Media-delivered cognitive behavioural therapy and behavioural therapy (self-help) for anxiety disorders in adults.

BACKGROUND: Anxiety disorders are the most common mental health problems. They are chronic and unremitting. Effective treatments are available, but access to services is limited. Media-delivered behavioural and cognitive behavioural interventions (self-help) aim to deliver treatment with less input from professionals compared with traditional therapies. OBJECTIVES: To assess the effects of media-delivered behavioural and cognitive behavioural therapies for anxiety disorders in adults. SEARCH METHODS: Published and unpublished studies were considered without restriction by language or date. The Cochrane Depression, Anxiety and Neurosis Review Group's Specialized Register (CCDANCTR) was searched all years to 1 January 2013. The CCDANCTR includes relevant randomised controlled trials from the following bibliographic databases: The Cochrane Library (all years), EMBASE (1974 to date), MEDLINE (1950 to date) and PsycINFO (1967 to date). Complementary searches were carried out on Ovid MEDLINE (1950 to 23 February 2013) and PsycINFO (1987 to February, Week 2, 2013), together with International trial registries (the trials portal of the World Health Organization (ICTRP) and ClinicalTrials.gov). Reference lists from previous meta-analyses and reports of randomised controlled trials were checked, and authors were contacted for unpublished data. SELECTION CRITERIA: Randomised controlled trials of media-delivered behavioural or cognitive behavioural therapy in adults with anxiety disorders (other than post-traumatic stress disorder) compared with no intervention (including attention/relaxation controls) or compared with face-to-face therapy. DATA COLLECTION AND ANALYSIS: Both review authors independently screened titles and abstracts. Study characteristics and outcomes were extracted in duplicate. Outcomes were combined using random-effects models, and tests for heterogeneity and for small study bias were conducted. We examined subgroup differences by type of disorder, type of intervention provided, type of media, and recruitment methods used. MAIN RESULTS: One hundred and one studies with 8403 participants were included; 92 studies were included in the quantitative synthesis. These trials compared several types of media-delivered interventions (with varying levels of support) with no treatment and with face-to-face interventions. Inconsistency and risk of bias reduced our confidence in the overall results. For the primary outcome of symptoms of anxiety, moderate-quality evidence showed medium effects compared with no intervention (standardised mean difference (SMD) 0.67, 95% confidence interval (CI) 0.55 to 0.80; 72 studies, 4537 participants), and low-quality evidence of small effects favoured face-to-face therapy (SMD -0.23, 95% CI -0.36 to -0.09; 24 studies, 1360 participants). The intervention was associated with greater response than was seen with no treatment (risk ratio (RR) 2.34, 95% CI 1.81 to 3.03; 21 studies, 1547 participants) and was not significantly inferior to face-to-face therapy in these studies (RR 0.78, 95 % CI 0.56 to 1.09; 10 studies, 575 participants), but the latter comparison included versions of therapies that were not as comprehensive as those provided in routine clinical practice. Evidence suggested benefit for secondary outcome measures (depression, mental-health related disability, quality of life and dropout), but this evidence was of low to moderate quality. Evidence regarding harm was lacking. AUTHORS' CONCLUSIONS: Self-help may be useful for people who are not able or are not willing to use other services for people with anxiety disorders; for people who can access it, face-to-face cognitive behavioural therapy is probably clinically superior. Economic analyses were beyond the scope of this review.Important heterogeneity was noted across trials. Recent interventions for specific problems that incorporate clinician support may be more effective than transdiagnostic interventions (i.e. interventions for multiple disorders) provided with no guidance, but these issues are confounded in the available trials.Although many small trials have been conducted, the generalisability of their findings is limited. Most interventions tested are not available to consumers. Self-help has been recommended as the first step in the treatment of some anxiety disorders, but the short-term and long-term effectiveness of media-delivered interventions has not been established. Large, pragmatic trials are needed to evaluate and to maximise the benefits of self-help interventions.

The role of dental therapists in pharmacological and non-pharmacological treatment of anxious and phobic patients.

