Utilization of empirically supported psychotherapy treatments for individuals with eating disorders: A survey of psychologists

Treating Asian American women with eating disorders: multicultural competency and empirically supported treatment

Disordered eating and body dissatisfaction are occurring among Asian American women, but the vast majority of treatment literature is based on White Western women. Empirically supported treatments are increasingly encouraged for eating disorders, but therapists find little guidance for implementing them in a culturally sensitive manner. This paper reviews eating problems in Asian American women and explores concepts important to cultural competency in therapy. Examples of how cultural adaptations could be made to an empirically supported treatment are illustrated in a case scenario using aspects of C. G. Fairburn's Enhanced Cognitive Behavioral Therapy for Eating Disorders (2008).

Interesting practitioners in training in empirically supported treatments: research reviews versus case studies

It has been repeatedly demonstrated that clinicians rely more on clinical judgment than on research findings. We hypothesized that psychologists in practice might be more open to adopting empirically supported treatments (ESTs) if outcome results were presented with a case study. Psychologists in private practice (N=742) were randomly assigned to receive a research review of data from randomized controlled trials of cognitive-behavioral treatment (CBT) and medication for bulimia, a case study of CBT for a fictional patient with bulimia, or both. Results indicated that the inclusion of case examples renders ESTs more compelling and interests clinicians in gaining training. Despite these participants' training in statistics, the inclusion of the statistical information had no influence on attitudes or training willingness beyond that of the anecdotal case information.

Psychotherapy approaches for adolescents with eating disorders

PURPOSE OF REVIEW

Adolescence is the most common period for the onset of eating disorders, and early intervention is critical. Primary care providers should feel equipped to discuss psychotherapy approaches for eating disorders with adolescents and their families and to provide appropriate referrals. The present review focuses on six prominent treatment modalities and the evidence supporting each approach.

RECENT FINDINGS

Although the majority of studies about psychotherapy approaches for eating disorders focus on adult women, there is a growing body of research on effective treatments for an adolescent population. Family-based treatment (the 'Maudsley method') and supportive psychotherapy appear to be promising approaches for anorexia in teens. Treatments for bulimia yield extremely high relapse rates, but cognitive-behavioral therapy and family-based treatment are favored modalities. Dialectical behavior therapy and interpersonal psychotherapy may also be applicable to adolescent bulimia and binge eating. Most psychotherapists draw upon a variety of these treatment approaches, depending upon the patient's unique presentation. Regardless of the modality used, some degree of family involvement is important in limiting dropout and improving outcomes.

SUMMARY

Adolescent health providers need to be aware of the psychotherapy approaches recommended for teens with eating disorders in order to effectively refer patients to and collaborate with mental health providers.

Influential psychotherapy figures, authors, and books: An Internet survey of over 2,000 psychotherapists

In a partial replication and extension of a survey conducted 25 years ago (Smith, 1982), over 2,400 North American psychotherapists completed a Web-based survey in which they identified prominent figures in the psychotherapy field who have most influenced their practice and the best psychotherapy books they had read in the past 3 years. There is a continued prominence to leaders of the field from 25 years ago but who are now deceased, notably the top-ranked Carl Rogers. Three books on the top-10 list represent empirically supported therapies (ESTs); two are treatment manuals for an EST, and one is a self-help book derived from an EST that has itself been shown to be efficacious bibliotherapy. Differences between psychologist and nonpsychologist therapists in the choice of influential figures, authors, and books are negligible. Implications are discussed in terms of the contemporary context into which therapeutic innovations are disseminated, as well as the conditions that may be necessary for successful dissemination.

Use of empirically supported interventions for psychopathology: can the participatory approach move us beyond the research-to-practice gap?

Dissemination, or distribution, of empirically supported interventions (ESIs) for psychopathology remains a significant challenge. This paper reviews the principles of community-partnership research (CPR) and explores why CPR might improve distribution of psychological ESIs. Benefits of CPR include building trust, pooling resources and knowledge, and better serving a community by directly involving its members in the design and implementation of research. In addition, after establishing a community's trust using CPR, researchers are likely to be better positioned to partner with communities in the further distribution of ESIs via community networks. This paper reviews the case of dissonance-based eating disorder prevention interventions to provide an example of how CPR can facilitate the adoption and distribution of an ESI by a community, in this case, sororities. CPR also presents a number of challenges, however, because it is time consuming and does not always align with funding mechanisms and research designs used in randomized controlled trials. Further, CPR does not necessarily solve the challenge of training providers, though it may help with problem solving. Ultimately, we suggest that the benefits of CPR far outweigh the challenges, and hope that more researchers will adopt these practices so that more individuals can benefit from empirically supported psychological interventions.

