Parental expressed emotion of adolescents with anorexia nervosa: outcome in family-based treatment

Remote family education and support program for parents of patients with adolescent and early adulthood eating disorders based on interpersonal psychotherapy: study protocol for a pilot randomized controlled trial

BACKGROUND

In cases of adolescent and early adulthood eating disorders, despite the importance of the patients' relationship with their parents, conflict and confusion frequently occur among them. Interpersonal psychotherapy (IPT) is a present-focused psychotherapy that emphasizes the interpersonal context of symptoms. We developed a remote family education and support program exclusively for parents of patients with eating disorders, based on the principle of IPT. The use of IPT is expected to reduce conflicts in the patient-parent relationship. Consequently, parents will be better able to listen to patients, and patients will be better able to express their thoughts and desires. In this study, we describe the protocol for a randomized controlled trial designed to examine the effectiveness of this program in promoting effective communication in their home based on active listening skills of parents of patients with adolescent and early adulthood eating disorders.

METHODS

Participants will be parents of patients aged 12-29 years with adolescent and early adulthood eating disorders. Individually randomized, parallel-group trial design will be employed. Seventy participants will be allocated to one of two treatment conditions: (1) remote family education and support program (four, 150 min weekly group sessions) for parents plus treatment-as-usual for patients (consultation by physicians or no treatment), or (2) waiting for the control condition (parents will wait to start the program for 8 weeks) plus treatment-as-usual for patients. The primary outcome measure will be parents' active listening ability as measured by the Active Listening Attitude Scale at 8 weeks after randomization. Additionally, perception of social support (Social Provision Scale-10 item), loneliness (UCLA Loneliness Scale), mental health status (K6), family function (Family Assessment Device), and parent-evaluated eating disorder symptoms (Anorectic Behavior Observation Scale) will be assessed. Data from the intention-to-treat sample will be analyzed 8 weeks after randomization.

DISCUSSION

This is the first study to evaluate the effectiveness of a family education and support program for parents of patients with adolescent and early adulthood eating disorders based on IPT. If this type of intervention is effective, although indirect, it could be a new support method for this patient population.

A case-control study to differentiate parents' personality traits on anorexia nervosa and affective disorders

Eating disorders (ED) and affective disorders (AD) in adolescent population and several investigations have pointed out that specific family dynamics play a major role in the onset, course, and maintenance of both disorders. The aim of this study was to extend the literature of this topic by exploring differences between parents' personality traits, coping strategies, and expressed emotion comparing groups of adolescents with different mental conditions (anorexia nervosa vs. affective disorder vs. control group) with a case-control study design. A total of 50 mothers and 50 fathers of 50 girls with anorexia nervosa (AN), 40 mothers and 40 fathers of 40 girls with affective disorder (AD), and 50 mothers and 50 fathers of 50 girls with no pathology that conformed the control group (CG) were measured with the Temperament and Character Inventory (TCI), the COPE Inventory, the Family Questionnaire (FQ), and psychopathology variables, anxiety, and depression. Both parents of girls with AN showed a significant difference in personality, coping strategies, and expressed emotion compared to both parents in the CG, while they presented more similarities to parents of girls in the AD group. Identifying personality traits, expressed emotion, coping strategies, and psychopathology of parents and their daughters will allow improvements in the interventions with the adolescents, parents, and families.

Expressed emotion and early treatment response in family-based treatment for adolescent anorexia nervosa

This study examined the effect of pre-treatment levels of parental expressed emotion (EE) on early treatment response for adolescent anorexia nervosa (AN). Data were collected from 121 adolescents, ages 12-18, who met DSM-IV criteria for AN excluding the amenorrhea criterion, and their parents. Participants were randomized to family-based treatment (FBT) or adolescent-focused therapy (AFT). To examine the effects of different thresholds of EE, we used two different levels of EE in analyses. Results demonstrated that adolescents who had at least one parent with elevated EE indicated by a lower threshold (i.e. even mild levels) at baseline were less likely to achieve an early treatment response, suggesting that EE might interfere with treatment success from the start of treatment. When high EE was defined by a higher threshold, these effects were no longer significant, regardless of treatment type (FBT or AFT). These findings suggest that adolescents with AN may be more sensitive to EE than other mental illnesses, such that lower thresholds of EE impact the speed with which they are able to reduce symptoms and gain weight in treatment. It may be necessary to target parental EE prior to or early in treatment or pivot to parent-focused treatment to change the trajectory of treatment response. Future research is needed to explore ways parental EE can be reduced.

Emotion coaching skills as an augmentation to family-based therapy for adolescents with anorexia nervosa: A pilot effectiveness study with families with high expressed emotion

OBJECTIVE

To examine the feasibility and acceptability of augmenting family-based treatment (FBT) for adolescents with anorexia nervosa (AN) or atypical anorexia nervosa (AAN) with a parent emotion coaching intervention (EC) focused on reducing parent expressed emotion.

METHOD

In this pilot effectiveness trial, families of adolescents with AN/AAN exhibiting high expressed emotion received standard FBT with either (1) EC group or (2) support group (an attention control condition focused on psychoeducation).

RESULTS

Forty-one adolescents with AN or AAN were recruited (88% female, Mage  = 14.9 ± 1.6 years, 95% White: Non-Hispanic, 1% White: Hispanic, 1% Bi-racial: Asian). Most study adolescents were diagnosed with AN (59%) while 41% were diagnosed with AAN. Participating parents were predominantly mothers (95%). Recruitment and retention rates were moderately high (76% and 71%, respectively). High acceptability and feasibility ratings were obtained from parents and interventionists with 100% reporting the EC intervention was "beneficial"-"very beneficial." The FBT + EC group demonstrated higher parental warmth scores at post-treatment compared to the control group (standardized effect size difference, d = 1.58), which was maintained at 3-month follow-up. Finally, at post-treatment, the FBT + EC group demonstrated higher rates of full remission from AN/AAN (40%) compared to FBT + support (27%), and were nine times more likely to be weight restored by 3-month follow-up.

DISCUSSION

Augmenting FBT with emotion coaching for parents with high expressed emotion is acceptable, feasible, and demonstrates preliminary effectiveness.

PUBLIC SIGNIFICANCE

Family based treatment for AN/AAN is the recommended treatment for youth but families with high criticism/low warmth are less likely to respond to this treatment. Adding a parent emotion coaching group (EC) where parents learn to talk to their adolescents about tough emotions is feasible and well-liked by families.

Moderators of treatment effect in a randomised controlled trial of single- and multi-family therapy for anorexia nervosa in adolescents and emerging adults

INTRODUCTION

Multi-family therapy for anorexia nervosa (MFT-AN) is a novel, group-based intervention that intensifies single-family therapy for anorexia nervosa (FT-AN), with the aim of improving outcomes. The current study explored treatment moderators in a randomised controlled trial (N = 167) of FT-AN and MFT-AN for young people (adolescents/emerging adults aged 13-20 years) with anorexia nervosa.

METHODS

Data were analysed using multiple linear regression. Six hypothesised baseline participant and parent factors were tested as possible moderators of treatment effect on end-of-treatment and follow-up percentage of median Body Mass Index (%mBMI); age, eating disorder symptom severity, perceived family conflict (young person and parent ratings) and parent-rated experiences of caregiving (positive and negative).

RESULTS

Greater parent-rated positive caregiving experiences moderated treatment outcomes at follow-up (β = -0.47, 95%CI: -0.91, -0.03, p = 0.04), but not end-of-treatment. Participants who had fewer parent-rated positive caregiving experiences at baseline had higher weight at follow-up if they had MFT-AN compared to FT-AN. No other hypothesised baseline factors moderated treatment outcome (p's > 0.05).

DISCUSSION

The current study suggests MFT-AN may be indicated for families who present with fewer positive caregiving experiences to treatment. The MFT-AN group context may help to promote mentalisation and hope for these families, which may be harder to achieve in single-family treatment. Future research is needed to empirically evaluate how and why MFT-AN supports this group more.

Fathers in the spotlight: parental burden and the effectiveness of a parental skills training for anorexia nervosa in mother-father dyads

PURPOSE

Research on the engagement of fathers in the treatment of childhood psychiatric disorders is scarce. This study aims to investigate differences between mothers and fathers of adolescents with anorexia nervosa regarding parental burden and effectiveness of a parental skills training.

