Need-Adapted Treatment: the Scandinavian roots of Open Dialogue

The story of Open Dialogue usually begins in Western Lapland in the 1980s. The philosophical roots, however, go back further — to Turku, Finland, in the 1970s, where the psychiatrist Yrjö Alanen and his colleagues developed an approach they called Need-Adapted Treatment (NAT). The Turku project was one of the first systematic attempts in Western psychiatry to treat psychosis as something that requires a different therapeutic plan for each person, built collaboratively with the patient, family, and team — rather than a uniform protocol applied identically to everyone with the same diagnosis.

The Turku project

Beginning in the late 1960s and formalised through the 1970s and 1980s, Alanen's team at Turku University Hospital reorganised psychiatric services around several principles:

• Therapy meetings with the family began as soon as a person presented with first-episode psychosis
• The treatment team — psychiatrist, psychologist, nurses, social worker — met regularly with the patient and family together
• Every plan was tailored to the specific person, family, and life situation
• Long-term individual psychotherapy was offered to patients who could engage in it
• Antipsychotic medication was used judiciously and integrated with psychosocial care, not treated as the centre of the plan

Over more than two decades, the Turku group reported steadily improving outcomes for first-episode psychosis. By the early 1990s, many of the prognostic markers for severe long-term illness had reduced substantially, and rates of return to functional life were higher than in comparable Finnish regions using more medication-centred approaches.

Five principles of NAT

Alanen articulated five core principles of Need-Adapted Treatment, which still describe the model today:

1. Therapeutic activities are planned and adapted for each patient and their family.
2. The needs of the patient and family are assessed in joint meetings, repeatedly over time.
3. Different therapeutic approaches (medication, individual therapy, family therapy, group therapy, milieu therapy) are integrated and complement each other.
4. Treatment is a continuous process — the team stays with the family over years, not just episodes.
5. The patient and family are partners; the team's task is not to dictate but to construct treatment together.

What's the difference between NAT and Open Dialogue?

Open Dialogue grew out of NAT, and many practitioners use the terms loosely. The differences are subtle:

• NAT emphasises the integration of multiple therapeutic modalities (psychodynamic individual therapy is often a key component).
• Open Dialogue places more emphasis on the network meeting as the primary therapeutic event and on dialogical, polyphonic practice. Long-term individual psychotherapy is less central.
• NAT is the broader, older framework; Open Dialogue is one specific operationalisation of it, developed in a particular region (Western Lapland) by particular people.

Both share the same core philosophy: psychosis is best treated by responsive, network-oriented, individually tailored care that uses medication carefully and treats the family as a partner.

The evidence base

Long-term cohort data from Turku reported by Alanen and colleagues — collected over decades and published in books including Schizophrenia: Its Origins and Need-Adapted Treatment (1997) and a series of papers — showed:

• Reductions in long-term hospital use
• Higher rates of functional recovery
• Lower long-term medication use compared with treatment-as-usual cohorts
• Improved family functioning and reduced family burden

The data are observational, like the Open Dialogue data, and the same caveats apply. NAT has been less widely studied internationally than Open Dialogue, partly because it is harder to operationalise as a discrete protocol — its essence is flexibility, which is hard to manualise.

Why it matters now

Modern early intervention in psychosis programmes — including the RAISE/Coordinated Specialty Care model in the US — share many features with NAT: multidisciplinary teams, family inclusion, individualised care plans, low-dose medication strategies, supported employment and education. The intellectual lineage is direct, even when it is not explicitly acknowledged.

What NAT looks like in practice

A typical NAT-influenced first-episode service will:

• Hold the first family meeting within days of referral
• Build a written, individualised treatment plan with the family in the room
• Re-assess and revise the plan every few months
• Coordinate medication, individual therapy, family work, and vocational support under one team
• Maintain continuity for two to five years rather than handing care off after stabilisation

What it asks of a system

Like Open Dialogue, NAT is hard to deliver in fragmented systems. It requires a team that stays together over years, that has the time to meet families repeatedly, and that can integrate medication, therapy, and social support. The clinical principles are not new — but the organisational commitment they require is.

Where to read more

Yrjö Alanen's 1997 book Schizophrenia: Its Origins and Need-Adapted Treatment is the foundational text. The 2009 collection Psychotherapeutic Approaches to Schizophrenic Psychoses: Past, Present and Future, edited by Alanen, Silver, González de Chávez, and Martindale, places NAT in a wider historical context. For the contemporary American adaptation, the NIMH RAISE / Coordinated Specialty Care materials cover the model now most likely to be available locally.