The cost effectiveness of cognitive behavioral therapy for bulimia nervosa delivered via telemedicine versus face-to-face

OBJECTIVE

A number of effective treatments for bulimia nervosa have been developed, but they are infrequently used, in part due to problems with dissemination. The goal of this study was to examine the cost effectiveness of telemedicine delivery of cognitive behavioral therapy for bulimia nervosa.

METHOD

A randomized controlled trial of face-to-face versus telemedicine cognitive behavioral therapy for bulimia nervosa. One hundred twenty eight women with DSM-IV bulimia nervosa or eating disorder, not otherwise specified subsyndromal variants of bulimia nervosa were randomized to 20 sessions of treatment over 16 weeks. A cost effectiveness analysis from a societal perspective was conducted.

RESULTS

The total cost per recovered (abstinent) subject was $9324.68 for face-to-face CBT, and $7300.40 for telemedicine CBT. The cost differential was accounted for largely by therapist travel costs. Sensitivity analyses examining therapy session costs, gasoline costs and telemedicine connection costs yielded fundamentally similar results.

DISCUSSION

In this study, CBT delivered face-to-face and via telemedicine were similarly effective, and telemedicine delivery cost substantially less. These findings underscore the potential applicability of telemedicine approaches to eating disorder treatment and psychiatric treatment in general.

Training in Cognitive Behavioral Therapy in Psychiatry Residency

In January 2001, Accreditation Council of Graduate Medical Education accredited general psychiatry training programs were charged with the requirement to train residents in cognitive-behavioral therapy (CBT) to a level of competence. Programs were given the responsibility to delineate standards for trainees, to determine measures of competence, and to provide remediation for deficiencies in performance. Effective education in CBT in general and child and adolescent psychiatry residency training can be more successful when educators understand the barriers to implementation of empirically supported therapies (ESTs). Robust training programs in CBT must take into account cultural barriers to psychotherapy training and the educational demands placed on residents in adult and child and adolescent psychiatry. Resources for training and evaluation materials are available to training directors and teachers.

Factors influencing the utilization of empirically supported treatments for eating disorders

This study expands upon previous research investigating the use of empirically supported treatments (ESTs) for eating disorders by surveying a large sample of clinicians who specialize in treating eating disorders. Surveys developed for this study were sent to 698 members of a large, professional, eating disorder organization who were listed as treatment providers on the organization's website. Despite clinicians reporting frequently using CBT techniques, most identified something other than CBT or IPT as their primary approach to treatment. In contrast with previous research, the majority had received prior training in the use of manual-based treatments. However, consistent with previous investigations, most denied regular use of such treatments. Although manual-based CBT and IPT are referred to as "treatments of choice," professional clinicians in the field are not consistently using them. Responses suggest several barriers to the utilization of ESTs in practice.

A content analysis of advertisements for psychotherapy workshops: implications for disseminating empirically supported treatments

This study involved a content analysis of 261 unique advertisements for psychotherapy workshops that appeared in two bimonthly clinical magazines, Psychotherapy Networker and Counselor, during a 2-year period. Two independent judges coded each advertisement and documented the type and prevalence of advertising appeals used. From the seminal diffusion of innovations model, Rogers' (2003) five perceived characteristics of innovations found to influence adoption in diverse fields were not well represented in these workshops appeals, appearing less than 10% each. Few advertisements cited specific empirically supported treatments or presented any evidence of treatment effectiveness beyond expert testimonials. The most frequently noted appeals were to benefit the clinician (e.g., earning education credit or developing skills), characteristics that enhance credibility of the workshop (e.g., reference to storied history or mention of faculty), and features of the advertisements itself (e.g., use of superlatives and exclamation points). Promotional strategies to advertise psychotherapy workshops can be used to inform the dissemination of empirically supported treatments.

