Abstract

Individuals with social anxiety disorder (SAD) typically have elevated depressive symptoms and approximately 50% also meet criteria for major depressive disorder (MDD; Beesdo et al., 2007). In the present study, we examined the relationship between social anxiety and depressive symptoms during cognitive-behavior group treatment (CBGT) for SAD. Specifically, we compared individuals with SAD and comorbid MDD and individuals with SAD without MDD to examine the role of MDD as a moderator of social anxiety-depression relationship. Participants were 90 individuals seeking treatment for SAD (36% were diagnosed with MDD), who completed self-report measures of social anxiety and depression every 2 weeks during CBGT. Lower level mediational modeling indicated that for individuals without MDD, a reciprocal relationship was observed in which changes in both social anxiety and depressive symptoms mediated changes in each other. However, changes in social anxiety explained all subsequent changes in depression, whereas changes in depression explained 11.26% of subsequent changes in social anxiety. For individuals with both SAD and MDD, neither social anxiety nor depression significantly mediated changes in each other. Our findings suggest that different processes of change occur for individuals with and without MDD and clinical implications of these findings are discussed.

Individuals with social anxiety disorder (SAD) typically have elevated depressive symptoms and approxi-
mately 50% also meet criteria for major depressive disorder (MDD; Beesdo et al., 2007). In the present
study, we examined the relationship between social anxiety and depressive symptoms during cognitive-
behavior group treatment (CBGT) for SAD. Specically, we compared individuals with SAD and comorbid
MDD and individuals with SAD without MDD to examine the role of MDD as a moderator of social
anxietydepression relationship. Participants were 90 individuals seeking treatment for SAD (36% were
diagnosed with MDD), who completed self-report measures of social anxiety and depression every 2 weeks
during CBGT. Lower level mediational modeling indicated that for individuals without MDD, a reciprocal
relationship was observed in which changes in both social anxiety and depressive symptoms mediated
changes in each other. However, changes in social anxiety explained all subsequent changes in depression,
whereas changes in depression explained 11.26% of subsequent changes in social anxiety. For individuals
with both SAD and MDD, neither social anxiety nor depression signicantly mediated changes in each
other. Our ndings suggest that different processes of change occur for individuals with and without MDD
and clinical implications of these ndings are discussed.
Clinical Impact Statement
Question: The present study examined the effect of comorbid MDD on processes of change in
cognitive-behavior group treatment for SAD. Findings: For individuals without MDD, changes in
social anxiety predicted changes in depression, whereas for individuals with MDD, social anxiety and
depression changed independently. Meaning: Individuals with SAD that do not meet criteria for MDD
can be treated using treatments that primarily target social anxiety, and this can lead to reductions in both
social anxiety and depressive symptoms. Individuals with a dual SAD/MDD diagnosis may require
interventions that target shared factors to reduce both social anxiety and depressive symptoms. Next
Steps: Future studies can examine treatments that are tailored to address comorbid MDD in SAD, and
this can lead to enhanced efcacy.

Social anxiety disorder (SAD) is a common, distressing, and
persistent disorder which is associated with signicant impairment
in almost all facets of daily life (Aderka et al., 2012). SAD is
frequently comorbid with major depressive disorder (MDD), with
approximately 50% of individuals with SAD meeting criteria for
MDD over a 10-year period (Beesdo et al., 2007). Comorbid
depressive symptoms among individuals with SAD have been found
to predict SAD persistence (Alpert et al., 1997;Stein et al., 2001),
recurrence (Bruce et al., 2005;Scholten et al., 2013), and treatment
outcome (e.g., Wersebe et al., 2018). In addition, depressive symp-
toms have been found to be associated with severity and generali-
zation of social fears among individuals with SAD (Perugi et al.,

... The severity of symptoms, social disability, and suicide rates indicate that the comorbidity is significantly more serious than "pure" SAD [20]. These studies revealed that SAD comorbidity was associated with early-onset MDD, more frequent depressive episodes, an increased risk of suicide, and higher alcohol consumption [21]. There are limited studies examining the effects of comorbidity on treatment success in SAD [22]. ...
... Additionally, a higher prevalence of the female gender was observed in the MDD-SAD group (59.5% vs 29.2%; P = 0.001). This interesting finding lends support to previous studies indicating a varying gender distribution in SAD and MDD, as well as their comorbidity [20][21][22][23]. Notably, we discovered that depressive complaints in this group were not only more severe but also displayed an atypical pattern (75.7% vs 58.5%; P = 0.010), aligning with the complex presentations often seen in patients with SAD. ...

