Longitudinal associations between response-style strategies and abnormal eating behaviors/attitudes in adolescents: a cross-lagged panel model. J Eat Disord 2024; 12:33.

Abstract
BACKGROUND Previous studies have suggested that response-style strategies (rumination, problem-solving, and distraction) can be risk or protective factors for the development of abnormal eating behaviors/attitudes (AEB) during adolescence. However, due to limited empirical data regarding the prospective effects of these strategies on AEB, further research is needed to clarify their role in developing AEB in adolescence. METHODS This study investigated the one-year lagged effects of response-style strategies on AEB in 24,883 fourth- to eighth-grade students in Japan between 2015 and 2019 using a cross-lagged panel model. Depressive symptoms and body mass index (BMI), which are reported to relate to AEB, were also included in the analytic model. The students self-reported their levels of response-style strategies, AEB, and depressive symptoms. We also evaluated BMI based on teachers' reports. RESULTS We found that greater rumination significantly predicted more severe AEB in the following year among students from all grades, with small to moderate effect sizes. In addition, distraction significantly predicted more severe binge eating/purging behaviors, but with very weak small effect sizes. Problem-solving did not predict any level of AEB. Furthermore, we observed significant reciprocal relationships between response-style strategies, AEB, and depressive symptoms. Positive reciprocal associations between BMI and AEB were also found except for some intervals. CONCLUSIONS We concluded that a decrease in rumination is critical to alleviating mental health problems, such as AEB and depressive symptoms, during adolescence. This suggests that interventions to reduce the level of rumination should be conducted in the early stages of adolescence. TRIAL REGISTRATION NUMBER Not Applicable.

Maas J, Simeunovic-Ostojic M, Bodde NMG. Is a dissonance-based group intervention targeting thin-ideal internalization a successful potential add-on for specialized eating disorder care? A randomized feasibility and acceptability pilot study. J Eat Disord 2023; 11:68. [PMID: 37131211 PMCID: PMC10152706 DOI: 10.1186/s40337-023-00784-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/30/2022] [Accepted: 04/12/2023] [Indexed: 05/04/2023] Open
Abstract
BACKGROUND Dissonance-based eating disorder programs have successfully targeted body dissatisfaction by challenging the thin beauty ideal in the preventive context and in groups of patients with a subthreshold and full threshold DSM-5 eating disorder. As there is a need for interventions specifically targeting thin-ideal internalization in (highly) specialized treatment centres, the present study adapted Stice's et al.'s Body Project for its use as an add-on treatment for severe eating disorders with the aims to identify whether it was feasible and acceptable in this treatment context, to determine any necessary modifications with regard to the treatment and study procedures, and to test preliminary effectiveness. METHODS The study was a randomized controlled pilot/feasibility trial. Thirty patients started in the Body Project group and 25 in the Psycho-education group. Measurements took place pre- and post-intervention, and at three and six months follow-up. Patients and staff evaluated treatment and study procedures, and patients completed questionnaires on thin-ideal internalization, body dissatisfaction, self-objectification, negative affect and eating disorder pathology. RESULTS The Body Project group and Psycho-education group both proved highly feasible and acceptable, as well as preliminarily effective, based on quantitative scores and qualitative feedback. Preliminary analyses showed that treatment effects did not differ between treatment groups. As both groups were an add-on to standard treatment, treatment effects cannot be disentangled from effects resulting from standard treatment. Qualitative feedback for the Body Project group included several recommendations for future implementation: increasing the number of treatment sessions, creating homogeneous therapy groups, and optimizing timing of the treatment. CONCLUSIONS Future research should examine further modifications to the Body Project group for severe eating disorders, as well as for whom, and when in the course of treatment the intervention is most effective. The present study also showed the benefits of implementing a structured Psycho-education group. We tested the feasibility and acceptability of a group intervention targeting the thin beauty ideal (Body Project group) in patients with severe eating disorders and compared this intervention to a group intervention focusing on psycho-education about eating disorders (Psycho-education group). Both interventions were added to standard treatment. We adapted the protocol for patients with severe eating disorders. Both the Body Project group and the Psycho-education group were evaluated by patients as well as staff as highly feasible and acceptable, and effects were positive. Treatment effects did not differ between treatment groups. As both treatments were an add-on to standard treatment, treatment effects cannot be disentangled from effects resulting from standard treatment. The study suggested further modifications to the Body Project group. Future research should examine these modifications as well as for whom, and when in the course of treatment the intervention is most effective. The present study also showed the benefits of implementing a structured Psycho-education group.