A randomized trial comparing the efficacy of cognitive-behavioral therapy for bulimia nervosa delivered via telemedicine versus face-to-face

OBJECTIVE

A major problem in the delivery of mental health services is the lack of availability of empirically supported treatment, particularly in rural areas. To date no studies have evaluated the administration of an empirically supported manual-based psychotherapy for a psychiatric condition via telemedicine. The aim of this study was to compare the relative efficacy and acceptability of a manual-based cognitive-behavioral therapy (CBT) for bulimia nervosa (BN) delivered in person to a comparable therapy delivered via telemedicine.

METHOD

One hundred twenty-eight adults meeting DSM-IV criteria for BN or eating disorder-not otherwise specified with binge eating or purging at least once per week were recruited through referrals from clinicians and media advertisements in the targeted geographical areas. Participants were randomly assigned to receive 20 sessions of manual-based, CBT for BN over 16 weeks delivered either face-to-face (FTF-CBT) or via telemedicine (TV-CBT) by trained therapists. The primary outcome measures were binge eating and purging frequency as assessed by interview at the end of treatment, and again at 3- and 12-month follow-ups. Secondary outcome measures included other bulimic symptoms and changes in mood.

RESULTS

Retention in treatment was comparable for TV-CBT and FTF-CBT. Abstinence rates at end-of-treatment were generally slightly higher for FTF-CBT compared with TV-CBT, but differences were not statistically significant. FTF-CBT patients also experienced significantly greater reductions in eating disordered cognitions and interview-assessed depression. However, the differences overall were few in number and of marginal clinical significance.

CONCLUSIONS

CBT for BN delivered via telemedicine was both acceptable to participants and roughly equivalent in outcome to therapy delivered in person.

The quality of treatment of eating disorders: a comparison of the therapists' and the patients' perspective

OBJECTIVE

The aims of this study were to investigate the quality of treatment of eating disorders (EDs) from the therapists' and patients' perspective and to compare their views.

METHOD

The Questionnaire for Eating Problems and Treatment (QEPT) was administered to 73 therapists working with patients with ED, to 156 current ED and 148 former ED patients. The QEPT addresses the quality of treatment of EDs. ED diagnosis was assessed by the Eating Disorder Examination Questionnaire. Answers were analyzed quantitatively and qualitatively.

RESULTS

Both therapists and patients most often mentioned focus of treatment, therapeutic alliance, and communicational skills as important aspects of the quality of treatment. However, they valued similar topics differently. Therapists valued the focus on ED symptoms and behavioral change more highly, whereas patients underscored the importance of the therapeutic relationship and addressing underlying problems. Most therapists work from a cognitive behavioral orientation, but protocol-based treatment was not found important.

CONCLUSION

There is an avid need for dissemination of evidence-based treatment. Therapists' and patients' views supplement current evidence-based knowledge on treatment quality of EDs. Optimal treatment of EDs will be facilitated when these three bodies of knowledge-the available evidence and the therapists' and patients' views-are integrated.

I know what you did last summer (and it was not CBT): a factor analytic model of international psychotherapeutic practice in the eating disorders

OBJECTIVE

Although several studies have shown that eating disorders clinicians do not generally use treatment manuals, findings regarding what they do use have typically been vague, or closely linked to a particular theoretical approach. Our goal was to identify what eating disorder clinicians do with their patients in a more theoretically neutral context. We also sought to describe an empirically defined approach to psychotherapeutic practice as defined by clinicians via factor analysis.

METHOD

A survey developed for this study was administered to 265 clinicians recruited online and at regional and international meetings for eating disorders professionals.

RESULTS

Only 6% of respondents reported they adhered closely to treatment manuals and 98% of the respondents indicated they used both behavioral and dynamically informed interventions. Factor analysis of clinicians' use of 32 therapeutic strategies suggested seven dimensions: Psychodynamic Interventions, Coping Skills Training, Family History, CBT, Contracts, Therapist Disclosure, and Patient Feelings.

CONCLUSION

The findings of this study suggest that most clinicians use a wide array of eating disorder treatment interventions drawn from empirically supported treatments, such as CBT-BN, and from treatments that have no randomized controlled trial support. Factor analysis suggested theoretically linked dimensions of treatment, but also dimensions that are common across models.

