and each incomplete, held in tension until a new synthesis appears. "You are doing your best" and "you need to do better" can both be true. Change alone (like that evening's "don't overreact") leaves clients feeling invalidated (the very link in the loop called invalidation); acceptance alone leaves dangerous behaviour in place. So in every session a DBT therapist keeps balancing two kinds of strategy: acceptance answers the invalidation, and change targets the behaviour that sensitivity and dysregulation lead to.[1,3,4]
A11pm. Your partner promised to call, and instead sends: "Really tired tonight, let's talk tomorrow."
With skillsAnxiety still jumps to 90: skills don't make the sensitivity go away
With skillsSTOP first (a skill described below): phone down, step back, notice the body, then choose to reply tomorrow
With skillsThey may still say it; you remind yourself: feeling anxious when a call doesn't come makes sense
3The skills
The skills built in every session come in four sets, learned in a weekly group run like a class: mindfulness, distress tolerance (getting through the peak of pain without making things worse), emotion regulation and interpersonal effectiveness (asking clearly and respectfully in relationships). Individual therapy uses chain analysis and validation to connect the skills to the client's own life. Each link in the loop is a door, and entering by any one of them can interrupt it (that evening could be entered through the emotion, the moment of overwhelm or the relationship), so the skills are grouped by these three doors.
See the emotion clearly in the moment, then judge whether it fits the facts.
Mindfulness is DBT's core skill and runs through the other three. It has two parts: the "what" (observing, describing and fully participating in the moment) and the "how" (non-judgementally, one thing at a time, effectively). The aim is wise mind. Reasonable mind runs on facts and logic, emotion mind is led by feeling, and wise mind is where the two overlap and both are heard. It is the dialectic in a single person.[2,4]
An emotion regulation skill, for when a feeling hits too hard and you suspect you are overreacting, such as the moment "he doesn't care about me" flashes up in that opening evening. The steps: name the emotion, separate facts from interpretations, ask what you fear, how likely it is and how you'd cope if it happened, then see whether the emotion's size fits the facts. If it fits, solve the problem; if not, checking the facts often eases the emotion by itself, and you can go on to the next skill, opposite action.[2]
You said you were on edge all day after Monday's meeting. Would you like to look at it with check the facts?
First, what's the emotion, and how strong, 0 to 100?
What happened? Only what a camera would have recorded.
How did you read that?
After checking the facts, if the emotion doesn't fit them, or acting on it doesn't help, do the opposite of what it urges, all the way, posture and voice included. If shame says hide, opposite action is to lift your head and show up as usual.[2]
Get through the peak without making things worse, then find where a skill could fit in next time.
One of the crisis survival skills in distress tolerance, and the first step on that opening evening: Stop, Take a step back, Observe, Proceed mindfully. The aim isn't to push the emotion down but to leave a gap between urge and action, so you don't make things worse.[2]
Another crisis survival skill, for when the emotion is at its peak and still hard after STOP: use sight, sound, smell, taste and touch to be gentle with yourself through the hardest stretch. It won't solve the problem, but it can stop you doing something that makes things worse while the pain is at its peak.[2]
For a reality you can't change, stop fighting it and acknowledge, fully, that this is how it is. On that opening evening, if tonight's call isn't coming, that can't be changed now, so say "no call tonight" rather than arguing with it. Acceptance isn't approval or giving up: it turns unbearable suffering back into pain you can bear, and frees energy for what can change.[2]
Being validated and learning to validate yourself; asking clearly while keeping the relationship and your self-respect.
DBT's main acceptance strategy: the therapist finds what is valid and makes sense in the client's experience, emotions and thoughts, and says so. Validating isn't approving every behaviour; it answers the "invalidation" link in the biosocial theory, and clients gradually learn to validate themselves. The chain analysis conversation above shows it: the need to know he still cares is validated, the string of messages is not.[1,3]
An interpersonal effectiveness skill: Describe the facts, Express your feelings, Assert your request, Reinforce with what's in it for them, while staying Mindful, Appearing confident and being willing to Negotiate. It works alongside GIVE, for the relationship (be Gentle, act Interested, Validate, use an Easy manner), and FAST, for self-respect (be Fair, don't over-Apologise, Stick to your values, be Truthful). In the check the facts conversation above, the client who wants to ask the manager exactly what to change could script it with DEAR MAN.[2]
The dialogues are illustrative composites, not real clients; skills that stir strong emotion or touch on trauma should be done with a trained therapist.
DBT's evidence is strongest for repeated self-harm, suicidal behaviour and borderline personality disorder. The UK's NICE recommends considering a comprehensive DBT programme for women with BPD for whom reducing recurrent self-harm is a priority, and DBT for adolescents (DBT-A) for children and young people with significant emotional dysregulation who self-harm frequently.[3,18,19]
DBT skills are also widely used for everyday emotion management, but research on skills classes alone is still preliminary. If you are thinking of hurting yourself or ending your life, please call The Samaritans' 24-hour line on 2896 0000 first, or 999 in an emergency; to find out whether DBT suits you, talk it over with a therapist.
DBT deals with suicidal and self-harming behaviour first (see the priorities above), so most studies look at whether that behaviour goes down, not whether an evening of anxiety like the opening one eases. It is one of the most studied psychotherapies for borderline personality disorder. Each item below shows how firm the evidence currently is.
