Effects of psychotherapy on comorbid conditions in generalized anxiety disorder

Treating anxiety comorbidity: Lessons from exposure generalization studies

Comorbidity is a characteristic hallmark of anxiety disorders. Presence of comorbid anxiety and depression is challenging to the diagnosis and treatment. Conventional and transdiagnostic treatment options for anxiety disorders strongly depend on the use of exposure. Recent compelling evidence suggests that the beneficial effects of exposure therapy are transferable across different fear- and anxiety provoking situations and might even affect depressive symptomatology. We provide an overview of findings on existing studies on generalization of exposure effects to untreated stimuli and depression. Potential mechanisms which contribute to generalization of beneficial exposure therapy effects, such as extinction generalization, mastery-related increases in self-efficacy and underlying neural changes are presented and discussed. Understanding and promoting mechanisms related to exposure therapy efficacy and generalization can expedite and enhance the development of more effective transdiagnostic therapy approaches for comorbid anxiety disorders.

Cannabis use and social anxiety disorder in emerging adulthood: Results from a nationally representative sample

Cannabis use and social anxiety disorder (SAD) are prevalent during emerging adulthood. Previous work has demonstrated that SAD is related to cannabis use in adults; however, less is known about what correlates relate to this association in emerging adults. A subsample of individuals ages 18-25 years old from the NESARC-III (N = 5194) was used to (a) evaluate the association between cannabis use and SAD and (b) examine what correlates may be associated with cannabis use and SAD in emerging adulthood. Weighted cross-tabulations assessed sociodemographics and lifetime psychiatric disorder prevalence estimates among the emerging adult sample. Multinomial logistic regressions examined associations between sociodemographics and psychiatric disorders and four groups (i.e., no cannabis use or SAD; cannabis use only; SAD only; cannabis use + SAD). The prevalence of co-occurring cannabis use and SAD was 1.10%. Being White, a part-time student, or not a student were associated with increased odds of having co-occurring cannabis use + SAD (OR range: 2.26-3.09). Significant associations also emerged between major depressive disorder, bipolar I disorder, generalized anxiety disorder, specific phobia, agoraphobia, and panic disorder and co-occurring cannabis use + SAD (AOR range: 3.03-19.05). Results of this study may have implications for better identifying and screening emerging adults who are at risk of co-occurring cannabis use and SAD.

Health Occupation and Job Satisfaction: The Impact of Psychological Capital in the Management of Clinical Psychological Stressors of Healthcare Workers in the COVID-19 Era

The COVID-19 pandemic greatly impacted global health. Frontline healthcare workers involved in the response to COVID-19 faced physical and psychological challenges that threatened their wellbeing and job satisfaction. The pandemic crisis, alongside pre-existing critical issues, exposed healthcare workers to constant emotional fatigue, creating an increased workload and vulnerability to stress. Maintaining such stress levels increased their levels of anxiety, irritability and loneliness. Evidence shows that the Psychological Capital (PsyCap) was a strong protective factor against these stressors. The aim of this study was to analyze the level of job satisfaction among health workers facing the COVID-19 pandemic. The possible antecedent factors to satisfaction and the role that PsyCap plays in preserving and fostering higher levels of job satisfaction were investigated. A total of 527 healthcare workers from different areas of Italy were recruited for the study. The results revealed that psychological stress factors have a considerable impact on job satisfaction. All four predictors (Stress Vulnerability, Anxiety Symptoms, Loneliness and Irritability) had the potential to decrease job satisfaction. Loneliness had a more significant effect than other factors assessed in this study. Moreover, the results showed how PsyCap could decrease the effects of psychological stressors on job satisfaction. Consistent with previous studies, our findings show that PsyCap could alleviate negative impacts in work-related circumstances.

A pilot trial of a transdiagnostic treatment for emotional disorders-a locally adapted variant of group Unified Protocol (UP) for Chinese adults

There has been increasing interest in transdiagnostic cognitive-behavioral therapy (CBT), which is more cost efficient yet yields similar effect sizes when compared to disorder-specific CBT. The Unified Protocol (UP) for Transdiagnostic Treatment of Emotional Disorders was adapted for Hong Kong Chinese adults with common mental disorders, such as depression and anxiety. It was piloted in community settings and delivered in a group format. Thirty-one Chinese adults (female = 93.5%, mean age = 44 years) with heterogeneous anxiety and depressive disorders were recruited from a number of public-funded community mental health centers in Hong Kong to participate in a pilot trial of a locally adapted variant of UP. Treatment consisted of 14 group sessions plus one individual session. Each group included six to nine participants. The diagnostic and outcome measures included Anxiety Disorders Interview Schedule for DSM-IV, The Chinese versions of Beck Depression Inventory-Revised (C-BDI-II), Beck Anxiety Inventory (C-BAI), Positive Affect subscale of Positive and Negative Affect Scale, and Work and Social Adjustment Scale. Results indicate significant improvement across a number of outcome measures, with moderate-to-large effect sizes for measures of depression (d = 1.11), anxiety (d = 0.67), positive affect (d = 0.54), and work and social functioning (d = 0.49). Furthermore, 45.2% and 29.0% of the participants scored within the normal range of C-BDI-II and C-BAI at posttreatment, respectively, compared to 3.2% and 6.5% at pretreatment. This pilot, uncontrolled trial demonstrated potential effectiveness of a locally adapted variant of group UP for Chinese adults with common mental disorders. It achieved comparable effect sizes to those observed in western populations.

On the efficacy of the unified protocol for transdiagnostic treatment of emotional disorders: A systematic review and meta-analysis

In recent years a large array of treatment protocols conceptualized as transdiagnostic have been developed with clinical and practical advantages compared to traditional single-disorder protocols. Within this panorama, the Transdiagnostic Unified Protocol (UP) of Emotional Disorders was developed aimed at treating the negative affective processes underlying several diagnostic categories, and accounting for the covariance of different emotional disorders. The UP has been found to efficiently target the roots of these disorders leading to a reduction in symptoms of co-occurring disorders. However, several questions have marginally addressed in the previous studies, and some UP features still remain unexplored. The present meta-analysis aims at evaluating whether the UP results to significant changes in anxiety and depression symptoms severity in children, adolescents, and adults. 19 RCTs and 13 uncontrolled pre-post trials comprising 2183 patients/clients met inclusion criteria for meta-analysis. Large to moderate combined overall effect size for both depression plus anxiety were detected in the uncontrolled pre-post studies (g = 0.756) and in RTCs studies (g = 0.452), respectively. Large effect size at pre-treatment to 3-6-month follow-up was observed for combined depression plus anxiety (g = 1.113). Subgroup analysis suggested that UP treatment does not differ across the anxiety and depression self-report measures. Moreover, UP intervention outperformed both passive and active control conditions to treat negative affective syndromes. Meta-regression confirmed the moderate effects of therapist level of experience, the sample characteristics, and the UP-protocol adaptations. The findings indicate that the manualized UP treatment has potential to contribute to improving mental health outcomes, particularly of anxiety and depression.

