Symptoms of Specific and Generalized Social Phobia: An Examination of Discriminant Validity and Structural Relations With Mood and Anxiety Symptoms

Current models divide social phobia into specific (SSP) and generalized (GSP) subtypes and suggest strong overlap between GSP and avoidant personality disorder (APD). Meanwhile, other research suggests reclassifying anxiety and mood disorders as fear and distress disorders. To unify these separate lines of research, this study was designed to test the hypothesis that SSP is more related to fear disorders (e.g., panic and phobias), whereas GSP and APD are more related to distress disorders (e.g., depression and generalized anxiety). Confirmatory factor analysis suggested the best-fitting model had symptoms of GSP, APD, and depression loading on one factor, and symptoms of SSP, panic, and specific phobias loading on a second factor. Key components of this model were (a) the inclusion of GAD symptoms reduced model fit and (b) GSP and APD symptoms significantly predicted SSP symptoms; this is consistent with conceptualizations of individuals with both GSP and SSP reporting performance anxiety.     

Changes in Anxiety Control Beliefs Following a Brief CBT Treatment and Their Association With Anxiety Symptom Reduction

Anxiety control beliefs (i.e., beliefs regarding one’s ability to cope with external, fear-inducing threats and internal reactions to those perceived threats) have been found to negatively predict anxiety symptoms in children and adults and to be modifiable by cognitive-behavioral therapy for anxiety disorders. The current study examines whether changes in anxiety control beliefs were seen following a brief, intensive treatment for specific phobias, and whether those changes were associated with improvements in the targeted phobia and comorbid anxiety disorder symptoms. Participants were 135 children and adolescents (M age = 9.01 years, 49% male) who received one-session treatment (OST) with or without parental involvement for their primary specific phobia. Results indicated that self-reported anxiety control beliefs significantly increased following treatment and that these increases significantly predicted reductions in specific phobia severity and symptoms of comorbid anxiety disorders 6 months and 1 year following treatment. Findings illustrate that involvement in a single 3-hour OST was associated with changes in anxiety control beliefs and demonstrate the potential importance of targeting control beliefs in pediatric anxiety treatment.     

Disgust sensitivity, trait anxiety and anxiety disorders symptoms in normal children.

There is evidence to suggest that disgust sensitivity plays a role in the development of small animal fears and phobias. Recently, Phillips, Senior, Fahy, and David (1998) [Phillips, M. L., Senior, C., Fahy, T., & David, A. S. (1998). Disgust: the forgotten emotion of psychiatry. British Journal of Psychiatry, 172, 373-375.] suggested that disgust sensitivity is also involved in various other anxiety-based symptoms (e.g. obsessive-compulsive complaints, social phobia). The present study sought to test this suggestion in a large sample of normal school children (N = 189). Children completed a measure of disgust sensitivity, the trait anxiety version of the Spielberger State-Trait Anxiety Inventory for Children and the Screen for Child Anxiety Related Emotional Disorders, an instrument that measures DSM-defined anxiety disorders symptoms. Disgust sensitivity was indeed found to be correlated with a broad range of anxiety disorders symptoms. However, results also indicated that these correlations were predominantly carried by trait anxiety. That is, when controlling for levels of trait anxiety, only specific phobia symptoms (including animal phobia, blood-injection-injury phobia and situational-environmental phobia) and separation anxiety disorder symptoms were significantly related to disgust sensitivity, although correlations were rather modest. Taken together, these findings cast doubts on the claim that disgust sensitivity is an unique and independent factor that contributes to a broad range of anxiety disorders.     

Relations Among Symptoms of Social Phobia Subtypes, Avoidant Personality Disorder, Panic, and Depression

This study's primary goal was to examine relations between symptoms of specific social phobia (SSP), generalized social phobia (GSP), avoidant personality disorder (APD), and panic and depression. Past research has suggested a single social phobia continuum in which SSP displays less symptom severity than GSP or APD. We found SSP symptoms correlated less strongly with depression but more strongly with panic relative to both GSP and APD symptoms. These findings challenge a unidimensional model of social phobia, suggesting a multidimensional model may be more appropriate. These findings also inform current research aimed at classifying mood and anxiety disorders more broadly by identifying that the different factors of fear versus distress appear to underlie different subtypes of social phobia.     

