Family therapy and the politics of evidence

This article situates family therapy in the politics of evidence-based practice. While there is a wealth of outcome research showing that family therapy works, it remains on the margin of mainstream therapy and mental health practice. Until recently it has been difficult to satisfy 'gold standards' of randomized control research which require manualization and controlled replication by independent investigators. This is because systemic family therapy is language-based, client-directed and focused on relational process rather than step-by-step operational techniques. As a consequence family therapy is an empirically supported treatment unable to join the evidence-based club. The politics here concerns what is 'evidence', who defines it and the limitations of a scientist-practitioner model. Therapy is art and science and its research needs to be grounded in real-life clinical practice. Common factors such as personal hope and resourcefulness and the therapeutic relationship contribute more to change than technique or model. While arguing for a wider definition of science and evidence it is politic to seek evidence-based status for family therapy. Family therapy is a best practice approach for all therapists where systemic wisdom helps to decide what to do with whom when. A systemic-practitioner model is informed by quantitative and qualitative research and holds modern and postmodern perspectives in tension, a stance I call paramodern. Family therapy is both scientific and systemic; it is a science of context, narrative and relationship.