The comorbidity between the major depressive disorder (MDD) and the social anxiety disorder (SAD) is significantly prevalent, necessitating a nuanced understanding of their overlapping clinical characteristics and shared etiological factors, including inflammatory biomarkers. To address this, we conducted a cross-sectional study from December 2021 to June 2022, encompassing 204 outpatients diagnosed with MDD-SAD comorbidity. We employed various psychometric assessments, such as the Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Childhood Trauma Questionnaire (CTQ-28), Toronto Alexithymia Scale (TAS-20) and the Liebowitz Social Anxiety Scale (LSAS). Additionally, we analyzed inflammatory biomarkers including the neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), neutrophil-to-lymphocyte platelet ratio (NLPR), systemic inflammation index (SII), and the systemic inflammation response index (SIRI). Our findings accentuated that patients primarily diagnosed with MDD exhibited elevated levels of certain inflammatory biomarkers. They reported more severe and atypical depressive symptoms (75.7% vs 58.5%; P = 0.010) and had significantly higher CTQ-28 subscale scores (P < 0.05). Our study unveils a complex relationship between MDD and SAD, with significant disparities in the symptom severity and inflammatory biomarker levels, thereby establishing a compelling case for dual-diagnosis treatment approaches. It elucidates the critical role of inflammation in the comorbidity of MDD and SAD, marking a pioneering step towards more comprehensive and holistic patient care strategies. These insights could potentially revolutionize therapeutic approaches in psychiatric care, promising significantly improved outcomes through early detection and integrated intervention strategies.
... Si consideramos algunas investigaciones por separado (que no forman parte del metaanálisis y la revisión anteriores), encontramos pruebas de una reducción significativa de los síntomas depresivos (d= 0,79) en un grupo de Terapia para la eficacia social (Social Effectiveness Therapy, SET) (Beidel et al., 2014). Rozen et al. (2022) también encontraron que un grupo de terapia cognitivo conductual (GTCC) era eficaz para reducir los síntomas depresivos en sujetos con TAS. Mörtberg et al. (2007) hallaron igualmente una reducción significativa de los síntomas depresivos, siendo mayor la mejoría en la terapia cognitiva individual que en grupo, mientras que Stangier et al. (2003) no encontraron diferencias entre la terapia individual y la grupal en su eficacia para reducir los síntomas depresivos. ...
... Específicamente, comparando los tamaños del efecto del programa IMAS con los informados por otros estudios que evalúan la eficacia de alguna forma de TCC sobre los síntomas depresivos en sujetos con TAS (p. ej., Beidel et al., 2014;Rozen et al., 2022;Stangier et al., 2003), vemos que el programa IMAS muestra un rendimiento superior. Sin embargo, es difícil discutir sobre la preocupación patológica, ya que no conocemos el efecto de las intervenciones psicológicas a este respecto en pacientes con TAS. ...

