A Review of Family Therapy as an Effective Intervention for Anorexia Nervosa in Adolescents

Clinical Intervention Strategies and Family Dynamics in Adolescent Eating Disorders: A Scoping Review for Enhancing Early Detection and Outcomes

Background: This systematic review investigated the impact of familial factors on individuals aged 10-17 who have clinical signs or symptoms of eating disorders. Simultaneously, it scrutinized the involvement of the family in therapy, as well as other forms of intervention. Methods: The PsycINFO, PubMed, and Scopus databases were used to search for research material comprehensively. After applying specific criteria, 46 articles were deemed suitable and included in the systematic review. The study comprised a cohort of 4794 adolescents who received a diagnosis of either Anorexia Nervosa (AN), Bulimia Nervosa (BN), or Binge-Eating Disorder (BED). In addition, controls were utilized for 1187 adolescents, 1563 parents, 1809 siblings, and 11 other relatives. Results: The connection between family factors and eating disorders is primarily determined by the families' level of functioning, satisfaction with the family dynamic, parents' attitudes toward their children, and the role of food within the family system. Family Therapy was the most used psychotherapeutic approach in the treatment of AN. The incidence of reports in BN closely paralleled that of Cognitive-Behavioral Therapy (CBT) models. Articles about (Enhanced) CBT were exclusively associated with BED. Conclusions: Family-based approaches are crucial in comprehending, preventing, and addressing eating disorders in adolescents. Incorporating the study of family dynamics and actively engaging families in the treatment process can significantly enhance recovery rates and decrease the occurrence of relapses.

Adaptations of cognitive remediation therapy for adolescents with anorexia nervosa for delivery via telehealth

OBJECTIVE

The COVID-19 pandemic hastened a transition to treatment delivery via telehealth. While barriers still exist, the increased uptake of telehealth has the potential to increase access to mental health treatment for all diagnoses, including eating disorders. Delivery of evidence-based treatment as well as adjunctive treatments, including those that are hard to find in-person, have been modified to virtual format to increase accessibility and allow for continuity of care for adolescents with anorexia nervosa.

METHOD

We describe how to modify and deliver Cognitive Remediation Therapy for youth with anorexia nervosa (CRT-AN) via a telehealth platform. Preliminary and practical guidance for best practice for both group and individual delivery is established.

RESULTS

With minimal modifications, CRT-AN can be delivered via telehealth for both individual and group delivery. More disengagement in group delivery was noted; however, overall application of the treatment via a remote platform was observed.

DISCUSSION

As more treatment moves to a telehealth format, highlighting how an adjunctive treatment like CRT-AN can combined with other treatments in a telehealth format has the potential to increase research in its implementation and furthermore increase its dissemination.

PUBLIC SIGNIFICANCE

Cognitive Remediation Therapy for Anorexia Nervosa (CRT-AN) requires significant manipulation of materials and supplementary human guidance. Suggestions for how to modify CRT-AN for remote delivery via telehealth are provided. Modifications grew out of immediate changes made during the beginning of the COVID-19 pandemic and can be used to inform changes therapists and programs can make to continue to or begin to use CRT-AN in a remote fashion.

"I'm still here, but no one hears you": a qualitative study of young women's experiences of persistent distress post family-based treatment for adolescent anorexia nervosa

BACKGROUND

Family-based treatment (FBT) is the current treatment of choice for adolescent AN based on positive outcomes that include weight restoration in around two-thirds of adolescents. Nevertheless around a quarter drop-out from treatment, particularly in the earlier phases, and a notable proportion of treated adolescents are reported to experience ongoing psychological distress during and post-treatment. This study explores the under-researched experiences of these adolescents.

METHOD

Fourteen participants from Australia, New Zealand and the United Kingdom were interviewed about their experiences of FBT. An inductive thematic analysis of interview transcript data generated key themes related to their experiences, identity negotiations and the discursive materials these used to construct these.

RESULTS

The participants identified working as a family unit as key to their recovery, highlighting the importance of family therapy interventions for adolescent AN. However, they perceived an almost exclusive focus on weight restoration in the first phase of FBT was associated with experiences that included a relative neglect of their psychological distress and a loss of voice. Key within these experiences were processes whereby the adolescent engaged in identity negotiation and (re)claiming of their voice and implicit in their family standing with them in the treatment was that their life was worth saving. What was noted as most helpful was when therapists advocated and took into consideration their unique needs and preferences and tailored treatment interventions to these.

CONCLUSIONS

There is a need to develop and research treatments that address, from the outset of treatment, the adolescents' psychological distress (including as experienced in the context of their weight restoration). This should be with priority accorded to the adolescent's voice and identity negotiations, as they and their families take steps to address the physical crisis of AN and in doing so, support more holistic and durable recovery.

