RESUMO
OBJECTIVE: Previous studies have indicated that virtual treatments for eating disorders (EDs) are roughly as effective as are in-person treatments; the present nonrandomized study aimed to expand on the current body of evidence by comparing outcomes from a virtual day treatment program with those of an in-person program in an adult ED sample. METHOD: Participants were 109 patients who completed at least 60% of day treatment sessions (n = 55 in-person and n = 54 virtual). Outcome measures included ED and comorbid symptoms, and motivation. RESULTS: Linear mixed models showed that global EDE-Q scores decreased during treatment (AIC = 376.396, F = 10.94, p = 0.002), irrespective of treatment modality (p = 0.186). BMI significantly increased over time (AIC = 389.029, F = 27.97, p < 0.001), with no effect of treatment modality (p = 0.779). DISCUSSION: Our findings suggest that the virtual delivery of day treatments produces comparable outcomes to those obtained using in-person formats, and that virtual formats may represent a pragmatic treatment option, especially in situations in which access to in-person care is limited.
RESUMO
BACKGROUND: Given limited availability of informed treatments for people affected by eating disorders (EDs), there has been increasing interest in developing self-administered, technology-based ED interventions. However, many available interventions are limited to a specific ED diagnosis or assume that participants are ready to change. We developed a digital self-help application (called ASTrA) that was explicitly designed to be transdiagnostic and to help increase motivation for change. The aim of the present study was to describe the development and examine the psychometric properties, user satisfaction and rated potentials for practical use of our application. METHODS: The content of our application was based on concepts derived from self-determination theory, the transtheoretical model of change, and cognitive theory. The application was developed by a multidisciplinary team of clinicians, researchers, staff members and individuals with lived ED experience, each being involved in all steps of the application's development. We tested validity, reliability, satisfaction and perceived feasibility for clinical implementation in an independent sample of 15 patients with an ED and 13 clinicians specialized in ED treatment. Psychometric properties were evaluated using descriptive statistics, correlations, content validity indices and intraclass coefficients. Differences in satisfaction ratings and perceived potential for clinical implementation of the application between clinicians and patients were examined using Mann-Whitney U tests. RESULTS: The digital application showed excellent validity (mean i-CVI: .93, range: .86-.96) and internal reliability (all Cronbach alpha's > .88). Patients and clinicians both considered the application acceptable, appropriate, and feasible for use in clinical practice. CONCLUSIONS: Findings suggest that our transdiagnostic interactive application has excellent psychometric properties. Furthermore, patients and clinicians alike were positive about the possible use of the application in clinical practice. The next step will be to investigate the application's effectiveness as an intervention to promote autonomous motivation and to facilitate remission in people on the waitlist for specialized ED treatment.
RESUMO
OBJECTIVE: To determine the association between adolescent hospitalization for suicide attempts and the subsequent risk of eating disorder hospitalization. METHOD: This was a cohort study of 162,398 adolescent girls in Quebec, Canada, including 7741 with suicide attempts before 20 years of age, matched to 154,657 adolescents with no attempt between 1989 and 2019. The main exposure measure was suicide attempt hospitalization. The main outcome measure was hospitalization for an eating disorder up to 31 years later, including anorexia nervosa, bulimia nervosa, and other eating disorders. We used adjusted Cox regression models to estimate hazard ratios (HR) and 95% confidence intervals (CI) for the association between adolescent suicide attempts and eating disorder hospitalization. RESULTS: Adolescent girls admitted for a suicide attempt had 5.55 times the risk of eating disorder hospitalization over time (95% CI 3.74-8.23), compared with matched controls. Suicide attempt was associated with anorexia nervosa (HR 3.57, 95% CI 1.78-7.17) and bulimia nervosa and other eating disorders (HR 8.55, 95% CI 5.48-13.32). Associations were pronounced in girls with repeated suicide attempts. Girls who attempted suicide through self-poisoning had an elevated risk of anorexia nervosa, whereas girls who used violent methods such as cutting or piercing had a greater risk of bulimia nervosa and other eating disorders. Suicide attempt was strongly associated with eating disorder hospitalization in the year following the attempt, but associations persisted throughout follow-up. DISCUSSION: Suicide attempt admission is associated with the long-term risk of eating disorder hospitalization in adolescent girls. PUBLIC SIGNIFICANCE: This study of adolescent girls suggests that suicide attempt admission is associated with the long-term risk of hospitalization for eating disorders. The risk is greatest in the year after the attempt, but persists over time. Adolescents who present with a suicide attempt may benefit from screening for eating disorders and long-term follow-up to help prevent the exacerbation or development of eating disorders.

