Kernels of Truth or Distorted Perceptions: Self and Observer Ratings of Social Anxiety and Performance

This study compared self and observer ratings of social performance and anxiety among individuals with social anxiety disorder, nonclinical controls, and participants with dysthymia serving as clinical controls. The purpose was to elucidate whether self-perceptions of individuals with social anxiety disorder reflect observable performance and anxiety differences, negative self-perceptions, or an interaction of the two. Participants engaged in three role-played interactions, and self and observer ratings of performance and anxiety were obtained. In general, self-ratings of anxiety and performance were more negative (greater anxiety and poorer performance) than were observer ratings. Interactions of rating source and diagnosis indicated the discrepancy between self and observer ratings of both anxiety and performance was significantly greater among participants with social anxiety disorder. Observers, however, generally noted differences across the groups in both anxiety and performance. The discrepancies between self and observer ratings of anxiety were related to negative evaluation fears and negative thought patterns, while performance discrepancies were related to negative thought patterns. Treatment implications are discussed

Analogue Observational Methods in the Assessment of Social Functioning in Adults

This article provides a clinically oriented overview of analogue observational methods used in the assessment of problematic social functioning, specifically skill deficits and social anxiety. This article emphasizes role-play assessment methods, the predominant method used in clinical settings. An examination of the psychometric characteristics of analogue assessment methods is presented, followed by a review of procedural and structural considerations that may impact the quality of assessment data. Of special concern are the potential impacts of instructional variables, structured versus ideographic role-played situations, confederate characteristics and behavior, molar and molecular levels of assessment, self-ratings versus clinician ratings of functioning, and physical attractiveness. Finally, published and empirically evaluated analogue observation tests are critically reviewed with an emphasis on features that may impact their utility in clinical practice

Effects of a Transdiagnostic Group Treatment for Anxiety on Secondary Depression

Researchers have recently explored transdiagnostic anxiety treatments based on models of anxiety emphasizing a single common pathway across diagnostic categories. Results from a previous study (Norton and Hope, in press) indicated that a transdiagnostic approach was effective for both targeted and untargeted anxiety disorders. Consistent with the tripartite model, the transdiagnostic treatment should also influence symptoms of a broader pathology such as negative affectivity. This follow-up to Norton and Hope found significant decreases in depressed mood for clients undergoing transdiagnostic treatment for anxiety when compared to wait-list control participants. Although not statistically established, severity of depressive diagnoses seemed to generally decrease across treatment, whereas no change in severity occurred for those not receiving treatment

Aynak : a world-class sediment-hosted copper deposit, Afghanistan

The Aynak copper deposit, located 30 km south of Kabul in Afghanistan, was discovered by Soviet geologists in the 1970s. Extensive exploration undertaken in the area between 1974-80 included several hundred boreholes, seventy trenches and nine exploratory adits. This delineated several large ore bodies and smaller lenses with a total “drill-indicated resource” of 240 Mt at 2.3% Cu (ESCAP, 1995). The mineralisation at Aynak consists of disseminated bornite and chalcopyrite, mainly concentrated in a stratabound orebody in a cyclic succession of metamorphosed dolomites, marls, siltstones and carbonaceous pelites. A model proposes Cu was leached from underlying volcanic rocks and flowed up faults to deposit Cu sulphides into overlying sediments

Generalization of Social Anxiety to Sporting and Athletic Situations: Gender, Sports Involvement, and Parental Pressure

Although researchers have documented that social anxiety may occur in a wide range of interpersonal and performance situations, little attention has been paid to the potential influence of social anxiety on participation in athletics or physical activity. The performance demands of sport and potential social evaluative nature of exercise make it likely that social anxiety would generalize to these situations. Given the physical and psychological benefits of engaging in regular physical activity, avoidance of such activities by socially anxious individuals may have profound health consequences. One-hundred and eighty undergraduate university students completed a battery of standardized social anxiety measures, and a series of 5-point Likert-type questions examining fear and avoidance of sporting and athletic situations. Results indicated that social anxiety and fear of negative evaluation were generally related to social-evaluative fears in sporting or athletic situations, particularly for women. Furthermore, social anxiety was positively correlated with avoidance of individual sporting activities, but not with avoidance of team activities. Further analyses revealed social anxiety did not differ by competition level. However, for men, familial pressure to play sports during high school was associated with higher fear of negative evaluation. Implications for the assessment and treatment of social anxiety disorder are discussed

The Progression of β-amyloid Deposition in the Frontal Cortex of the Aged Canine

Brains from 41 aged canines (≥10 years of age) were examined immunohistochemically to characterize the laminar distribution and age-related progression of β-amyloid (Aβ) in frontal cortex. We classified the Aβ patterns into four distinct types. Type I was characterized by small, faint deposits of Aβ in deep cortical layers. Type II consisted of diffuse deposits of Aβ mainly in layers V and VI. Type III had both dense plaques in superficial layers, and diffuse deposits in deep layers. Finally, Type IV had solely dense plaques throughout all layers of cortex. We compared the Aβ distribution pattern between the Old canines (10–15 years, n=22) and the Very Old canines (\u3e15 years, n=19). The Old group primarily had negative staining, or Type I and Type II patterns of amyloid deposition (73%). Conversely, the Very Old group had predominantly Types II, III and IV deposits (89.5%), a difference that was significant (Pβ deposition in canine frontal cortex is a progressive age-related process beginning with diffuse deposits in the deep cortical layers followed by the development of deposits in outer layers. In support of this hypothesis, the deeper layer diffuse plaques in the Very Old group of dogs also contain the largest proportion of β-amyloid with an isomerized aspartic acid residue at position 7, indicating that these deposits had been present for some time. We also observed fiber-like Aβ immunoreactivity within regions of diffuse Aβ deposits. These fibers appeared to be degenerating neurites, which were negative for hyperphosphorylated tau. Therefore, these fibers may represent a very early form of neuritic change that precede tau hyperphosphorylation or develop by an alternative pathway
