Robust Dimensions of Anxiety Sensitivity: Development and Initial Validation of the Anxiety Sensitivity Index-3.

Accumulating evidence suggests that anxiety sensitivity (fear of arousal-related sensations) plays an important role in many clinical conditions, particularly anxiety disorders. Research has increasingly focused on how the basic dimensions of anxiety sensitivity are related to various forms of psychopathology. Such work has been hampered because the original measure--the Anxiety Sensitivity Index (ASI)--was not designed to be multidimensional. Subsequently developed multidimensional measures have unstable factor structures or measure only a subset of the most widely replicated factors. Therefore, the authors developed, via factor analysis of responses from U.S. and Canadian nonclinical participants (n=2,361), an 18-item measure, the ASI-3, which assesses the 3 factors best replicated in previous research: Physical, Cognitive, and Social Concerns. Factorial validity of the ASI-3 was supported by confirmatory factor analyses of 6 replication samples, including nonclinical samples from the United States and Canada, France, Mexico, the Netherlands, and Spain (n=4,494) and a clinical sample from the United States and Canada (n=390). The ASI-3 displayed generally good performance on other indices of reliability and validity, along with evidence of improved psychometric properties over the original ASI.

Attachment in individuals with social anxiety disorder : The relationship among adult attachment styles, social anxiety, and depression

Despite their apparent implications for social functioning, adult attachment styles have never been specifically explored among persons with social anxiety disorder. In the current study, a cluster analysis of the Revised Adult Attachment Scale (N. L. Collins, 1996) revealed that 118 patients with social anxiety were best represented by anxious and secure attachment style clusters. Members of the anxious attachment cluster exhibited more severe social anxiety and avoidance, greater depression, greater impairment, and lower life satisfaction than members of the secure attachment cluster. This pattern was replicated in a separate sample of 56 patients and compared with the pattern found in 36 control participants. Social anxiety mediated the association between attachment insecurity and depression. Findings are discussed in the context of their relevance to the etiology, maintenance, and cognitive-behavioral treatment of social anxiety disorder.

Hope and optimism as related to life satisfaction

This study explored the hope and optimism constructs and their unique variances in predicting life satisfaction. The subscales (Agency and Pathways) of the Adult Hope Scale (Snyder, Harris et al., 1991) and optimism and pessimism as measured by the Life Orientation Test-Revised (LOT-R; Scheier, Carver, & Bridges, 1994) were compared in terms of ability to predict life satisfaction as measured by the domain-specific Quality of Life Inventory (QOLI®; Frisch, 1994; Study 1, N = 331) and the global measure Satisfaction with Life Scale (Diener, Emmons, Larsen, & Griffin, 1985; Study 2, N = 215). The Agency subscale of the Adult Hope Scale was the better predictor of life satisfaction in both studies. The implications of these findings for theory and measurement of hope and optimism are discussed.

An empirical approach to subtype identification in individuals with social phobia

BACKGROUND The present study used cluster analysis procedures to identify empirically subgroups of patients with social phobia in a large clinical sample. METHOD The Liebowitz Social Anxiety Scale (LSAS) was administered to 382 patients from several studies of the treatment of social phobia. LSAS fear ratings were summed into four subscale scores (social interaction, public speaking, observation by others, eating and drinking in public) based on a previous factor analytical study of the LSAS. In order to produce a stable and robust solution, these factor scores were submitted to a two-stage clustering procedure consisting of an agglomerative-hierarchical clustering method followed by an iterative non-hierarchical clustering method. RESULTS Three patient subgroups were identified based on their pattern of feared social situations on the LSAS. These groups were labelled: (1) pervasive social anxiety; (2) moderate social interaction anxiety; and (3) dominant public speaking anxiety. Clusters differed significantly on age and age of social phobia onset, as well as on measures of social anxiety, general anxiety and depressive symptomatology. Clusters also differed in the percentage of assigned patients who met criteria for the generalized subtype of social phobia and avoidant personality disorder. CONCLUSIONS The results provide empirical support for the existence of three subgroups in a clinical sample of individuals with social phobia and contribute to the growing evidence for the heterogeneity of social phobia. Further study of the conceptual, clinical and aetiological significance of these subgroups is needed.

Behavioral assessment of public-speaking anxiety using a modified version of the Social Performance Rating Scale.

The current study aimed to extend the evaluation of the utility of the Social Performance Rating Scale (SPRS) [Behav. Res. Ther. 36 (1998) 995]. We examined the utility of a modified SPRS for the behavioral assessment of public-speaking anxiety among patients with social phobia (n = 49). The videotaped performance of public-speaking fearful patients in a public-speaking task was rated using four of the five SPRS ratings and was compared to global ratings by patients and observers, as well as to self-report and clinician-administered measures of social anxiety. The pattern of correlations with criterion measures of social anxiety provided evidence for the convergent and divergent validity of this modified SPRS for the behavioral assessment of public-speaking anxiety.

Cognitive Behavioral Therapy for Social Anxiety Disorder

Social anxiety disorder, a once neglected disorder (Liebowitz, Gorman, Fyer, & Klein, 1985), has been increasingly recognized as an important clinical problem. This recognition has led to a surge of research, including numerous studies focusing on approaches to treatment. In this article, we briefly describe cognitive-behavioral treatments for social anxiety disorder (also known as social phobia), provide a critical evaluation of their effectiveness, and discuss the characteristics of patients which may influence response to treatment.
