Clinical effectiveness of a cognitive behavioral group treatment program for anxiety disorders: A benchmarking study

Previous research has established efficacy of cognitive behavioral therapy (CBT) for anxiety disorders, yet it has not been widely assessed in routine community clinic practices. Efficacy research sacrifices external validity to achieve maximum internal validity. Recently, effectiveness research has been advocated as more ecologically valid for assessing routine clinical work in community clinics. Furthermore, there is a lack of effectiveness research in group CBT. This study aims to extend existing research on the effectiveness of CBT from individual therapy into group therapy delivery. It aimed also to examine outcome using not only symptom measures, but also measures of related symptoms, cognitions, and life quality and satisfaction. Results from a cohort of patients with various anxiety disorders demonstrated that treatment was effective in reducing anxiety symptoms to an extent comparable with other effectiveness studies. Despite this, only 43% of individuals showed reliable change, and 17% were ‘recovered’ from their anxiety symptoms, and the post-treatment measures were still significantly different from the level of anxiety symptoms observed in the general population.     

Motivational interviewing and cognitive behaviour therapy for anxiety following traumatic brain injury: A pilot randomised controlled trial

Although cognitive-behavioural therapy (CBT) is the treatment of choice for anxiety, its delivery needs to be adapted for individuals with traumatic brain injury (TBI). It also requires clients' active engagement for maximum benefit. This study was a pilot randomised controlled trial involving an anxiety treatment programme adapted for people with TBI, based on CBT and motivational interviewing (MI). Twenty-seven participants with moderate/severe TBI (aged 21–73 years, 78% males) recruited from a brain injury rehabilitation hospital were randomly allocated to receive MI?+?CBT (n?=?9), non-directive counselling (NDC)?+?CBT (n?=?10) and treatment-as-usual (TAU) (n?=?8). CBT and MI were manualised and delivered in 12 weekly individual sessions. Primary outcome was self-reported anxiety symptoms assessed at baseline, at the end of NDC/MI and immediately following CBT. Assessment was conducted by assessors blinded to group assignment. Intention-to-treat analyses showed that the two active treatment groups demonstrated significantly greater anxiety reduction than TAU. Participants receiving MI showed greater response to CBT, in terms of reduction in anxiety, stress and non-productive coping, compared to participants who received NDC. The results provided preliminary support for the adapted CBT programme, and the potential utility of MI as treatment prelude. Longer follow-up data are required to evaluate the maintenance of treatment effects.     

Elements of the therapeutic relationship in CBT for anxiety disorders: A systematic review

To optimise the effects of cognitive behaviour therapy (CBT) for anxiety disorders, research has increasingly focussed on understanding mechanisms of change. Specifically, the therapeutic relationship has been identified as a potential “active ingredient” of therapy. The evidence for the effects of eleven elements of the therapeutic relationship (alliance, collaboration, goal consensus, group cohesion, empathy, positive regard, feedback, emotional expression, outcome expectations, treatment credibility, alliance rupture-repair) on treatment outcomes in CBT for anxiety disorders was systematically reviewed. Fifty unique studies were included, and findings were qualitatively reviewed and summarised. Results revealed consistent and sizeable evidence for the cohesion-outcome and expectation-outcome relationships. There was emerging evidence for the effects of collaboration, empathy, and alliance rupture-repair on outcomes. However, the evidence for goal consensus and credibility on outcomes was limited. Notably, review of the alliance literature revealed substantial inconsistencies across studies. No studies were identified for positive regard, feedback, and emotional expression. Overall, further research is needed to clarify the role of the therapeutic relationship in CBT for anxiety disorders. These findings will contribute to the conceptual integration of therapeutic relationship constructs in cognitive behavioural models, and help to improve treatments and outcomes for individuals.     

Psychoeducation for major depressive disorders: A randomised controlled trial

Various psychological therapies have been shown to be effective for the treatment of mood disorders. Among them, family psychoeducation has demonstrated efficacy in reducing symptom severity and extending the time to relapse. We tested the efficacy of adding psychoeducation focussed on how to deal with the family's expressed emotion to treatment as usual (TAU) to prevent relapse among patients with remitted major depression. A total of 34 patients with major depressive disorders in full or partial remission were randomised to receive either group psychoeducation over six sessions, each consisting of a didactic lecture and group problem-solving (n=19), plus TAU or TAU alone (n=15). The primary outcome was relapse by Diagnostic and Statistical Manual of Mental Disorders fourth edition (DSM–IV) criteria. Masked raters administered the Hamilton Rating Scale for Depression-17 (HRSD-17). As many as 18 patients in the intervention group and 14 patients in the control group completed the study. Time to relapse was significantly longer in the intervention group than in the control group, with a risk ratio (RR) of relapse by 9 months of 0.12. At 9 months, there was a significantly greater decrease in the HRSD-17 score in the intervention group than in the control group. We demonstrated the effectiveness of patient psychoeducation on the course and outcome of major depressive disorders.     

