How long does therapy take?Short-term vs longer-term therapy explained

There's a question people often want to ask me before therapy has even started:

"How long is this going to take?"

It's a perfectly reasonable question.

You're committing time.

You're committing money.

You may be fitting appointments around work, children and everything else already competing for space in your diary.

And, presumably, you don't want to be in therapy for the rest of your life.

Some people are almost apologetic about asking.

They don't need to be.

If you were paying someone to help with almost anything else, you'd want some idea of the timescale.

The difficulty is that therapy isn't a course of antibiotics.

I can't responsibly say:

"Six sessions. You'll be sorted by Thursday."

But neither do I agree with the idea that therapy must be an indefinite journey with no destination and no meaningful way of knowing whether anything is changing.

So the useful answer to "How long does therapy take?" is:

Long enough to understand what's happening and create useful change, but not longer simply because therapy has become a habit.

How long that is depends enormously on why you've come.

Therapy can take weeks, months or longer

There isn't a standard number of counselling sessions.

BACP says most therapy happens in regular sessions of around 50 minutes, with frequency and number agreed according to the person's circumstances. Its client guidance describes brief or short-term therapy as sometimes being limited to roughly six to 12 sessions. (BACP)

Some structured therapies are more clearly time-limited. The NHS currently says CBT will usually involve around 5–15 sessions, depending on what it's being used for. (nhs.uk)

Other therapy can continue for months or longer.

None of those figures tells you what you need.

That's where this becomes more interesting.

Understanding your brain: change isn't measured in sessions

Imagine two people both come to therapy because they're anxious.

The first says:

"I started a new job three months ago. I'm putting enormous pressure on myself, I can't switch off and I've started dreading work."

The second says:

"I've worried about almost everything for as long as I can remember. I avoid situations, constantly seek reassurance and anxiety affects my work, relationships and sleep."

Same word.

Anxiety.

Completely different histories.

It would make little sense to assume they need exactly the same treatment for exactly the same length of time.

The label doesn't determine the timescale.

We need to understand:

• what is happening;

• how long it's been happening;

• what's maintaining it;

• what you want to change;

• what you've already tried;

• what else is happening in your life;

• and how you respond to the work.

• 
  

This is one reason I don't particularly like the question:

"How many sessions does anxiety take?"

Anxiety doesn't attend therapy.

A person does.

And people are considerably more complicated than labels.

The Horizon insight: The Change Equation

I think there are four broad things that affect the length of therapy:

Problem + Pattern + Purpose + Practice

Problem: What are we actually trying to address?

Pattern: How established or complicated is it?

Purpose: What does successful therapy mean to you?

Practice: What happens between our sessions?

Put simply:

Therapy duration isn't just about how serious something feels. It's about what we're trying to change and what keeps it going.

Let's look at those separately.

1. What have you actually come for?

Some people arrive with one clearly defined issue.

A difficult decision.

A recent separation.

Workplace stress.

A confidence problem.

A particular fear.

A recurring conflict.

They can describe what isn't working and what they'd like to be different.

That gives therapy a relatively tight focus.

Other people arrive saying:

"Honestly? I don't know."

They feel flat.

Disconnected.

Anxious.

Angry.

Exhausted.

Relationships aren't working.

Work isn't satisfying.

They know something is wrong but don't yet understand how the pieces fit together.

That initial understanding may itself be a significant part of the therapy.

Neither client is "worse".

They're simply starting in different places.

2. How long has the pattern existed?

This matters, but perhaps not quite as people imagine.

Something you've been doing for twenty years isn't automatically going to take twenty years to change.

Brains learn.

Brains also relearn.

But established patterns can take time to recognise and practise changing.

Suppose you've spent years automatically avoiding conflict.

You might understand in one session why you do it.

That's useful.

But understanding something intellectually on Tuesday doesn't guarantee you'll behave differently when your partner challenges you on Friday night.

That's where practice comes in.

Insight can happen in a session. Change has to survive real life.

 Alan's perspective: I don't believe therapy should automatically take years

I've spoken with people who arrive believing they're signing up for some enormous excavation of their entire life.

Sometimes longer-term work is appropriate.

But I don't start from the assumption that everybody needs it.

One of the beliefs I've developed through practice is that people can sometimes begin noticing meaningful differences much sooner than they expect when they're given the right understanding and practical tools.

That isn't the same as promising a quick fix.

I don't believe in those either.

It's about being specific.

If somebody hasn't felt like themselves for months because work has gradually swallowed their life, we may not need to analyse every year they've lived since primary school before we can start changing something.

We can ask:

What's happening now?

What disappeared?

What's maintaining this?

What could we change?

Then we try something.

And we see what happens.

For me, therapy needs to earn the time somebody is giving it.

What is short-term therapy?

Short-term therapy usually has a clearer focus and an agreed or expected number of sessions.

BACP describes brief or short-term therapy as sometimes having a maximum of six to 12 sessions, although different approaches and services define it differently. (BACP)

This can work well when there is a reasonably identifiable problem or goal.

For example:

"I need to manage my anxiety before presentations."

