How long does therapy take, and why there is no shortcut

“And how long does it take?” This is one of the first questions people ask when they’re thinking about therapy — and entirely reasonably so. Therapy is an investment of time, money and courage; it’s right that you should know what you’re stepping into. At the same time, it’s a question any honest therapist answers with “it depends” — and then explains what it depends on.

This piece is that explanation. We’ll look at what research says about the length of therapy (there is a surprisingly precise science on this), why some things need a handful of sessions and others a few years, why there is no miracle shortcut despite all the promises — and how to talk openly about the timeframe with your therapist, so that you’re never left hanging in uncertainty.

No marketing, no scaremongering. Just honestly.

What the length actually depends on

“It depends” isn’t an evasion — it’s a precise answer, because at least three things affect how long therapy takes.

The goal. “I’d like to stop falling apart when I speak in public” and “I’d like to understand why I disappear in every relationship” are two very different projects. The first is bounded and concrete — it can be worked with in a focused way. The second reaches into patterns that took decades to form — and it’s only honest to say that they won’t be worked through in six weeks.

Depth. Some difficulties are like a branch on the surface of the water: visible, accessible, quickly shifted. Others are like a root: the symptom that brings you in (insomnia, irritability, anxiety) is often only the most visible part of an older story. How deep you go is your choice — and both are legitimate. You can sort out the symptom and finish; or you can take the symptom as a doorway and explore what stands behind it.

Pace. Everyone has their own rhythm of opening up. One person says things at the third session that they’ve never told anyone; another needs six months before they bring what really matters into the room. Neither is the “better client” — your pace is part of you, not an obstacle. Therapy that pushed you faster than you can manage wouldn’t be quicker; it would only be shallower.

These three factors also explain why the promise “therapy takes exactly this many sessions” cannot be an honest one: nobody knows in advance what will open up once the space is safe enough. What can be done honestly — and what a good therapist does — is to keep checking where the two of you are on the path, and to adjust the frame to what has emerged.

Short and focused, or long and in-depth

Broadly speaking, therapeutic work stretches between two poles.

Short, focused work (from a few sessions to a few months) makes sense when the difficulty is bounded: a specific decision, an acute crisis, a particular fear, support through a transition. The goal is clear, the work structured, the ending anticipated. For many people that is quite enough — and there is nothing wrong with using therapy as a tool for a concrete thing.

Longer-term, in-depth work (from six months to a few years) is for changing patterns: how you form attachments, how you handle emotions, what you believe about yourself. These patterns have been built over a lifetime, they are woven into your identity and they don’t withdraw on command. Research confirms this: a meta-analysis by Leichsenring and Rabung (2008) in JAMA showed that for complex, long-standing difficulties (including personality patterns), longer-term therapy produces significantly better outcomes than brief forms.

Most real processes are somewhere in between — they start with a symptom and, after a few months, the two of you decide together whether the work is complete or whether the symptom has opened up a more important theme.

It’s also worth knowing that therapy isn’t necessarily one unbroken block. Many people live it in chapters: a period of intensive work, then their own path, and a return a year or three later with a new theme — because life has brought a new transition, or because the earlier work whetted the appetite for something deeper. This isn’t a “relapse” and it doesn’t mean the first chapter didn’t work; it means you’re using therapy as a tool, not as a subscription.

What the research says: the dose-response curve

If all this leaves you wondering whether therapy “works” enough to be worth months of your life — the short answer is yes, and there is an extensive scientific basis for it; I’ve laid it out in detail in my piece on the effectiveness of therapy. Here we’re interested in a narrower question: how long it takes for the effect to appear.

And now to the science, which is unusually concrete on this question. Kenneth Howard and colleagues published a classic study in 1986 on the so-called dose-response relationship in psychotherapy — following the model of pharmacology, they used data from several thousand clients to test how many “doses” of therapy were associated with how much improvement.

They found that improvement follows a characteristic curve: a steep initial rise that gradually levels off. The key points, which later research — including studies of tens of thousands of clients in everyday practice (Hansen and colleagues, 2002) — has confirmed and extended:

• Improvement begins quickly. Some people feel a shift after the very first sessions — the step itself contributes to this: the distress has been given a space, a name and someone to say it to.
• Roughly half of people make noticeable progress after around 8 to 13 sessions. That’s an accessible summary of Howard’s figures — which means half also need more.
• The curve flattens. Every further session adds something, but the biggest leaps happen in the first months. That isn’t a reason to stop — but it is why the nature of the work changes over time: from fire-fighting to building.
• Different things move at different speeds. Kopta and colleagues (1994) showed that acute symptoms (low mood, anxiousness) respond relatively quickly, chronic difficulties more slowly, and deeply rooted personality patterns most slowly of all — for those, even 50 sessions is often not too many.

It’s also important to understand what “noticeable improvement” means in these studies: not perfection and not the absence of all difficulties, but a measurable shift that matters in life — fewer symptoms, better functioning, more room for yourself. For three quarters of people, Howard’s data suggested roughly six months of weekly sessions. These are group averages, not predictions for you — but they give an honest frame for your expectations.

In short: the research doesn’t say “therapy lasts forever”. It says something more useful — most people feel significant relief within the first few months of regular work, while deeper changes take longer. Which is exactly what you’d expect of any serious learning.