METHODS

Ninety-one mother-father dyads caring for a child with anorexia nervosa participated in an 8-week parental skills training and completed a set of questionnaires assessing parental psychopathology, eating disorder related burden, caregiver skills and expressed emotion at baseline and post-intervention.

RESULTS

Fathers showed lower levels of general psychological distress, depression, anxiety and eating disorder related burden as well as lower emotional overinvolvement compared to mothers. The skills training was effective in reducing parental psychopathology, eating disorder-related burden and emotional overinvolvement as well as in increasing caregiver skills with no differences between mothers and fathers. However, session adherence and the willingness to practice skills between the sessions were slightly lower in fathers.

CONCLUSIONS

These findings show that fathers are a great resource for the child's eating disorder treatment as they may counterbalance maternal emotional overinvolvement and over-protection. Furthermore, this is the first study demonstrating that fathers can profit from a parental skills training for anorexia nervosa in a similar way as mothers.

Augmenting family based treatment with emotion coaching for adolescents with anorexia nervosa and atypical anorexia nervosa: Trial design and methodological report

This article characterizes the design, recruitment, methodology, participant characteristics, and preliminary feasibility and acceptability of the Families Ending Eating Disorders (FEED) open pilot study. FEED augments family-based treatment (FBT) for adolescents with anorexia nervosa (AN) and atypical anorexia nervosa (AAN) with an emotion coaching (EC) group for parents (i.e., FBT + EC). We targeted families high in critical comments and low warmth (assessed by the Five-Minute Speech Sample), known predictors of poor response in FBT. Eligible participants included adolescents initiating outpatient FBT, diagnosed with AN/AAN, ages 12-17, with a parent high in critical comments/low in warmth. The first phase of the study was an open pilot which demonstrated feasibility and acceptability of FBT + EC. Thus, we proceeded with the small randomized controlled trial (RCT). Eligible families were randomized to either 10 weeks of FBT + EC parent group treatment or the 10- week parent support group (control condition). The primary outcomes were parent critical comments and parental warmth, while our exploratory outcome was adolescent weight restoration. Novel aspects of the trial design (e.g., specifically targeting typical treatment non-responders), as well as recruitment and retention challenges in the context of the COVID-19 pandemic are discussed.

Expressed emotion and treatment outcome in higher levels of care for eating disorders

OBJECTIVE

Expressed emotion (EE) among caregivers toward the affected offspring is a negative prognostic indicator for adolescent patients with eating disorders (EDs) in outpatient treatment. Less research has examined its impact on adolescents in higher levels of care (HLOC). The current study examined differences in caregiver EE according to the subtype of anorexia nervosa (AN) (restricting [AN-R] versus binge/purge [AN-BP]), and level of care (LOC). We also examined the main effects of baseline caregiver EE (emotional overinvolvement [EOI] or criticism), AN subtype, and their interaction on eating pathology and depression at discharge.

METHOD

Adolescent patients (N = 203) receiving treatment at HLOCs completed measures of ED pathology (Eating Disorder Examination-Questionnaire) and depression (Patient Health Questionnaire-9) at baseline and discharge, and one caregiver of each patient completed a measure of EE (Family Questionnaire) at baseline.

RESULTS

No differences in caregiver EE were found between patients with AN-R versus AN-BP, or relative to LOC. Caregiver EE did not predict outcome for ED symptoms or depression at discharge.

DISCUSSION

The impact of high caregiver EE may be less substantial at HLOCs than outpatient care given that caregivers are less involved in treatment at HLOCs. Future research is needed to determine if high caregiver EOI leads to poor treatment outcome for adolescents as it does for adults, or whether it is an appropriate expression of care for patients who are ill enough to require HLOC treatment.

PUBLIC SIGNIFICANCE STATEMENT

High caregiver EE was not found to predict treatment outcome for adolescents with eating disorders in higher levels of care (HLOCs), possibly due to the limited involvement of caregivers in HLOCs. However, patients step down to outpatient treatment, where high caregiver EE can have a significant negative impact on outcome. HLOCs should incorporate efforts to reduce high caregiver EE in anticipation of step-down to outpatient treatment.

Predictors of caregiver burden before starting family-based treatment for adolescent anorexia nervosa and associations with weight gain during treatment

PURPOSE

Caregivers play a pivotal role in the success of family-based treatment (FBT) for anorexia nervosa (AN). Caregiver burden is frequently demonstrated in eating disorders (EDs) and may impact FBT outcomes. This study examined factors associated with caregiver burden before starting FBT and whether pre-treatment caregiver burden was associated with weight gain during FBT.

METHODS

Participants included 114 adolescents with AN or atypical AN (mean age = 15.6 years, SD = 1.4) and a primary caregiver (87.6% mothers) who received FBT in the United States. Before starting treatment, participants completed self-report measures of caregiver burden (via the Eating Disorder Symptom Impact Scale), caregiver anxiety, caregiver depression, and ED symptoms. Clinical characteristics and percentage of target goal weight (%TGW) at FBT session 1 and 3 and 6 months after starting treatment were obtained via retrospective chart review. Hierarchical regressions examined predictors of caregiver burden before FBT initiation. Associations between pre-treatment caregiver burden and %TGW gain at 3 and 6 months after starting FBT were assessed with hierarchical regressions.

RESULTS

Caregiver anxiety (p < 0.001), family history of EDs (p = 0.028), adolescent mental health treatment history (p = 0.024), and ED symptoms (p = 0.042) predicted caregiver burden before starting FBT. Pre-treatment caregiver burden was not associated with %TGW gain at 3 or 6 months. Males demonstrated less %TGW gain than females at 3 months (p = 0.010) and 6 months (p = 0.012).

CONCLUSION

Proactively evaluating caregiver burden before starting FBT is suggested. Providing recommendations and/or referrals for identified caregiver vulnerabilities could indirectly impact FBT progress. Males in FBT could require longer courses of treatment and extra vigilance to this demographic is suggested.

Weight restoration in adolescent anorexia: parents' goal-directed processes

BACKGROUND

Parent-led weight restoration is a key intervention of family-based treatment, an empirically supported treatment for adolescent anorexia. Successful outcomes in family-based treatment depend almost entirely on parental action, yet current understandings of this intervention are primarily informed by professional theory and expert perspectives. Comparatively little is known about parents' goals and actions while implementing the treatment, despite goal-directed action being an explicit framework of family-based treatment. This study seeks to investigate parents' involvement in weight restoration from the perspective of the goal-directed actions they construct and engage in themselves and with others. This study focuses on the phenomenon of parent-led weight restoration as a project and addresses the following research question: "How do parents participate in the weight restoration of their adolescent as the adolescent recovers from anorexia nervosa?".

METHOD

This multicase study used the action project method and conceptual framework of contextual action theory to examine four cases of five parents engaged in actions to help their adolescent regain weight and recover from anorexia. Data were collected using multi-part interviews and analyzed according to the action project method and the multicase approach.

RESULTS

Parents' weight restoration projects were identified and grouped based on three common a themes. The primary theme, progressing toward health and well-being, was supported by three key processes: maintaining a holistic focus, trusting, and monitoring progress. Two secondary themes captured actions that were integral to the parents' projects, but with less prominence. Secondary themes were creating capacity, which was supported by three processes (managing emotions to maintain a helpful focus, personal work, and resourcing time and finances), and coordinating and negotiating partnerships. The socio-cultural valuing of the thin ideal emerged as a unique process salient in one case. This study presents a goal-directed and contextual perspective on how parents translated the principles of family-based treatment into their daily lives. It joins a small but growing body of work concerned with generating new understandings and frameworks for practitioners and researchers to enhance the effectiveness of family-based treatment in community settings.

