Incidence of social phobia and identification of its risk indicators: a model for prevention

LoST: A Mental Health Dataset of Low Self-esteem in Reddit Posts

Low self-esteem and interpersonal needs (i.e., thwarted belongingness (TB) and perceived burden-someness (PB)) have a major impact on depression and suicide attempts. Individuals seek social connectedness on social media to boost and alleviate their loneliness. Social media platforms allow people to express their thoughts, experiences, beliefs, and emotions. Prior studies on mental health from social media have focused on symptoms, causes, and disorders. Whereas an initial screening of social media content for interpersonal risk factors and low self-esteem may raise early alerts and assign therapists to at-risk users of mental disturbance. Standardized scales measure self-esteem and interpersonal needs from questions created using psychological theories. In the current research, we introduce a psychology-grounded and expertly annotated dataset, LoST: Low Self esTeem, to study and detect low self-esteem on Reddit. Through an annotation approach involving checks on coherence, correctness, consistency, and reliability, we ensure gold standard for supervised learning. We present results from different deep language models tested using two data augmentation techniques. Our findings suggest developing a class of language models that infuses psychological and clinical knowledge.

Self esteem and clinical features in a clinical sample of children with ADHD and social anxiety disorder

OBJECTIVE

In this study, we aimed to investigate self-esteem and clinical features in clinically referred children and adolescents with attention-deficit/hyperactivity disorder (ADHD) and comorbid Social Anxiety Disorder (SAD) and compare these to children and adolescents without SAD.

METHODS

One hundred and twenty child and adolescent drug-naïve outpatients (6-15 years of age) with a primary diagnosis of ADHD were included. Schedule for Affective Disorders and Schizophrenia for School Age Children-Present and Lifetime Version (K-SADS-PL), was used to evaluate ADHD and comorbidities. Parents filled in clinical and sociodemographic data form, Conners Parent Rating Scale (CPRS) and patients filled in Rosenberg Self-esteem Scale (RSES) and Çapa Social Phobia Scale for children and adolescents (ÇESFÖ).

RESULTS

Forty-six of the 120 (38.3%) children had comorbid SAD. Forty-six patients with SAD (ADHD + SAD group) and 74 patients without SAD (ADHD without SAD group) were compared in terms of the sociodemographic and clinical features, rate of psychiatric comorbidities, and rating scale scores. The rate of inattentive subtype of ADHD (p = 0.009), and social anxiety symptom scores (p < 0.001) were higher and self-esteem was lower (p < 0.001) in the ADHD + SAD group. Additionally, there was a statistically significant correlation between ÇESFÖ scores and CPRS anxiety subscale scores (r = 0.300, p = 0.001), and also Rosenberg self-esteem scale scores (r = 0.470, p < 0.001).

CONCLUSION

Children and adolescents with ADHD who had comorbid SAD may differ from ADHD patients without SAD in terms of ADHD subtype, clinical features and self-esteem.

Hidradenitis suppurativa is associated with childhood and lifetime traumatic events: a case-control study

BACKGROUND

Negative life events in childhood can increase the susceptibility to autoimmune and inflammatory diseases. Hidradenitis suppurativa (HS) is a systemic inflammatory disease affecting the apocrine sweat glands, characterized by abscesses, fistulas and inflammatory nodules. It is unknown whether adult HS is associated with traumatic events.

OBJECTIVE

To investigate the association between childhood and total lifetime traumatic events and the presence of HS.

METHODS

We conducted a matched (1 : 3) case-control study with 71 HS patients and 213 controls. Patients were matched on age, gender and level of education. Questionnaires on general and demographic information, as well as the Traumatic Experience Checklist and the Hospital Anxiety and Depression Scale, were completed.

RESULTS

The number of traumatic events (OR: 1.20 per trauma, P value < 0.05), and childhood traumatic events (yes vs. no, OR 3.59, P value < 0.05) and the number of childhood traumatic events (OR 1.35 per trauma, P value < 0.05) were correlated with an increased risk of developing HS. Detailed analysis showed that childhood emotional traumatic events (OR 5.03, P value < 0.05) were significantly associated with the development of HS.