En un trabajo anterior (Caballo et al., 2021) comprobamos la eficacia del programa de Intervención multidimensional para la ansiedad social (IMAS) en la reducción de los síntomas de ansiedad social. En este estudio cuasiexperimental, con medidas pre/postratamiento y seguimiento, hallamos el impacto del programa IMAS en otros problemas relacionados con la ansiedad social. 57 personas diagnosticadas con un trastorno de ansiedad social (TAS), según el DSM-5, contestaron a cuestionarios que medían habilidades sociales, depresión, síntomas del trastorno de la personalidad por evitación, alcoholismo, autoestima, sensibilidad personal, preocupaciones y calidad de vida. Diferentes terapeutas llevaron a cabo el tratamiento en Ecuador, España y Paraguay. Los resultados mostraron importantes mejoras en el postratamiento en prácticamente todos los aspectos evaluados, mejoras que se mantenían a los seis meses. Los tamaños del efecto sobre la eficacia del tratamiento iban de medianos a grandes. Se comparó también el programa IMAS con terapia cognitivo conductual individual y tratamiento farmacológico, con resultados favorables para el programa IMAS. Este nuevo programa para el tratamiento de la ansiedad social tiene un impacto importante en otros problemas relacionados habitualmente con el TAS.
... If we consider some research separately (not part of the above meta-analysis and review), we find evidence for significant reduction of depressive symptoms (d= 0.79) in a Social Effectiveness Therapy (SET) group (Beidel et al., 2014). Rozen et al. (2022) also found that a cognitive behavioral therapy group (CBGT) was effective in reducing depressive symptoms in subjects with SAD. Mörtberg et al. (2007) similarly found a significant reduction in depressive symptoms, with greater improvement in individual cognitive therapy than in group, while Stangier et al. (2003) found no difference between individual and group therapy in their effectiveness in reducing depressive symptoms. ...
... Thus, it can be expected that as positive reinforcement from exposure increases (and negative reinforcement from avoidance is reduced) they improve their exaggerated worries and depressive symptoms, as shown by the post-treatment results. Specifically, comparing the effect sizes of the MISA program with those reported in other studies evaluating the effectiveness of some form of CBT on depressive symptoms in subjects with SAD (e.g., Beidel et al., 2014;Rozen et al., 2022;Stangier et al., 2003), we see that the MISA program shows superior performance. However, it is difficult to discuss about pathological worry, as we do not know about the effect of psychological interventions in this regard in patients with SAD. ...

In a previous work (Caballo et al., 2021) we tested the effectiveness of the Multidimensional Intervention for Social Anxiety (MISA) program in reducing social anxiety symptoms. In this quasi-experimental study, with pre/post-treatment and follow-up measures, we examined the impact of the MISA program on other problems related to social anxiety. 57 people diagnosed with social anxiety disorder (SAD), according to DSM-5, were assessed with a diagnostic interview and questionnaires measuring social skills, depression, avoidant personality disorder symptoms, alcoholism, self-esteem, personal sensitivity, worries, and quality of life. Different therapists carried out the treatment in Ecuador, Spain, and Paraguay. The results showed significant improvements at post-treatment in virtually all measures assessing the above variables, improvements that were maintained at six months. Effect sizes on treatment effectiveness ranged from medium to large. The MISA program was also compared with individual cognitive behavioral therapy and pharmacological treatment, with favorable results for the MISA program. In conclusion, this new program for the treatment of social anxiety has a significant impact on other problems usually related to SAD.
... It can be assumed that, during necessary hospital treatment, which objectively involves increased health risks, individuals who are removed from their usual way of life and separated from their loved ones perceive the stress of the illness with a significant presence of anxiety and depressive symptoms. However, whether we can attribute this to the social conditioning of anxiety and the relationship between anxiety and depressive symptoms would require separate studies [27]. ...

Introduction. Many studies have shown a correlation between the patient’s engagement in treatment and their perception of the illness. Aim: The aim of this study has been to explore the link between the patient’s perception of their illness with anxiety and depression, and to leverage this link to promote health education. Materials and methods: The study was carried out using the following tools: the Hospital Anxiety and Depression Scale and the Illness Perception Questionnaire–Revised. The study participants included N = 143 patients. Results: The participants’ age was statistically significantly associated with the expected duration of the illness (p < 0.01), the conviction that the treatment was effective (p < 0.01), and the perception of the severity of the disease symptoms (p < 0.05). The employment status was statistically significantly associated with the illness perception (p < 0.01). Anxiety and depression levels were statistically significantly associated with the perceived impact of the illness on life (p < 0.001) and emotional status (p < 0.001), the perceived control over the illness (p < 0.01), the potential for recovery (p < 0.001), the concern about the illness (p < 0.001), and the impact of the illness on emotional well-being (p < 0.001). Conclusions: Individuals who perceived a high severity of illness symptoms also assessed that the illness significantly impacted their life and emotional state. The authors demonstrate a strong link of a “negative” perception of the illness with depression and anxiety. A better understanding of the illness predicted a less severe depression and lower anxiety. Implications for practice: The results suggest that the study of illness perception holds significant potential to contribute effectively to educational and psychotherapeutic practices.

