Recognition of irrationality of fear and the diagnosis of social anxiety disorder and specific phobia in adults: Implications for criteria revision in DSM‐5

Background: In DSM‐IV, the diagnosis of social anxiety disorder (SAD) and specific phobia in adults requires that the person recognize that his or her fear of the phobic situation is excessive or unreasonable (criterion C). The DSM‐5 Anxiety Disorders Work Group has proposed replacing this criterion because some patients with clinically significant phobic fears do not recognize the irrationality of their fears. In the present report from the Rhode Island Methods to Improve Diagnostic Assessment and Services project we determined the number of individuals who were not diagnosed with SAD and specific phobia because they did not recognize the excessiveness or irrationality of their fear. Methods: We interviewed 3,000 psychiatric outpatients and 1,800 candidates for bariatric surgery with a modified version of the Structured Clinical Interview for DSM‐IV. In the SAD and specific phobia modules we suspended the skip‐out that curtails the modules if criterion C is not met. Patients who met all DSM‐IV criteria for SAD or specific phobia except criterion C were considered to have “modified” SAD or specific phobia. Results: The lifetime rates of DSM‐IV SAD and specific phobia were 30.5 and 11.8% in psychiatric patients and 11.7 and 10.2% in bariatric surgery candidates, respectively. Less than 1% of the patients in both samples were diagnosed with modified SAD or specific phobia. Conclusion: Few patients were excluded from a phobia diagnosis because of criterion C. We suggest that in DSM‐5 this criterion be eliminated from the SAD and specific phobia criteria sets. Depression and Anxiety, 2010. © 2010 Wiley‐Liss, Inc.     

Social anxiety disorder: questions and answers for the DSM‐V

Background: This review evaluates the DSM‐IV criteria of social anxiety disorder (SAD), with a focus on the generalized specifier and alternative specifiers, the considerable overlap between the DSM‐IV diagnostic criteria for SAD and avoidant personality disorder, and developmental issues. Method: A literature review was conducted, using the validators provided by the DSM‐V Spectrum Study Group. This review presents a number of options and preliminary recommendations to be considered for DSM‐V. Results/Conclusions: Little supporting evidence was found for the current specifier, generalized SAD. Rather, the symptoms of individuals with SAD appear to fall along a continuum of severity based on the number of fears. Available evidence suggested the utility of a specifier indicating a “predominantly performance” variety of SAD. A specifier based on “fear of showing anxiety symptoms” (e.g., blushing) was considered. However, a tendency to show anxiety symptoms is a core fear in SAD, similar to acting or appearing in a certain way. More research is needed before considering subtyping SAD based on core fears. SAD was found to be a valid diagnosis in children and adolescents. Selective mutism could be considered in part as a young child's avoidance response to social fears. Pervasive test anxiety may belong not only to SAD, but also to generalized anxiety disorder. The data are equivocal regarding whether to consider avoidant personality disorder simply a severe form of SAD. Secondary data analyses, field trials, and validity tests are needed to investigate the recommendations and options. Depression and Anxiety, 2010. © 2010 Wiley‐Liss, Inc.     

Secondary social anxiety in hyperkinesias

This is a comparison study that is aimed to investigate and compare the frequency and severity of secondary social anxiety disorder (SAD) in patients with hyperkinesias, which is associated with a significant sense of disfigurement and compromised social interaction. Patients with hemifacial spasm (n = 20), cervical dystonia (n = 20), and essential tremor (n = 20) were evaluated by SCID‐I, Liebowitz Social Anxiety Scale, Hamilton Anxiety and Depression Rating Scales, and Sheehan Disability Scale. The DSM‐IV H criterion excluding social anxiety related to a medical condition was disregarded for the diagnosis of secondary SAD. The control group (n = 60) consisted of matched healthy subjects. The frequency of the diagnosis and severity of symptoms were compared and associations with sociodemographic and clinical factors were explored. There was no difference between three patient groups in terms of the frequency or the severity of secondary SAD. Younger age and depressive symptoms were associated with the severity of secondary SAD, while severity or duration of the movement disorder or social disability was not. This study revealed a high frequency of secondary SAD in hyperkinesias, emphasizing the need for psychiatric assessment, especially for younger and depressed patients, who seem to be at greater risk. © 2007 Movement Disorder Society     