CONCLUSION

Number of lifetime traumatic events and childhood traumatic events are associated with HS. This association is strongest for emotional childhood traumas. The increased prevalence of childhood traumas in HS patients can be one of the underlying mechanisms leading to systemic inflammation in these patients.

The predictive specificity of psychological vulnerability markers for the course of affective disorders

High scores on markers of psychological vulnerability have been associated with a worse course of affective disorders. However, little is known about the specificity of those associations in predicting the course of different depressive and anxiety disorders. We examined the impact of psychological vulnerability on the short- and long-term course of depressive and anxiety disorders. Participants from the Netherlands Study of Depression and Anxiety with a current diagnosis of depression or anxiety (n = 1256) were reassessed after 2 and 6 years. Diagnostic status and chronic duration (>85% of the time) of symptoms were the outcomes. Predictors were neuroticism, extraversion, locus of control, cognitive reactivity (rumination and hopelessness reactivity), worry and anxiety sensitivity. High neuroticism, low extraversion and external locus of control predicted chronicity of various affective disorders. Rumination, however, predicted chronicity of depressive but not anxiety disorders. Worry specifically predicted chronicity of GAD and anxiety sensitivity predicted chronicity of panic disorder and social anxiety disorder. These patterns were present both at short-term and at long-term, without losing predictive accuracy. Psychological vulnerabilities that are theoretically specific to certain disorders indeed selectively predict the course of these disorders. General markers of vulnerability predicted the course of multiple affective disorders. This pattern of results supports the notion of specific as well as transdiagnostic predictors of the course of affective disorders and is consistent with hierarchical models of psychopathology.

Comorbid PTSD and Social Anxiety Disorder: Associations With Quality of Life and Suicide Attempts

Posttraumatic stress disorder (PTSD) and social anxiety disorder (SAD) frequently co-occur. Preliminary data from treatment-seeking and veteran samples suggest that the impact of PTSD-SAD comorbidity may be additive, conferring distress and impairment beyond that of either disorder alone. The current study sought to clarify and extend existent research using wave 2 of the National Epidemiologic Survey of Alcohol and Related Conditions, an epidemiological sample of American adults. Individuals who met criteria for comorbid PTSD-SAD were compared to those with either disorder alone on measures of lifetime suicide attempts or quality of life as measured by the Medical Outcomes Study Questionnaire. Relative to those with either PTSD or SAD, individuals with comorbid PTSD-SAD demonstrated an elevated risk of lifetime suicide attempts and substantially lower levels of physical and mental quality of life. The psychosocial consequences of PTSD-SAD comorbidity are substantial. Patients may benefit from early interventions to remediate social distress and improve support networks before more intensive psychotherapeutic interventions.

PTSD, social anxiety disorder, and trauma: An examination of the influence of trauma type on comorbidity using a nationally representative sample

Posttraumatic stress disorder (PTSD) and social anxiety disorder (SAD) are highly comorbid (Collimore et al., 2010). Trauma may present a shared environmental factor contributing to the development of comorbidity; however, existent research has been hampered by use of restrictive samples and limitations in the range of traumas investigated. The current study examines the relationship between a broad range of potentially traumatic events and the comorbidity between PTSD and SAD using Wave 2 of the National Epidemiological Survey of Alcohol and Related Conditions (n=34,653). Multiple logistic regressions and cross-tabulations were used to evaluate differences in the prevalence of potentially traumatic events among those who met criteria for comorbid PTSD-SAD compared to those with PTSD without SAD and SAD without PTSD. Those in the comorbid PTSD-SAD group were significantly more likely than those in the PTSD without SAD or SAD without PTSD groups to report experiencing specific types of assaultive violence, childhood maltreatment, and other shocking events. Associations between comorbidity and childhood maltreatment were significant for females only. Individuals diagnosed with comorbid PTSD-SAD are more likely than those diagnosed with either disorder alone to report exposure to specific types of traumatic events within their lifetime.

Self-esteem and fear of negative evaluation as mediators between family socioeconomic status and social anxiety in Chinese emerging adults

AIMS

The social causation hypothesis suggests that the stress in connection with a depressing social position results in the development of mental disorders. This study examines the psychological mechanisms underlying the link between family socioeconomic status (SES) and social anxiety in Chinese emerging adults.