The post-event processing questionnaire in a clinical sample with social phobia

Post-event processing (PEP) involving rumination about perceived inadequacy in a past social situation has been proposed as an important maintaining factor in social phobia. The three aims of this study were to examine (a) the factor structure and internal reliability of a modified version of the Post-Event Processing Questionnaire [Rachman, S., Grüter-Andrew, J., & Shafran, R. (2000). Post-event processing in social anxiety. Behaviour Research and Therapy, 38, 611-617] in a clinical sample with social phobia (N=117), (b) the associations between PEP and symptoms of anxiety and depression, and (c) the relationship between perspective-taking ('field' and 'observer') and anxiety. Principal axis factor analysis yielded a highly reliable one-factor solution in our clinical sample, which generally replicated Rachman et al.'s findings with a sample of undergraduate students. PEP was most strongly and independently associated with state anxiety when depression, general anxiety and stress were controlled for. Contrary to expectations, PEP was not related to measures of social anxiety. The relationship between perspective-taking and anxiety was more complex than expected. Theoretical implications of these findings are discussed with reference to contemporary cognitive-behavioural models of social phobia.     

The structure of anxiety symptoms among preschoolers.

This study examined whether anxiety symptoms in preschoolers reflect subtypes of anxiety consistent with current diagnostic classification systems, or should be better regarded as representing a single dimension. Parents of a large community sample of preschoolers aged 2.5 to 6.5 years rated the frequency with which their children experienced a wide range of anxiety problems. Exploratory factor analysis indicated four or five factors and it was unclear whether separation anxiety and generalized anxiety represented discrete factors. Results of confirmatory factor analyses indicated a superior fit for a five-correlated-factor model, reflecting areas of social phobia, separation anxiety, generalized anxiety, obsessive-compulsive disorder and fears of physical injury, broadly consistent with DSM-IV diagnostic categories. A high level of covariation was found between factors, which could be explained by a single, higher order model, in which first order factors of anxiety subtypes loaded upon a factor of anxiety in general. No significant differences were found in prevalence of anxiety symptoms across genders. Symptoms of PTSD in this sample were rare.     

Threat perception bias in nonreferred, socially anxious children

Investigated whether socially anxious children display a threat perception bias. A sample of 252 primary school children ages 8 to 13 years were exposed to ambiguous stories of social situations and instructed to find out as quickly as possible whether a story was scary. Furthermore, children were invited to tell how each story would end and to judge how they would feel when actually confronted with that situation. The main results can be summarized as follows. First, socially anxious children displayed lower thresholds for threat perception than control children. In other words, compared with control children, socially anxious children needed to hear fewer sentences of a story before deciding it was scary. Furthermore, socially anxious children more frequently perceived threat while listening to the stories than did control children. Finally, socially anxious children more often interpreted the stories as threatening and displayed higher levels of negative feelings and cognitions in relation to these stories compared with control children. These findings fit nicely in current information-processing theories of childhood anxiety. An additional aim of this study was to investigate the convergent validity of the social phobia scales of 2 recently developed self-report questionnaires for measuring anxiety disorder symptoms in children: the Spence Children's Anxiety Scale (Spence, 1998) and the Screen for Child Anxiety Related Emotional Disorders (Birmaher et al., 1997). Results indicated that the social phobia scale of the Spence Children's Anxiety Scale and the extended social phobia scale of the Screen for Child Anxiety Related Emotional Disorders correlated substantially with a specific measure of social anxiety, the Social Anxiety Scale for Children-Revised.     

Specific Phobia in Youth: Phenomenology and Psychological Characteristics

Sociodemographic and psychological characteristics of 62 youth with animal and natural environment types of specific phobia were examined in a treatment-seeking sample. Differences due to age, sex, ethnicity, family structure, and family socioeconomic status were not found between youth with the two types of specific phobia. Moreover, differences were not obtained between the two groups in the clinical severity of their phobias, the perceived dangerousness of the feared outcomes associated with their phobias, the perceived levels of coping with their phobias, or overall fearfulness. However, differences between youth with the two types of specific phobias were found on somatic/anxious symptoms, depressive symptoms, and life satisfaction. In addition, differences were noted on withdrawn, somatic complaints, anxious/depressed symptoms, and social problems as reported by the mothers of these youngsters. Finally, differences in the percent of co-occurring anxiety disorders between youth with the two types of specific phobia were found. On all of the domains in which differences were found, youth with the natural environment type fared more poorly than those with the animal type. These findings converge with those obtained in treatment studies which indicate that youth with the natural environment type are more difficult to treat than youth with the animal type.     

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.     

Blood-Injection-Injury Phobia and Dog Phobia in Youth: Psychological Characteristics and Associated Features in a Clinical Sample

Blood-Injection-Injury (BII) phobia is a particularly debilitating condition that has been largely ignored in the child literature. The present study examined the clinical phenomenology of BII phobia in 27 youths, relative to 25 youths with dog phobia—one of the most common and well-studied phobia subtypes in youth. Children were compared on measures of phobia severity, functional impairment, comorbidity, threat appraisals (danger expectancies and coping), focus of fear, and physiological responding, as well as vulnerability factors including disgust sensitivity and family history. Children and adolescents with BII phobia had greater diagnostic severity. In addition, they were more likely to have a comorbid diagnosis of a physical health condition, to report more exaggerated danger expectancies, and to report fears that focused more on physical symptoms (e.g., faintness and nausea) in comparison to youth with dog phobia. The present study advances knowledge relating to this poorly understood condition in youth.     

