Response to "Considerations in selecting comparison conditions in psychotherapy trials: Recommendations for future research".

Several researchers who have evaluated (IPT) wrote a commentary arguing that the group-delivered IPT treatment for eating disorders that we adapted and used in a recent trial (Stice, Rohde, et al., 2023) was less effective than the new dissonance-based eating disorder treatment () because the group-delivered IPT did not contain all core elements, was not developmentally appropriate, was not tailored for people with eating disorders, and because our team lacked sufficient IPT expertise. In response, we note that the group-delivered IPT that we evaluated produced higher abstinence from binge eating and compensatory weight control behaviors (40%) than did individually delivered IPT in the only trial that also evaluated this treatment with a broad range of eating disorders (33%; Fairburn et al.

Application of implementation science frameworks to inform the adaptation process of an evidence-based eating disorder prevention program for high-risk perinatal individuals.

Background: The perinatal period is a high-risk time for body dissatisfaction and disordered eating. Evidence-based interventions for disordered eating have not been adapted to address the needs of this population. We describe the process of adapting the Body Project, an evidence-based eating disorder (ED) prevention program, for pregnant individuals with histories of disordered eating behaviors.

Neural risk factors that predict the future onset of binge eating or compensatory weight control behaviors: A prospective 4-year fMRI study.

Background: We conducted a prospective study to advance knowledge of biological factors that predict the future onset of binge eating and compensatory weight control behaviors because few biological risk factors for eating pathology have been identified.

Methods: Adolescent girls free of binge eating or compensatory behaviors ( = 88;  = 14.5; [SD = 0.

Prospective reciprocal relations between psychosocial impairment and eating disorder symptoms in a high-risk sample.

Impairment in psychosocial functioning increases risk for future onset of eating disorders and a treatment that produced larger reductions in eating disorder symptoms also produced larger improvements in psychosocial functioning. However, no studies have tested whether there is a prospective reciprocal relationship between psychosocial impairment and eating disorder symptoms. Accordingly, the current study tested the hypotheses that baseline psychosocial functioning would predict future increases in eating disorder symptoms and that baseline eating disorder symptoms would predict future increases in psychosocial impairment.

Predictive equation derived from 6,497 doubly labelled water measurements enables the detection of erroneous self-reported energy intake.

Nutritional epidemiology aims to link dietary exposures to chronic disease, but the instruments for evaluating dietary intake are inaccurate. One way to identify unreliable data and the sources of errors is to compare estimated intakes with the total energy expenditure (TEE). In this study, we used the International Atomic Energy Agency Doubly Labeled Water Database to derive a predictive equation for TEE using 6,497 measures of TEE in individuals aged 4 to 96 years.

A preliminary randomized trial of a brief dissonance-based type 2 diabetes prevention programme for adults with pre-diabetes.

Objective: Conduct a preliminary randomized trial that compared a 6-week type 2 diabetes (T2D) prevention programme to an educational video control for adults with pre-diabetes.

Methods: Adults (N = 62) with pre-diabetes were randomized to the group-delivered Project Health T2D or an educational video control, completing measures at pre-test, post-test and 3-month follow-up.

Results: Participants randomized to the intervention versus control condition showed significantly greater reductions in body fat (d = 0.

Predictors of the sustainability for an evidence-based eating disorder prevention program delivered by college peer educators.

Background: Despite ongoing efforts to introduce evidence-based interventions (EBIs) into mental health care settings, little research has focused on the sustainability of EBIs in these settings. College campuses are a natural place to intervene with young adults who are at high risk for mental health disorders, including eating disorders. The current study tested the effect of three levels of implementation support on the sustainability of an evidence-based group eating disorder prevention program, the Body Project, delivered by peer educators.

Risk Factors That Predict Future Onset of Anorexia Nervosa, Bulimia Nervosa, Binge Eating Disorder, and Purging Disorder in Adolescent Girls.

