Once someone decides to look for help, a decision they are not prepared for arrives almost immediately: should I come alone, come with my partner, or bring the whole family?
The question looks technical and is not. The choice of format often determines what can be addressed at all. The same difficulty — repeating arguments, say — will look entirely different in individual work than in work with a couple, and both can be right.
In this piece I explain what each format can and cannot do, when each works, and how people most often get the choice wrong. As a marriage and family therapist I work in all three, so I can compare them at first hand.
Individual therapy
What it is. One-to-one work, usually 50 minutes. A space in which you are the only user and where you do not have to protect anyone.
When it works best. When the topic is largely yours: anxiety, insomnia, burnout, self-image, grief, a decision you cannot make, a repeating pattern in relationships. Also when the topic is a relationship but the other person is not ready to come.
Its advantage. Depth and candour. Because there is nobody in the room whom your honesty could wound, you reach things you would not say in front of a partner. That is often the precondition for anything shifting at all.
Its limit. I hear only one version of the story — yours. This is not a flaw as long as we both know it, but it is why individual work on relational topics can sometimes drift into entrenching a single perspective. More on what individual therapy really offers.
Couples therapy
What it is. Work with both partners at once, usually 80 to 90 minutes, because a shorter format is too little for two people.
When it works best. When the difficulty lies in the space between you rather than in one of you: repeating arguments, distance, mistrust after an affair, sexuality, the division of burdens, a decision about children, the question of whether to stay together.
Its advantage. That I see the pattern live. A couple can describe how their argument goes for twenty minutes, or the argument can simply happen in the room — and in three minutes I see who withdraws, who pushes, and where the cycle locks. That cannot be obtained from a narrative.
Its limit. With active violence it is not a suitable format, because a joint session can increase risk. It also works poorly when one person has already decided to leave and comes only to announce it.
The most common myth about this format is that the therapist adjudicates who is right. I do not — I have written separately on what really lies behind repeating arguments.
Family therapy
What it is. Work with several family members at once — parents and children, adult children and parents, siblings. The composition is not fixed and can change during the process.
When it works best. When one member’s distress in fact describes the state of the whole: a teenager who has withdrawn, a child struggling at school, cut-off contact between an adult child and a parent, a family after a separation or during illness.
Its advantage. Redistribution of the load. In families it often happens that one member becomes the carrier of the symptom for everyone — and as long as they remain “the problem”, nothing shifts. Once everyone is in the room, it turns out to be a pattern rather than a culprit. I have written separately on why family therapy is not a search for a culprit.
Its limit. At least minimal willingness from everyone is required. A teenager brought under duress rarely participates — though it is useful to know that a good deal shifts if only the parents come.

Group therapy — the fourth format people overlook
Since the decision usually revolves around three formats, it is worth mentioning a fourth, less common here and extremely suitable for certain topics.
What it is. Work in a group of six to ten people with one or two therapists, usually weekly and over a longer period. Groups can be open, with members changing, or closed, running for a set period with the same composition.
Why it works. Since most of our difficulties are relational, a group offers something individual work cannot: a space in which the pattern shows itself live in front of several people. Someone who always takes the role of caring for others in daily life will take it in the group too — and there it can be addressed at the moment it happens.
A second effect is the relief of shame. Hearing someone describe exactly your secret thought is an experience hard to achieve any other way. This is why groups are often used for topics carrying strong shame.
Who it suits. Relational and social topics, loneliness, self-image, grief, and periods after individual therapy ends. It is less suitable during an acute crisis and with recent traumatic experiences.
A practical advantage. The fee per session is usually considerably lower than for individual work, which matters to many people.
Group work is less widespread here mainly because it is organisationally harder — assembling a group that will function takes time. If it interests you, simply ask your therapist whether they run or know of one.
What research says about the formats
Since choosing a format is a practical decision, it is worth looking at what we know rather than only at what seems plausible.
For partner difficulties, work with the couple is generally more effective than individual work. Reviews of research on couple distress consistently show that joint work produces greater improvement in relationship satisfaction than individual treatment of one partner. This is not surprising — a pattern arising between two people is most easily changed where it arises.
For children’s and adolescents’ difficulties, systemic work has solid support. Extensive reviews show good effectiveness of family interventions for behavioural difficulties, eating disorders in adolescents, and after substance misuse. For eating disorders in adolescents, family work is in fact a recommended first choice.