Dental Therapists are in a prime position to be involved with the management of anxious and phobic patients. They earn less than dentists and are therefore a more cost-effective way of providing specialised care for anxious patients. Dental Therapists can spend more time educating and acclimatising these patients, do most if not all of the patient's treatment, only referring back to the dentist for RCT, crown/bridgework/dentures and permanent extractions. Ultimately this means that the patient receives high quality continuity of care. Treating anxious and phobic patients is time-consuming but ultimately very rewarding. If handled correctly and sensitively the anxious and phobic patient will not always be anxious or phobic, in the same way that children won't always be children. Dental Therapists can now extend their duties to include Relative Analgesia. This should enhance their employability and role within the dental team especially in the management of anxious and phobic patients. Employing a therapist with a toolbox of techniques at their disposal can be seen as part of a long-term practice plan to ensure that anxious and phobic patients become rehabilitated, happy, compliant and loyal to the practice! In fact .... the sort of patients every dentist really wants to see.

Home oral health practice: the foundation for desensitization and dental care for special needs.

As oral health is increasingly recognized as a foundation for health and wellness, caregivers for special needs patients are an essential component of the oral health team and must become knowledgeable and competent in home oral health practice. Education and training for caregivers should become a standard of care early in the first year of life for any child with developmental delay or any person, regardless of age, who experiences an illness or event that compromises their ability to provide self oral health care. Given the implication of poor oral health to general health and health care costs, home oral health practice is a significant factor in dental care, general health, quality of life, and controlling health care costs.

Practitioner review: assessment and treatment of refugee children and adolescents who have experienced war-related trauma.

BACKGROUND: Increasingly clinicians are being asked to assess and treat young refugees, who have experienced traumatic events due to war and organised violence. However, evidence-based guidance remains scarce. METHOD: Published studies on the mental health difficulties of refugee children and adolescents, associated risk and protective factors, as well as effective interventions, particularly those designed to reduce war-related post-traumatic stress disorder (PTSD) symptoms, were identified and reviewed. The findings are summarised. RESULTS: Young refugees are frequently subjected to multiple traumatic events and severe losses, as well as ongoing stressors within the host country. Although young refugees are often resilient, many experience mental health difficulties, including PTSD, depression, anxiety and grief. An awareness of relevant risk and protective factors is important. A phased model of intervention is often useful and the need for a holistic approach crucial. Promising treatments for alleviating symptoms of war-related PTSD include cognitive behavioural treatment (CBT), testimonial psychotherapy, narrative exposure therapy (NET) and eye movement desensitisation and reprocessing (EMDR). Knowledge of the particular needs of unaccompanied asylum-seeking children (UASC), working with interpreters, cross-cultural differences, medico-legal report writing and the importance of clinician self-care is also necessary. CONCLUSION: More research is required in order to expand our limited knowledge base.

A review of gagging problems in dentistry: 2. Clinical assessment and management.

A pronounced gag reflex can be a severe limitation to a patient's ability to accept dental care and for a clinician's ability to provide it. It can compromise all aspects of dentistry from diagnostic procedures to active treatment and can be distressing for all concerned. Many 'management' techniques have been described. This paper describes the different categories of treatment used to manage people with pronounced gag reflexes.

Validity and reliability study of three tinnitus self-assessment scales: loudness, annoyance and change.

CONCLUSIONS: The three tinnitus self-rating scales described herein can be employed as part of "minimal datasets" to reflect the patient's current tinnitus status. These tests are simple and easy to use and can be completed by the patient alone. The results are easy to interpret and provide a good foundation for an effective doctor-patient dialogue. OBJECTIVE: To investigate the reliability and validity of three tinnitus self-rating scales: a six-point response scale for tinnitus loudness; an eight-point response scale for tinnitus annoyance; and a six-point response scale for tinnitus change. MATERIAL AND METHODS: The data for 273 patients participating in 2 separate studies were assessed in terms of their validity and reliability. We used criterion validity to determine whether the scales had empirical associations with external criteria, in this case an already firmly established tinnitus questionnaire. In addition we examined construct validity, i.e. its subcategories convergent and discriminant validity, in order to find out how related or unrelated items or scales were. We tested the reliability and repeatability of the scales using patients on our waiting list for tinnitus desensitization. RESULTS: The test-retest reliability was 0.72 for tinnitus loudness and 0.62 for tinnitus annoyance. Calculations showed that all three scales correlated positively with validated complex scales and thus we considered convergent validity to be adequate.

A review of self-management interventions for panic disorders, phobias and obsessive-compulsive disorders.