Cognitive-behavioral therapy and exercise training in adolescent females with elevated depression symptoms and at-risk for type 2 diabetes: Protocol for a randomized controlled trial. Contemp Clin Trials 2023; 128:107150. [PMID: 36918091 PMCID: PMC10288810 DOI: 10.1016/j.cct.2023.107150] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2023] [Revised: 03/09/2023] [Accepted: 03/10/2023] [Indexed: 03/13/2023]
Abstract
BACKGROUND Adolescent-onset type 2 diabetes (T2D) is a major public health concern of growing proportions. Prevention, therefore, is critical. Unfortunately, standard-of-care treatment for T2D prevention (e.g., exercise training) show insufficient effectiveness and do not address key modifiable barriers (e.g., depression symptoms) to exercise engagement. Depression symptoms are associated with both poorer physical fitness and greater insulin resistance, the key risk factor in adolescent-onset T2D. Thus, a targeted prevention approach that addresses depression symptoms in combination with exercise training may offer a novel approach to mitigating T2D risk. METHODS This manuscript describes the design and study protocol for a multi-site, four-arm randomized controlled trial comparing the efficacy of group cognitive-behavioral therapy, group exercise training, and their combinations for the targeted prevention of worsening insulin resistance in N = 300 adolescent females at-risk for T2D with BMI ≥85th percentile and elevated depression symptoms. All four intervention arms will run in parallel and meet weekly for 1 h per week for 6-week to 6-week segments (12 weeks total). Outcomes are assessed at baseline, 6-week mid-treatment, 12-week follow-up, and 1-year follow-up. RESULTS The primary outcome is insulin resistance. Key secondary outcomes include insulin sensitivity, cardiorespiratory fitness, physical activity, depression symptoms, and body measurements. CONCLUSION Study findings will guide the ideal sequencing of two brief T2D prevention interventions for ameliorating the course of insulin resistance and lessening T2D risk in vulnerable adolescents. These interventions will likely be cost-effective and scalable for dissemination, having the potential for significant public health impact on communities at risk for T2D.

Abstract
BACKGROUND Many previous studies have investigated the risk factors associated with eating disorders (EDs) from the perspective of emotion regulation (ER). However, limited research has investigated interactions between co-existing risk factors for EDs, especially in China where research in EDs is underrepresented. METHODS This study examined core risk factors related to maladaptive eating behaviors and ER, and how their interactions affect the detection of EDs. Using machine learning, a decision tree model was constructed on a data set of 830 non-clinical Chinese young women with an average age of 18.91 years (SD = 0.95). The total data set was split into training and testing data sets with a ratio of 70 to 30%. RESULTS Body image inflexibility was identified as the major classifier for women at high risk of EDs. Furthermore, interactions between body image inflexibility, psychological distress, and body dissatisfaction were important in detecting women at high risk of EDs. Overall, the model classifying women at high-risk for EDs had a sensitivity of 0.88 and a specificity of 0.85 when applied to the testing data set. CONCLUSIONS Body image inflexibility, psychological distress, and body dissatisfaction were identified as the major classifiers for young women in China at high risk of EDs. Researchers and practitioners may consider these findings in the screening, prevention, and treatment of EDs among young women in China.

Abstract
Objective Obesity is a significant health concern among college populations, and trauma-exposed students are particularly at risk for behaviors associated with weight gain. There is need for further understanding of factors that may contribute to increased obesity among this population. Participants: Participants included 139 trauma-exposed college students with obesity (76.3% females; Mage = 25.4 years, SD = 8.07). Method: The current cross-sectional study examined distress tolerance in terms of expectancies of eating to help manage negative affect and to lead to feeling out of control among trauma-exposed college students with obesity. Results: Results indicated that lower perceived distress tolerance was associated with greater expectancies of eating to help manage negative affect and to lead to feeling out of control. Conclusions: These findings suggest that distress tolerance may be a clinically significant target for treatment in order to better understand and treat expectancies of eating among trauma-exposed college students with obesity.

Abstract
OBJECTIVE Loss of control over eating (LOC) is common among adolescents and is associated with negative developmental outcomes. Low self-regulation, and specifically low inhibitory control, is increasingly emphasized as an underlying factor in LOC. However, the specific context in which these capacities fail remains unclear. The affect regulation model proposes that negative affect may trigger LOC; however, research has mostly assessed trait negative affect using questionnaires, whereas measuring state negative affect is needed to determine its triggering role. Therefore, this study examined the interaction between inhibitory control and state negative affect in predicting LOC among adolescents using an experimental mood-induction design. METHOD Participants were 50 adolescents (10-18 years; 76% girls) from the general community. Participants first reported on their self-regulatory and inhibitory control capacities. They were then assigned to a sad or neutral mood-induction (using a film clip), followed by a multi-item food buffet from which they could eat as much as they liked. Finally, participants reported on their experience of loss of control while eating. RESULTS Inhibitory control (but not self-regulation in general) interacted with the mood-induction to predict LOC. Adolescents with low inhibitory control experienced significantly more LOC, but only in the sad mood condition. DISCUSSION The experience of negative affect appears to be an important trigger for LOC in adolescents with low inhibitory control. With a view to prevention and early intervention of LOC, inhibitory control training may be most effective in contexts where adolescents experience high levels of negative affect.

Abstract
Understanding factors that contribute to eating disorders, which affect 13% of females, is critical to developing effective prevention and treatment programs. In this paper, we summarize results from prospective studies that identified factors predicting onset and persistence of eating disorders and core symptom dimensions. Next, implications for intervention targets for prevention, and treatment interventions from the risk- and maintenance-factor findings are discussed. Third, given that evidence suggests eating disorders are highly heritable, implying biological risk and maintenance factors for eating disorders, we offer working hypotheses about biological factors that might contribute to eating disorders, based on extant risk factor findings, theory, and cross-sectional studies. Finally, potentially fruitful directions for future research are presented. We suggest that it would be useful for experimental therapeutics trials to evaluate the effects of reducing the risk factors on future onset of eating pathology and on reducing maintenance factors on the risk for persistence of eating pathology, and encourage researchers to utilize prospective high-risk studies so that knowledge regarding potential intervention targets for prevention and treatment interventions for eating disorders can be advanced. Using the most rigorous research designs should help improve the efficacy of prevention and treatment interventions for eating disorders.

