Abstract
Social anxiety disorder (SAD) is prevalent among university students, yet data on its severity among foreign-born international undergraduate students in Türkiye remains limited. This study aims to determine the prevalence of SAD and its associated factors within this population. A cross-sectional study was conducted using a Google Form survey distributed across various universities from September 17, 2023, to February 1, 2024. The survey comprised two sections: sociodemographic information and 17 items of the Social Phobia Inventory (SPIN), which measures the frequency and intensity of social anxiety symptoms. Data analysis included descriptive statistics and inferential analysis, multiple regression, and binomial logistic regression. Out of 506 participants, 455 were included in the study. Results revealed that 39.1% exhibited no or very mild symptoms of SAD, while 23.7% experienced mild symptoms, 21.3% faced moderate symptoms, and 11.6% and 4.2% presented with severe to very severe symptoms, respectively. Factors such as gender (p < 0.0001), previous academic failures (p = 0.013), family history of mental health issues (p = 0.009), exercise frequency (p < 0.0001), and perceptions of relationships with classmates (p < 0.0001) were significantly associated with SAD. Females showed a higher probability of SAD compared to males (OR = 1.976). Individuals engaging in over 90 minutes of exercise per week were less likely to have SAD (OR = 0.383), and occasional smokers had a lower risk of SAD compared to non-smokers (OR = 0.422). Our study uncovered a notably elevated prevalence of Social Anxiety Disorder (SAD) among foreign-born undergraduate students in Türkiye. Factors such as being female, having a family history of mental illnesses, studying in a stressful environment, experiencing academic failure, and engaging in less frequent exercise were associated with noticeable symptoms of SAD. These findings emphasize the urgent need for heightened efforts in recognizing and addressing SAD within this population.

Abstract
Parental verbal threat (vs. safety) information regarding the social world may impact a child's fear responses, evident in subjective, behavioral, cognitive, and physiological indices of fear. In this study, primary caregivers provided standardized verbal threat or safety information to their child (N = 68, M = 5.27 years; 34 girls) regarding two strangers in the lab. Following this manipulation, children reported fear beliefs for each stranger. Physiological and behavioral reactions were recorded as children engaged with the two strangers (who were blind to their characterization) in a social interaction task. Child attention to the strangers was measured in a visual search task. Parents also reported their own, and their child's, social anxiety symptoms. Children reported more fear for the stranger paired with threat information, but no significant differences were found in observed child fear, attention, or heart rate. Higher social anxiety symptoms on the side of the parents and the children exacerbated the effect of parental verbal threat on observed fear. Our findings reveal a causal influence of parental verbal threat information only for child-reported fear and highlight the need to further refine the conditions under which acquired fear beliefs persist and generalize to behavior/physiology or get overruled by nonaversive real-life encounters.

Abstract
In the 3 decades since Liebowitz's review of 'a neglected anxiety disorder,' controversy and challenges have remained in the study of social anxiety disorder (SAD). This review examines evidence around the classification and subtyping of SAD, focusing on generalized SAD. Substantial discrepancies and variation in definition, epidemiology, assessment, and treatment of generalized SAD exist as the international literature on it has grown. In East Asian cultures in particular, study of taijin kyofusho has been important to a broadened conceptualization of SAD into generalized SAD. Despite important progress with biological and other studies, many challenges in the understanding of generalized SAD will remain in the years to come.

Abstract
OBJECTIVES Although the short-term outcome of therapist-guided internet-based cognitive-behavioural therapy (ICBT) for treating social anxiety disorder (SAD) has been well studied, little research has been undertaken on the sustainability of treatment gains, especially under clinically representative conditions. Further, there is some debate whether delivering psychological treatment via the internet may be suitable for more severely ill patients. DESIGN Longitudinal multilevel growth-modelling of long-term (1-4 years) follow-up cohort data. SETTING An outpatient psychiatric clinic specialised in internet interventions. PARTICIPANTS 446 adults having been treated for SAD. PRIMARY AND SECONDARY OUTCOME MEASURES Primary outcomes were estimated improvement rate and Cohen's d effect size on the self-rated Liebowitz Social Anxiety Disorder Scale. Secondary outcome measures were change in comorbid depressive symptoms and health-related quality of life. RESULTS A large treatment effect was observed on the primary outcome measure after treatment (d=0.8 (95% CI 0.7 to 0.9)), with continued long-term improvements (d=1.2 (95% CI 1.0 to 1.3)). However, the rate of change varied significantly between individuals over time. A faster rate of improvement was observed among patients with higher illness severity, whereas having a family history of social anxiety was related to worse response. Long-term improvements were also observed in comorbid depressive symptoms (d=0.7 (95% CI 0.5 to 0.8)) and health-related quality of life (d=-0.3 (95% CI -0.4 to -0.1)). CONCLUSIONS These findings provide evidence for the long-term effectiveness of ICBT for SAD in routine clinical practice, even for more severe cases.