BACKGROUND: We studied the effect of the Covid-19 pandemic on child eating disorder hospitalizations in Quebec, Canada. Quebec had one of the strictest lockdown measures targeting young people in North America. METHODS: We analyzed eating disorder hospitalizations in children aged 10-19 years before and during the pandemic. We used interrupted time series regression to assess trends in the monthly number of hospitalizations for anorexia nervosa, bulimia nervosa, and other eating disorders before the pandemic (April 2006 to February 2020), and during the first (March to August 2020) and second waves (September 2020 to March 2021). We determined the types of eating disorders requiring hospital treatment and identified the age, sex and socioeconomic subgroups that were most affected. RESULTS: Hospitalization rates for eating disorders increased during the first (6.5 per 10,000) and second waves (12.8 per 10,000) compared with the period before the pandemic (5.8 per 10,000). The increase occurred for anorexia nervosa as well as other types of eating disorders. The number of girls and boys aged 10-14 years admitted for eating disorders increased during wave 1. Wave 2 triggered an increase in eating disorder admissions among girls aged 15-19 years. Hospitalization rates increased earlier for advantaged than disadvantaged youth. CONCLUSIONS: The Covid-19 pandemic affected hospitalizations for anorexia nervosa as well as other eating disorders, beginning with girls aged 10-14 years during wave 1, followed by girls aged 15-19 years during wave 2. Boys aged 10-14 years were also affected, as well as both advantaged and disadvantaged youth.

PURPOSE: To determine if suicide attempts increased during the first year of the pandemic among young adolescents in Quebec, Canada. METHODS: We analyzed children aged 10-14 years who were hospitalized for a suicide attempt between January 2000 and March 2021. We calculated age-specific and sex-specific suicide attempt rates and the proportion of hospitalizations for suicide attempts before and during the pandemic and compared rates with patients aged 15-19 years. We used interrupted time series regression to measure changes in rates during the first (March 2020 to August 2020) and second (September 2020 to March 2021) waves and difference-in-difference analysis to determine if the pandemic had a greater impact on girls than boys. RESULTS: Suicide attempt rates decreased for children aged 10-14 years during the first wave. However, rates increased sharply during the second wave for girls, without changing for boys. Girls aged 10-14 years had an excess of 5.1 suicide attempts per 10,000 at the start of wave 2, with rates continuing to increase by 0.6 per 10,000 every month thereafter. Compared with the prepandemic period, the increase in the proportion of girls aged 10-14 years hospitalized for a suicide attempt was 2.2% greater than that of boys during wave 2. The pattern seen in girls aged 10-14 years was not present in girls aged 15-19 years. DISCUSSION: Hospitalizations for suicide attempts among girls aged 10-14 years increased considerably during the second wave of the pandemic, compared with boys and older girls. Young adolescent girls may benefit from screening and targeted interventions to address suicidal behavior.

OBJECTIVES: Recent studies have reported altered methylation levels at disorder-relevant DNA sites in people who are ill with Anorexia Nervosa (AN) compared to findings in people with no eating disorder (ED) or in whom AN has remitted. The preceding implies state-related influences upon gene expression in people with AN. This study further examined this notion. METHODS: We measured genome-wide DNA methylation in 145 women with active AN, 49 showing stable one-year remission of AN, and 64 with no ED. RESULTS: Comparisons revealed 205 differentially methylated sites between active and no ED groups, and 162 differentially methylated sites between active and remitted groups (Q < 0.01). Probes tended to map onto genes relevant to psychiatric, metabolic and immune functions. Notably, several of the genes identified here as being differentially methylated in people with AN (e.g. SYNJ2, PRKAG2, STAT3, CSGALNACT1, NEGR1, NR1H3) have figured in previous studies on AN. Effects also associated illness chronicity and lower BMI with more pronounced DNA methylation alterations, and remission of AN with normalisation of DNA methylation. CONCLUSIONS: Findings corroborate earlier results suggesting reversible DNA methylation alterations in AN, and point to particular genes at which epigenetic mechanisms may act to shape AN phenomenology.

Despite availability of evidence-based treatments for eating disorders (EDs), individuals with EDs often do not receive informed treatment. Training of non-specialized clinicians by experienced professionals through knowledge exchange (KE) programs is an effective way to enhance accessibility to evidence-based treatments for EDs. The authors conducted a qualitative analysis of factors that facilitated or impeded the uptake of an ED-focused KE program. Semi-structured interviews were conducted with mental health professionals (n = 43) and managers (n = 11) at 13 community mental-health sites at which the KE program was offered. Data were analyzed using a qualitative content analysis. Key facilitators identified were management support for the program and building competence through ongoing supervision of clinicians. Main barriers were limited access to ED patients to treat and having insufficient time to apply ED interventions in front-line settings. The results provide insights into the practical imperatives involved in implementing a KE initiative for ED treatment.

