Does Researcher Allegiance Bias Outcomes in Psychotherapy Research? A Quasi-Experimental Secondary Analysis. Clin Psychol Psychother 2024; 31:e2974. [PMID: 38616708 DOI: 10.1002/cpp.2974] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2023] [Revised: 03/08/2024] [Accepted: 03/11/2024] [Indexed: 04/16/2024]
Abstract
Researchers who conduct studies comparing the efficacy of two treatments often find that their preferred treatment outperforms the comparison treatment. This finding has been labelled the allegiance association. Although this association is robust, it is unclear whether it reflects an allegiance bias on the part of the researchers or whether it is noncausal, with researchers being allied to the more effective treatments. This study applied a quasi-experimental method proposed by a previous study to 19 pairs of treatment comparison studies. Each member of a pair had used the same two psychotherapies to treat clients with the same disorder, but the researchers in each of the two studies had opposing allegiances. If the authors of one study in the pair concluded that their preferred treatment was superior and the authors of the other study concluded that their preferred treatment was superior or that the two treatments were equivalent, these patterns would suggest allegiance bias. In 10 of the 19 pairs, the patterns were consistent with the operation of an allegiance bias, indicating that although allegiance biases are not inevitable, they are ubiquitous. Practitioners and other psychotherapy research consumers should use caution when interpreting the findings from treatment comparison studies.

Comparative efficacy and acceptability of psychotherapies for panic disorder with or without agoraphobia: systematic review and network meta-analysis of randomised controlled trials. Br J Psychiatry 2022; 221:507-519.

Abstract
BACKGROUND Psychotherapies are the treatment of choice for panic disorder, but which should be considered as first-line treatment is yet to be substantiated by evidence. AIMS To examine the most effective and accepted psychotherapy for the acute phase of panic disorder with or without agoraphobia via a network meta-analysis. METHOD We conducted a systematic review and network meta-analysis of randomised controlled trials (RCTs) to examine the most effective and accepted psychotherapy for the acute phase of panic disorder. We searched MEDLINE, Embase, PsycInfo and CENTRAL, from inception to 1 Jan 2021 for RCTs. Cochrane and PRISMA guidelines were used. Pairwise and network meta-analyses were conducted using a random-effects model. Confidence in the evidence was assessed using Confidence in Network Meta-Analysis (CINeMA). The protocol was published in a peer-reviewed journal and in PROSPERO (CRD42020206258). RESULTS We included 136 RCTs in the systematic review. Taking into consideration efficacy (7352 participants), acceptability (6862 participants) and the CINeMA confidence in evidence appraisal, the best interventions in comparison with treatment as usual (TAU) were cognitive-behavioural therapy (CBT) (for efficacy: standardised mean differences s.m.d. = -0.67, 95% CI -0.95 to -0.39; CINeMA: moderate; for acceptability: relative risk RR = 1.21, 95% CI -0.94 to 1.56; CINeMA: moderate) and short-term psychodynamic therapy (for efficacy: s.m.d. = -0.61, 95% CI -1.15 to -0.07; CINeMA: low; for acceptability: RR = 0.92, 95% CI 0.54-1.54; CINeMA: moderate). After removing RCTs at high risk of bias only CBT remained more efficacious than TAU. CONCLUSIONS CBT and short-term psychodynamic therapy are reasonable first-line choices. Studies with high risk of bias tend to inflate the overall efficacy of treatments. Results from this systematic review and network meta-analysis should inform clinicians and guidelines.

Protocol for a randomised controlled feasibility study examining the efficacy of brief cognitive therapy for the treatment of panic disorder in adolescents (PANDA). Pilot Feasibility Stud 2022; 8:49. [PMID: 35241182 PMCID: PMC8891743 DOI: 10.1186/s40814-022-01009-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2021] [Accepted: 02/18/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Panic disorder occurs in between 1 and 3% of adolescents, is associated with high levels of co-morbidity, and without treatment, appears to have a chronic course. To improve access to effective psychological interventions, briefer versions of cognitive behaviour therapy (CBT) have been developed and evaluated for preadolescent children with anxiety disorders. However, there are currently no brief evidence-based CBT interventions for adolescents with anxiety disorders that can be delivered in less than eight sessions. Given that a brief version of cognitive therapy has been shown to be effective in adults with panic disorder, it is possible that an adapted version could be effective for adolescents with panic disorder. METHODS The study will examine whether a definitive trial can be conducted, based on a single-centre feasibility randomised controlled trial using several well-defined criteria. Between 30 and 48 young people (age 11-18 years) who meet diagnostic criteria for panic disorder, attending a routine clinical service will be randomly allocated to receive either (i) brief cognitive therapy or (ii) a general form of CBT treatment that is more commonly used for adolescents with anxiety disorders. Both will be delivered 1:1 by a therapist and involve five treatment sessions and two booster sessions. Young people's outcomes will be assessed at the end of treatment and at 3-month follow-up, and qualitative interviews will be conducted to examine acceptability. We will also explore outcomes 1 year after the completion of treatment. DISCUSSION This study will test the feasibility of a randomised controlled trial to compare brief cognitive therapy to a general form of CBT for adolescents with panic disorder in the UK. The outputs from the study will provide a clear indication of the feasibility of a future definitive trial and, if indicated, the critical resources that will be required and key information to inform the design and maximise the successful completion of the trial. This has the potential to bring direct benefits to young people and their families, as well as services and society more broadly. TRIAL REGISTRATION This trial is registered on the ISRCTN Registry, registration number ISRCTN14884288 , registered retrospectively on 05/12/2019.

The effectiveness of schema therapy for patients with anxiety disorders, OCD, or PTSD: A systematic review and research agenda. BRITISH JOURNAL OF CLINICAL PSYCHOLOGY 2021; 61:579-597. [PMID: 34296767 PMCID: PMC9544733 DOI: 10.1111/bjc.12324] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2021] [Revised: 07/09/2021] [Indexed: 11/30/2022]
Abstract
Objectives We reviewed the evidence regarding the effectiveness of schema therapy for anxiety disorders, obsessive‐compulsive disorder (OCD), and posttraumatic stress disorder (PTSD). Methods This systematic review followed the recommendation of the PRISMA guidelines. A database search (PsycINFO, MEDLINE, EMBASE, WEB OF SCIENCE, and Academic Search Ultimate) was conducted to identify eligible studies up until 2 April 2021. The search included the keywords (‘schema therap*’ or ‘schema group therap*’ or ‘schema mode therap*’ or ‘schema focused’ or ‘young’s model’) and (‘anxiety disorder*’ or ‘anxiety‐related disorder*’ or ‘agoraphobia’ or ‘health anxiety’ or ‘phobi*’ or ‘panic disorder’ or ‘obsessive compulsive disorder’ or ‘OCD’ or ‘posttraumatic stress’ or ‘post traumatic stress’ or ‘PTSD’ or ‘hypochondria’ or ‘axis 1’). Included studies were appraised on methodological quality according to the Psychotherapy Outcome study Methodology Rating Form. Results We identified 41 studies that were eligible based on the topic. However, only six (comprising 316 anxiety, OCD, and PTSD patients) could be included despite lenient methodological inclusion/exclusion criteria. Results showed that schema therapy can lead to beneficial effects in disorder‐specific symptoms and early maladaptive schemas. Yet, we also uncovered substantial methodological limitations in most studies. Conclusions Schema therapy is a promising treatment for anxiety, OCD, and PTSD. Yet, there is a systematic problem in the quality of research despite growing clinical interest and application. We therefore concluded with a research agenda presenting recommendations for future research that will be crucial for building a solid evidence‐base for schema therapy in chronic anxiety, OCD, and PTSD. Practitioner points A systematic review on the effectiveness of schema therapy for anxiety disorders, OCD, and PTSD. Preliminary but limited evidence that schema therapy leads to beneficial effects in disorder‐specific symptoms. Preliminary but limited evidence that schema therapy leads to beneficial effects in early maladaptive schemas in anxiety, OCD, and PTSD. More research of higher methodological quality is needed to provide more conclusive empirical support for the use of schema therapy for anxiety, OCD, and PTSD.

