Abstract
PURPOSE To evaluate compulsive exercise, researchers often rely on the widely used Compulsive Exercise Test (CET). However, the measure has shown unstable factor structure in several validation studies and is not available in Portuguese for use in Brazil. We aimed to describe the translation and cultural adaptation of the CET to Brazilian Portuguese, to test several factor structures among Brazilian and US samples of men and women, to test measurement invariance across countries, and to evaluate its internal consistency. Furthermore, we sought to evaluate convergent validity, correlating the CET with a measure of eating disorder symptoms, and to compare compulsive exercise symptoms between countries. METHODS Four models of the latent structure of the CET were tested using confirmatory factor analyses (CFAs), three-factor structure with 15 items, three-factor structure with 18 items, four-factor structure with 21 items, and the original five-factor structure with 24 items, in a sample of 1,531 young adults (601 Brazilians and 930 Americans), aged 18-35 years. RESULTS A series of CFAs demonstrated that the three-factor structure with 15 items showed a better fit to the data. This model demonstrated good convergent validity and internal consistency. Results from the CET multigroup CFA showed evidence for the invariance at the configural, metric, and scalar levels across Brazilians and Americans. Furthermore, significant differences were found between Brazilians and Americans, with Brazilians demonstrating higher scores on the Avoidance and rule-driven behavior and Mood improvement subscales, whereas US participants scored higher on the Weight control exercise subscale. CONCLUSIONS Results support the three-factor structure with 15 items to be used as a measure of compulsive exercise among Brazilians and Americans, allowing cross-cultural comparisons between these countries.

Abstract
INTRODUCTION Compulsive exercise is a transdiagnostic feature of eating disorders which adversely affects aspects of recovery, such as length of hospitalisation, risk of a chronic outcome, and risk of relapse. CompuLsive Exercise Activity TheraPy (LEAP) aims to reduce compulsive exercise through a cognitive behavioural approach. This study aims to investigate the effect of LEAP on compulsive exercise behaviour using subscales of the Compulsive Exercise Test (CET), a measure of exercise in individuals with eating disorders. Predictive validity of the CET's subscales and its ability to predict eating psychopathology are investigated. METHOD This study used data from a randomized controlled trial of LEAP (1). Linear mixed modelling was used to investigate the effect of LEAP on compulsive exercise behaviour, and the predictive ability of CET subscales on various outcomes. The CET was compared to other exercise measures to assess its superiority in predicting eating psychopathology. RESULTS LEAP was superior in reducing the scores of the CET's Avoidance and Rule Driven Behaviour and Exercise Rigidity subscales. All subscales made a contribution to the respective models. The CET was superior to other measures in predicting eating pathology. CONCLUSION The results lend credibility to LEAP's ability to reduce core parts of compulsive exercise. The CET has been found to target important aspects of compulsive exercise behaviour, and has was superior to other exercise measures in predicting eating psychopathology.

Abstract
Eating disorders (ED) have frequently been described among athletes. However, their specific features and therapy responses are lacking in the literature. The aims of this article were to compare clinical, psychopathological and personality traits between ED patients who were professional athletes (ED-A) with those who were not (ED-NA) and to explore differences in response to treatment. The sample comprised n = 104 patients with ED (n = 52 ED-A and n = 52 matched ED-NA) diagnosed according to DSM-5 criteria. Evaluation consisted of a semi-structured face-to-face clinical interview conducted by expert clinicians and a psychometric battery. Treatment outcome was evaluated when the treatment program ended. ED-A patients showed less body dissatisfaction and psychological distress. No differences were found in treatment outcome among the groups. Within the ED-A group, those participants who performed individual sport activities and aesthetic sports presented higher eating psychopathology, more general psychopathology, differential personality traits and poor therapy outcome. Individual and aesthetic sports presented more severity and worse prognosis. Although usual treatment for ED might be similarly effective in ED-A and ED-NA, it might be important to develop preventive and early detection programs involving sports physicians and psychologists, coaches and family throughout the entire athletic career and afterwards.

