A moderate common factors approach is proposed as a synthesis or middle path to integrate common and specific factors in evidence-based approaches to high-risk youth and families. The debate in family therapy between common and specific factors camps is reviewed and followed by suggestions from the literature for synthesis and creative flexibility in manual development. A preliminary integrative model termed Integrative Family and Systems Treatment is offered as one option in developing and testing a moderate common factors approach. Such a model might then be studied in eventual clinical trials with other well-developed evidence-based protocols to further address the common versus specific factor debate. Implications for further research and practice are offered.