Cognitive behavioral therapy for childhood anxiety disorders: What happens to comorbid mood and behavioral disorders? A systematic review

BACKGROUND

High rates of comorbidity among children and adolescents with anxiety disorders are widely documented. To date the question of what happens to comorbid disorders upon treatment of the primary anxiety disorder has received little attention and the optimal treatment strategy for cases with comorbidity remains to be determined.

OBJECTIVES

This review examines the literature on the impact of disorder-specific CBT on comorbid mood and behavioral disorders in young people with a primary anxiety disorder.

SEARCH METHODS

PsycINFO, EMBASE, MEDLINE and the Cochrane Library were systematically searched using predefined selection criteria. Two reviewers independently assessed the relevance of studies, obtained data using a data extraction form and undertook methodological quality analysis.

RESULTS

Ten studies (1647 children in total) were included in the review. All studies demonstrated positive outcomes for CBT focused on the primary anxiety disorder on untargeted comorbid mood and/or externalising disorders.

CONCLUSIONS

Findings suggest CBT focused on the primary anxiety disorder successfully reduces comorbid mood and/or behavioral diagnoses and symptoms of these co-occurring clinical diagnoses. Therefore, the implementation of disorder-specific CBT for the primary disorder is a valid alternative to transdiagnostic interventions and is recommended in cases of comorbidity in children and adolescents with a primary anxiety disorder.

Effects of Acceptance and Commitment Therapy on Impulsive Decision-Making

This study examined the transdiagnostic effect of acceptance and commitment therapy (ACT) on impulsive decision-making in a community sample. A total of 40 adults were randomized to eight individual sessions of ACT or an inactive control. Participants completed pre-, mid-, and post-assessments for psychological symptoms; overall behavior change; valued living; delay discounting; psychological flexibility; and distress tolerance. Data were analyzed with multilevel modeling of growth curves. Significant interaction effects of time and condition were observed for psychological flexibility, distress tolerance, psychological symptoms, and the obstruction subscale of valued living. No significant interaction effect was found for two delay discounting tasks nor the progress subscale of valued living. The ACT condition had a significantly larger reduction of problem behavior at post-assessment. The results support use of ACT as a transdiagnostic treatment for impulsive behaviors. The lack of change in delay discounting contrasts previous research.

The Psychometric Properties and Clinical Utility of the Korean Version of GAD-7 and GAD-2

Generalized anxiety disorder (GAD) is a common but serious form of anxiety disorder. Despite this, the rate of GAD recognition in primary care remains low in both Western and Eastern countries. The GAD-7 and GAD-2 were developed to efficiently identify people with GAD, and their reliability and validity have been well-documented in Western countries. The GAD-7 and GAD-2 have also been widely utilized to screen for other anxiety disorders; however, their diagnostic utility has not been fully justified with empirical support, especially in East Asian samples. In this study, we examined the diagnostic sensitivity and specificity of these screening tools for identifying individuals with GAD or other anxiety disorders, and recommended screening cutoff scores for GAD and other anxiety disorders for use in Korea. Based on the rigorous standard suggested by the Quality Assessment of Diagnostic Accuracy Studies-2, a total of 1,157 participants randomly recruited from the community completed the GAD-7, GAD-2, and other anxiety and depression measures in a counter-balanced order. All participants were assessed, and their psychiatric diagnosis confirmed through a structured clinical interview conducted by independent clinicians blinded to the results of the self-report questionnaires. The GAD-7 and GAD-2 both showed excellent reliability and validity. Notably, both the GAD-7 and GAD-2 demonstrated acceptable diagnostic accuracy in detecting GAD with similar recommended cut-off scores as those reported in Western countries, but unacceptable diagnostic accuracy for other anxiety disorders. We conclude that given their brevity, the GAD-7 and GAD-2 can be well-utilized to identify people with GAD for preventative evaluation and treatment in Korea. Use of the GAD-7 and GAD-2 for screening other anxiety disorders should be cautioned.

The role of self-esteem in Internet addiction within the context of comorbid mental disorders: Findings from a general population-based sample

BACKGROUND AND AIMS

Internet Addiction (IA) has consistently been related to comorbid psychiatric disorders and lowered self-esteem. However, most studies relied on self-report questionnaires using non-representative samples. This study aims to analyze the relative impact of self-esteem and comorbid psychopathology with lifetime IA in a population-based sample of excessive Internet users using clinical diagnoses assessed in a personal interview.

METHODS

The sample of this study is based on a general population survey. Using the Compulsive Internet Use Scale, all participants with elevated Internet use scores were selected and invited to a follow-up interview. Current DSM-5 criteria for Internet gaming disorder were rephrased to apply to all Internet activities. Out of 196 participants, 82 fulfilled the criteria for IA. Self-esteem was measured with the Rosenberg's Self-Esteem Scale.

RESULTS

Self-esteem is significantly associated with IA. For every unit increase in self-esteem, the chance of having IA decreased by 11%. By comparison, comorbidities such as substance-use disorder (excluding tobacco), mood disorder, and eating disorder were significantly more likely among Internet-addicted than in the non-addicted group. This could not be reported for anxiety disorders. A logistic regression showed that by adding self-esteem and psychopathology into the same model, self-esteem maintains its strong influence on IA.

DISCUSSION AND CONCLUSIONS

Self-esteem was associated with IA, even after adjustment for substance-use disorders, mood disorder, and eating disorder. Self-esteem and psychopathology should be considered in prevention, intervention measures, as well as in the conception of etiological models.

Examining the Synergistic Effects of Two Transdiagnostic Vulnerability Factors in Relation to Anxiety and Depressive Symptoms and Disorders Among Latinos in a Community Health Care Setting

Latinos are one of the fastest growing racial/ethnic population in the United States yet they experience a substantial amount of mental health disparities, such as anxiety and depression, compared with non-Hispanic Whites. The current study examined the interactive effects of rumination and mindful attention on anxiety and depression symptoms among economically disadvantaged Latinos. Participants consisted of 391 Latinos (86.7% female; Mage = 38.8 years [ SD = 11.4]; 95.3% first language Spanish) who attended a community-based primary health care clinic. Results provided support for an interaction effect of rumination with mindful attention in relation to depressive, suicidal, social anxiety, and anxious arousal symptoms as well as number of mood and anxiety disorders. The pattern of findings was consistent across each of these continuous dependent measures such that the highest levels of each affective variable were found for those with a combination of higher rumination and lower mindful attention. Unexpectedly, there was no interaction in relation to the dichotomous outcome of presence of any mood/anxiety diagnosis.