Evaluation of mechanism of change in transdiagnostic cognitive behaviour therapy using single case experimental design. J Behav Ther Exp Psychiatry 2021; 71:101634. [PMID: 33388441 DOI: 10.1016/j.jbtep.2020.101634] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/25/2019] [Revised: 10/07/2020] [Accepted: 12/07/2020] [Indexed: 11/26/2022]
Abstract
BACKGROUND AND OBJECTIVES Transdiagnostic mechanisms of change (txMOC) specific to cognitive behaviour therapy are poorly understood. Salkovskis (1996) proposed one such mechanism in terms of the shift towards an alternative, less negative view of their problems or cognitive flexibility. This hypothesis has been described as involving a shift in beliefs, from "theory A″ to "theory B". The objective of this research was to evaluate this hypothesis. METHODS Effectiveness of a novel txCBT and temporal changes in process and symptom measures were evaluated using a non-concurrent multiple baseline design and Tau-U calculations with thirteen participants (five with obsessive-compulsive disorder, two with panic disorder with agoraphobia and six with major depressive disorder). As a secondary analysis authors calculated Kendall's - Tau correlation between process and symptom measures, performed the Wilcoxon signed-rank test to assess treatment modules effect on negative thought and calculated Reliable change index (RCI). RESULTS The txCBT was clearly effective for eight participants. The results varied dependent on the stimuli evaluated as negative or threatening. Level and trend of the ratings of belief in theory A followed the level and trend of symptom measures to a greater extent than the (inverse) level and trend of belief in theory B. LIMITATIONS Only thirteen participants were recruited and evaluated. CONCLUSIONS The results are consistent with the view that effective treatment may involve a txMOC characterized by the ability to shift from a relatively fixed negative view of their experience to a less negative psychologically focused alternative.

Abstract
Comorbid social anxiety and alcohol use disorders (SAD-AUD) in the community and the complex interactions that occur between these disorders have emerged as a significant clinical, public health, and research issue. The authors examined (a) the rates of comorbid SAD-AUD, (b) the impact of comorbid SAD-AUD on outcomes targeting social anxiety disorder, and (c) the effect of pretreatment alcohol consumption and alcohol use before, during, and after social situations on a composite measure of social anxiety in 172 adults presenting with social anxiety disorder. There was low incidence of AUD in this sample of individuals with SAD. Results indicated that alcohol consumption did not lead to worse social anxiety symptoms; however, alcohol use before and during social situations was associated with more severe social anxiety symptoms. These findings suggest that the function of alcohol use may be more important than the overall level of alcohol use and has implications for treatment.

Abstract
BACKGROUND Guided Internet-based cognitive behavioural therapy (ICBT) is a recommended treatment for panic disorder promising to increase treatment availability, but there are some concerns regarding adherence, including adherence to the in vivo exposure given as home assignments. The aim of this study was to assess the feasibility of combining ICBT with physical exercise with the aim of improving adherence and treatment response to ICBT. METHOD 12 participants were included via routine clinical practice to an open pre- post trial of feasibility using ICBT and an aerobe exercise protocol. We used a mixed model design investigating multiple areas of adherence, participants' experience and clinical outcome. RESULTS 90.9% of the participants was considered completers in the ICBT program and the average adherence to the physical exercise was 93.1%. The experience of participating was summarized as "Hard work but worth it". Clinical outcomes effect sizes (d) ranged from 2.79 (panic severity) to .64 (Beck's anxiety index). CONCLUSION The sum results on adherence, qualitative and quantitative data all suggest that augmenting ICBT with an aerobic exercise protocol is feasible. We conclude that further research is warranted.

Abstract
BACKGROUND Evidence-based treatment for panic disorder consists of disorder-specific cognitive behavioural therapy (CBT) protocols. However, most measures of CBT competence are generic and there is a clear need for disorder-specific assessment measures. AIMS To fill this gap, we evaluated the psychometric properties of the Cognitive Therapy Competence Scale (CTCP) for panic disorder. METHOD CBT trainees (n = 60) submitted audio recordings of CBT for panic disorder that were scored on a generic competence measure, the Cognitive Therapy Scale - Revised (CTS-R), and the CTCP by markers with experience in CBT practice and evaluation. Trainees also provided pre- to post-treatment clinical outcomes on disorder-specific patient report measures for cases corresponding to their therapy recordings. RESULTS The CTCP exhibited strong internal consistency (α = .79-.91) and inter-rater reliability (ICC = .70-.88). The measure demonstrated convergent validity with the CTS-R (r = .40-.54), although investigation into competence classification indicated that the CTCP may be more sensitive at detecting competence for panic disorder-specific CBT skills. Notably, the CTCP demonstrated the first indication of a relationship between therapist competence and clinical outcome for panic disorder (r = .29-.35); no relationship was found for the CTS-R. CONCLUSIONS These findings provide initial support for the reliability and validity of the CTCP for assessing therapist competence in CBT for panic disorder and support the use of anxiety disorder-specific competence measures. Further investigation into the psychometric properties of the measure in other therapist cohorts and its relationship with clinical outcomes is recommended.

The identification and psychological treatment of panic disorder in adolescents: a survey of CAMHS clinicians. Child Adolesc Ment Health 2020; 25:135-142.

Abstract
BACKGROUND Panic disorder is experienced by around 1% of adolescents and has a significant impact on social and academic functioning. Preliminary evidence supports the effectiveness of panic disorder-specific treatment in adolescents with panic disorder; however, panic disorder may be overlooked in adolescents due to overlapping symptoms with other anxiety disorders and other difficulties being more noticeable to others. The aim of this study was to establish what training National Health Service (NHS) Child and Adolescent Mental Health Services (CAMHS) clinicians have received in psychological therapies and panic disorder and how they identify and treat panic disorder in adolescents. METHOD CAMHS clinicians from a range of professions (n = 427), who were delivering psychological treatments to children and adolescents with anxiety disorders, participated. They completed a cross-sectional, online survey, including a vignette describing an adolescent with panic disorder, and were asked to identify the main diagnosis or presenting problem. RESULTS Less than half the clinicians (48.6%) identified panic disorder or panic symptoms as the main presenting problem from the vignette. The majority of clinicians suggested CBT would be their treatment approach. However, few identified an evidence-based treatment protocol for working with young people with panic disorder. Almost half the sample had received no training in cognitive behaviour therapy (CBT), and around a fifth had received no training in delivering psychological treatments. CONCLUSIONS Only half of CAMHS clinicians identified panic disorder from a vignette and although CBT treatments are widely offered, only a minority of adolescents with panic disorder are receiving treatments developed for and evaluated with young people with panic disorder. There is a vital need for clinician training, the use of tools that aid identification and the implementation of evidence-based treatments within CAMHS. KEY PRACTITIONER MESSAGE Panic disorder affects around 1% of adolescents, adversely impacting social, academic and long-term life functioning. There is preliminary evidence for the effectiveness of a panic disorder-specific treatment of panic disorder in adolescents. Clinicians struggle to identify panic disorder or suitable treatment protocols for treating adolescents, although most would use CBT as the treatment approach. There is a vital need for clinician training, tools that aid identification of young people with panic disorder and evidence-based treatments that can be delivered in routine clinical settings.