Abstract
BACKGROUND We aimed to provide unbiased estimates of familial risk and heritability of social anxiety disorder (SAD) and avoidant personality disorder (AVPD). METHOD We identified 18 399 individuals diagnosed with SAD and 2673 with AVPD in the Swedish National Patient Register between 1997 and 2009. Risks (odds ratios; OR) for SAD in all biological and non-biological relatives of probands, compared to relatives of unaffected individuals were calculated. We also estimated the risks for AVPD in relatives of probands with SAD. RESULTS The risk for SAD among relatives of SAD probands increased proportionally to the degree of genetic relatedness. The risks for first-degree relatives [OR 4.74, 95% confidence interval (CI) 4.28-5.25] were significantly higher than for second-degree and third-degree relatives. Second-degree relatives (OR 2.30, 95% CI 2.01-2.63) had significantly higher risk than third-degree relatives (OR 1.72, 95% CI 1.52-1.94). Relatives at similar genetic distances had similar risks for SAD, despite different degrees of shared environment. Heritability was estimated to be approximately 56%. There were no significant sex differences in the familial patterns. The risk of AVPD in relatives of SAD probands was significantly elevated, even after excluding individuals with both diagnoses (first-degree OR 3.54, second-degree OR 2.20, third-degree OR 1.62). Non-biological relatives (spouses/partners) also had elevated risks for both SAD (OR 4.01) and AVPD (OR 3.85). CONCLUSIONS SAD clusters in families primarily due to genetic factors. SAD and AVPD are aetiologically related and may represent different expressions of the same vulnerability. The strong marital concordance observed in SAD/AVPD may indicate assortative mating but the exact mechanisms and implications require further investigation.

Abstract
Inheritance is typically associated with the Mendelian transmission of information from parents to offspring by alleles (DNA sequence). However, empirical data clearly suggest that traits can be acquired from ancestors by mechanisms that do not involve genetic alleles, referred to as non-genetic inheritance. Information that is non-genetically transmitted across generations includes parental experience and exposure to certain environments, but also parental mutations and polymorphisms, because they can change the parental 'intrinsic' environment. Non-genetic inheritance is not limited to the first generation of the progeny, but can involve the grandchildren and even further generations. Non-genetic inheritance has been observed for multiple traits including overall development, cardiovascular risk and metabolic symptoms, but this review will focus on the inheritance of behavioral abnormalities pertinent to psychiatric disorders. Multigenerational non-genetic inheritance is often interpreted as the transmission of epigenetic marks, such as DNA methylation and chromatin modifications, via the gametes (transgenerational epigenetic inheritance). However, information can be carried across generations by a large number of bioactive substances, including hormones, cytokines, and even microorganisms, without the involvement of the gametes. We reason that this broader definition of non-genetic inheritance is more appropriate, especially in the context of psychiatric disorders, because of the well-recognized role of parental and early life environmental factors in later life psychopathology. Here we discuss the various forms of non-genetic inheritance in humans and animals, as well as rodent models of psychiatric conditions to illustrate possible mechanisms.

Abstract
Gene expression and regulation is an important sculptor of the behavior of organisms. Epigenetic mechanisms regulate gene expression not by altering the genetic alphabet but rather by the addition of chemical modifications to proteins associated with the alphabet or of methyl marks to the alphabet itself. Being dynamic, epigenetic mechanisms of gene regulation serve as an important bridge between environmental stimuli and genotype. In this review, we outline epigenetic mechanisms by which gene expression is regulated in animals and humans. Using fear learning as a framework, we then delineate how such mechanisms underlie learning and stress responsiveness. Finally, we discuss how epigenetic mechanisms might inform us about the transgenerational inheritance of behavioral traits that are being increasingly reported.

