BACKGROUND The clinician-administered version of the Liebowitz Social Anxiety Scale (LSAS-CA) is a commonly used assessment device for the evaluation of social anxiety disorder and has been shown to have strong psychometric characteristics. Because of its apparently straightforward rating format and potential savings in time and effort, interest in the use(More)
BACKGROUND Despite heightened awareness of the clinical significance of social phobia, information is still lacking about putative subtypes, functional impairment, and treatment-seeking. New epidemiologic data on these topics are presented from the National Comorbidity Survey Replication (NCS-R). METHOD The NCS-R is a nationally representative household(More)
Decision making and risk taking are interrelated processes that are important for daily functioning. The somatic marker hypothesis has provided a conceptual basis for processes involved in risk-taking decision making and has been used to link discrete neural substrates to risk-related behaviors. This investigation examined the hypothesis that the degree of(More)
BACKGROUND The paper describes prevalence, impairments, patterns of co-morbidity and other correlates of DSM-IV social phobia in adolescents and young adults, separating generalized and non-generalized social phobics. METHODS Data are derived from the baseline investigation of the Early Developmental Stages of Psychopathology Study (EDSP), a prospective(More)
BACKGROUND Generalized social phobia (GSP) is characterized by fear of social interactions and sensitivity to disapproval by others. Given the established role of the amygdala as part of a distributed neural system for the processing of emotional cues, we hypothesized that subjects with GSP would exhibit greater amygdala activation in response to harsh(More)
BACKGROUND Several prior studies have found reduced hippocampal volume in victims of psychological trauma with post-traumatic stress disorder (PTSD). We were interested to determine if this finding was evident in women who were victimized by severe sexual abuse in childhood. METHODS In this study, hippocampal volume was measured using quantitative(More)
OBJECTIVE Increased amygdala reactivity during processing of certain types of emotional stimuli (e.g., fear, anger) has been observed in patients with anxiety disorders such as social phobia and posttraumatic stress disorder (PTSD). It is uncertain whether this heightened amygdala reactivity is specific to treatment-seeking patients with anxiety disorders(More)
Interpretation of research on the prevalence and sequelae of childhood trauma has been hindered by the use of assessment instruments with unknown psychometric properties. Thus, we examined the psychometric properties of a new childhood trauma measure, the Childhood Trauma Questionnaire (CTQ). The CTQ has demonstrated strong psychometric properties in(More)
We propose a general hypothesis that integrates affective and cognitive processing with neuroanatomy to explain anxiety pronenes. The premise is that individuals who are prone to anxiety show an altered interoceptive prediction signal, i.e., manifest augmented detection of the difference between the observed and expected body state. As a consequence, the(More)
We review the literature on interoception as it relates to depression and anxiety, with a focus on belief, and alliesthesia. The connection between increased but noisy afferent interoceptive input, self-referential and belief-based states, and top-down modulation of poorly predictive signals is integrated into a neuroanatomical and processing model for(More)