Abstract
OBJECTIVE The present study examined the contribution of panic appraisal (PA) dimensions to the prediction of panic and agoraphobic symptoms, above and beyond anxiety sensitivity (AS), among patients with panic disorder. PA dimensions consist of anticipated panic, perceived panic consequences, and panic coping efficacy. METHOD Panic disorder patients (N = 84, 60.7% female, M = 38 years) completed self-report measures of panic and agoraphobic symptoms, three dimensions of PA, AS, anxiety, and depression symptoms. RESULTS PA dimensions significantly contributed to the prediction of overall and all facets of panic and agoraphobic symptoms, as well as anxiety symptoms, but not depressive symptoms, above and beyond AS. Of the three PA dimensions, both anticipated panic and panic coping efficacy uniquely contributed to agoraphobic avoidance after controlling for AS and the other dimensions of PA. CONCLUSION PA dimensions may emerge as an important predictor of panic and agoraphobic or anxiety symptoms.

Abstract
SummaryPanic attacks and the antipanic effect of antidepressants are claimed to distinguish panic disorder (PD) from generalised anxiety disorder. However, most studies showing neurochemical disturbances in PD overlook the non-panic state. We compared panic patients in the non-panic state with controls on biochemical, psychological and physiological measures. There were no differences on the neuroendocrine tests. Self-ratings of bodily and psychological symptoms of anxiety were significantly higher in patients and they scored worse on word recall. Patients had significantly more skin conductance fluctuations and slow wave activity in the electroencephalogram, a sign of hyperventilation which may have implications for brain activity. Discrepancies between patients' self-ratings and objective measures of pulse rate and psychomotor performance indicated that panic patients have distorted perceptions of both physical and mental functioning. Hyperventilation and cognitive distortions in the non-panic state may facilitate panic attacks and are part of the pathophysiology of PD.

Neurocognitive processes in d-cycloserine augmented single-session exposure therapy for anxiety: A randomized placebo-controlled trial. Behav Res Ther 2020; 129:103607.

Abstract
Drugs targeting N-methyl-d-aspartate (NMDA) receptors and the ability to learn new associations have been proposed as adjunct treatments to boost the success of exposure therapy for anxiety disorders. However, the effects of the NMDA partial agonist d-cycloserine on psychological treatment have been mixed. We investigated potential neurocognitive mechanisms underlying the clinical effects of d-cycloserine-augmented exposure, to inform the optimal combination of this and similar agents with psychological treatment. Panic disorder patients were randomised to single-dose d-cycloserine (250 mg; N = 17) or matching placebo (N = 16) 2hrs before one session of exposure therapy. Neurocognitive markers were assessed one day after treatment, including reaction-time based threat bias for fearful faces (primary outcome) and amygdala response to threat (secondary outcome). Clinical symptom severity was measured the day before and after treatment, and at 1- and 6-months follow-up (secondary outcome). d-cycloserine was associated with greater clinical recovery at 1-month follow-up than placebo (d-cyloserine 71% vs placebo 25%), with the placebo group matching the clinical gains of the d-cycloserine group during 6-months follow-up (d-cycloserine 71% vs placebo 44%). One day after treatment, threat bias for fearful faces and amygdala threat response was lower in the drug compared to placebo group. Lower amygdala magnitude predicted greater clinical improvement during follow-up across groups. While this experimental study is of a preliminary nature due to the limited sample size, these findings highlight a neurocognitive potential mechanism by which d-cycloserine may exert its augmentative effects on psychological treatment and bring forward a marker that may help understand and facilitate development of combination treatments for anxiety.

Abstract
BACKGROUND The innovative treatment model Improving Access to Psychological Therapies (IAPT) and its Norwegian adaptation, Prompt Mental Health Care (PMHC), have been evaluated by cohort studies only. Albeit yielding promising results, the extent to which these are attributable to the treatment thus remains unsettled. OBJECTIVE To investigate the effectiveness of the PMHC treatment compared to treatment as usual (TAU) at 6-month follow-up. METHODS A randomized controlled trial with parallel assignment was performed in two PMHC sites (Sandnes and Kristiansand) and enrolled clients between November 9, 2015 and August 31, 2017. Participants were 681 adults (aged ≥18 years) considered for admission to PMHC due to anxiety and/or mild to moderate depression (Patient Health Questionnaire [PHQ-9]/Generalized Anxiety Disorder scale [GAD-7] scores above cutoff). These were randomly assigned (70:30 ratio; n = 463 to PMHC, n = 218 to TAU) with simple randomization within each site with no further constraints. The main outcomes were recovery rates and changes in symptoms of depression (PHQ-9) and anxiety (GAD-7) between baseline and follow-up. Primary outcome data were available for 73/67% in PMHC/TAU. Sensitivity analyses based on observed patterns of missingness were also conducted. Secondary outcomes were work participation, functional status, health-related quality of life, and mental well-being. RESULTS A reliable recovery rate of 58.5% was observed in the PMHC group and of 31.9% in the TAU group, equaling a between-group effect size of 0.61 (95% CI 0.37 to 0.85, p < 0.001). The differences in degree of improvement between PMHC and TAU yielded an effect size of -0.88 (95% CI -1.23 to -0.43, p < 0.001) for PHQ-9 and -0.60 (95% CI -0.90 to -0.30, p < 0.001) for GAD-7 in favor of PMHC. All sensitivity analyses pointed in the same direction, with small variations in point estimates. Findings were slightly more robust for depressive than anxiety symptoms. PMHC was also more effective than TAU in improving all secondary outcomes, except for work participation (z = 0.415, p = 0.69). CONCLUSIONS The PMHC treatment was substantially more effective than TAU in alleviating the burden of anxiety and depression. This adaptation of IAPT is considered a viable supplement to existing health services to increase access to effective treatment for adults who suffer from anxiety and mild to moderate depression. A potential effect on work participation needs further examination.

Abstract
To examine process of changes in two distinct psychotherapies-cognitive-behavioral therapy (CBT) and Panic-Focused Psychodynamic Psychotherapy (PFPP). Two hypothesized processes of change-misinterpretation of bodily sensations and Panic Specific Reflective Function (PSRF)-were tested in the CBT and PFPP arms of the Cornell-Penn Study of Psychotherapies for Panic Disorder. The Brief Bodily Sensations Interpretation Questionnaire (BBSIQ) measures misinterpretation of bodily sensations-a focus of CBT interventions. PSRF, a target of PFPP, assesses the capacity to reflect on the underlying meaning of panic symptoms. A sample of 138 patients (37.7% men, 72.56% Whites, and 16.7% Latinx) with primary Diagnostic and Statistical Manual for Mental Disorders-Fourth Edition (DSM-IV) panic disorder were included in the present analyses. Mixed effects models tested the effects of early change in BBSIQ and PSRF (intake through Week 5) on subsequent change in the Panic Disorder Severity Scale (PDSS; Week 5 through termination). Early change on both PSRF and BBSIQ predicted subsequent change in panic severity across the two treatments. As predicted, PSRF changed more in PFPP than in CBT, but, contrary to expectation, BBSIQ showed comparable changes in both groups. Counterintuitively, CBT patients benefited more in terms of panic symptom improvement when their PSRF improved than did PFPP patients. This is the first demonstration of general processes of change (PSRF and BBSIQ) across psychotherapies for panic disorder, suggesting that to the extent patients change their beliefs about the meaning of panic, their panic symptoms improve in time-limited, panic-focused psychotherapies.

Abstract
Complementary and alternative medicine (CAM) encompasses a wide range of different nonmainstream therapies that have been increasingly used for treatment or adjunctive treatment of various ailments with anxiety/anxiety disorders being one of the commonly CAM (self)-medicated conditions. Thousands of published papers refer to use of CAM in various psychiatric disorders or in healthy or medically ill patients with mood or anxiety difficulties. In this chapter we focus specifically on clinically diagnosed (in line with the standard criteria) anxiety disorders and overview evidence of efficacy/safety of a range of CAM modalities: biologically based therapies (typically herbal preparations and less so nutraceuticals); manipulative and body-based therapies (acupuncture, aerobic exercise, massage, therapeutic touch, repetitive transcranial magnetic stimulation, balneotherapy, and others); mind-body therapies (yoga, Morita therapy, Tai Chi, reiki, Chinese cognitive therapy, religious and spiritual interventions, relaxation, mediation, and mindfulness-based interventions); and alternative medical systems (Ayurveda, homeopathy). We focus exclusively on randomized controlled trials and attempt to evaluate the existing body of evidence in the same manner that is applied to mainstream treatments.

