Effectiveness of an empirically supported treatment for social phobia in the field

This study examined the effectiveness of individual exposure combined with cognitive restructuring for social phobia in a clinical setting as well as the influence of sample restriction criteria on the effect size. Participants were 217 unselected patients with a primary diagnosis of social phobia who were treated by 57 therapists in four outpatient clinics of the Christoph-Dornier-Foundation of Clinical Psychology in Germany. Results 6 weeks after the end of therapy showed highly significant reductions in social phobic fears and avoidance as well as in general anxiety and symptoms of depression. However, patients who dropped out during therapy reported a significantly higher degree of depression. Results did not differ between the four outpatient clinics and are comparable with the average effect-sizes reported by meta-analytic studies of controlled efficacy research, using selected patients. Also, restricting the sample according to the selection criteria often applied in research settings did not result in higher effect sizes for the applied outcome measures. We conclude that individual cognitive behavioural therapy for social phobia can be transported from research settings to the field of mental health.     

Psychosocial treatments for social phobia

Increasing recognition of the prevalence and impairment associated with social phobia has spurred the development of effective psychosocial treatments for this disorder. Exposure-based interventions have the most empirical support. This article applies the tripartite model of anxiety to social phobia, describes state-of-the-art psychosocial treatments, and highlights studies on the comparative and combined efficacy of psychological and pharmacologic treatments. Clinical issues related to treatment implementation, limitations of extant psychosocial interventions, and suggestions for future research are also discussed.     

Screening for ADHD in an adult social phobia sample

Objective: Recent studies have suggested a link between a primary anxiety disorder and ADHD. Method: A total of 39 participants with a primary diagnosis of social phobia were compared with 178 patients with ADHD and 88 patients with other psychiatric disorders on measures for childhood and adult ADHD (the Wender Utah Rating Scale and the Adult ADHD Self-Report Scale). Results: Childhood symptoms of ADHD were reported by 7.8% of the social phobia participants, and 5.1% scored within the range of adult ADHD. The social phobia group reported significantly fewer ADHD symptoms than both of the comparison groups, who frequently reported social anxiety. Conclusion: Participants with social phobia recruited from the general population are less likely to suffer from ADHD. In contrast, patients with ADHD and patients with other psychiatric disorders appear to be likely to suffer from social anxiety.     

Memory for facial expressions in social phobia

Memory biases toward threat have been documented in several anxiety disorders, but contradictory findings have recently been reported in social phobics' recognition of facial expressions. The present study examined recognition memory in clients with social phobia, in an effort to clarify previous inconsistent results. Just before giving a speech to a live audience, social phobia clients and normal controls viewed photographs of people with reassuring and threatening facial expressions. The stimuli were later presented again alongside photographs of the same person with a different facial expression, and participants chose which face they had seen before. Individuals with social phobia were less accurate at recognizing previously seen photographs than controls, apparently due to state anxiety. In contrast, social phobics did not show a memory bias toward threatening facial expressions. Theoretical and treatment implications are discussed.     

Interpretations for anxiety symptoms in social phobia

This study explored the ways in which people interpret visible physical symptoms of anxiety. A group of participants with social phobia (SP) and a nonclinical control (NCC) group completed either the Actor version or the Observer version of the Symptom Interpretation Scale (SIS), designed for the purposes of this study. The SIS asks participants to rate the extent to which each of eight interpretations is a likely explanation for a number of visible symptoms of anxiety. On the Actor version of the SIS, participants are asked to judge how their own anxiety symptoms are interpreted by others. On the Observer version of the SIS, participants are asked how they typically interpret anxiety symptoms that they notice in others. When participants were asked about anxiety symptoms that they themselves exhibit, people with social phobia were more likely than nonclinical controls to think that others interpreted these symptoms as being indicative of intense anxiety or a psychiatric condition and were less likely to think that others interpreted these symptoms as being indicative of a normal physical state. Data also suggested that people with social phobia have a more flexible cognitive style when asked to interpret anxiety symptoms exhibited by others than when asked about how others view their own anxiety symptoms. These findings are discussed in the context of recent psychological models of social anxiety and social phobia.     

Effectiveness of cognitive behavioural group therapy for social phobia in a community clinic: a benchmarking study

This study used a benchmarking strategy to investigate the transportability of cognitive behavioural group therapy (CBGT) for social phobia to a community mental health clinic. The influence of common exclusion criteria on effect sizes was also examined. Patients (N=153) attended seven 4-h sessions of CBGT, which resulted in significant reductions in symptoms of social anxiety and depression. Effect sizes compared favourably to previous efficacy and effectiveness studies of both group and individual treatment. More than half of the treatment completers achieved reliable change. One-third achieved clinically significant change (CSC) on the Social Phobia Scale and the Beck Depression Inventory, but fewer achieved CSC on the Social Interaction and Anxiety Scale. Restricting the sample on the basis of depression symptoms, age above or below 50 years, comorbidity, alcohol problems, or student status did not significantly moderate effect sizes for social anxiety. It is concluded that CBGT is effective within community mental health clinics.     