Social anxiety disorder and marijuana use problems: the mediating role of marijuana effect expectancies

Background: Individuals with social anxiety disorder (SAD) appear particularly vulnerable to marijuana‐related problems. Yet, mechanisms underlying this association are unclear. Methods: This study examined the role of marijuana effect expectancies in the relation between SAD and marijuana problems among 107 marijuana users (43.0% female), 26.2% of whom met Diagnostic and Statistical Manual for Mental Disorders—Fourth Edition criteria for SAD. Anxiety and mood disorders were determined during clinical interviews using the Anxiety Disorders Interview Schedule—IV‐L (ADIS‐IV). Results: Analyses (including sex, marijuana use frequency, major depressive disorder, and other anxiety disorders) suggest that SAD was the only disorder significantly associated with past 3‐month marijuana problems. Compared to those without SAD, individuals with SAD were more likely to endorse the following marijuana expectancies: cognitive/behavioral impairment and global negative expectancies. Importantly, these expectancies mediated the relations between SAD status and marijuana problems. Conclusions: These data support the contention that SAD is uniquely related to marijuana problems and provide insight into mechanisms underlying this vulnerability. Depression and Anxiety, 2009.

Subtyping social anxiety disorder in developed and developing countries

Background: Although social anxiety disorder (SAD) is classified in the fourth edition of The Diagnostic and Statistical Manual (DSM‐IV) into generalized and non‐generalized subtypes, community surveys in Western countries find no evidence of disjunctions in the dose–response relationship between number of social fears and outcomes to support this distinction. We aimed to determine whether this holds across a broader set of developed and developing countries, and whether subtyping according to number of performance versus interactional fears would be more useful. Methods: The World Health Organization's World Mental Health Survey Initiative undertook population epidemiological surveys in 11 developing and 9 developed countries, using the Composite International Diagnostic Interview to assess DSM‐IV disorders. Fourteen performance and interactional fears were assessed. Associations between number of social fears in SAD and numerous outcomes (age‐of‐onset, persistence, severity, comorbidity, treatment) were examined. Additional analyses examined associations with number of performance fears versus number of interactional fears. Results: Lifetime social fears are quite common in both developed (15.9%) and developing (14.3%) countries, but lifetime SAD is much more common in the former (6.1%) than latter (2.1%) countries. Among those with SAD, persistence, severity, comorbidity, and treatment have dose–response relationships with number of social fears, with no clear nonlinearity in relationships that would support a distinction between generalized and non‐generalized SAD. The distinction between performance fears and interactional fears is generally not important in predicting these same outcomes. Conclusion: No evidence is found to support subtyping SAD on the basis of either number of social fears or number of performance fears versus number of interactional fears.

Culture and the anxiety disorders: recommendations for DSM‐V

Background: The anxiety disorders specified in the fourth edition, text revision, of The Diagnostic and Statistical Manual (DSM‐IV‐TR) are identified universally in human societies, and also show substantial cultural particularities in prevalence and symptomatology. Possible explanations for the observed epidemiological variability include lack of measurement equivalence, true differences in prevalence, and limited validity or precision of diagnostic criteria. One central question is whether, through inadvertent “over‐specification” of disorders, the post‐DSM‐III nosology has missed related but somewhat different presentations of the same disorder because they do not exactly fit specified criteria sets. This review canvases the mental health literature for evidence of cross‐cultural limitations in DSM‐IV‐TR anxiety disorder criteria. Methods: Searches were conducted of the mental health literature, particularly since 1994, regarding cultural or race/ethnicity‐related factors that might limit the universal applicability of the diagnostic criteria for six anxiety disorders. Results: Possible mismatches between the DSM criteria and the local phenomenology of the disorder in specific cultural contexts were found for three anxiety disorders in particular. These involve the unexpectedness and 10‐minute crescendo criteria in Panic Disorder; the definition of social anxiety and social reference group in Social Anxiety Disorder; and the priority given to psychological symptoms of worry in Generalized Anxiety Disorder. Limited evidence was found throughout, particularly in terms of neurobiological markers, genetic risk factors, treatment response, and other DSM‐V validators that could help clarify the cross‐cultural applicability of criteria. Conclusions: On the basis of the available data, options and preliminary recommendations for DSM‐V are put forth that should be further evaluated and tested.