Differential effects of alliance and techniques on Panic-Specific Reflective Function and misinterpretation of bodily sensations in two treatments for panic. Psychother Res 2020; 30:97-111. [PMID: 30821630 PMCID: PMC6778028 DOI: 10.1080/10503307.2019.1585591] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/07/2018] [Revised: 01/21/2019] [Accepted: 01/21/2019] [Indexed: 10/27/2022] Open
Abstract
ABSTRACTObjective: To examine whether working alliance quality and use of techniques predict improvement in Panic-Specific Reflection Function (PSRF), and misinterpretation of bodily sensations in treatments for panic disorder. Method: A sample of 161 patients received either CBT or PFPP (Panic-focused Psychodynamic therapy) within a larger RCT. Data were collected on patient-reported working alliance, misinterpretations, PSRF, observer-coded use of techniques, and interviewer-rated panic severity. Random-Intercept Cross-Lagged Panel Models assessed bi-directional associations, disentangling within- and between-patient effects, and accounting for prior change. Results: Higher alliance predicted subsequent within-patient improvement in PSRF in PFPP, but worsening in CBT. In both treatments, focus on interpersonal relationships predicted PRSF improvement (with stronger effects in CBT), while focus on thoughts and behaviors predicted worsening in PSRF. In CBT only, early focus on affect and moment-to-moment experience predicted reduced misinterpretation, while high focus on thoughts and cognitions predicted subsequent increase in misinterpretation. Conclusion: The quality of the alliance has differential effects on PSRF in distinct treatments. Interpersonal, rather than cognitive or behavioral focus, even when delivered differently within distinct treatments with high adherence, could facilitate improvement in PSRF. Additionally, early focus on affect and moment-to-moment experiences in CBT could reduce misinterpretations.

Effects of cognitive behavioural therapy and return-to-work intervention for patients on sick leave due to stress-related disorders: Results from a randomized trial. Scand J Psychol 2019; 61:281-289. [PMID: 31691305 DOI: 10.1111/sjop.12590] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2019] [Accepted: 09/16/2019] [Indexed: 11/28/2022]
Abstract
The aim of this study was to evaluate specific effects for patients with adjustment or exhaustion disorder, the Stress subgroup (n = 152), regarding symptom severity and sick leave after CBT, a return-to-work intervention (RTW-I), and a combination of them (COMBO), using data from a randomized trial. In the original study, primary care patients on sick leave (N = 211) were randomized to CBT (n = 64), RTW-I (n = 67), or COMBO (n = 80). Blinded Clinician Severity Rating (CSR) of symptoms and sick leave registry data were primary outcomes. Subgroup analyses showed that for the Stress subgroup, CBT led to greater reduction of symptoms than RTW-I posttreatment, but COMBO did not differ from CBT or RTW-I. Regarding sick leave, there was no difference between treatments in the Stress subgroup. An exploratory analysis of the treatment effects in a subgroup of patients with depression, anxiety or insomnia indicates that RTW-I reduced sick leave faster than CBT. We conclude that CBT may be promising as an effective treatment of stress and exhaustion disorder.

Efficacy of intergrating vestibular rehabilitation and cognitive behaviour therapy in persons with persistent dizziness in primary care- a study protocol for a randomised controlled trial. Trials 2019; 20:575. [PMID: 31590692 PMCID: PMC6781377 DOI: 10.1186/s13063-019-3660-5] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2019] [Accepted: 08/14/2019] [Indexed: 01/13/2023] Open
Abstract
Background Dizziness is a common complaint, and the symptom often persists, together with additional complaints. A treatment combining Vestibular Rehabilitation (VR) and Cognitive Behaviour Therapy (CBT) is suggested. However, further research is necessary to evaluate the efficacy of such an intervention. The objective of this paper is to present the design of a randomised controlled trial aiming at evaluating the efficacy of an integrated treatment of VR and CBT on dizziness, physical function, psychological complaints and quality of life in persons with persistent dizziness. Methods/design The randomised controlled trial is an assessor-blinded, block-randomised, parallel-group design, with a 6- and 12-month follow-up. The study includes 125 participants from Bergen (Norway) and surrounding areas. Included participants present with persistent dizziness lasting for at least 3 months, triggered or exacerbated by movement. All participants receive a one-session treatment (Brief Intervention Vestibular Rehabilitation; BI-VR) with VR before being randomised into a control group or an intervention group. The intervention group will further be offered an eight-session treatment integrating VR and CBT. The primary outcomes in the study are the Dizziness Handicap Inventory and preferred gait velocity. Discussion Previous studies combining these treatments have been of varying methodological quality, with small samples, and long-term effects have not been maintained. In addition, only the CBT has been administered in supervised sessions, with VR offered as home exercises. The current study focusses on the integrated treatment, a sufficiently powered sample size, and a standardised treatment programme evaluated by validated outcomes using a standardised assessment protocol.

Abstract
Purpose To evaluate the feasibility of integrating vestibular rehabilitation and cognitive behaviour therapy (VR-CBT) for people with persistent dizziness in primary care. Design Prospective single-group pre- and post-test study. Participants Adults (aged 18–70) with acute onset of dizziness and symptoms lasting a minimum 3 months, recruited from Bergen municipality. Methods Participants attended eight weekly group sessions of VR-CBT intervention. Feasibility outcomes consisted of recruitment and testing procedures, intervention adherence, and participant feedback, besides change in primary outcomes. The primary outcomes were Dizziness Handicap Inventory (DHI) and preferred gait velocity. Results Seven participants were recruited for the study. All participants completed the pre-treatment tests, five participants completed the intervention and answered post-treatment questionnaires, and three completed post-treatment testing. Of the five participants, three attended at least 75% of the VR-CBT sessions, and two 50% of the sessions. Participants reported that the VR-CBT was relevant and led to improvement in function. DHI scores improved beyond minimal important change in two out of five participants, and preferred gait velocity increased beyond minimal important change in two out of three participants. Conclusion The current tests and VR-CBT treatment protocols were feasible. Some changes are suggested to optimise the protocols, before conducting a randomised controlled trial.

Protocol for a randomised controlled feasibility study examining the efficacy of brief cognitive therapy for the Treatment of Anxiety Disorders in Adolescents (TAD-A). Trials 2019; 20:240.

Abstract
Background Anxiety disorders affect a quarter of the population during their lifetime, and typically emerge in childhood or adolescence. Anxiety disorders disrupt young people’s social, emotional and academic development and in the absence of treatment, often follow a chronic course. Although effective treatments, such as Cognitive Behaviour Therapy (CBT), exist, only a small proportion of adolescents with anxiety disorders who need treatment receive them. Barriers to treatment provision include the fact that CBT typically requires 14–16 sessions by a highly qualified therapist and services are stretched – resulting in lengthy waiting lists and limited access to treatment. This highlights the importance of developing new ways of providing effective treatments for adolescent anxiety disorders. This study aims to assess the feasibility of a future, large-scale trial. This will give a clear indication of the likely success of running a randomised controlled trial to compare a new, brief cognitive therapy treatment to an existing CBT group therapy for adolescents with anxiety disorders. Methods/design The study will examine whether a definitive trial can be conducted on the basis of a feasibility RCT using a number of well-defined criteria. The feasibility RCT is a single-centre, randomised control trial. Forty-eight Young people (age 11–17.5 years) attending a university research clinic, who meet the diagnostic criteria for a DSM-5 anxiety disorder, will be randomly allocated to receive either (1) Adolescent Cognitive Therapy for Anxiety (ACTA), which involves six 60–90-min sessions and a booster session or (2) group CBT, which involves eight 2-h sessions and a booster session. As part of the feasibility indicators, patient outcomes, expectations and experiences, as well as health economic factors, will be assessed before, at the end of treatment and at a 3-month follow-up. Discussion The successful delivery of a future, definitive trial has the potential to bring direct benefits to young people and their families, adolescent mental health service providers, as well as benefits to adult mental health services and society more broadly by disrupting the negative trajectory commonly associated with adolescent anxiety disorders.