Cognitive-Behavioral Therapy for Children With Anxiety and Comorbid Attention-Deficit/Hyperactivity Disorder

OBJECTIVE

To determine whether comorbid attention-deficit/hyperactivity disorder (ADHD) diagnosis (including subtype) predicts response to cognitive-behavior therapy (CBT) for anxiety in children and to examine change in ADHD symptoms after treatment of primary anxiety.

METHOD

A sample of 842 children 5 to 18 years of age received CBT for a primary anxiety disorder. A subsample of 94 children met criteria for comorbid mild-to-moderate ADHD, mostly consisting of predominantly inattentive (n = 61) and combined (n = 27) subtypes. Outcome was defined as response (change in diagnostic severity) and remission (absence of the primary diagnosis) at each time point (after treatment and 3- and/or 6-month follow-up) and analyzed using linear and logistic mixed models.

RESULTS

Neither ADHD diagnosis nor subtype predicted response or remission rates for children's primary anxiety disorders. Children with ADHD also showed modest yet significant improvements in ADHD symptoms after CBT for anxiety.

CONCLUSION

The present findings support the suitability of manual-based group-based CBT for anxiety treatment in children with nonprimary ADHD. Further research should examine whether the positive outcomes reported can be extended to children with primary or severe ADHD.

Psychotherapy Technique Related to Changes in Anxiety Symptoms With a Transdiagnostic Sample

The current study examined how techniques in a psychodynamic model of therapy (Blagys and Hilsenroth, Clin Psychol Sci Pract. 7, 167-188, 2000) were related to changes in anxiety symptoms across early treatment process among a transdiagnostic sample of patients with primary anxiety disorder, subclinical anxiety disorder, and no anxiety disorder. Secondary analyses examined the use of specific psychodynamic techniques in relation to symptom change. Results revealed that therapists' use of psychodynamic-interpersonal (PI) techniques were significantly and directly related to changes in anxiety symptoms, in line with previous findings (Pitman, Slavin-Mulford, and Hilsenroth, J Nerv Ment Dis. 202, 391-396, 2014). In addition, patients with co-occurring axis I and II disorders demonstrated positive changes in anxiety symptoms regardless of level of PI technique used, whereas patients without co-occurring disorders experienced greater improvement with more PI. Implications for transdiagnostic treatment protocols for anxiety, notably Leichsenring and Salzer's (Psychotherapy 51, 224, 2104) Unified Psychodynamic Protocol for Anxiety Disorders, are discussed in relation to the current findings.

Toward a Unified Treatment for Emotional Disorders: Update on the Science and Practice

Mental health professionals have long been concerned with describing and proscribing a structure around the myriad variations of psychological and emotional distress that are deemed to be disordered. This has frequently been characterized as a conflict between so-called "lumpers" and "splitters"-those who advocate broad categorizations based on overarching commonalities versus those who endeavor toward a highly refined structure emphasizing unique characteristics. Many would argue that with the era of the modern Diagnostic and Statistical Manual of Mental Disorders (DSM-III to DSM-5), a splitting ideology has been dominant despite re-emerging concerns that some groups of diagnoses, particularly disorders of anxiety and other emotions, may be more similar than different. As a result of such concerns, transdiagnostic or unified models of psychopathology have burgeoned. In this review, we describe the work of Barlow, Allen, and Choate (2004), whose invited paper "Toward a Unified Treatment for Emotional Disorders" reignited transdiagnostic perspectives of emotional disorders. We provide an update on the scientific models and evidence-based treatments that have followed in the wake of this 2004 publication, including key areas for future study in the advancement of transdiagnostic and unified treatment of emotional disorders.

Toward a Unified Treatment for Emotional Disorders - Republished Article

Over 40 years of development of cognitive behavioral approaches to treating anxiety and related emotional disorders have left us with highly efficacious treatments that are increasingly widely accepted. Nevertheless, these manualized protocols have become numerous and somewhat complex, restricting effective training and dissemination. Deepening understanding of the nature of emotional disorders reveals that commonalities in etiology and latent structure among these disorders supercedes differences. This suggests the possibility of distilling a set of psychological procedures that would comprise a unified intervention for emotional disorders. Based on theory and data emerging from the fields of learning, emotional development and regulation, and cognitive science, we identify three fundamental therapeutic components relevant to the treatment of emotional disorders generally. These three components include (a) altering antecedent cognitive reappraisals; (b) preventing emotional avoidance; and (c) facilitating action tendencies not associated with the emotion that is dysregulated. This treatment takes place in the context of provoking emotional expression (emotional exposure) through situational, internal, and somatic (interoceptive cues), as well as through standard mood-induction exercises, and differs from patient to patient only in the situational cues and exercises utilized. Theory and rationale supporting this new approach are described along with some preliminary experience with the protocol. This unified treatment may represent a more efficient and possibly a more effective strategy in treating emotional disorders, pending further evaluation.

Prevalence, correlates, comorbidity and severity of generalized anxiety disorder in Singapore

Despite its pervasiveness and associated impairment, generalized anxiety disorder (GAD) remains a poorly recognized disorder. Furthermore, given that GAD has been relatively understudied in Asia, the current study examined the prevalence, correlates and co-morbid conditions of this disorder in a multi-ethnic population of Singapore. Data was utilized from the Singapore Mental Health Study (SMHS), a cross-sectional epidemiological survey conducted among the adult population (n=6616) aged 18 years and above. The Composite International Diagnostic Interview version 3.0 (CIDI v3.0) was used to assess co-morbidity as well as the life-time and 12-month prevalence of disorders. Functional impairment and treatment-seeking behavior were also assessed. The life-time (0.9%) and 12-month (0.4%) prevalence estimates in the current study were found to be lower than those reported in Western populations but comparable to the prevalence estimates found in Asian countries. The relatively lower prevalence rate of GAD in this study suggests the possible role of culture in reporting and manifestation of anxiety symptomatology. The failure of a substantial proportion of individuals to seek treatment despite self-reported impairment was also identified as an area of concern.

Emergence of Transdiagnostic Treatments for PTSD and Posttraumatic Distress

Both theoretical and empirical findings have demonstrated similarities across diagnoses, leading to a growing interest in transdiagnostic interventions. Most of the evidence supporting transdiagnostic treatment has accumulated for depression, anxiety, and eating disorders, with minimal attention given to posttraumatic stress disorder and other reactions to traumatic stressors. Although single-diagnosis protocols are effective for posttraumatic stress disorder (PTSD) and other trauma-related disorders, in principle, transdiagnostic approaches may have beneficial applications within a traumatized population. This paper defines different types of transdiagnostic treatments, reviews transdiagnostic approaches used in related disorders, and discusses their applicability to PTSD. Examples are drawn from existing transdiagnostic treatments in order to provide a framework for the application of such interventions to the field of traumatic stress. Implications for implementation and dissemination are also discussed.

