The effect of comorbid major depressive disorder or bipolar disorder on cognitive behavioral therapy for social anxiety disorder

Untangling the complex relationship between bipolar disorder and anxiety: a comprehensive review of prevalence, prognosis, and therapy

Bipolar disorder (BD) frequently coexists with anxiety disorders, creating complex challenges in clinical therapy and management. This study investigates the prevalence, prognostic implications, and treatment strategies for comorbid BD and anxiety disorders. High comorbidity rates, particularly with generalized anxiety disorder, underscore the necessity of thorough clinical assessments to guide effective management. Our findings suggest that anxiety disorders may serve as precursors to BD, especially in high-risk populations, making early detection of anxiety symptoms crucial for timely intervention and prevention. We also found that comorbid anxiety can negatively affect the course of BD, increasing clinical severity, reducing treatment responsiveness, and worsening prognosis. These complexities highlight the need for caution in using antidepressants, which may destabilize mood. Alternatively, cognitive-behavioral therapy presents a promising, targeted approach for managing BD with comorbid anxiety. In summary, this study provides essential insights for clinicians and researchers, enhancing understanding of BD and anxiety comorbidity and guiding more precise diagnostics and tailored interventions to improve overall patient care.

Hypnotherapy modulating early and late event-related potentials components of face processing in social anxiety

BACKGROUND

Hypnotherapy has a potential role in modulating attention bias to treat social anxiety disorder (SAD). This study aimed to verify whether hypnotherapy can reduce social anxiety by changing attentional bias. The primary objective of our study is to explore the influence of hypnosis on various aspects of attention processes, specifically focusing on how it affects attention bias and social anxiety.

METHODS

This study included 69 participants with SAD who were assigned to three groups based on their scores on the Liebowitz Social Anxiety Scale (LSAS). The experimental group (n = 23) received a hypnosis treatment once a week, for a total of six sessions, while the control group (n = 23) and the baseline group (n = 23) did not receive any treatment. To evaluate whether hypnosis could alleviate SAD and attention bias towards threatening stimuli, we employed questionnaires and an odd-one-out task accompanied by electroencephalography (EEG) recordings.

RESULTS

Under the attention sensitivity conditions, the experimental group exhibited a reduced N170 and LPP at the posttest stage, and a similar N170 and LPP reduction under the attention disengagement conditions. Notably, the symptom improvements were positively correlated with the reduction in N170 and LPP amplitude across conditions.

CONCLUSION

Hypnosis treatment modulates the early face processing and late emotional evaluation of threat-related stimuli in SAD patients. These findings suggest that N170 and LPP are important biomarkers for the treatment of SAD.

Cognitive behavioural therapy for social anxiety disorder in people with bipolar disorder: a case series

BACKGROUND

Social anxiety disorder increases the likelihood of unfavourable outcomes in people with bipolar disorder. Cognitive behavioural therapy (CBT) is the first-line treatment for social anxiety disorder. However, people with bipolar disorder have been excluded from the studies that this recommendation is based on.  METHOD: We completed a case series to obtain initial data on whether CBT is an acceptable, safe, and effective treatment for social anxiety disorder in people with bipolar disorder.

RESULTS

Eleven euthymic participants with bipolar disorder attended up to sixteen treatment and three follow-up sessions of CBT for social anxiety disorder. Participants attended on average 95% of the offered CBT sessions. No adverse events were reported. Participants' mean score on the Social Phobia Inventory decreased from 46.5 (SD 6.6) before the treatment to 19.8 (SD 11.9) at the end of the sixteen-session intervention and further to 15.8 (SD 10.3) by the end of the 3-month follow-up. This degree of improvement is equivalent to the effect observed in studies of CBT for social anxiety disorder in people without severe mental illness.