Internet-Based Cognitive Behavioral Therapy With Real-Time Therapist Support via Videoconference for Patients With Obsessive-Compulsive Disorder, Panic Disorder, and Social Anxiety Disorder: Pilot Single-Arm Trial. J Med Internet Res 2018; 20:e12091. [PMID: 30559094 PMCID: PMC6315259 DOI: 10.2196/12091] [Citation(s) in RCA: 36] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2018] [Revised: 10/29/2018] [Accepted: 11/11/2018] [Indexed: 12/18/2022] Open
Abstract
Background Cognitive behavioral therapy (CBT) is the first-line treatment for adults with obsessive-compulsive disorder (OCD), panic disorder (PD), and social anxiety disorder (SAD). Patients in rural areas can access CBT via the internet. The effectiveness of internet-delivered cognitive behavioral therapy (ICBT) has been consistently shown, but no clinical studies have demonstrated the feasibility of ICBT with real-time therapist support via videoconference for OCD, PD, and SAD at the same time. Objectives This study aimed to evaluate the feasibility of videoconference-delivered CBT for patients with OCD, PD, or SAD. Methods A total of 30 Japanese participants (mean age 35.4 years, SD 9.2) with OCD, SAD, or PD received 16 sessions of individualized videoconference-delivered CBT with real-time support of a therapist, using tablet personal computer (Apple iPad Mini 2). Treatment involved individualized CBT formulations specific to the presenting diagnosis; all sessions were provided by the same therapist. The primary outcomes were reduction in symptomatology, using the Yale-Brown obsessive-compulsive scale (Y-BOCS) for OCD, Panic Disorder Severity Scale (PDSS) for PD, and Liebowitz Social Anxiety Scale (LSAS) for SAD. The secondary outcomes included the EuroQol-5 Dimension (EQ-5D) for Quality of Life, the Patient Health Questionnaire (PHQ-9) for depression, the Generalized Anxiety Disorder (GAD-7) questionnaire for anxiety, and Working Alliance Inventory-Short Form (WAI-SF). All primary outcomes were assessed at baseline and at weeks 1 (baseline), 8 (midintervention), and 16 (postintervention) face-to-face during therapy. The occurrence of adverse events was observed after each session. For the primary analysis comparing between pre- and posttreatments, the participants’ points and 95% CIs were estimated by the paired t tests with the change between pre- and posttreatment. Results A significant reduction in symptom of obsession-compulsion (Y-BOCS=−6.2; Cohen d=0.74; 95% CI −9.4 to −3.0, P=.002), panic (PDSS=−5.6; Cohen d=0.89; 95% CI −9.83 to −1.37; P=.02), social anxiety (LSAS=−33.6; Cohen d=1.10; 95% CI −59.62 to −7.49, P=.02) were observed. In addition, depression (PHQ-9=−1.72; Cohen d=0.27; 95% CI −3.26 to −0.19; P=.03) and general anxiety (GAD-7=−3.03; Cohen d=0.61; 95% CI −4.57 to −1.49, P<.001) were significantly improved. Although there were no significant changes at 16 weeks from baseline in EQ-5D (0.0336; Cohen d=-0.202; 95% CI −0.0198 to 0.00869; P=.21), there were high therapeutic alliance (ie, WAI-SF) scores (from 68.0 to 73.7) throughout treatment, which significantly increased (4.14; 95% CI 1.24 to 7.04; P=.007). Of the participants, 86% (25/29) were satisfied with videoconference-delivered CBT, and 83% (24/29) preferred videoconference-delivered CBT to face-to-face CBT. An adverse event occurred to a patient with SAD; the incidence was 3% (1/30). Conclusions Videoconference-delivered CBT for patients with OCD, SAD, and SAD may be feasible and acceptable.

Prompt mental health care, the Norwegian version of IAPT: clinical outcomes and predictors of change in a multicenter cohort study. BMC Psychiatry 2018; 18:260. [PMID: 30115041 PMCID: PMC6097447 DOI: 10.1186/s12888-018-1838-0] [Citation(s) in RCA: 34] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/06/2018] [Accepted: 08/07/2018] [Indexed: 11/05/2022] Open
Abstract
BACKGROUND Prompt mental health care (PMHC) is a Norwegian initiative, inspired by the English 'Improving Access to Psychological Therapy' (IAPT), aimed to provide low-threshold access to primary care treatment for persons with symptoms of anxiety and depression. The objectives of the present study are to describe the PMHC service, to examine changes in symptoms of anxiety and depression following treatment and to identify predictors of change, using data from the 12 first pilot sites. METHODS A prospective cohort design was used. All participants were asked to complete questionnaires at baseline, before each treatment session and at the end of treatment. Effect sizes (ES) for pre-post changes and recovery rates were calculated based on the Patient Health Questionnaire and the Generalized Anxiety Disorder scale. Multiple imputation (MI) was used in order to handle missing data. We examined predictors through latent difference score models and reported the contribution of each predictor level in terms of ES. RESULTS In total, N = 2512 clients received treatment at PMHC between October 2014 and December 2016, whereof 61% consented to participate. The changes from pre- to post-treatment were large for symptoms of both depression (ES = 1.1) and anxiety (ES = 1.0), with an MI-based reliable recovery rate of 58%. The reliable recovery rate comparable to IAPT based on last-observation-carried-forward was 48%. The strongest predictors for less improvement were having immigrant background (ES change depression - 0.27, ES change anxiety - 0.26), being out of work at baseline (ES change depression - 0.18, ES change anxiety - 0.35), taking antidepressants (ES change anxiety - 0.36) and reporting bullying as cause of problems (ES change depression - 0.29). Taking sleep medication did on the other hand predict more improvement (ES change depression 0.23, ES change anxiety 0.45). CONCLUSIONS Results in terms of clinical outcomes were promising, compared to both the IAPT pilots and other benchmark samples. Though all groups of clients showed substantial improvements, having immigrant background, being out of work, taking antidepressant medication and reporting bullying as cause stood out as predictors of poorer treatment response. Altogether, PMHC was successfully implemented in Norway. Areas for improvement of the service are discussed.

Abstract
OBJECTIVE Three recent meta-analyses have made the claim, albeit with some caveats, that cognitive-behavioral treatments (CBT) are superior to other psychotherapies, in general or for specific disorders (e.g., social phobia). METHOD The purpose of the present article was to examine four issues in meta-analysis that mitigate claims of CBT superiority: (a) effect size, power, and statistical significance, (b) focusing on disorder-specific symptom measures and ignoring other important indicators of psychological functioning, (c) problems inherent in classifying treatments provided in primary studies into classes of treatments, and (d) the inclusion of problematic trials, which biases the results, and the exclusion of trials that fail to find differences among treatments. RESULTS When these issues are examined, the effects demonstrating the superiority of CBT are small, nonsignificant for the most part, limited to targeted symptoms, or are due to flawed primary studies. CONCLUSION Meta-analytic evidence for the superiority of CBT in the three meta-analysis are nonexistent or weak.