Neurobiology of social phobia

Social phobia is an anxiety disorder that is characterized by excessive fear and/or avoidance of situations in which an individual believes that he or she may be the subject of evaluation or scrutiny while interacting with other people or performing a specific task. This article reviews the available literature on the neurobiology underlying social phobia, including autonomic nervous system effects, neuroimaging findings, pharmacologic challenge studies, and neuroendocrine responsivity and function. Overall, such studies have found few consistently demonstrable differences in neurobiology between patients with social phobia and healthy controls, but further investigations are needed.     

Cognitive features of social phobia

New cognitive models of social phobia have been developed based, in part, on a growing number of studies suggesting that people with social phobia process information related to social threat differently than people who are not socially anxious and, in some cases, differently than individuals with other anxiety disorders. In addition to providing an overview of recent models of social phobia, this paper reviews the research literature to date on the following aspects of cognition in social phobia: attention, memory, attributions and appraisals, imagery and perspective, and perfectionism.     

Group cohesion in cognitive-behavioral group therapy for social phobia

Cognitive-behavior therapy (CBT) for Social Phobia is effective in both group and individual formats. However, the impact of group processes on treatment efficacy remains relatively unexplored. In this study we examined group cohesion ratings made by individuals at the midpoint and endpoint of CBT groups for social phobia. Symptom measures were also completed at the beginning and end of treatment. We found that cohesion ratings significantly increased over the course of the group and were associated with improvement over time in social anxiety symptoms, as well as improvement on measures of general anxiety, depression, and functional impairment. In conclusion, findings are consistent with the idea that changes in group cohesion are related to social anxiety symptom reduction and, therefore, speak to the importance of nonspecific therapeutic factors in treatment outcome.     

Phenomenal characteristics of autobiographical memories for social and non-social events in social phobia

Previous studies failed to show clear differences between people with social phobia and non-anxious individuals regarding the specificity and affective intensity of their autobiographical memories for social events. However, these studies did not assess the subjective experience associated with remembering. In this study, people with social phobia and non-anxious control participants recalled social and non-social events, and rated the phenomenal characteristics of their memories. The memories of people with social phobia for social events contained fewer sensorial details but more self-referential information than controls' memories. In addition, people with social phobia remembered social situations from an observer perspective, viewing themselves as if from outside, to a greater extent than controls. By contrast, the two groups did not differ concerning their memories for non-social events. These findings are discussed in relation to cognitive models of social phobia.     

Deficits in perceived social support associated with generalized social phobia

Social phobia is a common anxiety disorder associated with significant impairment in social and occupational functioning. To date, few studies have examined the relationship between social phobia and perceived social support, a construct with important relationships to physical and mental health. The present study examined data from 2 widely used measures of perceived social support administered to 132 individuals with DSM‐IV generalized social phobia. These data were compared with those obtained from a healthy control group and from several clinical and non‐clinical samples reported in the literature. Persons with generalized social phobia scored significantly lower on both measures of social support compared with all other groups. It is suggested that deficits in perceived social support associated with generalized social phobia may play a role in the development of co‐morbid problems and should be explicitly targeted by treatments for social phobia. Low correlations between perceived social support and social anxiety measures suggest that perceived support should be specifically evaluated in this population.

Blushing and physiological arousability in social phobia

Blushing is the most prominent symptom of social phobia, and fear perception of visible anxiety symptoms is an important component of cognitive behavioral models of social phobia. However, it is not clear how physiological and psychological aspects of blushing and other somatic symptoms are linked in this disorder. The authors tested whether social situations trigger different facial blood volume changes (blushing) between social phobic persons with and without primary complaint of blushing and control participants. Thirty social phobic persons. 15 of whom were especially concerned about blushing, and 14 control participants were assessed while watching an embarrassing videotape, holding a conversation, and giving a talk. Only when watching the video did the social phobic persons blush more than controls blushed. Social phobic persons who complained of blushing did not blush more intensely than did social phobic persons without blushing complaints but had higher heart rates, possibly reflecting higher arousability of this subgroup.     

Working memory capacity in generalized social phobia

Research suggests that understanding complex social cues depends on the availability of cognitive resources (e.g., Phillips, Channon, Tunstall, Hedenstrom, & Lyons, 2008). In spite of evidence suggesting that executive control functioning may impact anxiety (e.g., Eysenck, Derakshan, Santos, & Calvo, 2007), relatively few studies have examined working memory in individuals with generalized social phobia. Moreover, few studies have examined the role of threat-relevant content in working memory performance in clinically anxious populations. To this end, the present study assessed working memory capacity (WMC) in individuals with generalized social phobia and nonanxious controls using an operation span task with threat-relevant and neutral stimuli. Results revealed that nonanxious individuals demonstrated better WMC than individuals with generalized social phobia for neutral words but not for social threat words. Individuals with generalized social phobia demonstrated better WMC performance for threat words relative to neutral words. These results suggest that individuals with generalized social phobia may have relatively enhanced working memory performance for salient, socially relevant information. This enhanced working memory capacity for threat-relevant information may be the result of practice with this information in generalized social phobia.
