Outcomes of a Virtual Day Treatment Program for Adults With Eating Disorders-Comparison With In-Person Day Treatment.

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.

In-person versus virtual therapy in outpatient eating-disorder treatment: A COVID-19 inspired study.

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.

Barriers and facilitators to providing autonomy supportive counselling to individuals seeking treatment for an eating disorder.

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.

A longitudinal, epigenome-wide study of DNA methylation in anorexia nervosa: results in actively ill, partially weight-restored, long-term remitted and non-eating-disordered women

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.

A naturalistic comparison of two inpatient treatment protocols for adults with anorexia nervosa: Does reducing duration of treatment and external controls compromise outcome?

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.

A Readiness Ruler for Assessing Motivation to Change in People with Eating Disorders.

OBJECTIVE: We examined the psychometric properties of the Eating Disorder Readiness Ruler a simple self-report instrument designed to enable rapid assessment of readiness to change problematic eating behaviours in people with clinical eating disorders. METHOD: We administered the ED-RR, the Eating Disorders Examination Questionnaire and a measure of autonomous and controlled motivation for change to 206 individuals receiving outpatient treatment for an eating disorder. RESULTS: A principal axis factoring analysis of the ED-RR yielded a significant two-factor solution (explaining 59% of variance)-one factor pertaining to restriction and body image preoccupation (four items), the other to binge-eating and vomiting symptoms (two items). The ED-RR showed good internal consistency (alpha coefficients for the two factors being .77 and .84 respectively). Furthermore, individuals reporting higher readiness showed higher scores on independent measures of autonomous motivation and greater symptom reductions over time. DISCUSSION: Results suggest that the ED-RR is a psychometrically sound tool with potential clinical utility. Copyright © 2017 John Wiley & Sons, Ltd and Eating Disorders Association.

A prospective study of effects of prenatal maternal stress on later eating-disorder manifestations in affected offspring: preliminary indications based on the Project Ice Storm cohort.

BACKGROUND: Research associates maternal stress exposures (especially when occurring late in gestation) with heightened risk of subsequent emotional and behavioral problems in affected offspring. However, as yet, no study has examined the association between prenatal maternal stress (PNMS) and affected children's risk of anorexia- or bulimia-type eating disturbances. OBJECTIVE: To study the influences of PNMS on later disordered eating in exposed offspring. METHOD: We used the Eating Attitudes Test (EAT)-26 to measure eating attitudes and behaviors in 54 thirteen-year olds whose mothers had been exposed, while pregnant with these children, to the 1998 Quebec Ice Storm-a natural disaster regarded as a model of exposure to severe environmental stress. Mothers' stress was measured shortly after exposure to the storm using established indices of objective and subjective stress. RESULTS: Hierarchical multiple linear regression analyses indicated that once variance owing to children's body mass index and sex was accounted for, stress exposures during the third trimester of pregnancy predicted elevated EAT-26 scores in affected children-perhaps even more so when levels of objective stress were high. DISCUSSION: Third trimester exposure to PNMS, especially when objectively severe, seems to be associated with increased eating-disorder-linked manifestations in affected early adolescents.

Development of a transdiagnostic digital interactive application for eating disorders: psychometric properties, satisfaction, and perceptions on implementation in clinical practice.

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.

DNA methylation in people with anorexia nervosa: Epigenome-wide patterns in actively ill, long-term remitted, and healthy-eater women.

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.

Predicting social functioning in schizotypy: an investigation of the relative contributions of theory of mind and mood.

Theory of mind (ToM) is an aspect of social cognition that refers to the ability to make inferences about the thoughts, feelings, and intentions of other people. It is believed to be related to social functioning. Previous investigations of ToM in schizotypy have yielded mixed results. Using a correlational approach, the present study explored the relationship between schizotypal traits, ToM, neurocognition, depressed mood, and social functioning in a sample of 50 undergraduate students. Schizotypy was related to poor social functioning. Contrary to predictions, schizotypal traits were not associated with impaired ToM. In fact, schizotypal traits were associated with enhanced performance on a ToM task that involved detection of ironic statements. However, strong relationships emerged among schizotypy, depressed mood, and social functioning, highlighting the need to also examine depression when assessing the relations between elevated schizotypy and poor social functioning.

Life events and high-trait reactivity together predict psychotic symptom increases in schizophrenia.