Cognitive behavioural techniques reduce exercise anxiety and improve adherence to a resistance training program for people with anxiety-related disorders: A randomized controlled trial

Exercise is a cost-efficient alternative to other interventions for anxiety-related disorders (ARDs; e.g., psychotherapy, pharmaceutical) that is also associated with health benefits. Several exercise modalities, including resistance training (RT), have demonstrated efficacy at reducing symptoms of ARDs; however, there are challenges associated with effectively implementing such protocols, most notably, exercise avoidance or early discontinuation. Researchers have identified exercise anxiety as a contributor to exercise avoidance for people with ARDs. Exercise-based interventions for people with ARDs may need to include strategies for helping these individuals cope with exercise anxiety to facilitate long-term exercise engagement; however, research in this area is lacking. The primary purpose of this randomized controlled trial (RCT) was to examine the effects of combining cognitive behavioural techniques (CBT) with a RT program on changes in exercise anxiety, exercise frequency, disorder-specific anxiety symptoms, and physical activity for people with ARDs. A secondary purpose was to explore group differences in exercise motivation and exercise self-efficacy across time. A total of 59 physically inactive individuals with ARDs were randomized into either RT + CBT, RT, or waitlist (WL). Primary measures were assessed at baseline, weekly during the 4-week active phase, and at 1-week, 1-month, and 3-month follow-ups. Findings indicate both RT and RT + CBT can reduce exercise anxiety; however, the addition of CBT techniques may help facilitate improvements in exercise self-efficacy, reductions in disorder-specific anxiety, and increases in long-term exercise behaviour and vigorous physical activity. These techniques may be useful for researchers and clinicians alike in supporting individuals with ARDs interested in using exercise to cope with elevated anxiety.     

A randomised controlled trial of a worry intervention for individuals with persistent persecutory delusions

Recent research has shown that worry is associated with distressing paranoia. Therefore, the aim was to target worry in a therapeutic intervention for individuals with delusions. It was predicted that a worry intervention would reduce levels of worry and paranoia distress. Twenty-four individuals with persistent persecutory delusions and high levels of worry were randomly assigned to receive a four session cognitive-behavioural worry intervention (W-CBT) or treatment as usual (TAU). The worry intervention was specifically designed not to target the content of delusions. In this open-label evaluation, assessments of worry and paranoia were conducted at baseline, at one month (end of treatment) and at two months. The worry intervention achieved a statistically significant reduction in worry which was maintained at two month follow up. A significant reduction in delusional distress was also reported. There was an indication that the worry intervention may also reduce the frequency of paranoid thoughts but this was not statistically significant. In the first trial specifically for persecutory delusions, a brief worry intervention was shown to have benefits. The results support a causal role for worry in paranoid experience.     

Cognitive functioning in a population-based sample of young adults with anxiety disorders

Objective

Cognitive functioning in anxiety disorders has received little investigation, particularly among young adults and in non-clinical samples. The present study examined cognitive functioning in a population-based sample of young adults with anxiety disorders in comparison to healthy peers.

Methods

A population-based sample of 21–35-year-olds with a lifetime history of anxiety disorders (n = 75) and a random sample of healthy controls (n = 71) derived from the same population were compared in terms of performance in neuropsychological tests measuring verbal and visual short-term memory, verbal long-term memory, attention, psychomotor processing speed, and executive functioning.

Results

In general, young adults with anxiety disorders did not have major cognitive impairments when compared to healthy peers. When participants with anxiety disorder in remission were excluded, persons with current anxiety disorder scored lower in visual working memory tests. Current psychotropic medication use and low current psychosocial functioning associated with deficits in executive functioning, psychomotor processing speed, and visual short-term memory.

Conclusion

Lifetime history of anxiety disorders is not associated with cognitive impairment among young adults in the general population. However, among persons with anxiety disorders, current psychotropic medication use and low psychosocial functioning, indicating more severe symptoms, may associate with cognitive impairments.     

Orexin A in adolescents with anxiety disorders

Abstract

Objectives: The relationships between orexins and stress-related conditions have been well documented in animal studies. However, human studies confirming this relationship are limited. The aim of this study was to investigate the association between orexin-A and anxiety disorders in adolescents. Additionally, we aimed to examine the relationship between orexin-A and cortisol levels in those with anxiety disorders.

