Trends in the prevalence of social phobia in the United States: a synthetic cohort analysis of changes over four decades.

Previous analysis of data from the U.S. National Comorbidity Survey (NCS) [24] suggested that the lifetime prevalence of social phobia in the community has increased significantly in recent cohorts. Furthermore, a latent class analysis of NCS data [21] revealed two primary classes of persons with social phobia: those with exclusive speaking fears and those with one or more other social-evaluative fears. Social phobia in the other social fear group is more persistent, more impairing, and more highly co-morbid with other DSM-III-R disorders. The current report presents data on whether the cohort effect is a general aspect of social phobia or is specific to one of the NCS social phobia subtypes, and whether the cohort effect varies as a function of socio-demographic characteristics. Data were drawn from the NCS. Social phobia was assessed with a revised version of the Composite International Diagnostic Interview. Retrospective age of onset reports were used to estimate Kaplan-Meier survival curves for first onset of social phobia in each cohort represented in the survey. Comparison of these curves allowed us to make synthetic estimates based on retrospective reports of intercohort trends in lifetime prevalence. The lifetime prevalence of social phobia appears to have increased in recent cohorts. However, this increase does not exist among social phobics with exclusive fears of speaking. The increase is most pronounced among white, educated, and married persons, and it is not explained by increased co-morbidity with other mental disorders. The fact that the cohort effect is more pronounced for social phobia with one or more non-speaking fears is important in that this is generally a more severe form of the disorder with an earlier age of onset than social phobia with pure speaking fears. The fact that the cohort effect is most pronounced among people with social and economic advantage (i.e., white, married, well-educated) is intriguing and raises questions about the etiologic process that warrant further study in future research.

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.

Anxiety in ethnic minority youth. Methodological and conceptual issues and review of the literature.

Although current research has documented a relatively high prevalence of anxiety disorders in American youth, this research has been conducted mainly with nonminority samples. Fair treatment and increasing numbers of ethnic minority persons in the United States require that more should be known about minority youth. However, research with majority youth cannot be safely generalized to minority youth for several reasons, such as potential differences in the manifestation of anxiety, differences in style of response to assessment devices, and different life circumstances. This review is presented in two major sections. First, the authors address definition of terms and fully examine the significance of studying anxiety in ethnic minority youth. Also considered are methodological issues such as sampling and participation biases. Second, the authors review anxiety in ethnic minority children and adolescents in the United States including studies addressing fears, worries, trait anxiety, test anxiety, and anxiety disorders.

Situational panic attacks: impact on distress and impairment among patients with social phobia.

To investigate the impact of situational panic attacks in social phobia, this study examined symptoms of social anxiety and avoidance, dysfunction, and associated psychopathology among individuals with social phobia who experience situational panic attacks, individuals meeting criteria for both social phobia and panic disorder, and individuals with social phobia but no report of panic attacks. One hundred thirty-three persons with a principal diagnosis of social phobia were evaluated. Fifty-seven individuals, who experienced panic attacks exclusively in the context of feared social situations, were compared to 15 individuals with social phobia who also experienced spontaneous panic attacks and met criteria for panic disorder and 61 social phobics who did not experience panic attacks. Compared to social phobics without panic, social phobics with situational panic attacks demonstrated greater fear and avoidance of social situations and higher ratings of somatic anxiety, were more distressed and impaired by their social phobias, and reported higher levels of anxiety sensitivity and hopelessness than social phobics without panic. Additionally, social phobia patients with situational panic but without panic disorder reported greater hopelessness than participants with comorbid panic disorder. In regression analyses, situational panic attacks accounted for significant unique variance beyond that contributed by the presence of comorbid panic disorder. Situational panic attacks are common in social phobia. They are associated with significant and unique disturbances compared either to the absence of panic attacks or to panic attacks in the context of comorbid panic disorder and deserve attention in both research and treatment of social phobia.

Psychometric properties of the Liebowitz Social Anxiety Scale.

