Effectiveness of cognitive-behavioral treatment for panic disorder versus treatment as usual in a managed care setting: 2-year follow-up

Adapting cognitive-behavioral therapy for a Malaysian muslim

Background: Over the years, cognitive-behavioural therapy (CBT) has gained momentum because of its robust evidence in the treatment of several disorders. However, there is an issue of religious and cultural appropriateness as CBT principles are based on Western conceptualization. This single-case study (N = 1) implements a culturally and religiously adapted CBT on a 34-year-old male with panic disorder with agoraphobia in Malaysia. The client had symptoms comprising various episodes of sudden onset of breathlessness, accelerated heart rate, and fear of dying for the last 14 years. The CBT was culturally and religiously adapted based on (1) A CBT manual in Bahasa Malaysia that was previously modified and adjusted according to the norms of the Malaysian society and (2) General guidelines in "Religious-Cultural Psychotherapy in the Management of Anxiety Patients" by Razali et al in 2002. The present modified CBT had 3 assessments formulation sessions and 12 intervention sessions. Methods: The first 6 sessions were based on the behaviour component of CBT (ie, a relaxation technique using Islamic prayer, reciting verses from the Holy Quran, slow breathing exercise, body scan, and progressive muscular relaxation). However, sessions 7 to 12 were focused on cognitive restructuring and exercises, such as identification of negative automatic thoughts, cognitive distortions, dysfunctional thought records, vertical arrow technique, and the coping statement was practised through collaborative empiricism, while implementing Islamic and cultural elements. The focus of termination sessions was on interoceptive exposure, cognitive rehearsal, and in vivo situational exposure. Results: Beck Anxiety Inventory (BAI) was administered at regular intervals. BAI scores revealed the effectiveness of adapting the intervention. Conclusion: Panic attacks, worry about panic attacks, and anxiety scores reduced remarkably and the client was able to go out of the house, travel independently, and pursue religious/social activities.

Psychological therapies for panic disorder with or without agoraphobia in adults: a network meta-analysis

BACKGROUND

Panic disorder is characterised by the presence of recurrent unexpected panic attacks, discrete periods of fear or anxiety that have a rapid onset and include symptoms such as racing heart, chest pain, sweating and shaking. Panic disorder is common in the general population, with a lifetime prevalence of 1% to 4%. A previous Cochrane meta-analysis suggested that psychological therapy (either alone or combined with pharmacotherapy) can be chosen as a first-line treatment for panic disorder with or without agoraphobia. However, it is not yet clear whether certain psychological therapies can be considered superior to others. In order to answer this question, in this review we performed a network meta-analysis (NMA), in which we compared eight different forms of psychological therapy and three forms of a control condition.

OBJECTIVES

To assess the comparative efficacy and acceptability of different psychological therapies and different control conditions for panic disorder, with or without agoraphobia, in adults.

SEARCH METHODS

We conducted the main searches in the CCDANCTR electronic databases (studies and references registers), all years to 16 March 2015. We conducted complementary searches in PubMed and trials registries. Supplementary searches included reference lists of included studies, citation indexes, personal communication to the authors of all included studies and grey literature searches in OpenSIGLE. We applied no restrictions on date, language or publication status.

SELECTION CRITERIA

We included all relevant randomised controlled trials (RCTs) focusing on adults with a formal diagnosis of panic disorder with or without agoraphobia. We considered the following psychological therapies: psychoeducation (PE), supportive psychotherapy (SP), physiological therapies (PT), behaviour therapy (BT), cognitive therapy (CT), cognitive behaviour therapy (CBT), third-wave CBT (3W) and psychodynamic therapies (PD). We included both individual and group formats. Therapies had to be administered face-to-face. The comparator interventions considered for this review were: no treatment (NT), wait list (WL) and attention/psychological placebo (APP). For this review we considered four short-term (ST) outcomes (ST-remission, ST-response, ST-dropouts, ST-improvement on a continuous scale) and one long-term (LT) outcome (LT-remission/response).