Several controlled trials found that DBT reduces self-harm and suicidal behaviour more than usual treatment, with a modest effect. In one trial that compared it with experienced community therapists, about half as many people in the DBT group made a suicide attempt over two years, and fewer dropped out. But a Cochrane review (a systematic review that pools similar studies and rates how reliable the evidence is) rated the certainty of this evidence as low, meaning the conclusions could well change with new studies, and most participants were women.[9,12,13]
DBT adapted for teenagers helps a little to a moderate degree with self-harm and suicidal thoughts. In a trial of 173 teenagers, DBT was clearly better than the comparison treatment when the six months of treatment ended, but over the following six months the gap was no longer clear. Studies differ quite a lot from one another, and most participants were young women.[15,16]
A trial that took DBT apart found that all three versions (full DBT; individual therapy plus a support group; skills training plus case management) reduced suicide attempts, but versions that included skills training did better at reducing non-fatal self-injury. Another analysis found that people in DBT used far more skills, and that using more skills went along with fewer suicide attempts and less depression. These are hints from only a few studies.[10,11]
What DBT reduces is mainly behaviour: self-harm, suicidal acts and the use of psychiatric crisis services. Across studies combined, there was no clear overall effect on suicidal thoughts. The authors suggest this may reflect DBT's order of priorities, behaviour before thoughts.[12]
DBT does better than usual treatment, but when compared directly with other well-designed treatments built for borderline personality disorder it has not come out ahead: in a trial of 180 people, DBT and general psychiatric management (a clearly structured treatment without DBT's skills training) did equally well. The evidence so far cannot show that DBT beats other specialist treatments.[13,14]
To be honest: the Cochrane review rated all of these DBT findings as low-certainty evidence, from mostly female samples. Most studies compare DBT with usual treatment or a waiting list, so they cannot show that it beats other specialist treatments. DBT is a strong option, not the only answer.[12,13,14]
The evidence above points to some limits. DBT is well researched, but it has costs and open questions: the evidence is mostly low-certainty, it hasn't outperformed other well-specified treatments, and evidence for learning the skills on their own is still preliminary.[13,14,17]
Full DBT means individual therapy and a group every week, usually for a year, delivered by a whole trained team. That is a big commitment for clients and a big investment for services, so not everywhere can offer the full version.
DBT skills classes and self-help exercises are popular, but studies of the skills on their own still have too many methodological limits for strong conclusions. The free exercises here suit everyday ups and downs; they don't replace therapy.
DBT beats usual care, but in a head-to-head trial it did no better than general psychiatric management, another well-specified treatment. When the Cochrane review compared each therapy's advantage over usual care, none clearly stood out. What may matter is a clear structure and theory, not the brand name.
Most trials studied women with BPD, in small samples. Applying DBT to other people calls for more caution.
So, back to that evening: DBT's answer is acceptance and change at once. It is a strong toolkit for serious emotional difficulties, but not the only path; whether it suits you is something to weigh up with a therapist.
A night like that may still come, and the feeling may not shrink; what DBT offers is two sentences you can say to yourself at once: "It makes sense that you feel this," and "what you do next is still yours to choose."
With skillsThe feeling is still strong, but you choose what you do, and the relationship takes one less hit
The "With skills" column uses acceptance and change together. The invalidation link is answered with acceptance (the anxiety makes sense); the dysregulation link with change (a gap between urge and action); the sensitivity itself stays. Doing both at once is DBT's dialectic. That answers the opening question: a small thing becomes a storm when sensitivity and invalidation stack up, not because someone is weak; and inside the storm there is still something to do. Practise making that gap with the STOP skill
So what you fear is losing your job. What facts support that? What facts don't?
Any other possible reasons he said it?
If the worst did happen, how would you cope?
Looking at it now, does the size of the anxiety fit the facts?
Fifty is about right to get you working on the report. What's your next step?
That makes sense. We can use the interpersonal effectiveness skills to write down how you'll ask.
Notice: This conversation shows check the facts. The therapist asks whether the client wants to use the skill, then follows it step by step: name the emotion and its strength, describe only the facts, find the interpretation, ask about the feared outcome and the evidence, imagine coping with the worst case, and finally ask whether the emotion fits. The answer is "partly": the report really does need redoing, so some anxiety makes sense. It drops from 85 to 50, and the conversation turns to solving the problem.
Method based on[2]
A central tool of individual therapy: break one problem behaviour into a chain and see what happened link by link. The chain runs from the vulnerability factors and the prompting event, through each link of thought, emotion, body sensation and urge, to the consequences. Then look together for the link where a skill could go in.[3,8]
Your diary card shows Friday night under "angry messages", with the urge at 5 out of 5. It's the main thing to look at this week. Shall we take that evening apart step by step?
First, let's be exact. What did you do that night?
Earlier that day, was anything making you more easily set off than usual? Sleep, food, other stress?
So you were already running hot. What set it off?
When you read that, what went through your mind?
How strong was the panic? What did you notice in your body?
And then?
Wanting to know he still cares makes complete sense, and in that panic, wanting an answer right now does too. What we're looking for is another way to look after that need that doesn't hurt you both. What happened after?
That matters: in the short term the messages did get a response, so next time the urge comes they're likely to come back. In the long run they bring what you fear closer. Looking at the whole chain, where could you most likely do something different?
Which skill could go there?
Not being sure is normal. Shall we rehearse it now, with that night as the scene?
Notice: This conversation shows chain analysis, on that same opening evening, now taken apart afterwards in the therapy room. The therapist picks the week's top-priority behaviour from the diary card, asks permission, then takes it apart link by link: vulnerability, prompting event, thought, emotion, body, urge, behaviour and consequences. The therapist validates the need to know the partner still cares, not the way it was pursued, and points out that the short-term payoff makes the behaviour likely to return. The client chooses where to put a skill, and promises only to try.
