The shifting perspectives study protocol: Cognitive remediation therapy as an adjunctive treatment to family based treatment for adolescents with anorexia nervosa.

ABSTRACT:

Background

Adolescents with anorexia nervosa have set-shifting inefficiencies that can be exacerbated by starvation and that may interfere with outcomes of treatment interventions. Cognitive Remediation Therapy (CRT), an adjunctive treatment focused on improving set-shifting, can target inefficiencies and may augment treatment effectiveness. The best way to add CRT to the standard of care (Family Based Treatment, FBT) for adolescents with anorexia remains understudied.

Methods/design

This is a randomized controlled trial designed to determine if CRT is effective in increasing flexibility in adolescents with anorexia and/or their parents. Participants are adolescents 12-18 years old with anorexia and their parents. 54 family groups will be randomized into one of three groups: FBT only, FBT plus Parent-focused CRT, or FBT plus Adolescent-focused CRT. Psychosocial, neurocognitive, and behavioral measures will be collected throughout the study.

Discussion

This is the first study of its kind to apply CRT to parents. All forms of CRT in the context of anorexia have targeted the individual with anorexia's thinking style. We propose that it may be impactful to target the parent of the adolescent with anorexia as parents carry the burden of treatment and re-nourishment of their child during FBT and may have similar thinking styles.

Conclusion

This study takes an experimental therapeutics approach to further our understanding of the mechanisms of treatment for adolescents with anorexia. It focuses on increasing cognitive flexibility in patients or their parents and determining the appropriate dose of CRT needed to achieve positive change.

Project description:UnlabelledResearch on treatments in anorexia nervosa (AN) is scarce. Although most of the therapeutic programs used in 'real world practice' in AN treatment resort to multidisciplinary approaches, they have rarely been evaluated.ObjectiveTo compare two multidimensional post-hospitalization outpatients treatment programs for adolescents with severe AN: Treatment as Usual (TAU) versus this treatment plus family therapy (TAU+FT).MethodSixty female AN adolescents, aged 13 to 19 years, were included in a randomized parallel controlled trial conducted from 1999 to 2002 for the recruitment, and until 2004 for the 18 months follow-up. Allocation to one of the two treatment groups (30 in each arm) was randomised. The TAU program included sessions for the patient alone as well as sessions with a psychiatrist for the patient and her parents. The TAU+FT program was identical to the usual one but also included family therapy sessions targeting intra-familial dynamics, but not eating disorder symptoms. The main Outcome Measure was the Morgan and Russell outcome category (Good or Intermediate versus Poor outcome). Secondary outcome indicators included AN symptoms or their consequences (eating symptoms, body mass index, amenorrhea, number of hospitalizations in the course of follow-up, social adjustment). The evaluators, but not participants, were blind to randomization.ResultsAt 18 months follow-up, we found a significant group effect for the Morgan and Russell outcome category in favor of the program with family therapy (Intention-to-treat: TAU+FT :12/30 (40%); TAU : 5/29 (17.2%) p?=?0.05; Per Protocol analysis: respectively 12/26 (46.2%); 4/27 (14.8%), p?=?0.01). Similar group effects were observed in terms of achievement of a healthy weight (i.e., BMI?10(th) percentile) and menstrual status.ConclusionsAdding family therapy sessions, focusing on intra-familial dynamics rather than eating symptomatology, to a multidimensional program improves treatment effectiveness in girls with severe AN.Trial registrationControlled-trials.com ISRCTN71142875.

Project description:BackgroundPatients with anorexia nervosa (AN) experience difficulties in neurocognitive functioning in the acute phase of illness which might be related to clinical presentation, but also in the apparently remitted state after weight recovery. Among the most commonly reported persistent deficits is cognitive inflexibility, which can be interpreted as a vulnerability trait or a "neuropsychological scar" reflecting the detrimental effect of prolonged semi-starvation in patients with a long duration of illness. Studies of adolescent samples with a relatively short clinical course may enable avoiding the effect of prolonged illness and help to determine whether neuropsychological deficits are trait or state dependent. The aim of this study is to assess cognitive functioning in adolescents with AN before and after the inpatient treatment programme, including cognitive remediation therapy (CRT).MethodsForty-seven adolescent female inpatients with AN diagnosed according to DSM-5 and fifty healthy female adolescents matched for the education level and age were recruited. The patients underwent a multimodal treatment including a ten-week CRT. The standardized and cross-validated neuropsychological (Trail Making Test - TMT A and B, Color-Word Stroop Task - CWST, Ruff Figural Fluency Test - RFFT) and clinical measurements (Beck Depression Inventory - BDI, Eating Attitude Test - EAT-26, Yale-Brown Obsessive Compulsive Scale - Y-BOCS) were used to assess both clinical (in the acute phase and after partial weight recovery) and control subjects.ResultsInitially, AN patients performed significantly worse compared to the controls, but afterwards, inpatient treatment improvement was noted on all examined measures. In a few subtests (TMT, CWST) performance of AN patients after the programme was still significantly poorer than in HC.ConclusionsCognitive inflexibility in adolescent AN patients, as measured with TMT, CWST, and RFFT tends to improve after therapy. Nevertheless, a few neuropsychological subtests which did not show complete normalization may warrant attention in subsequent studies. Further research including control intervention is needed to conclude whether CRT intervention affects the outcome.

