Cognitive behaviour therapy for posttraumatic stress disorder

Following considerable empirical scrutiny, cognitive behaviour therapy (CBT) has proven to be a safe and effective treatment for posttraumatic stress disorder (PTSD). This article overviews the general principles of treatment and describes the components that comprise CBT for PTSD. We then move on to review the efficacy of CBT for the treatment of PTSD caused by various traumas, including assault, road traffic accident (RTA), combat, and terrorism. Recent advances in early intervention and in the treatment of disorders that are comorbid with PTSD are reviewed. Finally, future directions are discussed. In particular, it is proposed that randomised controlled trials (RCT) of CBT for PTSD must be conducted with enhanced methodological rigour and public health relevance.     

Alternatives to debriefing and modifications to cognitive behavior therapy for posttraumatic stress disorder

BACKGROUND: Psychological debriefing uses brief unsystematic exposure, and is ineffective for posttraumatic stress symptoms and disorder. Systematic exposure alone and cognitive restructuring alone are each effective. Other approaches too may be useful. METHODS: The treatment of 3 posttraumatic stress disorder (PTSD) patients is detailed in which there was no exposure to the main traumatic event.There was exposure to related cues in case 1, exposure to related and other cues followed by well-being therapy (WBT) in case 2 and WBT in case 3. RESULTS: The 3 patients improved enduringly, confirming earlier findings that exposure to the main trauma is not essential for PTSD to improve. CONCLUSIONS: A study is needed of therapeutic mechanisms in PTSD and of the value of WBT in a randomized controlled trial.     

A randomized controlled trial of exposure therapy and cognitive restructuring for posttraumatic stress disorder

Previous studies have reported that adding cognitive restructuring (CR) to exposure therapy does not enhance treatment gains in posttraumatic stress disorder (PTSD). This study investigated the extent to which CR would augment treatment response when provided with exposure therapy. The authors randomly allocated 118 civilian trauma survivors with PTSD to receive 8 individually administered sessions of either (a) imaginal exposure (IE), (b) in vivo exposure (IVE), (c) IE combined with IVE (IE/IVE), or (d) IE/IVE combined with CR (IE/IVE/CR). There were fewer patients with PTSD in the IE/IVE/CR (31%) condition than the IE (75%), IVE (69%), and IE/IVE (63%) conditions at a 6-month follow-up assessment. The IE/IVE/CR condition resulted in larger effect sizes than each of the other conditions in terms of PTSD and depressive symptoms. These findings suggest that optimal treatment outcome may be achieved by combining CR with exposure therapy in treating PTSD patients.     

The cognitive psychology of Internet gaming disorder

Internet gaming disorder (IGD) has received nomenclatural recognition as a potential mental health disorder, despite evident variability in its core psychopathology and psychometric assessment. Although cognitive-behavioural therapy (CBT) is considered an efficacious treatment for IGD, the underlying cognitions of the disorder are not well understood. This review aimed to synthesise research evidence on Internet gaming cognition toward identification of cognitive factors underlying IGD. A systematic review of 29 quantitative studies on Internet gaming cognition and 7 treatment studies employing cognitive therapy for IGD was conducted. Four cognitive factors underlying IGD were identified. Factors included (a) beliefs about game reward value and tangibility, (b) maladaptive and inflexible rules about gaming behaviour, (c) over-reliance on gaming to meet self-esteem needs, and (d) gaming as a method of gaining social acceptance. It is proposed that IGD-related cognition may be more complex than “preoccupation” (i.e., criterion A of IGD). IGD cognition may involve the persistent overvaluation of video gaming rewards, activities, and identities, combined with a need to adhere to maladaptive rules governing use and completion of video games. Greater understanding of the proposed cognitive factors may advance clinical research agendas on identification of individuals with IGD, as well as the expansion and improvement of cognitive therapies for the disorder.     

