Note: In this video, Dr. Stuart Ablon, Director of the Think:Kids program in the Department of Psychiatry at MGH, describes the general tenets of a model of care called Collaborative Problem Solving, which was originated by Dr. Ross Greene in his book The Explosive Child. In 2008, Dr. Greene was forced to end his tenure as the original Director of the Think:Kids program when the Chief of Psychiatry at MGH, Dr. Jerrold Rosenbaum, demanded that he relinquish his intellectual property to MGH. Dr. Greene refused to do so. Since that time, Dr. Ablon and the Think:Kids program have disseminated a variant of Dr. Greene’s work. In 2013, MGH took successful legal action to prohibit Dr. Greene from referring to the model he originated by the name Collaborative Problem Solving. Dr. Greene now refers to his work as Collaborative & Proactive Solutions, and his new non-profit, Lives in the Balance (www.livesinthebalance.org) provides a vast array of free, web-based resources on his model.