CONCLUSIONS

This case series provides preliminary evidence that CBT is acceptable, safe, and effective for treating social anxiety disorder in people with bipolar disorder during euthymia. A randomized controlled trial is needed to confirm these findings, and to establish whether treatment for social anxiety disorder improves the course of bipolar disorder.

The effect of cognitive-behavioral group therapy on reducing depression and anxiety in patients with mood disorders: experimental research

Mood disorders are one of the most common psychiatric disorders that manifest as a low mood in depressed people or a high mood in manic people. The cognitive-behavioral therapy group is one of the most effective forms of intervention available for patients with mood disorders. This research aimed to evaluate the effect of cognitive-behavioral group therapy in reducing depression and anxiety in patients with mood disorders.

CASE PRESENTATION

The study was a semi-experimental study with a pretest-post-test design with a control group. The research subjects were 60 patients hospitalized in the psychiatric department of Razi Hospital in Tehran, who were randomly divided into two experimental (N:30) and control (N:30) groups. Both groups took medicine as usual. Before the therapeutic intervention, both groups were evaluated with Beck's depression questionnaire and the Zung anxiety scale. In addition to drug therapy, the experimental group participated in ten sessions of the cognitive-behavioral therapy group, and in the control group, no psychological intervention was performed except for drug therapy. At the end of the nonpharmacological treatment intervention, both groups were evaluated again with the aforementioned tests. The obtained data were analyzed using independent and dependent t-tests.

CLINICAL DISCUSSION

The research findings showed that the cognitive-behavioral therapy group was significantly (P<0.05) effective in reducing the depression of hospitalized patients with mood disorders, but this method did not have much effect in reducing the anxiety of the patients.

CONCLUSION

Cognitive-behavioral group therapy can be effective in reducing depression in hospitalized patients with mood disorders.

PROTOCOL: Effects of virtual reality exposure therapy versus in vivo exposure in treating social anxiety disorder in adults: A systematic review and meta-analysis

This is the protocol for a Campbell systematic review. The objectives are as follows: (a) to quantify the effect sizes for virtual reality exposure therapy (VRET) in the treatment of social anxiety disorder (SAD), targeting primary social anxiety symptoms, comorbid anxiety and depression symptoms and improvements in quality of life, when compared to WL, information control, care-as-usual and placebo; (b) to compare VRET to in vivo cognitive and cognitive-behavioral interventions in treating SAD, at posttest and follow-up, using between-group design; (c) to identify the key features which are linked to beneficial outcomes in the two formats in treating SAD and (d) to collect and interpret information on differences in treatment uptake, adherence and attrition, as well as clinical significance and therapist-time in both treatment formats.

Comorbidity as a moderator of the differential efficacy of transdiagnostic behavior therapy and behavioral activation for affective disorders

OBJECTIVE

Transdiagnostic psychotherapies have been proposed as an effective means for addressing the needs of patients with multiple, comorbid disorders. Yet, it remains unknown whether transdiagnostic approaches empirically outperform disorder-specific psychotherapies for patients with comorbid disorders. Thus, this study tested whether comorbidity moderated the efficacy of transdiagnostic behavior therapy (TBT) and behavioral activation (BA) for patients with various affective disorders.

METHODS

Data derived from a randomized controlled trial in which 93 treatment-seeking veterans received 12 sessions of TBT (n = 46) or BA (n = 47). Baseline comorbidity was assessed with a diagnostic interview. Patients rated their symptoms and functioning throughout treatment, and therapists recorded premature treatment discontinuation.

RESULTS

Multilevel models revealed significant interactive effects on changes in symptoms and functioning, but not on the posttreatment levels of these outcomes; whereas patients with more comorbidity experienced greater reductions in distress and symptom interference in TBT compared to BA, those with one disorder had better outcomes in BA. Similarly, whereas patients with more comorbidity were less likely to prematurely discontinue TBT compared to BA, those with one disorder were less likely to prematurely discontinue BA.