Universal parental support for parents of adolescents: Who wants municipality-based parental support and in what form?

Parenting a child through adolescence can be a challenge for many parents; adolescents go through notable developmental, physical, and psychological changes that affect the relationships around them. Most parents find parental support during these years important. These young people's relationships with their parents are important to their mental health, but although parental support is universally available to parents of younger children, it is still scarce for parents of adolescents. The aim of this study was to explore what factors are associated with interest in universal parental support through telephone interviews and questionnaires with 223 parents of 13- to 17-year-olds. Parents' interest in parental support was linked to their own anxious mood, their lower perceived parental capacity, their perception of the child as having psychiatric problems, the parents' perception of their adolescents' openness about things and their perception of the adolescent's overall difficulties in daily life due to psychiatric symptoms. The results show that lighter forms of support such as lectures or seminars were more appealing to parents with higher social status. Offering community-based individual counseling and leader-led parent training groups therefore has the potential to reach parents with difficulties more equally, while offering support only through lectures and seminars could increase the inequality between parents in different social situations.

Orthorexia Nervosa and Eating Disorder Symptoms in Registered Dietitian Nutritionists in the United States

BACKGROUND

Registered dietitian nutritionists are trained to identify optimal food choices for clients based on medical state and lifestyle. Orthorexia nervosa (ON) is a proposed disorder related to obsessions about eating healthfully. Eating disorders (EDs) are serious mental illnesses with symptoms related to eating, body image, and self-esteem. Both ON and EDs are more common among RDNs than the general population.

OBJECTIVE

This study examined the prevalence of ON and EDs in RDNs in the United States and, among this sample, assessed whether the presence of ON symptoms related to symptoms of EDs, including weight, shape, eating, and restraint.

DESIGN

A cross-sectional design compared responses for participants after dividing into three groups: those scoring at-risk for ON, those with a current or past ED, and a comparison group.

PARTICIPANTS

A sample of 2,500 RDNs were invited to complete surveys electronically; 636 responses were received.

MAIN OUTCOME MEASURES

Scores on the Orthorexia Nervosa Questionnaire (ORTO-15) and Eating Disorder Examination Questionnaire (EDE-Q) determined prevalence of ON and EDs. Differences in these measures, and body mass index were compared among the three groups.

STATISTICAL ANALYSES

Analysis of variance and χ² analyses were used to compare the groups.

RESULTS

For the entire sample, scores on the ORTO-15 suggested 49.5% were at risk for ON, and scores on the EDE-Q suggested 12.9% were at risk for an ED, with 8.2% of RDNs self-disclosing treatment for an ED. Both the group disclosing ED treatment and the group at risk for ON had a lower mean body mass index, lower scores on the ORTO-15, and higher scores on the EDE-Q and all its subscales than the comparison group.

CONCLUSIONS

Clarifying the relationship between ON and EDs is warranted because ON symptoms appear to be associated not only with disturbances in eating, but also with elevated shape and weight concerns.

An Exploratory Evaluation of the Family Meal Intervention for Adolescent Anorexia Nervosa

Although weight restoration is a crucial factor in the recovery of anorexia nervosa (AN), there is scarce evidence regarding which components of treatment promote it. In this paper, the author reports on an effort to utilize research methods in her own practice, with the goal of evaluating if the family meal intervention (FMI) had a positive effect on increasing weight gain or on improving other general outcome measures. Twenty-three AN adolescents aged 12-20 years were randomly assigned to two forms of outpatient family therapy (with [FTFM] and without [FT]) using the FMI, and treated for a 6-month duration. Their outcome was compared at the end of treatment (EOT) and at a 6-month posttreatment follow-up (FU). The main outcome measure was weight recovery; secondary outcome measures were the Morgan Russell Global Assessment Schedule (MRHAS), amenorrhea, general psychological symptoms, and eating disorder symptoms. The majority of the patients in both groups improved significantly at EOT, and these changes were sustained through FU. Given its primarily clinical nature, findings of this investigation project preclude any conclusion. Although the FMI did not appear to convey specific benefits in causing weight gain, clinical observation suggests the value of a flexible stance in implementation of the FMI for the severely undernourished patient with greater psychopathology.

Culturally Relevant Family Therapy Practice with Parents of Children and Adolescents

BACKGROUND

India is diverse in culture, with multiple aspects that may not match with the Western societal picture. Hence, it has often been seen that therapists encounter unique aspects of therapy that is faced during actual practice, which is never written in any textbook or research papers. Substantial information is present through both outcome (efficacy and effectiveness) studies and process research, but it has very little impact of actual Marital and Family Therapy (MFT) practice. This paper throws light into "how" and "what" of family therapy with parents of children/adolescents having psychiatric disorders.

