Estimating the prevalence and characteristics of people in severe social isolation in 29 European countries: A secondary analysis of data from the European Social Survey round 9 (2018-2020).

Abstract
The main aim of the present study was to estimate the prevalence of people in severe social isolation as a proxy for high risk of hikikomori using data from 29 European countries. The relationship between the presence/absence of severe social isolation and demographic and psychosocial variables was also investigated. Publicly available data from the European Social Survey (ESS) round 9 collected between August 2018 and January 2020 were used. Data from the ESS round 1 (September 2002 -December 2003) and round 10 (September 2020 -May 2022) were also examined to investigate changes in the prevalence of severe social isolation over time. Analyses were restricted to the working-age population (15-64 years). A complex sampling design to obtain weighted prevalence and results was used. The study protocol was preregistered online on the Open Science Framework (https://osf.io/6a7br/). The weighted prevalence of severe social isolation was 2.01% for the sample from the ESS 1, 1.77% for the sample from the ESS 9, and 1.71% for the sample from the ESS 10, indicating a decrease over time, mainly in males. Logistic regression models showed that different sociodemographic factors (e.g., being retired, being permanently sick or disabled, doing housework, living in Central and Eastern Europe, living uncomfortably on household income, having no income) were associated with severe social isolation. Further, feeling unsafe when walking alone in the neighbourhood after dark, low social trust, and support, decreased happiness and lack of future planning correlated with severe social isolation after adjustment for the effect of sociodemographic factors was made. In this study, the prevalence of severe social isolation as a proxy for hikikomori in European countries is in line with that found by previous representative studies conducted in Asian countries. The novelty of the findings as well as implications for hikikomori research are discussed according to recent scientific literature.

ATTENTION DEFICIT AND HYPERACTIVITY DISORDERS 2019; 11:271-278.

Abstract
In the present study, our primary aim was to compare the generalized social anxiety (GSAD) patients with and without attention-deficit/hyperactivity disorder (ADHD) in terms of avoidant personality disorder (AVPD), and some clinical variables. We also investigated the relationship of AVPD and depression with ADHD and GSAD. We hypothesized that ADHD may be associated with AVPD in patients with GSAD. Seventy-six patients with GSAD were evaluated for depression, AVPD, and childhood and adulthood diagnoses of ADHD. The GSAD patients with (n = 34) and without adulthood ADHD (n = 30) were compared with respect to some sociodemographic and clinical variables. GSAD patients with adulthood ADHD had significantly higher comorbid diagnosis of AVPD, more avoidant personality and depression symptoms than those without ADHD. Pearson's correlation coefficient in total sample (n = 76) showed that the mean number of AVPD criteria was significantly associated with the severity of Beck Depression Inventory, Wender Utah Rating Scale (WURS), and inattention symptoms of ADHD. There were no correlations between the total and subscale scores of Liebowitz Social Anxiety Scale and the mean number of AVPD criteria. The scores of WURS significantly predicted the mean number of AVPD criteria (β = 0.305, p= 0.007). The severity of current depression (β = 0.143, p = 0.30) and inattention symptoms of adulthood ADHD (β = 0.112, p = 0.46) were not associated with the severity of AVPD symptoms. These results might demonstrate that comorbid AVPD in adult SAD patients was related to a childhood ADHD independent from depression, and inattention symptoms of ADHD in adulthood.

Abstract
Comorbid disorders are highly prevalent in patients with social anxiety disorder, occurring in as many as 90% of patients. The presence of comorbidity may affect the course of the disease in several ways such as comorbidity in patients with social anxiety disorder (SAD) is related to earlier treatment-seeking behavior, increased symptom severity, treatment resistance and decreased functioning. Moreover, comorbidities cause significant difficulties in nosology and diagnosis, and may cause treatment challenges. In this review, major psychiatric comorbidities that can be encountered over the course of SAD as well as comorbidity associated diagnostic and therapeutic challenges will be discussed.