Treatment-engagement fears in family-oriented interventions: validation of the caregiver traps scale for eating disorders

As more caregivers of children (of any age) struggling with an eating disorder are recruited as partners in care, it is important to identify potential barriers to such involvement. The Caregiver Traps Scale for Eating Disorders (CTS-ED) was developed as a measure of caregiver fears with respect to treatment-engagement. The purpose of this study was to evaluate its psychometric properties. One hundred and twenty four parents of children with ED participated in the validation of this instrument. Data were analyzed through exploratory factor analysis. The exploratory factor analysis revealed one factor, accounting for 39% of the variance, with a mean of 3.99 (scale from 1 to 7), indicating that caregivers endorsed clinically significant fears relating to their involvement in their child's treatment. The scale yielded high internal consistency (α = .89). As expected, the CTS-ED was significantly positively correlated with a measure of accommodating and enabling of ED symptoms, and negatively correlated with a measure of parental self-efficacy. This scale shows promise as a measure for clinicians and researchers to identify parental fears that could potentially fuel accommodating, enabling or treatment-interfering behaviors. Suggestions for its utility as a clinical and supervision tool are also provided.Clinical SignificanceDevelopment of an assessment tool to identify caregiver fears with respect to therapy engagement in the context of family-oriented interventions for eating disordersTool has the potential to increase the positive involvement of caregivers to support their child (of any age) with an eating disorderTool can be used clinically and to support self-reflective practices to improve compassionate clinician engagement of caregivers struggling to support their child.

A scoping review of non-specific predictors, moderators, and mediators of family-based treatment for adolescent anorexia and bulimia nervosa: a summary of the current research findings

PURPOSE

This scoping review presents an up-to-date synthesis of the current evidence base for non-specific predictors, moderators, and mediators of family-based treatment (FBT) for adolescent anorexia and bulimia nervosa.

METHODS

We identify ways in which end-of-treatment outcomes have been shown to differ based upon baseline clinical features and person-specific factors and explore psychological mechanisms that may explain differences in treatment response. We draw from this evidence base to outline recommendations for clinical practice, as well as directions for future clinical eating disorder research.

RESULTS

Noted findings from review include that early response in weight gain and parental criticism may be particularly influential in treatment for anorexia nervosa. Further, for adolescents with either anorexia or bulimia nervosa, eating-related obsessionality may be a key intervention target to improve outcomes.

CONCLUSION

In addition to highlighting a need for attention to specific patient- and caregiver-level factors that impact treatment response, recommendations for research and clinical practice include testing whether certain targeted treatments (e.g., exposure-based approaches) may be suitable within the context of FBT for eating disorders.

Expressed emotion and long-term outcome among adolescents with anorexia nervosa

OBJECTIVE

The purpose of the current study is to examine expressed emotion (EE) and long-term treatment outcome among adolescents participating in a randomized controlled trial (RCT) for treatment of anorexia nervosa (AN). It was hypothesized that patients with high EE parents at baseline would show more severe symptoms at end-of-treatment, 12-month follow-up, and 4-year follow-up than patients from low EE families.

METHOD

Secondary data analysis was conducted of original RCT data from a two-site eating disorder treatment trial conducted in the United States. Participants were 121 adolescents with AN who completed measures of EE, eating disorder psychopathology, depression, and self-esteem.

RESULTS

Generalized estimating equations showed that participants who were in the Low EE group achieved a more accelerated drop in depression scores in the context of treatment (first 12 months) than participants in the High EE group. No other significant Group × Time interactions were found.

DISCUSSION

Findings suggest that high parental EE at baseline does not indicate that adolescent patients with AN will fare poorly 4 years later.

"It really presents a struggle for females, especially my little girl": Exploring fathers' experiences discussing body image with their young daughters

Body dissatisfaction in children, particularly young girls, is a growing concern around the world. The home environment can have a strong influence on children's well-being, and parents may contribute to their children's positive or negative body image development. Nearly all research on parent influence on body image has focused on mothers, leaving fathers' attitudes and experiences poorly-understood. To address this gap in the literature, we interviewed 30 fathers (Mage = 40.30; SD = 7.48) of girls between the ages of 5 and 10 about the conversations they have with their daughters regarding body image. Through thematic analysis, we identified three primary themes: barriers to effective communication, combatting negative influences, and strategies for discussing body image. Fathers recognized the importance of talking about body image with their daughters, yet many did not feel confident or competent to do so effectively. They engaged in a variety of strategies to combat adverse cultural influences and encourage self-expression, character development, and mental and physical health in their daughters. However, messages about health were sometimes conflated with messages about thinness or food restriction. Implications for families and future research are discussed.

Parent strategies to support young people experiencing mental health problems in Australia: What is most helpful?

Parents are a critical resource in supporting young people who live with mental health problems. Qualitative research has identified that parents use a wide range of strategies to provide support. However, parents report being unsure which strategies are likely to be helpful, so often struggle in this role. Presently, little empirical evidence exists to assist parents to decide which strategies are likely to be most helpful. This study aimed to explore the parent-perceived helpfulness of parental strategies to support young people living with mental health problems. Data were collected from February to July of 2018, using a cross-sectional, online, anonymous, self-report survey of participants who identified as parenting a young person (15-24 years) diagnosed with a mental health problem (n = 70). Overall, the strategies perceived as most helpful were practical assistance and personal interactions aimed at promoting positive thoughts and feelings and obtaining appropriate treatment. Least helpful strategies tended to be control-type strategies, aimed at behaviour change. Overall, there was good alignment between strategies' helpfulness and frequency of use, however, there were exceptions. These exceptions are likely reflections of the specific context of particular situations as well as parental uncertainty regarding alternative strategies. Generally, perceptions of strategies' helpfulness were unrelated to parent or child characteristics. However, helpfulness of strategies was associated with parents' satisfaction with their relationship with the young person. Parents' collective experience-based perceptions about the helpfulness of strategies used to support young people experiencing mental health problems can be harnessed to inform mental health practitioners' advice to parents and contribute to better mental health outcomes for young people.

Caregiving experience and expressed emotion among parents of adolescents suffering from anorexia nervosa following illness onset

The aim of this study was to better understand the relationship between parents' experience of caregiving and expressed emotion during the early stage of their child's eating disorder. Fifty mothers and 38 fathers of adolescents suffering from anorexia nervosa and hospitalized for the first time participated in this study. They completed the Experience of Caregiving Inventory, a measure of the negative and positive aspects of the caregiving experience, and the Family Questionnaire, which measured the different dimensions of expressed emotion, namely emotional over-involvement and critical comments. Results showed that caregiving experience is significantly and positively correlated to expressed emotion. Among the negative aspects of caregiving, sense of loss contributed most to emotional over-involvement, while difficult behaviours contributed most to critical comments. The results suggest that parents' perceptions of their child and child's future are strongly related to their tendency to be over-involved. The perception of disruptive behaviours in their child could be one of the principal triggers or exacerbating factors of parents' critical attitudes.

Family-based treatment for transition age youth: the role of expressed emotion and general family functioning

The aim of this study was to investigate changes in family functioning and parental expressed emotion (EE) in parents and transition age youth (18 to 25 years old) with Anorexia Nervosa participating in Family-Based Treatment for Transition Age Youth (FBT-TAY). Further, we examined whether perceived family functioning and EE were associated with changes in eating disorder behaviour and weight in participants at end-of-treatment and three months post-treatment. Generalized estimating equations revealed that changes in family functioning significantly improved from baseline to end-of-treatment (p = .0001), and baseline to three months post-treatment (p = .0001) in parents; and from baseline to end-of-treatment (p = .011), and baseline to three months post-treatment (p = .0001) in transition age youth. The level of parental EE did not differ significantly from baseline to end-of-treatment (p = .379), or baseline to three months post-treatment (p = .185). A series of Ordinary Least Square regression models demonstrated that changes in perceived family functioning and EE were not significantly associated with changes in eating disorder behaviour and weight restoration of transition age youth at end-of-treatment and three months post-treatment. Overall, perceptions of family functioning improved during the course of FBT-TAY, but EE did not.

Predictors of Weight Restoration in a Day-Treatment Program that Supports Family-Based Treatment for Adolescents with Anorexia Nervosa

Family-Based Treatment (FBT) is considered a first-line treatment for adolescents with eating disorders. The traditional outpatient model of FBT may not, however, be appropriate for adolescents requiring more intensive treatment due to severe medical complications or insufficient progress in traditional outpatient FBT. In response, efforts have been made to incorporate FBT into higher levels of care, such as day-treatment programs (DTPs), for families who need additional support. Little is known about the factors that predict weight restoration for DTPs intended to support FBT. The current study examined the ability of specific adolescent and caregiver variables to predict weight restoration at discharge for adolescents with anorexia nervosa (AN) enrolled in a skills-based DTP that supports FBT. Participants were 87 adolescents diagnosed with AN and their caregivers (N = 74). Body Mass Index (BMI) at baseline, percentage of Expected Body Weight (%EBW) gain within the first 4 weeks, and caregiver empowerment level at baseline were found to significantly predict weight restoration. Higher BMI at baseline and higher %EBW gained in the first 4 weeks of treatment were predictive of weight restoration, whereas lower caregiver empowerment at baseline was predictive of weight restoration. Additionally, the rate of weight gain is reported for this DTP grounded in FBT philosophy.