Cognitive-Behavioral Therapy for Comorbid Generalized Anxiety Disorder and Panic Disorder With Agoraphobia

The goal of this study was to evaluate the efficacy of a cognitive-behavioral treatment package for comorbid generalized anxiety disorder (GAD) and panic disorder with agoraphobia (PDA). A single-case, multiple-baseline, across-subjects design was used with 3 primary GAD patients with secondary PDA. The efficacy of the treatment was evaluated with a structured interview, a battery of self-report questionnaires, and daily self-monitoring booklets. Results are promising: At posttreatment, 2 out of 3 participants achieved high endstate functioning and maintained this level at 3-, 6-, and 12-month follow-ups. The 3rd participant also improved but achieved moderate endstate functioning. The strengths and limitations of the treatment are discussed.

Efficacy of Cognitive-Behavioral Therapy for Comorbid Panic Disorder With Agoraphobia and Generalized Anxiety Disorder

The goal of this study was to evaluate the efficacy of cognitive-behavioral therapy for comorbid panic disorder with agoraphobia (PDA) and generalized anxiety disorder (GAD) by combining treatment strategies for both disorders. A single-case, multiple-baseline design across participants was used. Three participants with primary PDA and secondary GAD took part in the study. The efficacy of the treatment was assessed by means of a structured interview, self-administered questionnaires, and daily self-monitoring measures. After treatment, 2 of the 3 participants achieved high end-state functioning and maintained this level of functioning at 3-, 6-, and 12-month follow-ups. The third participant also improved but only reached high end-state functioning at 6-month follow-up. It therefore appears that the combined treatment is relatively effective for PDA–GAD comorbidity. Possible avenues for improving the treatment are suggested.

Effectiveness of Transdiagnostic Cognitive Behaviour Therapy for Anxiety and Depression in Adults: A Systematic Review and Meta-analysis

Background: Transdiagnostic Cognitive Behaviour Therapy (CBT) seeks to identify core cognitive-behavioural processes hypothesized to be important across a range of disorders and to develop a treatment that targets these. This contrasts with standard CBT approaches that are disorder-specific. Proponents of transdiagnostic CBT suggest that it may offer advantages over disorder-specific CBT, but little is known about the effectiveness of this approach. Aims: The review aimed to summarize trial-based clinical and cost-effectiveness data on transdiagnostic CBT for anxiety and depression. Method: A systematic review of electronic databases, including peer-reviewed and grey literature sources, was conducted (n = 1167 unique citations). Results: Eight trials were eligible for inclusion in the review. There was evidence of an effect for transdiagnostic CBT when compared to a control condition. There were no differences between transdiagnostic CBT and active treatments in two studies. We found no evidence of cost-effectiveness data. Conclusions: Quality assessment of the primary studies indicated a number of methodological concerns that may serve to inflate the observed effects of transdiagnostic approaches. Although there are positive signs of the value of transdiagnostic CBT, there is as yet insufficient evidence to recommend its use in place of disorder-specific CBT.

The search for universal transdiagnostic and trans-therapy change processes: Evidence for intolerance of uncertainty

The search for universal processes associated with symptom change across emotional disorders and different forms of psychotherapy offers hope of increased theoretical parsimony and treatment efficiencies. This study investigated whether intolerance of uncertainty (IU) is a universal process by examining whether changes in IU were associated with changes in symptoms across three different cognitive behavior therapy protocols for depression (n=106), social anxiety disorder (n=88), or generalized anxiety disorder (n=62) in a community mental health clinic. IU was associated with reductions in repetitive negative thinking in all treatments, which is consistent with IU being a transdiagnostic and 'trans-therapy' process of change. Changes in IU were also associated with symptom relief in the social anxiety disorder and generalized anxiety disorder groups, but not in the depression group. Implications of these findings are discussed within the broader literature of transdiagnostic approaches to emotional disorders.

The Role of Perspective-Taking on Ability to Recognize Fear

Impairment in the ability to detect certain emotions, such as fear, is linked to multiple disorders and follows a pattern of inter-individual variability and intra-individual stability over time. Deficits in fear recognition are often related to social and interpersonal difficulties but the mechanisms by which this processing deficit might occur are not well understood. One potential mechanism through which impaired fear detection may influence social competency is through diminished perspective-taking, the ability to perceive and consider the point of view of another individual. In the current study, we hypothesized that intra-individual variability in the accuracy of facial emotion recognition is linked to perspective-taking abilities in a well-characterized, non-clinical adult sample. Results indicated that the ability to accurately detect fear in the faces of others was positively correlated with perspective-taking, consistent with initial hypotheses. This relationship appeared to be unique to recognition of fear, as perspective-taking was not significantly associated with recognition of the other basic emotions. Results from this study represent an initial step towards establishing a potential mechanism between some processes of FER and perspective-taking difficulties. It is important to establish the relationship between these processes in a non-clinical adult sample so that we can consider the possibility of a developmental or pathological influence of impoverished perspective-taking on fear perception.

Transdiagnostic cognitive behavioural treatment and the impact of co-morbidity: An open trial in a cohort of primary care patients

BACKGROUND

The development of initiatives to improve access to psychological therapies has been driven by the realization that untreated anxiety and depression are both very common and costly to individuals as well as society. Effective and efficient treatments, mostly in the form of cognitive behavioural therapies (CBT), can be used in ways which enhance their acceptability and accessibility. To date, numbers of group therapies have been developed to improve cost efficiency, but in spite of growing interest in transdiagnostic approaches, group therapies have so far mostly been diagnosis specific.

AIMS

This study is aimed at evaluating a brief transdiagnostic cognitive behavioural group therapy (TCBGT) designed to treat both anxiety and depression among patients in primary care.

METHOD

The participants were 287 adult patients in primary care with diagnoses of depression and/or anxiety disorders. They underwent a 5-week TCBGT. A mixed design ANOVA was used to evaluate differential effects of treatment according to diagnostic groups (anxiety versus depression) and number of diagnoses (co-morbidity).

RESULTS

Pre-post differences were significant and the treatment was equally effective for both anxiety disorders and depression. Number of diagnoses did not affect the outcome.

CONCLUSIONS

The study indicates feasibility of the brief transdiagnostic group therapy for a wide range of mood and anxiety disorders in primary care. The results indicate that low intensity, brief transdiagnostic group therapies may be a feasible way to improve access to psychological therapies for a large number of patients.