Abstract
The aim of this article is to show selected psychological mechanisms involved in the onset and maintenance of obesity in children and youth. This work presents a review of the literature related to the psychological determinants of obesity from different theoretical approaches. The role of the mother-child relationship, as well as the specific characteristics of the relationships within the family, have been emphasized in the onset of the disorder. Another topic discussed were the specifics of the body experience and certain body image distortions that promote the maintenance of the obese state. The control deficit caused by family relationships was also described.

Abstract
Objective To examine maternal and child internalizing symptoms as predictors of early adolescent emotional eating in a longitudinal framework spanning three critical developmental periods (preschool, elementary school, and early adolescence). Methods Participants were 170 children recruited at preschool age for a longitudinal study. When children were 5.25 years, their mothers completed ratings of their own internalizing symptoms. During the spring of 4th grade, children completed measures of internalizing symptoms. In early adolescence, youth completed a measure of emotional eating. Results Maternal and child internalizing symptoms predicted adolescent emotional eating. The results indicated that child psychopathology moderated the association between maternal psychopathology (except for maternal anxiety) and early adolescent emotional eating. There was no evidence of mediation. Conclusions Pediatric psychologists are encouraged to provide early screening of, and interventions for, maternal and child internalizing symptoms to prevent children's emotional eating.

Abstract
This review included 136 published randomized controlled trials (RCTs) of youth cognitive behavioral therapy (CBT) treatments. We aimed to test the premise that evidence-based youth treatments can be better differentiated from each other by applying more nuanced standards of evidence. Accordingly, we applied three standards to this article sample to determine how many treatments produced significant results: (a) on multiple target symptom measures, (b) at follow-up, and/or (c) against an active comparison group. We identified how many trials met standards individually and in combination. Although 87 of the 136 articles produced at least one significant treatment result at post-assessment, the subsets of "passing" articles were smaller and varied for any one of our three standards, with only 11 articles (8%) meeting all three standards simultaneously. Implications are discussed regarding the definition of "evidence-based," the need for multi-parameter filtering in treatment selection and clinical decision making, and future directions for research. We ultimately argue the value in assessing youth treatments for different types of evidence, which is better achieved through dynamic sets of standards, rather than a single approach to assessing general strength of evidence.

Abstract
Depression is a problem among college students in China. Yet the use of preventative group cognitive-behavioral (CB) intervention is rare. One hundred and eighty Chinese college students who were identified as being at risk for depression were randomly assigned to three groups: 1) a brief group cognitive-behavioral (CB) intervention, 2) a supportive group (SG) intervention, and 3) a wait-list control condition. The Zung Self-Rating Depression Scale (SDS), the Zung Self-Rating Anxiety Scale (SAS), and the Chinese College Student Adjustment Scale (CCSAS) were administered at pre-test, post-test, and six-month follow-up. Analysis of variance (ANOVA) conducted among the three groups revealed that the CB group demonstrated significantly less increase in measures of primary symptoms of anxiety and depression than the wait-list controls at post-test and six-month follow-up. The prevention effect of the SG group was significant only at the six-month follow-up. CB participants also showed significantly greater improvements in social adjustment than did SG participants and controls at the post-test and six-month follow-up.

[PMID: 26013185 PMCID: PMC4543580 DOI: 10.1002/eat.22431] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/11/2013] [Revised: 03/26/2015] [Accepted: 03/26/2015] [Indexed: 11/12/2022]
Abstract
OBJECTIVE This study explored the cross-sectional and predictive effect of drive for thinness and/or negative affect scores on the development of self-reported anorexia nervosa (AN) and bulimia nervosa (BN). METHOD K-means were used to cluster the Eating Disorder Inventory-Drive for Thinness (DT) and Child Behavior Checklist Anxious/Depressed (A/D) scores from 615 unrelated female twins at age 16-17. Logistic regressions were used to assess the effect of these clusters on self-reported eating disorder diagnosis at ages 16-17 (n = 565) and 19-20 (n = 451). RESULTS DT and A/D scores were grouped into four clusters: Mild (scores lower than 90th percentile on both scales), DT (higher scores only on DT), A/D (higher scores only on A/D), and DT-A/D (higher scores on both the DT and A/D scales). DT and DT-A/D clusters at age 16-17 were associated cross-sectionally with AN and both cross-sectionally and longitudinally with BN. The DT-A/D cluster had the highest prevalence of AN at follow-up compared with all other clusters. Similarly, an interaction was observed between DT and A/D that predicted risk for AN. DISCUSSION Having elevated DT and A/D scores may increase risk for eating disorder symptomatology above and beyond a high score on either alone. Findings suggest that cluster modeling based on DT and A/D may be useful to inform novel and useful intervention strategies for AN and BN in adolescents.

Abstract
Symptoms of depression and eating disorders increase during adolescence, particularly among girls, and they tend to co-occur. Despite this evidence, there is meager research on whether depression increases the risk of future eating pathology, or vice versa, and we do not know whether these processes are different for adolescent girls and boys. Accordingly, this study explored the prospective reciprocal associations between depressive symptoms and disordered eating at different time points from preadolescence to mid-adolescence and tested the moderator effect of gender on these associations. A community-based sample of Spanish youth (N = 942, 49 % female) was assessed at ages of approximately 10-11 (T1), 12-13 (T2), 14-15 (T3), and 16-17 (T4) years. The bidirectional relationships between depressive symptoms and disordered eating were estimated in an autoregressive cross-lagged model with latent variables. A unidirectional, age-specific association between depressive symptoms at T1 and disordered eating at T2 was found. No other significant cross-lagged effect emerged, but the stability of the constructs was considerable. Gender did not moderate any of the links examined. Regardless of gender, the transition from childhood to adolescence appears to be a key period when depressive symptoms foster the development of disordered eating. These findings suggest that early prevention and treatment of depression targeting both girls and boys may result in lower levels of depressive symptoms and disordered eating in adolescence.