Abstract
OBJECTIVES Better understanding of compulsive exercise is needed in sports medicine. Whilst compulsive exercise may impact mental health, the limited research exploring the relationship between compulsive exercise and psychosocial outcomes is equivocal. The majority of studies have examined eating disorder populations where the eating disorder pathology might account for distress. This study explores relationships between compulsive exercise and mental health. DESIGN Cross-sectional observational study. METHODS Australian recreational exercisers and athletes (N = 1157; Mage 36.4, standard deviation = 12.9, 77 % female) recruited through sporting organisations, clubs, and gyms, completed measures of compulsive exercise, depression, anxiety, stress, life satisfaction, social physique anxiety, and self-esteem. Regression analyses examined relationships between dimensions of compulsive exercise and wellbeing. RESULTS After adjustment for eating disorder symptoms and sporting level, compulsive exercise was associated with increased risk of clinically-significant anxiety, depression, and stress symptoms. Compulsive exercise was also associated with lower life satisfaction and self-esteem, and higher social physique anxiety. Notably, different dimensions of compulsive exercise had varying relationships with outcomes, and avoidance and rule-driven behaviour and lack of exercise enjoyment were associated with poorer mental health and wellbeing. CONCLUSIONS Results suggest that compulsive exercise is uniquely associated with a range of psychosocial and mental health outcomes. Results support the need to improve identification and treatment of compulsive exercise in sport and exercise settings. Results highlight that mental health intervention is an important component of treatment, and treatments targeting symptoms related to avoidance and rule-driven behaviour, and anhedonia may be valuable treatment components for those with compulsive exercise.

Abstract
BACKGROUND AND OBJECTIVES The role of anxiety as a risk factor for compulsive exercise elements among adolescents is unclear. Intolerance of uncertainty (IU), which is a risk feature for anxiety and eating disorders, may be an important, unexplored risk factor for compulsive exercise dimensions. This study aimed to examine the role of IU dimensions and anxiety on compulsive exercise elements. Given previous evidence indicating gender differences in compulsive exercise and IU levels, gender was included as a moderator. DESIGN/METHODS A total of 201 adolescent girls and 207 adolescent boys completed the following questionnaires: Eating Disorder Inventory-3, Intolerance of Uncertainty Scale-12 (IUS-12), a brief version of the State-Trait Anxiety Inventory and the Compulsive Exercise Test (CET). RESULTS The hierarchical regression analyses showed that the interaction between IUS-Prospective and gender emerged as a significant predictor of CET-Avoidance and CET-Weight control exercise beyond symptoms of eating disorders and anxiety. Post hoc analysis revealed that the IUS-Prospective was a significant predictor of CET-Avoidance and CET-Weight Control among boys, but not among girls. CONCLUSIONS These findings suggest that prospective IU may contribute towards obsessive-compulsive attitudes towards exercise among adolescent population, specifically among boys.

Abstract
BACKGROUND Compulsive exercise (CE) has been proposed as one of the maladaptive elements that might concur to developing and maintaining an eating disorder (ED), even if no conclusive consensus is yet available. This study evaluates the psychometric properties of the Compulsive Exercise Test (CET), the questionnaire most frequently discussed in the literature. Our second aim is to evaluate the relationships between CE, quality of life, and different body concerns in a group of individuals. METHODS Two different studies are performed. In the first study, we evaluate the psychometric properties of the Italian CET with a sample of 272 individuals (157 with different diagnoses of ED). In the second study, a group of 75 ED patients is compared to 68 of their peers looking for specific differences and relationships between CE, quality of life, and body concerns. RESULTS The CET shows optimal psychometric proprieties, and a five-factors structure. CE is linked to more severe specific psychopathology in ED patients, including increased thoughts of restraint and concerns about weight and shape. Moreover, weight phobia and quality of life are predictors of CE in patients. CONCLUSION The specific role of CE is discussed according to its connections with a core psychopathological element like weight phobia. Specific profiles of CE emerged for each clinical subgroup, and they corroborate the presence of different cognitive/physical approach to exercise. The CE showed to be a dysfunctional element with a disruptive role in patients' quality of life. Future directions and possible applications of the CET are also discussed.