Abstract
Background:In recent years, cognitive behavioural group therapies (CBGT) have been increasingly deployed as a strategy to increase the efficiency and cost-effectiveness in treatment of common mental health problems. The vast majority of these therapies are disorder specific, but in the last few years there has been growing interest in transdiagnostic CBGT.Aims:The aim of this study was twofold: to evaluate the treatment effects of transdiagnostic CBGT on disorder specific symptoms and what (if any) differences would be observed in the treatment effects with regard to general as opposed to disorder specific symptoms measured pre- and post-treatment.Method:The participants were 233 adult patients diagnosed with depression and/or anxiety disorders. They underwent a 6-week transdiagnostic CBGT. To compare treatment effects on general and disorder specific symptoms, raw scores on all measures were converted to standardized scores.Results:Pre–post differences were significant and there was no evidence that treatment was differentially effective for general and disorder specific symptoms. Effect sizes ranged from medium to large.Conclusion:The 6-week transdiagnostic CBGT is feasible for a wide range of mood and anxiety disorders. The results indicate that low-intensity transdiagnostic group therapies may have similar effects on both general and disorder specific symptoms.

Abstract
We tested a theory-derived network of within-person causal relations between experiential states in schema therapy of Cluster C personality problems. The sample consisted of 35 patients with panic disorder and/or agoraphobia and DSM-IV Cluster C personality traits or disorders who participated in an inpatient programme. In a 6-week schema therapy phase, the patients had nine or 10 individual sessions and completed measures of experiential states (anger, sadness, depression, anxiety, optimism, and schema belief) before and after each session. The impact of these six states on each other and on themselves over time was examined in mixed models. Schema belief was positively related to subsequent anger and sadness, whereas optimism was negatively related to subsequent schema belief, sadness, and depression. The results suggest that one could maximize the effect of schema therapy on dysphoric feelings in patients with Cluster C personality problems through a therapeutic focus on optimism and schema belief.

Abstract
BACKGROUND Common mental disorders (CMD) cause large suffering and high societal costs. Cognitive behavioural therapy (CBT) can effectively treat CMD, but access to treatment is insufficient. Guided self-help (GSH) CBT, has shown effects comparable with face-to-face CBT. However, not all patients respond to GSH, and stepping up non-responders to face-to-face CBT, could yield larger response rates. The aim was to test a stepped care model for CMD in primary care by first evaluating the effects of GSH-CBT and secondly, for non-responders, evaluating the additional effect of face-to-face CBT. METHODS Consecutive patients (N = 396) with a principal disorder of depression, anxiety, insomnia, adjustment or exhaustion disorder were included. In Step I, all patients received GSH-CBT. In Step II, non-responders were randomized to face-to-face CBT or continued GSH. The primary outcome was remission status, defined as a score below a pre-established cutoff on a validated disorder-specific scale. RESULTS After GSH-CBT in Step I, 40% of patients were in remission. After Step II, 39% of patients following face-to-face CBT were in remission compared with 19% of patients after continued GSH (p = 0.004). Using this stepped care model required less than six therapy sessions per patient and led to an overall remission rate of 63%. CONCLUSIONS Stepped care can be effective and resource-efficient to treat CMD in primary care, leading to high remission rates with limited therapist resources. Face-to-face CBT speeded up recovery compared with continued GSH. At follow-ups after 6 and 12 months, remission rates were similar in the two groups.

Abstract
AbstractImagery rescripting (ImRs) is a psychological intervention designed to change the meaning of images and associated memories and reduce emotional distress. Recent studies have shown that ImRs can be successfully applied to many psychological problems and disorders; however, little has been reported on the application of ImRs for panic disorder (PD). Consequently, we explored the therapeutic effects of ImRs on patients with PD. Fifteen patients with PD received 16 individual cognitive behavioural therapy (CBT) sessions weekly, including one ImRs session. Early traumatic memories associated with recurrent images in panic situations were identified and rescripted to alleviate maladaptive encapsulated beliefs. ImRs ratings (vividness and distress of the images and memories and conviction degree of encapsulated beliefs) were measured prior to and after ImRs. Self-negative contents not directly related to symptoms of panic attack were observed as common themes in the worst meaning of the image, the memory, and in the encapsulated belief. Whilst five (33%) patients had anticipatory anxiety, 10 (67%) patients had other self-negative beliefs. ImRs significantly reduced distress from images, memories and encapsulated beliefs; however, it did not change the vividness of images and memories. There was no significant correlation between the reduction in PD severity over the CBT program and the change in each ImRs rating. The results of this study are promising for certain aspects of panic disorder. However, further research is needed to overcome the limitations of this study.

Abstract
A three-session therapist-guided exposure treatment was tested in a consecutive series of eight primary health care patients suffering from panic attacks who specifically used distraction techniques as their primary safety behavior. The Panic Disorder Severity Scale Self-Report (PDSS-SR) was administered at baseline (1-3 weeks before the first session), and 1, 2, and 3 weeks after treatment. Weekly ratings on the Body Sensations Questionnaire (BSQ) and the Agoraphobic Cognitions Questionnaire (ACQ) during treatment were undertaken to explore when reliable change took place on these measures. The results showed a large within-group effect size on PDSS-SR ( d = 1.63); six of the eight patients were classified as responders, and four of them showed remission. Large effect sizes ( ds between 1.17 and 3.00) were seen also on BSQ and ACQ, as well as on agoraphobic avoidance, general level of anxiety, and depression. The results on BSQ and ACQ suggest that the fear of body sensations in most cases was reduced before a change occurred in agoraphobic cognitions. These results indicate that a brief three-session exposure-based treatment may be sufficient for this subgroup of panic patients. The findings need to be replicated under controlled conditions with larger samples and different therapists before more firm conclusions can be drawn. Future research should also focus on the relevance of dividing patients into subgroups based on type of safety behavior.

Abstract
BACKGROUND AND OBJECTIVE The purpose of the present study was to explore the association between reductions in symptoms of psychopathology and perceived centrality of negative autobiographical memories in participants with social anxiety disorder (SAD) or panic disorder (PD). METHODS Thirty-nine individuals with SAD or PD recalled and rated four negative autobiographical memories before and after ten sessions of cognitive behavioral therapy (CBT) over a three-month period. Twenty-eight healthy controls did the same before and after a three-month period. RESULTS As hypothesized, results showed a decrease in perceived centrality following CBT. This decrease in perceived centrality was larger, although at the trend level, for individuals who experienced reliable change on disorder-specific symptoms. LIMITATIONS The correlational nature of the study prevents establishing the causal relationship between changes in perceived centrality and psychopathology, and future studies should explore such mechanisms. CONCLUSIONS The present study adds to the emerging body of literature, investigating changes in centrality of event following psychotherapy.

Effects of Relaxation Therapy on Anxiety Disorders: A Systematic Review and Meta-analysis. Arch Psychiatr Nurs 2018; 32:278-284. [PMID: 29579524 DOI: 10.1016/j.apnu.2017.11.015] [Citation(s) in RCA: 32] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/02/2017] [Accepted: 11/18/2017] [Indexed: 01/04/2023]
Abstract
AIM To explore the effect of relaxation therapy applied to people with anxiety disorders. METHODS Systematic review with meta-analysis. RESULTS Sixteen Randomized Control Trials (RCTs) were included for meta-analysis to determine the effect of relaxation therapy. The overall effect of relaxation therapy on symptom of anxiety was significant with Hedges' g=0.62 (95% CI: 0.42-0.81), which indicates a medium-high effect; heterogeneity was statistically significant with I2=48.84. Subgroup analysis exploring the possible causes of heterogeneity found that types of comparison of TAU and CBT was significant (Q=4.20, p=0.04). The effect of relaxation therapy on symptoms of depression, phobia, and worry was significant; Hedges' g=0.44 (95% CI: 0.30-0.59), 0.40 (95% CI: 0.06-0.75), 0.54 (95% CI: 0.28-0.79), respectively. CONCLUSION The results of this study provide evidence for the effectiveness of relaxation therapy for people with anxiety disorders. Therefore, relaxation therapy can be selected as a useful intervention for reducing negative emotions in people with anxiety disorders.