BACKGROUND: The present study provides data on the reliability, validity and treatment sensitivity of the Liebowitz Social Anxiety Scale (LSAS), one of the most commonly used clinician-administered scales for the assessment of social phobia. METHOD: Three hundred and eighty-two patients from several studies of the treatment of social phobia were evaluated. An independent assessor administered the LSAS to each patient prior to the initiation of treatment. Patients also completed other measures of social anxiety and avoidance, although the specific measures varied across samples. RESULTS: The LSAS and its subscales were normally distributed and demonstrated excellent internal consistency. The convergent validity of the LSAS was demonstrated via significant correlations with other commonly-used measures of social anxiety and avoidance. These correlations also tended to be larger than correlations with measures of depression, especially after treatment. However, the pattern of correlations of LSAS subscales with one another and with the other measures suggest that the fear subscales and the avoidance subscales may not be sufficiently distinct in clinical samples. The LSAS was also demonstrated to be sensitive to the effects of pharmacological treatments of social phobia over time and in comparison to double-blind pill placebo. CONCLUSION: The LSAS appears to be a reliable, valid and treatment sensitive measure of social phobia. Further study of the LSAS, both in samples with severe social phobia and in community samples, is needed.

Depression, hopelessness, suicidality, and related factors in sexual minority and heterosexual adolescents.

In the present study, the researchers examined factors related to depression, hopelessness, and suicidality in gay, lesbian, and bisexual adolescents, compared with demographically similar heterosexual adolescents. Sexual minority adolescents reported greater depression, hopelessness, and past and present suicidality than did heterosexual adolescents. However, when controlling for other psychosocial predictors of present distress, significant differences between the 2 samples disappeared. For past suicidality scores, the effects of sexual orientation were reduced, but still significant, when accounting for the other predictor variables. These results suggest that environmental factors associated with sexual orientation, which can be targeted and changed through prevention and intervention efforts, play a major role in predicting distress in this population.

Shyness and sociotropy: additive and interactive relations in predicting interpersonal concerns.

Sociotropy (an aspect of interpersonal dependence) and sociability (affiliative need) were examined as moderator variables of the relationship between shyness and interpersonal concerns in two studies. In Study 1, sociotropy, but not sociability, predicted unique variance in three indices of interpersonal concerns through both direct and interactive relations with shyness. An initial analysis in Study 2 showed that sociotropy, but not sociability, was predictive of participants' perceived competence in situations that involved initiation of conversations and assertion. In the second part of Study 2, sociotropy accounted for significant increments in variance when predicting cognitive and affective manifestations of distress related to simulated conversation and assertion situations, while sociability did not. Study 2 results suggest that sociotropy operates primarily in an additive manner with shyness in predicting interpersonal concerns, rather than moderating the relation between shyness and interpersonal concerns. Differences in the results of the two studies and implications for future research are discussed.

Differentiating anxious and depressive self-statements in youth: factor structure of the Negative Affect Self-Statement Questionnaire among youth referred to an anxiety disorders clinic.

Conducted a factor analysis on the items from the Negative Affect Self-Statement Questionnaire (NASSQ; Ronan, Kendall, & Rowe, 1994). This analysis yielded 4 factors (Depressive Self-Statements, Anxiety/Somatic Self-Statements, Negative Affect Self-Statements, and Positive Affect Self-Statements) broadly consistent with both the content-specificity hypothesis (Beck & Clark, 1988) and L. A. Clark and Watson's (1991b) tripartite model of anxiety and depression. The association between children's self-talk and measures of trait anxiety and depression was also examined. Self-statements with content theoretically specific to depression were the best predictors of self-reported depressive symptoms, but the results were less clear for trait anxiety. Overall, these results provide evidence for the discriminability of anxious and depressive self-talk in youth and for the utility of the NASSQ as a cognitive assessment instrument.

Cognitive-behavioral group therapy versus phenelzine in social phobia: long-term outcome.

