Acceptability and feasibility of self-help Cognitive Remediation Therapy for anorexia nervosa delivered in collaboration with carers: a qualitative preliminary evaluation study

Cognitive remediation therapy for patients with eating disorders: a qualitative study

BACKGROUND

Transdiagnostic Cognitive Remediation Therapy (TCRT) is a new adaptation of cognitive remediation therapy for eating disorders (EDs) developed to address common cognitive difficulties across ED diagnoses (i.e., cognitive flexibility, central coherence, and impulsivity). This is the first evaluation of this novel treatment. The aim of this study was to explore acceptability and patients' experience of TCRT.

METHODS

Thirteen patients diagnosed with restrictive or binge/purge subtypes of EDs and concurrent cognitive difficulties completed semi-structured qualitative interviews after receiving TCRT. Interview transcripts were analyzed using reflexive thematic analysis.

RESULTS

The analysis resulted in four main themes: (1) Treatment fit (2), Treatment experience (3), Perceived outcomes, and (4) Future recommendations. Eleven of the thirteen patients evaluated the treatment positively, found the focus relevant and expressed how it contributed to new insights related to thinking style. Seven of the patients also described it as a starting point for making changes and using new strategies. Importantly, experiencing some challenges related to the cognitive difficulties addressed in the treatment seemed essential for engagement.

CONCLUSION

Offering TCRT as an adjunctive treatment for patients with EDs and concurrent cognitive difficulties can be a way to engage patients in treatment, build therapeutic alliances and provide important awareness and strategies to handle challenges related to thinking style.

TRIAL REGISTRATION

This study is part of a larger randomized controlled trial, ClinicalTrials.gov Id: NCT03808467.

Young people and parents' views towards individual cognitive remediation therapy-qualitative findings from a feasibility randomised controlled trial

PURPOSE

Cognitive Remediation Therapy (CRT) has been used mostly in adults. Randomised Controlled Trials (RCTs) in anorexia nervosa (AN) have shown that CRT enhances cognitive flexibility, abstract thinking and is associated with quality-of-life improvement. More research is needed in younger populations.

METHODS

A single-centre feasibility RCT with young people (YP) with AN was conducted in an inpatient setting. A secondary aim of this study was to explore patient satisfaction and parents' views towards CRT to inform further development and implementation of CRT in YP. YP were asked to complete a therapy feedback questionnaire and write a letter with their views on CRT. Parents were asked to complete a questionnaire exploring their perceptions of CRT. Data were analysed using inductive thematic and deductive content analysis.

RESULTS

Both YP and parents valued CRT. Its engaging and pragmatic nature and its focus on thinking styles were perceived as a novel aspect. Parents expressed the need to be involved in the sessions to be able to continue to support their children at home.

CONCLUSIONS

This study confirms previous qualitative findings. Should a fully powered RCT be conducted, it would be important to take into account these findings to further adapt the content of the CRT sessions to the YP needs and to consider their parents' involvement in the sessions, which could also increase the likelihood of parents' engagement in providing their feedback.

LEVEL OF EVIDENCE

Level I: Evidence obtained from one randomized controlled trial.

Neuropsychological and clinical findings of Cognitive Remediation Therapy feasibility randomised controlled trial in young people with anorexia nervosa

OBJECTIVE

Randomised controlled trial (RCT) in adults with anorexia nervosa (AN) showed that Cognitive Remediation Therapy (CRT) enhances cognitive flexibility, abstract thinking and quality-of-life. Despite inconsistent findings, CRT has the potential as an adjunct treatment for young people (YP) with AN. A feasibility RCT was conducted in an inpatient setting. The study will also consider the effect of CRT in YP with AN and autistic symptoms.

METHODS

Participants were randomly allocated to the Immediate or Delayed condition to receive individual CRT sessions, in addition to standard treatment. A repeated measures design was conducted.

RESULTS

Eighty participants were recruited. The neuropsychological measures were feasible for evaluating individual CRT in YP. Significant improvements in set-shifting and central coherence were found, with no main effect between immediate and delayed condition. Significant interactions were found between the condition, and autism spectrum condition (ASC) and No-ASC subgroup, with significant positive impact of CRT on set-shifting in the No-ASC subgroup. There was some evidence that for the No-ASC subgroup, CRT was more effective if delivered at the start of the treatment; and for the ASC subgroup, that CRT was more effective if delivered at the later stage of treatment.

CONCLUSIONS

These findings suggest that the overall positive effect of CRT in set-shifting and central coherence alongside standard treatment. They also indicate the importance of screening for the presence of ASC which could require tailored CRT.