Abstract
Although much has been learned about social anxiety disorder (SAD) in recent decades, many questions and controversies surrounding its diagnosis and treatment have remained. Similar to the state of affairs with other psychiatric disorders, no clear pathophysiology has been identified for SAD, and the question of where to draw the line between shyness, SAD and even avoidant personality disorder continues to be debated. Much of the evidence to date suggests that among persons with SAD, it is under-recognized and undertreated; however, other researchers contend that it may be overdiagnosed in some individuals. Questions also remain as to how best treat these individuals, such as with pharmacotherapy, psychotherapy or a combination of the two. The aim of this review is to provide an overview of the controversies related to the diagnosis and treatment of SAD. In addition, suggestions for future research are provided that could perhaps clarify these remaining questions, such as maximizing treatment efficacy by targeting broader outcomes such as quality of life and addressing common comorbidities that occur with SAD.

Abstract
BACKGROUND Research conducted using small samples of persons exposed to extreme stressors has documented an association between parental and offspring posttraumatic stress disorder (PTSD), but it is unknown whether this association exists in the general population and whether trauma exposure mediates this association. We sought to determine whether mothers' posttraumatic stress symptoms were associated with PTSD in their young adult children and whether this association was mediated by higher trauma exposure in children of women with PTSD. METHODS Using data from a cohort of mothers (n = 6924) and a cohort of their children (n = 8453), we calculated risk ratios (RR) for child's PTSD and examined mediation by trauma exposure. RESULTS Mother's lifetime posttraumatic stress symptoms were associated with child's PTSD in dose-response fashion (mother's 1-3 symptoms, child's RR = 1.2; mother's 4-5 symptoms, RR = 1.3; mother's 6-7 symptoms, RR = 1.6, compared with children of mothers with no symptoms, p < .001 for each). Mother's lifetime symptoms were also associated with child's trauma exposure in dose-response fashion. Elevated exposure to trauma substantially mediated elevated risk for PTSD in children of women with symptoms (mediation proportion, 74%, p < .001). CONCLUSIONS Intergenerational association of PTSD is clearly present in a large population-based sample. Children of women who had PTSD were more likely than children of women without PTSD to experience traumatic events; this suggests, in part, why the disorder is associated across generations. Health care providers who treat mothers with PTSD should be aware of the higher risk for trauma exposure and PTSD in their children.

Abstract
INTRODUCTION There is a lack of studies examining the effectiveness of some of the commonly used instruments to elicit the presence of social anxiety disorder (SAD) in Arab-speaking populations, such as those in Oman. The aim of this study was to establish the influence of social anxiety and the role of gender among Omani adolescents. METHODS A two-phase protocol was used, entailing the psychometric properties of the Arabic version of the Liebowitz Social Anxiety Scale (LSAS) against the gold standard, the Diagnostic and Statistical Manual of Mental Disorders (DSM). RESULTS According to DSM and LSAS, the prevalence of social phobia among Omani students was generally higher compared to what has been reported in other parts of the world and the crosstabs analysis showed a significant correlation between gender and SAD. DISCUSSION The Arabic version of LSAS proved to be an effective tool for assessing and quantifying the presence of SAD. This study discusses the sociocultural factors affecting social phobia in Omani society.

Abstract
Social anxiety disorder (SAD) is highly prevalent and impairing. Little is known about rates and predictors of persistence of SAD in the community. The current study derived data from the National Epidemiologic Survey on Alcohol and Related Conditions, Wave 1 (2001-2002, n = 43,093) and Wave 2 (2004-2005, n = 34,653), a large survey of a representative sample of the United States adult population. Individuals with current DSM-IV SAD at Wave 1 were re-interviewed 3 years later at Wave 2 using the Alcohol Use Disorder and Associated Disabilities Interview Schedule-DSM IV Version (AUDADIS-IV). We found that in the community, 22.3% of respondents with SAD at the Wave 1 evaluation met DSM-IV criteria for SAD three years later, and endorsement of social interaction fears and a higher number of avoided social situations, treatment-seeking during past year, and comorbidity with mood disorders independently predicted persistence of SAD. These results suggest that persistence of SAD in the community is common and associated with symptom severity and comorbid mood disorders.