Many individuals with social anxiety disorder (SAD) have depressive symptoms that meet criteria for major depressive disorder (MDD). In our study, we examined the temporal relationship between symptoms of social anxiety and symptoms of depression during the course of an 11-week internet-delivered cognitive behavioral treatment (ICBT) for SAD (n = 170). Specifically, we investigated whether weekly changes in social anxiety mediated changes in depression, changes in depression mediated changes in anxiety, both or neither. In addition, we compared individuals with SAD and MDD (n = 50) and individuals with SAD and no MDD (n = 120) to examine the role of MDD as a moderator of the social anxiety-depression relationship. Lower-level mediational modeling revealed that changes in social anxiety symptoms mediated changes in depression symptoms to a greater extent than vice versa. In addition, mediation among individuals with SAD and MDD was significantly greater compared to individuals with SAD and no MDD. Our findings suggest that ICBT is effective in treating individuals with SAD regardless of comorbid depression, and that focusing ICBT interventions on social anxiety can lead to significant reductions in depression among individuals with SAD.

Do people with social anxiety (SA) benefit from positive memory retrieval that heightens self-relevant meaning? In this preregistered study, an analog sample of 255 participants with self-reported clinically significant symptoms of SA were randomly assigned to retrieve and process a positive social-autobiographical memory by focusing on either its self-relevant meaning (deep processing) or its perceptual features (superficial processing). Participants were then socially excluded and instructed to reimagine their positive memory. Analyses revealed that participants assigned to the deep processing condition experienced significantly greater improvements than participants in the superficial processing condition in positive affect, social safeness, and positive beliefs about others during initial memory retrieval and in negative and positive beliefs about the self following memory reactivation during recovery from exclusion. These novel findings highlight the potential utility of memory-based interventions for SA that work by “hooking” self-meaning onto recollections of positive interpersonal experiences that elicit feelings of social acceptance.

Social anxiety disorder (SAD) is characterized by persistent anxiety or avoidance of social situations because of a fear of negative evaluation. Cognitive behavioral therapy (CBT) (typically with an exposure component) is a first-line treatment for social anxiety, but there remains room for improvement with regard to treatment efficacy. Therefore, the field continues to better understand the mechanisms underlying SAD and its common and complex comorbidities in order to develop targeted interventions to improve symptom outcomes. Additionally, efforts are under way to improve the efficacy and accessibility of CBT. This review outlines major advances in understanding and treating SAD in adults over the past roughly 3 years (2019 to early May 2022). Themes are identified and discussed, as are recommendations for future research.

Despite their apparent implications for social functioning, adult attachment styles have never been specifically explored among persons with social anxiety disorder. In the current study, a cluster analysis of the Revised Adult Attachment Scale (N. L. Collins, 1996) revealed that 118 patients with social anxiety were best represented by anxious and secure attachment style clusters. Members of the anxious attachment cluster exhibited more severe social anxiety and avoidance, greater depression, greater impairment, and lower life satisfaction than members of the secure attachment cluster. This pattern was replicated in a separate sample of 56 patients and compared with the pattern found in 36 control participants. Social anxiety mediated the association between attachment insecurity and depression. Findings are discussed in the context of their relevance to the etiology, maintenance, and cognitive–behavioral treatment of social anxiety disorder.

Objective: The study represents a conceptual replication of the study by Eng et al. (2001) in a sample of adult patients diagnosed with social anxiety disorder as primary diagnosis. Methods: Two different attachment questionnaires (Bielefeld Questionnaire of Client Expectations (BQCE) and Experiences in Close Relationships (ECR-RD)) were applied to examine whether the effect of attachment on depression (measured by the BDI) is mediated by social anxiety (measured by the LSAS) in a cross-sectional study. Results: The data confirms such a mediation. The effect of attachment measured with the BQCE on depression was completely mediated, whereas the effect of both scales of the ECR-RD (attachment related avoidance and anxiety) on depression was only partially mediated by social anxiety disorder. Conclusion: The study supports the association of attachment, social anxiety, and depressive symptoms and the need to consider different perspectives on attachment.