Challenges and Successes in Dissemination of Evidence-Based Treatments for Posttraumatic Stress: Lessons Learned From Prolonged Exposure Therapy for PTSD

Posttraumatic stress disorder (PTSD) poses monumental public health challenges because of its contribution to mental health, physical health, and both interpersonal and social problems. Recent military engagements in Iraq and Afghanistan and the multitude of resulting cases of PTSD have highlighted the public health significance of these conditions. There are now psychological treatments that can effectively treat most individuals with PTSD, including active duty military personnel, veterans, and civilians. We begin by reviewing the effectiveness of these treatments, with a focus on prolonged exposure (PE), a cognitive-behavioral therapy (CBT) for PTSD. Many studies conducted in independent research labs have demonstrated that PE is highly efficacious in treating PTSD across a wide range of trauma types, survivor characteristics, and cultures. Furthermore, therapists without prior CBT experience can readily learn and implement the treatment successfully. Despite the existence of highly effective treatments like PE, the majority of individuals with PTSD receive treatments of unknown efficacy. Thus, it is crucial to identify the barriers and challenges that must be addressed in order to promote the widespread dissemination of effective treatments for PTSD. In this review, we first discuss some of the major challenges, such as a professional culture that often is antagonistic to evidence-based treatments (EBTs), a lack of clinician training in EBTs, limited effectiveness of commonly used dissemination techniques, and the significant cost associated with effective dissemination models. Next, we review local, national, and international efforts to disseminate PE and similar treatments and illustrate the challenges and successes involved in promoting the adoption of EBTs in mental health systems. We then consider ways in which the barriers discussed earlier can be overcome, as well as the difficulties involved in effecting sustained organizational change in mental health systems. We also present examples of efforts to disseminate PE in developing countries and the attendant challenges when mental health systems are severely underdeveloped. Finally, we present future directions for the dissemination of EBTs for PTSD, including the use of newer technologies such as web-based therapy and telemedicine. We conclude by discussing the need for concerted action among multiple interacting systems in order to overcome existing barriers to dissemination and promote widespread access to effective treatment for PTSD. These systems include graduate training programs, government agencies, health insurers, professional organizations, healthcare delivery systems, clinical researchers, and public education systems like the media. Each of these entities can play a major role in reducing the personal suffering and public health burden associated with posttraumatic stress.

Change in obsessive-compulsive symptoms mediates subsequent change in depressive symptoms during exposure and response prevention

OBJECTIVE

The current study examines the temporal relationship between changes in obsessive-compulsive symptoms and changes in depressive symptoms during exposure and response prevention (EX/RP) therapy for obsessive-compulsive disorder (OCD).

METHOD

Participants were 40 adults (53% female) who received EX/RP in a randomized controlled trial comparing serotonin reuptake inhibitor (SRI) augmentation strategies. Participants completed clinician-administered assessments of OCD (Yale-Brown Obsessive Compulsive Scale) and depressive symptoms (Hamilton Depression Rating Scale) every four weeks from baseline to 32-week follow-up.

RESULTS

Lagged multilevel mediational analyses indicated that change in OCD symptoms accounted for 65% of subsequent change in depressive symptoms. In contrast, change in depressive symptoms only partially mediated subsequent change in OCD symptoms, accounting for 20% of the variance in outcome.

CONCLUSIONS

These data indicate that reductions in co-morbid depressive symptoms during EX/RP for OCD are largely driven by reductions in obsessive-compulsive symptoms.

The utilization of unified protocols in behavioral cognitive therapy in transdiagnostic group subjects: A clinical trial

BACKGROUND

The practicing of protocols based on behavioral cognitive therapy (CBT) have been frequently used in the last decades and adapted to better manage the necessities of patients and providers.

OBJECTIVES

The goal is to build a treatment that is evidence-based - for that reason the unified protocol for multiple emotional disorders (transdiagnostics) have been utilized to simplify treatment - without losing scientific traits. The main goal of this study is to evaluate the unified protocol in groups of patients with depression and anxiety disorders.

MATERIALS AND METHODS

In a pool of 48 subjects, divided in two groups, one was submitted to 12 intervention sessions of the unified protocol while the other was solely given medication. MINI, BAI and BDI were the instruments used at the beginning and at the end of treatment.

RESULTS

The results were highly significant (p<0.001) in as much as with the improvement of anxiety and depressive disorders as it was in the group which was treated with the unified protocol compared with the group which was only given medication

LIMITATIONS

Limitations of this study were the number of sample participants and the non-randomization of subjects in both groups.

CONCLUSION

Group therapy has not been largely implemented though it is deemed very useful for treatments when the unified protocol is used in transdiagnostic patients. Not only does it allow for emotional stabilizing and socialization but it also enables subjects with an altruistic feeling amongst themselves.

Examining psychological inflexibility as a transdiagnostic process across psychological disorders

The current cross-sectional study examined psychological inflexibility, a process in which behavior is rigidly guided by psychological reactions rather than direct contingencies or personal values, as a transdiagnostic process relevant to a range of depressive, anxiety, substance use and eating disorders. A sample of 972 first-year college students between 17 and 20 years of age completed self-report measures of psychological inflexibility and psychological distress as well as a structured diagnostic interview. Psychological inflexibility was significantly higher across a range of current and lifetime depressive and anxiety disorders as well as lifetime history of eating disorders, relative to students with no disorder, even after controlling for general psychological distress. Findings were mixed for substance use disorders, with a more consistent pattern for lifetime history than for current disorders. Psychological inflexibility was also related to having comorbid depressive, anxiety, and substance use disorders relative to only having one of these diagnoses. Results are discussed in relation to research on psychological inflexibility as a transdiagnostic pathological process and target for interventions.

Efficacy of transdiagnostic cognitive behaviour therapy for anxiety disorders: a systematic review and meta-analysis of published outcome studies

Transdiagnostic approaches to cognitive behaviour therapy (TCBT) of anxiety disorders have drawn increasing interest and empirical testing over the past decade. In this paper, we review evidence of the overall efficacy of TCBT for anxiety disorders, as well as TCBT efficacy compared with wait-list, treatment-as-usual, and diagnosis-specific cognitive behaviour therapy (CBT) controls. A total of 11 studies reporting 12 trials (n = 1933) were included in the systematic review. Results from the meta-analysis of 11 trials suggest that TCBT was generally associated with positive outcome; TCBT patients did better than wait-list and treatment-as-usual patients, and treatment gains were maintained through follow-up. The pooled estimate showed a moderate treatment effect, however with large heterogeneity suggesting differences in treatment effects between the studies. Also, all the included trials, apart from one, were judged to be associated with a high risk of bias. Only one study compared TCBT with diagnosis-specific CBT suggesting treatment effect of TCBT to be as strong as diagnosis-specific CBT. This study not only cautiously supports evidence for the efficacy of TCBT, but also suggests the need for more high-quality, large-scaled studies in this area. Transdiagnostic treatments offer great clinical promise as an affordable and pragmatic treatment for anxiety disorders and as a specialized treatment for co-morbid and other-specified anxiety disorders.