OBJECTIVE: To review current evidence for the clinical and cost-effectiveness of self-management interventions for panic disorder, phobias and obsessive-compulsive disorder (OCD). METHOD: Papers were identified through computerized searches of databases for the years between 1995 and 2003, manual searches and personal contacts. Only randomized-controlled trials were reviewed. RESULTS: Ten studies were identified (one OCD, five panic disorder, four phobias). Effective self-management interventions included cognitive-behavioural therapy (CBT) and exposure to the trigger stimuli for phobias and panic disorders. All involved homework. There was evidence of effectiveness in terms of improved symptoms and psychological wellbeing when compared with standard care, waiting list or relaxation. Brief interventions and computer-based interventions were effective for most participants. In terms of quality, studies were mainly based on small samples, lacked long-term follow-up, and failed to address cost-effectiveness. CONCLUSION: Despite the limitations of reviewed studies, there appears to be sufficient evidence to warrant greater exploration of self-management in these disorders.

Oral health for people with intellectual disability and high support needs: positive outcomes.

This qualitative study, based on phenomenological approaches, explored and documented four situations in which positive oral health outcomes occurred for people with mental retardation and moderate to high support needs. Strategies and environmental factors that contributed to these oral health outcomes were identified through 10 semistructured interviews conducted with 'key-players' supporting the oral health of the people with disabilities. Participants included dental professionals, direct support workers, and other professionals who cared for their four people with disabilities. Common strategies expressed in the interviews included "giving it a go"; maintaining consistency; facilitating positive experiences; taking as much time as needed; respecting and encouraging choice making; timeliness and frequency of dental appointments; communication between support workers, dental professionals and the person with mental retardation; problem solving; assisting the person with disability to learn skills; and desensitisation. Contributing factors in the physical, social, and organizational environment also were identified.

[Psychotherapeutic treatment of traumatic stress with the EMDR (Eye Movement Desensitization and Reprocessing) method]. / Traumatherapie mit der Fingerspitze. Die überraschenden Erfolge der EMDR-Methode.

EMDR (Eye Movement Desensitization and Reprocessing) is a method, developed at the end of the nineteen-eighties, for the treatment of the post-traumatic stress disorder (PTSD). The patient is asked to concentrate on certain aspect of the traumatic memory while keeping his eyes fixed on the movements of the therapist's finger. Apparently, this triggers information processing that results in appreciable relief for the patient. The method has proven to be equally as effective as behavioral-therapeutic techniques, and, has in the meantime, been included in national and international guidelines for the treatment of PTSD. The indications for EMDR treatment include not only PTSD, but, increasingly, also other, sometimes more severely chronic, it trauma sequelae. Within the framework of basic care, EMDR must be embedded within a treatment plan and should, where applicable, be combined with other methods.

Science and pseudoscience in the development of eye movement desensitization and reprocessing: implications for clinical psychology.

The enormous popularity recently achieved by Eye Movement Desensitization and Reprocessing (EMDR) as a treatment for anxiety disorders appears to have greatly outstripped the evidence for its efficacy from controlled research studies. The disparity raises disturbing questions concerning EMDR's aggressive commercial promotion and its rapid acceptance among practitioners. In this article, we: (1) summarize the evidence concerning EMDR's efficacy; (2) describe the dissemination and promotion of EMDR; (3) delineate the features of pseudoscience and explicate their relevance to EMDR; (4) describe the pseudoscientific marketing practices used to promote EMDR; (5) analyze factors contributing to the acceptance of EMDR by professional psychologists; and (6) discuss practical considerations for professional psychologists regarding the adoption of EMDR into professional practice. We argue that EMDR provides an excellent vehicle for illustrating the differences between scientific and pseudoscientific therapeutic techniques. Such distinctions are of critical importance for clinical psychologists who intend to base their practice on the best available research.

Autistic disorder: a review for the pediatric dentist.

Dental publications on autism have been sparse since the first comprehensive article geared for the dental profession. New findings on the etiology of autistic disorder (AD) have been discovered, suggesting that it is an organic disorder characterized by abnormalities in the brain, especially the cerebellum and limbic system. This article summarizes the latest medical findings on the etiology, diagnosis, and treatment approaches of AD, and reviews the dental literature since 1969. The main dental topics reviewed are: oral health status and dental needs of patients with AD, characteristics of patients with AD, and self-injurious behavior (SIB) in the context of AD. Clinical behavior-management issues such as pharmacological and communicative techniques and physical restraint and desensitization are described. The affect of the dental office's environment and appointment structure on a patient with AD are presented.