Abstract
Introduction: Body image distortion is a core symptom of anorexia nervosa (AN), embodying dissatisfaction and overvaluation of body appearance and weight. Body image distortion is an important factor in the maintenance of weight loss behaviours such as compulsive physical exercise. Conversely, physical exercise seems to have an aggravating effect on body image in patients with AN, but the evidence is still poor. The aim of this study was to examine the relationship between body image distortion and physical exercise in AN in order to understand whether physical exercise may play a specific role in body image distortion beyond psychopathological severity. Methods: Forty patients with AN and 21 healthy controls were tested for body image distortion and different proxies of physical exercise. Univariate correlations tested the relationship between body image distortion and physical exercise in AN and control groups. Then, to experimentally assess the effect of exercise on body image distortion, participants were invited to rate their body image before and after a standardised effort test. Results: In the AN group, a correlation was found between physical activity and body image distortion (p < 0.01), which was still significant after controlling for psychopathological severity. No correlation was found in healthy controls. After a standardised effort, patients with AN had higher increases in body image distortion than healthy controls (almost 4 kg/m2 vs. 0.8 kg/m2) (p < 0.01). Discussion: Physical exercise may contribute to the distortion of body image in anorexia nervosa and explain the paradoxical augmentation of unhealthy exercise despite ongoing weight loss.

Abstract
BACKGROUND Exercise is a prominent feature of most eating disorders, and has been shown to have a number of detrimental effects on treatment outcome. There is some disagreement in the literature regarding the construct of compulsive exercise, and assessment and treatment varies significantly. This study therefore aimed to aggregate expert clinicians' and researchers' views on how to define and measure compulsive exercise in eating disorder patients. The expert panel was also asked about questionnaire design, and possible problems when measuring compulsive exercise. METHOD This study used the Delphi method to establish consensus amongst an expert panel. Three successive rounds of questionnaires were distributed to the panel over a period of six months. The first round consisted of four open-ended questions regarding the definition and measurement of compulsive exercise in eating disorder patients. For Round 2, 70 statements were derived from the answers, and panelists were asked to rate each item on a Likert-based scale. An 85% consensus level was chosen. In Round 3, 44 statements were re-rated by the panel. RESULTS Seventeen of 24 participants completed all three rounds of the study. Consensus was achieved for 63% of the items, while 18.5% reached near consensus, and 18.5% did not reach consensus after Round 3. The panel agreed on a number of important aspects of compulsive exercise. Several suggestions regarding the format of a questionnaire assessing this behavior were also endorsed. The panel further identified common difficulties when assessing compulsive exercise in eating disorder patients, notably a lack of consensus still apparent in the literature. CONCLUSION The current findings constitute a further step towards a unified definition of compulsive exercise, and contribute important suggestions to the measurement of this behavior.

Abstract
Background and aims Problematic exercise (PE) has mainly been assessed with self-report instruments. However, summarized evidence on the reliability of the scores derived from such instruments has yet to be provided. The present study reports a reliability generalization meta-analysis of six well-known self-report measures of PE (Commitment to Exercise Scale, Compulsive Exercise Test, Exercise Addiction Inventory, Exercise Dependence Questionnaire, Exercise Dependence Scale, and Obligatory Exercise Questionnaire). Methods Pooled effect sizes were computed using a random-effect model employing a restricted maximum likelihood estimation method. Univariable and multivariable meta-regressions analyses were employed for testing moderator variables. Results Data retrieved from 255 studies (741 independent samples, N = 254,174) identified three main groups of findings: (i) pooled alpha values that, ranging from 0.768 to 0.930 for global scores and from 0.615 to 0.907 for subscale scores, were found to be sensitive to sociodemographic and methodological characteristics; (ii) reliability induction rates of 47.58%; and (iii) the virtually non-existent testing of the assumptions required for the proper applicability of alpha. Data unavailability prevented the provision of summarized reliability estimates in terms of temporal stability. Discussion These findings highlight the need to improve reliability reporting of the scores of self-reported instruments of PE in primary studies. This implies providing both prior justification for the appropriateness of the index employed and reliability data for all the subpopulation of interest. The values presented could be used as a reference both for comparisons with those obtained in future primary studies and for correcting measurement-related artefacts in quantitative meta-analytic research concerning PE.

