Attentional bias toward negative social cues is thought to serve an etiological and/or maintaining role in social anxiety disorder (SAD). The current study tested whether training patients to disengage from negative social cues may ameliorate social anxiety in patients (N = 36) with a primary diagnosis of generalized SAD. Patients were randomly assigned to either an attention training condition (n = 18), in which patients completed a modified dot-probe task designed to facilitate attentional disengagement from disgusted faces, or a control dot-probe task condition (n = 18). As predicted, patients in the attention training condition exhibited significantly greater reductions in social anxiety and trait anxiety, compared with patients in the control condition. At termination, 72% of patients in the active treatment condition, relative to 11% of patients in the control condition, no longer met Diagnostic and Statistical Manual of Mental Disorders (4th ed.) criteria for SAD. At 4-month follow-up, patients in the attention training condition continued to maintain their clinical improvement, and diagnostic differences across conditions were also maintained. Results support attention-based models of anxiety and suggest that attention training is a promising alternative or complementary intervention.
The aim of this study was to investigate reward circuitry responses in autism during reward anticipation and outcomes for monetary and social rewards. During monetary anticipation, participants with autism spectrum disorders (ASDs) showed hypoactivation in right nucleus accumbens and hyperactivation in right hippocampus, whereas during monetary outcomes, participants with ASDs showed hyperactivation in left midfrontal and anterior cingulate gyrus. Groups did not differ in nucleus accumbens responses to faces. The ASD group demonstrated hyperactivation in bilateral amygdala during face anticipation that predicted social symptom severity and in bilateral insular cortex during face outcomes. These results add to the growing body of evidence that autism is characterized by altered functioning of reward circuitry. Additionally, atypical amygdala activation during the processing of social rewards may contribute to the development or expression of autistic features.
In order to examine race-ethnic differences in the lifetime prevalence rates of common anxiety disorders, we examined data from the Collaborative Psychiatric Epidemiology Studies (CPES). The samples included 6,870 White Americans, 4,598 African Americans, 3,615 Hispanic Americans, and 1,628 Asian Americans. White Americans were more likely to be diagnosed with social anxiety disorder, generalized anxiety disorder, and panic disorder than African Americans, Hispanic Americans, and Asian Americans. African Americans more frequently met criteria for post-traumatic stress disorder than White Americans, Hispanic Americans and Asian Americans. Asian Americans were also less likely to meet the diagnoses for generalized anxiety disorder and post-traumatic stress disorder than Hispanic Americans, and were less likely to receive social anxiety disorder, generalized anxiety disorder, panic disorder, and post-traumatic stress disorder diagnoses than White Americans. The results suggest that race and ethnicity need to be considered when assigning an anxiety disorder diagnosis, and possible reasons for the observed differences in prevalence rates between racial groups are discussed.
Anxiety is one of the most common clinical problems among children, adolescents, and adults with autism spectrum disorder (ASD), yet we know little about its etiology in the context of ASD. We posit that emotion regulation (ER) impairments are a risk factor for anxiety in ASD. Specifically, we propose that one reason why anxiety disorders are so frequently comorbid with ASD is because ER impairments are ubiquitous to ASD, stemming from socio-cognitive, physiological, and neurological processes related to impaired cognitive control, regulatory processes, and arousal. In this review, we offer a developmental model of how ER impairments may arise in ASD, and when (moderating influences) and how (meditational mechanisms) they result in anxiety.
Rural communities face significant challenges regarding the adequate availability of diagnostic-, treatment-, and support-services for individuals with autism spectrum disorder (ASD). Specifically, a variety of factors, including geographic distance between families and service providers, low reliance on health care professionals, and cultural characteristics, contribute to the diminished availability and utilization of services. Together, these factors lead to risks for delayed ASD screening and diagnosis, yielding lower educational and functional outcomes. The purpose of this review is to outline the specific diagnosis and treatment barriers that affect individuals with ASD and their families in rural settings. Telehealth feasibility and efficacy research is also reviewed, suggesting that telecommunication services may offer an inroad for addressing the specific service barriers faced by rural communities. Together, the current review identifies specific needs for both research and support services that address the specific access barriers characteristic of rural settings.