"I've become overwhelmed at work and need to change how I'm coping."

"My relationship has ended and I'm struggling with it."

"I've lost confidence after redundancy."

The work isn't superficial simply because it's shorter.

Focused therapy can still go deep.

The difference is that we know what we're trying to accomplish.

What about CBT?

CBT is generally a structured, relatively short-term approach.

The NHS says people will usually have 5–15 CBT sessions, although the actual number depends on the problem being treated. Sessions involve looking at difficult situations, identifying links between thoughts, emotions and behaviour, and practising different responses between appointments. (nhs.uk)

That final part matters.

If you spend one hour a week learning something and the other 167 hours repeating exactly the same pattern, progress may be slower.

Therapy doesn't only happen in the therapy room.

The room is where we understand, plan, practise and review.

Life is where we discover whether it works.

What is solution-focused therapy?

Solution-focused brief therapy deliberately concentrates more on solutions, strengths, goals and what is already working than on spending extensive time exploring the historical causes of a problem.

BACP describes brief therapy as short-term work focused on positive change and notes that some forms can be effective within a small number of sessions. (BACP)

I like elements of this approach because sometimes people don't need another hour explaining everything that's wrong.

They've become experts in the problem.

What they haven't worked out is:

"What would different actually look like?"

That's where a more solution-focused conversation can be useful.

When might longer-term therapy make sense?

Sometimes the work genuinely needs more space.

Perhaps there are several interconnected difficulties.

Perhaps the same relationship patterns have repeated throughout your life.

Perhaps there is significant trauma.

Perhaps you're trying to understand aspects of yourself that developed over many years.

Perhaps therapy is uncovering something more complex than the issue that initially brought you through the door.

Or perhaps your objective isn't simply symptom reduction. You want a deeper exploration of identity, relationships or long-standing patterns.

Longer-term therapy can allow that work to develop without forcing everything into an arbitrary deadline.

BACP notes that some people use a small number of sessions for a specific issue while others choose longer-term work for deeper patterns and experiences. (BACP)

The key word for me is choose.

Longer therapy should have a reason.

⚠ Common misunderstanding: "Longer therapy must be better therapy"

No.

Nor does shorter automatically mean more efficient.

The number of sessions tells you very little about the quality of the work.

Ten unfocused sessions aren't automatically better than six focused ones.

Twenty sessions aren't automatically more thorough than twelve.

Equally, forcing complicated work into six sessions because six sounds efficient isn't good practice either.

The useful question isn't:

"What's the fewest sessions I can get away with?"

It's:

"Are these sessions continuing to move me towards what I came here for?"

That is something therapist and client should be able to discuss openly.

What I see every week

One of the most interesting moments in therapy comes when someone says:

"Actually, I think I'm OK."

They almost look as though they need my permission.

They don't.

If we've done what we came to do, that's good news.

I don't believe successful therapy means creating somebody who thinks:

"I can't cope without my therapist."

Quite the opposite.

I'd rather someone eventually thinks:

"I understand myself better. I know what to look for. I have tools that work. I can handle this."

That's progress.

Therapy shouldn't become another thing you're frightened to leave.

How do we know when enough might be enough?

Don't wait for a life in which nothing difficult ever happens.

You'll be waiting a very long time.

Instead, look at what has changed.

Perhaps:

• the original problem has reduced;

• you understand what triggers it;

• you recover more quickly;

• you recognise patterns before getting pulled into them;

• you've learnt strategies you can use independently;

• your relationships have changed;

• you're making decisions differently;

• you're functioning better;

• or you simply feel more like yourself.

Sometimes you then identify another area you'd like to work on.

Fine.

But that should be a conscious decision, not therapy quietly continuing because Tuesday at 4pm has become part of the furniture.

The Horizon progress question

There's one question I think is worth asking periodically:

"If therapy is working, what should now be happening outside this room?"

That's where progress becomes measurable.

If you came because you couldn't say no at work, are you setting boundaries?

If you came because you were withdrawing from friends, are you reconnecting?

If you came because you were constantly overthinking, are thoughts consuming less of your day?

If you came because you and your partner couldn't communicate, are the conversations changing?

If absolutely nothing outside the room changes over a reasonable period, we should be curious about that.

Maybe we need more time.

Maybe we're working on the wrong thing.

Maybe the approach needs adapting.

Maybe another form of support would suit you better.

"Therapy takes time" shouldn't become an excuse for never reviewing whether therapy is helping.

How often should you have therapy?

Weekly sessions are common, particularly at the beginning. BACP says therapy usually takes place in planned, regular sessions, while the exact frequency and total number depend on individual circumstances. (BACP)

But frequency can vary.

Some people work fortnightly.

Some structured treatments have their own recommended schedule.

Others may reduce frequency as therapy progresses.

There are practical considerations too.

Work.

Money.

Family.

Energy.

Travel.

What matters is agreeing something that gives the work enough continuity to be useful.

Fitting therapy around a professional life

This is where I think therapy services sometimes forget what people's lives actually look like.