Because very few prospective studies have identified risk factors that predicted future onset of threshold/subthreshold anorexia nervosa (AN), bulimia nervosa (BN), binge eating disorder (BED), and purging disorder (PD), we analyzed prospective data collected from a large cohort of adolescent girls followed over an 8-year period to advance knowledge about risk factor specificity. Adolescent girls recruited from middle schools in Texas (N = 492; M age = 13.02 [SD = 0.

The diabetes body project: Study protocol of a multi-site trial of a virtually delivered eating disorder prevention program for young women with type 1 diabetes.

Aim: Young women with type 1 diabetes are a high-risk population for eating disorders (ED). Prevention programs are lacking. In young women without diabetes, the Body Project has produced reductions in ED risk factors, ED symptoms and future ED onset.

A pilot study of a virtually delivered dissonance-based eating disorder prevention program for young women with type 1 diabetes: within-subject changes over 6-month follow-up.

Introduction: In an uncontrolled study, we previously demonstrated the feasibility and preliminary efficacy of our virtual diabetes-specific version () of the eating disorder (ED) prevention program the . The aim of the current study was to evaluate further this program for women with type 1 diabetes (T1D) by assessing within-subject changes in outcomes from pretest over 6-month follow-up.

Methods: Young women with T1D aged 16-35 years were invited to participate in groups.

Cost-effectiveness of Intervention Implementation Support for Reducing Eating Disorder Symptoms Among College Students.

Implementation support for prevention interventions is receiving increased attention, as many organizations receive training in evidence-based practices but do not deliver the interventions optimally. The Body Project, a four-session program, significantly reduces eating disorder symptoms and future disorder onset among group participants when delivered by peer educators at colleges/universities. Costs and cost-effectiveness of the program were examined using data from a randomized trial that compared three levels of implementation support at 63 colleges: (1) a train-the-trainer (TTT) workshop alone, (2) TTT plus a technical assistance (TA) workshop, or (3) TTT plus TA plus monthly quality assurance (QA) consultations.

The "Young Athlete Body Project"-A pilot study evaluating the acceptability of and results from an eating disorder prevention program for adolescent athletes.

Background: The high frequency of eating disorders (EDs) in sports speaks of a need for early-stage preventive measures.

Objectives: This study evaluated the acceptability of an age, sex, and sports adapted version of the "Body Project" and changes in mental health symptoms.

Methods: This noncontrolled pilot study included a class of athletes from 18 sports (N = 73, 13-14 years) at a sport-specialized junior high school in six small-group workshops.

A randomized trial of two group-delivered transdiagnostic eating disorder treatments: Dissonance-based treatment versus interpersonal psychotherapy.

Objective: Test whether a group-delivered dissonance-based transdiagnostic eating disorder treatment, Body Project Treatment (BPT), produces greater reductions in eating disorder symptoms and higher abstinence from eating disorder behaviors and remittance from eating disorder diagnoses than group-delivered transdiagnostic interpersonal psychotherapy (IPT).

Method: Women with a range of eating disorders (N = 73) were randomized to 8-week group-implemented BPT or IPT and completed surveys and masked diagnostic interviews at pretest, posttest, and 6-month follow-up.

Results: Participants randomized to BPT versus IPT showed significantly greater reductions in eating disorder symptoms (d = -.

Prospective reciprocal relations between social support and eating disorder symptoms.

Prospective studies have found inconsistent relations between social support deficits and future increases in eating disorder symptoms. Furthermore, no prospective study has tested whether elevated eating disorder symptoms predict a future erosion of social support. Accordingly, the current study investigated the prospective reciprocal relations between perceived social support from both parents and peers and eating disorder symptoms in adolescent girls.

Effectiveness of virtually delivered Body Project groups to prevent eating disorders in young women at risk: a protocol for a randomized controlled trial.

Background: Eating disorders (EDs) are a group of mental illnesses associated with significant psychological and physiological consequences. Overall, only about one-fifth of individuals with EDs receive treatment and treatment is effective for only about one-third for those who receive care. The development and implementation of effective prevention approaches for those at risk is therefore pivotal.