MATERIALS AND METHODS

Focused group discussion was conducted with practicing family therapists and mental health professionals working in Psychiatric Tertiary Hospital (National Institute of Mental Health and Neurosciences, Bengaluru, Karnataka, India). Qualitative analysis was done to disseminate process issues in therapy.

RESULTS

Aspects that are vital for families having children and adolescent with psychiatric disorders include: Academic decline and loss of parental control as main reasons for seeking help, integration of models is noted to be beneficial, therapeutic alliance, intake sessions, conjoint sessions and individual sessions are important, cultural issues like gender of therapist, their cultural belief model, therapist's cultural competence need to be taken into consideration.

CONCLUSIONS

Challenges and way-outs to overcome these has been mentioned and implications discussed.

Favorable effects of clearly defined interventions by parents at the start of treatment of adolescents with restrictive eating disorders

OBJECTIVE

To study the effect of clearly defined and decisive parental interventions at the start of treatment of restrictive eating disorders (ED) in adolescents.

METHOD

Forty-seven adolescents with ED (anorexia nervosa = 6, bulimia nervosa = 1, EDNOS = 40) and their families participated. Parents were advised to (1) keep the adolescent home from school, (2) eat all meals together with the adolescent, (3) prevent any form of exercise, and (4) prevent vomiting during the first week of treatment. Weight change was followed up to three months and EDE-Q administered at start of treatment and at three months.

RESULTS

Thirty (64%) of the families accomplished all four interventions during the first week of treatment. Their adolescents gained ∼ 1 kg of weight at one week, 2 kg at one month, and 4 kg at three months while adolescents in families who did not accomplish all four interventions gained only 1.4 kg up to three months. Scores on the EDE-Q decreased during treatment and in adolescents of families who accomplished all four interventions they were in the range of a reference population.

DISCUSSION

Decisive parental management of eating disturbed behaviors at the start of treatment of adolescents with ED promotes later clinical outcome. The finding supports the view that family based therapies are effective in adolescent ED. Results has to be followed up for evaluation of the long term effects of this type of intervention.

Early weight gain in family-based treatment predicts greater weight gain and remission at the end of treatment and remission at 12-month follow-up in adolescent anorexia nervosa

OBJECTIVE

To Identify whether early weight gain in family-based treatment (FBT) predicted greater weight and remission at end of FBT and 12-month follow-up.

METHOD

Eighty-two adolescents, with anorexia nervosa, participated in a randomized control trial comparing brief hospitalization for medical stabilization and hospitalization for weight restoration to 90% expected body weight (EBW) (1:1), followed by 20 sessions of FBT. Sixty-nine completed trial protocol. Receiver operating characteristic analyses were conducted investigating whether early weight-gain in FBT predicted outcomes at end of FBT and 12-month follow-up. Participants were analyzed according to their original randomization and as a combined set. Binary logistic regression was used to control for randomization arm effect in combined set analysis.

RESULTS

Weight gain greater than 1.8 kg at FBT Session 4 predicted greater %EBW (99.18 SD = 6.93 vs. 92.79 SD = 7.74, p < .05) and remission at end of FBT (46% vs. 11%, p < .05) and at 12-month follow-up (64% vs. 36%, p = .05). Binary logistic regression confirmed weight gain greater than 1.8 kg predicted remission (p < .05) while treatment arm randomization did not add significantly to the model.

DISCUSSION

Early weight gain has potential to distinguish likely responders in FBT from those who may need more intensive intervention to achieve remission offering the potential to improve outcomes.

Incorporating positive body image into the treatment of eating disorders: A model for attunement and mindful self-care

This article provides a model for understanding the role positive body image can play in the treatment of eating disorders and methods for guiding patients away from symptoms and toward flourishing. The Attuned Representational Model of Self (Cook-Cottone, 2006) and a conceptual model detailing flourishing in the context of body image and eating behavior (Cook-Cottone et al., 2013) are discussed. The flourishing inherent in positive body image comes hand-in-hand with two critical ways of being: (a) having healthy, embodied awareness of the internal and external aspects of self (i.e., attunement) and (b) engaging in mindful self-care. Attunement and mindful self-care thus are considered as potential targets of actionable therapeutic work in the cultivation of positive body image among those with disordered eating. For context, best-practices in eating disorder treatment are also reviewed. Limitations in current research are detailed and directions for future research are explicated.

Royal Australian and New Zealand College of Psychiatrists clinical practice guidelines for the treatment of eating disorders

OBJECTIVES

This clinical practice guideline for treatment of DSM-5 feeding and eating disorders was conducted as part of the Royal Australian and New Zealand College of Psychiatrists (RANZCP) Clinical Practice Guidelines (CPG) Project 2013-2014.