Abstract
Avoidant personality disorder (AVPD) is a relatively common disorder that is associated with significant distress, impairment, and disability. It is a chronic disorder with an early age at onset and a lifelong impact. Yet it is underrecognized and poorly studied. Little is known regarding the most effective treatment. The impetus for research into this condition has waxed and waned, possibly due to concerns regarding its distinctiveness from other disorders, especially social anxiety disorder (SAD), schizoid personality disorder, and dependent personality disorder. The prevailing paradigm subscribes to the "severity continuum hypothesis", in which AVPD is viewed essentially as a severe variant of SAD. However, areas of discontinuity have been described, and there is support for retaining AVPD as a distinct diagnostic category. Recent research has focused on the phenomenology of AVPD, factors of possible etiological significance such as early parenting experiences, attachment style, temperament, and cognitive processing. Self-concept, avoidant behavior, early attachments, and attachment style may represent points of difference from SAD that also have relevance to treatment. Additional areas of research not focused specifically on AVPD, including the literature on social cognition as it relates to attachment and personality style, report findings that are promising for future research aimed at better delineating AVPD and informing treatment.

Abstract
The current study examined whether avoidant personality disorder (AvPD) and social anxiety disorder (SAD) should be considered distinct disorder constructs, which is a persistent and controversial issue in the clinical literature. We examined whether relative scores on SAD and AvPD were associated with the same personality profile and severity of impairment. The current research used a cross-sectional design and self-report inventories, including multiple measures of personality, impairment and psychopathology. Results from a mixed sample of 402 university and community participants found that scores on AvPD and SAD were similarly associated with personality traits and impairment indices. Moreover, a latent construct accounting for the shared variance for AvPD and SAD was associated with personality traits and impairment, whereas the residuals representing the uniquenesses of these disorder constructs were not. These findings support the view that AvPD and SAD are similar disorders from a phenotypic personality trait and impairment perspective. These findings are contrary to a prevalent view in the literature, known as severity continuum hypothesis, because the two disorders could not be meaningfully differentiated based on severity of impairment.

Abstract
This article focuses on the Diagnostic and Statistical Manual of Mental Disorders (DSM) classification of Social Anxiety Disorder (SAD). The article details the diagnostic criteria for SAD that have evolved in the various editions and demonstrates that whilst there have been some positive steps taken to more comprehensively define the disorder, further revision is necessary. It will be argued that the DSM-5 (APA, 2013) has made some changes to the diagnostic criteria of SAD that do not seem to be completely in line with theory and research and do not describe SAD effectively in terms of both diversity and presentation. This article concludes with the presentation of a proposed set of diagnostic criteria that address the concerns raised in the article. The proposed criteria reflect a hybrid categorical-dimensional system of classification.

Abstract
Avoidant personality disorder (AvPD) is regarded as a severe variant of social phobia (SP), consistent with a dimensional model. However, these conclusions are largely drawn from studies based on individuals with SP, with or without comorbid AvPD. The present study hypothesized that there are qualitative differences between AvPD and SP that are undermined by limiting research to participants with SP. The authors sought to test this hypothesis by comparing three groups-SP only, AvPD only, and SP+AvPD-using data extracted from an epidemiological sample of 10,641 adults aged 18 years and over. Screening questions were used in the epidemiological survey to identify ICD-10 personality disorders; from this the author developed a proxy measure for DSM-IV AvPD. Axis I diagnoses, including DSM-IV SP, were identified using the Composite International Diagnostic Interview (CIDI). In this sample, the majority of those with AvPD did not also have SP: The authors found 116 persons with AvPD only, 196 with SP only, and 69 with SP+AvPD. There was little difference between any of the groups on sex, marital status, employment, education, or impairment variables. The SP+AvPD group reported more distress and comorbidity than the SP only and AvPD only groups, which did not differentiate from each other. More feared social situations were endorsed in the SP only group compared to the AvPD only group. Although the finding of few differences between SP only and AvPD only groups among the variables measured in this epidemiological survey fails to provide support for the hypothesis of qualitative differences, the finding that the AvPD only group appears more similar to the SP only group than to the SP+AvPD group also fails to provide support for the alternative continuity hypothesis. The greater distress and additional comorbidity with depression associated with SP+AvPD may be due to the additional symptom load of a second disorder rather than simply representing a more severe variant of social phobia. The use of a proxy for AvPD is a limitation of the study. Future studies should focus on broader clinical variables that have been proposed as qualitatively different between these disorders, and on the possible genetic and environmental factors that might help explain such differences.