METHODS

A self-administered questionnaire was given to a representative sample (N = 717) of undergraduate students (17-23 years old) at three universities in China. Correlational and structural equation modeling analyses were employed to test the hypothesized three-path effect of self-esteem and fear of negative evaluation (FNE) as mediators between family SES and social anxiety.

RESULTS

Findings suggest the following: (1) the emerging adults belonging to families with low SES are at an increased risk of social anxiety, and (2) lower family SES caused lower self-esteem, which, in turn, serves to enhance the levels of FNE, thereby increasing social anxiety.

CONCLUSION

In addressing the prevention and treatment of social anxiety, we conclude that preventive efforts toward improving self-esteem may help reduce social anxiety in individuals with low family SES.

Are there associations between early emotional trauma and anxiety disorders? Evidence from a systematic literature review and meta-analysis

BACKGROUND

Previous studies indicate a possible association between early emotional trauma (EET) and the development of anxiety disorders (ADs) in adult life. However, no previous studies have compiled the findings of such studies and analyzed their statistical significance. Therefore, the objective of this study was to conduct a systematic literature review and meta-analysis to determine possible associations between EET and three ADs (panic, generalized anxiety, and social anxiety disorders).

METHODS

A systematic search was conducted in PubMed, PsycInfo, and Scielo with no publication date limitations. A total of 2127 studies were found, 32 studies of which were selected for the systematic review and 13 studies of which were selected for the meta-analysis.

RESULTS

High prevalence rates of different EETs were observed among the individuals with ADs (median: 18%-45%). The results of the meta-analysis indicated that individuals with EETs were 1.9- to 3.6-fold more likely to develop ADs compared with a control group of healthy individuals. Emotional traumas were the main risk factor for social anxiety disorder. However, no specific associations were found for the other ADs.

CONCLUSIONS

EET is a risk factor for ADs, underscoring the importance of preventive measures to combat the development of these disorders. Moreover, the identification of EETs among patients with ADs is essential for implementing remedial measures to minimize the impact and damage arising from this association by decreasing the risk and severity of symptoms and to improve the response rate to treatment of ADs.

Risk factors for anxiety disorders: common and specific effects in a national sample

BACKGROUND

Anxiety disorders and major depressive disorder (MDD) often co-occur and share a broad range of risk factors. The goal of this study was to examine whether the co-occurrence of anxiety disorders and MDD could be explained by an underlying latent factor and whether the risk factors exert their effect exclusively through this factor, directly on each disorder, or through a combination of effects at both levels.

METHODS

Data were drawn from a large, nationally representative sample. Confirmatory factor analysis was used to identify the latent structure of anxiety disorders. A multiple indicators multiple causes (MIMIC) approach was used to assess the common and specific effects of risk factors for anxiety disorders.

RESULTS

A one-factor model provided a good fit to the co-occurrence of anxiety disorders. Low self-esteem, family history of depression, female sex, childhood sexual abuse, White race, years of education, number of traumatic experiences, and disturbed family environment increased the risk of anxiety disorders and MDD through their effect on the latent factor. There were also several direct effects of the covariates on the disorders, indicating that the effect of the covariates differed across disorders.

CONCLUSIONS

Risk for anxiety disorders and MDD appears to be mediated partially by a latent variable underlying anxiety disorders and MDD, and partially by disorder-specific effects. These findings may contribute to account for the high rates of comorbidity among disorders, identify commonalities in the etiologies of these disorders, and provide clues for the development of unified preventive interventions.

Decrease in self-esteem mediates the association between symptoms of social phobia and depression in middle adolescence in a sex-specific manner: a 2-year follow-up of a prospective population cohort study

BACKGROUND

Social phobia and depression are common, highly comorbid disorders in middle adolescence. The mechanism underlying this comorbidity, however, is unclear. Decrease in self-esteem caused by the initial disorder might play a decisive role in the development of the subsequent disorder. The present study aimed to determine whether the association between symptoms of social phobia and depression is mediated by decrease in self-esteem in mid-adolescent girls and boys.

METHODS

As a part of the prospective Adolescent Mental Health Cohort (AMCH), subjects of this study were 9th grade pupils (mean age, 15.5) responding to a survey conducted in 2002-2003 (T1) and to a 2-year follow-up survey in 2004-2005 (T2) (N = 2070, mean age 17.6 years, 54.5% girls).