Abstract
Depression rates rise dramatically from the early to late adolescence. Especially young adolescent girls with elevated depressive symptoms are at high risk for developing a depression during adolescence or adulthood. Therefore, the prevention of depression is important especially in this high-risk group. The aim of the present study was to examine the effectiveness of the Cognitive Behavioral Therapy (CBT) component of the depression prevention program 'Op Volle Kracht' (OVK) among Dutch adolescent girls with elevated depressive symptoms. In total, 102 adolescent girls (11-15 years) in the first and second year of secondary school participated in this study. The girls in the experimental group (n = 50) followed the eight CBT-lessons of OVK and reported depressive symptoms 1 week prior to the start of the lessons, after every lesson, at one-month and 6-months follow-up. The girls in the control group (n = 52) exclusively reported depressive symptoms at the same time points. Latent Growth Curve Modeling showed that the decrease in depressive symptoms was significantly larger for girls in the experimental group compared to the girls in the control group. Furthermore, it was found that at 6-months follow-up, the girls in the experimental group had significantly lower levels of depressive symptoms compared to the girls in the control group. These findings indicate that the CBT-component of OVK effectively reduces depressive symptoms in short term and possibly prevents the development of a clinical depression.

Binge-like eating attenuates nisoxetine feeding suppression, stress activation, and brain norepinephrine activity. PLoS One 2014; 9:e93610.

Abstract
Stress is often associated with binge eating. A critical component of the control of stress is the central norepinephrine system. We investigated how dietary-induced binge eating alters central norepinephrine and related behaviors. Young male Sprague Dawley rats received calorie deprivation (24 h) and /or intermittent sweetened fat (vegetable shortening with sucrose; 30 min) twice a week for 10 weeks. The groups were Restrict Binge (calorie deprivation/sweetened fat), Binge (sweetened fat), Restrict (calorie deprivation), and Naive (no calorie deprivation/no sweetened fat). Dietary-induced binge eating was demonstrated by Restrict Binge and Binge, which showed an escalation in 30-min intake over time. Feeding suppression following nisoxetine (3 mg/kg; IP), a selective norepinephrine reuptake inhibitor, was not evident in Restrict Binge (Restrict Binge: 107±13, Binge: 52±9, Restrict: 80±8, Naive: 59±13% of saline injection at 1 h). In subsequent experiments with Restrict Binge and Naive, Restrict Binge had reduced corticosterone (Restrict Binge: 266±25; Naive: 494±36 ng/ml) and less feeding suppression (Restrict Binge: 81±12, Naive: 50±11% of non-restraint intake at 30 min) following restraint stress (1 h). Dietary-induced binge eating in Restrict Binge was not altered by a dorsal noradrenergic bundle lesion caused by N-(2-chloroethyl)-N-ethyl-2-bromobenzylamine (DSP4), but frontal cortex norepinephrine was positively correlated with the average 30-min intake post-lesion (0.69; p<0.01). In a separate set of animals, single-unit in vivo electrophysiological recording of locus coeruleus–norepinephrine neural activity demonstrated reduced sensory-evoked response as a consequence of the Restrict Binge schedule (Restrict Binge: 8.1±0.67, Naive: 11.9±1.09 Hz). These results, which suggest that a consequence of dietary-induced binge eating is to attenuate the responsiveness of the brain norepinephrine system, will further our understanding of how highly palatable foods dampen the stress neuraxis.

Abstract
OBJECTIVE Although there is a modest relation between obesity and depression, mechanisms that contribute to this co-occurrence are unclear. This study examined mood and eating behavior among obese adults with and without elevated depression symptoms. METHOD Obese adults (N = 50) were subtyped according to a Beck Depression Inventory (BDI) cutoff of 14, indicating "probable depression." Participants with (BDI ≥ 14; n = 15) and without (BDI < 14; n = 35) elevated depression symptoms were compared on affect- and eating-related variables measured via questionnaire and ecological momentary assessment (EMA) using ANCOVA and mixed model regression. RESULTS After adjusting for group differences in body mass index (BMI; p = .03), participants with elevated depression symptoms reported greater emotional eating via self-report questionnaire [F(1,50) = 4.3; p = .04], as well as more frequent binge eating (Wald χ(2) = 13.8; p < .001) and higher daily negative affect (Wald χ(2) = 7.7; p = .005) on EMA recordings. Emotional eating mediated the relationship between depression status and BMI (indirect effect estimate = 3.79; 95% CI = 1.02-7.46). DISCUSSION Emotional eating and binge eating were more commonly reported by obese adults with elevated depression symptoms compared to those without and may occur against a general backdrop of overall low mood. Intervention and prevention programs for obesity and/or depression should address disordered eating to prevent or minimize adverse health consequences.

Clinical characteristics and distinctiveness of DSM-5 eating disorder diagnoses: findings from a large naturalistic clinical database. J Eat Disord 2013; 1:31.