Abstract
AIM The aim of the study was to explore the associations between the presence of avoidant personality problems (APPs) and 5 areas of impairment: demography, somatic issues, mental health, lifestyle, and social issues. METHODS Avoidant personality problem was defined by confirmation of the 2 avoidant personality disorder items of the Iowa Personality Disorder Screen and and the Social Phobia Inventory (SPIN) short version (MINI-SPIN) screening assessment for generalized social anxiety disorder sum score of 6 or more. The questionnaires were administered in a Norwegian population survey (the Oslo Health Study-HUBRO). Cases consisted of 280 individuals with APP and 5 randomly selected controls without APP (n = 1400). RESULTS The APP group more frequently reported living alone, lower level of education, and lower income than controls. Poor self-rated health, presence of somatic disease, muscular pain, frequent use of analgesics, and visits at a general practitioner were significantly more common in the APP group than among controls. The APP group had significantly higher proportion of caseness of mental distress, low general self-efficacy, and insomnia, and this result held up in multivariate analyses. The APP group showed statistically significant higher proportions of physical inactivity, obesity, daily smoking, and alcohol problems compared with controls. As for social impairment, a significantly higher proportion of the APP group reported "not having enough good friends," "high powerlessness," and low community activism, and the 2 former variables held up in multivariate analyses. CONCLUSION In this population-based study, we found that high levels of APP, defined closely to avoidant personality disorder, were significantly associated with demographic, somatic, and mental impairment; low general self-efficacy; and insomnia affecting work ability. In addition, APP showed associations with negative lifestyle, alcohol problems, and social impairment reporting lack of good friends and lack of empowerment. Avoidant personality problem is associated with clinically significant impairment in several areas, which underlines the importance of recognizing these problems in primary health care.

Abstract
OBJECTIVE Previous research suggests high levels of comorbidity between social phobia and paranoid symptoms, although the nature of this association remains unclear. METHOD Data were derived from the Early Developmental Stages of Psychopathology study, a 10-year longitudinal study in a representative German community sample of 3021 participants aged 14-24 years at baseline. The Munich-Composite International Diagnostic Interview was used to assess social phobia and paranoid symptoms, along with data on social phobia features. Cross-sectional and longitudinal analyses were conducted. Differential associations with environmental risk factors and temperamental traits were investigated. RESULTS Lifetime social phobia and paranoid symptoms were associated with each other cross-sectionally (OR = 1.80, 95% CI = 1.31-2.47). Lifetime paranoid symptoms were associated specifically with social anxiety cognitions. Lifetime cognitions of negative evaluation predicted later onset of paranoid symptoms, whereas onset of social phobia was predicted by cognitions of loss of control and fear/avoidance of social situations. Lifetime social phobia and paranoid symptoms shared temperamental traits of behavioural inhibition, but differed in environmental risks. CONCLUSIONS The present study showed that paranoid symptoms and social phobia share similarities in cognitive profile and inhibited temperament. Avoidance appears to be important in the development of social phobia, whereas cannabis use and traumatic experiences may drive paranoid thinking in vulnerable individuals.