Using the GAD-Q-IV to identify generalized anxiety disorder in psychiatric treatment seeking and primary care medical samples

The fourth edition of the Generalized Anxiety Disorder Questionnaire (GAD-Q-IV) is a self-report measure that is commonly used to screen for the presence of generalized anxiety disorder (GAD). The current investigation attempted to identify an optimal cut score using samples obtained from an outpatient psychiatric (n=163) and primary care clinic (n=99). Results indicated that a cut score of 7.67 provided an optimal balance of sensitivity (.85) and specificity (.74) comparable to a previously identified cut score (5.7) across both samples (sensitivity=.90, specificity=.66). However, both cut scores were consistently outperformed by a score representing the criteria for GAD described in the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (sensitivity=.89, specificity=.82).

Clinical relevance of comorbidity in obsessive compulsive disorder: the Netherlands OCD Association study

BACKGROUND

This study describes lifetime and current rates of comorbidity, its onset and its consequences in a large clinical sample of patients with obsessive compulsive disorder (OCD). A wide range of risk factors and clinical characteristics were also examined to determine whether pure OCD is different from OCD with current comorbidity. Finally, the temporal sequencing of the disorders was examined.

METHOD

Data were obtained from the Netherlands Obsessive Compulsive Disorder Association (NOCDA) study. A sample of 382 participants with current OCD (during the past month) was evaluated.

RESULTS

Current comorbidity occurred in 55% of patients with OCD, while 78% suffered from lifetime comorbidity. Comorbidity is associated with more severe OCD, anxiety and depressive symptoms and more negative consequences on daily life. Multiple comorbid disorders often precede OCD and influence both its course and severity. Childhood trauma and neuroticism are vulnerability factors for the development of multiple comorbid disorders in OCD.

LIMITATIONS

It should be noted that causal inferences about the association between risk factors and OCD are precluded since our results were based on cross-sectional data.

CONCLUSION

(Multiple) comorbidity in OCD is clinically relevant since it is associated with a specific pattern of vulnerability, with greater chronicity, with more severe OCD and more negative consequences on daily life. This indicates that the diagnosis and treatment of all comorbid disorders is clinically relevant, and clinicians should be especially aware of multiple disorders in cases of childhood trauma and high levels of neuroticism. Primary OCD has a different developmental and comorbidity pattern compared to secondary OCD.

Effect of transdiagnostic cbt for anxiety disorders on comorbid diagnoses

OBJECTIVE

The present study examines the effectiveness of a 12-week transdiagnostic cognitive-behavioral group in reducing comorbid diagnoses.

METHOD

Data from 79 treatment completers (60.8% women; M age = 32.57 years) during three previous trials of transdiagnostic cognitive behavior therapy (CBT) were examined to compare treatment effects between those with and without comorbid diagnoses. Additionally, rates of remission of comorbid diagnoses were compared to published diagnosis-specific CBT trials.

RESULTS

Results indicate that a majority of clients (64.6%) had at least one comorbid disorder and that those with comorbid diagnoses had higher primary diagnosis severity scores than did those without comorbid diagnoses. The presence of a comorbid diagnosis at pretreatment was not associated with differential improvement in primary diagnosis severity following treatment. Two-thirds of completers with comorbid diagnoses at pretreatment (66.7%) no longer met criteria for a clinically severe comorbid diagnosis at posttreatment, a rate higher than that associated with most trials of diagnosis-specific CBT for anxiety disorders used as benchmarks.

CONCLUSIONS

These results suggest that transdiagnostic cognitive-behavioral group treatment for anxiety may be associated with greater decreases in comorbidity than traditional diagnosis-specific CBT.

Flexible Application of Interoceptive and Situational Exposure-Based Treatment for an Outpatient With Multiple Anxiety and Mood Disorders

Cognitive-behavioral therapy (CBT) is efficacious and effective in the treatment of anxiety disorders. However, few guidelines exist on how to efficiently provide CBT when comorbidity is present. Given that anxiety disorders may share underlying mechanisms of maintenance, targeting such mechanisms may be fruitful when working with individuals who suffer from extensive anxiety-related comorbidity. The present study describes an interoceptive and situational exposure-based treatment with a 40-year-old outpatient whose presentation was complicated by multiple anxiety disorders and related difficulties. A comprehensive assessment monitored mechanisms targeted in treatment, symptoms associated with clinical diagnoses, and related impairment. Treatment gains were clinically and statistically significant. Improvements were maintained 1-month post-treatment. These results add to the growing literature focused on transdiagnostic interventions that successfully target broad-based mechanisms of maintenance for multiple types of psychopathology. Theoretical and technical issues related to this type of intervention are discussed throughout the article.

Randomized clinical trial of cognitive behavioral therapy (CBT) versus acceptance and commitment therapy (ACT) for mixed anxiety disorders

OBJECTIVE

Randomized comparisons of acceptance-based treatments with traditional cognitive behavioral therapy (CBT) for anxiety disorders are lacking. To address this gap, we compared acceptance and commitment therapy (ACT) to CBT for heterogeneous anxiety disorders.

METHOD

One hundred twenty-eight individuals (52% female, mean age = 38, 33% minority) with 1 or more DSM-IV anxiety disorders began treatment following randomization to CBT or ACT; both treatments included behavioral exposure. Assessments at pre-treatment, post-treatment, and 6- and 12-month follow-up measured anxiety-specific (principal disorder Clinical Severity Ratings [CSRs], Anxiety Sensitivity Index, Penn State Worry Questionnaire, Fear Questionnaire avoidance) and non-anxiety-specific (Quality of Life Index [QOLI], Acceptance and Action Questionnaire-16 [AAQ]) outcomes. Treatment adherence, therapist competency ratings, treatment credibility, and co-occurring mood and anxiety disorders were investigated.

RESULTS

CBT and ACT improved similarly across all outcomes from pre- to post-treatment. During follow-up, ACT showed steeper linear CSR improvements than CBT (p < .05, d = 1.26), and at 12-month follow-up, ACT showed lower CSRs than CBT among completers (p < .05, d = 1.10). At 12-month follow-up, ACT reported higher AAQ than CBT (p = .08, d = 0.42; completers: p < .05, d = 0.56), whereas CBT reported higher QOLI than ACT (p < .05, d = 0.42). Attrition and comorbidity improvements were similar; ACT used more non-study psychotherapy at 6-month follow-up. Therapist adherence and competency were good; treatment credibility was higher in CBT.

CONCLUSIONS

Overall improvement was similar between ACT and CBT, indicating that ACT is a highly viable treatment for anxiety disorders.

A Preliminary Investigation of Stimulus Control Training for Worry

For individuals with generalized anxiety disorder, worry becomes associated with numerous aspects of life (e.g., time of day, specific stimuli, environmental cues) and is thus under poor discriminative stimulus control (SC). In addition, excessive worry is associated with anxiety, depressed mood, and sleep difficulties. This investigation sought to provide preliminary evidence for the efficacy of SC procedures in reducing anxiety-, mood-, and sleep-related symptoms. A total of 53 participants with high trait worry were randomly assigned to receive 2 weeks of either SC training (consisting of a 30-min time- and place-restricted worry period each day) or a control condition called focused worry (FW; consisting of instructions to not avoid naturally occurring worry so that worry and anxiety would not paradoxically increase). At post-training, SC was superior to FW in producing reductions on measures of worry, anxiety, negative affect, and insomnia, but not on measures of depression or positive affect. Moreover, SC was superior to FW in producing clinically significant change on measures of worry and anxiety. Results provide preliminary support for the use of SC training techniques in larger treatment packages for individuals who experience high levels of worry.