Family therapy approaches for anorexia nervosa

BACKGROUND

Anorexia nervosa (AN) is characterised by a failure to maintain a normal body weight due to a paucity of nutrition, an intense fear of gaining weight or behaviour that prevents the individual from gaining weight, or both. The long-term prognosis is often poor, with severe developmental, medical and psychosocial complications, high rates of relapse and mortality. 'Family therapy approaches' indicate a range of approaches, derived from different theories, that involve the family in treatment. We have included therapies developed on the basis of dominant family systems theories, approaches that are based on or broadly similar to the family-based therapy derived from the Maudsley model, approaches that incorporate a focus on cognitive restructuring, as well as approaches that involve the family without articulation of a theoretical approach.This is an update of a Cochrane Review first published in 2010.

OBJECTIVES

To evaluate the efficacy of family therapy approaches compared with standard treatment and other treatments for AN.

SEARCH METHODS

We searched the Cochrane Common Mental Disorders Controlled Trials Register (CCMDCTR) and PsycINFO (OVID) (all years to April 2016). We ran additional searches directly on Cochrane Central Register for Controlled Trials (CENTRAL), MEDLINE, Ovid Embase, and PsycINFO (to 2008 and 2016 to 2018). We searched the World Health Organization (WHO) trials portal (ICTRP) and ClinicalTrials.gov, together with four theses databases (all years to 2018). We checked the reference lists of all included studies and relevant systematic reviews. We have included in the analyses only studies from searches conducted to April 2016.

SELECTION CRITERIA

Randomised controlled trials (RCTs) of family therapy approaches compared to any other intervention or other types of family therapy approaches were eligible for inclusion. We included participants of any age or gender with a primary clinical diagnosis of anorexia nervosa.

DATA COLLECTION AND ANALYSIS

Four review authors selected the studies, assessed quality and extracted data. We used a random-effects meta-analysis. We used the risk ratio (with a 95% confidence interval) to summarise dichotomous outcomes and both the standardised mean difference and the mean difference to summarise continuous measures.

MAIN RESULTS

We included 25 trials in this version of the review (13 from the original 2010 review and 12 newly-included studies). Sixteen trials were of adolescents, eight trials of adults (seven of these in young adults aged up to 26 years) and one trial included three age groups: one adolescent, one young adult and one adult. Most investigated family-based therapy or variants. Reporting of trial conduct was generally inadequate, so that in a large number of studies we rated the risk of bias as unclear for many of the domains. Selective reporting bias was particularly problematic, with 68% of studies rated at high risk of bias in this area, followed by incomplete outcome data, with 44% of studies rated at high risk of bias in this area. For the main outcome measure of remission there was some low-quality evidence (from only two studies, 81 participants) suggesting that family therapy approaches might offer some advantage over treatment as usual on rates of remission, post intervention (risk ratio (RR) 3.50, 95% confidence interval (CI) 1.49 to 8.23; I² = 0%). However, at follow-up, low-quality evidence from only one study suggested this effect was not maintained. There was very low-quality evidence from only one trial, which means it is difficult to determine whether family therapy approaches offer any advantage over educational interventions for remission (RR 9.00, 95% CI 0.53 to 153.79; 1 study, N = 30). Similarly, there was very low-quality evidence from only five trials for remission post-intervention, again meaning that it is difficult to determine whether there is any advantage of family therapy approaches over psychological interventions (RR 1.22, 95% CI 0.89 to 1.67; participants = 252; studies = 5; I² = 37%) and at long-term follow-up (RR 1.08, 95% CI 0.91 to 1.28; participants = 200; studies = 4 with 1 of these contributing 3 pairwise comparisons for different age groups; I² = 0%). There was no indication that the age group had any impact on the overall treatment effect; however, it should be noted that there were very few trials undertaken in adults, with the age range of adult studies included in this analysis from 20 to 27. There was some evidence of a small effect favouring family based therapy compared with other psychological interventions in terms of weight gain post-intervention (standardised mean difference (SMD) 0.32, 95% CI 0.01 to 0.63; participants = 210; studies = 4 with 1 of these contributing 3 pairwise comparisons for different age groups; I² = 11%) . Overall, there was insufficient evidence to determine whether there were any differences between groups across all comparisons for most of the secondary outcomes (weight, eating disorder psychopathology, dropouts, relapse, or family functioning measures), either at post-intervention or at follow-up.

AUTHORS' CONCLUSIONS

There is a limited amount of low-quality evidence to suggest that family therapy approaches may be effective compared to treatment as usual in the short term. This finding is based on two trials that included only a small number of participants, and both had issues about potential bias. There is insufficient evidence to determine whether there is an advantage of family therapy approaches in people of any age compared to educational interventions (one study, very low quality) or other psychological therapies (five studies, very low quality). Most studies contributing to this finding were undertaken in adolescents and youth. There are clear potential impacts on how family therapy approaches might be delivered to different age groups and further work is required to understand what the resulting effects on treatment efficacy might be. There is insufficient evidence to determine whether one type of family therapy approach is more effective than another. The field would benefit from further large, well-conducted trials.

"We don't really know what else we can do": Parent experiences when adolescent distress persists after the Maudsley and family-based therapies for anorexia nervosa

BACKGROUND

Maudsley Family Therapy (MFT), and its manualised version, Family-Based Therapy (FBT), are the only well-established treatment interventions for adolescent anorexia nervosa (AN), with treatment efficacy primarily measured by improvements in eating behaviours and weight restoration. A crucial component of this therapy is an intensive home-based refeeding intervention that requires a substantial commitment from parents for up to one year. While this treatment works to restore weight in a proportion of adolescents, very little is known about its impacts on family distress, relationships and identity, including in the 40% of families where the adolescent experiences ongoing eating disorder (ED) symptomatology and/or psychological distress during and post-treatment. Specifically, few studies have investigated the impacts of MFT/FBT treatment on family functioning or on how parents negotiate their identities, or who they understand themselves to be, in the context of this treatment intervention. This is a significant omission, given the substantive role assigned to parents to take responsibility for their child's eating restoration in the first treatment phase. This study seeks to address this gap through a qualitative exploration of parents' experiences of MFT/FBT, in cases where treatment was discontinued and/or their child continued to experience psychological distress post-treatment.

METHODS

13 parents participated in in-depth semi-structured interviews that scaffolded between their experiences and ways they negotiated and sustained their identities as parents within the context of MFT/FBT for their child. Interview data was analysed through a framework of critical discursive analysis to generate themes centred on these parents' experiences and identity negotiation.

RESULTS

Key findings are that MFT/FBT: (1) provided a map for therapy that initially relieved parents' anxieties for their child and facilitated improvements in family functioning; (2) inadequately addressed parental guilt and blame with a form of externalisation of the illness; (3) perpetuated parental guilt by raising anxiety about AN and allocating responsibility for refeeding their child in phase 1 of the treatment; and (4) when ceased, left these parents struggling with an uncertain future, and fears for the wellbeing of their children.

CONCLUSIONS

The structure of MFT/FBT provided initial relief with some improvements in family communication patterns, however, when the adolescent experienced protracted ED symptoms and/or ongoing psychological distress post-treatment, these parents were left with uncertainty as to how to navigate their shifting roles and their child's ongoing struggles. This research highlights the need for treatments for adolescent AN that more comprehensively address both the adolescent and parents' psychological distress and also (re)build their senses of identity that have been challenged by AN and its effects.