Project description:Anorexia nervosa (AN) is a complex psychiatric disorder with high morbidity and mortality rates. While many individuals make full recoveries, up to a third of patients develop a chronic, treatment-resistant form of the illness that leads to a premature death in 15-20% of those affected. There have been few advances in treatment, both in terms of psychological or pharmacologic treatment over the last 30 years. Food aversion is commonly cited by patients with AN as a barrier to normalizing eating and weight. Our group has a keen interest in examining factors that might allow this to be addressed, thus improving treatment outcomes through personalized dietary plans or nutritional supplementation related to underlying genetic status. We demonstrated that polyunsaturated fatty acids (PUFAs)-derived bioactive lipids (eicosanoids) are implicated in not only the risk of AN, but also with its comorbid psychopathology. Of interest, the differential postprandial omega 6-derived eicosanoid shift observed in AN highlights the possibility that the metabolism of PUFAs is an important mechanism underlying the profound food version, contributing to pathological food restriction in AN. A concise knowledge of the relationships among PUFAs, eicosanoids, and AN clinical course and psychopathology could be the key to developing personalized nutritional rehabilitative treatments for those suffering from AN. This paper provides a comprehensive overview of the literature on PUFAs in AN. We also selectively reviewed the clinical benefits PUFA treatments exert in other psychiatric diseases, on weight and appetite regulation, and for resolution of inflammation, all of which are relevant in the disease course and outcome of AN. We propose that personalized PUFA formulation be developed and tested as a novel adjunctive treatment for patients with AN. We hypothesize that with personalized PUFA formulation, food aversion and anxiety about eating will decrease while mood, dietary behavior, and weight restoration will improve in AN, leading to improvements in the overall treatment outcome.

Project description:BackgroundAnorexia nervosa (AN) can significantly affect cognitive well-being. Cognitive remediation therapy (CRT) is regarded as one of the effective treatments for cognitive impairment in some mental illnesses such as schizophrenia, bipolar disorder, and attention deficit. For this reason, this systematic review and meta-analysis aim to assess the effectiveness of CRT in patients with AN.MethodsWe conducted a search of Medline, ClinicalTrials.gov, and the Cochrane Database of Systematic Reviews from the inception of each database through April 8, 2023. Randomized clinical trials evaluating the effectiveness of CRT in comparison to placebo or other psychological treatments in patients with AN were included. The quality of the studies was assessed using the revised Cochrane risk-of-bias tool. For meta-analysis, effect sizes were measured using mean difference (MD) utilizing the random-effects model and inverse variance (IV) technique. To evaluate the certainty of the evidence, we applied the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) criteria. The study was registered in PROSPERO, ID: CRD42023411784.ResultsIn the systematic review, six studies were included, of which four underwent meta-analysis. Among these, three trials encompassing 413 participants showed that CRT was associated with improved cognitive flexibility compared to control at the end of treatment (MD = -0.21, 95% CI [-0.44, 0.02], P=0.81, I2 = 0%). In two trials with 143 patients, those who received CRT showed similar effects on the severity of AN symptoms compared to the control group in the self-reporting questionnaires: EDE-Q (MD = -0.25, 95% CI [-0.76, 0.27], P=0.77, I2 = 0%) and EDEQOL (MD = -0.19, 95% CI [-0.41, 0.03], P=0.84, I2 = 0%).ConclusionCRT did not show a statistically significant difference compared to the control group in improving abstract thinking skills and quality of life in individuals with AN. That indicates that CRT's efficacy remains inconclusive. Further research with larger, more diverse samples is needed to determine its long-term effects and potential benefits.Systematic review registrationPROSPERO, identifier CRD42023411784.