UNLABELLED: To evaluate the effects of maintenance treatment and durability of gains after treatment discontinuation, responders to either phenelzine (PZ) or cognitive-behavioral group therapy (CBGT) from an acute trial comparing these two treatments as well as pill placebo and a psychotherapy control (educational supportive group therapy) were enrolled into maintenance and treatment-free follow-up phases. EXPERIMENTAL DESIGN: Responders to an acute trial contrasting PZ and CBGT entered a six-month maintenance phase. Patients who continued to respond through the maintenance phase entered a six-month treatment free phase. Patients receiving pill placebo or educational supportive group therapy in the acute trial did not enter the long term study. PRINCIPAL OBSERVATIONS: PZ patients entered maintenance more improved than CBGT patients, and nonrelapsing PZ patients maintained their superior gains throughout the study. Relapse during maintenance did not differ between treatments. However, PZ patients showed a trend toward greater relapse during treatment-free follow-up. There was a greater relapse among patients with generalized social phobia with phenelzine. CONCLUSIONS: PZ and cognitive-behavioral group therapy may differ in their long term effects. The superiority seen with PZ on some measures in the acute study persisted in patients who maintained their gains over the course of maintenance and treatment-free follow-up. However, CBGT may lead to a greater likelihood of maintaining response after treatment has terminated. Replication with larger samples is needed, as is a study of the acute and long-term efficacy of combined PZ and CBGT.

Subtypes of social phobia in adolescents.

Thirty-three social phobic adolescents were asked to name their ten most feared social situations. Two independent judges classified each situation reported by the participants into one of four situational domains: formal speaking/interactions, informal speaking/interactions, observation by others, and assertion. Fifteen participants (45.5%) were assigned a generalized subtype of social phobia because they endorsed at least moderate anxiety in all four situational domains. This subgroup scored higher on self-report measures of anxiety and depression than the rest of the sample. These results provide empirical support for the existence of subtypes of social phobia in adolescents.

Cognitive behavioral group therapy vs phenelzine therapy for social phobia: 12-week outcome.

BACKGROUND: This article presents results of the acute treatment phase of a 2-site study comparing cognitive behavioral group therapy (CBGT) and treatment with the monoamine oxidase inhibitor phenelzine sulfate for social phobia. METHODS: One hundred thirty-three patients from 2 sites received 12 weeks of CBGT, phenelzine therapy, pill placebo administration, or educational-supportive group therapy (an attention-placebo treatment of equal credibility to CBGT). The "allegiance effect," ie, the tendency for treatments to seem most efficacious in settings of similar theoretical orientation and less efficacious in theoretically divergent settings, was also examined by comparing responses to the treatment conditions at both sites: 1 known for pharmacological treatment of anxiety disorders and the other for cognitive behavioral treatment. RESULTS: After 12 weeks, phenelzine therapy and CBGT led to superior response rates and greater change on dimensional measures than did either control condition. However, response to phenelzine therapy was more evident after 6 weeks, and phenelzine therapy was also superior to CBGT after 12 weeks on some measures. There were few differences between sites, suggesting that these treatments can be efficacious at facilities with differing theoretical allegiances. CONCLUSIONS: After 12 weeks, both phenelzine therapy and CBGT were associated with marked positive response. Although phenelzine therapy was superior to CBGT on some measures, both were more efficacious than the control conditions. More extended cognitive behavioral treatment and the combination of modalities may enhance treatment effect.

Factor structure of the Social Interaction Anxiety Scale and the Social Phobia Scale.