Anxiety symptoms in Japanese and in German children

The purpose of this study was to compare the frequency of anxiety symptoms and their association with gender and age in Japanese and German children using the Spence Children's Anxiety Scale (SCAS). A total of 1837 children (862 from Germany and 975 from Japan) between the age of 8 and 12 years were investigated. Results revealed that German children reported significantly higher symptoms of separation anxiety, social phobia, obsessive compulsive disorder, and generalized anxiety disorder than Japanese children. Conversely, Japanese children reported significantly higher scores on symptoms related to physical injury fear. In both countries, girls scored higher than boys on all the scales of the SCAS. Symptoms of separation anxiety and panic decreased with age, whereas social phobia increased with age. The findings underscore the impact of culture on children's anxiety.     

Cognitive Correlates of Social Phobia Among Children and Adolescents

We examined different cognitive phenomena in relation to social phobia among children (aged 7 to 11) and adolescents (aged 12–16) separately. Fifty socially phobic youths were compared to 30 normal control children on measures of social anxiety, social expectation as well as self- and observer-rated performance during two social tasks involving a same-aged peer. Additionally, a video-mediated recall procedure was conducted immediately following the two behavioral tasks to examine specific types of self-talk. Results indicated that socially phobic youths had lower expectations of their performance and rated their actual performance worse than controls during a social interaction task, but not a read-aloud task. Self-ratings of decreased performance among socially phobic youths were corroborated by blind observers. Although differences in specific types of self-talk were found between the two groups, these findings were generally moderated by age. Furthermore, certain cognitive symptoms associated with the disorder were more commonly found among older socially phobic youths. The current findings highlight the importance of considering developmental factors in the presentation and treatment of social phobia in youths.     

Fear of Anxiety in Fearful Adults: An Analysis of Heterogeneity Among Phobia Types

Fear of anxiety, the fear of developing physiological symptoms associated with anxiety, is investigated in this study and the extent to which fear of anxiety is differentially present in the various subtypes of specific phobias. Participants were 260 undergraduate students divided into those having fears corresponding to one of the specific phobia types and those having no reported fears. Participants completed a variety of measures including the Agoraphobic Cognitions Questionnaire and the Body Sensations Questionnaire. Results indicated fearful participants had more fear of anxiety than non-fearful participants. In addition, non-fearful participants reported significantly less frequent catastrophic cognitions than fearful participants of the situational and other types. Non-fearful control participants also reported less fear of bodily sensations than fearful participants of the animal and other subtypes. This study provides supporting evidence that the phenomenon of fear of anxiety is present in fears similar to specific phobias.     

Interpersonal subtypes in social phobia: diagnostic and treatment implications

Interpersonal assessment may provide a clinically useful way to identify subtypes of social phobia. In this study, we examined evidence for interpersonal subtypes in a sample of 77 socially phobic outpatients. A cluster analysis based on the dimensions of dominance and love on the Inventory of Interpersonal Problems-Circumplex Scales (Alden, Wiggins, & Pincus, 1990) found 2 interpersonal subtypes of socially phobic patients. These subtypes did not differ on pretreatment global symptom severity as measured by the Brief Symptom Inventory (Derogatis, 1993) or diagnostic comorbidity but did exhibit differential responses to outpatient psychotherapy. Overall, friendly-submissive social phobia patients had significantly lower scores on measures of social anxiety and significantly higher scores on measures of well-being and satisfaction at posttreatment than cold-submissive social phobia patients. We discuss the results in terms of interpersonal theory and the clinical relevance of assessment of interpersonal functioning prior to beginning psychotherapy with socially phobic patients.     

Factor structure of the Spanish version of the Spence Children Anxiety Scale (SCAS)

This paper presents the Spanish version of the Spence Children Anxiety Scale (SCAS), a rating scale for children and adolescents assessing anxiety disorders as they appear in the DSM-IV. SCAS scores were subjected to confirmatory factor analyses in a sample of 1671 children 10 to 17 years old. Results supported the proposed structure of six interrelated scales. This structure is completely invariant (except for means) in boys and girls and across age groups. Overall, girls scored slightly higher than boys. The relationship of SCAS scores with the child's age was nonexistent or very low and negative. The least frequent anxiety problems among children and adolescents were panic attacks and agoraphobia. Problems that most frequently presented extreme high scores were obsessive-compulsive disorder and social phobia. It is concluded that the Spanish version of the SCAS can confidently be used in the assessment of anxiety disorders in children.     