A meta-analytic review of exposure in group cognitive behavioral therapy for posttraumatic stress disorder

Although the efficacy of exposure is well established in individual cognitive behavioral treatments for posttraumatic stress disorder (PTSD), some clinicians and researchers have expressed concerns regarding the use of in-session disclosure of trauma details through imaginal exposure in group cognitive behavioral therapy (GCBT) for PTSD. Thus, the aim of the present study was to conduct a systematic review of the empirical support for GCBT in the treatment of PTSD and to compare GCBT protocols that encourage the disclosure of trauma details via in-session exposure to GCBT protocols that do not include in-session exposure. Randomized controlled trials that assessed the efficacy of GCBT for PTSD were included in the meta-analysis. A total of 651 participants with PTSD were included in the 12 eligible GCBT treatment conditions (5 conditions included in-group exposure, 7 conditions did not include in-group exposure). The overall pre–post effect size of GCBT for PTSD (ES = 1.13 [SE = 0.22, 95% CI: 0.69 to 1.56, p  .001]). suggests that GCBT is an effective intervention for individuals with PTSD. No significant differences in effect sizes were found between GCBT treatments that included in-group exposure and those that did not. Although the attrition rate was higher in treatments that included exposure in-group, this rate is comparable to attrition rates in individual CBT treatments and pharmacotherapy for PTSD. The results from this meta-analysis suggest that concerns about the potentially negative impact of group exposure may be unwarranted, and support the use of exposure-based GCBT as a promising treatment option for PTSD.     

Culturally modified cognitive processing therapy for Karen refugees with posttraumatic stress disorder: A pilot study

Karen refugees, many originating from Myanmar, have suffered one of the longest civil wars in history and have thus witnessed and experienced substantial trauma. Refugees from Myanmar are currently one of the largest refugee groups being resettled in Western countries. This study investigated the feasibility and acceptability of a modified cognitive processing therapy (CPT) group program for Karen refugees with posttraumatic stress disorder (PTSD; N =7). It was found that the CPT program was well accepted, with high satisfaction and no drop‐outs. At posttreatment all participants no longer met PTSD diagnostic criteria and had a reliable improvement in PTSD symptoms when compared with pretreatment scores. At 3‐month follow‐up four participants (57% of sample) did not meet PTSD diagnostic criteria and three participants (43%) had a reliable improvement in PTSD symptoms when compared with pretreatment scores. However, at follow‐up four participants (57% of the sample) had a reliable worsening in PTSD symptoms when compared with their posttreatment PTSD symptom levels. Although the study found that the modified CPT was acceptable and feasible, future research is needed to develop and enhance strategies to ensure that refugees benefit from empirically supported treatments.     

Computerised cognitive behaviour therapy for obsessive-compulsive disorder: a systematic review

BACKGROUND: Computer-guided therapy is an innovative treatment strategy that could have an important role in the future of psychological treatment. This paper summarises the available published evidence that assesses the effectiveness of a computerised cognitive behaviour therapy (CCBT) for obsessive-compulsive disorder (OCD). METHODS: Fifteen electronic bibliographic databases including Medline, Embase, the Cochrane Library, Cinahl, PsycINFO, Biological Abstracts, HMIC and NHS CRD databases were comprehensively searched in March 2004: ['obsessive compulsive disorder' (text and indexed terms)] AND ['cognitive therapy' (text and indexed terms)] AND ['computer' (text and indexed terms)]. Reference lists of included studies, guidelines, generic research, trials registers and specialist mental health sites were hand-searched. RESULTS: The search produced 149 citations from which we identified two RCTs and two single-arm studies with relevant data. All four studies used one software programme - BTSteps.In the large RCT, YBOCS effect sizes for BTSteps, therapist-led cognitive behaviour therapy (TCBT) and relaxation (RLX) were 0.84, 1.22, and 0.35, respectively. The smaller RCT found significantly better outcomes with brief scheduled support compared to brief on-demand phone support. CONCLUSIONS: BTSteps was as good as TCBT for reducing time spent in rituals and obsessions and for improving the Work and Social Adjustment Scale (WSA), and was superior to RLX treatment. The available evidence also showed that improvement of OCD persisted beyond the end of CCBT. TCBT was more effective than CCBT for all patients overall though not in those who went on to start self-exposure. Such a system has the potential to widen the access to CBT in general and considerably shorten clinician-guided care.     