A randomized clinical trial of transdiagnostic cognitve-behavioral treatments for anxiety disorder by comparison to relaxation training

Transdiagnostic cognitive-behavioral treatments (CBT) for anxiety disorders have been gaining increased attention and empirical study in recent years. Despite this, all of the research on transdiagnostic anxiety treatments to date have either not used a control condition, or have relied on no-treatment or delayed-treatment controls, thus limiting inferences about comparative efficacy. The current study was a randomized clinical trial examining the efficacy of a 12-week transdiagnostic cognitive-behavioral group treatment in comparison to a 12-week comprehensive relaxation training program. Results from 87 treatment initiators suggested significant and statistically equivalent/noninferior outcomes across conditions, although relaxation was associated with a greater rate of dropout despite no differences in treatment credibility. No evidence was found for any differential effects of transdiagnostic CBT for any primary or comorbid diagnoses.

Generalized anxiety disorder: clinical presentation, diagnostic features, and guidelines for clinical practice

Generalized anxiety disorder (GAD) is a prevalent and disabling disorder characterised by persistent worrying, anxiety symptoms, and tension. General practitioners and mental healthcare professionals frequently misdiagnose the presenting symptoms. This article addresses the clinical presentation of GAD and provides guidelines for discriminating GAD from other disorders, based on theoretical considerations and clinical experience. Debate relating to the validity of the definition of GAD is discussed, and suggestions are made for improving the criteria for GAD, which may guide future versions of classification systems such as the Diagnostic and Statistical Manual.

Disorder-specific impact of coordinated anxiety learning and management treatment for anxiety disorders in primary care

CONTEXT

Anxiety disorders commonly present in primary care, where evidence-based mental health treatments often are unavailable or suboptimally delivered.

OBJECTIVE

To compare evidence-based treatment for anxiety disorders with usual care (UC) in primary care for principal and comorbid generalized anxiety disorder (GAD), panic disorder (PD), social anxiety disorder (SAD), and posttraumatic stress disorder (PTSD).

DESIGN

A randomized controlled trial comparing the Coordinated Anxiety Learning and Management (CALM) intervention with UC at baseline and at 6-, 12-, and 18-month follow-up assessments.

SETTING

Seventeen US primary care clinics.

PATIENTS

Referred primary care sample, 1004 patients, with principal DSM-IV diagnoses of GAD (n = 549), PD (n = 262), SAD (n = 132), or PTSD (n = 61) (mean [SD] age, 43.7 [13.7] years; 70.9% were female). Eighty percent of the participants completed 18-month follow-up.

INTERVENTIONS

CALM (cognitive behavior therapy and pharmacotherapy recommendations) and UC.

MAIN OUTCOME MEASURES

Generalized Anxiety Disorder Severity Scale, Panic Disorder Severity-Self-report Scale, Social Phobia Inventory, and PTSD Checklist-Civilian Version scores.

RESULTS

CALM was superior to UC for principal GAD at 6-month (-1.61; 95% confidence interval [CI], -2.42 to -0.79), 12-month (-2.34; -3.22 to -1.45), and 18-month (-2.37; -3.24 to -1.50), PD at 6-month (-2.00; -3.55 to -0.44) and 12-month (-2.71; -4.29 to -1.14), and SAD at 6-month (-7.05; -12.11 to -2.00) outcomes. CALM was superior to UC for comorbid SAD at 6-month (-4.26; 95% CI, -7.96 to -0.56), 12-month (-8.12, -11.84 to -4.40), and 18- month (-6.23, -9.90 to -2.55) outcomes. Effect sizes favored CALM but were not statistically significant for other comorbid disorders.

CONCLUSIONS

CALM (cognitive behavior therapy and pharmacotherapy medication recommendations) is more effective than is UC for principal anxiety disorders and, to a lesser extent, comorbid anxiety disorders that present in primary care.

Conceptual background, development, and preliminary data from the unified protocol for transdiagnostic treatment of emotional disorders

Anxiety and mood disorders are common, chronic, costly, and characterized by high comorbidity. The development of cognitive behavioral approaches to treating anxiety and mood disorders has left us with highly efficacious treatments that are increasingly widely accepted. The proliferation of treatment manuals targeting single disorders, sometimes with trivial differences among them, leaves the mental health professional with no clear way to choose one manual over another and little chance of ever becoming familiar with most of them, let alone trained to competence in their delivery. Deepening understanding of the nature of emotional disorders reveals that commonalities in etiology and latent structures among these disorders supersedes differences. Based on empirical evidence from the domains of learning, emotional development and regulation, and cognitive science, we have distilled a set of psychological procedures that comprise a unified intervention for emotional disorders. The Unified Protocol (UP) is a transdiagnostic, emotion-focused cognitive behavioral treatment, which emphasizes the adaptive, functional nature of emotions, and seeks to identify and correct maladaptive attempts to regulate emotional experiences, thereby facilitating appropriate processing and extinction of excessive emotional responding to both internal (somatic) and external cues. The treatment components of the UP are briefly outlined. Theory and rationale supporting this new approach are described along with some preliminary evidence supporting its efficacy. Implications for the treatment of emotional disorders using the UP are discussed.

Comorbidity and the treatment of principal anxiety disorders in a naturalistic sample

This study examined the impact of comorbidity on treatment outcome and the effects of cognitive behavioral therapy (CBT) for anxiety and depressive disorders on comorbid disorders in a naturalistic sample of 150 patients presenting to an anxiety disorders clinic. The following results were observed across principal (i.e., most severe) diagnoses. Patients with comorbid anxiety and depressive disorders presented for treatment with higher severity of their principal disorder than patients without comorbidity. However, the presence of comorbidity did not predict dropout or poor treatment response, and patients demonstrated significant improvement in their principal disorders regardless of comorbidity. The frequency of clinically severe and subclinical (i.e., not severe enough to meet diagnostic criteria) comorbid conditions decreased significantly over the course of treatment. The implication of these findings for the classification and treatment of emotional disorders is discussed.

Expectancy/Credibility Change as a Mediator of Cognitive Behavioral Therapy for Generalized Anxiety Disorder: Mechanism of Action or Proxy for Symptom Change?

