Patterns of change during cognitive behavioral treatment for panic disorder

Long-Term Effects of Cognitive-Behavioral Therapy and Yoga for Worried Older Adults

OBJECTIVES

Cognitive-behavioral therapy (CBT) and yoga decrease worry and anxiety. There are no long-term data comparing CBT and yoga for worry, anxiety, and sleep in older adults. The impact of preference and selection on these outcomes is unknown. In this secondary data analysis, we compared long-term effects of CBT by telephone and yoga on worry, anxiety, sleep, depressive symptoms, fatigue, physical function, social participation, and pain; and examined preference and selection effects.

DESIGN

In this randomized preference trial, participants (N = 500) were randomized to a: 1) randomized controlled trial (RCT) of CBT or yoga (n = 250); or 2) preference trial (selected CBT or yoga; n = 250). Outcomes were measured at baseline and Week 37.

SETTING

Community.

PARTICIPANTS

Community-dwelling older adults (age 60+ years).

INTERVENTIONS

CBT (by telephone) and yoga (in-person group classes).

MEASUREMENTS

Penn State Worry Questionnaire - Abbreviated (worry);^1,2 Insomnia Severity Index (sleep);³ PROMIS Anxiety Short Form v1.0 (anxiety);^4,5 Generalized Anxiety Disorder Screener (generalized anxiety);^6,7 and PROMIS-29 (depression, fatigue, physical function, social participation, pain).^8,9 RESULTS: Six months after intervention completion, CBT and yoga RCT participants reported sustained improvements from baseline in worry, anxiety, sleep, depressive symptoms, fatigue, and social participation (no significant between-group differences). Using data combined from the randomized and preference trials, there were no significant preference or selection effects. Long-term intervention effects were observed at clinically meaningful levels for most of the study outcomes.

CONCLUSIONS

CBT and yoga both demonstrated maintained improvements from baseline on multiple outcomes six months after intervention completion in a large sample of older adults.

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.

Rate of improvement during and across three treatments for panic disorder with or without agoraphobia: cognitive behavioral therapy, selective serotonin reuptake inhibitor or both combined

BACKGROUND

Existing literature on panic disorder (PD) yields no data regarding the differential rates of improvement during Cognitive Behavioral Therapy (CBT), Selective Serotonin Reuptake Inhibitor (SSRI) or both combined (CBT+SSRI).

METHOD

Patients were randomized to CBT, SSRI or CBT+SSRI which each lasted one year including three months of medication taper. Participating patients kept record of the frequency of panic attacks throughout the full year of treatment. Rate of improvement on panic frequency and the relationship between rate of improvement and baseline agoraphobia (AG) were examined.

RESULTS

A significant decline in frequency of panic attacks was observed for each treatment modality. SSRI and CBT+SSRI were associated with a significant faster rate of improvement as compared to CBT. Gains were maintained after tapering medication. For patients with moderate or severe AG, CBT+SSRI was associated with a more rapid improvement on panic frequency as compared to patients receiving either mono-treatment.

LIMITATIONS

Frequency of panic attacks was not assessed beyond the full year of treatment. Second, only one process variable was used.

CONCLUSIONS

Patients with PD respond well to each treatment as indicated by a significant decline in panic attacks. CBT is associated with a slower rate of improvement as compared to SSRI and CBT+SSRI. Discontinuation of SSRI treatment does not result in a revival of frequency of panic attacks. Our data suggest that for patients without or with only mild AG, SSRI-only will suffice. For patients with moderate or severe AG, the combined CBT+SSRI treatment is recommended.

Temporal patterns of change in panic disorder during cognitive behaviour therapy: an Indian study

BACKGROUND

CBT has been proven to be effective in the treatment of panic disorder; however, attempts to study the process of change are limited.

AIM

The study evaluated the temporal patterns of change in the panic symptoms, cognitions, behaviours, and anxiety sensitivity in subjects with panic disorder being treated with CBT.

METHOD

Thirty subjects with panic disorder were allocated to two groups: Cognitive Behaviour Therapy (CBT, n = 15) and Behaviour Therapy (BT, n = 15). Assessments were carried out weekly for five consecutive weeks using the Semi-Structured Interview Schedule, the Anxiety Sensitivity Index, the Agoraphobic Cognitions Questionnaire, and the Texas Panic Attack Record Form. The CBT group received comprehensive CBT and the BT group received psycho-education and Applied Relaxation.

RESULTS

Following intervention the change was continuous and gradual on all the variables in the CBT group and the scores reduced to a functional range after 4-5 weeks of therapy. Such a change was not evident in the BT group. Significant change was evident in cognitive domains following the introduction of the exposure and cognitive restructuring within the CBT group. Both cognitive and behavioural techniques contributed to the overall change.

CONCLUSION

CBT had an impact on the cognitive domains and significant changes were evident corresponding to the addition of cognitive restructuring and exposure techniques in the 3rd to 5th week. Both cognitive and behavioural components are therefore crucial for overall improvement to occur.

Do patterns of change during treatment for panic disorder predict future panic symptoms?