A randomized trial of cognitive therapy and imaginal exposure in the treatment of chronic posttraumatic stress disorder

A randomized trial was performed in which imaginal exposure (IE) and cognitive therapy (CT) were compared in the treatment of chronic posttraumatic stress disorder (PTSD). Patients who continued to meet PTSD caseness at the end of a 4-week symptom-monitoring baseline period (n = 72) were randomly allocated to either IE or CT. There was a significant improvement in all measures over treatment and at follow-up, although there were no significant differences between the 2 treatments at any assessment. A significantly greater number of patients who showed worsening over treatment received IE, although this effect was not found at follow-up. Patients who worsened showed a greater tendency to miss treatment sessions, rated therapy as less credible, and were rated as less motivated by the therapist. It was concluded that either exposure or a challenge to cognition can result in symptom reduction, although neither resulted in complete improvement.     

An integrative complexity analysis of cognitive behaviour therapy sessions for borderline personality disorder

Objectives . Integrative complexity (IC), a measure of cognitive style, was used to analyse discourse in Cognitive Behaviour Therapy (CBT) sessions from patients with borderline personality disorder treated in the BOSCOT trial. It was predicted that patients' level of integrative complexity would be positively associated with the outcome of therapy. That is, an increase in patients' level of integrative complexity would be associated with good outcome. We also predicted that therapists would also show an increase in the level of complexity associated with their patient's increase in integrative complexity and good outcome. Design . Ten patients who received CBT were categorized according to the outcome, good (N=5) and poor (N=5), using an algorithm that incorporated the number of suicide attempts and magnitude of change in severity of depression during therapy. Method . For each patient and their therapist, an early and a late therapy session were transcribed and coded for integrative complexity (IC) (N=20 sessions transcribed). IC scores for patients and therapists were compared across early and late therapy sessions and for good and poor outcomes of therapy. Results . The majority of discourse was at the lower levels of IC. Higher levels of IC at baseline were related to depression and anxiety. Good outcome was not associated with a change in the level of IC between earlier and later CBT sessions. Therapists, however, showed an increase in IC when patient's outcome was poor. In addition, an increase in patient's IC was associated with improvement in social functioning. Conclusions . Therapists may overcompensate for patient's poor outcome by giving more complex explanations to patients. Higher complexity does not necessarily lead to better outcomes.     

Cognitive processing therapy for veterans with military-related posttraumatic stress disorder

Sixty veterans (54 men, 6 women) with chronic military-related posttraumatic stress disorder (PTSD) participated in a wait-list controlled trial of cognitive processing therapy (CPT). The overall dropout rate was 16.6% (20% from CPT, 13% from waiting list). Random regression analyses of the intention-to-treat sample revealed significant improvements in PTSD and comorbid symptoms in the CPT condition compared with the wait-list condition. Forty percent of the intention-to-treat sample receiving CPT did not meet criteria for a PTSD diagnosis, and 50% had a reliable change in their PTSD symptoms at posttreatment assessment. There was no relationship between PTSD disability status and outcomes. This trial provides some of the most encouraging results of PTSD treatment for veterans with chronic PTSD and supports increased use of cognitive- behavioral treatments in this population.     