Abstract
OBJECTIVE The Compulsive Exercise Test (CET) was developed to assess compulsive exercise in patients with eating disorders (EDs), but originally validated in a nonclinical sample, and psychometric properties were only investigated in small clinical samples. Therefore, the aim of this study was to examine its psychometric properties in a large clinical sample of adolescent and adult inpatients with anorexia nervosa and bulimia nervosa. METHOD A sample of 2,535 German female inpatients with EDs completed the CET and other instruments at admission and discharge. Factor structure (confirmatory [CFA] and exploratory factor analyses [EFA]), internal consistency and construct validity, measurement invariance across age and diagnostic groups, group comparisons of means, as well as sensitivity to change during treatment were assessed. RESULTS The CET showed high internal consistency, very good construct validity, and sensitivity to change. CFA indicated a better fit of four-factor and three-factor solutions compared to the original five-factor model. However, subsequent EFA identified an optimum for a five-factor model. Only three subscales were satisfactorily invariant to measurement, but not the CET total score. Only small differences in scores between patient groups were observed. DISCUSSION Results support internal consistency, construct validity, and sensitivity to change, whereas factor structure remains inconclusive, questioning the theoretical basis of the CET. There is limited support for using the lack of enjoyment subscale, and only moderate support for using the rigidity subscale in patients with EDs. It is recommended to further explore and/or revise the original CET, including investigation in other samples, for example, male samples.

Abstract
Background Previous theoretical models and reviews have documented a strong connection between emotion dysregulation eating disorder (ED) psychopathology among the general and clinical populations. The aim of this review was to build on this previous work by conducting a network meta-analysis to explore associations between adaptive and maladaptive emotion regulation strategies and ED psychopathology trans-diagnostically across the ED spectrum to identify areas of emotion dysregulation that have the strongest association with symptomatology. Methodology A total of 104 studies were included in the meta-analysis and correlation coefficient representing the associations between specific emotion regulation strategies and ED symptomatology were extracted. We ran a Bayesian random effects network meta-analysis and the initial network was well-connected with each emotion regulation strategy being linked to at least one other strategy. We also conducted a network meta-regression to explore whether between-study differences in body mass index (BMI), age, and whether the sample consisted of solely female participants explained any possible network inconsistency. Results The network meta-analysis revealed that ruminations and non-acceptance of emotions were most closely associated with ED psychopathology. There was no significant network inconsistency but two comparisons approached significance and thus meta-regressions were conducted. The meta-regressions revealed a significant effect of BMI such that the associations between different emotion regulation strategies and ED symptomatology were weaker among those with low BMI. Discussion The present findings build on previous work and highlight the role of rumination and difficulties with accepting emotions as key emotion regulation difficulties in EDs. Additionally, the finding that the associations were weaker among ED patients with low BMI may point toward a complex relationship between ED behaviors and emotion regulation. Taken together, our findings call for interventions that target emotion regulation, specifically rumination and difficulties accepting emotions, in the treatment of EDs.

Abstract
The rising prevalence of gambling disorder (GD) among women has awakened considerable interest in the study of therapeutic outcomes in females. This study aimed to explore profiles of women seeking treatment for GD based on a set of indicators including sociodemographic features, personality traits, clinical state at baseline, and cognitive behavioral therapy (CBT) outcomes. Two-step clustering, an agglomerative hierarchical classification system, was applied to a sample of n = 163 women of ages ranging from 20 to 73 years-old, consecutively attended to by a clinical unit specialized in the treatment of G. Three mutually exclusive clusters were identified. Cluster C1 (n = 67, 41.1%) included the highest proportion of married, occupationally active patients within the highest social status index. This cluster was characterized by medium GD severity levels, the best psychopathological functioning, and the highest mean in the self-directedness trait. C1 registered 0% dropouts and only 14.9% relapse. Cluster C2 (n = 63; 38.7%) was characterized by the lowest GD severity, medium scores for psychopathological measures and a high risk of dropout during CBT. Cluster C3 (n = 33; 20.2%) registered the highest GD severity, the worst psychopathological state, the lowest self-directedness level and the highest harm-avoidance level, as well as the highest risk of relapse. These results provide new evidence regarding the heterogeneity of women diagnosed with GD and treated with CBT, based on the profile at pre- and post-treatment. Person-centered treatments should include specific strategies aimed at increasing self-esteem, emotional regulation capacities and self-control of GD women.