Clinical differences between early‐ and late‐onset social anxiety disorders

Aim: The aim of this study was to elucidate the clinical differences between early‐ and late‐onset social anxiety disorder (SAD) in the Korean population. Methods: Three hundred and eighty‐seven outpatients diagnosed with SAD participated in this study. Confirmation of SAD diagnosis was based on the Mini International Neuropsychiatric Interview. All subjects completed the Liebowitz Social Anxiety Scale and anxiety‐trait‐related scales such as the Anxiety Sensitivity Index, Retrospective Self‐Report of Inhibition, Trait Form of the State‐Trait Anxiety Inventory, and Beck Depression Inventory. Results: The early‐onset group (n = 209) consisted of subjects aged up to 18 years at the time of onset, whereas the late‐onset group (n = 178) consisted of subjects older than 18 years at the time of onset. Early‐onset SAD patients were more likely to have the generalized subtype and to visit clinics with chief complaints other than social anxiety symptoms. They exhibited more severe symptoms and higher behavioural inhibitions. After adjusting for age and symptom severity, behavioural inhibition was the only significant difference between the two groups. The degree of behavioural inhibitions was associated with earlier onset age. Conclusion: Symptom severity and behavioural inhibitions, especially in social/school situations, were clinical characteristics that differentiated between early‐ and late‐onset SAD.     

Social anxiety disorder in adults who stutter

Background: The nature and prevalence of social anxiety disorder (social phobia (SP)) in people who stutter is uncertain, and DSM‐IV differential diagnosis guidelines make it difficult to classify an adult who stutters (AWS) with SP as it is assumed any social anxiety symptoms will be a consequence of their stuttering. The aim of this study was to determine the spot prevalence of SP in AWS and to investigate differences in social anxiety between AWS and controls who do not stutter. Methods: The study involved a comprehensive assessment of 200 AWS and 200 adults who do not stutter similar in age and sex ratio. Measures included stuttering severity, health status, self‐report measures of social anxiety as well as a structured diagnostic interview for SP for randomly selected sub‐group of 50 from each group. Results: The AWS were found to have significantly raised trait and social anxiety, as well as significantly increased risk of SP in comparison to the controls. Findings indicated a SP spot prevalence of at least 40% in AWS, and for them to be at high risk of having Generalized SP. Conclusions: It is concluded that the DSM‐IV diagnostic guidelines for diagnosing SP in AWS could result in professional confusion and have possible negative mental health ramifications. Implications for the psychological and medical treatment of AWS are discussed. Depression and Anxiety, 2010. © 2010 Wiley‐Liss, Inc.     

Prevalence of anxiety disorders and anxiety subtypes in patients with Parkinson's disease

Anxiety disorders are common in Parkinson's disease (PD), but are not well characterized. This study determined the prevalence and clinical correlates of all DSM‐IV‐TR anxiety disorder diagnoses in a sample of 127 subjects with idiopathic PD who underwent comprehensive assessments administered by a psychiatrist and neurologist. A panel of six psychiatrists with expertise in geriatric psychiatry and/or movement disorders established by consensus all psychiatric diagnoses. Current and lifetime prevalence of at least one anxiety disorder diagnosis was 43% (n = 55) and 49% (n = 63), respectively. Anxiety disorder not otherwise specified, a DSM diagnosis used for anxiety disturbances not meeting criteria for defined subtypes, was the most common diagnosis (30% lifetime prevalence, n = 38). Compared with nonanxious subjects, panic disorder (n = 13) was associated with earlier age of PD onset [50.3 (12.2) vs. 61.0 (13.7) years, P < 0.01], higher rates of motor fluctuations [77% (10/13) vs. 39% (25/64), P = 0.01] and morning dystonia [38% (5/13) vs. 13% (8/62), P < 0.03]. This high prevalence of anxiety disorders, including disturbances often not meeting conventional diagnostic criteria, suggests that anxiety in PD is likely underdiagnosed and undertreated and refined characterization of anxiety disorders in PD is needed. In addition, certain anxiety subtypes may be clinically useful markers associated with disease impact in PD. © 2009 Movement Disorder Society     