Abstract
BACKGROUND DSM-IV eating disorder (ED) diagnoses have been criticized for lack of clinical utility, diagnostic instability, and over-inclusiveness of the residual category "ED not otherwise specified" (EDNOS). Revisions made in DSM-5 attempt to generate a more scientifically valid and clinically relevant system of ED classification. The aim with the present study was to examine clinical characteristics and distinctiveness of the new DSM-5 ED diagnoses, especially concerning purging disorder (PD). METHODS Using a large naturalistic Swedish ED database, 2233 adult women were diagnosed using DSM-5. Initial and 1-year follow-up psychopathology data were analyzed. Measures included the Eating Disorder Examination Questionnaire, Structural Eating Disorder Interview, Clinical Impairment Assessment, Structural Analysis of Social Behavior, Comprehensive Psychiatric Rating Scale, and Structured Clinical Interview for DSM-IV Axis I Disorders. RESULTS Few meaningful differences emerged between anorexia nervosa binge/purge subtype (ANB/P), PD, and bulimia nervosa (BN). Unspecified Feeding and Eating Disorders (UFED) showed significantly less severity compared to other groups. CONCLUSIONS PD does not appear to constitute a distinct diagnosis, the distinction between atypical AN and PD requires clarification, and minimum inclusion criteria for UFED are needed. Further sub-classification is unlikely to improve clinical utility. Instead, better delineation of commonalities is important.

Abstract
Our first aim was to test whether a group cognitive-behavioral (CB) depression prevention program reduces substance use escalation over 2-year follow-up relative to two active comparison interventions and a brochure assessment control. Our second aim examined whether reductions in depressive symptoms mediate intervention effects, as posited by the affect-regulation model of substance use. In this indicated prevention trial, 341 high school adolescents at risk for depression because of the presence of elevated depressive symptoms were randomized to a Group CB intervention, group supportive-expressive group intervention, CB bibliotherapy, or educational brochure control condition. Participants in Group CB had significantly lower rates of substance use compared with brochure control participants at both 1- and 2-year follow-up and lower substance use at 2-year follow-up relative to bibliotherapy participants; no other condition differences were significant. Mediational analyses suggested that reductions in depressive symptoms from baseline to posttest accounted for changes in substance use over 2 years for participants in Group CB relative to brochure control participants but did not mediate effects relative to those receiving bibliotherapy. Results suggest that a secondary benefit of this CB group indicated depression prevention program is lower rates of long-term substance use. Findings supported the hypothesis that, relative to a nonactive comparison condition, reductions in depressive symptoms mediated the effects of Group CB prevention on substance use escalation.

Abstract
Previous research has found concurrent and prospective associations between negative mood and body dissatisfaction; however, only experimental research can establish causal relationships. This study utilized an experimental design to examine the influence of negative mood on body dissatisfaction. Undergraduate women were randomly assigned to an experimental or control condition. Participants in the experimental condition (n=21) completed a negative mood induction procedure. Participants in the control condition (n=24) completed a neutral mood procedure. All participants completed visual analog scales regarding their mood and satisfaction with weight and shape before and after each manipulation. Body dissatisfaction increased following the procedure for experimental but not control participants, suggesting that negative mood caused increased body dissatisfaction. In cultures that idealize thinness, body dissatisfaction may arise from funneling general feelings of dysphoria into more concrete and culturally meaningful negative feelings about the body.

Abstract
BACKGROUND Depression is common in young people, has a marked negative impact and is associated with self-harm and suicide. Preventing its onset would be an important advance in public health. OBJECTIVES To determine whether psychological or educational interventions, or both, are effective in preventing the onset of depressive disorder in children and adolescents. SEARCH METHODS The Cochrane Depression, Anxiety and Neurosis Review Group's trials registers (CCDANCTR) were searched at the editorial base in July 2010. Update searches of MEDLINE, EMBASE, PsycINFO and ERIC were conducted by the authors in September 2009. Conference abstracts, reference lists of included studies and reviews were searched and experts in the field contacted. SELECTION CRITERIA Randomised controlled trials of psychological or educational prevention programmes, or both, compared with placebo, any comparison intervention, or no intervention for young people aged 5 to 19 years-old, who did not currently meet diagnostic criteria for depression or who were below the clinical range on standardised, validated, and reliable rating scales of depression, or both, were included. DATA COLLECTION AND ANALYSIS Two authors independently assessed studies for inclusion and rated their quality. Sample sizes were adjusted to take account of cluster designs and multiple comparisons. We contacted study authors for additional information where needed. MAIN RESULTS Fifty-three studies including 14,406 participants were included in the analysis. There were only six studies with clear allocation concealment, participants and assessors were mostly not blind to the intervention or blinding was unclear so that the overall risk of bias was moderately high. Sixteen studies including 3240 participants reported outcomes on depressive diagnosis. The risk of having a depressive disorder post-intervention was reduced immediately compared with no intervention (15 studies; 3115 participants risk difference (RD) -0.09; 95% confidence interval (CI) -0.14 to -0.05; P<0.0003), at three to nine months (14 studies; 1842 participants; RD -0.11; 95% CI -0.16 to -0.06) and at 12 months (10 studies; 1750 participants; RD -0.06; 95% CI -0.11 to -0.01). There was no evidence for continued efficacy at 24 months (eight studies; 2084 participant; RD -0.01; 95% CI -0.04 to 0.03) but limited evidence of efficacy at 36 months (two studies; 464 participants; RD -0.10; 95% CI -0.19 to -0.02). There was significant heterogeneity in all these findings. There was no evidence of efficacy in the few studies that compared intervention with placebo or attention controls. AUTHORS' CONCLUSIONS There is some evidence from this review that targeted and universal depression prevention programmes may prevent the onset of depressive disorders compared with no intervention. However, allocation concealment is unclear in most studies, and there is heterogeneity in the findings. The persistence of findings suggests that this is real and not a placebo effect.