Family therapy approaches for anorexia nervosa

BACKGROUND

Anorexia nervosa (AN) is characterised by a failure to maintain a normal body weight due to a paucity of nutrition, an intense fear of gaining weight or behaviour that prevents the individual from gaining weight, or both. The long-term prognosis is often poor, with severe developmental, medical and psychosocial complications, high rates of relapse and mortality. 'Family therapy approaches' indicate a range of approaches, derived from different theories, that involve the family in treatment. We have included therapies developed on the basis of dominant family systems theories, approaches that are based on or broadly similar to the family-based therapy derived from the Maudsley model, approaches that incorporate a focus on cognitive restructuring, as well as approaches that involve the family without articulation of a theoretical approach.This is an update of a Cochrane Review first published in 2010.

OBJECTIVES

To evaluate the efficacy of family therapy approaches compared with standard treatment and other treatments for AN.

SEARCH METHODS

We searched the Cochrane Common Mental Disorders Controlled Trials Register (CCMDCTR) and PsycINFO (OVID) (all years to April 2016). We ran additional searches directly on Cochrane Central Register for Controlled Trials (CENTRAL), MEDLINE, Ovid Embase, and PsycINFO (to 2008 and 2016 to 2018). We searched the World Health Organization (WHO) trials portal (ICTRP) and ClinicalTrials.gov, together with four theses databases (all years to 2018). We checked the reference lists of all included studies and relevant systematic reviews. We have included in the analyses only studies from searches conducted to April 2016.

SELECTION CRITERIA

Randomised controlled trials (RCTs) of family therapy approaches compared to any other intervention or other types of family therapy approaches were eligible for inclusion. We included participants of any age or gender with a primary clinical diagnosis of anorexia nervosa.

DATA COLLECTION AND ANALYSIS

Four review authors selected the studies, assessed quality and extracted data. We used a random-effects meta-analysis. We used the risk ratio (with a 95% confidence interval) to summarise dichotomous outcomes and both the standardised mean difference and the mean difference to summarise continuous measures.

MAIN RESULTS

We included 25 trials in this version of the review (13 from the original 2010 review and 12 newly-included studies). Sixteen trials were of adolescents, eight trials of adults (seven of these in young adults aged up to 26 years) and one trial included three age groups: one adolescent, one young adult and one adult. Most investigated family-based therapy or variants. Reporting of trial conduct was generally inadequate, so that in a large number of studies we rated the risk of bias as unclear for many of the domains. Selective reporting bias was particularly problematic, with 68% of studies rated at high risk of bias in this area, followed by incomplete outcome data, with 44% of studies rated at high risk of bias in this area. For the main outcome measure of remission there was some low-quality evidence (from only two studies, 81 participants) suggesting that family therapy approaches might offer some advantage over treatment as usual on rates of remission, post intervention (risk ratio (RR) 3.50, 95% confidence interval (CI) 1.49 to 8.23; I2 = 0%). However, at follow-up, low-quality evidence from only one study suggested this effect was not maintained. There was very low-quality evidence from only one trial, which means it is difficult to determine whether family therapy approaches offer any advantage over educational interventions for remission (RR 9.00, 95% CI 0.53 to 153.79; 1 study, N = 30). Similarly, there was very low-quality evidence from only five trials for remission post-intervention, again meaning that it is difficult to determine whether there is any advantage of family therapy approaches over psychological interventions (RR 1.22, 95% CI 0.89 to 1.67; participants = 252; studies = 5; I2 = 37%) and at long-term follow-up (RR 1.08, 95% CI 0.91 to 1.28; participants = 200; studies = 4 with 1 of these contributing 3 pairwise comparisons for different age groups; I2 = 0%). There was no indication that the age group had any impact on the overall treatment effect; however, it should be noted that there were very few trials undertaken in adults, with the age range of adult studies included in this analysis from 20 to 27. There was some evidence of a small effect favouring family based therapy compared with other psychological interventions in terms of weight gain post-intervention (standardised mean difference (SMD) 0.32, 95% CI 0.01 to 0.63; participants = 210; studies = 4 with 1 of these contributing 3 pairwise comparisons for different age groups; I2 = 11%) . Overall, there was insufficient evidence to determine whether there were any differences between groups across all comparisons for most of the secondary outcomes (weight, eating disorder psychopathology, dropouts, relapse, or family functioning measures), either at post-intervention or at follow-up.

AUTHORS' CONCLUSIONS

There is a limited amount of low-quality evidence to suggest that family therapy approaches may be effective compared to treatment as usual in the short term. This finding is based on two trials that included only a small number of participants, and both had issues about potential bias. There is insufficient evidence to determine whether there is an advantage of family therapy approaches in people of any age compared to educational interventions (one study, very low quality) or psychological therapies (five studies, very low quality). Most studies contributing to this finding were undertaken in adolescents and youth. There are clear potential impacts on how family therapy approaches might be delivered to different age groups and further work is required to understand what the resulting effects on treatment efficacy might be. There is insufficient evidence to determine whether one type of family therapy approach is more effective than another. The field would benefit from further large, well-conducted trials.

Predictive factors for outcome in adolescents with anorexia nervosa: To what extent does parental Expressed Emotion play a role?

In studies on family therapy in Anorexia Nervosa, family relationships, as assessed by Expressed Emotion, have been associated with outcome. Our aim was to explore the contribution of Expressed Emotion as a predictor of 18-month outcome, above and beyond the usual predictive factors. Sixty adolescent girls suffering from Anorexia Nervosa and their parents were assessed at baseline and 18 months later. Levels of Expressed Emotion were evaluated in both parents with the Five-Minute Speech Sample. After controlling for treatment group and initial clinical status, high maternal Emotional Over-Involvement at baseline was significantly associated with better clinical state. More precisely, high maternal Emotional Over-Involvement was associated with higher nutritional status, lower eating disorder severity and fewer re-hospitalizations 18 months later. No associations were found with paternal levels of Expressed Emotion. Therefore, our study confirmed the importance of taking into account both maternal and paternal Expressed Emotion. Our results also underlined that high maternal Emotional Over-Involvement plays a positive role in the outcome of Anorexia Nervosa and needs to be explored further.

Augmentative Approaches in Family-Based Treatment for Adolescents with Restrictive Eating Disorders: A Systematic Review

OBJECTIVE

To systematically review the literature reporting outcomes of augmentative family-based treatment (FBT) interventions for adolescents with restrictive eating disorders (EDs).

METHOD

Articles were identified through a systematic search of five electronic databases (PsycINFO, MEDLINE, EMBASE, CINAHL, Cochrane Database).

RESULTS

Thirty articles were included, reporting on FBT augmentations featuring adjunctive treatment components, modified treatment structure and/or content with adherence to FBT principles, and adaptations allowing FBT delivery in different settings. All reported significant improvements in weight and/or ED symptoms at end-of-treatment, although few compared augmentative and standard FBT interventions and good quality follow-up data was generally lacking.

CONCLUSIONS

There is early evidence for the effectiveness of augmentative FBT-based approaches in facilitating weight and/or ED symptom improvements for adolescents with restrictive EDs. There remains a lack of robust evidence demonstrating superior effects of such approaches over standard FBT, and further controlled studies are required to expand on the current evidence.

Expressed Emotions and Depressive Symptoms in Caregivers of Adolescents with First-Onset Anorexia Nervosa-A Long-Term Investigation over 2.5 Years

OBJECTIVE

High levels of expressed emotions (EE) and depressive symptoms (DS) are often found in caregivers of patients with anorexia nervosa (AN). Both parameters are considered to influence AN symptoms of the patient.

METHODS

One hundred seventy adolescent women with AN and their caregivers were assessed at admission, discharge, at 1-year and 2.5-year follow up to evaluate AN symptoms of the patient and EE and DS of caregivers.

RESULTS

The EE and DS were elevated at admission and decreased during treatment, criticism (as part of EE) exhibited again at the 2.5-year follow up. Caregivers of more severely ill patients reported significantly greater levels of EE and DS. Mothers were more affected than fathers. EE and DS were interrelated.

CONCLUSION

Caregivers of adolescent AN patients suffer from elevated levels of EE and DS. Further studies are needed to examine whether therapeutic interventions to reduce caregivers' EE and DS might have a positive influence on treatment outcome.