Panic attacks as a risk for later psychopathology: results from a nationally representative survey

Background: There is a growing body of literature suggesting that panic attacks without panic disorder are associated with increases in a wide range of psychopathology and impairment. However, the majority of the literature to date has been cross‐sectional. Some longitudinal research supports the view that panic attacks are a nonspecific risk factor for future psychopathology. Using a large nationally representative longitudinal survey of adults, we sought to determine whether panic attacks predict new onset Axis I disorders. Methods: The Alcohol Use Disorder and Associated Disabilities Interview Schedule—DSM‐IV Version was used to make diagnoses of psychiatric disorders in the National Epidemiologic Survey on Alcohol and Related Conditions Waves 1 and 2 (n = 34,653, aged 18 and older, response rate = 70.2%). Incident psychiatric disorders at Wave 2 were compared between people with and without panic attacks at Wave 1. Results: Panic attacks at Wave 1 were significantly associated with increased incidents of generalized anxiety disorder, panic disorder, social phobia, major depression, dysthymia, mania and hypomania, any anxiety disorder, and any mood disorder even after adjusting for sociodemographic variables, Wave 1 Axis I disorders, and Axis II disorders (OR's ranging from 1.62 to 2.77). Conclusions: The presence of panic attacks may be an important indicator of overall psychological distress and the risk of more severe psychopathology in the future.

The natural course of social anxiety disorder among adolescents and young adults

Beesdo‐Baum K, Knappe S, Fehm L, Höfler M, Lieb R, Hofmann SG, Wittchen H‐U. The natural course of social anxiety disorder among adolescents and young adults. Objective: To examine the natural course of social anxiety disorder (SAD) in the community and to explore predictors for adverse long‐term outcomes. Method: A community sample of N = 3021 subjects aged 14–24 was followed‐up over 10 years using the DSM‐IV/M‐CIDI. Persistence of SAD is based on a composite score reflecting the proportion of years affected since onset. Diagnostic stability is the proportion of SAD subjects still affected at follow‐up. Results: SAD reveals considerable persistence with more than half of the years observed since onset spent with symptoms. 56.7% of SAD cases revealed stability with at least symptomatic expressions at follow‐up; 15.5% met SAD threshold criteria again. 15.1% were completely remitted (no SAD symptoms and no other mental disorders during follow‐up). Several clinical features (early onset, generalized subtype, more anxiety cognitions, severe avoidance and impairment, co‐occurring panic) and vulnerability characteristics (parental SAD and depression, behavioural inhibition, harm avoidance) predicted higher SAD persistence and – less impressively – diagnostic stability. Conclusion: A persistent course with a considerable degree of fluctuations in symptom severity is characteristic for SAD. Both consistently meeting full threshold diagnostic criteria and complete remissions are rare. Vulnerability and clinical severity indicators predict poor prognosis and might be helpful markers for intervention needs.

