Abstract
The token economy is a well-established and widely used behavioral intervention. A token economy is comprised of six procedural components: the target response(s), a token that functions as a conditioned reinforcer, backup reinforcers, and three interconnected schedules of reinforcement. Despite decades of applied research, the extent to which the procedures of a token economy are described in complete and replicable detail has not been evaluated. Given the inherent complexity of a token economy, an analysis of the procedural descriptions may benefit future token economy research and practice. Articles published between 2000 and 2015 that included implementation of a token economy within an applied setting were identified and reviewed with a focus on evaluating the thoroughness of procedural descriptions. The results show that token economy components are regularly omitted or described in vague terms. Of the articles included in this analysis, only 19% (18 of 96 articles reviewed) included replicable and complete descriptions of all primary components. Missing or vague component descriptions could negatively affect future research or applied practice. Recommendations are provided to improve component descriptions.

Hart S, Franklin RC, Russell J, Abraham S. A review of feeding methods used in the treatment of anorexia nervosa. J Eat Disord 2013; 1:36. [PMID: 24999415 PMCID: PMC4081821 DOI: 10.1186/2050-2974-1-36] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/15/2012] [Accepted: 07/26/2013] [Indexed: 03/07/2023] Open
Abstract
BACKGROUND Clear evidence based guidelines on the best and safest method of achieving and maintaining normal body weight during inpatient treatment of Anorexia Nervosa (AN) are currently not available. Oral feeding with food alone, high-energy liquid supplements, nasogastric feeding and parenteral nutrition all have the potential to achieve weight gain in the treatment of AN but the advantages and disadvantages of each method have not been comprehensively evaluated. A literature search was undertaken to identify papers describing feeding methods used during inpatient treatment of AN. The selection criteria searched for papers that described the feeding method; and reported weight change variables such as admission and discharge weight in kilograms, or Body Mass Index; or weight change over the course of inpatient treatment. RESULTS Twenty-six papers were identified, describing a total of 37 samples with a mean sample size of 58.9 participants, and a range from 6 to 318. The majority (84.6%) of papers were observational cohorts and retrospective chart reviews. The most common feeding method described was nasogastric feeding and food, then high-energy liquid supplements and food. CONCLUSIONS There is limited evidence on the efficacy of feeding methods used in the refeeding and nutritional rehabilitation of AN, therefore no conclusion can be made about the most effective method of achieving weight gain during inpatient treatment. While there are a number of papers exploring this issue there is no consistency in the way the information is reported to enable comparisons between the different methods. There is an urgent need for research in this area to guide decision-making in the inpatient management, refeeding and nutritional rehabilitation of AN.

Abstract
BACKGROUND For the German treatment guidelines for eating disorders, the literature on psychological treatment of anorexia nervosa (AN) was reviewed systematically. As a common meta-analysis of randomized clinical trials proved to be impossible, a review of all available clinical trials was conducted, statistically integrating standardized mean change scores. Research questions comprised differential effects of therapeutic techniques and settings as well as determining which weight gains could be expected. METHODS After an extensive literature search, studies were selected, rated by 3 independent raters. Weight gain as the main outcome criterion was transformed into standardized mean change scores. Effect sizes were checked for homogeneity. RESULTS 57 studies containing 84 treatment arms and 2,273 patients could be integrated. Studies differed considerably in quality. The strongest bias identified was reporting selectively on completers or failures, versus intention-to-treat samples. No significant differences between effect sizes could be identified concerning treatment setting, technique or patient characteristics. If treatment time is taken into account, inpatient treatment produced a faster weight gain than outpatient treatment. CONCLUSION The study describes weight gains which can be reached in outpatient and inpatient settings. It yielded no salient results speaking for a certain therapy technique, setting or procedure. Treatment guidelines for psychological treatment of AN still have to rely on lower level evidence.

Abstract
AIM To describe patterns of weight change in patients admitted to a specialised eating disorder program with established protocols for inpatient refeeding. METHODS Weight records between January 2000 and December 2006 were categorised using Body Mass Index (BMI) at first admission (BMI ranges < 14.0, 14.1-17.49, 17.5-18.9 kg/m(2)). Total weight gained, number of days of inpatient treatment and rate of weekly weight gain were examined. RESULTS In total there were 247 patients representing 414 admissions. The rate of weight gain was 0.77, 0.63 and 0.53 kg/week, respectively, for each BMI group. Twenty patients (8.1%) in the refeeding program did not gain weight. CONCLUSION Weight gain in underweight patients is highly variable. A greater understanding of the processes that contribute to weight gain, and establishment of best practice in achieving weight gain in patients needs to be determined. This data provide detailed information about expectations for refeeding without artificial feeding.