[PMID: 34959896 PMCID: PMC8708838 DOI: 10.3390/nu13124344] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2021] [Revised: 11/29/2021] [Accepted: 12/01/2021] [Indexed: 11/17/2022] Open
Abstract
Current studies show an increase in the risk of eating disorders in runners. Since it is known that abusive exercise can be both a cause and a consequence of such developments, the main objective of the present study was to examine the risk and possible relationships between negative running addiction (NRA), as measured by the reduced and validated SAS-40 scale, and the tendency to be a compulsive eater (measured by YFAS 2.0), anorexia nervosa (AN), and/or bulimia nervosa (BN) (measured by EAT-40). This study highlights the novelty of researching the level of influence of NRA on each defined eating disorder. METHOD A total of 167 Spanish-speaking federated runners in cross-country and track running (42% women and 58% men), with an average age of 24 years and an average BMI of 21 kg/m2, responded to an online questionnaire that asked about sociodemographic data and the Spanish versions of the SAS-40, YFAS 2, YFAS 3, and YFAS 4. Through a quantitative methodology using logistic regressions-the coefficient of determination and Pearson's correlation coefficient-we created a sample analysis that related the significant items of the DSM-V to the results of the questionnaires administered, as well as their relationship with the practice of the sport in question and various variables of the environment. RESULTS The rates of CE, AN, and BN were 65, 11.4, and 16.2%, respectively. The tendency towards CE increased with a lower weight (r = 0.156, p < 0.05), not having been overweight in childhood (r = 0.151, p < 0.05), and being a long-distance runner (r = 0.123 p < 0.05). The risk of AN increased with the absence of menstruation for more than 3 months (r = 0.271 p < 0.01), having suffered from childhood obesity (r = 0.213 p < 0.05), and being underweight (r = 0.064 p < 0.05). The risk of BN increased with having suffered from childhood obesity (r = 0.194 p < 0.05), having a higher weight (r = 0.140, p < 0.05), and practicing athletics, especially the relay modality (r = 0.044 p < 0.05). CONCLUSIONS A considerable number of runners are at risk of suffering from some type of eating disorder. A significant relationship was observed between long-distance runners and the risk of eating disorders (AN, BN, and CE), and the association is stronger for CE than for AN and BN. Lastly, childhood experiences (such as being obese/a healthy weight) were notorious for increasing the risk of eating disorders. Further studies are needed to research each particular parameter and the relationships between the possible levels of dependence on exercise. LEVEL OF EVIDENCE Level III, cohort analytic study.

Emotion Dysregulation as a Mediator of the Relationship between Anxiety, Compulsive Exercise and Eating Disorder Symptoms in Adolescents. CHILDREN 2021; 8:children8121088. [PMID: 34943286 PMCID: PMC8700564 DOI: 10.3390/children8121088] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/31/2021] [Revised: 11/16/2021] [Accepted: 11/20/2021] [Indexed: 11/17/2022]
Abstract
Anxiety has been suggested to be a key contributing factor for compulsive exercise, however, existing literature has demonstrated contradictory relationships between anxiety and compulsive exercise among adolescents. According to the Emotional Cascade Model (ECM), factors such as rumination and emotional suppression may mediate the association between affect and exercise. The current study therefore aimed to investigate whether rumination and emotional suppression mediate the relationship between anxiety and compulsive exercise in predicting ED symptoms in adolescents. Questionnaires assessing compulsive exercise, anxiety, depressive rumination, emotional suppression, and ED symptoms were completed by 212 adolescent males (Mage = 13.39, SD = 1.22) and 189 adolescent females (Mage = 13.64, SD = 1.29). The structural equation model showed indirect effects between anxiety and compulsive exercise through rumination and emotional suppression in males but not in females. Moreover, anxiety had an indirect effect on eating disorder symptoms through rumination, emotional suppression and compulsive exercise in both males and females. In line with ECM, the results suggest that rumination and emotional suppression may have a key role in the association between anxiety, compulsive exercise and eating disorder symptoms in adolescents. These findings suggest that compulsive exercise may be used as a dysfunctional coping mechanism to escape from a negative emotional cascade generated by the interaction of anxiety, rumination and emotional suppression. Future longitudinal studies to test the role of compulsive exercise as a dysfunctional behaviour in the ECM are needed.