Bipolar Disord 2010: 12: 271–284. © 2010 The Authors.
Journal compilation © 2010 John Wiley & Sons A/S. Objective: To test two hypotheses of psychiatric comorbidity in bipolar disorder (BD): (i) comorbid disorders are independent of BD course, or (ii) comorbid disorders associate with mood. Methods: In the Jorvi Bipolar Study (JoBS), 191 secondary‐care outpatients and inpatients with DSM‐IV bipolar I disorder (BD‐I) or bipolar II disorder (BD‐II) were evaluated with the Structured Clinical Interview for DSM‐IV Disorders, with psychotic screen, plus symptom scales, at intake and at 6 and 18 months. Three evaluations of comorbidity were available for 144 subjects (65 BD‐I, 79 BD‐II; 76.6% of 188 living patients). Structural equation modeling (SEM) was used to examine correlations between mood symptoms and comorbidity. A latent change model (LCM) was used to examine intraindividual changes across time in depressive and anxiety symptoms. Current mood was modeled in terms of current illness phase, Beck Depression Inventory (BDI), Young Mania Rating Scale, and Hamilton Depression Rating Scale; comorbidity in terms of categorical DSM‐IV anxiety disorder diagnosis, Beck Anxiety Inventory (BAI) score, and DSM‐IV‐based scales of substance use and eating disorders. Results: In the SEM, depression and anxiety exhibited strong cross‐sectional and autoregressive correlation; high levels of depression were associated with high concurrent anxiety, both persisting over time. Substance use disorders covaried with manic symptoms (r = 0.16–0.20, p < 0.05), and eating disorders with depressive symptoms (r = 0.15–0.32, p < 0.05). In the LCM, longitudinal intraindividual improvements in BDI were associated with similar BAI improvement (r = 0.42, p < 0.001). Conclusions: Depression and anxiety covary strongly cross‐sectionally and longitudinally in BD. Substance use disorders are moderately associated with manic symptoms, and eating disorders with depressive mood.     

Correlations between the offensive subtype of social anxiety disorder and personality disorders

Aims: Recent studies have revealed the possibility that the offensive subtype of social anxiety disorder (SAD) may no longer be a culture‐bound syndrome; however, detailed clinical pictures have never been reported. This study investigated the differences between the offensive and non‐offensive subtypes of SAD in terms of the background and axis I and II comorbidity. Methods: A total of 139 patients with SAD based on DSM‐IV criteria were studied by conducting a semi‐structured interview including the Structured Clinical Interview for DSM‐IV axis I and II disorders, and the Liebowitz Social Anxiety Scale. Results: Fifty‐two (37%) patients were classified with the offensive subtype. There were no significant differences in most demographic variables and axis I lifetime comorbidity between offensive and non‐offensive subtype patients. On logistic regression analysis, offensive subtype patients showed a more frequent history of parental physical abuse, higher Liebowitz Social Anxiety Scale scores, and more frequently exhibited obsessive–compulsive personality disorders than non‐offensive subtype patients. Conclusion: Yamashita (1977) reported that the majority of offensive subtype patients were doted on by their parents, although current offensive subtype patients are more likely to have had a troubled childhood, show severer forms of SAD, and more frequently exhibit an inflexible personality. This study suggested that the offensive subtype might not be essentially different from the non‐offensive subtype (quantitative rather than qualitative).     

Separation anxiety disorder in OCD

Background: A history of separation anxiety disorder (SAD) is frequently reported by patients with obsessive–compulsive disorder (OCD). The purpose of this study was to determine if there are clinical differences between OCD‐affected individuals with, versus without, a history of SAD. Methods: Using data collected during the OCD Collaborative Genetic Study, we studied 470 adult OCD participants; 80 had a history of SAD, whereas 390 did not. These two groups were compared as to onset and severity of OCD, lifetime prevalence of Axis I disorders, and number of personality disorder traits. Results: OCD participants with a history of SAD were significantly younger than the non‐SAD group (mean, 34.2 versus 42.2 years; P<.001). They had an earlier age of onset of OCD symptoms (mean, 8.0 versus 10.5 years; P<.003) and more severe OCD, as measured by the Yale–Brown Obsessive Compulsive Scale (mean, 27.5 versus 25.0; P<.005). In addition, those with a history of SAD had a significantly greater lifetime prevalence of agoraphobia (odds ratio (OR) = 2.52, 95% confidence interval (CI) = 1.4–4.6, P<.003), panic disorder (OR = 1.84, CI = 1.03–3.3 P<.04), social phobia (OR = 1.69, CI 1.01–2.8, P<.048), after adjusting for age at interview, age at onset of OCD, and OCD severity in logistic regression models. There was a strong relationship between the number of dependent personality disorder traits and SAD (adjusted OR = 1.42, CI = 1.2–1.6, P<.001). Conclusions: A history of SAD is associated with anxiety disorders and dependent personality disorder traits in individuals with OCD.