BACKGROUND AND OBJECTIVES

Cognitive-behavioral therapies are currently the gold standard for panic disorder treatment, with well-documented treatment response. However, following interventions, some individuals continue to improve, while others experience a return of symptoms. The field lacks reliable ways to predict follow-up symptomatology. In the current study, a cluster analysis with a repeated measures design was conducted to examine change patterns over 12 weeks of cognitive behavioral group therapy for panic disorder. The central aim of the study was to evaluate if change patterns predict level of panic symptom severity at a six month follow-up in this sample.

METHODS

Individuals with panic disorder (N = 36) completed a measure of panic symptoms (Panic Disorder Severity Scale) at the outset of every therapy session and at a six month follow-up.

RESULTS

Results revealed three patterns of change in this specific trial, which significantly predicted level of panic symptoms six months post-treatment, beyond initial or final level of panic symptoms, and beyond total symptom change.

LIMITATIONS

Given the relatively small, lab-based sample, replications in other settings and samples will be important.

CONCLUSIONS

Overall, results provide initial evidence that change patterns are meaningful predictors of panic symptom severity well after the final session of treatment.

Was wirkt in der Kognitiven Verhaltenstherapie der Panikstörung mit Agoraphobie?

Die kognitive Verhaltenstherapie (KVT) hat sich in empirischen Studien als wirksame Behandlungsform von Panikstörungen mit Agoraphobie erwiesen. Zu den zentralen Behandlungskomponenten gehören a) Psychoedukation über Angst und Panik, b) kognitive Interventionen, um die Tendenz zu Missinterpretationen körperlicher Wahrnehmungen zu vermindern, c) interozeptive und in vivo Exposition sowie d) Bewältigungskompetenzen zur Beeinflussung von körperlichen Symptomen, wie beispielsweise Entspannungs- und Atemtechniken. Empirische Befunde zur Effektivität dieser Interventionen werden vorgestellt und abschließend hinsichtlich ihrer Bedeutung im Rahmen einer evidenzbasierten Therapie der Panikstörung mit und ohne Agoraphobie in der Praxis diskutiert.

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.

Critical realism: a way forward for evaluation research in nursing?

BACKGROUND

Critical realism is a relatively new philosophical perspective that combines a realist ontology with a relativist epistemology in subscribing to a form of "robust" relativism. The potential benefits of adopting a critical realist approach are considered in two areas of evaluation research: theory-driven programme evaluation and policy evaluation.

AIM

The aim of the paper is to identify the main features of critical realism and explore its potential as a philosophical framework in the field of evaluation research.

CONCLUSION

We argue that critical realism provides a coherent framework for evaluation research that is based on the understanding of causal mechanisms. This is particularly important for frontline services seeking to use evidence-based interventions, as interventions need to be properly understood if they are to be used effectively in the context of clinical practice. Critical realism can also add depth to policy analysis. However, there is a potential for critical realists to drift beyond the boundary that separates scientific knowledge from speculative theory when making recommendations about the best course of action to follow.

Cognitive-behavioral treatment of late-life generalized anxiety disorder

This study addressed the efficacy of cognitive-behavioral therapy (CBT), relative to minimal contact control (MCC), in a sample of 85 older adults (age 60 years and over) with generalized anxiety disorder (GAD). All participants completed measures of primary outcome (worry and anxiety), coexistent symptoms (depressive symptoms and specific fears), and quality of life. Results of both completer and intent-to-treat analyses revealed significant improvement in worry, anxiety, depression, and quality of life following CBT relative to MCC. Forty-five percent of patients in CBT were classified as responders, relative to 8% in MCC. Most gains for patients in CBT were maintained or enhanced over 1-year follow-up. However, posttreatment scores for patients in CBT failed to indicate return to normative functioning.

Subclinical symptoms of panic disorder: new insights into pathophysiology and treatment

The aim of this review was to survey the available literature on prodromal and residual symptoms of panic disorder. Both a computerized (Medline) and a manual search of the literature were performed. In a substantial proportion of patients with panic disorder with agoraphobia a prodromal phase can be identified. Most patients report residual symptoms despite successful treatment. Residual symptoms upon remission have a prognostic value. There appears to be a relationship between residual and prodromal symptomatology (the rollback phenomenon). Appraisal of subclinical symptomatology in panic disorder has important implications as to the pathophysiological model of disease, its conceptualization and treatment.

Rate of improvement during cognitive-behavioral group treatment for panic disorder

This study examined the rate of symptom improvement in patients receiving cognitive-behavioral group treatment for panic disorder in an outpatient clinic setting. Treatment was a standard program of 12 sessions that emphasized information, interoceptive and situational exposure, and cognitive restructuring, but also included diaphragmatic breathing and relaxation training as elements of treatment. Subjects were 37 patients selected from sequential admissions into an outpatient treatment program; all data were derived from ongoing quality assurance measures that are a standard part of clinical monitoring. Consequently, this study provides data not on the relative efficacy of cognitive-behavioral therapy (CBT), but on rate of improvement and effectiveness of CBT for panic disorder in actual clinical practice. Patients achieved significant treatment gains on all panic disorder dimensions assessed, and the largest reduction in symptoms was during the first third of the treatment program, thereby challenging the notion that CBT delivers its gains slowly over time. Information on rats of symptom improvement is valuable for providing patients with accurate expectations about potential treatment benefits and for helping to maintain motivation during initial treatment sessions.