CONCLUSIONS

The results lend empirical support to previously untested hypotheses for potential benefits of transdiagnostic psychotherapies.Trial registration: ClinicalTrials.gov identifier: NCT01947647.

Comorbid depression and treatment of anxiety disorders, OCD, and PTSD: Diagnosis versus severity

BACKGROUND

Although anxiety and depression are highly comorbid disorders, it remains unclear whether and how a concurrent depression affects the outcome of anxiety treatment.

METHOD

Using anonymized routine outcome monitoring (ROM) data of 740 patients having received specialized treatment for an anxiety disorder, OCD, or PTSD, this study investigates whether a comorbid diagnosis of depression and/or self-reported depression severity levels relate to the patients' improvement following anxiety treatment.

RESULTS

The results show that both the patients with and those without comorbid depression had profited similarly from the anxiety, OCD, or PTSD treatment, regardless of whether depression was merely diagnosed prior to treatment or based on self-reported severity (and assuming a smallest effect size of interest of d = 0.35/r = .2). Importantly, the post-treatment reductions in self-reported depressive symptoms were strongly and positively related to the reductions in self-reported anxiety symptoms and disorder-related disability.

LIMITATIONS

Causal inferences cannot be made due to the retrospective cross-sectional design.

CONCLUSIONS

The outcomes obtained in a naturalistic patient sample support current treatment guidelines recommending evidence-based treatment for anxiety disorders, OCD, and PTSD in patients with and without a comorbid depression. Future treatment studies are recommended for investigate the (bi)directionality of anxiety and depressive symptoms throughout treatment.

The effect of depression on treatment outcome in social anxiety disorder: an individual-level meta-analysis

Social anxiety disorder (SAD) is highly comorbid with depression. In the present meta-analysis, we conducted the first individual-level examination of the association between pre-treatment depression and improvement in social anxiety symptoms during treatment. We identified eligible studies on cognitive behavior therapy (CBT) and pharmacotherapy for SAD and contacted authors to obtain individual-level data. We obtained these data from 41 studies, including 46 treatment conditions (n = 4,381). Our results showed that individuals who had high levels of depression at pre-treatment experienced greater decreases in social anxiety symptoms from pre- to post-treatment, but not at follow-up. When analyzing treatment modalities (individual CBT, group CBT, internet-delivered CBT, and pharmacotherapy), we found that depressive symptoms were associated with better post-treatment outcomes for individual CBT and internet-delivered CBT, but not for pharmacotherapy or group CBT. Our findings suggest that depression does not negatively affect treatment outcome in SAD and may even lead to improved outcomes in some treatment formats. Clinical implications of these findings are discussed.

Total Recall: Lateral Habenula and Psychedelics in the Study of Depression and Comorbid Brain Disorders

Depression impacts the lives and daily activities of millions globally. Research into the neurobiology of lateral habenula circuitry and the use of psychedelics for treating depressive states has emerged in the last decade as new directions to devise interventional strategies and therapies. Several clinical trials using deep brain stimulation of the habenula, or using ketamine, and psychedelics that target the serotonergic system such as psilocybin are also underway. The promising early results in these fields require cautious optimism as further evidence from experiments conducted in animal systems in ecologically relevant settings, and a larger number of human studies with improved spatiotemporal neuroimaging, accumulates. Designing optimal methods of intervention will also be aided by an improvement in our understanding of the common genetic and molecular factors underlying disorders comorbid with depression, as well as the characterization of psychedelic-induced changes at a molecular level. Advances in the use of cerebral organoids offers a new approach for rapid progress towards these goals. Here, we review developments in these fast-moving areas of research and discuss potential future directions.