Screening capacity of the Multidimensional Anxiety Scale for Children (MASC) for DSM-IV anxiety disorders

Background: The Multidimensional Anxiety Scale for Children (MASC) is a widely used self‐report questionnaire for the assessment of anxiety symptoms in children and adolescents. Methods: This study used receiver operating characteristic analyses to investigate the predictive value of the MASC total and scale scores for DSM‐IV anxiety diagnoses in a referred sample. Eight‐ to 18‐year‐olds (n=212) were assessed with the MASC and Anxiety Disorders Interview Schedule for Children (ADIS‐C). Results: The MASC total score did not exceed the threshold for being judged as fair in predicting any ADIS‐C/DSM‐IV anxiety diagnosis. The Separation Anxiety scale and the Physical Symptoms scale predicted Panic Disorder (PAD) and Agoraphobia fairly accurately. The Social Anxiety scale predicted Social Phobia, and the Separation Anxiety scale predicted PAD to a moderate degree. The MASC scale Harm Avoidance did not predict any ADIS‐C/DSM‐IV diagnosis. Conclusions: These results suggest that the MASC may not be a valid screening instrument for DSM‐IV diagnoses. Depression and Anxiety, 2008. © 2008 Wiley‐Liss, Inc.     

The effect of Avoidant Personality Disorder on the persistence of Generalized Social Anxiety Disorder in the general population: results from a longitudinal, nationally representative mental health survey

Background: The primary objective of this study was to prospectively examine the role of Avoidant Personality Disorder (AvPD) as a determinant in the outcome of Generalized Social Anxiety Disorder (GSAD) using Wave 2 of the National Epidemiologic Survey of Alcohol and Related Conditions 3 years later. Method: This study analyzed data from Waves 1 and 2 of the NESARC (n = 34,653). GSAD was operationalized based on the DSM‐IV definitions of this SAD subtype. Results: Logistic regression analyses indicated that AvPD significantly predicted the persistence of GSAD, even after adjusting for a number of important sociodemographic variables and other psychiatric comorbidity. AvPD did not significantly predict outcome in non‐generalized SAD. Conclusions: AvPD can influence the course of GSAD in adulthood. Specific personality dimensions may underlie and explain the similarities between AvPD and GSAD. Self‐criticism could be a shared feature of both AvPD and GSAD and could represent an important psychological marker of poor prognosis in comorbid GSAD and AvPD.

The characteristics of the comorbidity between social anxiety and separation anxiety disorders in adult patients

Abstract

Objective: In the present study, we compared social anxiety disorder (SAD) patients with (n?=?31) and without childhood and adulthood separation anxiety disorder (SeAD) (n?=?50) with respect to suicidal behavior, avoidant personality disorder (AvPD), other anxiety disorders (ADs), and major depression as well as some sociodemographic variables.

Methods: In assessment of patients, we used Structured Clinical Interview for Separation Anxiety Symptoms, childhood and adulthood Separation Anxiety Symptom Inventories, Liebowitz Social Anxiety Scale, The SCID-II Avoidant Personality Disorder Module, Beck Depression Inventory, and Beck Scale for Suicidal Ideation.

Results: SAD patients with SeAD had higher comorbidity rates of AvPD, other lifetime ADs and panic disorder, and current major depression than those without SeAD. The current scores of SAD, depression, and suicide ideation and the mean number of AvPD symptoms were significantly higher in comorbid group compared to pure SAD subjects. The SAD and SeAD scores had significant associations with current depression, suicide ideations, and AvPD. The mean number of AvPD criteria and the current severity of depression were significantly associated with the comorbidity between SAD and SeAD.