Psychotic symptoms are exacerbated by stressful life events in schizophrenia patients as a group. Some individuals appear to be more vulnerable than others in this regard. This study tested whether schizophrenia patients are highly emotionally reactive compared with controls and whether the level of trait emotional reactivity in patients influences the degree to which they respond to life stressors with exacerbations of psychosis. Schizophrenic outpatients and nonpsychiatric controls were assessed for levels of trait emotional reactivity, arousability, and trait anxiety. Severity of symptoms was also rated in the patients. Patients were then followed up 9 months later, assessed for independent stressful life events occurring during the month before the follow-up session, and reassessed for symptom levels. The patients scored higher than the control subjects on all 3 measures of reactivity at the initial assessment. At follow-up, the occurrence of potentially stressful life events predicted increases in psychotic symptoms in patients, and there was a significant interaction between level of initial trait reactivity and the occurrence of life events in the prediction of these increases. High-trait-reactive patients showed increases in psychotic symptoms in response to life stressors, whereas low-trait-reactive patients did not. These findings support the idea that patients as a group have higher than normal levels of trait reactivity and also that patients with very high levels of trait reactivity are at elevated risk of psychotic relapse under stress. Such patients might benefit particularly from interventions designed to assist them in coping with potentially stressful life events and circumstances.

Emotion word use in the conversational speech of schizophrenia patients.

INTRODUCTION: Many recent studies have found that, although schizophrenia patients tend to display diminished facial expressions of emotion, they report levels of emotional experiences that are similar to those of controls. Although these findings are very informative, it is unknown whether such dissociation exits for other modalities such as verbal expression of emotion. The purpose of this study was to investigate the association between the use of emotion words during a free speech task and subjective experience of emotion in schizophrenia patients and controls. METHODS: Speech samples of 48 schizophrenia patients and 48 nonpsychiatric control individuals were compared on the type and amount of emotional words used, as well as on the level of self-reported stress experienced while providing descriptions of themselves. RESULTS: Groups did not differ in the amount or type of emotion words uttered during the free speech task. Patients, however, found the task more stressful than controls. Emotion word use and subjective emotional experience were not related in either group. CONCLUSIONS: Results do not fully support prior findings, but are consistent with the notion of a lack of correspondence between the expression and experience of emotion.

The cognitive origins of specific types of schizophrenic speech disturbances.

OBJECTIVE: Cognitive impairments associated with schizophrenia might be expected to have a marked impact on the ability to produce coherent speech, yet associations between cognitive performance and speech disorder have typically been weak. Findings on this question may have been limited by measurement methods and by the heterogeneity of speech disorder. This study examined the contributions of impairments in sustained attention and sequencing abilities to schizophrenic speech disorder, measured in terms of communication failures and divided into different types of disorder. METHOD: Samples of natural speech were collected from severely ill inpatients with schizophrenia and nonpsychiatric comparison subjects and rated for frequencies of six types of communication failures: four structural and two nonstructural types. Subjects also completed a battery of cognitive tests assessing several facets of attention and sequencing ability. Hierarchical regression was used to identify cognitive contributors to communication failures. RESULTS: Impaired sustained attention was associated with more frequent structural and nonstructural communication failures. As predicted, impaired sequencing, and in particular conceptual sequencing, also made a substantial contribution to the structural communication failures, but not to the nonstructural ones. These findings held when global level of impairment was controlled statistically. Performance on the tests of attention and sequencing explained 56% of the variance in structural speech disorder. CONCLUSIONS: Schizophrenic speech disorder is heterogeneous in form and in cognitive underpinnings. Impairments in attention and sequencing abilities are highly predictive of communication failures related to language structure.

Language reactivity and work functioning in schizophrenia.

Some studies have found that the speech of certain schizophrenia patients becomes more disordered in stressful laboratory situations. It is unknown, however, whether affective reactivity of speech is associated with stress responsiveness of symptoms in the real world. This study examines whether language-reactive patients report more stress-related impairments in work functioning than language-nonreactive patients. Forty-six patients provided speech samples and completed a work history interview. It was found that the language-reactive patients were more likely than the language-nonreactive patients to endorse items pertaining to social anxiety and difficulty relating to others as reasons for their work difficulties. This suggests that language-reactive patients are more sensitive to social stressors than language-nonreactive patients.

Explaining variation in the premorbid adjustment of schizophrenia patients: the role of season of birth and family history.

UNLABELLED: Several studies have shown that patients with schizophrenia are more likely to be born in the winter and early spring than at any other time of the year. Furthermore, some studies have reported that winter-born patients differ from non-winter-born patients in terms of risk factors, symptoms, sensory abnormalities and brain morphology. Associations between season of birth and premorbid adjustment (PMA), however, are still unclear. OBJECTIVE: The main purpose of this study was to determine whether winter-born and non-winter-born schizophrenia patients differ in terms of PMA and to examine how family history of schizophrenia-spectrum disorders may influence the association. METHOD: Data on four PMA dimensions (attention, internalizing, externalizing and social problems) and family history were gathered from 37 schizophrenia patients (26 males and 11 females) and their mothers. RESULTS: Non-winter-birth and a positive family history of schizophrenia-spectrum disorders were associated with worse PMA. Results suggest that, although no significant interaction was found, season of birth and family history appear to work together in explaining distinct dimensions of PMA.

Cortisol response and coping style predict quality of life in schizophrenia.