In the study of social anxiety, it is common to differentiate between social interaction versus performance anxiety. The Social Interaction Anxiety Scale was designed to assess social interaction anxiety, and the Social Phobia Scale to assess fear of scrutiny by others (Mattick and Clarke, 1989). In common use, these scales are typically administered together and treated as subscales of a larger measure. However, the joint factor structure of these instruments has never been examined; therefore, it is unclear whether or not the items on these scales actually represent distinct aspects of social anxiety. In the present study, a confirmatory factor analysis of the pooled items from the SIAS and SPS failed to adequately fit the data. An exploratory factor analysis yielded three factors: (1) interaction anxiety, (2) anxiety about being observed by others, and (3) fear that others will notice anxiety symptoms. However, hierarchical factor analysis suggested that these factors all load on a single higher-order factor, social anxiety. Relationships of the first-order factors to other measures of social and performance fear and avoidance are examined, and implications of our findings for the assessment of social phobia are discussed.

Assessment of contemporary social phobia verbal report instruments.

The Social Phobia Scale (SPS), the Social Interaction Anxiety Scale (SIAS) and the Social Phobia and Anxiety Inventory (SPAI) were compared to each other and evaluated in patients with social phobia. We examined the relationship of these three contemporary social phobia verbal report instruments with each other, as well as with behavioral and self-report cognitive criteria. As expected, the three social phobia scales were significantly intercorrelated, although they differed in their relationship to the behavioral and cognitive measures. Specifically, the SPS had a significant negative relationship with time spent in a speech behavioral assessment test. The higher the anxiety scores were on the SPS, the less time patients spent giving an impromptu speech in front of a small audience. The SIAS was consistently related to negative and positive self-reported thoughts in speech and conversation behavioral assessment tests. All instruments differentiated patients with speech phobia from those having both generalized social phobia and avoidant personality disorder; on the SPAI and the SIAS, however, distinguished the former group from individuals with generalized social phobia but not without avoidant personality disorder. All three social phobia instruments were sensitive to treatment changes. Results are discussed in terms of the relative utility of each of these measures' total sores and any and their subscales.

Cross-informant agreement in the assessment of social phobia in youth.

In the present study involving children and adolescents with a principal diagnosis of social phobia, we measured parent-child agreement regarding social anxiety symptoms. Additionally, we examined variables related to the severity of the children's social phobia symptoms as reported by children and as rated by clinicians. Examination of cross-informant agreement indicated little difference between mean parent and children ratings of the children's social fears. In contrast, there was a significant difference in parent and children ratings of the children's avoidance, with parents endorsing greater degrees of social avoidance. Children's report of social avoidance was negatively related to scores on a measure of self-presentational concerns (i.e., social desirability). Clinicians' determination of the severity of the children's social phobia was also influenced by the children's self-presentation as well as parent report of social avoidance and children's depression scores. Thus, this differential weighting by the clinician of parent versus child report may be related to the finding that children's self-reported social avoidance was negatively related to their concerns regarding positive self-presentation. Results suggest the need to consider the impact of social desirability when examining clinical characteristics of children and adolescents with social phobia.

A cognitive-behavioral model of anxiety in social phobia.

The current paper presents a model of the experience of anxiety in social/evaluative situations in people with social phobia. The model describes the manner in which people with social phobia perceive and process information related to potential evaluation and the way in which these processes differ between people high and low in social anxiety. It is argued that distortions and biases in the processing of social/evaluative information lead to heightened anxiety in social situations and, in turn, help to maintain social phobia. Potential etiological factors as well as treatment implications are also discussed.

Clients' expectancies and their relationship to pretreatment symptomatology and outcome of cognitive-behavioral group treatment for social phobia.

The present study examined the expectancies of clients with social phobia that they would benefit from cognitive-behavioral group treatment. Lower expectancies for positive outcome were related to greater severity of social phobia, duration of social phobia, and depression. Lower expectancies were also reported by individuals with the generalized subtype of social phobia, but expectancies were not further influenced by the presence of other Axis I disorders. Expectancy ratings did not differ between clients who dropped out of treatment and those who did not, but, after pretreatment severity of social phobia was accounted for, expectancies significantly predicted improvement among treatment completers. Clients' expectancy beliefs may be an important factor to address in the prediction of who will benefit from a cognitive-behavioral treatment, even when that treatment has demonstrated specific efficacy.