Abstract
OBJECTIVE Use classification tree analysis with lagged predictors to determine empirically derived cut-points for identifying adolescent girls at risk for future onset of threshold, subthreshold, and partial eating disorders and test for interactions between risk factors that may implicate qualitatively distinct risk pathways. METHOD Data were drawn from a prospective study of 496 adolescent girls who completed diagnostic interviews and surveys annually for 8 years. RESULTS Body dissatisfaction emerged as the most potent predictor; adolescent girls in the upper 24% of body dissatisfaction showed a 4.0-fold increased incidence of eating disorder onset (24% vs. 6%). Among participants in the high body dissatisfaction branch, those in the upper 32% of depressive symptoms showed a 2.9-fold increased incidence of onset (43% vs. 15%). Among participants in the low body dissatisfaction branch, those in the upper 12% of dieting showed a 3.6-fold increased incidence onset (18% vs. 5%). CONCLUSION This three-way interaction suggests a body dissatisfaction pathway to eating disorder onset that is amplified by depressive symptoms, as well as a pathway characterized by self-reported dieting among young women who are more satisfied with their bodies. It may be possible to increase the effectiveness of prevention programs by targeting each of these qualitatively distinct risk groups, rather than only individuals with a single risk factor.

Abstract
This study examined the influence of locus of control on disordered eating as mediated by the self-regulation of eating attitudes. The assessment instruments were adapted for athletes as the entire sample of 179 volunteer University students (M(age)=21.12; SD=2.87) were all regularly involved in competition. The results showed that (a) an internal locus of control had a positive influence on the self-regulation of eating attitudes in social interaction contexts; (b) self-regulatory eating attitudes had a negative influence on disordered eating in contexts of negative affect, social interaction, and lack of anticipation of consequences on performance; and (c) an internal locus of control had an influence on disordered eating through the mediation of self-regulatory eating attitudes in social interaction contexts, and an external locus of control attributed to the coach and sports friends had an influence on disordered eating through the mediation of self-regulatory eating attitudes in contexts of negative affect, social interaction and lack of anticipation of consequences on performance. This study, combined with an earlier study from Scoffier, Maïano, and d'Arripe-Longueville (2009) on the antecedents of athletes' eating disorders, suggests the powerful impact of the social environment on the development of disordered eating in athletes.

Abstract
Prospective studies have identified factors that increase risk for eating pathology onset, including perceived pressure for thinness, thin-ideal internalization, body dissatisfaction, dietary restraint, and negative affect. Research also suggests that body dissatisfaction and dietary restraint may constitute prodromal stages of the development of eating disorders. Prevention trials indicate that interventions that reduce pressure to be thin, thin-ideal internalization, body dissatisfaction, and negative affect significantly reduce eating disorder symptoms. Further, there is evidence that selective prevention programs that target young women at elevated risk for eating pathology by virtue of thin-ideal internalization, body dissatisfaction, and negative affect produce significant larger intervention effects than do universal programs offered to unselected populations. Thus, research on risk factors and prodromal stages of eating pathology has assisted in the design of efficacious prevention programs and the identification of high-risk individuals to target with these interventions; additional research in this area may lead to even more effective prevention programs.

Abstract
Several studies support the efficacy of interpersonal psychotherapy (IPT) in the treatment of eating disorders. Treatment outcomes are likely to be augmented through a greater understanding, and hence treatment targeting, of the mechanisms whereby IPT induces therapeutic gains. To this end, the present paper seeks to develop a theoretical model of IPT in the context of eating disorders (IPT-ED). After providing a brief description of IPT, the IPT-ED model is presented and research supporting its theorized mechanisms is summarized. This model proposes that negative social evaluation plays a pivotal role as both a cause (via its detrimental impact on self evaluation and associated affect) and consequence of eating disorder symptoms. In the final section, key eating disorder constructs (namely, the developmental period of adolescence, clinical perfectionism, cognitive dysfunction, and affect regulation) are re-interpreted from the standpoint of negative social evaluation thereby further explicating IPT's efficacy as an intervention for individuals with an eating disorder.

Abstract
The association between disordered eating and depression has been established, but less is known about the temporal relations between these two disturbances. Accordingly, the current study examined the reciprocal relations between depressive and bulimic symptoms over an 8-year period, with longitudinal data from a community sample of 496 female adolescents. Depressive symptoms predicted future increases in bulimic symptoms, and bulimic symptoms likewise predicted increases in depressive symptoms, controlling for earlier levels of symptoms for each outcome. These results provide evidence consistent with the hypothesis that the two disorders contribute reciprocally to each other, and indicate that successful prevention or treatment of one disorder may yield effects for the other. However, the relatively small predictive effect sizes imply that some third variable may contribute to both conditions (e.g., temperamental negative affectivity).

Abstract
This paper examines the relationship between emotions, depression and eating disorders. Initially, a review is undertaken of the current state of the research and clinical literature with regard to emotional factors in eating disorders. This literature is then integrated within a version of the multi-level model of emotion proposed by Power and Dalgleish. The aim of this paper is to incorporate a basic emotions, multi-modal perspective into developing a new emotions-based model that offers a theoretical understanding of psychological mechanisms in eating disorders. Within the new Schematic Propositional Analogical Associative Representation System model applied to eating disorders, it is argued that the emotions of anger and disgust are of importance in eating disorders and that the eating disorder itself operates as an inhibitor of emotions within the self. It is hoped that the development of a multi-levelled model of eating disorders will allow for the construction of number of specific testable hypotheses that are relevant to future research into the psychological treatment and understanding of eating disorders.