RESULTS

Symptoms of social phobia without symptoms of depression at age 15 and symptoms of depression at age 17 were associated only among boys, and this association was mediated by decrease in self-esteem. Symptoms of depression without symptoms of social phobia at age 15 and symptoms of social phobia at age 17 were associated only among girls, and this association was partially mediated by decrease in self-esteem.

CONCLUSIONS

Decrease in self-esteem plays a decisive role in the association between social phobia and depression. Self-esteem should be a key focus in interventions for adolescents suffering from social phobia or depression. Efficient intervention for the first disorder might help to prevent the decline in self-esteem and thus the incidence of the subsequent disorder. These findings are based on a sample of Finnish adolescents and should be confirmed in other jurisdictions or in more ethnically diverse samples.

Implicit and explicit self-esteem and their reciprocal relationship with symptoms of depression and social anxiety: a longitudinal study in adolescents

BACKGROUND AND OBJECTIVES

A negative self-view is a prominent factor in most cognitive vulnerability models of depression and anxiety. Recently, there has been increased attention to differentiate between the implicit (automatic) and the explicit (reflective) processing of self-related evaluations. This longitudinal study aimed to test the association between implicit and explicit self-esteem and symptoms of adolescent depression and social anxiety disorder. Two complementary models were tested: the vulnerability model and the scarring effect model.

METHOD

Participants were 1641 first and second year pupils of secondary schools in the Netherlands. The Rosenberg Self-Esteem Scale, self-esteem Implicit Association Test and Revised Child Anxiety and Depression Scale were completed to measure explicit self-esteem, implicit self-esteem and symptoms of social anxiety disorder (SAD) and major depressive disorder (MDD), respectively, at baseline and two-year follow-up.

RESULTS

Explicit self-esteem at baseline was associated with symptoms of MDD and SAD at follow-up. Symptomatology at baseline was not associated with explicit self-esteem at follow-up. Implicit self-esteem was not associated with symptoms of MDD or SAD in either direction.

LIMITATIONS

We relied on self-report measures of MDD and SAD symptomatology. Also, findings are based on a non-clinical sample.

CONCLUSIONS

Our findings support the vulnerability model, and not the scarring effect model. The implications of these findings suggest support of an explicit self-esteem intervention to prevent increases in MDD and SAD symptomatology in non-clinical adolescents.

Childhood determinants of adult psychiatric disorder

The aim of this project was to assess the current evidence from longitudinal studies for childhood determinants of adult mental illness. Because of the variable and often prolonged period between factors in childhood and the identification of mental illness in adults, prospective studies, particularly birth cohorts, offer the best chance of demonstrating associations in individuals.

A review was undertaken in 2006 of the published literature from longitudinal studies, together with some large-scale retrospective studies and relevant reviews which provided supplementary evidence. The main focus was upon potentially ameliorable characteristics, experiences or situations of childhood; however, other factors, not determinants but pre-cursors, associated with later mental illness could not be left out.

Seven major electronic data-bases of published research were interrogated with a range of key-words and the results supplemented from personal searches, enquiries and reference trails. In excess of 1,500 abstracts were read to select 250 papers for full review. The material was assessed in relation to ten factors:

Psychological disturbance; Genetic Influences; Neurological Deviance; Neuroticism; Behaviour; School Performance; Adversity; Child Abuse or Neglect; Parenting and parent-child relationships; Disrupted and Disfunctional Families.

In 2011 the search was repeated for the period 2006 to mid-2011, using the same search terms and supplemented in the same manner. Over 1,800 abstracts emerged and almost 200 papers selected for more detailed review. These were then integrated into the original text with modifications where necessary. The whole text was then revised and edited in January / February 2012.

There is continuing evidence for the association with later mental ill-health for each of these ten factors, but with different degrees of conviction. The evidence for each is discussed in detail and weighed both separately and in relation to others. These are then summarised, and the research implications are considered. Finally, the implications for prevention are discussed together with the practical potential for preventive and health-promoting programmes.

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.