Management of bulimia nervosa

Bulimia nervosa is a disorder of complex etiology that tends to occur in young women. These individuals binge eat and purge by vomiting or other means, and often have depression, anxiety, substance abuse and extremes of impulse control. It is thought that binge eating and purging behaviors are, at least in part, a means of coping with dysphoric mood states and interpersonal stress. Bulimic symptoms are not likely to abate without development of new coping skills and behaviors. In the past 25 years, considerable progress has been made in developing specific psychotherapies and medication for the treatment of bulimia nervosa. Despite this progress, many individuals have partial responses to therapy and may remain chronically ill. This complex illness often requires a multidisciplinary team of professionals for effective management and, despite significant advances in treatment, bulimia nervosa continues to present major challenges for providers of care.

Who is providing what type of psychotherapy to eating disorder clients? A survey

OBJECTIVE

Little is known about the psychotherapies delivered to eating-disordered clients by community therapists. We sought to describe the education and training of psychotherapists working with eating-disordered clients, the psychotherapeutic approaches used, and the reasons for use.

METHOD

Eligible Calgary clinicians were identified and asked to complete a 25-item telephone interview.

RESULTS

The response rate was 74%. Educational backgrounds and fields of specialization of clinicians who completed the survey (n = 52) varied widely, as did the psychotherapies used. The most common primary therapeutic orientations of respondents were eclectic therapy (50%), cognitive-behavioral therapy (CBT; 33%), and addiction-based therapy (6%). Most clinicians (87%) reported frequently using CBT techniques with eating-disordered clients. The reasons given for using primary therapeutic approaches varied by clinicians' preferred therapeutic approach and education level.

CONCLUSION

Clinicians generally choose to tailor treatment to individual needs rather than base decisions on the level of empirical support. These findings have implications for dissemination of empirically supported psychotherapies.

A naturalistic study of psychotherapy for bulimia nervosa, part 1: comorbidity and therapeutic outcome

Data from naturalistic samples provide an important complement to findings from randomized trials of psychotherapy. A random national sample of US clinicians provided data on 145 completed treatments of patients with bulimic symptoms. Treatment in the community was substantially longer than treatment prescribed in manuals, with a mean length of cognitive-behavioral therapy of 69 sessions and significantly longer for eclectic and psychodynamic therapies. Most patients treated in the community had substantial comorbidity, and this comorbidity was associated with longer treatments and poorer outcome. Using four common exclusion criteria from randomized controlled trials for bulimia nervosa, approximately 40% of the naturalistic sample would have been excluded from randomized controlled trials. These patients showed higher pretreatment severity and required longer treatments to achieve positive outcomes relative to patients who did not meet these exclusion criteria.

Psychological Treatment of Eating Disorders

Manual-based cognitive behavior therapy (CBT) is presently the most effective treatment of bulimia nervosa. Its efficacy is limited, however. Different strategies for improving upon current manual-based CBT are discussed, including combining CBT with antidepressant medication, integrating CBT with alternative psychological therapies, and expanding the scope and flexibility of manual-based CBT. CBT is underutilized in clinical practice. Dissemination of evidence-based treatment is a priority. Research on anorexia nervosa is minimal. Effective treatments have yet to be developed, although the Maudsley method of family therapy has shown the most promise in the treatment of adolescents. The most commonly seen eating disorders in clinical practice are those classified as "eating disorder not otherwise specified." With the exception of binge eating disorder (BED), however, they have been neglected by researchers. Several psychological therapies have been shown to be effective in treating BED. Controversy exists over whether treatment-specific effects have been identified. Whereas treatments have proved effective in eliminating binge eating and associated eating disorder psychopathology, achieving clinically significant weight loss remains a challenge.

Eating disorders guidelines from NICE

CONTEXT

January, 2004, marked the publication of NICE guidelines for the treatment of eating disorders, a series of recommendations from a multidisciplinary, comprehensive, and rigorous process. The recommendations are assigned a grade from A (strong empirical support from well-conducted randomised trials) to C (expert opinion without strong empirical data). Over 100 recommendations were made, most of which were given a C grade. No specific recommendations were made for anorexia nervosa. Cognitive behavioural therapy for bulimia nervosa was assigned grade A because of the evidence showing that it is superior to other psychological and drug treatments. Antidepressants for bulimia nervosa were given grade B. No specific recommendations were made for atypical eating disorders except for binge-eating disorder (cognitive behavioural therapy was recommended [A]).