Does cognitive behavioral therapy alter mental defeat and cognitive flexibility in patients with panic disorder? BMC Res Notes 2018; 11:23. [PMID: 29329597 PMCID: PMC5767061 DOI: 10.1186/s13104-018-3130-2] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2017] [Accepted: 01/06/2018] [Indexed: 01/01/2023] Open
Abstract
Objective Mental defeat and cognitive flexibility have been studied as explanatory factors for depression and posttraumatic stress disorder. This study examined mental defeat and cognitive flexibility scores in patients with panic disorder (PD) before and after cognitive behavioral therapy (CBT), and compared them to those of a gender- and age-matched healthy control group. Results Patients with PD (n = 15) received 16 weekly individual CBT sessions, and the control group (n = 35) received no treatment. Patients completed the Mental Defeat Scale and the Cognitive Flexibility Scale before the intervention, following eight CBT sessions, and following 16 CBT sessions, while the control group did so only prior to receiving CBT (baseline). The patients’ pre-CBT Mental Defeat and Cognitive Flexibility Scale scores were significantly higher on the Mental Defeat Scale and lower on the Cognitive Flexibility Scale than those of the control group participants were. In addition, the average Mental Defeat Scale scores of the patients decreased significantly, from 22.2 to 12.4, while their average Cognitive Flexibility Scale scores increased significantly, from 42.8 to 49.5. These results suggest that CBT can reduce mental defeat and increase cognitive flexibility in patients with PD Trial registration The study was registered retrospectively in the national UMIN Clinical Trials Registry on June 10, 2016 (registration ID: UMIN000022693).

Abstract
In many ways cognitive and behavioural therapies represent the acceptable face of psychotherapy for the general psychiatrist. They are brief, focused, problem-oriented treatments, which take symptoms seriously. They show an affinity for the medical model in their acceptance of diagnostic categories and their commitment to effective evaluation of treatments through randomised controlled trials. The wide applicability of these therapies is also attractive to the general psychiatrist. Cognitive and behavioural techniques are of major importance in the treatment of anxiety disorders, depression, eating disorders, and sexual dysfunctions, and beyond this core group the methods can be applied to enhance coping and change unwanted behaviours in conditions as diverse as cancer, chronic pain, substance abuse, anger control, schizophrenia, and challenging behaviours in people with learning disabilities.

Abstract
The human search for tranquillity has embraced the use of numerous substances of which alcohol is probably the most widely used. Alcohol acts in part by facilitating neurotransmission at γ-aminobutyric acid (GABA) synapses and until recently the pharmacological treatment of anxiety was based principally on drugs that produce similar actions on this neurotransmitter and its receptor complex (Cowen & Nutt, 1982) (Box 1).

Abstract
The term ‘challenging behaviour’ was introduced in North America in the 1980s, and was originally used to describe problematic behaviours in people with ‘mental retardation’ (learning disabilities). Challenging behaviour can, however, occur across the intellectual spectrum, being particularly prevalent in populations with psychiatric disorder.

Does schema therapy change schemas and symptoms? A systematic review across mental health disorders. Psychol Psychother 2017; 90:456-479. [PMID: 28035734 PMCID: PMC5573974 DOI: 10.1111/papt.12112] [Citation(s) in RCA: 56] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/18/2016] [Revised: 10/24/2016] [Indexed: 12/11/2022]
Abstract
PURPOSE Schema therapy was first applied to individuals with borderline personality disorder (BPD) over 20 years ago, and more recent work has suggested efficacy across a range of disorders. The present review aimed to systematically synthesize evidence for the efficacy and effectiveness of schema therapy in reducing early maladaptive schema (EMS) and improving symptoms as applied to a range of mental health disorders in adults including BPD, other personality disorders, eating disorders, anxiety disorders, and post-traumatic stress disorder. METHODS Studies were identified through electronic searches (EMBASE, PsycINFO, MEDLINE from 1990 to January 2016). RESULTS The search produced 835 titles, of which 12 studies were found to meet inclusion criteria. A significant number of studies of schema therapy treatment were excluded as they failed to include a measure of schema change. The Clinical Trial Assessment Measure was used to rate the methodological quality of studies. Schema change and disorder-specific symptom change was found in 11 of the 12 studies. CONCLUSIONS Schema therapy has demonstrated initial significant results in terms of reducing EMS and improving symptoms for personality disorders, but formal mediation analytical studies are lacking and rigorous evidence for other mental health disorders is currently sparse. PRACTITIONER POINTS First review to investigate whether schema therapy leads to reduced maladaptive schemas and symptoms across mental health disorders. Limited evidence for schema change with schema therapy in borderline personality disorder (BPD), with only three studies conducting correlational analyses. Evidence for schema and symptom change in other mental health disorders is sparse, and so use of schema therapy for disorders other than BPD should be based on service user/patient preference and clinical expertise and/or that the theoretical underpinnings of schema therapy justify the use of it therapeutically. Further work is needed to develop the evidence base for schema therapy for other disorders.

Abstract
Replicability of findings is an essential prerequisite of research. For both basic and clinical research, however, low replicability of findings has recently been reported. Replicability may be affected by research biases not sufficiently controlled for by the existing research standards. Several biases such as researcher allegiance or selective reporting are well-known for affecting results. For psychotherapy and pharmacotherapy research, specific additional biases may affect outcome (e.g. therapist allegiance, therapist effects or impairments in treatment implementation). For meta-analyses further specific biases are relevant. In psychotherapy and pharmacotherapy research these biases have not yet been systematically discussed in the context of replicability. Using a list of 13 biases as a starting point, we discuss each bias's impact on replicability. We illustrate each bias by selective findings of recent research, showing that (1) several biases are not yet sufficiently controlled for by the presently applied research standards, (2) these biases have a pernicious effect on replicability of findings. For the sake of research credibility, it is critical to avoid these biases in future research. To control for biases and to improve replicability, we propose to systematically implement several measures in psychotherapy and pharmacotherapy research, such as adversarial collaboration (inviting academic rivals to collaborate), reviewing study design prior to knowing the results, triple-blind data analysis (including subjects, investigators and data managers/statisticians), data analysis by other research teams (crowdsourcing), and, last not least, updating reporting standards such as CONSORT or the Template for Intervention Description and Replication (TIDieR).

Abstract
OBJECTIVES Anxiety disorders, most notably panic disorders and agoraphobia, are common mental disorders, and there is a high comorbidity with personality disorders. Randomized controlled trails addressing this highly relevant group of patients are missing. DESIGN The multicenter Anxiety and Personality Disorders (APD) study investigates 200 patients with panic disorder and/or agoraphobia with comorbid personality disorder in a randomized control-group comparison of psychoanalytic therapy (PT) and cognitive behavioral therapy (CBT), including 100 patients in each group. Each patient will be examined over a period of six years, regardless of the duration of the individual treatment. The main issues that are addressed in this study are the comparison of the efficacy of PT and CBT in this special patient population, the comparison of the sustainability of the effects of PT and CBT, the comparison of the long-term cost-benefit-ratios of PT and CBT as well as the investigation of prescriptive patient characteristics for individualized treatment recommendations (differential indication). DISCUSSION The APD study compares efficacy, sustainability, and cost-benefit-ratios of CBT and PT for anxiety plus personality disorders in a randomized controlled trail. The study design meets the requirements for an efficacy study for PT, which were recently defined. TRIAL REGISTRATION Current Controlled Trials ISRCTN12449681.

