Worry, the anticipation of future threat, is a common feature of anxiety and mood psychopathology. Considerable research has examined the latent structure of worry to determine whether this construct reflects a dimensional or taxonic structure. Recent taxometric investigations have provided support for a unidimensional structure of worry; however, the results of these studies are limited in tha...

Two classification systems are now at the forefront of clinical psychiatric research: (1) Diagnostic and Statistical Manual, Fifth Edition and (2) the National Institutes of Mental Health Research Domain Criteria. Herein, we propose that these two classification systems are complementary rather than mutually exclusive, and when combined provide important information for understanding aspects of...

Interpretations of negative, positive, and ambiguous situations were examined in individuals with generalized anxiety disorder (GAD), other anxiety disorders (ANX), and no psychiatric condition (CTRL). Additionally, relationships between specific beliefs about uncertainty (Uncertainty Has Negative Behavioral and Self-Referent Implications [IUS-NI], and Uncertainty Is Unfair and Spoils Everythin...

Information processing bias was evaluated in a sample of 25 older adults with generalized anxiety disorder (GAD) over the course of 12 weeks of escitalopram pharmacotherapy. Using the CANTAB Affective Go/No Go test, treatment response (as measured by the Hamilton Anxiety Rating Scale, Penn State Worry Questionnaire, and Generalized Anxiety Disorder Severity Scale) was predicted from a bias scor...

The Penn State Worry Questionnaire (PSWQ) was originally designed as a unifactorial measure of pathological trait worry. However, recent studies supported a two-factor solution with positively worded items loading on the first factor and reverse-scored items loading on a second factor. The current study compared this two-factor model to a negative wording method factor solution among college st...

The aim of this study was to evaluate if a population suffering from generalized anxiety disorder could benefit from an Internet based self-help treatment guided via email contact with a therapist. The treatment was based on established cognitive behavioral principles. It was hypothesized that significant improvements would be found as measured by eight self report questionnaires, absence of a ...

Evidence-based practice has a long history; however, attempts to bridge the gap between science and practice have been only partially effective and much work remains to be done. Part of the problem has been the unilateral approach associated with dissemination of research findings to clinical practitioners. In this special series, Goldfried and colleagues (2014--this issue) suggest a two-way br...

Comparing the efficacy of different treatments in psychiatry is difficult for many reasons, even when they are investigated in "head-to-head" studies. A consensus meeting was, therefore, held to produce best practice guidelines for such studies. This article presents the conclusions of this consensus and illustrates it using published data in the field of antidepressant treatment of generalized...

Chair: Stuart Montgomery, Barbara van Zwieten-Boot somatic symptoms that are characteristic for generalised anxiety. The largely nonspecific autonomic anxiety symptoms have been reduced in importance in DSMIV (AmeriCommittee: J. Angst, D.S. Baldwin, M. Bourin, R. Buller, can Psychiatric Association, 1994) with more weight given D. Hackett, S. Kasper, U. Kern, M. Lader, Y. Lecrubier, to nervous ...