Do depressive symptoms affect the outcome of treatments for SAD? A meta analysis of randomized controlled trials

Individuals with social anxiety disorder (SAD) typically have elevated depressive symptoms. In the present meta-analysis, we reviewed the treatment outcome literature in SAD and examined whether depressive symptoms predict treatment outcome. We focused on randomized controlled trials of cognitive behavior therapy (individual face-to-face, group format, and internet-delivered format) and randomized controlled trials of pharmacotherapy. After implementing exclusion criteria, 108 studies with 133 treatment conditions (n = 12,913 participants) were included in the meta-analysis. Our findings indicated that treatments for SAD were efficacious and significantly reduced social anxiety symptoms across all treatment modalities. Exclusion of individuals with MDD or high levels of depression did not affect outcome at post-treatment or at follow-up. However, we found that elevated depressive symptoms were associated with greater reductions in social anxiety symptoms from pre-treatment to post-treatment. Importantly, this effect was above and beyond pre-treatment levels of social anxiety. Finally, analyzing treatment modalities separately, we found that depressive symptoms were associated with better post-treatment outcomes in individual face-to-face CBT but not in other modalities. Clinical and research implications of these findings are discussed.

Comorbidity in social anxiety disorder: diagnostic and therapeutic challenges

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.

Transdiagnostic Tailored Internet- and Mobile-Based Guided Treatment for Major Depressive Disorder and Comorbid Anxiety: Study Protocol of a Randomized Controlled Trial

Introduction: Depression is highly prevalent and often accompanied by comorbid anxiety disorder. Internet-based interventions have shown to be one effective treatment modality; however, comorbidities are often not targeted. Transdiagnostic tailored internet-and mobile-based interventions (IMIs) might be promising to overcome such issues. Aim: This study aims to evaluate the efficacy, moderators, and cost-effectiveness of a transdiagnostic tailored internet- and mobile-based guided intervention for depression and comorbid anxiety in individuals with major depressive disorder (MDD). Method: Two-hundred participants with MDD will be randomly assigned to an 8-week guided self-help internet intervention (IC) or a 6-month wait-list control group (WLC). Participants of the IC will receive weekly content-focused feedback on module completion as well as monitored adherence reminders from an eCoach. The primary outcome is clinician-rated depression severity (QIDS-C) at post-assessment assessed by diagnostic raters blind to study condition. Secondary outcomes include, e.g., change in diagnostic status (MDD and anxiety disorders), remission and response rates, disorder symptom severity, health related quality of life, incongruence related to needs and values, and behavioral activation. Assessments will take place at baseline (T1), post-assessment (T2), 6-month follow-up (T3), and 12-month follow-up in the IC. Data will be analyzed on an intention-to-treat basis and per protocol. A large number of a priori defined moderators of treatment outcome will be assessed at baseline and tested in predicting treatment outcome. Cost-effectiveness will be evaluated from a societal perspective. Discussion: The present study will provide evidence on the efficacy, potential cost-effectiveness, and moderators of a transdiagnostic tailored guided internet- and mobile-based treatment protocol.

Anxiety disorders and childhood maltreatment as predictors of outcome in bipolar disorder

BACKGROUND

Comorbid anxiety disorders and childhood maltreatment have each been linked with unfavourable outcomes in people with bipolar disorder. Because childhood maltreatment is associated with anxiety disorders in this population, their respective predictive value remains to be determined.

METHODS

In 174 adults with bipolar disorder, we assessed childhood maltreatment using the Childhood Trauma Questionnaire and lifetime anxiety disorders with the MINI International Neuropsychiatric Interview. We constructed an overall index of severity of bipolar disorder as a sum of six indicators (unemployment, psychotic symptoms, more than five manic episodes, more than five depressive episodes, suicide attempt, and hospital admission). We tested the relationship between childhood maltreatment, the number of anxiety disorders and the overall severity index using ordered logistic regression.