Why there is no shortcut (and why that’s actually good news)

“Can’t it be faster?” An understandable question — and the answer is instructive: it can’t, because change in therapy isn’t information, it’s experience. Two things simply take time.

The relationship. Therapy works through trust — research consistently shows that the quality of the therapeutic relationship is one of the strongest predictors of outcome (I’ve written about this in my piece on the therapeutic relationship). And trust can’t be accelerated by willpower: it is built through repeated experiences that this space is safe, that this person doesn’t judge you, that even the hardest things may be said. Only in such a relationship do the themes that genuinely shift things open up.

The brain. The patterns you’re changing aren’t just “thoughts” — they are consolidated neural connections built over years. Restructuring them follows the laws of neuroplasticity: a new connection is consolidated only by repeating the new experience, not by a one-off insight. That’s why change happens across weeks and months of repetition — in the room and between sessions. I’ve explained how conversation literally changes the brain in my piece on neuroplasticity and therapy.

The good news in this: slowness isn’t a fault in the system but a sign that something real is changing. What is built slowly also stays — in research, the effects of therapy are generally maintained after it ends, which is a crucial difference from solutions that work only for as long as you keep using them.

This also makes it clear why I’m wary of anything advertised as a shortcut: “eliminate anxiety in one weekend”, “reprogram your subconscious in five steps”. An intense experience can be powerful — but without repetition and without a relationship that holds the new experience over time, it usually fades. What promises to skip the process most often skips the result as well.

Rhythm: why we usually meet weekly

Alongside duration, rhythm matters too. The established practice — one session a week — is no accident. A week is short enough that the thread between sessions doesn’t slacken and the process keeps its continuity, and long enough that you have time to carry the new experience into your life: to notice the pattern, to try a different response, to bring back what happened.

A similar consideration lies behind the length of a session. The classic therapy hour lasts around 50 minutes — long enough for the conversation to really open and safely close again, and short enough for both people’s attention to stay focused. Longer formats (90 minutes, for instance) make sense with couples, families and particular forms of work, where more people or more layers need to be heard at once.

Less frequent sessions (fortnightly) make sense in later phases, when the process is already standing and the work is more about maintenance and independence. At the beginning, though, too sparse a rhythm often means each session starts over with “what happened in between” — and the process gains depth more slowly. If a weekly rhythm is financially too demanding, that is a legitimate topic for an open conversation with your therapist, not a reason to quietly withdraw.

What speeds the process up and what draws it out

Although there is no shortcut, the length isn’t entirely outside your influence. A few things reliably support the process:

• Regularity. Continuity is the fuel of the process. Every long break means part of the energy goes into re-establishing the thread.
• Work between sessions. An hour a week is a percentage of your time; change happens in the other 99 per cent. Observing your reactions, trying out something new, reflecting after a session — all of it multiplies the effect. I’ve devoted a whole piece to what happens between sessions.
• Openness — including about therapy itself. The themes that eat up the most time are the ones you carry into the room but don’t say out loud. Including “I didn’t feel like coming today” and “what you said last time stung”. Those very sentences are often what deepens the process most.

And what draws it out? Besides the obvious (irregular attendance, avoiding painful themes), mainly quiet leaving: when instead of talking about their doubts, a person simply stops coming. Doubt about therapy isn’t an obstacle to the process — it’s material for it. A therapist you tell that you can’t see any progress has something to work with; a therapist you vanish on has nothing.

How to talk to your therapist about the timeframe

The most important piece of advice in this article: the length of therapy isn’t a secret the therapist keeps — it’s a matter of open agreement. A few questions you can (and are entitled to) ask at any time:

• “Given what I’ve told you — what scope of work do you have in mind?” An honest answer will be an approximation, not a promise.
• “How will we know we’re making progress?” A good therapist is glad to stop and review the path with you. What counts as progress (and what is easy to overlook) is something I’ve described in my piece on the signs that therapy is working.
• “What if I want to finish?” You can end therapy at any time — but it’s good if the ending is an agreement rather than an escape. I write about when and how in my piece on ending therapy.

Money is a legitimate topic too. Therapy is an expense and there is nothing wrong with taking it into account when deciding on rhythm and duration — the only mistake is staying silent about it and choosing to disappear instead of talking. We therapists are used to these conversations; together it’s often possible to find a way that is sustainable for both sides.

Occasional joint reviews of the process — “where are we, where are we going, what else do you need” — are a sign of good work. Therapy that can’t be talked about within therapy isn’t good therapy.

How it works with me

I work as a therapist in training in marriage and family therapy, under regular supervision. With me the length isn’t set in advance: we begin with an introductory session, and then we agree on the path as we go — according to your goal, your pace and what opens up in the process. Some people come for support during a bounded period, others stay longer because the work takes them deeper. Both are right; what matters to me is only that we talk about it openly and that you never stay in the process out of sheer inertia.

With couples and families the logic is similar, except that several nervous systems meet in the room at once — which is why the first shifts sometimes happen faster (the mere fact that a conversation is happening again releases a great deal), while deeper changes in the patterns between two or more people need their time just as they do with an individual.

You’ll find the forms of work and how it unfolds on the Services page. And if what has been putting you off therapy is precisely the uncertainty about how long it takes, let this stay with you: “how long will it take” is a perfectly legitimate first question — and any good therapist will be glad to answer it truthfully. It depends. And then — just like this piece — they’ll calmly and concretely explain what it depends on.