Effects of resocialization on post-weaning social isolation-induced abnormal aggression and social deficits in rats

As previously shown, rats isolated from weaning develop abnormal social and aggressive behavior characterized by biting attacks targeting vulnerable body parts of opponents, reduced attack signaling, and increased defensive behavior despite increased attack counts. Here we studied whether this form of violent aggression could be reversed by resocialization in adulthood. During the first weak of resocialization, isolation-reared rats showed multiple social deficits including increased defensiveness and decreased huddling during sleep. Deficits were markedly attenuated in the second and third weeks. Despite improved social functioning in groups, isolated rats readily showed abnormal features of aggression in a resident-intruder test performed after the 3-week-long resocialization. Thus, post-weaning social isolation-induced deficits in prosocial behavior were eliminated by resocialization during adulthood, but abnormal aggression was resilient to this treatment. Findings are compared to those obtained in humans who suffered early social maltreatment, and who also show social deficits and dysfunctional aggression in adulthood.

Mindfulness-based stress reduction, mindfulness-based cognitive therapy, and Zen meditation for depression, anxiety, pain, and psychological distress

Mindfulness has been described as a practice of learning to focus attention on moment-bymoment experience with an attitude of curiosity, openness, and acceptance. Mindfulness practices have become increasingly popular as complementary therapeutic strategies for a variety of medical and psychiatric conditions. This paper provides an overview of three mindfulness interventions that have demonstrated effectiveness for psychiatric symptoms and/or pain. The goal of this review is to provide a synopsis that practicing clinicians can use as a clinical reference concerning Zen meditation, mindfulness-based stress reduction (MBSR), and mindfulness-based cognitive therapy (MBCT). All three approaches originated from Buddhist spiritual practices, but only Zen is an actual Buddhist tradition. MBSR and MBCT are secular, clinically based methods that employ manuals and standardized techniques. Studies indicate that MBSR and MBCT have broad-spectrum antidepressant and antianxiety effects and decrease general psychological distress. MBCT is strongly recommended as an adjunctive treatment for unipolar depression. The evidence suggests that both MBSR and MBCT have efficacy as adjunctive interventions for anxiety symptoms. MBSR is beneficial for general psychological health and stress management in those with medical and psychiatric illness as well as in healthy individuals. Finally, MBSR and Zen meditation have a role in pain management.

Prognostic value of implicit and explicit self-associations for the course of depressive and anxiety disorders

Dysfunctional self-beliefs are assumed to play an important role in maintaining depression and anxiety. Current dual-process models emphasize the relevance of differentiating between implicit and explicit self-beliefs. Therefore, this study tested the prognostic value of automatic and explicit self-associations for the naturalistic course of depressive and anxiety disorders over two years follow-up. Both self-depressed and self-anxious associations were measured in unipolar depressed patients (n = 313), anxious patients (n = 566), and patients with comorbid depressive and anxiety disorders (n = 577) as part of the Netherlands Study of Depression and Anxiety. Outcomes showed that in single predictor models specifically automatic self-anxious associations were related to a reduced chance of remission from anxiety, whereas automatic self-depressed associations were related to a reduced chance of remission from depression. Explicit self-anxious associations and fearful avoidance behaviour showed independent predictive validity for remission from anxiety, whereas explicit self-depressed associations and having both major depressive disorder and dysthymia showed independent predictive validity for remission from depression. These findings are not only consistent with the view that both implicit and explicit dysfunctional self-associations are related to the course of anxiety and unipolar depressive disorders, but also suggest that both types of self-beliefs are proper targets for therapeutic interventions.

Identifying target groups for the prevention of depression in early adolescence: the TRAILS study

BACKGROUND

Depression in adolescence is associated with long-term adverse consequences. The aim of the present study is to identify target groups at increased risk of developing depression in early adolescence, such that prevention is associated with the largest health benefit at population-level for the least effort.

METHODS

The analyses were conducted on data of the first (age range 10-12) and fourth (age range 17-20) wave of a population-based cohort study (N=1538). The Composite International Diagnostic Interview (CIDI) was used to assess onset of major depression in early adolescence. High-risk groups were identified using exposure rate, incidence rate and population attributable fraction.

RESULTS

Prevention of depression onset in early adolescence is best targeted at children with one of the following risk profiles: a high body mass index in combination with (1) maternal depression (2) female gender, and (3) parental emotional rejection.

LIMITATIONS

Age of onset of depression was assessed retrospectively.