Exploring Types of Family Environments in Youth with Eating Disorders

While many studies have explored the relationship between different eating disorder diagnoses and the familial social environment, current evidence does not support associations between distinct family interaction patterns (e.g. high enmeshment) and particular diagnoses (e.g. anorexia nervosa). The current study seeks to move beyond the current literature to explore whether empirically derived subtypes of family environment are associated with clinical features within a transdiagnostic sample of youth seeking treatment for eating disorders (n = 123). Latent class modelling of the Family Environment Scale identified three classes (i.e. different Family Environment Scale profiles): (1) Control-Oriented; (2) System Maintenance-Oriented; and (3) Conflict-Oriented. Data are presented to characterize the classes (e.g. age, gender, rates of different eating disorders, severity of eating disorder pathology and rates of comorbid disorders). These preliminary results suggest that family interaction types may help personalize treatment for eating disorders and encourage future research to guide such efforts.

Quantifying the dynamics of emotional expressions in family therapy of patients with anorexia nervosa

Emotional interactions have been considered dynamical processes involved in the affective life of humans and their disturbances may induce mental disorders. Most studies of emotional interactions have focused on dyadic behaviors or self-reports of emotional states but neglected the dynamical processes involved in family therapy. The main objective of this study is to quantify the dynamics of emotional expressions and their changes using the family therapy of patients with anorexia nervosa as an example. Nonlinear methods characterize the variability of the dynamics at the level of the whole therapeutic system and reciprocal influence between the participants during family therapy. Results show that the variability of the dynamics is higher at the end of the therapy than at the beginning. The reciprocal influences between therapist and each member of the family and between mother and patient decrease with the course of family therapy. Our results support the development of new interpersonal strategies of emotion regulation during family therapy. The quantification of emotional dynamics can help understanding the emotional processes underlying psychopathology and evaluating quantitatively the changes achieved by the therapeutic intervention.

Family-based treatment of eating disorders in adolescents: current insights

Eating disorders are serious illnesses associated with significant morbidity and mortality. Family-based treatment (FBT) has emerged as an effective intervention for adolescents with anorexia nervosa, and preliminary evidence suggests that it may be efficacious in the treatment of adolescents with bulimia nervosa. Multifamily therapy for anorexia nervosa provides a more intensive experience for families needing additional support. This review outlines the three phases of treatment, key tenets of family-based treatment, and empirical support for FBT. In addition, FBT in higher levels of care is described, as well as challenges in the implementation of FBT and recent adaptations to FBT, including offering additional support to eating-disorder caregivers. Future research is needed to identify families for whom FBT does not work, determine adaptations to FBT that may increase its efficacy, develop ways to improve treatment adherence among clinicians, and find ways to support caregivers better during treatment.

Relational containment: exploring the effect of family-based treatment for anorexia on familial relationships

BACKGROUND

The aim of this research was to investigate the process of familial relationship change for adolescents with anorexia nervosa and their parents, who participated in Family-Based Treatment (FBT).

METHOD

A Constructionist grounded theory design was employed with purposive sampling. Sixteen young people between 12 and 18 years with a good outcome in FBT and twenty-eight of their parents participated. Young people and their parents took part in separate interviews at the end of treatment. Each interview was transcribed and analysed to identify a unifying phenomenon across the data to elicit a theory that explained the data and then integrated into existing theory.

RESULTS

Prior to treatment families' experienced significant conflict, disconnection and isolation. The FBT structure, therapist direction, and the specialist medical setting created a process of relational containment. This enabled parents to trust the process of FBT and develop confidence in their executive role in the family. In turn this allowed the adolescent with anorexia nervosa to trust their parents, feel more secure and gradually engage in the treatment process themselves. Improvements in closeness, communication and adolescent sense of self were reported after FBT.

CONCLUSIONS

These findings illuminate a possible mechanism of change in FBT. It underscores the importance of parental management of eating disorder symptoms at the commencement of treatment to enable increased parental confidence. Meaningful changes occurred for the adolescents' that aided normal developmental and relational processes, an important aspect of recovery.

How does family functioning effect the outcome of family based treatment for adolescents with severe anorexia nervosa?

BACKGROUND

The aim of this research was to investigate the relationship between family functioning, adolescent-parent attachment and remission, as well as changes in these variables over time for adolescents with severe anorexia nervosa treated with family based treatment (FBT). Understanding how families respond to treatment is important because the family will be the ongoing context for psychosocial development in the longer term. The relationship between family functioning and outcome is also an important variable because it is potentially modifiable during treatment and this may improve outcome.

METHODS

Fifty-seven female adolescents treated with FBT in a randomised controlled trial were assessed at baseline, FBT session 20 and 12-months post FBT session 20. Data on family functioning and adolescent-parent attachment was collected from patients and their parents at each time point. A series of regression analyses were used to determine the relationship between family functioning and comorbidity at baseline, and the relationship with remission status over time. Repeat measure mixed-effects models were used to assess changes in family functioning and attachment quality over time.

RESULTS

Greater adolescent perceived family functioning impairment was positively related to psychiatric comorbidity at the start of treatment. Conversely, better family functioning predicted higher self-esteem and stronger attachment quality. Adolescent's reporting better general family functioning, communication and problem solving were more likely to be remitted at session 20, but not at 12-month follow-up. There was no overall improvement in family functioning for any respondent either during treatment or at follow-up, and no significant relationship between change and remission at either session 20 or follow-up.

CONCLUSIONS

The adolescent's perspective on family functioning at the start of treatment impacts on a positive outcome. Addressing family issues earlier in FBT may be important for some patients. Further research is needed in this area to determine how these findings could be integrated into the current FBT model.

Change in expressed emotion and treatment outcome in adolescent anorexia nervosa

Expressed emotion (EE) has been associated with poor outcomes in anorexia nervosa (AN); however, whether changes in EE predict superior treatment outcomes is unknown. The current study examined whether decreases in EE during an open trial of a novel family-based treatment for AN predicted symptoms at end of treatment. Forty-seven adolescents (12-18 years of age) with AN or sub-threshold AN and their parents (mothers: n = 47, fathers: n = 39) participated in 6 months of family treatment. Measures of AN symptomatology (Eating Disorder Examination completed by adolescent and end of treatment recovery status) and parental EE (Family Questionnaire completed by parents which measures two facets of EE: critical communication [CC] and emotional over-involvement [EOI]) were collected at baseline and end of treatment. Parental EOI, but not CC, significantly decreased during the course of treatment. Change in mothers', but not fathers', EE accounted for additional variance in AN symptomatology at end of treatment above baseline EE and baseline AN symptom levels. Findings suggest a greater emphasis on parent support during treatment may improve outcomes.

Patterns of expressed emotion in adolescent eating disorders

BACKGROUND

This goal of this study was to understand the patterns of expressed emotions (EEs) in adolescent eating disorders. As such, this study compared EE among families of adolescents with anorexia nervosa (AN), bulimia nervosa (BN), and a psychiatric control group, major depressive disorder (MDD). This study also examined the influence of family status (intact vs. nonintact) and the presence of siblings on EE.

METHODS

Two-hundred and fifteen adolescents (ages 12-19) and their families were recruited for this study including 121 adolescents with AN, 54 adolescents with BN, and 40 adolescents with MDD. Adolescents with at least one parent completed the Standardized Clinical Family Interview. Adolescents completed structured diagnostic interviews to assess eligibility for the study, as well as a standardized questionnaire to assess depression.

RESULTS

Analyses revealed that fathers showed higher levels of critical comments to adolescents with BN or MDD than those with AN, whereas mothers made more critical comments toward patients with BN. Mothers made the least number of positive remarks toward patients with MDD. In terms of the influence of family status, fathers from intact families showed more expressions of warmth and were less critical than fathers from nonintact families, whereas mothers from intact families were less critical but also made fewer positive remarks than mothers from nonintact families. The presence of siblings appeared to reduce mothers' expression of warmth and emotional overinvolvement.

CONCLUSIONS

Unique patterns of EE were found to characterize AN, BN, and MDD. Family status and the presence of siblings exert an influence on EE that should be taken into consideration in future research.

Therapeutic alliance, expressed emotion, and treatment outcome for anorexia nervosa in a family-based partial hospitalization program

Adolescent therapeutic alliance has been found to be associated with improvements in eating disorder cognitions and with early weight gain. The current study assessed patient and parent therapeutic alliance, correlates of parent alliance, and relationship between alliance and treatment outcome. Fifty-six patients with anorexia nervosa completed measures of therapeutic alliance and eating disorder symptoms. Patients' parents completed measures of therapeutic alliance, expressed emotion, and psychopathology. Patients' alliance predicted cognitive and behavioral symptomatology at end of treatment (β=-0.39, p=0.001), though it was not related to changes in weight (β=0.12, p=0.377). Maternal hostility was associated with lower maternal alliance (r=-0.34, p=0.05). Findings suggest that maternal hostility should be addressed in treatment, and that patient alliance may be important in achieving psychological recovery from disordered eating.

