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 the Diagnostic 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 Disorders is 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,
including self-ratings, semi-structured interviews, and clinicians'
ratings. Furthermore, individual symptom dimensions often have
strikingly different correlates, such as varying levels of
criterion validity, incremental predictive power, and diagnostic
specificity. Consequently, it is more informative to examine these
specific types of symptoms, rather than the broader disorders. The
book concludes with the development of a more comprehensive,
symptom-based model that subsumes various forms of
psychopathology-including sleep disturbances, eating- and
weight-related problems, personality pathology, psychosis/thought
disorder, and hypochondriasis-beyond the emotional disorders.