Therapist contact in cognitive behaviour therapy for panic disorder and agoraphobia in primary care

Panic disorder with or without agoraphobia is a prevalent clinical disorder which places heavy demands on treatment resources in primary care. The efficiency of delivery of psychological treatments for this disorder is therefore important. Previous research has focused on psychological treatments delivered with reduced therapist contact but methodological problems preclude firm conclusions. The present study investigated the relevance of therapist contact in cognitive behaviour therapy for panic disorder and agoraphobia, taking account of previous methodological problems. One hundred and four patients suffering from DSM III‐R panic disorder with or without agoraphobia were randomly allocated to receive cognitive behaviour therapy with either, ‘standard’ therapist contact, ‘minimum’ therapist contact or as a bibliotherapy. All patients were seen by the same therapist and all received an identical treatment manual. Treatment response, as measured by patient and therapist report scales of anxiety, depression, and agoraphobic avoidance, was analysed in terms of both traditional statistical significance and clinical significance of outcome. At treatment end‐point the ‘standard’ therapist contact and ‘minimum’ therapist contact groups showed significant reductions pre‐ to post‐treatment on all measures. Pre‐ to post‐treatment reductions for the bibliotherapy group were significant on therapist‐ and patient‐rated measures of anxiety only. The ‘standard’ therapist contact group was consistently significantly improved in comparison to the bibliotherapy group. Significant differences between the ‘standard’ and ‘minimum’ therapist contact groups were found on therapist‐rated anxiety only. Assessment of clinical significance of treatment outcome showed further differences between treatment groups with the ‘standard’ therapist contact group showing the largest proportion of patients achieving clinically significant change on all measures both at treatment end‐point and at 6‐month follow‐up.

A pilot study of cognitive behaviour therapy for panic disorder augmented by panic surfing

This pilot study reports the outcome of cognitive behaviour therapy for panic disorder augmented by panic surfing. This treatment approach encourages acceptance of feelings rather than control of symptoms and anxiety, at the same time also targeting catastrophic misinterpretations, bodily vigilance and safety‐seeking behaviours. Eighteen participants completed a brief group treatment for panic disorder incorporating psychoeducation, panic surfing, interoceptive exposure, graded exposure and cognitive restructuring. Significant improvements occurred over the course of this treatment and were maintained at a 1‐month follow‐up. Results suggest that cognitive behaviour therapy augmented by panic surfing may be effective in the treatment of panic disorder, but there is a need for controlled studies and investigation of the relative contribution of its various components.

Imaginal exposure alone and imaginal exposure with cognitive restructuring in treatment of posttraumatic stress disorder

This study investigated the extent to which providing cognitive restructuring (CR) with prolonged imaginal exposure (IE) would lead to greater symptom reduction than providing IE alone for participants with posttraumatic stress disorder (PTSD). Fifty-eight civilian survivors of trauma with PTSD were randomly allocated to IE/CR, IE, or supportive counseling (SC). Treatment involved 8 individual weekly sessions with considerable homework. Independent assessments were conducted pretreatment, posttreatment, and at 6-month follow-up. IE/CR and IE resulted in reduced PTSD and depression compared with SC at posttreatment and follow-up. Further, IE/CR participants had greater reductions in PTSD and maladaptive cognitive styles than IE participants at follow-up. These findings suggest that providing CR in combination with IE may enhance treatment gains.     

Group cognitive behaviour therapy for adults with Asperger syndrome and anxiety or mood disorder: a case series

Individuals with Asperger syndrome are at increased risk for mental health problems compared with the general population, especially with regard to mood and anxiety disorders. Generic mental health services are often ill‐equipped to offer psychotherapeutic treatments to this population, and specialized supports are difficult to find. This case series used a manualized cognitive behaviour therapy group programme (Mind Over Mood) with three adults diagnosed with Asperger syndrome, who were each unable to access psychotherapy through mainstream mental health services. This review highlights the benefits of a cognitive behaviour therapy (CBT) group approach for adults with Asperger syndrome and suggests some potential modifications to traditional CBT provision. Copyright © 2010 John Wiley & Sons, Ltd. Key Practitioner Message: ? As a group, adults with Asperger syndrome are at high risk for anxiety disorders and depression. ? Cognitive behaviour therapy can be adapted to help adults with Asperger syndrome cope with anxiety or depression. ? Group cognitive behaviour therapy for adults with Asperger syndrome may hold a number of advantages to individual therapy.