For individual conditions, individual work remains the basis. For anxiety, depression and insomnia most research has been conducted on individual formats, which does not mean the relational environment is unimportant — for depression there are good data for couple-based treatment too, where the relationship is part of what maintains it.
With partner violence, joint treatment is risky. The professional literature is cautious here: a joint session can increase danger, because what is said continues at home. Where violence is present, the correct path is separate treatment and appropriate protection.
What if the two of you disagree about the format
A very common situation: one wants couples therapy, the other says the first should go alone, because the problem is theirs.
This disagreement is rarely about format. It usually speaks to who feels responsible for the state of things and who feels accused by the suggestion of therapy. “You go” is often not indifference but fear — of being declared the culprit in the room.
What works in practice. First, change the invitation. “I’d like us to go, because I don’t know how to talk to you any more, and that’s ours, not yours” is a different thing entirely from “we need help because you can’t communicate.” Second, propose a single session with no commitment onwards — many people are stopped by the image of a long process, not by an introductory conversation. Third, let the other choose the therapist. If they choose, the sense that this is your territory disappears.
And if they still do not come: start alone. Systemically this is not the second-best solution but an entirely legitimate route — when one element in a system changes, the relationship has to change too. Quite often the other partner comes later of their own accord, once they see something is moving and that nobody has accused them.
The four most common mistakes in choosing
“The problem is in the relationship, so we both have to come.” Not necessarily. If one is unwilling, individual work with one partner often shifts the dynamic of both — in a system, a change in one element changes the whole. When only one partner wants therapy.
“The child has the problem, so the child should go.” With younger children it is often more effective to work with the parents. A child is the most sensitive element of the system and often the first to show tension that is not theirs.
“First we’ll go together, then separately.” Possible, but not always sensible. Combining formats with the same therapist has its pitfalls — if I learn something in individual work that the other does not know, I am in an impossible position. This needs agreeing in advance.
“I’ll choose the cheapest format.” Understandable, and sometimes expensive. Six months of individual work on a partner conflict can cost more and achieve less than ten joint sessions.
Combining formats
In practice formats often interweave, and it is worth knowing how.
Sequentially. A fairly common course: a couple first has some joint sessions, then one partner continues individually with a different therapist. This arrangement is clean, because the roles do not overlap.
In parallel. Joint sessions with one therapist and individual sessions with another at the same time. This works if it is clear who does what, and if there is no expectation that the therapists exchange information.
Combined with the same therapist. The most delicate variant. When the same therapist sees a couple together and each separately, they can end up knowing something one partner does not. A clear agreement in advance is therefore essential — I work on the rule that I do not hold secrets.
Family sessions in changing composition. In family work it is entirely normal for everyone to come to one session, only the parents to the next, and a parent and one child to the third. Composition is a tool, not a rule.
Common scenarios and what works in them
A few typical situations I encounter, and the format that usually proves right.
“We’ve been arguing about the same thing for three years.” Couples therapy. The pattern is relational and best seen live.
“My partner had an affair.” Usually work with the couple, often with some individual sessions in between. The decision about whether to stay is made more slowly than either would like.
“I don’t know whether to stay in the relationship.” It depends. If the question is genuinely open, joint work. If the decision has in fact been made, individual — joint sessions would be unfair to the other.
“My son has shut himself in his room and won’t talk.” Family work, but preferably starting with the parents alone. A coerced teenager rarely participates, whereas a changed parental stance has an effect even without their attendance.
“My sister and I haven’t spoken for five years.” Family work with adult siblings is less common and often very effective. I have written separately on whether a relationship can still be repaired.
“I can’t sleep and I’m exhausted.” Individual. When it turns out that insomnia is being maintained by tension at home, one or two joint sessions are often added.
How to decide in three questions
- Whose topic is it? If it is largely yours — individual. If it lives in the space between two people — couple. If several people carry it at once — family.
- Who is willing to come? The ideal format the other party will not agree to is not a format. It is always better to start with what is feasible.
- What do you want to achieve? To understand yourself, or to change how you talk to each other? The first is individual work, the second almost always joint.
And quite practically: you do not have to make this decision alone and in advance. An introductory session is partly for exactly this — working out together which format makes sense for your situation. If it turns out that a different format or a different therapist would serve you better, I will tell you.

Not sure which format is right?
We work that out at an introductory session. If it turns out another format or another therapist would suit you better, I will say so.