CONCLUSIONS

Only a few risk indicators are needed to identify a relatively small group which accounts for a substantial percentage of the new cases of depression in early adolescence.

Co-occurrence of social anxiety and depression symptoms in adolescence: differential links with implicit and explicit self-esteem?

BACKGROUND

Social anxiety and depression often co-occur. As low self-esteem has been identified as a risk factor for both types of symptoms, it may help to explain their co-morbidity. Current dual process models of psychopathology differentiate between explicit and implicit self-esteem. Explicit self-esteem would reflect deliberate self-evaluative processes whereas implicit self-esteem would reflect simple associations in memory. Previous research suggests that low explicit self-esteem is involved in both social anxiety and depression whereas low implicit self-esteem is only involved in social anxiety. We tested whether the association between symptoms of social phobia and depression can indeed be explained by low explicit self-esteem, whereas low implicit self-esteem is only involved in social anxiety.

METHOD

Adolescents during the first stage of secondary education (n=1806) completed the Revised Child Anxiety and Depression Scale (RCADS) to measure symptoms of social anxiety and depression, the Rosenberg Self-Esteem Scale (RSES) to index explicit self-esteem and the Implicit Association Test (IAT) to measure implicit self-esteem.

RESULTS

There was a strong association between symptoms of depression and social anxiety that could be largely explained by participants' explicit self-esteem. Only for girls did implicit self-esteem and the interaction between implicit and explicit self-esteem show small cumulative predictive validity for social anxiety, indicating that the association between low implicit self-esteem and social anxiety was most evident for girls with relatively low explicit self-esteem. Implicit self-esteem showed no significant predictive validity for depressive symptoms.

CONCLUSIONS

The findings support the view that both shared and differential self-evaluative processes are involved in depression and social anxiety.

Self-referential thinking, suicide, and function of the cortical midline structures and striatum in mood disorders: possible implications for treatment studies of mindfulness-based interventions for bipolar depression

Bipolar depression is often refractory to treatment and is frequently associated with anxiety symptoms and elevated suicide risk. There is a great need for adjunctive psychotherapeutic interventions. Treatments with effectiveness for depressive and anxiety symptoms as well as suicide-related thoughts and behaviors would be particularly beneficial. Mindfulness-based interventions hold promise, and studies of these approaches for bipolar disorder are warranted. The aim of this paper is to provide a conceptual background for such studies by reviewing key findings from diverse lines of investigation. Results of that review indicate that cortical midline structures (CMS) appear to link abnormal self-referential thinking to emotional dysregulation in mood disorders. Furthermore, CMS and striatal dysfunction may play a role in the neuropathology underlying suicide-related thoughts and behaviors. Thus, combining studies of mindfulness interventions targeting abnormal self-referential thinking with functional imaging of CMS and striatal function may help delineate the neurobiological mechanisms of action of these treatments.

Evaluation of a DVD-based self-help program in highly socially anxious individuals--pilot study

High social anxiety is a risk factor for the incidence of social anxiety disorder (SAD). Early diagnosis and intervention may prevent more severe psychiatric courses. Self-help programs may be a convenient, accessible, and effective intervention. This study examined the efficacy of a newly developed self-help program for SAD in individuals with subthreshold social anxiety. A total of 24 highly socially anxious individuals were randomly assigned to a DVD-based self-help program or to a wait-list control group. The self-help program is based on the cognitive model according to Clark and Wells (1995; adapted to German by Stangier, Clark, & Ehlers, 2006) and comprises eight sessions. ANOVAs based on an intention-to-treat model were used for data analyses. The self-help program was well accepted; just one person withdrew during the intervention. There were significant Time× Group interactions on all primary outcome measures. For the intervention group moderate to high within-groups effect sizes up to Cohen's d = 1.05 were obtained. Between-groups effect sizes ranged from 0.24 to 0.65 in favor of the active intervention. The newly developed DVD-based self-help program seems to be a promising intervention for highly socially anxious individuals as it reduces social anxiety symptoms.

Relationship between social phobia and depression differs between boys and girls in mid-adolescence

BACKGROUND

Earlier studies suggest that social phobia (SP) and depression (DEP) often have their onset in adolescence, and are highly comorbid, with SP mainly preceding depression. There is a lack of population-based prospective studies among adolescents vulnerable to both disorders, taking into account possible gender differences in the relationship between the two.