Abstract
BACKGROUND Behavioral inhibition (BI), a heritable temperament, predisposes one to an increased risk of social phobia. Recent investigations have reported that BI may also be a precursor to anxiety as well as depressive and alcohol-related disorders, which are frequently comorbid with social phobia. In the present study, we explored the relationship between BI and psychiatric disorders in 256 adults with a primary diagnosis of social phobia. METHODS BI severity was retrospectively assessed with the Retrospective Self-Report of Inhibition (RSRI). The severity of social phobia and the presence of comorbid diagnoses were evaluated with the Liebowitz Social Anxiety Scale (LSAS) and the Mini-International Neuropsychiatric Interview, respectively. RESULTS The RSRI score was significantly and positively correlated with both the LSAS score and the occurrence of a major depressive disorder. No significant association was found with other anxiety and substance-related disorders. LIMITATION The assessment of BI was retrospective and self-reported. CONCLUSION A childhood history of BI was associated with an increased risk of depressive comorbidity in social phobia.

Abstract
Within the last decade, social anxiety disorder (SAD) has been identified as a highly prevalent and burdensome disorder. Both the characterization of its symptomatology and effective treatment options are widely documented. Studies particularly indicate that SAD aggregates in families and has its onset in early adolescence. Given the family as an important context for children's cognitive, emotional and behavioural development, familial risk factors could be expected to significantly contribute to the reliable detection of populations at risk for SAD. Reviewing studies on familial risk factors for SAD argues for the importance of parental psychopathology and unfavourable family environment, but also denotes to several shortcomings such as cross-sectional designs, short follow-up periods, diverging methodologies and the focus on isolated factors. Using a prospective longitudinal study that covers the high-risk period for SAD, including a broader spectrum of putative risk factors may help to overcome many of the methodological limitations. This review sets out to develop a more family-oriented approach for predicting the onset and maintenance of SAD that may be fruitful to derive targeted prevention and early intervention in SAD.

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
A developmental-evolutionary perspective is used to synthesize basic research from the neurosciences, ethology, genetics, and developmental psychology into a unified framework for understanding the nature and origins of social anxiety and avoidant personality disorder. Evidence is presented that social anxiety disorder (social phobia) and avoidant personality disorder may be alternate conceptualizations of the same disorder because they have virtually the same symptoms and genetic basis, and respond to the same pharmacologic and psychotherapeutic interventions. A functionalist perspective on social anxiety is formulated to (a) explain the origins of normative states of anxiety, (b) outline developmental pathways in the transition from normative anxiety to social anxiety and avoidant personality disorders, and (c) account for the processes leading to gender-differentiated patterns of anxiety-related disorders after puberty.

Abstract
OBJECTIVE There has been ongoing clinical controversy dating back to the revised third edition of the Diagnostic and Statistical Manual of Mental Disorders concerning the boundaries and extent of overlap between Axis I generalized social phobia (GSP) and Axis II avoidant personality disorder (APD). This study sought to examine the relationship between the fourth edition of Diagnostic and Statistical Manual of Mental Disorders GSP and APD in a large nationally representative sample of the United States population. METHOD We used the National Epidemiologic Survey on Alcohol and Related Conditions (n=43,093; age 18+; response rate=81%) to study fourth edition of Diagnostic and Statistical Manual of Mental Disorders Axes I and II psychiatric disorders, assessed by a reliable semi-structured in-person interview. RESULTS The lifetime prevalence was 2.8% for GSP and 2.4% for APD. The overlap between GSP and APD varied according to the number of GSP social situations feared. Although 36.4% of individuals with GSP were diagnosed with APD, the majority (57.3%) of individuals with GSP who feared all 13 social situations assessed were diagnosed with APD. Nearly 40% of individuals with APD also had GSP. Compared to individuals with GSP alone, individuals with comorbid GSP and APD showed significantly lower mental health-related quality of life on the Medical Outcomes Study Short Form, more interaction and observation fears, and an increased likelihood of having other psychiatric disorders such as major depression. CONCLUSIONS APD and GSP show a high degree of overlap (16-57%), depending on the number of social situations feared. Overall, results suggest that APD and GSP appear to be highly related, but potentially separable constructs. Further research is needed to identify the determinants and consequences of having either or both diagnoses.