Perceived Expressed Emotion in Adolescents with Binge-Eating Disorder

A sizeable body of research has documented Expressed Emotion (EE) to predict clinical outcomes in various psychiatric disorders, including eating disorders. Patients' perceptions of relative's EE, however, were found to play an important role in the processing of EE. This study aimed to examine the level of perceived EE in adolescent binge-eating disorder (BED) and its impact on eating disorder psychopathology. Adolescents (12-20 years) seeking treatment for BED (n = 40) were compared to adolescents without current or lifetime eating disorder (CG; n = 40). Both groups were stratified according to age, sex, body mass index (BMI, kg/m(2)), and socio-economic status. The Five Minute Speech Sample (FMSS) and the Brief Dyadic Scale of EE were administered to assess patients' perceived maternal EE. Additionally, adolescents and mothers completed questionnaires on eating disorder and general psychopathology. On the FMSS, 37.5 % of patients with BED perceived their mothers as high EE (vs. 12.5 % in the CG). On the Brief Dyadic Scale of EE, patients with BED reported significantly higher levels of perceived maternal criticism, emotional overinvolvement, and lower levels of perceived warmth than controls. After controlling for the diagnosis of BED, perceived criticism and warmth, as assessed by questionnaire, significantly explained adolescents' global eating disorder psychopathology. Negative perceptions of maternal behavior and emotional atmosphere towards the child are characteristic of adolescent BED. As documented for other eating disorders, family factors are likely to have substantial implications for the maintenance and treatment of adolescent BED.

Validity of the Brief Dyadic Scale of Expressed Emotion in Adolescents

PURPOSE

Perceived expressed emotion is a valuable predictor of clinical outcome in psychiatric and community samples, but its assessment is limited to few instruments. A recent development to briefly assess expressed emotion from the patient's perspective is the 14-item Brief Dyadic Scale of Expressed Emotion (BDSEE). Although psychometric properties of the BDSEE have been provided for adult eating disorders, validity for adolescents is still lacking. In this study, BDSEE's factorial, convergent, and divergent validity was tested in an adolescent sample with binge-eating disorder and a matched community sample.

METHODS

For validation, well-established self- and mother-report questionnaires and adolescent's Five Minute Speech Sample were used.

RESULTS

Confirmatory factor analysis on the German BDSEE replicated the proposed three-factor structure in adolescents. BDSEE's convergent validity with the Five Minute Speech Sample and construct-related questionnaires was shown. Divergent validity was documented with BDSEE subscales being unrelated to socio-demographic and clinical characteristics. Further, BDSEE subscales were unrelated to measures of maternal distress.

CONCLUSIONS

While the results underline that the BDSEE is a valid self-report measure for assessing perceived expressed emotion in adolescents with and without binge-eating disorder, the evaluation of its predictive validity is still in need.

Predictors of treatment outcome in individuals with eating disorders: A systematic review and meta-analysis

OBJECTIVE

Understanding the factors that predict a favourable outcome following specialist treatment for an eating disorder may assist in improving treatment efficacy, and in developing novel interventions. This review and meta-analysis examined predictors of treatment outcome and drop-out.

METHOD

A literature search was conducted to identify research investigating predictors of outcome in individuals treated for an eating disorder. We organized predictors first by statistical type (simple, meditational, and moderational), and then by category. Average weighted mean effect sizes (r) were calculated for each category of predictor.

RESULTS

The most robust predictor of outcome at both end of treatment (EoT) and follow-up was the meditational mechanism of greater symptom change early during treatment. Simple baseline predictors associated with better outcomes at both EoT and follow-up included higher BMI, fewer binge/purge behaviors, greater motivation to recover, lower depression, lower shape/weight concern, fewer comorbidities, better interpersonal functioning and fewer familial problems. Drop-out was predicted by more binge/purge behaviors and lower motivation to recover. For most predictors, there was large interstudy variability in effect sizes, and outcomes were operationalized in different ways. There were generally insufficient studies to allow analysis of predictors by eating disorder subtype or treatment type.

DISCUSSION

To ensure that this area continues to develop with robust and clinically relevant findings, future studies should adopt a consistent definition of outcome and continue to examine complex multivariate predictor models. Growth in this area will allow for stronger conclusions to be drawn about the prediction of outcome for specific diagnoses and treatment types.

Expressed Emotion, Family Functioning, and Treatment Outcome for Adolescents with Anorexia Nervosa

The current study examined the relation between parental expressed emotion (EE) and treatment outcome among adolescents participating in a treatment study for adolescent anorexia nervosa, as well as its impact on family functioning. One hundred and twenty-one families were assigned to family-based treatment or adolescent-focused therapy. Paternal criticism predicted lesser improvement in eating disorder psychopathology at end of treatment. There was also a significant interaction between maternal hostility and treatment, indicating that adolescents whose mothers displayed hostility had greater increases in percent of expected body weight in adolescent-focused therapy than family-based treatment. In addition, maternal hostility predicted less improvement in general family functioning and family communication at the end of treatment. Findings suggest that maternal and paternal EE may differentially impact treatment outcome and should be directly attended to in clinical settings. Future research is needed to further explore ways in which parental EE can be effectively modified in treatment.

Family-based Treatment of Child and Adolescent Eating Disorders

Best-practice guidelines for the treatment of child and adolescent eating disorders recommend the inclusion of parents. Family-based treatment (FBT) posits that families are not only important in supporting their children but are critical change agents in the recovery process. As originally developed for anorexia nervosa, parents take a central role in managing and disrupting eating disorder symptoms. The most evidence-based treatment model for adolescent anorexia nervosa, FBT has also recently been found to be useful in the treatment of adolescent bulimia nervosa. This article provides a summary of the theoretic model, evidence base, and application of FBT.

Family Profiles of Expressed Emotion in Adolescent Patients With Anorexia Nervosa and Their Parents

The current study examined expressed emotion (EE) among families of adolescents with anorexia nervosa (AN) participating in a treatment study. EE ratings were made from 110 adolescents toward their parents and from parents toward their children using videotaped family interviews. Participants were 92% female and 75% Caucasian with a mean age of 14.41 years. Four family profiles were created (low patient EE/low parent EE, high patient EE/high parent EE, low patient EE/high parent EE, high patient EE/low parent EE). Family EE profile was not related to full remission at end of treatment. Groups were then combined according to EE level of parent. The low parent group (defined as low on criticism, hostility, and emotional overinvolvement) had significantly lower scores on a measure of eating disorder psychopathology than the high parent group at the end of treatment. Patients with AN in low EE families do better in treatment than those patients belonging to high EE families. These findings are true regardless of the EE status of the patient.

A bidirectional examination of expressed emotion among families of adolescents with bulimia nervosa

OBJECTIVE

The purpose of this paper was to examine expressed emotion (EE) measured from adolescents with bulimia nervosa (BN) toward their parents, in addition to measuring EE from parents toward patients.

METHOD

Fifty-four adolescents and their parents who were receiving treatment for BN participated in a videotaped family interview, from which ratings of EE were made.

RESULTS

Parent and patient scores were highly correlated. Four family profiles were created (Low Patient EE/Low Parent EE; High Patient EE/High Parent EE; Low Patient EE/High Parent EE; High Patient EE/Low Parent EE) to determine whether the match between parent and patient EE was related to treatment outcome. The Low Patient EE/Low Parent EE group demonstrated the greatest reduction in purging from baseline to end-of-treatment; the High Patient EE/Low Parent EE group showed the smallest reduction in purging.

DISCUSSION

EE has historically been rated from relatives toward patients, but patients' own EE may also be related to treatment outcome.

Development and evaluation of a treatment fidelity instrument for family-based treatment of adolescent anorexia nervosa

OBJECTIVE

This study provides data on the psychometric properties of a newly developed measure of treatment fidelity in Family-Based Treatment (FBT) for adolescent anorexia nervosa (AN). The Family Therapy Fidelity and Adherence Check (FBT-FACT) was created to evaluate therapist adherence and competency on the core interventions in FBT.