Methods: A total of 56 medication-free adolescents diagnosed with any anxiety disorder, except for specific phobias, and 32 healthy controls were included in this study. Depression, state and trait anxiety levels of the participants were measured using self-report scales. Orexin-A and cortisol levels were measured by an enzyme-linked immunosorbent assay (ELISA).

Results: Analysis of covariance (ANCOVA) indicated that serum orexin-A levels were significantly higher in the anxiety disorder group than in the control group while controlling for age, sex and depression levels. After controlling for age and sex, orexin-A levels were positively and negatively correlated to depression and cortisol levels, respectively. In addition, a positive correlation trend between trait anxiety and orexin-A was found.

Conclusions: Orexin-A levels are higher in adolescents with anxiety disorder; however, depressive symptoms should be considered when investigating this relationship.     

The effect of comorbid substance use disorders on treatment outcome for anxiety disorders

This study examined the impact of concurrent substance use disorders (SUDs) on outcomes for psychotherapy targeting anxiety disorders. Study 1 (N=484) sought to determine the prevalence of SUDs in a sample referred to a community anxiety disorders clinic, as well as the impact of comorbid SUDs on outcomes for a subsample (n=200) completing cognitive behavior therapy (CBT). Around one-quarter (22-29%) of patients with one or two anxiety disorders met criteria for at least one SUD, but this rate was substantially higher (46%) for patients with three anxiety disorders. Concurrent SUDs were associated with higher levels of anxiety but not depression or stress, compared to those without a SUD. However, concurrent SUDs did not moderate treatment outcomes. Study 2 (N=103) focused on the impact of alcohol use on diagnosis-specific symptom measures and generic measures of distress and disability, following a course of CBT for panic disorder or social phobia. Pre-treatment alcohol use did not predict changes in panic symptoms, performance anxiety, distress, or disability, but it did predict changes in social interaction anxiety. Problem drinking per se did not have any predictive utility in terms of treatment outcome. These findings suggest that clinicians treating patients for a primary anxiety disorder and concurrent SUD can be relatively optimistic about treatment outcomes.     

Alterations of the attentional networks in patients with anxiety disorders

Cognitive theories of emotion try to explain how anxious people attend to the world. Despite the increase in empirical research in this field, the specific or general attentional impairments of patients with anxiety disorder is not well defined. We decided to investigate the relationship between pathological anxiety and attentional mechanisms from the broader perspective of the attentional networks. In our study, patients with anxiety disorders and control participants carried out a task to assess efficiency of three attentional networks: orienting, alerting, and executive control. The main result was that anxiety disorders are related to both reduced effectiveness of the executive control network and difficulties in disengaging attention from invalid cues, even when using emotionally neutral information. This relationship between these attentional networks and anxiety may in part explain the problems in the day-to-day functioning of these patients.     

CHAMP: Cognitive behaviour therapy for health anxiety in medical patients, a randomised controlled trial

Background

Suicide attempts (SA) constitute a serious clinical problem. People who attempt suicide are at high risk of further repetition. However, no interventions have been shown to be effective in reducing repetition in this group of patients.

Methods/Design

Multicentre randomized controlled trial. We examine the effectiveness of «ALGOS algorithm»: an intervention based in a decisional tree of contact type which aims at reducing the incidence of repeated suicide attempt during 6 months. This algorithm of case management comprises the two strategies of intervention that showed a significant reduction in the number of SA repeaters: systematic telephone contact (ineffective in first-attempters) and «Crisis card» (effective only in first-attempters). Participants who are lost from contact and those refusing healthcare, can then benefit from «short letters» or «postcards».

Discussion

ALGOS algorithm is easily reproducible and inexpensive intervention that will supply the guidelines for assessment and management of a population sometimes in difficulties with healthcare compliance. Furthermore, it will target some of these subgroups of patients by providing specific interventions for optimizing the benefits of case management strategy.

Trial Registration

The study was registered with the ClinicalTrials.gov Registry; number: NCT01123174.     

Personality disorders and the persistence of anxiety disorders: Evidence of a time-of-measurement effect in NESARC

Recent studies using data from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) have found that some personality disorders (PDs) increase the persistence of several Axis I disorders. However, these effects are potentially confounded with the data collection wave in which PDs were assessed. Our aim was to extend published analyses to the case of anxiety disorders and to determine the robustness of the associations to analyses examining time-of-measurement effects. Persistence of anxiety disorders was defined either as follow-up diagnosis among participants diagnosed at baseline (“prediction”) or baseline diagnosis among participants diagnosed at follow-up (“post-diction”). Results revealed a robust pattern of higher odds ratios for post-diction among PDs assessed at baseline, and lower odds ratios for post-diction among PDs assessed at follow-up, suggesting a time of measurement artifact. Although only 4% of associations were robust to both predictive and post-dictive analyses, these were consistent with previous research.     