PURPOSE: Self-determination theory suggests that autonomous motivation for change (i.e., motivation that is internal and self-endorsed) can be enhanced in therapeutic contexts by clinicians acting in an autonomy supportive manner. While previous research has established a link between autonomy support (AS) and autonomous motivation in enhancing outcomes in eating disorder (ED) treatment, few studies have examined factors that support or hinder therapists' ability to be autonomy supportive in the context of an ED therapeutic encounter. The goal of the present study was to conduct a qualitative analysis of personal and contextual factors that facilitated or hindered therapists' ability to provide autonomy supportive interventions. METHODS: Semi-structured interviews were conducted with 10 therapists conducting outpatient psychotherapy at a specialized eating disorders treatment program. Data were analyzed using thematic analysis. RESULTS: The most frequently noted facilitators were organizational support of AS interventions and patients' engagement and motivation for treatment. The most frequently noted barriers were patients' personality variables such as patients that exhibit passive and help-rejecting behaviours, as well as therapists feeling overwhelmed due to a high workload. CONCLUSION: Our results provide insight into the factors that facilitate and impede the utilization of an autonomy supportive approach in specialized ED treatment and can be used to inform future quantitative research on such factors. LEVEL OF EVIDENCE: Level V: Opinions of respected authorities, based on descriptive studies, narrative reviews, clinical experience, or reports of expert committees.

OBJECTIVE: Findings show virtual therapy (conducted using internet-based videoconferencing techniques) to be a viable alternative to in-person therapy for a variety of mental-health problems. COVID-19 social-distancing imperatives required us to substitute virtual interventions for in-person sessions routinely offered in our outpatient eating disorder (ED) program-and afforded us an opportunity to compare the two treatment formats for clinical efficacy. METHODS: Using self-report assessments, we compared outcomes in a historical sample of 49 adults with heterogeneous EDs (treated in-person over 10-14 weeks in individual and group therapies) to those of 76 patients receiving comparable virtual treatments, at distance, during the COVID-19 outbreak. Linear mixed models were used to study symptom changes over time and to test for differential effects of treatment modality. RESULTS: Participants in both groups showed similar improvements on eating symptoms, levels of weight gain (in individuals in whom gain was indicated), and satisfaction with services. DISCUSSION: Our results suggest that short-term clinical outcomes with virtual and in-person ED therapies are comparable, and point to potentials of virtual therapy for situations in which geographical distance or other barriers impede physical access to trained therapists or specialized treatments.

Although treatment dropout is common among patients with eating disorders, very few studies have examined predictors of non-completion in day treatment. We investigated various potential predictors of dropout from adult day treatment. Participants were 295 adult patients with a diagnosis of Anorexia Nervosa (restricting or binge-eating/purging subtype), Bulimia Nervosa (BN), Other Specified Feeding or Eating Disorder, or Avoidant Restrictive Food Intake Disorder. Predictors included eating-disorder characteristics, motivation at the commencement of treatment, Body Mass Index (BMI), time spent in treatment and personality dimensions. Logistic regression analyses showed that for patients with a BMI of less than 20 at the start of treatment, low BMI was a significant predictor of staff-initiated termination due to not meeting weight gain goals. Furthermore, completing less than 6 weeks of treatment was associated with staff-initiated termination. For the whole sample, those with higher changes in weight over the course of treatment were less likely to terminate prematurely. None of the other predictor variables yielded significant results. Results of the current study highlight characteristics of patients who are more likely not to complete day treatment and can help identify patients who may be at risk for not succeeding in multi-diagnostic day treatment programs.