METHODS

This study is part of a prospective Adolescent Mental Health Cohort (AMHC) study. Subjects are 9th grade pupils (mean age 15.5 years (sd 0.39)) responding to a survey conducted 2002-2003 (T1) and a 2-year follow-up 2004-2005 (T2) (N=2038). Social phobia was measured by the Social Phobia Inventory (SPIN) and depression by the 13-item Beck Depression Inventory (BDI-13).

RESULTS

Risk for depression at T2 by SP at T1 was elevated only among boys (OR 3.6, 95% C.I. 1.507-8.579, p=0.004), whereas among girls, risk for SP at T2 by DEP at T1 was elevated (OR 7.8, 95% CI 4.529-13.391, p<0.001). The course of both disorders was unstable and recovery was common.

LIMITATIONS

Lack of diagnostic interviews and fairly high drop-out rate (36.9%) in follow-up.

CONCLUSIONS

The relationship between SP and depression in adolescence seems different for boys and girls. Further studies are needed to explore factors explaining the different course of these disorders among boys and girls. Clinicians need to be alert to comorbidity when examining an adolescent with SP or depression.

Psychiatric history and subthreshold symptoms as predictors of the occurrence of depressive or anxiety disorder within 2 years

BACKGROUND

Past episodes of depressive or anxiety disorders and subthreshold symptoms have both been reported to predict the occurrence of depressive or anxiety disorders. It is unclear to what extent the two factors interact or predict these disorders independently.

AIMS

To examine the extent to which history, subthreshold symptoms and their combination predict the occurrence of depressive (major depressive disorder, dysthymia) or anxiety disorders (social phobia, panic disorder, agoraphobia, generalised anxiety disorder) over a 2-year period.

METHOD

This was a prospective cohort study with 1167 participants: the Netherlands Study of Depression and Anxiety. Anxiety and depressive disorders were determined with the Composite International Diagnostic Interview, subthreshold symptoms were determined with the Inventory of Depressive Symptomatology-Self Report and the Beck Anxiety Inventory.

RESULTS

Occurrence of depressive disorder was best predicted by a combination of a history of depression and subthreshold symptoms, followed by either one alone. Occurrence of anxiety disorder was best predicted by both a combination of a history of anxiety disorder and subthreshold symptoms and a combination of a history of depression and subthreshold symptoms, followed by any subthreshold symptoms or a history of any disorder alone.

CONCLUSIONS

A history and subthreshold symptoms independently predicted the subsequent occurrence of depressive or anxiety disorder. Together these two characteristics provide reasonable discriminative value. Whereas anxiety predicted the occurrence of an anxiety disorder only, depression predicted the occurrence of both depressive and anxiety disorders.

The prognosis and incidence of social phobia in an elderly population. A 5-year follow-up

OBJECTIVE

To examine the prognosis and incidence of social fears and phobia in an elderly population sample followed for 5 years.

METHOD

A general population sample (N = 612) of non-demented men (baseline age 70) and women (baseline age 70 and 78-86) was investigated in 2000-2001 and in 2005-2006 with semi-structured psychiatric examinations including the Comprehensive Psychopathological Rating Scale, and the Mini International Neuropsychiatric Interview. Social phobia was diagnosed according to the DSM-IV criteria.

RESULTS

Among nine individuals with DSM-IV social phobia in 2000, 5 (55.6%) had no social fears in 2005, and 1 (11.1%) still met the criteria for DSM-IV social phobia. Among individuals without DSM-IV social phobia in 2000 (N = 603), 12 (2.0%) had DSM-IV social phobia in 2005.

CONCLUSION

These findings challenge the notion that social phobia is a chronic disorder with rare occurrence in old age.

Identifying target groups for the prevention of anxiety disorders in the general population

OBJECTIVE

To avert the public health consequences of anxiety disorders, prevention of their onset and recurrence is necessary. Recent studies have shown that prevention is effective. To maximize the health gain and minimize the effort, preventive strategies should focus on high-risk groups.

METHOD

Using data from a large prospective national survey, high-risk groups were selected for i) the prevention of first ever (n = 4437) and ii) either first-ever or recurrent incident anxiety disorders (n = 4886). Indices used were: exposure rate, odds ratio, population attributable fraction and number needed to be treated. Risk indicators included sociodemographic, psychological and illness-related factors.