Abstract
BACKGROUND Panic disorder is common and deleterious to mental well-being. Psychological therapies and pharmacological interventions are both used as treatments for panic disorder with and without agoraphobia. However, there are no up-to-date reviews on the comparative efficacy and acceptability of the two treatment modalities, and such a review is necessary for improved treatment planning for this disorder. OBJECTIVES To assess the efficacy and acceptability of psychological therapies versus pharmacological interventions for panic disorder, with or without agoraphobia, in adults. SEARCH METHODS We searched the Cochrane Common Mental Disorders Group Specialised Register on 11 September 2015. This register contains reports of relevant randomised controlled trials from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (1950 to present), Embase (1974 to present), and PsycINFO (1967 to present). We cross-checked reference lists of relevant papers and systematic reviews. We did not apply any restrictions on date, language, or publication status. SELECTION CRITERIA We included all randomised controlled trials comparing psychological therapies with pharmacological interventions for panic disorder with or without agoraphobia as diagnosed by operationalised criteria in adults. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data and resolved any disagreements in consultation with a third review author. For dichotomous data, we calculated risk ratios (RR) with 95% confidence intervals (CI). We analysed continuous data using standardised mean differences (with 95% CI). We used the random-effects model throughout. MAIN RESULTS We included 16 studies with a total of 966 participants in the present review. Eight of the studies were conducted in Europe, four in the USA, two in the Middle East, and one in Southeast Asia.None of the studies reported long-term remission/response (long term being six months or longer from treatment commencement).There was no evidence of a difference between psychological therapies and selective serotonin reuptake inhibitors (SSRIs) in terms of short-term remission (RR 0.85, 95% CI 0.62 to 1.17; 6 studies; 334 participants) or short-term response (RR 0.97, 95% CI 0.51 to 1.86; 5 studies; 277 participants) (very low-quality evidence), and no evidence of a difference between psychological therapies and SSRIs in treatment acceptability as measured using dropouts for any reason (RR 1.33, 95% CI 0.80 to 2.22; 6 studies; 334 participants; low-quality evidence).There was no evidence of a difference between psychological therapies and tricyclic antidepressants in terms of short-term remission (RR 0.82, 95% CI 0.62 to 1.09; 3 studies; 229 participants), short-term response (RR 0.75, 95% CI 0.51 to 1.10; 4 studies; 270 participants), or dropouts for any reason (RR 0.83, 95% CI 0.53 to 1.30; 5 studies; 430 participants) (low-quality evidence).There was no evidence of a difference between psychological therapies and other antidepressants in terms of short-term remission (RR 0.90, 95% CI 0.48 to 1.67; 3 studies; 135 participants; very low-quality evidence) and evidence that psychological therapies did not significantly increase or decrease the short-term response over other antidepressants (RR 0.96, 95% CI 0.67 to 1.37; 3 studies; 128 participants) or dropouts for any reason (RR 1.55, 95% CI 0.91 to 2.65; 3 studies; 180 participants) (low-quality evidence).There was no evidence of a difference between psychological therapies and benzodiazepines in terms of short-term remission (RR 1.08, 95% CI 0.70 to 1.65; 3 studies; 95 participants), short-term response (RR 1.58, 95% CI 0.70 to 3.58; 2 studies; 69 participants), or dropouts for any reason (RR 1.12, 95% CI 0.54 to 2.36; 3 studies; 116 participants) (very low-quality evidence).There was no evidence of a difference between psychological therapies and either antidepressant alone or antidepressants plus benzodiazepines in terms of short-term remission (RR 0.86, 95% CI 0.71 to 1.05; 11 studies; 663 participants) and short-term response (RR 0.95, 95% CI 0.76 to 1.18; 12 studies; 800 participants) (low-quality evidence), and there was no evidence of a difference between psychological therapies and either antidepressants alone or antidepressants plus benzodiazepines in terms of treatment acceptability as measured by dropouts for any reason (RR 1.08, 95% CI 0.77 to 1.51; 13 studies; 909 participants; very low-quality evidence). The risk of selection bias and reporting bias was largely unclear. Preplanned subgroup and sensitivity analyses limited to trials with longer-term, quality-controlled, or individual psychological therapies suggested that antidepressants might be more effective than psychological therapies for some outcomes.There were no data to contribute to a comparison between psychological therapies and serotonin-norepinephrine reuptake inhibitors (SNRIs) and subsequent adverse effects. AUTHORS' CONCLUSIONS The evidence in this review was often imprecise. The superiority of either therapy over the other is uncertain due to the low and very low quality of the evidence with regard to short-term efficacy and treatment acceptability, and no data were available regarding adverse effects.The sensitivity analysis and investigation of the sources of heterogeneity indicated three possible influential factors: quality control of psychological therapies, the length of intervention, and the individual modality of psychological therapies.Future studies should examine the long-term effects after intervention or treatment continuation and should provide information on risk of bias, especially with regard to selection and reporting biases.

Abstract
We report the current best estimate of the effects of cognitive behavior therapy (CBT) in the treatment of major depression (MDD), generalized anxiety disorder (GAD), panic disorder (PAD) and social anxiety disorder (SAD), taking into account publication bias, the quality of trials, and the influence of waiting list control groups on the outcomes. In our meta-analyses, we included randomized trials comparing CBT with a control condition (waiting list, care-as-usual or pill placebo) in the acute treatment of MDD, GAD, PAD or SAD, diagnosed on the basis of a structured interview. We found that the overall effects in the 144 included trials (184 comparisons) for all four disorders were large, ranging from g=0.75 for MDD to g=0.80 for GAD, g=0.81 for PAD, and g=0.88 for SAD. Publication bias mostly affected the outcomes of CBT in GAD (adjusted g=0.59) and MDD (adjusted g=0.65), but not those in PAD and SAD. Only 17.4% of the included trials were considered to be high-quality, and this mostly affected the outcomes for PAD (g=0.61) and SAD (g=0.76). More than 80% of trials in anxiety disorders used waiting list control groups, and the few studies using other control groups pointed at much smaller effect sizes for CBT. We conclude that CBT is probably effective in the treatment of MDD, GAD, PAD and SAD; that the effects are large when the control condition is waiting list, but small to moderate when it is care-as-usual or pill placebo; and that, because of the small number of high-quality trials, these effects are still uncertain and should be considered with caution.

Abstract
Flying phobia is a highly prevalent anxiety disorder, which causes sufferers significant distress and life interference. The processes which maintain flying phobia remain poorly understood. A systematic search of the literature was performed to identify what research has been conducted into the processes which may be involved in the fear of flying and whether processes which are believed to maintain other anxiety disorder diagnoses have been investigated in flying phobia. The results of the literature review are presented and related to existing cognitive behavioral theory and research. The results indicate that little research has been conducted into a number of areas considered important in the wider cognitive behavioral literature on anxiety disorders: namely attention, mental imagery, memory, worry, and safety-seeking behaviors. The review proposes a hypothetical model, derived from cognitive behavioral theory, for the processes which may be involved in maintaining flying phobia, and considers a number of areas for future research.

Abstract
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.

Abstract
There is growing interest in assessing the societal impacts of research such as informing health policies and clinical practice, and contributing to improved health. Bibliometric approaches have long been used to assess knowledge outputs, but can they also help evaluate societal impacts? We aimed to see how far the societal impacts could be traced by identifying key research articles in the psychiatry/neuroscience area and exploring their societal impact through analysing several generations of citing papers. Informed by a literature review of citation categorisation, we developed a prototype template to qualitatively assess a reference’s importance to the citing paper and tested it on 96 papers. We refined the template for a pilot study to assess the importance of citations, including self-cites, to four key research articles. We then similarly assessed citations to those citing papers for which the key article was Central i.e. it was very important to the message of the citing article. We applied a filter of three or more citation occasions in order to focus on the citing articles where the reference was most likely to be Central. We found the reference was Central for 4.4 % of citing research articles overall and ten times more frequently if the article contained three or more citation occasions. We created a citation stream of influence for each key paper across up to five generations of citations. We searched the Web of Science for citations to all Central papers and identified societal impacts, including international clinical guidelines citing papers across the generations.