Functional assessment and treatment of sleeping problems with developmentally disabled children: six case studies.

Sleeping problems are common among developmentally disabled children of young age and they may have adverse effects on the well-being of both child and parents. In the present study, results from functional assessment with four children suggested that sleeping problems were reinforced by parental attention whilst an undiagnosed seizure disorder was associated with nighttime crying with one child. Conditioned anxiety resulted in problems in settling to sleep with a sixth child. Behavioral (i.e., extinction, desensitization) and pharmacological (i.e., anticonvulsant) treatment resulted in a substantial reduction in sleeping problems with all children. Follow-up data indicate that effects were maintained.

Assessment and treatment of social phobia.

Social phobia is an anxiety disorder characterized by heightened fear and avoidance of one or more social or performance situations, including public speaking, meeting new people, eating or writing in front of others, and attending social gatherings. People with social phobia are typically anxious about the possibility that others will evaluate them negatively and/or notice symptoms of their anxiety. Social phobia affects up to 13% of individuals at some time in their lives and is usually associated with at least moderate functional impairment. Research on the nature and treatment of social phobia has increased dramatically over the past decade. As with many of the anxiety disorders, sensitive assessment instruments and effective treatments now exist for people suffering from heightened social anxiety. Typical assessment strategies include clinical interviews, behavioural assessments, monitoring diaries, and self-report questionnaires. Treatments with demonstrated efficacy for social phobia include pharmacotherapy (for example, phenelzine, moclobemide, selective serotonin reuptake inhibitor [SSRI] medications) and cognitive behaviour therapy (CBT) (for example, cognitive restructuring, in vivo exposure, social skills training). Although preliminary comparative studies suggest that both approaches are about equally effective in the short term, each approach has advantages and disadvantages over the other. Trials examining combined psychological and pharmacological treatments are now under way, although no published data on the relative efficacy of combined treatments are currently available.

Effectiveness of computer-generated (virtual reality) graded exposure in the treatment of acrophobia.

OBJECTIVE: The authors' goal was to examine the efficacy of computer-generated (virtual reality) graded exposure in the treatment of acrophobia (fear of heights). METHOD: Twenty college students with acrophobia were randomly assigned to virtual reality graded exposure treatment (N = 12) or to a waiting-list comparison group (N = 8). Seventeen students completed the study. Sessions were conducted individually over 8 weeks. Outcome was assessed by using measures of anxiety, avoidance, attitudes, and distress associated with exposure to heights before and after treatment. RESULTS: Significant differences between the students who completed the virtual reality treatment (N = 10) and those on the waiting list (N = 7) were found on all measures. The treatment group was significantly improved after 8 weeks, but the comparison group was unchanged. CONCLUSIONS: The authors conclude that treatment with virtual reality graded exposure was successful in reducing fear of heights.

Eye movement desensitization and reprocessing in posttraumatic stress disorder: a pilot study using assessment measures.

Spectacular claims have been made regarding the efficacy of eye movement desensitization and reprocessing (EMDR) in the treatment of posttraumatic stress disorder (PTSD), but almost entirely on the basis of patients' reports and without objective criteria. This study reports on the treatment of eight patients with a diagnosis of PTSD who received EMDR treatment over four sessions. Assessment measures included two structured interviews, three self-report inventories, and the electromyogram (EMG). Assessments were conducted pre and posttreatment, and at 3-month follow-up. Despite some residual pathology at posttreatment and follow-up, significant improvements were obtained on all measures and across all PTSD symptom clusters. Compared with other treatments of PTSD, change was achieved in far fewer sessions.

Medication use and the assessment of agoraphobic avoidance.

Many anxiety disorder patients who present for behaviour therapy are already taking anxiolytic medications. The present study added a new subscale to the Mobility Inventory labelled 'Without Medication' to assess possible reliance on medication for coping with phobic situations. 121 Patients with panic-related disorders were administered the scale. The results supported the reliability and validity of the existing Mobility Inventory subscales in general and of the new subscale in particular. It appears to reliably assess a clinically important domain that is not measured in traditional self-report measures of phobic avoidance.

Assessment and management of pathological gambling.

This article describes a brief treatment--imaginal desensitization--which enables pathological gamblers to retain control of gambling, discusses its development and advances evidence from 2-9 years' follow-up of its efficacy.
