Ambulatory mental health liaison research: a review and preview.

Mental health liaison in primary care is a complex technology requiring scientific study and validation if we are to know when, where, and how to utilize it. Earlier studies have raised as many questions as they have resolved. Recommendations for future research are presented in relation to such issues as: How should mental health consultation/liaison be defined? How should consultation/liaison studies be prioritized? What aspects of consultation/liaison should be studied? What methodologies are appropriate?