The role of depression in perceived parenting style among patients with anxiety disorders

Despite a long tradition of research on the relationship between parenting style and anxiety disorders, few studies have taken the effect of comorbid depression into account. This study investigated perceived parenting in 504 outpatients with panic disorder/agoraphobia, social phobia or obsessive–compulsive disorder, and in 210 psychology students. The anxiety group reported both parents as less caring and their fathers as more controlling than did the student group. However, these between-group differences disappeared when taking self-reported depressive symptoms into consideration. Also no differences in parental style were found between the three diagnostic anxiety groups, when depressive symptoms were taken into account. Self-reported depressive symptoms were more consistently associated with negatively perceived parenting style than with self-reported anxiety symptoms in both the anxiety group and the student group. Results do not support theories of parental control as a specific risk factor for anxiety disorders, but they are in accordance with prior findings showing an association between depression and perceived lack of parental care.     

Attention Bias Modification Treatment for children with anxiety disorders who do not respond to cognitive behavioral therapy: a case series

Evidence is emerging to support the promise of Attention Bias Modification Treatment (ABMT), a computer-based attention training program, in reducing anxiety in children. ABMT has not been tested as an adjuvant for children with anxiety disorders who do not respond to Cognitive-Behavioral Therapy (CBT). This case series presents findings from an open trial of ABMT among six children (four girls; M age = 11.2 years) who completed a CBT protocol and continued to meet diagnostic criteria for an anxiety disorder. All children completed the ABMT protocol with no canceled or missed sessions. Child self-ratings on anxiety symptoms and depressive symptoms significantly decreased from pretreatment to posttreatment, as did parent ratings on child anxiety-related impairment. Parent ratings on child anxiety and internalizing symptoms displayed non-significant decreases from pretreatment to posttreatment. These findings support the potential promise of ABMT as a feasible adjuvant treatment that reduces anxiety and impairment among child anxiety CBT nonresponders.     

The prevalence and clinical implications of self-medication among individuals with anxiety disorders

Alcohol dependence (AD) is more likely to occur among individuals with rather than without an anxiety disorder. Self-medication theory (SMT) holds that drinking behavior is negatively reinforced when alcohol temporarily reduces anxiety and that the resulting escalation of drinking increases the risk for AD. We set out to empirically scrutinize SMT using the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) dataset. We found that only a minority (about 20%) of anxiety disordered individuals endorsed drinking to control anxiety symptoms. This minority drank more alcohol, had a higher cross-sectional rate of AD, and was at higher risk for developing new AD over four years compared to anxiety disordered non-self-medicators and individuals with no anxiety disorder. Consistent with SMT, increased prospective risk for AD among self-medicators is partially mediated by an increased level of alcohol use. Understanding the processes that promote and inhibit self-medication should be a priority for anxiety disorder researchers.     

The prevalence of depression and anxiety disorders in patients with euthyroid Hashimoto’s thyroiditis: a comparative study

Objective

The aim of this study was to examine the current prevalence of major depression and anxiety disorders in patients with euthyroid Hashimoto’s thyroiditis (HT) and euthyroid goiter.

Method

The study sample was formed by consecutive 51 and 45 patients who were admitted to the endocrinology outpatient clinic and diagnosed with euthyroid HT and endemic/nonendemic goiter, respectively, and 68 healthy controls. Current diagnoses of psychiatric disorders were determined using the Structured Clinical Interview for DSM-IV. Beck Depression Inventory and Beck Anxiety Inventory were applied to the participants.

Results

There was a statistically significant difference among the three groups in terms of major depression (P=.001), any mood or anxiety disorder (P=.000), any depressive disorder (P=.020), any anxiety disorder (P=.016) and obsessive–compulsive disorder (OCD) (P=.013). In the HT group, the prevalence of depression (P=.000), OCD (P=.005) and panic disorder (P=.041) was significantly higher than that in the control group. In the goiter group, depression (P=.006), any depressive disorder (P=.03), and any mood or anxiety disorder (P=.000) were significantly common in comparison to the control group. No significant difference was found between the HT and goiter groups.

Conclusions

Euthyroid HT and euthyroid goiter increase predisposition to major depression and anxiety disorders, and thyroid autoimmunity and other thyroid pathologies should be investigated in euthyroid patients with chronic and treatment-resistant complaints.