If you're running a business, leading a team or working a demanding job, adding another weekly obligation can feel like the opposite of reducing stress.

So practical fit matters.

Online therapy can remove travelling time.

A regular slot can stop therapy being repeatedly pushed aside by work.

Some people prefer appointments at the beginning or end of the working day.

And sometimes fortnightly work may be appropriate.

But there's a trap here too.

"I'm too busy for therapy."

may occasionally mean:

"The very thing I'm seeking help with is also preventing me from making space to address it."

If work has consumed every available hour, finding one hour for yourself may be part of the work rather than an inconvenience around it.

What if I feel better after three sessions?

Excellent.

Tell your therapist.

Don't assume you're supposed to stay for another three months because therapy must be complicated.

We might decide:

• you've achieved what you wanted;

• we want another session or two to consolidate it;

• there's more you'd like to explore;

• or we finish and you know you can return if circumstances change.

Good endings matter.

BACP advises that endings should normally be discussed and planned rather than arriving unexpectedly, particularly in time-limited therapy. (BACP)

What if nothing has changed after ten sessions?

Talk about it.

Please don't sit politely for another ten sessions wondering whether you're allowed to mention it.

Ask:

"What do you think we're trying to achieve?"

"How are we measuring progress?"

"Do you think this approach is working?"

"Should we be doing something differently?"

A competent therapist shouldn't be threatened by those questions.

They're useful questions.

One small change this week: define your finish line

If you're considering therapy, don't begin by deciding how many sessions you need.

Instead, finish this sentence:

"I'll know therapy is helping when..."

Be concrete.

Perhaps:

"...I can go to bed without thinking about work for two hours."

"...I'm seeing my friends again."

"...I can disagree with my partner without either shutting down or exploding."

"...I stop assuming every mistake means I've failed."

"...I wake up and actually want to do something."

That's far more useful than choosing an arbitrary number of sessions.

Because now we have somewhere to go.

Frequently asked questions

How many therapy sessions does the average person need?

There isn't a meaningful universal number. Duration depends on the issue, therapeutic approach, goals, complexity and response to treatment. BACP says session numbers should be agreed according to individual circumstances. (BACP)

How many CBT sessions are usually needed?

The NHS currently says CBT usually involves around 5–15 sessions, depending on what it is being used for. (nhs.uk)

Is six sessions of counselling enough?

It can be for some people and some focused problems. BACP describes short-term therapy as commonly involving a limited course such as six to 12 sessions. For other difficulties, six sessions may not be sufficient. (BACP)

Can therapy work after only a few sessions?

Some people notice useful changes quickly, particularly when the problem is focused and the work gives them an understanding or strategy they can apply immediately. That doesn't mean every problem can or should be resolved quickly.

Can I stay in therapy for years?

Some people undertake long-term or open-ended therapy. The important questions are why you're continuing, whether it remains useful and whether the arrangement is appropriate for your needs.

Should therapy be weekly?

Weekly is common and provides continuity, but frequency varies by approach, circumstances and stage of therapy. Discuss this with your therapist rather than assuming one schedule suits everybody. (BACP)

Is short-term therapy superficial?

Not necessarily. Short-term work can be highly focused and meaningful. Its defining feature is usually a tighter focus or agreed timeframe, not an unwillingness to discuss difficult material.

Does person-centred therapy take longer than CBT?

It isn't useful to assume a fixed duration purely from the modality. CBT is generally structured and time-limited, whereas person-centred counselling may be short-term or open-ended. The actual duration depends on the work and the setting. (nhs.uk)

Can I stop therapy whenever I want?

Yes, although where possible it's usually useful to discuss the decision with your therapist and plan the ending rather than simply disappearing. BACP specifically advises that endings should be anticipated and discussed. (BACP)

What if my therapist thinks I should continue but I don't?

It's your therapy. Ask why they recommend continuing and consider their reasoning, but the decision isn't theirs alone. A good therapist should be able to discuss benefits, limitations, alternatives and ending openly.

The Horizon reflection

I understand why people want a number.

Six sessions sounds manageable.

Twelve gives you a plan.

"Let's see" can sound suspiciously like an open-ended direct debit.

But therapy isn't better because it's long.

And it isn't better because it's short.

It's better when it has a purpose.

Sometimes a handful of conversations can help somebody see a problem completely differently.

Sometimes understanding comes quickly but changing the pattern takes practice.

Sometimes the first problem turns out to be attached to something much bigger.

And sometimes somebody has done what they came to do and it's simply time to finish.

I don't think the objective of therapy should be keeping somebody in therapy.

The objective is helping them reach a point where they understand themselves better, have something useful they can actually apply and are more able to manage life without needing us.

So if you're wondering:

"How long will therapy take?"

I'd ask another question first:

"What needs to be different for you to no longer need it?"

Once we understand that, we have something far more useful than a number.

We have a direction.

• A focused recent problem may require different work from several long-standing interconnected patterns.

• Understanding can happen quickly; practising a new response may take longer.

• Therapy should be reviewed rather than allowed to continue indefinitely without a clear reason.