Abstract
BACKGROUND A specific manual-based form of cognitive behavioural therapy (CBT) has been developed for the treatment of bulimia nervosa (CBT-BN) and other common related syndromes such as binge eating disorder. Other psychotherapies and modifications of CBT are also used. OBJECTIVES To evaluate the efficacy of CBT, CBT-BN and other psychotherapies in the treatment of adults with bulimia nervosa or related syndromes of recurrent binge eating. SEARCH STRATEGY Handsearch of The International Journal of Eating Disorders since first issue; database searches of MEDLINE, EXTRAMED, EMBASE, PsycInfo, CURRENT CONTENTS, LILACS, SCISEARCH, CENTRAL and the The Cochrane Collaboration Depression, Anxiety & Neurosis Controlled Trials Register; citation list searching and personal approaches to authors were used. Search date June 2007. SELECTION CRITERIA Randomised controlled trials of psychotherapy for adults with bulimia nervosa, binge eating disorder and/or eating disorder not otherwise specified (EDNOS) of a bulimic type which applied a standardised outcome methodology and had less than 50% drop-out rate. DATA COLLECTION AND ANALYSIS Data were analysed using the Review Manager software program. Relative risks were calculated for binary outcome data. Standardised mean differences were calculated for continuous variable outcome data. A random effects model was applied. MAIN RESULTS 48 studies (n = 3054 participants) were included. The review supported the efficacy of CBT and particularly CBT-BN in the treatment of people with bulimia nervosa and also (but less strongly due to the small number of trials) related eating disorder syndromes.Other psychotherapies were also efficacious, particularly interpersonal psychotherapy in the longer-term. Self-help approaches that used highly structured CBT treatment manuals were promising. Exposure and Response Prevention did not enhance the efficacy of CBT.Psychotherapy alone is unlikely to reduce or change body weight in people with bulimia nervosa or similar eating disorders. AUTHORS' CONCLUSIONS There is a small body of evidence for the efficacy of CBT in bulimia nervosa and similar syndromes, but the quality of trials is very variable and sample sizes are often small. More and larger trials are needed, particularly for binge eating disorder and other EDNOS syndromes. There is a need to develop more efficacious therapies for those with both a weight and an eating disorder.

Abstract
In this meta-analytic review, the authors summarized the effects of depression prevention programs for youth as well as investigated participant, intervention, provider, and research design features associated with larger effects. They identified 47 trials that evaluated 32 prevention programs, producing 60 intervention effect sizes. The average effect for depressive symptoms from pre-to-posttreatment (r = .15) and pretreatment to-follow-up (r = .11) were small, but 13 (41%) prevention programs produced significant reductions in depressive symptoms and 4 (13%) produced significant reductions in risk for future depressive disorder onset relative to control groups. Larger effects emerged for programs targeting high-risk individuals, samples with more females, samples with older adolescents, programs with a shorter duration and with homework assignments, and programs delivered by professional interventionists. Intervention content (e.g., a focus on problem-solving training or reducing negative cognitions) and design features (e.g., use of random assignment and structured interviews) were unrelated to effect sizes. Results suggest that depression prevention efforts produce a higher yield if they incorporate factors associated with larger intervention effects (e.g., selective programs with a shorter duration that include homework).

Abstract
This study investigated a broad array of putative risk factors for the onset of major depression and examined their screening properties in a longitudinal study of 479 adolescent girls. Results indicated that the most potent predictors of major depression onset included subthreshold depressive symptoms, poor school and family functioning, low parental support, bulimic symptoms, and delinquency. Classification tree analysis revealed interactions between 4 of these predictors, suggesting qualitatively different pathways to major depression. Girls with the combination of elevated depressive symptoms and poor school functioning represented the highest risk group, with a 40% incidence of major depression during the ensuing 4-year period. Results suggest that selected and indicated prevention programs should target these high-risk populations and seek to reduce these risk factors.

Abstract
The current study investigated loss of control (LC) over eating and the role of anxiety, depression and emotional eating in a sample of both treatment seeking (N = 115) and non-treatment seeking (N = 73) overweight youngsters (aged 8-18) using a semi-structured clinical interview and self-report questionnaires. It was found that treatment seekers reported twice as much LC (40%) compared to non-treatment seekers (21%). Cross-sectional prediction models indicated that increased anxiety was associated with emotional eating and LC. Emotional eating tended to mediate the relationship between anxiety and LC. Increased depression was associated with emotional eating but not with LC. Especially overweight treatment seekers turn out to be at risk for LC. Because LC may develop as a result of inadequate coping with negative emotions like anxiety, obesity treatment should focus on teaching more effective coping strategies. Longitudinal research is recommended to further elaborate affect regulation and LC.

Abstract
This article reviews eating disorder (ED) prevention programs, highlighting features that define successful programs and particularly promising interventions, and how they might be further refined. The field of ED prevention has advanced considerably both theoretically and methodologically compared with the earlier ED prevention programs, which were largely psychoeducational and met with limited success. Recent meta-analytic findings show that more than half (51%) of ED prevention interventions reduced ED risk factors and more than a quarter (29%) reduced current or future eating pathology (EP). A couple of brief programs have been shown to reduce the risk for future onset of EP and obesity. Selected interactive, multisession programs offered to participants older than 15 years, delivered by professional interventionists and including body acceptance or dissonance-induction content, produced larger effects. Understanding and applying these results can help inform the design of more effective prevention programs in the future.

