Evidence and outcome studies
We have listed research studies which provide evidence for the effectiveness of systemic and family therapy. These should be useful for families, and important for family therapists and commissioners. There is a section on contextual studies and measures. We include some papers which critically engage with the question of evidence.

Systematic review is a review of a clearly formulated question that uses systematic and explicit methods to identify, select and critically appraise relevant research, and to collect and analyse data from the studies that are included in the review. Statistical methods (meta-analysis) may or may not be used to analyse and summarise the results of the included studies.
Meta-analysis is a statistical technique that combines the results of individual studies to arrive at one overall measure of the effect of a treatment.
Qualitative metasynthesis is an intentional and coherent approach to analyzing data across qualitative studies.
Content analysis of family therapy research publications is a method which can provide an overview of what has been researched.

SCORE-15 Index of Family Functioning and Change: SCORE is a self-report outcome measure designed to be sensitive to the kinds of changes in family relationships that systemic family and couples therapists see as indications of useful therapeutic change. It is intended to be serviceable in everyday practice; short, acceptable to clients and usable across the full range of our work - the full range of presenting problems, the clientele, and the formats of work: including individual, couple, family and multi-family groups. It is free to use. For more information visit AFT page on SCORE: http://www.aft.org.uk/view/score.html.
