Understanding the Emotional Disorders: A Symptom-Level Approach Based on the IDAS-II [Hardcover]

Understanding the Emotional Disordersis the first manual for how to use the IDAS-II and examines important, replicable symptom dimensions contained within five adjacent diagnostic classes in the DSM-5: depressive disorders, bipolar and related disorders, anxiety disorders, obsessive-compulsive and related disorders, and trauma- and stressor-related disorders.Improving the measurement of symptoms of emotional disorders has been an important goal of mental health research. In direct response to this need, the Expanded Version of the Inventory of Depression and Anxiety Symptoms (IDAS-II) was developed to assess symptom dimensions underlying psychological disorders. Unlike other scales that serve as screening instruments used for diagnostic purposes, the IDAS-II is not closely tethered to theDiagnostic and Statistical Manual of Mental Disorders(DSM); rather, its scales cut across DSM boundaries to examine psychopathology in a dimensional rather than a categorical way. Developed by authors David Watson and Michael O'Hara, the IDAS-II has broad implications for our understanding of psychopathology.Understanding the Emotional Disordersis the first manual for how to use the IDAS-II and examines important, replicable symptom dimensions contained within five adjacent diagnostic classes in the DSM-5: depressive disorders, bipolar and related disorders, anxiety disorders, obsessive-compulsive and related disorders, and trauma- and stressor-related disorders. It reviews problems and limitations associated with traditional, diagnosis-based approaches to studying psychopathology and establishes the theoretical and clinical value of analyzing specific types of symptoms within the emotional disorders. It demonstrates that several of these disorders contain multiple symptom dimensions that clearly can be differentiated from one another. Moreover, these symptom dimensions are highly robust and generalizable and can be identified in multiple types of data, inlƒ