Abstract
OBJECTIVE Negative affect has been purported to play an important role in the etiology and maintenance of bulimic behaviors. The objective of this study was to identify daily mood patterns in the natural environment exhibited by individuals with bulimia nervosa and to examine the relationship between these patterns and bulimic behaviors. METHOD One hundred thirty-three women aged 18-55 meeting DSM-IV criteria for bulimia nervosa were recruited through clinical referrals and community advertisements. Ecological momentary assessment was used to collect multiple ratings of negative affect, binge eating and purging each day for a two-week period using palmtop computers. Latent growth mixture modeling was used to identify daily mood patterns. RESULTS Nine distinct daily mood patterns were identified. The highest rates of binge eating and purging episodes occurred on days characterized by stable high negative affect or increasing negative affect over the course of the day. CONCLUSIONS These findings support the conclusion that negative mood states are intimately tied to bulimic behaviors and may in fact precipitate such behavior.

Abstract
In this depression prevention trial, 341 high-risk adolescents (mean age = 15.6 years, SD = 1.2) with elevated depressive symptoms were randomized to a brief group cognitive-behavioral (CB) intervention, group supportive-expressive intervention, bibliotherapy, or assessment-only control condition. CB participants showed significantly greater reductions in depressive symptoms than did supportive-expressive, bibliotherapy, and assessment-only participants at posttest, though only the difference compared with assessment controls was significant at 6-month follow-up. CB participants showed significantly greater improvements in social adjustment and reductions in substance use at posttest and 6-month follow-up than did participants in all 3 other conditions. Supportive-expressive and bibliotherapy participants showed greater reductions in depressive symptoms than did assessment-only controls at certain follow-up assessments but produced no effects for social adjustment and substance use. CB, supportive-expressive, and bibliotherapy participants showed a significantly lower risk for major depression onset over the 6-month follow-up than did assessment-only controls. The evidence that this brief CB intervention reduced risk for future depression onset and outperformed alternative interventions for certain ecologically important outcomes suggests that this intervention may have clinical utility.

Abstract
The limited efficacy of prior eating disorder (ED) prevention programs led to the development of dissonance-based interventions (DBIs) that utilize dissonance-based persuasion principles from social psychology. Although DBIs have been used to change other attitudes and behaviors, only recently have they been applied to ED prevention. This article reviews the theoretical rationale and empirical support for this type of prevention program. Relative to assessment-only controls, DBIs have produced greater reductions in ED risk factors, ED symptoms, future risk for onset of threshold or subthreshold EDs, future risk for obesity onset, and mental health utilization, with some effects persisting through 3-year follow-up. DBIs have also produced significantly stronger effects than alternative interventions for many of these outcomes, though these effects typically fade more quickly. A meta-analysis indicated that the average effects for DBIs were significantly stronger than those for non-DBI ED prevention programs that have been evaluated. DBIs have produced effects when delivered to high-risk samples and unselected samples, as well as in efficacy and effectiveness trials conducted by six independent labs, suggesting that the effects are robust and that DBIs should be considered for the prevention of other problems, such as smoking, substance abuse, HIV, and diabetes care.

Abstract
OBJECTIVE To revisit the merits and problems inherent in considering obesity, or some aspect of obesity, as a mental or behavioral disorder. METHOD The author suggests shifting the focus from the state of obesity to the process of nonhomeostatic overeating that results in obesity. Studies are reviewed that pertain to various models of nonnormative overeating including eating disorder models that stress the form of overeating, substance use disorder models focusing on its consequences, and affect regulation or stress response models focusing on its function. RESULTS Studies focusing on abnormal eating patterns, including binge eating and night eating suggest that such patterns may be related to the development of obesity. While the literature pertaining to substance use and other models of nonhomeostatic overeating is beginning to mount, current evidence is mostly preliminary and indirect. CONCLUSION An attempt to devise diagnostic criteria based on the above models raises multiple difficulties, since the phenomena central to each model are dimensional, common, and variably associated with distress or dysfunction. A detailed understanding of the neurobiological relationships among eating behavior, reward systems, and affect regulation systems will enable a more meaningful consideration of these models and will facilitate specific treatment for disorders of overeating.

Abstract
OBJECTIVE This study examined a broad range of childhood risk factors for binge-eating disorders (bulimia nervosa or binge eating disorder, BN/BED), utilizing data that had been collected prospectively in the 10-year National Heart, Lung, and Blood Institute Growth and Health Study. METHOD Forty-five women with a history of BED/BN (with onset age > 14 and <20 years) and 1,515 women who did not have a history of an eating disorder were included. RESULTS Signal detection analysis indicated a single pathway that identified approximately 13% of the BED/BN cases. The pathway was based on an elevated level of perceived stress prior to the age of 14. CONCLUSION Our findings suggest that eating disorders may have multiple and complex etiologies. This is the first study to suggest that elevated levels of perceived stress may precede the onset of binge-eating disorders. Whether this is a causal association remains a question.

Abstract
This meta-analytic review found that 51% of eating disorder prevention programs reduced eating disorder risk factors and 29% reduced current or future eating pathology. Larger effects occurred for programs that were selected (versus universal), interactive (versus didactic), multisession (versus single session), solely offered to females (versus both sexes), offered to participants over 15 years of age (versus younger ones), and delivered by professional interventionists (versus endogenous providers). Programs with body acceptance and dissonance-induction content and without psychoeducational content and programs evaluated in trials using validated measures and a shorter follow-up period also produced larger effects. Results identify promising programs and delineate sample, format, and design features associated with larger effects, which may inform the design of more effective prevention programs in the future.