Evaluation of a novel eating disorder prevention program for young women with type 1 diabetes: A preliminary randomized trial.

Objective: Evaluate whether the Body Project prevention program adapted for young women with type 1 diabetes (Diabetes Body Project) reduces eating disorder (ED) risk factors and symptoms.

Methods: Young women (aged 15-30) at high-risk for EDs due to having type 1 diabetes and body image concerns (N = 55) were randomized to virtually delivered Diabetes Body Project groups or an educational control condition, completing measures at pretest, posttest, and 3-month follow-up.

Results: Diabetes Body Project versus the control participants showed significantly greater reductions in thin-ideal internalization, body dissatisfaction, diabetes distress, diabetes eating pathology, and ED symptoms by posttest, and greater reductions in diabetes eating pathology and ED symptoms, and greater improvements in quality of life by 3-month follow-up, which were medium to large effects (d's ranged from -0.

Greater male variability in daily energy expenditure develops through puberty.

There is considerably greater variation in metabolic rates between men than between women, in terms of basal, activity and total (daily) energy expenditure (EE). One possible explanation is that EE is associated with male sexual characteristics (which are known to vary more than other traits) such as musculature and athletic capacity. Such traits might be predicted to be most prominent during periods of adolescence and young adulthood, when sexual behaviour develops and peaks.

Sequencing of symptom emergence in anorexia nervosa, bulimia nervosa, binge eating disorder, and purging disorder in adolescent girls and relations of prodromal symptoms to future onset of these eating disorders.

Background: To advance knowledge regarding the etiology of eating disorders, we characterized the sequencing of eating disorder symptom emergence for adolescent girls who subsequently developed anorexia nervosa (AN), bulimia nervosa (BN), binge eating disorder (BED), and purging disorder (PD) for community-recruited adolescents and tested whether prodromal symptoms increased risk for future onset of each eating disorder.

Methods: Data collected from adolescent girls ( = 496; age = 13.02, s.

The Transdiagnostic Intervention for Sleep and Circadian Dysfunction (TranS-C) for serious mental illness in community mental health part 2: study protocol for a hybrid type 2 effectiveness-implementation cluster-randomized trial using train-the-trainer.

Background: Train-the-trainer (TTT) is a promising method for implementing evidence-based psychological treatments (EBPTs) in community mental health centers (CMHCs). In TTT, expert trainers train locally embedded individuals (i.e.

Setting and Provider Predictors of Implementation Success for an Eating Disorder Prevention Program Delivered by College Peer Educators.

Introduction: College students face increased risk for a variety of mental health problems but experience barriers to treatment access. Prevention programs, including those implemented by peer educators, may decrease treatment needs and increase service access. We examined the implementation of an evidence-based eating disorder prevention program, Body Project, delivered by college peer educators at 63 colleges/universities, comparing three levels of implementation support: (1) Train-the-Trainer (TTT) training; (2) TTT plus a technical assistance workshop (TTT + TA); and (3) TTT + TA with one year of quality assurance calls (TTT + TA + QA).

Elevated reward, emotion, and memory region response to thin models predicts eating disorder symptom persistence: A prospective functional magnetic resonance imaging study.

Because few studies have identified biological factors that predict the persistence of eating pathology, we tested the hypotheses that elevated responsivity of brain regions implicated in reward valuation to thin models and high-calorie binge foods would predict the persistence of eating pathology. We analyzed data from 146 women ( = 21.87 ± 3.

Contextualizing the Neural Vulnerabilities Model of Obesity.

In recent years, investigators have focused on neural vulnerability factors that increase the risk of unhealthy weight gain, which has provided a useful organizing structure for obesity neuroscience research. However, this framework, and much of the research it has informed, has given limited attention to contextual factors that may interact with key vulnerabilities to impact eating behaviors and weight gain. To fill this gap, we propose a , extending the existing theory to more intentionally incorporate contextual factors that are hypothesized to interact with neural vulnerabilities in shaping eating behaviors and weight trajectories.