Critical incidents in anorexia nervosa: perspectives of those with a lived experience

BACKGROUND

Although social-emotional difficulties are believed play a key role in anorexia nervosa (AN), there is uncertainty regarding what these difficulties might look like. Previous research has largely focused on a "disease model" of social-emotional processing in AN with little attention paid to positive emotions and experiences. Therefore, the aim of the present study was to obtain a fuller picture of critical life events as identified by those with lived AN experience.

METHODS

Thirty-four participants aged 16-48 with current or past AN completed an online survey describing self-defined positive and difficult critical events. Thematic analysis was used to assess patterns in participants narrative responses.

RESULTS

Two major themes were identified in the descriptions of positive critical events: Moments of celebration and Unexpected positive outcomes. These major themes revealed increased external focus and some corrective experiences that challenged the participants pre-existing expectations leading to new positive outcomes. Difficult events clustered into life events that were identified as Eating disorder (ED) related and Non-ED related and included the dimensions of relational conflict and feeling unsupported.

DISCUSSION

The findings suggest that although negative emotionality was identified in the accounts of those with lived experience of AN capacity for "big-picture" thinking with and explicit focus on others was also identified. Moreover, an openness to corrective experiences that worked to challenge negative expectations was evident for some participants. Together these findings have scope as targets for further clinical research and treatment interventions.

The COVID-19 pandemic and eating disorders in children, adolescents, and emerging adults: virtual care recommendations from the Canadian consensus panel during COVID-19 and beyond

OBJECTIVE

The COVID-19 pandemic has had detrimental effects on mental health. Literature on the impact on individuals with eating disorders is slowly emerging. While outpatient eating disorder services in Canada have attempted to transition to virtual care, guidelines related to optimal virtual care in this field are lacking. As such, the objective of our Canadian Consensus Panel was to develop clinical practice guidelines related to the provision of virtual care for children, adolescents, and emerging adults living with an eating disorder, as well as their caregivers, during the COVID-19 pandemic and beyond.

METHODS

Using scoping review methodology (with literature in databases from 2000 to 2020 and grey literature from 2010 to 2020), the Grading of Recommendations, Assessment, Development, and Evaluation system, the Appraisal of Guidelines, Research and Evaluation tool, and a panel of diverse stakeholders from across Canada, we developed high quality treatment guidelines that are focused on virtual interventions for children, adolescents, and emerging adults with eating disorders, and their caregivers.

RESULTS

Strong recommendations were supported specifically in favour of in-person medical evaluation when necessary for children, adolescents, and emerging adults, and that equity-seeking groups and marginalized youth should be provided equal access to treatment. For children and adolescents, weak recommendations were supported for telehealth family-based treatment (FBT) and online guided parental self-help FBT. For emerging adults, internet cognitive-behavioural therapy (CBT)-based guided self-help was strongly recommended. Weak recommendations for emerging adults included CBT-based group internet interventions as treatment adjuncts, internet-based relapse prevention Maudsley Model of Anorexia Nervosa Treatment for Adults (MANTRA) guided self-help, telehealth relapse prevention using MANTRA, and guided CBT-based smartphone apps as treatment adjuncts. For caregivers of children and adolescents, weak recommendations were supported for virtual parent meal support training, and moderated online caregiver forums and support groups. For caregivers of emerging adults, guided parental self-help CBT was strongly recommended, and unguided caregiver psychoeducation self-help was weakly recommended.

CONCLUSIONS

Several gaps for future work were identified including the impact of sex, gender, race, and socioeconomic status on virtual care among children, adolescents, and emerging adults with eating disorders, as well as research on more intensive services, such as virtual day hospitals.

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

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.

Feasibility of group Cognitive Remediation Therapy in an adult eating disorder day program in New Zealand

OBJECTIVE

To explore the feasibility of integrating group Cognitive Remediation Therapy (gCRT) into an eating disorder day program in Auckland, New Zealand.

METHOD

A consecutive series of 28 patients took part over an 8-month period in the context of a service audit. Main outcome measures were the Detail and Flexibility Questionnaire (DFlex) and qualitative feedback from patients.

RESULTS

Significant shifts in self-report inefficient cognitive style were observed pre/post gCRT with large effect sizes (Cohen's d_av) for both cognitive rigidity and attention to detail outcomes. Patient feedback was positive, with themes of enjoyment, increased insight, and positive social interaction/esteem boosting in the context of the group emerging.