RESULTS

The number of lifetime anxiety disorders was associated with the overall severity index (OR = 1.43, 95%CI = 1.01-2.04, p = 0.047). This relationship was only slightly attenuated when controlled for childhood maltreatment (OR = 1.39, 95%CI = 0.97-2.00, p = 0.069). The relationship between childhood maltreatment and the overall severity index was not statistically significant (OR = 1.26, 95%CI = 0.92-1.74, p = 0.151). Secondary analyses revealed that childhood maltreatment was associated with suicide attempts (OR = 1.70, 95%CI = 1.15-2.51, p = 0.008) and obsessive compulsive disorder was associated with the overall severity index (OR = 9.56, 95%CI = 2.20-41.47, p = 0.003).

LIMITATIONS

This was a cross-sectional study with a moderate-sized sample recruited from a specialist program.

CONCLUSIONS

While comorbid anxiety disorders are associated with the overall severity of bipolar disorder, childhood maltreatment is specifically associated with suicide attempts. Clinicians should systematically assess both factors. Interventions to improve outcomes of people with bipolar disorder with comorbid anxiety disorders and history of childhood maltreatment are needed.

Prevalence of current anxiety disorders in people with bipolar disorder during euthymia: a meta-analysis

BACKGROUND

Anxiety disorders are highly prevalent in people with bipolar disorder, but it is not clear how many have anxiety disorders even at times when they are free of major mood episodes. We aimed to establish what proportion of euthymic individuals with bipolar disorder meet diagnostic criteria for anxiety disorders.

METHOD

We performed a random-effects meta-analysis of prevalence rates of current DSM-III- and DSM-IV-defined anxiety disorders (panic disorder, agoraphobia, social anxiety disorder, generalized anxiety disorder, specific phobia, obsessive-compulsive disorder, post-traumatic stress disorder, and anxiety disorder not otherwise specified) in euthymic adults with bipolar disorder in studies published by 31 December 2015.

RESULTS

Across 10 samples with 2120 individuals with bipolar disorder, 34.7% met diagnostic criteria for one or more anxiety disorders during euthymia [95% confidence interval (CI) 23.9-45.5%]. Direct comparison of 189 euthymic individuals with bipolar disorder and 17 109 population controls across three studies showed a 4.6-fold increase (risk ratio 4.60, 95% CI 2.37-8.92, p < 0.001) in prevalence of anxiety disorders in those with bipolar disorder.

CONCLUSIONS

These findings suggest that anxiety disorders are common in people with bipolar disorder even when their mood is adequately controlled. Euthymic people with bipolar disorder should be routinely assessed for anxiety disorders and anxiety-focused treatment should be initiated if indicated.

Secondary depression in transdiagnostic group cognitive behavioral therapy among individuals diagnosed with anxiety disorders

Anxiety and depression co-occur at high rates, and their comorbidity typically creates a more severe clinical presentation then either alone. The effect of comorbid depression appears to vary across anxiety and related disorders. Transdiagnostic treatments present a promising option to improve comorbid conditions by targeting shared factors (e.g., information processing biases). The purpose of this study was to examine the reciprocal effects of secondary depression in transdiagnostic group cognitive behavioral therapy for anxiety (TGCBT). 120 individuals diagnosed with a primary anxiety disorder, 42 of whom had a depressive diagnosis, were enrolled in 12 weeks of TGCBT. Depressed individuals were compared to those without a depressive diagnosis on both clinician-rated and self-reported anxiety and depression following TGCBT. Although depressed individuals scored higher on most indices of anxiety at pre-treatment, both groups improved similarly with some evidence of greater improvement among those with comorbid depression. All individuals improved in self-reported depressive symptoms and comorbid depression improved to subclinical levels. These results posit TGCBT as an effective, efficient option for treating patients with anxiety and comorbid depression.