Stress and coping have been found to be strongly associated with quality of life (QOL). Compared to community controls (CC), individuals diagnosed with schizophrenia (SZ) report a lower QOL. Lower QOL in SZ may be explained by patients' tendency to react differently to stress and to use less effective coping strategies than CC, but no studies to date have examined these possible associations. A main goal of this study, therefore, was to examine the roles of stress response and coping style in explaining QOL in SZ and CC, while controlling for potential confounds including personality. Subjects were 30 SZ patients and 29 matched controls who completed the Trier Social Stress Test (TSST). Salivary cortisol was used as an objective measure of stress response. Participants rated their coping strategies with the Brief COPE, judged their QOL with the Satisfaction with Life Scale, and rated their personality using the NEO-Five Factor Inventory. Results indicate that, even when confounds are controlled for, blunted cortisol response predicts better QOL in SZ patients. Additionally, results suggest that more frequent use of coping strategies is associated with better QOL but only in patients with blunted cortisol response; those who showed an increase in cortisol in response to the TSST have better QOL the lower their coping score. Possible explanations and clinical implications of these findings are discussed.

Anxiety interacts with expressed emotion criticism in the prediction of psychotic symptom exacerbation.

Psychotic symptoms are exacerbated by social stressors in schizophrenia and schizoaffective disorder patients as a group. More specifically, critical attitudes toward patients on the part of family members and others have been associated with a higher risk of relapse in the patients. Some patients appear to be especially vulnerable in this regard. One variable that could affect the degree of sensitivity to a social stressor such as criticism is the individual's level of anxiety. The present longitudinal study assessed 27 relatively stable outpatients with schizophrenia or schizoaffective disorder and the single "most influential other" (MIO) person for each patient. As hypothesized, (1) patients with high critical MIOs showed increases in psychotic symptoms over time, compared with patients with low critical MIOs; (2) patients high in anxiety at the baseline assessment showed increases in psychotic symptoms at follow-up, compared with patients low in anxiety, and (3) patients with high levels of anxiety at baseline and high critical MIOs showed the greatest exacerbation of psychotic symptoms over time. Objectively measured levels of criticism were more predictive than patient-rated levels of criticism.

Attributional style in delusional patients: a comparison of remitted paranoid, remitted nonparanoid, and current paranoid patients with nonpsychiatric controls.

Many studies have found that people experiencing persecutory delusions have a marked tendency to use external-personal attributions when establishing the causes of negative events. Although nonclinical populations also tend to attribute negative events to external causes, those causes are typically believed to be universal in nature, rather than personal. The central goal of the present study was to investigate whether individuals with remitted persecutory delusions would display this external-personal bias regarding negative events, in comparison to remitted patients whose delusions were not paranoid in nature and to nonpsychiatric controls. Results indicate that currently paranoid patients were significantly more likely than all other groups, including the remitted paranoid group, to use external-personal attributions in negative events. Interestingly, all patient groups also were found to be significantly more likely than the controls to use internal-personal and internal-universal attributions when explaining negative events.

Coping in parents of schizophrenia patients with differing degrees of familial exposure to psychosis.

Over the past 50 years, parents have become more involved in the care of their schizophrenic sons and daughters. Although such responsibility can be gratifying, parents frequently report feeling burdened and distressed. These feelings may affect parents' coping strategies in times of stress. This study examined the effects of family history of psychosis on coping styles in parents of patients. Coping strategies of parents with and without additional first-degree relatives suffering from psychosis (besides the index son or daughter) and controls were compared. As predicted, more family history of psychosis was negatively related to coping ability in parents. Findings suggest that greater familial exposure to psychosis may have an adverse effect on their ability to deal with life stressors. Results are discussed in light of the possible influence of genetic and environmental factors.

Validation of a French version of the impact of event scale-revised.

OBJECTIVE: This report presents a French translation and validation of the Impact of Event Scale-Revised (IES-R) in a population of women exposed to a natural disaster during or preceding pregnancy. METHOD: A total of 223 francophone women who were either pregnant at the time of the 1998 ice storm or who became pregnant shortly thereafter completed the IES-R and other questionnaires 6 months after the disaster. RESULTS: The French IES-R has good internal consistency, with alpha coefficients ranging from 0.81 to 0.93 for its 3 subscales and total score. The test-retest reliability of the scale, although examined with another sample, proved to be satisfactory, with correlation coefficients ranging from 0.71 to 0.76 for its 3 subscales and total score. Its convergent validity with perceived life threat and general psychiatric symptoms was judged to be marginally acceptable. Finally, a principal components analysis was conducted and a 3-factor solution, which explained 56% of the variance, was retained: a hyperarousal factor (7 items), an avoidance factor (6 items), and an intrusion factor (6 items). CONCLUSIONS: The French version of the IES-R has satisfactory internal validity and test-retest reliability. Further, the factor structure of the translation was similar to the proposed theoretical structure of the IES-R.