This therapist guide is designed to give mental health professionals the necessary tools to assess and treat a broad range of mood disorders, particularly depression. Based on the principles of cognitive-behavioral therapy, the ‘Taming the BEAST (TTB)’ program helps patients develop a set of coping strategies and skills to proactively manage their depressed mood. Using the acronym BEAST, treatment modules address biology, emotions, activity, situations, and thoughts. Each module comes complete with step-by-step instructions for delivering treatment including outlines and lists of materials needed. In-session exercises as well as home assignments help motivate the patient and allow for the monitoring of progress. Written by experts in the field, this guide comes complete with chapters on assessment, socialization, and termination. The TTB program offers both therapist and patient a roadmap for overcoming depression.

This chapter builds on the first two steps of cognitive restructuring that were developed in chapter 5: (a) the identification of automatic thoughts (ATs) and the emotions they cause and (b) the identification of thinking errors. This chapter presents the remaining steps in cognitive restructuring: (c) challenging ATs by using disputing questions and (d) generating rational responses. The session opens with a review of the Social Anxiety Session Change Index and homework, and then each concept is covered. There is also a brief discussion in anticipation of the first exposure in the next session. The first in-session exposure is a key moment in treatment.

The present study aims to evaluate the efficacy of Trial-Based Cognitive Therapy (TBCT), a new cognitive-behavioral therapy approach, for generalized social anxiety disorder (GSAD) in a population with high rates of comorbid disorders, especially depression. This two-arm randomized clinical trial included 39 adults (TBCT = 18; waitlist group = 21) diagnosed with GSAD. The TBCT group received 16 weekly sessions of individual TBCT. Symptom severity was assessed at pre- and post-treatment. Participants in the TBCT group showed reduction in social anxiety, social avoidance, and depression, all associated with a large effect size. No differences between pre- and post-treatment scores were observed in the waitlist condition. Results also showed that comorbidity significantly moderated treatment efficacy. Patients with comorbid conditions showed greater reductions in social anxiety symptoms across treatment than those with SAD only. In summary, TBCT was effective in reducing social anxiety and depressive symptoms, particularly for patients with comorbidity.

Background/Objective: Lower levels in well-being have been observed in individuals with Major Depression (MDD) and Social Phobia (SP), but well-planned direct comparisons with control individuals, not suffering from a mental disorder, are lacking. Furthermore, MDD is highly comorbid with anxiety disorders, and SP with depressive disorders. This study is among the first to examine differences in well-being in individuals with a clinical diagnosis of MDD or SP compared to individuals with no such diagnosis and to test differences in well-being within the combined diagnostic categories respective with and without anxiety-depressive comorbidity. Method: Participants were 119 individuals with a diagnosis of MDD, 47 SP and 118 controls. Results: Results revealed that overall well-being as well as emotional, psychological, and social well-being were lower in the MDD and SP group compared to the control group. Individuals with comorbidity reported lower well-being than individuals without comorbidity. Conclusions: These findings have clinical implications as presence of comorbidity may require a different therapeutic approach than with no comorbidity.

The co-occurrence of social anxiety and depression is associated with increased functional impairment and a more severe course of illness. Social anxiety disorder is unique among the anxiety disorders in sharing an affective profile with depression, characterized by low levels of positive affect (PA) and high levels of negative affect (NA). Yet it remains unclear how this shared affective profile contributes to the covariation of social anxiety and depressive symptoms. We examined whether self-reported PA and NA accounted for unique variance in the association between social anxiety and depressive symptoms across three groups (individuals with remitted bipolar disorder, type I [BD; n = 32], individuals with remitted major depressive disorder [MDD; n = 31], and non-psychiatric controls [n = 30]) at baseline and follow-ups of six and 12 months. Low levels of PA, but not NA, accounted for unique variance in both concurrent and prospective associations between social anxiety and depression in the BD group; in contrast, high levels of NA, but not PA, accounted for unique variance in concurrent and prospective associations between social anxiety and depression in the MDD group. Limitations include that social anxiety and PA/NA were assessed concurrently and all measurement was self-report. Few individuals with MDD/BD met current diagnostic criteria for social anxiety disorder. There was some attrition at follow-up assessments. Results suggest that affective mechanisms may contribute to the high rates of co-occurrence of social anxiety and depression in both MDD and BD. Implications of the differential role of PA and NA in the relationship between social anxiety and depression in MDD and BD and considerations for treatment are discussed.