CONCLUSIONS

Support for the acceptability, adaptation, expansion, practicality, and limited-efficacy testing of gCRT in an Australasian day program setting has been found, suggesting integration of this module into existing day treatment programs is merited. Larger scale trials may help delineate the clinical characteristics of good responders.

Cognitive remediation therapy for adolescent inpatients with severe and complex anorexia nervosa: A treatment trial

Cognitive remediation therapy (CRT) is a low-intensity treatment adjunct for individuals with severe and complex anorexia nervosa (AN) with difficulties in globally oriented, flexible thinking. Previously trialled in adults, this study investigated whether individual and group CRT was a feasible, acceptable, and beneficial treatment for 125 adolescent inpatients with severe and complex AN. Seventy patients (mean age = 15.22, SD = 1.44) received 10 sessions of individual CRT, and 55 patients (mean age = 14.89, SD = 1.74) received 10 sessions of group CRT. In individual CRT, 1 patient (1.43%) dropped out, and there were medium-sized improvements in bigger picture thinking and set-shifting, small to large-sized improvements in switching-related initiation and inhibition skills, and large-sized improvements in motivation to recover. Group CRT had higher dropout (9.09%; n = 5) and produced small-sized improvements in global information processing and medium-sized improvements in self-reported cognitive flexibility and high acceptability ratings. Data suggest that a randomised controlled trial for adolescents with AN is warranted.

Cognitive Remediation Therapy for Adolescents with Anorexia Nervosa-Treatment Satisfaction and the Perception of Change

Cognitive remediation therapy (CRT) has recently been developed for children and adolescents with anorexia nervosa (AN). It focuses on decreasing rigid cognitions and behaviors, as well as increasing central coherence. Overall, CRT has been proven feasible for young individuals with AN, but little is known regarding the specifics of its feasibility, and the perception of change associated with the intervention. Consequently, the aim of the current study was to explore service users’ perspective on CRT with a specific focus on treatment delivery, treatment content, and perceived change. Twenty adolescents (age 13–18) with AN participated in a 10-session course of CRT. A 20-item treatment evaluation questionnaire was administered at the end of treatment, focusing on four aspects of the intervention: (1) general attitudes towards treatment, (2) treatment specifics, (3) the perception of change and (4) the patient-therapist relation. The main findings suggest high levels of treatment satisfaction, but somewhat limited perceptions of change. The current study is one of the most detailed accounts of adolescents’ perspective on CRT published on eating disorders, and highlights several important aspects of the treatment viewed through the eye of the receiver.

Group Qigong for Adolescent Inpatients with Anorexia Nervosa: Incentives and Barriers

Background

Qigong is a mind-body intervention focusing on interoceptive awareness that appears to be a promising approach in anorexia nervosa (AN). In 2008, as part of our multidimensional treatment program for adolescent inpatients with AN, we began a weekly qigong workshop that turned out to be popular among our adolescent patients. Moreover psychiatrists perceived clinical benefits that deserved further exploration.

Methods and findings

A qualitative study therefore sought to obtain a deeper understanding of how young patients with severe AN experience qigong and to determine the incentives and barriers to adherence to qigong, to understanding its meaning, and to applying it in other contexts. Data were collected through 16 individual semi-structured face-to-face interviews and analyzed with the interpretative phenomenological analysis method. Eleven themes emerged from the analysis, categorized in 3 superordinate themes describing the incentives and barriers related to the patients themselves (individual dimension), to others (relational dimension), and to the setting (organizational dimension). Individual dimensions associated with AN (such as excessive exercise and mind-body cleavage) may curb adherence, whereas relational and organizational dimensions appear to provide incentives to join the activity in the first place but may also limit its post-discharge continuation. Once barriers are overcome, patients reported positive effects: satisfaction associated with relaxation and with the experience of mind-body integration.

Conclusions

Qigong appears to be an interesting therapeutic tool that may potentiate psychotherapy and contribute to the recovery process of patients with AN. Further analysis of the best time window for initiating qigong and of its place in overall management might help to overcome some of the barriers, limit the risks, and maximize its benefits.

Central Coherence in Eating Disorders: A Synthesis of Studies Using the Rey Osterrieth Complex Figure Test

Background

Large variability in tests and differences in scoring systems used to study central coherence in eating disorders may lead to different interpretations, inconsistent findings and between study discrepancies. This study aimed to address inconsistencies by collating data from several studies from the same research group that used the Rey Osterrieth Complex Figure Test (Rey Figure) in order to produce norms to provide benchmark data for future studies.

Method

Data was collated from 984 participants in total. Anorexia Nervosa, Bulimia Nervosa, recovered Anorexia Nervosa, unaffected family members and healthy controls were compared using the Rey Figure.

