The review by Teng and colleagues (2013) makes clear that there exist a number of problems in how we currently conceptualize, assess, and treat (or not treat) comorbid disorders. We make a number of assessments and clinical research suggestions that are meant to improve our understanding and treatment of comorbid conditions that likely share important psychological mechanisms. These suggestions involve (a) including individuals with multiple and serious comorbidities in treatment outcome research, (b) implementing assessment of relevant comorbid conditions in clinical research, (c) emphasizing common mechanisms underlying co-occurring problems, and (d) providing integrated treatment for comorbid disorders. The ultimate goal is to increase our ability to provide treatment that is both effective and efficient for individuals with multiple comorbidities.