Abstract
This review summarizes past and recent findings in the empiric literature and the evolution of the concepts of avoidant personality disorder (APD) and social phobia (SP). APD is an internally consistent dimensional personality pathology that causes dysfunction that appears to be dimensional rather than a sudden jump in impairment after a certain number of criteria have been met. It has state and trait personality components. Evidence indicates that symptoms are at least partially treatable with psychological or pharmacologic interventions. APD and SP have similar symptoms and treatment response and identical genetics. We can conclude from the empiric evidence that no dividing line exists between APD and SP, with APD merely being the more severe form of the disorder. The best conceptualization is that APD is a dimensional personality pathology that in its attenuated form (SP) resembles an anxiety disorder.

Abstract
There has been considerable controversy about whether generalized social phobia (GSP) and avoidant personality disorder (APD) are redundant diagnostic categories. In light of the ongoing controversy, more data are needed to help determine whether GSP and APD are independent constructs. Data were obtained from 335 people seeking treatment for GSP at a two site clinical trial. Indicators of GSP and APD were obtained along with assessments of demographic factors, level of functioning, and indicators of related psychopathology. Confirmatory factor analyses of indicators of GSP and APD suggested a somewhat better fit for a two-factor solution. Comparisons of GSP patients with and without APD suggested that in addition to having more severe social phobia symptoms, patients with APD were more depressed on a self-report measure and had more functional impairment, thereby suggesting potential utility of the diagnostic category of APD. Furthermore, the presence of APD predicted treatment response, in that patients with APD had more change early in treatment than those without APD. APD and GSP remain highly related constructs, and different aspects of these data support and dispute the utility of the diagnosis of APD in GSP. Possible new directions in conceptualizing APD are discussed.

Abstract
The main explanatory hypothesis for the distinction between social phobia (SP) and avoidant personality disorder (APD) has been the severity continuum hypothesis, stating that APD only differs from SP in terms of severity of dysfunction and symptomatic distress, that is, social anxiety and depressive symptoms. This study aimed at a comprehensive evaluation of this hypothesis in a large sample (n = 2192) of thoroughly assessed patients, most of whom had a diagnosis of personality disorder. Social phobia was stronger associated with APD than with other personality disorders, and APD was stronger associated with SP than with other symptom disorders. Social phobia-pure patients had a higher level of global functioning and lower levels of general symptom distress and interpersonal problems than APD-pure patients. The 2 groups were similar on domains that pertain to social anxiety and introversion, but APD was associated with a broader array of symptoms and interpersonal problems and was substantially lower on the personality domain of conscientiousness. Avoidant personality disorder was stronger associated with eating disorders, and SP was stronger associated with panic disorder. The APD diagnosis seems to capture a broader constellation of symptoms and personality features pointing toward more severe personality dysfunction. Our findings suggest that the severity continuum hypothesis lacks specificity and exploratory power to account for both similarities and differences between SP and APD.

Abstract
Zusammenfassung. Ätiologie, Symptomatik und Verlauf von Angststörungen sind multikausal zu erklären. Ein Teilaspekt der psychobiologischen Erklärungsansätze von Angststörungen sind endokrine Auffälligkeiten, anhand derer bestimmte Unterformen pathologischer Angst charakterisiert werden können. Vor allem die Hypothalamus-Hypophysen-Nebennierenrinde-Achse und das sympathiko-adrenomedulläre System werden im Zusammenhang mit Emotionsregulation und pathologischer Angst untersucht. Beide Hormonsysteme spielen bei der Anpassung an individuelle Belastungssituationen eine bedeutende Rolle und beeinflussen die psychobiologische Anpassung an angstauslösende Situationen nachhaltig. In dieser Überblicksarbeit werden endokrine Dysregulationen der o.g. Hormonsysteme für verschiedene Unterformen von Angststörungen aufgezeigt und bzgl. ihrer ätiologischen Bedeutsamkeit, auch unter Berücksichtigung genetischer Befunde, diskutiert. Darüber hinaus werden erste therapeutische Ansätze, bei denen psychoendokrinologische Methoden genutzt werden, aufgezeigt.