Results

Poor global processing was observed across all current eating disorder sub-groups and in unaffected relatives. There was no difference in performance between recovered AN and HC groups.

Conclusions

This is the largest dataset reported in the literature and supports previous studies implicating poor global processing across eating disorders using the Rey Figure. It provides robust normative data useful for future studies.

How anorexia nervosa patients with high and low autistic traits respond to group Cognitive Remediation Therapy

BACKGROUND

The current study aimed to evaluate group Cognitive remediation therapy (CRT) inpatients with Anorexia Nervosa (AN). We aimed to examine the treatment response of group CRT in AN patients with high or low levels of autistic traits.

METHODS

Thirty-five in patients with an AN diagnosis received group CRT intervention for 6 sessions in a national eating disorder unit. All participants completed self-report questionnaires on thinking styles and motivation before and after the intervention.

RESULTS

Patients with low autistic traits had statistically significant medium size effect improvements in self-reported thinking style scales as well as confidence (ability) to change. Patients with high autistic traits showed no statistically significant improvements in any outcome measure.

CONCLUSIONS

The brief group format CRT intervention improves self-reported cognitive and motivational aspects in people with AN without autistic traits. For patients with higher autistic traits brief group CRT does not improve self-reported cognitive style or motivation. This finding suggests that brief group format CRT might not be the best suited format for individuals with elevated autistic traits and individual or more tailored CRT should be explored.

Benefits of group cognitive remediation therapy in anorexia nervosa: case series

Background

Cognitive remediation therapy (CRT) is a treatment targeting cognitive difficulties in psychiatric disorders. CRT has been used with patients with severe anorexia nervosa (AN) in individual and group formats. Research of group CRT in AN is limited.

Methods

Evaluation of a series of CRT groups delivered in inpatient and intensive daycare services was performed. Participants’ self-reported cognitive flexibility and central coherence, as well as motivation to change were assessed pre- and post-group. Additionally, patients’ evaluative feedback was collected after completion of the group.

Results

There was a significant improvement in the patients’ self-reported cognitive flexibility and bigger picture thinking, as well as in their self-efficacy to change. The feedback questionnaires highlighted that patients found the sessions useful and reported confidence in using some of the skills and strategies they learnt in the group.

Conclusion

In line with evidence from small-scale reports, this larger scale case series study indicates that group CRT leads to increased flexibility and bigger picture thinking, as well as improved confidence in the ability to change for participants. CRT in a group format seems to be a practical and helpful intervention for patients with AN in intensive treatment programmes.

Interventions for the Carers of Patients With Eating Disorders

The aim of this study is to evaluate the recent literature on carers/parenting interventions for people with eating disorders. Interesting and important new findings are highlighted as well as the implications that this may have for treatment. We have reviewed and critically analysed the recent literature. Close others often play an important role in recognising the early signs of eating disorders and accessing and implementing treatment. Their role in helping with recovery is to give support and hold a united front themselves and with the professional team to avoid those common interpersonal reactions that adversely impact on outcome such as accommodating to the illness and reacting with high expressed emotion (overprotection and hostility). Managing this role is difficult, and coping resources are often strained. Carers ask for and are now getting expert training in skills to manage this role. There is an overlap between carer/parenting interventions and family therapies. The interface with close others is critical both for early recognition and access and implementation of treatment. Interventions which equip families and close others with the skills to manage eating disorder behaviours are showing potential at improving outcomes.

Cognitive remediation therapy for eating disorders

PURPOSE OF REVIEW

This review compares the literature on cognitive remediation therapy (CRT) for eating disorders with findings in the field of schizophrenia, and discusses future directions for CRT for eating disorders.

RECENT FINDINGS

First studies using a randomized controlled trial design show the added value of CRT for eating disorders. Patients reported lessened symptoms and further improvements in quality of life and cognitive flexibility. Furthermore, the acceptability of the intervention was good and attrition rates for CRT itself were low. Research into the use of cognitive remediation for schizophrenia is extensive and the results on global cognition appeared to be robust at post-treatment and durable at follow-up, with small to medium effect sizes. Recent articles within the field of schizophrenia emphasize the necessity of intrinsic motivation to translate cognitive gains into actual changes in everyday life.

SUMMARY

A next step is to examine the impact of CRT for eating disorders on motivation. It is also important to focus on the transdiagnostic use of CRT, considering the overlap in cognitive inefficiencies between eating disorders. Another important step may be to develop effective personalized methods of CRT by taking into account individual differences in cognitive processes most relevant to improvement in outcome.