DATA COLLECTION AND ANALYSIS

As a first step, we conducted a systematic search of all relevant papers according to the inclusion criteria. For each outcome, we then constructed a treatment network in order to clarify the extent to which each type of therapy and each comparison had been investigated in the available literature. Then, for each available comparison, we conducted a random-effects meta-analysis. Subsequently, we performed a network meta-analysis in order to synthesise the available direct evidence with indirect evidence, and to obtain an overall effect size estimate for each possible pair of therapies in the network. Finally, we calculated a probabilistic ranking of the different psychological therapies and control conditions for each outcome.

MAIN RESULTS

We identified 1432 references; after screening, we included 60 studies in the final qualitative analyses. Among these, 54 (including 3021 patients) were also included in the quantitative analyses. With respect to the analyses for the first of our primary outcomes, (short-term remission), the most studied of the included psychological therapies was CBT (32 studies), followed by BT (12 studies), PT (10 studies), CT (three studies), SP (three studies) and PD (two studies).The quality of the evidence for the entire network was found to be low for all outcomes. The quality of the evidence for CBT vs NT, CBT vs SP and CBT vs PD was low to very low, depending on the outcome. The majority of the included studies were at unclear risk of bias with regard to the randomisation process. We found almost half of the included studies to be at high risk of attrition bias and detection bias. We also found selective outcome reporting bias to be present and we strongly suspected publication bias. Finally, we found almost half of the included studies to be at high risk of researcher allegiance bias.Overall the networks appeared to be well connected, but were generally underpowered to detect any important disagreement between direct and indirect evidence. The results showed the superiority of psychological therapies over the WL condition, although this finding was amplified by evident small study effects (SSE). The NMAs for ST-remission, ST-response and ST-improvement on a continuous scale showed well-replicated evidence in favour of CBT, as well as some sparse but relevant evidence in favour of PD and SP, over other therapies. In terms of ST-dropouts, PD and 3W showed better tolerability over other psychological therapies in the short term. In the long term, CBT and PD showed the highest level of remission/response, suggesting that the effects of these two treatments may be more stable with respect to other psychological therapies. However, all the mentioned differences among active treatments must be interpreted while taking into account that in most cases the effect sizes were small and/or results were imprecise.

AUTHORS' CONCLUSIONS

There is no high-quality, unequivocal evidence to support one psychological therapy over the others for the treatment of panic disorder with or without agoraphobia in adults. However, the results show that CBT - the most extensively studied among the included psychological therapies - was often superior to other therapies, although the effect size was small and the level of precision was often insufficient or clinically irrelevant. In the only two studies available that explored PD, this treatment showed promising results, although further research is needed in order to better explore the relative efficacy of PD with respect to CBT. Furthermore, PD appeared to be the best tolerated (in terms of ST-dropouts) among psychological treatments. Unexpectedly, we found some evidence in support of the possible viability of non-specific supportive psychotherapy for the treatment of panic disorder; however, the results concerning SP should be interpreted cautiously because of the sparsity of evidence regarding this treatment and, as in the case of PD, further research is needed to explore this issue. Behaviour therapy did not appear to be a valid alternative to CBT as a first-line treatment for patients with panic disorder with or without agoraphobia.

Interpersonal Factors Are Associated with Lower Therapist Adherence in Cognitive-Behavioural Therapy for Panic Disorder

OBJECTIVE

The contributions of disorder severity, comorbidity and interpersonal variables to therapists' adherence to a cognitive-behavioural treatment (CBT) manual were tested.

METHOD

Thirty-eight patients received panic control therapy (PCT) for panic disorder. Trained observers watching videotapes of the sixth session of a 24-session protocol rated therapists' adherence to PCT and their use of interventions from outside the CBT model. Different observers rated patients' behavioural resistance to therapy in the same session using the client resistance code. Interview measures obtained before treatment included the Panic Disorder Severity Scale, the anxiety disorders interview schedule for Diagnostic and Statistical Manual of Mental Disorders (DSM)-IV and the structured clinical interview for DSM-IV, Axis II. Questionnaire measures were the anxiety sensitivity index at intake, and, at session 2, the therapist and client versions of the working alliance inventory-short form.