RESULTS

Recognition of a few patient characteristics enables efficient identification of high-risk groups: (subthreshold) panic attacks; an affective disorder; a history of depressed mood; a prior anxiety disorder; chronic somatic illnesses and low mastery.

CONCLUSION

Preventive efforts should be undertaken in the selected high-risk groups.

Childhood life events and childhood trauma in adult patients with depressive, anxiety and comorbid disorders vs. controls

OBJECTIVE

To investigate the association between childhood life events, childhood trauma and the presence of anxiety, depressive or comorbid anxiety and depressive disorders in adulthood.

METHOD

Data are from 1931 adult participants in the Netherlands Study of Depression and Anxiety (NESDA). Childhood life events included divorce of parents, early parental loss and 'placed in care', whereas childhood trauma was assessed as experienced emotional neglect, psychological, physical and sexual abuse prior to age 16.

RESULTS

Childhood life events were not associated with psychopathology, except for 'placed in care' in the comorbid group. All types of childhood trauma were increasingly prevalent in the following order: controls, anxiety, depression, and comorbid group (P < 0.001). The higher the score was on the childhood trauma index, the stronger the association with psychopathology (P < 0.001).

CONCLUSION

Childhood trauma rather than childhood life events are related to anxiety and depressive disorders. The strong associations with the comorbid group suggest that childhood trauma contributes to the severity of psychopathology. Our study underscores the importance of heightened awareness of the possible presence of childhood trauma, especially in adult patients with comorbid anxiety and depressive disorders.

Social anxiety disorder: what are we losing with the current diagnostic criteria?

OBJECTIVE

To assess the rate of comorbidities and the functional impairment associated with the social anxiety disorder (SAD), with an emphasis on the so-called subthreshold clinical signs and symptoms.

METHOD

Psychiatric comorbidities and psychosocial functioning were evaluated in 355 volunteers (college students) who had been diagnosed as SAD (n = 141), Subthreshold SAD (n = 92) or Controls (n = 122).

RESULTS

The rate of comorbidities was 71.6% in the SAD group and 50% in subjects with Subthreshold SAD, both significantly greater than Controls (28.7%). Concerning psychosocial functioning, the SAD group had higher impairment than the other two groups in all domains evaluated, and subjects with Subthreshold SAD presented intermediate values.

CONCLUSION

The rates of psychiatric comorbidities and the impairment of psychosocial functioning increase progressively along the spectrum of social anxiety. The fact that Subthreshold SAD causes considerable disability and suffering in comparison with control subjects justifies a review of the validity of the diagnostic criteria.

Childhood maltreatment linked to greater symptom severity and poorer quality of life and function in social anxiety disorder

BACKGROUND

There is a paucity of data examining the prevalence and impact of childhood maltreatment in patients presenting with a primary diagnosis of social anxiety disorder (SAD). We thus examined the presence of a broad spectrum of childhood maltreatment, including physical, sexual, and emotional abuse and neglect, in treatment-seeking individuals with the generalized subtype of SAD (GSAD). We hypothesized that a history of childhood maltreatment would be associated with greater SAD symptom severity and poorer associated function.

METHODS

One hundred and three participants with a primary diagnosis of GSAD (mean age 37+/-14; 70% male) completed the well-validated, self-rated Childhood Trauma Questionnaire (CTQ), as well as measures of SAD symptom severity and quality of life.

RESULTS

Fully 70% (n=72) of the GSAD sample met severity criteria for at least one type of childhood abuse or neglect as measured by the CTQ subscales using previously established thresholds. CTQ total score adjusted for age and gender was associated with greater SAD severity, and poorer quality of life, function, and resilience. Further, the number of types of maltreatment present had an additive effect, with specific associations for emotional abuse and neglect with SAD severity.

CONCLUSIONS

Despite the use of validated assessments, our findings are limited by the retrospective and subjective nature of self-report measures used to assess childhood maltreatment. Nonetheless, these data suggest a high rate of childhood maltreatment in individuals seeking treatment for GSAD, and the association of maltreatment with greater disorder severity suggests that screening is clinically prudent.