Abstract
We explore paternal social anxiety as a specific risk factor for childhood social anxiety in a rational optimization model. In the course of human evolution, fathers specialized in external protection (e.g., confronting the external world) while mothers specialized in internal protection (e.g., providing comfort and food). Thus, children may instinctively be more influenced by the information signaled by paternal versus maternal behavior with respect to potential external threats. As a result, if fathers exhibit social anxiety, children interpret it as a strong negative signal about the external social world and rationally adjust their beliefs, thus becoming stressed. Under the assumption that paternal signals on social threats are more influential, a rational cognitive inference leads children of socially anxious fathers to develop social anxiety, unlike children of socially anxious mothers. We show in the model that mothers cannot easily compensate for anxious paternal behavior, but choose to increase maternal care to maintain the child's wellbeing. We discuss research directions to test the proposed model as well as implications for the prevention and treatment of child social anxiety.

Abstract
BACKGROUND There has been evidence from Western countries of the familial aggregation of personality disorder (PD) in clinical populations. Nonetheless, it is not clear if the results apply to nonclinical population or non-Western countries. The aim of this study is to provide evidence about the familial aggregation of PD using an epidemiological sample of high school students and their parents in Beijing, China. METHOD A sample of high school students (at least 18 years old) and their parents was drawn by stratified cluster sampling. Personality disorder in students was assessed via a two-stage approach, Personality Diagnostic Questionnaire (PDQ) as a screening tool and International Personality Disorder Examination as the diagnostic tool. Parents completed the PDQ. Univariate and multivariate analyses were used to address the familial aggregation of PD. RESULTS Students' PDQ scores were correlated with parents' PDQ scores. Parents of PD students scored higher in PDQ and were more likely to be PD cases than controls' parents (adjusted odds ratio, 6.4-18.8). LIMITATIONS Student controls and parents are only assessed by PDQ-4. CONCLUSION Obvious familial aggregation of PD was observed in this study. Psychiatrists may consider asking about family history when diagnosing PD.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
BACKGROUND The Social Interaction Anxiety Scale and Social Phobia Scale are companion measures for assessing symptoms of social anxiety and social phobia. The scales have good reliability and validity across several samples, however, exploratory and confirmatory factor analyses have yielded solutions comprising substantially different item content and factor structures. These discrepancies are likely the result of analyzing items from each scale separately or simultaneously. The current investigation sets out to assess items from those scales, both simultaneously and separately, using exploratory and confirmatory factor analyses in an effort to resolve the factor structure. METHODS Participants consisted of a clinical sample (n 5353; 54% women) and an undergraduate sample (n 5317; 75% women) who completed the Social Interaction Anxiety Scale and Social Phobia Scale, along with additional fear-related measures to assess convergent and discriminant validity. RESULTS A three-factor solution with a reduced set of items was found to be most stable, irrespective of whether the items from each scale are assessed together or separately. Items from the Social Interaction Anxiety Scale represented one factor, whereas items from the Social Phobia Scale represented two other factors. CONCLUSION Initial support for scale and factor validity, along with implications and recommendations for future research, is provided.

Abstract
The present study examined the development of elevated startle reactivity in anticipation of mild anxiogenic procedures in school-age children with current anxiety disorders and in those at-risk for their development due to parental anxiety. Startle blink reflexes and skin conductance responses were assessed in 7 to 12 year old anxious children (N=21), non-anxious children at-risk for anxiety by virtue of parental anxiety disorder status (N=16) and non-anxious control children of non-anxious parents (N=13). Responses were elicited by 28 auditory startle stimuli presented prior to undertaking mild anxiogenic laboratory procedures. Results showed that group differences in startle reactivity differed as a function of children's age. Relative to control children for whom age had no effect, startle reflex magnitude in anticipation of anxiogenic procedures increased across the 7 to 12 years age range in children at-risk for anxiety disorders, whereas elevations in startle reactivity were already manifest from a younger age in children with anxiety disorders. These findings may suggest an underlying vulnerability that becomes manifest with development in offspring of anxious parents as the risk for anxiety disorders increases.