RESULTS

The higher the patients' resistance and the more Axis II traits a patient had, the less adherent the therapist. Moreover, the more resistant the client, the more therapists resorted to interventions from outside the CBT model. Stronger therapist and patient alliance was also generally related to better adherence, but these results were somewhat inconsistent across therapists. Pretreatment disorder severity and comorbidity were not related to adherence.

CONCLUSIONS

Interpersonal variables, particularly behavioural resistance to therapy, are related to therapists' ability to adhere to a treatment manual and to their use of interventions from outside of the CBT model. Copyright © 2015 John Wiley & Sons, Ltd.

KEY PRACTITIONER MESSAGE

Patients' behavioural resistance to therapy may make it more difficult for cognitive-behavioural clinicians to adhere to a structured treatment protocol and more likely for them to borrow interventions from outside the CBT model. Patients' Axis II traits may make adherence to treatment CBT protocol more difficult, although whether this is true varies across therapists. Therapists' adherence to a structured protocol and borrowing from outside of the CBT model do not appear to be affected by disorder severity or Axis I comorbidity.

Applying Group Cognitive Behavioral Therapy for Anxiety Disorders in Community Settings: Retention, Outcome, and Clinical Considerations

The efficacy, and to a lesser extent, effectiveness, of individual cognitive behavioral therapy (CBT) for anxiety disorders has been demonstrated, but whether manualized treatments work in a group format in community settings is less established. We investigated the predictors of retention and outcome in 26 groups (11 Generalized Anxiety Disorder, 11 Panic, 4 Social Phobia groups), conducted for more than 10 years in a semirural community mental health center by 19 therapists. Members of the Anxiety Disorders Treatment Team delivered manualized group CBT treatments. Analysis of standard symptom measures at pre- and posttreatment and archival data revealed significant pre–post decreases in anxiety, retention rates comparable to past findings on group retention, and several significant predictors of retention and outcome. Manualized group CBT for anxiety appears to be a viable treatment in community settings. Limitations of the study as well as related practice–research implications of the findings are discussed.

Personality subtypes in adolescents with panic disorder

This study examined personality subtypes of adolescents diagnosed with Panic Disorder (PD). As part of an NIMH-funded study of adolescent personality and its relation to psychopathology, randomly selected experienced licensed psychologists and psychiatrists used a Q-sort instrument to describe adolescents in their care, of whom 57 had been diagnosed with PD. Q-factor analysis yielded three personality subtypes: High Functioning/Dysphoric, Emotionally Dysregulated, and Avoidant. The subtypes differed on axis I and II pathology, adaptive functioning, and developmental and family history variables. Personality constellations showed substantial incremental validity in predicting adaptive functioning above and beyond DSM-IV axis I diagnoses. The results resemble subtypes recently identified in adults and suggest that adolescents who present with panic symptoms are a heterogeneous group, whose personality needs to be considered in understanding and helping them clinically.

Empirically supported treatments for panic disorder

This article provides an empirical review of the elements and efficacy of both pharmacologic and psychosocial treatments for panic disorder. Both monotherapies and combination treatment strategies are considered. The available evidence suggests that both cognitive behavioral therapy (CBT) and pharmacotherapy (prominently, selective serotonin reuptake inhibitors or serotonin-norepinephrine reuptake inhibitors) are effective first-line agents and that CBT offers particular cost efficacy relative to both pharmacotherapy alone and combined pharmacotherapy and CBT. Predictors of non-response and mechanisms of action are considered, as are novel treatment strategies, including the use of memory enhancers to improve CBT outcome.

Cognitive behavior therapy in the treatment of panic disorder

BACKGROUND

Comprehensive cognitive behavior therapies have been proved to be more effective than behavioral interventions. However, the efficacy of CBT is not studied in the Indian context and also, the amount of change brought about by CBT is not known.