Examined the mediating effect of changes in expectancy/credibility from sessions 4-7 of 14-session cognitive and behavioral therapy for generalized anxiety disorder (GAD). In 76 adults with primary GAD, we predicted that expectancy/credibility would change significantly from sessions 4-7, that degree of change in expectancy/credibility would predict degree of reliable change at posttreatment, and that changes in expectancy/credibility would mediate the relationship between pretreatment severity and change at posttreatment. In support of the hypotheses, a latent growth model revealed significant increases in expectancy/credibility over the critical period. In addition, baseline GAD severity, expectancy/credibility intercept, and rate of change in expectancy/credibility all positively predicted degree of reliable change at posttreatment. Rate of change in expectancy/credibility during the critical period partially mediated the effect of baseline GAD severity, accounting for 38% of the variance in this relationship. This effect was not accounted for by preceding or concurrently changing anxiety levels.

Psychiatric Symptom Improvement in Women Following Group Substance Abuse Treatment: Results from the Women's Recovery Group Study

The Women's Recovery Group study was a Stage I randomized clinical trial comparing a new manual-based group treatment for women with substance use disorders with Group Drug Counseling. Data from this study were examined to determine whether co-occurring symptoms of depression and anxiety would improve with treatment and whether these improvements would demonstrate durability over the follow-up period. The sample consisted of 36 women (29 WRG, 7 GDC) who were administered self-report and clinician-rated measures of anxiety, depression, and general psychiatric symptoms. Although there were no group differences in psychiatric symptom improvement, analyses demonstrated significant within-subject improvement in depression, anxiety, and general psychiatric symptoms. Symptom reduction was not mediated by changes in substance use. This study demonstrated significant psychiatric symptom reduction that remained durable through 6 month follow-up for women receiving group therapy focused on substance abuse relapse prevention. Reduction in psychiatric symptoms may be an additional benefit of substance abuse group therapy for women.

Diagnostic comorbidity in adults with generalized anxiety disorder: impact of comorbidity on psychotherapy outcome and impact of psychotherapy on comorbid diagnoses

The current study examined the impact of comorbidity on cognitive and behavioral therapies for generalized anxiety disorder (GAD) as well as the impact of these therapies on diagnoses comorbid to GAD. Seventy-six treatment-seeking adults with principal diagnoses of GAD received 14 sessions of therapy. Most (n=46; 60.5%) of the sample had at least one comorbid diagnosis. Although the presence of comorbid diagnoses was associated with greater severity of GAD symptoms at pretreatment, greater severity of comorbid major depression, simple phobia, and social phobia was associated with greater change in symptoms of GAD in response to treatment, with no effect on maintenance of gains during a 2-year follow-up. Further, psychotherapy for principal GAD led to a reduction in number of comorbid diagnoses and in severity of social phobia, simple phobia, and major depression at posttreatment. At 2-year follow-up severity of social and simple phobia remained below pretreatment levels, whereas severity of depression was no longer significantly below pretreatment levels. These results suggest that although people with comorbid disorders enter treatment with more severe GAD symptomatology, they demonstrate greater change, and therefore such comorbidity does not diminish the efficacy of cognitive and behavioral therapies for GAD. In addition, the impact of these treatments for GAD may generalize to reduced severity of simple phobia, social phobia, and major depression; however, gains in severity of major depression are not maintained.

Dissemination of cognitive-behavioral treatments for anxiety disorders: Overcoming barriers and improving patient access

Cognitive-behavioral therapies for anxiety disorders are highly efficacious (e.g., Butler, Chapman, Forman, & Beck, 2006; Deacon & Abramowitz, 2004). These treatments nevertheless remain underutilized and difficult to access for many of the patients who suffer from these conditions (e.g., Norton & Hope, 2005). We identify various barriers to the wide-scale dissemination of these treatments, including those that are applicable to empirically supported treatments more generally (e.g., lack of training opportunities, failure to address practitioner concerns) as well as those that may be relatively specific to CBT for anxiety disorders (e.g., practitioner concerns around using exposure interventions). We offer suggestions for overcoming these barriers, including specific guidance about continued accumulation of a supportive research base, making the appeals that are necessary to obtain required funding and organizational support, and the training of practitioners to deliver these treatments. Advocates of CBT for anxiety disorders will need to demonstrate that these treatments are cost effective, if wide-scale dissemination is to occur. In the United States, advocacy with third party payers will also be necessary. Although providing such steps may prove to be a difficult endeavour, the patients who stand to benefit from this work deserve nothing less.

Balancing fidelity and adaptation in the dissemination of empirically-supported treatments: The promise of transdiagnostic interventions

Assessing treatment fidelity is a core methodological consideration in the study of treatment outcome; it influences both the degree to which changes can be attributed to the intervention and the ability to replicate and disseminate the intervention. Efforts to increase access to evidence-based psychological treatments are receiving unprecedented support; but pressures exist to adapt treatments to service settings, running the risk of compromising fidelity. However, little evidence is available to inform the necessary conditions for the transportation of interventions to service provision settings, and the degree to which fidelity is even evaluated or emphasized in dissemination and implementation programs varies dramatically. Moreover, adaptation is associated with several benefits for dissemination efforts and may address relevant barriers to adoption. A particularly promising strategy for maximizing the benefits of both fidelity and adaptation is the use of transdiagnostic interventions. Such treatments allow for greater flexibility of the pacing and content of treatment, while still providing structure to facilitate testing and replication. Preliminary evidence supports the efficacy of this strategy, which may be particularly conducive to dissemination into service provision settings. At this time, further research is needed to evaluate the relationships among fidelity, adaptation, and outcome, and to determine the potential for transdiagnostic treatments to facilitate dissemination.

Treatment for anxiety disorders: Efficacy to effectiveness to implementation

Anxiety disorders are common, costly and debilitating, and yet often unrecognized or inadequately treated in real world, primary care settings. Our group has been researching ways of delivering evidence-based treatment for anxiety in primary care settings, with special interest to preserving the fidelity of the treatment while at the same time promoting its sustainability once the research is over. In this paper, we describe the programs we have developed and our directions for future research. Our first study evaluated the efficacy of CBT and expert pharmacotherapy recommendations for panic disorder in primary care, using a collaborative care model of service delivery (CCAP). Symptom, disability and mental health functioning measures were superior for the intervention group compared to treatment as usual both in the short term and the long term, although also more costly. In our ongoing CALM study, we have extended our population to include panic disorder, social anxiety disorder, generalized anxiety disorder and posttraumatic disorder, while at the same time utilizing clinicians with limited mental health care experience. In addition to pharmacotherapy management, we developed a computer-assisted CBT that guides both novice clinician and patient, thereby contributing to sustainability once the research is over. We have also incorporated a measurement based approach to treatment planning, using a web-based tracking system of patient status. To date, the computer-assisted CBT program has been shown to be acceptable to clinicians and patients. Clinicians rated the program highly, and patients engaged in the program. Future directions for our research include dissemination and implementation of the CALM program, testing potential alternations to the CALM program, and distance delivery of CALM.