METHODS

The CPG was developed in accordance with best practice according to the National Health and Medical Research Council of Australia. Literature of evidence for treatments of anorexia nervosa (AN), bulimia nervosa (BN), binge eating disorder (BED), other specified and unspecified eating disorders and avoidant restrictive food intake disorder (ARFID) was sourced from the previous RANZCP CPG reviews (dated to 2009) and updated with a systematic review (dated 2008-2013). A multidisciplinary working group wrote the draft CPG, which then underwent expert, community and stakeholder consultation, during which process additional evidence was identified.

RESULTS

In AN the CPG recommends treatment as an outpatient or day patient in most instances (i.e. in the least restrictive environment), with hospital admission for those at risk of medical and/or psychological compromise. A multi-axial and collaborative approach is recommended, including consideration of nutritional, medical and psychological aspects, the use of family based therapies in younger people and specialist therapist-led manualised based psychological therapies in all age groups and that include longer-term follow-up. A harm minimisation approach is recommended in chronic AN. In BN and BED the CPG recommends an individual psychological therapy for which the best evidence is for therapist-led cognitive behavioural therapy (CBT). There is also a role for CBT adapted for internet delivery, or CBT in a non-specialist guided self-help form. Medications that may be helpful either as an adjunctive or alternative treatment option include an antidepressant, topiramate, or orlistat (the last for people with comorbid obesity). No specific treatment is recommended for ARFID as there are no trials to guide practice.

CONCLUSIONS

Specific evidence based psychological and pharmacological treatments are recommended for most eating disorders but more trials are needed for specific therapies in AN, and research is urgently needed for all aspects of ARFID assessment and management.

Pediatric feeding and eating disorders: current state of diagnosis and treatment

The Diagnostic and Statistical Manual of Mental Disorders now recognizes six primary feeding and eating disorders including pica, rumination disorder, avoidant/restrictive food intake disorder, anorexia nervosa, bulimia nervosa and binge-eating disorder. Guided by research from the past 3 years, the current review outlines diagnostic criteria for each disorder, their clinical correlates and treatment options. Recent modifications to diagnostic criteria will likely help to improve treatment outcomes and prognosis. Nevertheless, several concerns remain regarding the validity of current diagnostic criteria for youth, including the clinical relevance of the size and frequency of binge eating episodes. Additionally, the lack of randomized controlled trials has led to an overreliance on data from quasi-experimental studies, case series and single case studies that impede development of strong clinical recommendations for treating feeding and eating disorders. Recommendations for future research include identifying empirically supported treatments and prevention programs focused on early markers of pediatric feeding and eating concerns.

Mapping the evidence for the prevention and treatment of eating disorders in young people

ABSTRACT

Eating disorders often develop during adolescence and young adulthood, and are associated with significant psychological and physical burden. Identifying evidence-based interventions is critical and there is need to take stock of the extant literature, to inform clinical practice regarding well-researched interventions and to direct future research agendas by identifying gaps in the evidence base.

AIM

To investigate and quantify the nature and distribution of existing high-quality research on the prevention and treatment of eating disorders in young people using evidence mapping methodology.

METHOD

A systematic search for prevention and treatment intervention studies in adolescents and young adults (12-25 years) was conducted using EMBASE, PSYCINFO and MEDLINE. Studies were screened and mapped according to disorder, intervention modality, stage of eating disorder and study design. Included studies were restricted to controlled trials and systematic reviews published since 1980.

RESULTS

The eating disorders evidence map included 197 trials and 22 systematic reviews. Prevention research was dominated by trials of psychoeducation (PE). Bulimia nervosa (BN) received the most attention in the treatment literature, with cognitive behavioural therapy (CBT) and antidepressants the most common interventions. For anorexia nervosa (AN), family based therapy (FBT) was the most studied. Lacking were trials exploring treatments for binge eating disorder (BED) and eating disorder not otherwise specified (EDNOS). Relapse prevention strategies were notably absent across the eating disorders.

CONCLUSIONS

Despite substantial literature devoted to the prevention and treatment of eating disorders in young people, the evidence base is not well established and significant gaps remain. For those identified as being at-risk, there is need for prevention research exploring strategies other than passive PE. Treatment interventions targeting BED and EDNOS are required, as are systematic reviews synthesising BN treatment trials (e.g., CBT, antidepressants). FBTs for AN require investigation against other validated psychological interventions, and the development of relapse prevention strategies is urgently required. By systematically identifying existing interventions for young people with eating disorders and exposing gaps in the current literature, the evidence map can inform researchers, funding bodies and policy makers as to the opportunities for future research.