STARTING POINT

The methodological rigour of the NICE guidelines is in contrast with the current Practice Guideline for Eating Disorders (PGED) of the American Psychiatric Association. PGED does not detail criteria for evaluating supporting research. Instead of making clear recommendations, PGED is uncritically inclusive and emphasises subjective judgment of individual clinicians. The NICE guidelines balance recommending specific treatments against the importance of clinical judgment when guideline recommendations are not readily applicable.

WHERE NEXT

Evidence-based guidelines are limited by the quality of the available research and its clinical relevance. The NICE guidelines underscore the absence of sufficient evidence for guidance in several important areas, such as atypical eating disorders (eating disorders not otherwise specified) which are the most common. Research on the treatment of these atypical eating disorders is needed. Evidence-based psychological treatments are not routinely implemented in general practice. Dissemination of these demonstrably effective treatments poses a challenge, and learning how to implement evidence-based psychological treatments and monitor their use is a research priority.

A survey of psychologists’ attitudes towards and utilization of exposure therapy for PTSD

Although research supports the efficacy of exposure therapy for PTSD, some evidence suggests that exposure is under-utilized in general clinical practice. The purpose of this study was to assess licensed psychologists' use of imaginal exposure for PTSD and to investigate perceived barriers to its implementation. A total of 852 psychologists from three states were randomly selected and surveyed. An additional 50 members of a trauma special interest group of a national behavior therapy organization were also surveyed. The main survey results indicate that a large majority of licensed doctoral level psychologists do not report use of exposure therapy to treat patients with PTSD. Although approximately half of the main study sample reported that they were at least somewhat familiar with exposure for PTSD, only a small minority used it to treat PTSD in their clinical practice. Even among psychologists with strong interest and training in behavioral treatment for PTSD, exposure therapy is not completely accepted or widely used. Clinicians also appear to perceive a significant number of barriers to implementing exposure.

Survey of regional health care providers on selection of treatment for bulimia nervosa

OBJECTIVE

To determine which treatments clinicians currently recommend for patients with bulimia nervosa (BN), to find out if they recommended evidence-based treatments, and to assess availability and clinician satisfaction with treatment options.

METHODS

Surveys were sent to 1,263 health care providers in Minnesota, Iowa, and Wisconsin who were likely to encounter patients with BN. These health care providers comprised all primary care clinicians, physician assistants, advanced practice nurses, and all mental health/chemical dependency clinicians (MDs, Clinical Nurse Specialist (CNS), social workers, doctoral and masters-level therapists, and chemical dependency (CD) counselors) affiliated with the Mayo Clinic in Rochester, Minnesota.

RESULTS

Evidence-based treatments for BN are recommended consistently and are generally perceived to be available, at least to practitioners affiliated with a large medical center in the Midwest. Clinician satisfaction with treatment options is modest.

DISCUSSION

Clinicians are recommending evidence-based treatments for BN patients and find them to be generally available. Modest satisfaction with available treatments may reflect a realistic understanding of treatment options, which need further development.

Comparing clinical and research treatments for eating disorders

OBJECTIVE

This study evaluated whether there is a gap between research and practice in the treatment of eating disorders.

METHOD

Psychologists in clinical practice (N = 126) were surveyed regarding their treatment of a recent client with an eating disorder and a content analysis of published treatment outcome studies for eating disorders (N = 76) was conducted.

RESULTS

The treatment of eating disorders in clinical and research settings was found to differ significantly on several variables, including the types of therapeutic issues addressed and the frequency of comorbidity seen in clients. Logistic regression analyses found that the frequency with which psychologists read journal articles about eating disorders was significantly related to whether their clients received empirically validated treatment.

DISCUSSION

Psychologists in clinical practice are not using empirically validated treatments not only because of a lack of training but also because such treatments provide little guidance for dealing with the issues and comorbid problems that their clients with eating disorders often have.

Investigational drugs for eating disorders

The eating disorders anorexia nervosa, bulimia nervosa and binge eating disorder are common, significant public health problems which are treated with nutritional, psychotherapeutic and pharmacological interventions. A number of drugs (mostly antidepressant drugs) are currently used in their treatment to some benefit, but there is substantial room for improvement. A wide variety of compounds are listed as under investigation for the treatment of eating disorders. They have a diverse variety of mechanisms of action, reflecting the complex nature of the control of food intake. While none of these compounds are close to release at present, the diversity of mechanisms under study lend some optimism that more effective approaches will be identified.