AIMS

This study aims to examine the efficacy of cognitive behavioral intervention (CBI) in the treatment of panic disorder. Our specific objectives were to assess the effectiveness of CBI in reducing symptom severity as well as cognitions related to panic and panic-related behaviors.

DESIGN

The study adopted a two-group comparison with pre- and postassessments design.

MATERIALS AND METHODS

The sample consisted of 30 patients sequentially allotted to the CBI (n = 15) and behavioral intervention (BI, n = 15) groups. Assessment was done using a semistructured interview schedule, panic disorder severity scale, Texas panic attack record form, Anxiety Sensitivity Index, Agoraphobic cognitions questionnaire, Behavioral avoidance checklist, and Panic appraisal inventory. The CBI group was provided with comprehensive cognitive behavior therapy and the BI group with psycho-education and applied relaxation.

RESULTS

CBI was found to be superior to BI in the reduction of panic symptoms, behavioral avoidance, safety behaviors, and cognitions. A large percentage of the CBI group patients met the criteria for clinically significant change with a large magnitude of change.

CONCLUSION

Multicomponent CBI is superior to BI in terms of the amount of change it brings about with respect to panic symptoms, avoidance, safety behaviors, and cognitions.

Treatment of panic disorder: recent developments and current status

Panic disorder is a commonly encountered condition in general medical practice and in various medical settings. It is important for all medical practitioners to be able to recognize this disorder, provide patients with basic information and medical advice, and depending on the specific circumstances, to refer patients for appropriate treatment by primary care physicians, psychiatrists and/or clinical psychologists. This article reviews the developments in the treatment of panic disorder, focusing on the major treatment modalities of pharmacotherapy and cognitive-behavior therapy, as well as their combinations. In addition to providing information on current treatments for panic disorder and the main underlying treatment issues, the article identifies areas where improvements need to be made and areas where much research has been conducted in recent years. These include simplified modes of delivery of cognitive-behavior therapy, optimal ways of combining medications with cognitive-behavior therapy, and minimizing the risk of recurrence after the cessation of treatment.

Dissemination of Cognitive Therapy for Panic Disorder in Primary Care

This study investigated whether brief training in cognitive therapy for panic disorder (Clark et al., 1994) can improve the outcomes that primary care therapists obtain with their patients. Seven primary care therapists treated 36 patients meeting DSM-IV (APA, 1994) criteria for panic disorder with or without agoraphobia in general practice surgeries. Outcomes for the cohort of patients whom the therapists treated with their usual methods (treatment-as-usual) before the training (N = 12) were compared with those obtained with similar patients treated by the same therapists after brief training and ongoing supervision in cognitive therapy (CT) for panic disorder (N = 24). Treatment-as-usual led to significant improvements in panic severity, general anxiety, and depression. However, only a small proportion (17% of the intent-to-treat sample) became panic free and there was no improvement in agoraphobic avoidance. Patients treated with CT achieved significantly better outcomes on all measures of panic attacks, including panic-free rate (54%, intent-to-treat), and showed significantly greater improvements in agoraphobic avoidance and patient-rated general anxiety. In conclusion, cognitive therapy for panic disorder can be successfully disseminated in primary care with a brief therapist training and supervision programme that leads to significant improvements in patient outcomes.

Does psychotherapy research inform treatment decisions in private practice?

Psychologists in independent practice (N = 591) were surveyed regarding their approach to treatment decisions, specifically the use of research on empirically supported treatments (ESTs) to inform practice. All participants received a case study of a patient with panic disorder, and half were randomly assigned to receive a research summary on evidence-based treatments for panic disorder (cognitive-behavioral therapy and pharmacotherapy). Practitioners reported that they rely primarily on clinical experiences to inform treatment decisions, although they often consult EST literature. Those who received the research summary were significantly more likely to report they would use an EST. These results indicate that providing information about ESTs can impact practice. Although this sample was more positive about EST research than clinicians are often depicted to be, this study indicates an enduring research-practice gap in clinical psychology.