Internet-delivered transdiagnostic and tailored cognitive behavioral therapy for anxiety and depression: a systematic review and meta-analysis of randomized controlled trials

Anxiety and depressive disorders are often comorbid. Transdiagnostic and tailored treatments seem to be promising approaches in dealing with comorbidity. Although several primary studies have examined the effects of Internet-delivered cognitive behavior therapy (iCBT) for anxiety and depression, no meta-analysis including different types of iCBT that address comorbidity has been conducted so far. We conducted systematic searches in databases up to 1 July 2016. Only randomized trials comparing transdiagnostic/tailored iCBT for adult anxiety and/or depression with control groups were included. Nineteen randomized trials with a total of 2952 participants that met inclusion criteria were analyzed. The quality of the studies was high, however the blinding criteria were not fulfilled. The uncontrolled effect size (Hedges' g) of transdiagnostic/tailored iCBT on anxiety and depression outcomes was large and medium for quality of life. The controlled effect size for iCBT on anxiety and depression outcomes was medium to large (anxiety: g = .82, 95% CI: .58-1.05, depression: g = .79, 95% CI: .59-1.00) and medium on quality of life (g = .56, 95% CI: .37-.73). Heterogeneity was small (quality of life) to moderate (anxiety, depression). There was a large effect on generic outcome measures and a moderate effect on comorbidities. When compared to disorder-specific treatments there were no differences on anxiety and quality of life outcomes, however there were differences in depression outcomes. Transdiagnostic and tailored iCBT are effective interventions for anxiety disorders and depression. Future studies should investigate mechanisms of change and develop outcome measures for these interventions.

Interpersonal Psychotherapy and Cognitive-Behavioral Therapy as an Integrated Treatment Approach for Co-Occurring Bipolar I and Social Anxiety Disorder

Social anxiety disorder (SAD) is frequently comorbid with bipolar disorder (BD), yet frontline pharmacological interventions for SAD are often contraindicated for individuals with BD. We present a case report of a 29-year-old male with Bipolar I Disorder who received cognitive-behavioral therapy (CBT) for SAD, followed by CBT and interpersonal therapy (IPT) for SAD. The patient completed standardized self-report measures of social anxiety and depressive symptoms throughout treatment and at 1-month and 3-month follow-ups. The greatest social anxiety symptom improvement occurred during the CBT phase, and the patient experienced small but additional benefit with the incorporation of IPT techniques. Although not a direct target of treatment, the patient’s depressive symptoms remained subthreshold throughout treatment. Finally, the patient reported significantly higher quality of life at 1-month and 3-month follow-ups, compared with a reference group of BD outpatients. Findings offer preliminary support for the integration of CBT and IPT in treating comorbid SAD among individuals with BD. Clinical implications and suggestions for future research are discussed.

Psychosocial treatment and interventions for bipolar disorder: a systematic review

BACKGROUND

Bipolar disorder (BD) is a chronic disorder with a high relapse rate, significant general disability and burden and with a psychosocial impairment that often persists despite pharmacotherapy. This indicates the need for effective and affordable adjunctive psychosocial interventions, tailored to the individual patient. Several psychotherapeutic techniques have tried to fill this gap, but which intervention is suitable for each patient remains unknown and it depends on the phase of the illness.

METHODS

The papers were located with searches in PubMed/MEDLINE through May 1st 2015 with a combination of key words. The review followed the recommendations of the Preferred Items for Reporting of Systematic Reviews and Meta-Analyses statement.

RESULTS

The search returned 7,332 papers; after the deletion of duplicates, 6,124 remained and eventually 78 were included for the analysis. The literature supports the usefulness only of psychoeducation for the relapse prevention of mood episodes and only in a selected subgroup of patients at an early stage of the disease who have very good, if not complete remission, of the acute episode. Cognitive-behavioural therapy and interpersonal and social rhythms therapy could have some beneficial effect during the acute phase, but more data are needed. Mindfulness interventions could only decrease anxiety, while interventions to improve neurocognition seem to be rather ineffective. Family intervention seems to have benefits mainly for caregivers, but it is uncertain whether they have an effect on patient outcomes.

CONCLUSION

The current review suggests that the literature supports the usefulness only of specific psychosocial interventions targeting specific aspects of BD in selected subgroups of patients.