Heterogeneity among specific phobia types in DSM-IV

Recently, it has been suggested that situational specific phobias (e.g., phobias of driving, flying, enclosed places) are more closely related to agorophobia than are other specific phobia types. The present study investigated this hypothesis by examining heterogeneity among the four main DSM-IV specific phobia types, particularly with respect to variables believed to be associated with agoraphobia. Using interviews and behavioral testing, 60 patients with specific phobias of animals, heights, blood/injections, or driving were compared with respect to etiology, age of onset, physiological response, predictability of panic attacks, and focus of apprehension. Fifteen patients suffering from panic disorder with agoraphobia served as a comparison group for some measures. Relative to the other specific phobias, driving phobias were most strongly associated with a later age of onset, similar to that of individuals with agoraphobia. Height phobias were also associated with a late age of onset as well as a more internal focus of apprehension, relative to other groups. Finally, individuals in the blood/injection phobia group reported a more internal focus of apprehension than those in other groups and were the only group to report a history of fainting in the phobic situation. Overall, the results did not support the hypothesis that situational phobias are a variant of agoraphobia. In fact, on several of the variables for which groups did differ, individuals with height phobias (a phobia from the natural environment type) showed a pattern most similar to individuals with agoraphobia. The implications of these results for the classification of specific phobias are discussed.     

Cognitive heterogeneity in genetically based prosopagnosia: A family study

Congenital prosopagnosia (CP) is a selective difficulty in recognizing familiar faces that is present from birth. There is mounting evidence for a familial factor in CP, possibly due to a simple autosomal inheritance pattern. However, potential candidate genes remain to be established, and the question whether genetically based CP is a single trait, or a cluster of related subtypes differing in the pattern of impairments to specific components of the face‐processing system, remains unanswered. In addition, since the great majority of so far described cases with CP were adult at the time of investigation, it remains unknown which specific aspects of face processing are impaired in small children with CP. Here we present the first study that specifically addresses these questions by elucidating the specific mechanisms underlying face‐recognition impairments in seven individuals with CP (aged 4–87 years) belonging to four generations of the same family. Our results indicate that genetically based CP is not a single trait but a cluster of related subtypes, since the pattern of impairments to specific components of the face‐processing system varies in individuals belonging to the same family. In addition, we show that the heterogeneity of the cognitive profile in CP with respect to specific aspects of face processing is apparent from early childhood.     

Parenting Stress and Childhood Psychopathology: An Examination of Specificity to Internalizing and Externalizing Symptoms

The purpose of this study was to examine if specificity exists between three factors of parenting stress (i.e., parental distress, parent–child (PC) dysfunctional interactions, and difficult child) and childhood internalizing and externalizing symptoms. The incremental validity of parenting stress beyond parental psychopathology was also examined. The sample was drawn from families of children aged 5–17 (N = 300), who sought treatment for their child from a community mental health clinic. Results indicated that the PC dysfunctional interactions factor showed specificity to internalizing symptoms when controlling for parental psychopathology. Parental distress did not show specificity or incremental validity and the difficult child factor was associated with both internalizing and externalizing symptoms when controlling for parental psychopathology. The influence of age, gender, and ethnicity on these associations is also presented, and findings are discussed in terms of how the results add to understanding the specific relations between parenting stress and child and adolescent symptoms.     

Exposure to Bullying and General Psychopathology: A Prospective,Longitudinal Study

Although there is mounting evidence that the experience of being bullied associates with both internalizing and externalizing symptoms, it is not known yet whether the identified associations are specific to these symptoms, or shared between them. The primary focus of this study is to assess the prospective associations of bullying exposure with both general and specific (i.e., internalizing, externalizing) factors of psychopathology. This study included data from 6,210 children participating in the Avon Longitudinal Study of Parents and Children (ALSPAC). Child bullying was measured by self-report at ages 8 and 10 years. Child psychopathology symptoms were assessed by parent-interview, using the Development and Well-being Assessment (DAWBA) at ages 7 and 13 years. Bullying exposure significantly associated with the general psychopathology factor in early adolescence. In particular, chronically victimized youth exposed to multiple forms of bullying (i.e., both overt and relational) showed higher levels of general psychopathology. Bullying exposure also associated with both internalizing and externalizing factors from the correlated-factors model. However, the effect estimates for these factors decreased considerably in size and dropped to insignificant for the internalizing factor after extracting the shared variance that belongs to the general factor of psychopathology. Using an integrative longitudinal model, we found that higher levels of general psychopathology at age 7 also associated with bullying exposure at age 8 which, in turn, associated with general psychopathology at age 13 through its two-year continuity. Findings suggest that exposure to bullying is a risk factor for a more general vulnerability to psychopathology.