This Special Issue of Cognition and Emotion addresses one of the cardinal concerns of affective science, which is overlapping and distinctive features of anxiety and depression. A central finding in the study of anxiety and depression is that they are moderately highly correlated with each other. This leads us to the question: What is behind this co-occurrence? Possible explanations relate to poor discriminant validity of measures; both emotional states are associated with negative affect; stressful life events; impaired cognitive processes; they share a common biological/genetic diathesis. However, despite a set of common (nonspecific) features, anxiety and depression are clearly not identical emotional states. Differences between them might be best viewed, for example, through their heterogeneous and multi-layered nature, adaptive functions and relations with regulatory processes, positive affect, and motivation or complex cognitive processes. In this introduction we consider several approaches (e.g. functional approach; tripartite model and content-specificity hypothesis) to which most research in this Special Issue is relevant. In addition, we have asked contributors to this Special Issue to indicate how their own studies on comparisons between anxiety and depression and models on anxiety and depression move this area of research to more mature science with applicability.

Age-of-onset has been found to be a marker of clinical relevant subtypes in various medical and psychiatric disorders. In addition, clinical importance of age-of-onset has been reported in Generalized Anxiety Disorder (GAD) but in research to date, arbitrary cut-off ages have been used. In this study, admixture analysis was used to determine the best fitting model of age-of-onset distribution in GAD. Data were derived from the Netherlands Study of Depression and Anxiety (NESDA), including 459 participants with a 6-month diagnosis of GAD, aged 18-65 years. The associations between age-of-onset, identified by admixture analysis, and socio-demographics, clinical factors and vulnerability factors were examined using univariate tests and multivariate logistic regression analyses. Two distributions of age-of-onset were identified, with a cut-off age of 24 years. Multivariate analysis showed that early-onset GAD was associated with being female (OR 2.1 (95%CI 1.4-3.2)), higher education (OR 1.1 (95%CI 1.0-1.2)) and higher neuroticism (OR 1.4 (95%CI 1.1-1.7)), while late-onset GAD was associated with somatic illnesses (OR 1.3 (95%CI 1.1-1.7)). Notably, because age-of-onset was assessed retrospectively, recall bias may have been present. In addition, older persons were not included in NESDA, thus we were unable to detect a possible GAD subtype with very-late-onset. To conclude, GAD disorder is characterized by a bimodal age-of-onset, with an objectively determined early age-of-onset cut-off at 24 years. In GAD, early age-of-onset appeared to be of different origin but this did not imply a more severe subtype as compared to older age-of-onset. Future research should use 24 years as the cut-off for early age-of-onset GAD to more accurately determine the clinical relevance of treatment efficacy and course.

This meta-analysis investigated the efficacy of technology-assisted interventions for individuals with social anxiety disorder (SAD). A systematic literature search in the databases Medline, PsychInfo, and Web of Science revealed 37 randomized controlled trials (2991 participants) that were grouped into internet delivered cognitive behavior therapy (ICBT; 21 trials), virtual reality exposure therapy (VRET; 3 trials), and cognitive bias modification (CBM; 13 trials). Patients undergoing ICBT and VRET showed significantly less SAD symptoms at postassessment than passive control conditions (g = 0.84 and 0.82, respectively). Compared to active control conditions, ICBT had a small advantage (g = 0.38) and VRET showed comparable effects (p > .05). CBM was not more effective than passive control conditions, except when delivered in the laboratory (g = 0.35). While the efficacy of CBM was limited, substantial evidence for ICBT and preliminary evidence for VRET suggests that both can effectively reduce SAD symptoms indicating the potential of technology-assisted interventions for SAD.