OBJECTIVE: Identifying modifiable predictors of outcomes following treatment for eating disorders may help to tailor interventions to patients' individual needs, improve treatment efficacy, and develop new interventions. The goal of this meta-analysis was to quantify the association between pretreatment motivation and posttreatment changes in eating disorder symptomology. METHOD: We reviewed 196 longitudinal studies reporting on change on indices of overall eating-disorder symptomatology, weight gain, binge-eating, vomiting, anxiety/depression, and treatment adherence. Meta-analyses were performed using two complementary approaches: (a) combined probability analysis using the added Z's method; (b) effect size analyses. Using random-effect models, effect sizes were pooled when there were at least three studies with the same type of statistical design and reporting statistics on the same outcome. Heterogeneity in study outcome was evaluated using Q and I2 statistics. Studies were reviewed qualitatively when the number of studies or reported data were insufficient to perform a meta-analysis. RESULTS: Forty-two articles were included. Although samples and treatments differed substantially across studies, results across studies were remarkably consistent. Both combined-probability and effect-size analyses indicated positive effects of pretreatment motivation on improvement in general eating-disorder symptoms (Cohen's r = .17), and an absence of effects on anxiety/depression symptoms. Remaining outcome indices were subject to selective reporting and/or small sample size bias. DISCUSSION: Our findings underscore the importance of incorporating treatment engagement approaches in the treatment of eating disorders. Optimal reporting of study findings and improving study quality would improve future efforts to obtain an in-depth understanding of the relationship between motivation and eating disorder symptoms.

OBJECTIVE: People who are ill with anorexia nervosa (AN) show altered availability of key plasma nutrients. However, little is known about the patterning of alterations that occurs across diverse nutrients during active phases of illness or about the persistence of any such alterations following remission of illness. METHOD: We compared plasma levels of one-carbon metabolism nutrients across women with active AN (AN-Active: n = 53), in remission from AN (AN-Remitted: n = 40), or who had no eating-disorder history (NED: n = 36). We also tested associations between body mass index (BMI) changes and changes in pre- to posttreatment nutrient levels, and explored the association between nutrient levels, on the one hand, and BMI and eating symptoms, on the other. Choline, betaine, and methionine were analyzed using mass spectrometry. Folate and B12 were analyzed using the AccuBind® ELISA kit. Eating-disorder symptoms were assessed by interview and self-report. RESULTS: Compared to NED individuals, AN-Active individuals exhibited significantly elevated B12 and (less-reliably) betaine. In AN-Active individuals, lower BMI was associated with higher B12. DISCUSSION: The observed alterations run contrary to the intuition that plasma nutrient levels should be directly responsive to nutritional status and suggest, instead, the existence of compensatory adaptations to malnutrition in individuals with active AN. Further study is required to clarify mechanisms that underlie such effects.

DNA methylation allows for the environmental regulation of gene expression and is believed to link environmental stressors to psychiatric disorder phenotypes, such as anorexia nervosa (AN). The oxytocin receptor (OXTR) gene is epigenetically regulated, and studies have shown associations between OXTR and social behaviours in various samples, including women with AN. The present study examined differential levels of methylation at various CG sites of the OXTR gene in 69 women with active AN (AN-Active), 21 in whom AN was in remission (AN-Rem) and 35 with no eating disorder (NED). Within each group, we explored the correlation between methylation and measures of social behaviour such as insecure attachment and social avoidance. Hypermethylation of a number of CG sites was seen in AN-Active participants as compared with AN-Rem and NED participants. In the AN-Rem sample, methylation at CG27501759 was significantly positively correlated with insecure attachment (r = .614, p = .003, permutation Q = 0.008) and social avoidance (r = .588, p = .005, permutation Q = 0.0184). Our results highlight differential methylation of the OXTR gene among women with AN, those in remission from AN, and those who never had AN and provide some evidence of associations between OXTR methylation and social behaviour in women remitted from AN.

OBJECTIVE: Although hospitalization is sometimes necessary when treating individuals with anorexia nervosa, the available literature provides limited guidance to inform decisions surrounding optimal components or duration of inpatient treatments. We report observational data comparing outcomes of two inpatient treatments. The first was longer and more strictly structured around a Contingency Management Protocol (CMP) emphasizing external incentives for achieving weight-restoration goals; the second was a shorter Autonomy Support Protocol (ASP) that progressively increased patient autonomy around meal management without external incentives. METHOD: We compared data from 41 patients who participated in the ASP to a historical sample of 41 patients treated using the CMP. At admission, discharge, and post-treatment follow-up, participants completed the Eating Disorder Examination Questionnaire and the Behavior and Symptom Identification Scale-32, and we measured height and weight to compute body mass index. RESULTS: Multilevel modeling analyses that controlled for time in treatment and time in follow-up indicated the two protocols yielded equivalent in-treatment gains and post-treatment loss of gains. DISCUSSION: Our results indicate that shorter inpatient stays emphasizing autonomous control over eating behavior may yield outcomes that are equivalent to those of lengthier, more stringent, and more costly approaches implicating external incentives and controls.