Abstract
Die Soziale Phobie (oder Soziale Angststörung) stellt eine häufige psychische Störung dar, die insbesondere aufgrund ihres chronischen Verlaufs mit umfassenden Beeinträchtigungen einhergeht. Voraussetzung für die langfristig wirksame Behandlung oder Prävention der Störung ist ein umfassendes Verständnis bedingender und aufrecht erhaltender Faktoren. Mittlerweile liegen neben einer Reihe deskriptiver Störungsmodelle zur Entstehung und Aufrechterhaltung eine Vielfalt empirischer Ergebnisse zu Risikofaktoren sozialer Ängste vor. Neben einem Überblick über Phänomenologie und Epidemiologie Sozialer Angststörungen liegt der Schwerpunkt der Arbeit auf der Diskussion möglicher Einflussfaktoren in einer Entwicklungspsychopathologie der Sozialen Phobie. Dabei werden internale Faktoren, wie Familiengenetik, Temperament, kognitive Stile und soziale Fertigkeiten, sowie externe Faktoren, wie Erziehungsverhalten der Eltern und Erfahrungen mit der sozialen Umwelt, berücksichtigt. Zur Integration dieser Befunde werden differenzierte Modelle zur Ausbildung und zu differenziellen Entwicklungsverläufen generalisierter und isolierter sozialer Ängste vorgeschlagen.

Abstract
The present study examined threat interpretation biases in children 7-12 years of age with separation, social and generalised anxiety disorders (N=15), non-anxious offspring at risk due to parental anxiety (N=16) and non-anxious controls of non-anxious parents (N=14). Children provided interpretations of ambiguous situations to assess cognitive, emotional and behavioural responses. In comparison with non-anxious control children and at-risk children who did not differ from each other, anxious children reported stronger negative emotion and less ability to influence ambiguous situations. These results suggest that threat interpretation bias may be a cognitive factor associated with ongoing childhood anxiety but not a vulnerability factor associated with parental anxiety.

Abstract
Data from the Children in the Community Study, a prospective longitudinal investigation, were used to investigate the association of personality disorder (PD) traits, evident by early adulthood, with risk for development of anxiety disorders by middle adulthood. Individuals without a history of anxiety disorders who met diagnostic criteria for >or=1 PD by early adulthood were at markedly elevated risk for agoraphobia, generalized anxiety disorder, obsessive-compulsive disorder, and panic disorder by middle adulthood. Antisocial, avoidant, borderline, dependent, depressive, histrionic, obsessive-compulsive, passive-aggressive, and schizotypal PD traits, evident by early adulthood, were associated with elevated risk for >or=1 anxiety disorder during middle adulthood. These associations remained significant after a history of anxiety disorder and co-occurring Axis I psychiatric disorder was controlled statistically. Findings of this study suggest that some types of PD traits that become evident by early adulthood may contribute to increased risk for the development of anxiety disorders by middle adulthood.

Abstract
Personality traits and most anxiety disorders are strongly related. In this article, we review existing evidence for ways in which personality traits may relate to anxiety disorders: 1) as predisposing factors, 2) as consequences, 3) as results of common etiologies, and 4) as pathoplastic factors. Based on current information, we conclude the following: 1) Personality traits such as high neuroticism, low extraversion, and personality disorder traits (particularly those from Cluster C) are at least markers of risk for certain anxiety disorders; 2) Remission from panic disorder is generally associated with partial "normalization" of personality traits; 3) Anxiety disorders in early life may influence personality development; 4) Anxiety disorders and personality traits are usefully thought of as spectra of common genetic etiologies; and 5) Extremes of personality traits indicate greater dysfunction in patients with anxiety disorders.

Abstract
Social phobia (social anxiety disorder) was officially recognized as a distinct clinical entity only with the publication of the DSM-III in 1980. Research on the psychopathology of this disorder has revealed a great degree of heterogeneity in its symptomatology. In order to acknowledge this heterogeneity, later versions of the nosological system introduced the generalized subtype of social phobia to describe individuals who fear most or all social situations. The empirical literature on the differences between the diagnostic subtypes has yielded inconsistent findings. Based on the recent emotion literature and concepts from evolutionary psychology, we discuss fearfulness, anxiousness, shyness, self-consciousness, submissiveness, and anger as dimensions of social phobia. The empirical evidence for this classification system and its relationship to the diagnostic subtypes will be discussed.

