This article from the APA Monitor on Psychology describes the landscape of primary care integration and how practitioners are trying to incorporate this into their practice. Though the article is from two years ago, it is still relevant, as described by faculty member Dr. Sandy Blount.
In its early days the field of integrated primary care learned the hard way, through multiple program failures, that mental health clinicians need targeted training in working in primary care in order to succeed there. The Certificate Program in Primary Care Behavioral Health at UMass Medical School was created so that people who had finished their graduate work could make the transition to succeeding as primary care behavioral health clinicians. At Antioch, our Major Area of Study in Clinical Health Psychology focuses on preparing students to be successful clinicians and leaders in primary care behavioral health. These students are already fully prepared when they graduate, and their success at getting interesting and important jobs as been excellent.