Background: This study explored state-related tendencies in DNA methylation in people with anorexia nervosa. Methods: We measured genome-wide DNA methylation in 75 women with active anorexia nervosa (active), 31 women showing stable remission of anorexia nervosa (remitted) and 41 women with no eating disorder (NED). We also obtained post-intervention methylation data from 52 of the women from the active group. Results: Comparisons between members of the active and NED groups showed 58 differentially methylated sites (Q < 0.01) that corresponded to genes relevant to metabolic and nutritional status (lipid and glucose metabolism), psychiatric status (serotonin receptor activity) and immune function. Methylation levels in members of the remitted group differed from those in the active group on 265 probes that also involved sites associated with genes for serotonin and insulin activity, glucose metabolism and immunity. Intriguingly, the direction of methylation effects in remitted participants tended to be opposite to those seen in active participants. The chronicity of Illness correlated (usually inversely, at Q < 0.01) with methylation levels at 64 sites that mapped onto genes regulating glutamate and serotonin activity, insulin function and epigenetic age. In contrast, body mass index increases coincided (at Q < 0.05) with generally increased methylation-level changes at 73 probes associated with lipid and glucose metabolism, immune and inflammatory processes, and olfaction. Limitations: Sample sizes were modest for this type of inquiry, and findings may have been subject to uncontrolled effects of medication and substance use. Conclusion: Findings point to the possibility of reversible epigenetic alterations in anorexia nervosa, and suggest that an adequate pathophysiological model would likely need to include psychiatric, metabolic and immune components.

OBJECTIVE: To validate the Autonomous and Controlled Motivation for Treatment Questionnaire (ACMTQ) for use in women with an eating disorder (ED). METHOD: Data were available for 463 individuals. We assessed factor structure, internal reliability, test-retest reliability, convergent/divergent validity, and incremental predictive validity. RESULTS: Our data showed acceptable fit to our hypothesized model (comparative fit index = 0.92, root mean square error of approximation = 0.09, standardized root mean square residual = 0.09). We found test-retest reliability of 0.73 for both the autonomous (α = 0.85) and controlled (α = 0.80) subscales. Autonomous scores were more strongly associated with motivation measures (ß = 0.37; 0.46) than with ED severity measures (ß = -0.10; -0.18). Associations between autonomous motivation and symptom improvement over time supported predictive validity. Controlled motivation was associated with lower motivation (ß = 0.02; -0.31) and with higher ED severity (ß = 0.12; 0.47). CONCLUSION: Our results suggest that the ACMTQ is valid for use in women with EDs and lend support to the validity of findings from previous ED studies that have used the ACMTQ.

According to Self-Determination Theory, when motivation to reach an objective is fully internal, it is said to be "autonomous"; when driven by external incentives, it is said to be "controlled". Previous research has indicated that autonomously motivated individuals show better response to treatments for eating disorders. OBJECTIVE: In individuals undergoing different intensities of outpatient treatment for an eating disorder, we sought to assess associations between autonomous and controlled motivations and response to treatment on the one hand, and likelihood of dropping out of treatment, on the other. METHOD: Seven hundred seventy adults meeting DSM-5 criteria for an eating disorder (216 with Anorexia Nervosa, 282 with Bulimia Nervosa, and 272 with Other Specified Feeding or Eating Disorder) were included in this study. Before an interval of outpatient treatment, individuals completed the Eating Disorder Examination Questionnaire and the Autonomous and Controlled Motivations for Treatment Questionnaire. Participants completed the Eating Disorder Examination Questionnaire again at one or two subsequent timepoints. RESULTS: After controlling for diagnosis, treatment intensity, and number of previous treatments, analyses showed that higher autonomous motivation was associated with better response on eating-disorder overall symptoms and lower likelihood of dropping out of treatment. In contrast, controlled motivation was not associated with response to treatment. DISCUSSION: Our results suggest that autonomous motivation has trans-diagnostic influence upon response to various intensities of treatment for an eating disorder. In support of an autonomy supportive approach to treatment, findings link autonomous motivation with more favorable outcome.

RESUMO
We describe the implementation and impact of a province-wide program of knowledge exchange (KE), aimed at developing capacity for the treatment of people with eating disorders (EDs). The program is designed to equip clinicians working in nonspecialized health-care installations with skills to evaluate and treat people with EDs. Trainings were conducted at 21 institutions. The majority of clinicians reported satisfaction with the KE program and indicated that the trainings enhanced their confidence and ability to treat patients with EDs. A subset of clinicians received case supervision with a specialist ED therapist and followed patients with EDs (n = 119). Treated patients showed significant improvements on eating and depressive symptoms, and reported satisfaction with the treatments they received.