Abstract
General population data was used to examine if empirically derived subtypes of social phobia with and without avoidant personality disorder (APD) could be differentiated on self-report measures of anxiety severity, level of global functioning and the number of fulfilled diagnostic criteria for other personality disorders. DSM-IV diagnoses of social phobia, APD and indices of other personality disorders were determined by means of a postal survey. The presence of APD was associated with compromised functional status and a higher frequency of fulfilled diagnostic criteria for additional personality disorders. However, APD did not modify the effect of social phobia subtypes on anxiety severity, level of global functioning or number of personality disorder indices. The presence of comorbid APD in social phobics seems to predict a global functioning decrement independent of anxiety severity. The results imply that social phobia and APD may represent different points on a severity continuum rather than easily defined discreet categories suggesting that social phobia and APD may represent a spectrum of anxiety symptoms related to social anxiety.

Abstract
Social phobia, or social anxiety disorder, is now considered the most common anxiety disorder. Still, the etiology of the disorder is to an essential degree unknown. This paper presents an overview of various pathways to be considered in relation to the development of social phobia. The literature concerning genetics and family aggregation, behavioral inhibition, various forms of the learning account, and neurobiological influences was examined. The reviewed studies suggest that social phobia has a neuroanatomical basis in a highly sensitive fear network centered in the amygdaloid-hippocampal region, i.e. "the alarm system" of the brain, and encompassing the prefrontal cortex. This pattern is congruent with genetic studies proposing that the genetic component comprises a general vulnerability to fearfulness rather than to social phobia itself. Further, both family and twin studies support a hereditary contribution to social phobia resulting from genetic and environmental factors, which most likely operate in an interactive way rather than acting in isolation.

Abstract
In this article, we summarize research on how normal personality and personality disorder traits may relate to anxiety disorders as predisposing factors, complications, and results of common underlying etiologies. We outline important questions and how these may be addressed through future research using genetically informative longitudinal and other designs, including: Are high neuroticism/cluster C personality traits causally related to the development of anxiety disorders? To what extent does the state of having an anxiety disorder influence the assessment of personality traits? Do high neuroticism/personality disorder traits and anxiety disorders co-occur because of shared genetic and environmental determinants? And, do personality disorder traits add to the prediction of anxiety disorders when normal personality traits are taken into account?

Abstract
Negative evaluation fears figure prominently in the cognitive psychology of patients with social phobia. In this study, we examine the heritability of negative evaluation fears by using a twin sample. The authors also examine the relationships between negative evaluation fears and personality dimensions relevant to social phobia. Scores on the brief version of the Fear of Negative Evaluation Scale (BFNE) were examined in a sample of 437 (245 monozygotic and 192 dizygotic) twin pairs. Biometrical model fitting was conducted by using standard statistical methods. Genetic and environmental correlations with personality dimensions (from the Dimensional Assessment of Personality Pathology-Basic Questionnaire) were also calculated. Broad heritability estimate of the BFNE was 48%. Additive genetic effects and unique environmental effects emerged as the primary influences on negative evaluation fears. Genetic correlations between BFNE scores and the submissiveness, anxiousness, and social avoidance facets of the Dimensional Assessment of Personality Pathology-Basic Questionnaire were high (r(g) =.78 to.80). A cognitive dimension central to the phenomenology (and, perhaps, cause) of social phobia, the fear of being negatively evaluated, is moderately heritable. Moreover, the same genes that influence negative evaluation fears appear to influence a cluster of anxiety-related personality characteristics. Implications and limitations of these findings are discussed.

Abstract
The purpose was to assess personality traits in subjects with a DSM-IV diagnosis of social phobia. Thirty-two subjects were administered the Structured Clinical Interview for DSM-IV for Axes I and II disorders (SCID I and II). Personality traits were assessed by means of the Karolinska Scales of Personality (KSP). Current and lifetime axis I co-morbidity was diagnosed in 28% and 53% of the subjects, respectively. In total, 59% had at least one personality disorder and 47% were diagnosed with an avoidant personality disorder. The social phobics scored significantly higher than a Swedish normative sample on the KSP measuring anxiety proneness, irritability, detachment, and indirect aggression but lower on the scales for socialisation and social desirability. The presence as compared to absence of avoidant personality disorder in the social phobics was associated with significantly higher psychic anxiety and inhibition of aggression. In addition, symptom severity was higher in social phobics with an avoidant personality disorder. Generally, the results support the view that social phobia and avoidant personality disorder reflect different aspects of a social anxiety spectrum.
