ABSTRACT
Treatment Improvement Protocol (TIP) 42 was developed in response to the recognized prevalence of co-occurring disorders (COD) and research showing the failure of treatment informed by either a mental health or addiction model of change (Drake, Mueser, Brunette, & McHugo, 2004; Hendrickson, Schmal, & Ekleberry, 2004). Based on the work of a consensus panel that gathered information from evidence-based treatment research and clinical practice, TIP 42 has the goal of presenting a “state-of-the-art” integrated treatment model. In creating TIP 42, two questions were kept in mind: “What does the clinician need to know?” and “How can information be conveyed in a manner that makes it readily accessible?”(CAST, 2005a, p. 17). This critique examines the success of TIP 42 in addressing these questions.