Conclusion: Our findings might indicate that the comorbidity of SeAD with SAD may increase the risk of the severity of AvPD and current depression.     

Generalized worry disorder: a review of DSM‐IV generalized anxiety disorder and options for DSM‐V

Background: Generalized anxiety disorder (GAD) has undergone a series of substantial classificatory changes since its first inclusion in DSM‐III. The majority of these revisions have been in response to its poor inter‐rater reliability and concerns that it may lack diagnostic validity. This article provides options for the revision of the DSM‐IV GAD criteria for DSM‐V. Method: First, searches were conducted to identify the evidence that previous DSM Work Groups relied upon when revising the DSM‐III‐R GAD and the overanxious disorder classifications. Second, the literature pertaining to the DSM‐IV criteria for GAD was examined. Conclusions: The review presents a number of options to be considered for DSM‐V. One option is for GAD to be re‐labeled in DSM‐V as generalized worry disorder. This would reflect its hallmark feature. Proposed revisions would result in a disorder that is characterized by excessive anxiety and worry generalized to a number of events or activities for 3 months or more. Worry acts as a cognitive coping strategy that manifests in avoidant behaviors. The reliability and validity of the proposed changes could be investigated in DSM‐V validity tests and field trials.

Potential use of Internet‐based screening for anxiety disorders: a pilot study

Background: The Internet is a widely used resource for obtaining health information. Internet users are able to obtain anonymous information on diagnoses and treatment, seek confirmatory information, and are able to self‐diagnose. We posted a self‐report diagnostic screening questionnaire for DSM‐IV anxiety and mood disorders (MACSCREEN) on our clinic website. Method: Three hundred and two individuals completed the MACSREEN. For those who qualified for a DSM‐IV disorder, self‐report symptom severity measures were completed for the specified disorder: Quick Inventory of Depressive Symptomatology, self‐report, Social Phobia Inventory, GAD‐7, Davidson Trauma Scale, Panic and Agoraphobia Scale, and Yale/Brown Obsessive Compulsive Scale, self‐report. Cutoff scores for each self‐report measure were used to evaluate clinically significant symptom severity. Respondents were also asked to complete a series of questions regarding their use of the Internet for health information. Results: The mean age of the MACSCREEN sample was 35.2 years (±13.9), where the majority (67.2%) were female. The most frequently diagnosed conditions were social phobia (51.0%), major depressive disorder (32.4%), and generalized anxiety disorder (25.5%). Sixty‐five percent of the sample met criteria for at least one disorder. Most respondents reported completing the MACSCREEN, as they were concerned they had an anxiety problem (62.3%). The majority of respondents reported seeking health information concerning specific symptoms they were experiencing (54.6%) and were planning to use the information to seek further assessment (60.3%). Conclusion: Individuals with clinically significant disorder appear to be using the Internet to self‐diagnose and seek additional information.

Social trauma and its association with posttraumatic stress disorder and social anxiety disorder

The key characteristic of a traumatic event as defined by the Diagnostic and Mental Manual of Mental Disorders (DSM) seems to be a threat to life. However, evidence suggests that other types of threats may play a role in the development of PTSD and other disorders such as social anxiety disorder (SAD). One such threat is social trauma, which involves humiliation and rejection in social situations. In this study, we explored whether there were differences in the frequency, type and severity of social trauma endured by individuals with a primary diagnosis of SAD (n = 60) compared to a clinical control group of individuals with a primary diagnosis of obsessive compulsive disorder (OCD, n = 19) and a control group of individuals with no psychiatric disorders (n = 60). The results showed that most participants in this study had experienced social trauma. There were no clear differences in the types of experiences between the groups. However, one third of participants in the SAD group (but none in the other groups) met criteria for PTSD or suffered from clinically significant PTSD symptoms in response to their most significant social trauma. This group of SAD patients described more severe social trauma than other participants. This line of research could have implications for theoretical models of both PTSD and SAD, and for the treatment of individuals with SAD suffering from PTSD after social trauma.