METHOD

Participants were 45 adolescents and their families sampled from three randomized clinical trials evaluating treatment for AN. Trained fidelity raters evaluated 19 therapists across 90 early session recordings using the FBT-FACT. They also rated an additional 15 session 1 recordings of an alternate form of family therapy-Systemic Family Therapy for the purpose of evaluating discriminant validity of the FBT-FACT. The process of development and the psychometric properties of the FBT-FACT are presented.

RESULTS

Overall fidelity ratings for each session demonstrated moderate to strong inter-rater agreement. Internal consistency of the measure was strong for sessions 1 and 2 and poor for session 3. Principal components analysis suggests sessions 1 and 2 are distinct interventions.

DISCUSSION

The FBT-FACT demonstrates good reliability and validity as a measure of treatment fidelity in the early phase of FBT.

A systematic review of family caregiving in eating disorders

The objective of the study was to review systematically the available new evidence on family caregiving in eating disorders (ED), updating the study of Zabala, Macdonald, and Treasure (2009). Electronic databases were searched from October 2008 until May 2013. Selected studies included carers of people with ED and employed one or more measures of caregiving experience, accommodation and enabling behaviours, expressed emotion, and/or psychological distress. Twenty-nine studies were identified. Most of the studies examined these features in mothers of patients with anorexia. Only a few studies included a control group. The majority of studies found high levels of negative aspects of caregiving, accommodation and enabling behaviours, expressed emotion and psychological distress in carers of people with ED, although positive aspects and emotions were also reported. These features varied depending on some sociodemographic and clinical characteristics of carers and patients; moreover, interesting preliminary cultural and gender differences emerged. Progress has been made in research on family caregiving in ED and there is evidence that these factors can be associated with the outcome of ED. Theoretical, research and clinical implications of the findings are discussed.

Expressed emotion in anorexia nervosa: what is inside the "black box"?

OBJECTIVE

Expressed Emotion has been called a "black box", since little is known about contributing factors. The aim of this study was to examine which parental and which patient/illness-related characteristics contribute to maternal and paternal Expressed Emotion levels.

METHOD

Sixty adolescent girls with Anorexia Nervosa (AN) and their parents completed instruments that evaluate characteristics of the adolescent's illness and patient/parental psychological characteristics (depression; anxiety; obsession-compulsion; social anxiety and alexithymia). The following illness-related characteristics were recorded: age at AN onset, duration of illness, AN subtype (restrictive AN-R vs. purging type AN-B), current Body Mass Index (BMI) (in kg/m(2)), minimum lifetime BMI and number of previous hospitalizations, the Global Outcome Assessment Scale total score. Levels of Expressed Emotion were assessed for the two parents using the Five-Minute Speech Sample.

RESULTS

Less than 30% of the parents in our sample expressed high levels of Critical EE and Emotional Over-Involvement. Our main findings indicate that maternal Criticism (Critical EE levels, Critical Comments, Dissatisfaction) and the sub-dimensions of maternal Emotional Over-Involvement (EOI EE) (Statement of loving Attitudes and Excessive Details about the past) were related both to the severity of the daughters' clinical state and to maternal psychological functioning. Only paternal levels of anxiety explained paternal Dissatisfaction, EOI EE and Statement of loving Attitudes.

DISCUSSION

Parental psychological functioning and the severity of the daughters' clinical state have an impact on the family relationships. These elements should be targeted by individual treatment for parents where necessary, and by psycho-educational sessions about Anorexia Nervosa for parents generally.

A multi-centre cohort study of short term outcomes of hospital treatment for anorexia nervosa in the UK

BACKGROUND

Individual, family and service level characteristics and outcomes are described for adult and adolescent patients receiving specialist inpatient or day patient treatment for anorexia nervosa (AN). Potential predictors of treatment outcome are explored.

METHOD

Admission and discharge data were collected from patients admitted at 14 UK hospital treatment units for AN over a period of three years (adult units N = 12; adolescent N = 2) (patients N = 177).

RESULTS

One hundred and seventy-seven patients with a severe and enduring illness with wide functional impairment took part in the study. Following inpatient care, physical improvement was moderate/good with a large increase in BMI, although most patients continued to have a clinical level of eating disorder symptoms at discharge. The potentially modifiable predictors of outcome included confidence to change, social functioning and carer expressed emotion and control.

CONCLUSIONS

Overall, the response to inpatient treatment was modest particularly in the group with a severe enduring form of illness. Adolescents had a better response. Although inpatient treatment produces an improvement in physical health there was less improvement in other eating disorder and mood symptoms. As predicted by the carer interpersonal maintenance model, carer behaviour may influence the response to inpatient care, as may improved social functioning and confidence to change.

A Pilot Study of an Acceptance-Based Separated Family Treatment for Adolescent Anorexia Nervosa

The treatment of adolescent anorexia nervosa (AN) has improved significantly with the increased emphasis on family-based intervention. Yet despite advances, a substantial number of adolescents do not respond optimally to existing treatment models and thus there is a need for treatment alternatives that address barriers to recovery. We developed and piloted an acceptance-based separated family treatment (ASFT) with 6 adolescents with AN or subthreshold AN (eating disorder not otherwise specified, with the primary symptoms of restriction and severe weight loss). Treatment acceptability was adequate. Overall, parents rated the treatment as credible and expected improvement in their child's condition. Five of the 6 adolescents treated with ASFT restored weight to their ideal body mass index as indicated by age, height, and sex and determined by individual growth charts. Many demonstrated improved psychological health and adaptive functioning. There was evidence of broad effects, with parents reporting decreased anxiety and caregiver burden. ASFT holds promise as a treatment option for AN. The efficacy of this therapeutic approach should be tested in larger trials and compared to current family-based interventions to determine unique effects.

Do in-vivo behaviors predict early response in family-based treatment for anorexia nervosa?

The aim of the study is to explore whether identified parental and patient behaviors observed in the first few sessions of family-based treatment (FBT) predict early response (weight gain of 1.8 kg by session four) to treatment. Therapy film recordings from 21 adolescent participants recruited into the FBT arm of a multi-site randomized clinical trial were coded for the presence of behaviors (length of observed behavior divided by length of session recording) in the first, second and fourth sessions. Behaviors that differed between early responders and non-early responders on univariate analysis were entered into discriminant class analyses. Participants with fewer negative verbal behaviors in the first session and were away from table during the meal session less had the greatest rates of early response. Parents who made fewer critical statements and who did not repeatedly present food during the meal session had children who had the greatest rates of early response. In-vivo behaviors in early sessions of FBT may predict early response to FBT. Adaptations to address participant resistance and to decrease the numbers of critical comments made by parents while encouraging their children to eat might improve early response to FBT.

The need for complex ideas in anorexia nervosa: why biology, environment, and psyche all matter, why therapists make mistakes, and why clinical benchmarks are needed for managing weight correction

Anorexia nervosa remains an enigma and its clinical challenge is intimidating. But the potential for new insights has been advancing, largely as a result of elegant research in the neurosciences that has modeled behavioral processes resembling key features of the illness. Unfortunately, many in the eating disorder field seem to know little of this work or the implication it holds for treatment philosophy. Instead, the knowledge void has been taken up recently by a host of misguided notions about etiology, blatantly dismissive attitudes toward psychological concepts, and ill-conceived beliefs about therapy priorities. This article is a clinical perspective on these issues.

Cultural variability in Expressed Emotion among families of adolescents with anorexia nervosa

OBJECTIVE

To examine the cultural variability in Expressed Emotion (EE) among families of white and ethnic minority adolescents with anorexia nervosa (AN).

METHOD

One-hundred and eighty-nine AN patients and their parents completed the Eating Disorder Examination and the Structured Clinical Family Interview, from which EE ratings were made.

RESULTS

No differences were found in the number of white and minority families classified as high EE. White families were higher on warmth (W) and tended to be higher on positive remarks (PR) than minority families. High EE was associated with a longer duration of illness, but was not related to eating disorder pathology.

DISCUSSION

Few differences were found between white and ethnic minority families on the EE dimensions of CC, hostility (H), or EOI. Differences between families on W and PR, however, may have important treatment implications.