Eating disorders

Eating disorders are an important cause of physical and psychosocial morbidity in adolescent girls and young adult women. They are much less frequent in men. Eating disorders are divided into three diagnostic categories: anorexia nervosa, bulimia nervosa, and the atypical eating disorders. However, the disorders have many features in common and patients frequently move between them, so for the purposes of this Seminar we have adopted a transdiagnostic perspective. The cause of eating disorders is complex and badly understood. There is a genetic predisposition, and certain specific environmental risk factors have been implicated. Research into treatment has focused on bulimia nervosa, and evidence-based management of this disorder is possible. A specific form of cognitive behaviour therapy is the most effective treatment, although few patients seem to receive it in practice. Treatment of anorexia nervosa and atypical eating disorders has received remarkably little research attention.

Administering cognitive-behavioral therapy for bulimia nervosa via telemedicine in rural settings

OBJECTIVE

This report describes the therapy of 2 women with bulimia nervosa who were treated using cognitive-behavioral therapy delivered via telemedicine.

METHOD

The telecommunication link was established using a 128-Kbps ISDN switchable data line.

RESULTS

Both cases were treated successfully and were doing well at 1-month follow-up.

DISCUSSION

These cases illustrate that this methodology may make it possible to deliver manual-based psychotherapies to patients with eating disorders in remote areas.

Towards effective treatment of eating disorders: nothing is as practical as a good theory

There is much room for improvement in the treatment of eating disorders, anorexia nervosa in particular. It is argued that for more effective treatment a radical change in thinking and doing is needed. First, the wide-spread multicausal model of eating disorders must be abandoned and replaced by (a) fundamental strategic research into the most parsimonious explanation of eating disorders and (b) interventions solely directed on the specific maintaining mechanisms. Second, evidence-based working is needed in mental health care. In daily practice, two of three psychotherapists do not treat their eating disordered patients with the best treatment available, i.e. cognitive behaviour therapy. The Dutch Ministry of Health, Welfare and Sport tried to improve the care for eating disorder patients by the nomination of several specialist hospital units. These units are, however, not selected for their treatment quality or the use of evidence-based treatment protocols. It is argued that this ministerial operation will not increase the supply of effective treatment. The Minister obviously should have done two other things to improve the amount and quality of treatment supply for eating disorders: First, she better could invest in a broad array of workshops, training and supervision programs in cognitive behaviour therapy for all psychotherapists working with eating disorders. Second, since nothing is so practical as a good theory, the facilitation of research into parsimonious models of the relevant mechanisms as well as the experimental tests of interventions on these mechanisms would have been a promising move to effective treatment.

Combining pharmacotherapy and psychotherapy in the treatment of patients with eating disorders

The available treatment literature supports a role for medication management in the treatment of both AN and BN. The data on BN are clearer and suggest that antidepressant therapy--fluoxetine being the drug most widely studied--is superior to treatment with placebo but less effective than CBT alone, with one such study suggesting that the combination may provide optimal treatment. Specific recommendations as to when to add or not add antidepressants to CBT have been made, although the rules suggested here have yet to be empirically tested. Although the data on AN are much more limited, information available suggests a lack of efficacy for SSRIs in patients with AN at low weight and considerable use for SSRIs when used in combination with psychotherapy for patients with AN following weight recovery. Where do we go from here? Several pressing issues require careful study. First, in the case of patients with AN, can other agents, in particular the new atypical antipsychotics, be useful in treating patients when they are at low weight? In terms of relapse prevention, can the available findings indicating a role for antidepressants in relapse prevention be replicated, and, if so, can predictor variables that are associated with antidepressant response be identified? In the case of BN, clinicians need to know more about the best possible way to sequence interventions. It has been proposed to add medication to CBT early in treatment if the response to CBT alone is thought to be inadequate. However, other models should be considered, such as stepped-care models in which self-help manuals are used in conjunction with medications. The advantage of these interventions is they could be made more widely available than CBT, which requires a specialist's care. Also, several other new agents, such as sibutramine, which is a drug with serotonin and norepinephrine reuptake inhibition effects, should be tested empirically in subjects with BN, given their pharmacologic profiles.