Abstract
Eating disorders are challenging and difficult to treat, because of the necessity of a multidisciplinary treatment team for effective outcomes and the high mortality rate of anorexia nervosa. An adequate initial assessment and evaluation requires a psychiatric assessment, a medical history and medical examination, a social history and an interview of family members or collateral informants. A comprehensive eating disorder treatment team includes a psychiatrist coordinating the treatment and appropriate medical physician specialists, nutritionists, and psychotherapists. An adequate outpatient eating disorder clinic needs to provide individual psychotherapy with cognitive behavioral techniques specific for anorexia nervosa and bulimia nervosa, family therapy, pharmacological treatment and the resources to obtain appropriate laboratory tests. Eating disorder patients requiring inpatient care are best treated in a specialized eating disorder inpatient unit. A cognitive behavioral framework is most useful for the overall unit milieu. Medical management and nutritional rehabilitation are the primary goals for inpatient treatment. Various group therapies can cover common core eating disorder psychopathology problems and dialectical behavior therapy groups can be useful for managing emotional dysregulation. Residential, partial hospitalization and day treatment programs are useful for transitioning patients from an inpatient program or for patients needing some monitoring. In these programs, at least one structured meal is advisable as well as nutritional counseling, group therapy or individual counseling sessions. Group therapies usually address issues such as social skills training, social anxiety, body image distortion or maturity fears. Unfortunately there is s paucity of evidence based randomized control trials to recommend the salient components for a comprehensive service for eating disorders. Experienced eating disorder clinicians have come to the conclusion that a multidisciplinary team approach provides the most effective treatment.

Abstract
Eating disorders represent a significant source of psychological impairment among adolescents. However, most controlled treatment studies have focused on adult populations. This review provides a synthesis of existing data concerning the efficacy of various psychosocial interventions for eating disorders in adolescent samples. Modes of therapy examined in adolescent samples include family therapy, cognitive therapy, behavioral therapy, and cognitive behavioral therapy mostly in patients with anorexia nervosa. At this time, the evidence base is strongest for the Maudsley model of family therapy for anorexia nervosa. Evidence of efficacy for other treatments and other conditions is limited by several methodological factors including the small number of studies, failure to use appropriate control conditions or randomization procedures, and small sample sizes (i.e., fewer than 10 participants per treatment arm). Potential moderators and mediators of treatment effect are reviewed. Finally, results from adolescent studies are contrasted with those from adult studies of eating disorders treatment. Many studies of adult populations comprise late adolescent/young adult participants, suggesting that findings regarding the efficacy of cognitive behavioral therapy for bulimia nervosa in adults likely extend to older adolescent populations.

Abstract
BACKGROUND An abnormality in regional cerebral blood flow (rCBF) in anorexia nervosa (AN) patients has been reported. There are very few studies that have investigated the rCBF changes in the recovery process of AN. METHODS For eight female AN patients, we performed (123)I-IMP single photon emission computed tomography (SPECT) and four psychological assessments (Eating Disorder Inventory (EDI), Eating Attitude Test (EAT), Self-Rating Depression Scale (SDS) and State-Trait Anxiety Inventory (STAI)) both before and after inpatient-behavioral therapy. SPECT images were analyzed using statistical parametric mapping software. We also performed correlational analysis between rCBF and clinical variables. RESULTS Following treatment, the patients showed significant body weight recovery. They showed significant improvement in EAT, SDS, STAI and a subscale of EDI - interoceptive awareness (IA) - but not in total EDI or other EDI subscales. Significant rCBF increases were observed in the precuneus, posterior cingulate cortex (PCC), right dorsolateral prefrontal cortex (DLPFC), anterior cingulate cortex (ACC) and medial prefrontal cortex (MPFC) by the treatment. Significant correlation was observed between rCBF of right DLPFC and IA score before treatment. CONCLUSIONS Changes of rCBF in right DLPFC, ACC, MPFC, PCC and precuneus were related to the AN recovery process and might be associated with improvement of IA following treatment.

Abstract
BACKGROUND The chance that an anorexia nervosa patient will be hospitalized depends more on circumstantial rather than on scientifically based factors. Although there is a lot of information on the treatment of anorexia nervosa patients in a residential setting, answers to questions relating to the "when," "where," and "how" of treatment are subjective. There is no clinical consensus and the paucity of controlled research is hampering the development of an evidence-based practice. RESULTS Increasing economic restraints through managed care policies limit the length of inpatient treatment, which leads to early discharge at a lower body weight, which leads to a higher likelihood of readmissions, which leads to increasing costs. DISCUSSION We will highlight important issues in the ongoing debate between economic demands and clinical challenges. Our goal is to stimulate critical reflections and systematic research.