Abstract
AbstractExercise addiction (EA) affects a considerable number of individuals who regularly perform exercise-sport activities. The co-occurrence of EA manifestations and the continuum of disordered eating-eating disorders (EDs) is so common in sports that a deeper understanding of them as comorbidities is warranted. The aim of this review is to provide an up-to-date overview and synthesis of the research on the relationship between maladaptive exercise and dysfunctional eating in the sport context. A systematic review was conducted following the PRISMA guidelines. A total of 22 empirical studies (23 articles) with young and adult female and male athletes from several sports and competition levels was included. EA in conjunction with eating disturbances is frequent among athletes, yet the prevalence rates are inconsistent. Existing evidence suggests that EA is a relevant outcome of ED pathology among athletes, supporting the classical secondary type of EA. However, research also reveals that excessive exercising plays a central role in the psychopathology of disordered eating. There is a need for further quantitative research addressing the features and correlates of the EA-EDs dyad, qualitative research on the subjective experiences of athletes with disordered exercise and eating, longitudinal and experimental research to establish possible causal paths and attempts to develop comprehensive conceptual models of EA and its co-occurrence with EDs, in order to improve the identification, prevention, and management of this dyadic condition in the sport context.

Abstract
BACKGROUND Exercise addiction is associated with multiple adverse outcomes and can be classified as co-occurring with an eating disorder, or a primary condition with no indication of eating disorders. We conducted a meta-analysis exploring the prevalence of exercise addiction in adults with and without indicated eating disorders. METHODS A systematic review of major databases and grey literature was undertaken from inception to 30/04/2019. Studies reporting prevalence of exercise addiction with and without indicated eating disorders in adults were identified. A random effect meta-analysis was undertaken, calculating odds ratios for exercise addiction with versus without indicated eating disorders. RESULTS Nine studies with a total sample of 2140 participants (mean age = 25.06; 70.6% female) were included. Within these, 1732 participants did not show indicated eating disorders (mean age = 26.4; 63.0% female) and 408 had indicated eating disorders (mean age = 23.46; 79.2% female). The odds ratio for exercise addiction in populations with versus without indicated eating disorders was 3.71 (95% CI 2.00-6.89; I2 = 81; p ≤ 0.001). Exercise addiction prevalence in both populations differed according to the measurement instrument used. DISCUSSION Exercise addiction occurs more than three and a half times as often as a comorbidity to an eating disorder than in people without an indicated eating disorder. The creation of a measurement tool able to identify exercise addiction risk in both populations would benefit researchers and practitioners by easily classifying samples.

Abstract
Unhealthy exercise is a core symptom of eating disorders that predicts greater chronicity and risk of relapse. A detailed conceptualization of unhealthy exercise in the context of eating disorders is only beginning to emerge, and associations between specific dimensions of unhealthy exercise and eating disorder symptoms have received little attention. The aim of the current study was to examine associations between three key dimensions of unhealthy exercise - compulsive exercise (i.e., rule-driven exercise to avoid negative affect), exercise to control weight/shape, and exercise to compensate for recent food intake - with restrictive eating and binge eating. Participants were 239 women drawn from two separate studies of emotions and eating behavior; 126 (52.7%) endorsed restrictive eating and/or objective binge eating episodes in the past three months. Unhealthy exercise dimensions were measured using the Compulsive Exercise Test and investigator-designed items, and eating disorder symptoms were assessed using the Eating Pathology Symptoms Inventory. Restrictive eating was only associated with avoidance and rule-driven exercise, whereas binge eating was significantly correlated with all unhealthy exercise variables. Multiple regression results revealed that only compensatory exercise was uniquely associated with binge eating. Unhealthy exercise consists of partially distinct dimensions with differential relations to core eating disorder symptoms. Future research should examine unhealthy exercise dimensions in patients with eating disorder diagnoses and consider whether treatments for specific unhealthy exercise forms might be beneficial.

Abstract
BACKGROUND AND AIMS This study examined the relationship between self-reported symptoms of morbid exercise behaviour (MEB) and eating disorders (ED) using meta-analytic techniques. METHODS We systematically searched MEDLINE, PsycINFO, Web of Science, SciELO and Scopus. Random effects models were used to compute pooled effect sizes estimates (r). The robustness of the summarized estimates was examined through sensitivity analyses by removing studies one at a time. RESULTS Sixty-six studies comprising 135 effect-sizes (N = 21,816) were included. The results revealed: (a) small-sized relationship in the case of bulimic symptoms (r = 0.19), (b) small- (r = 0.28) to medium-sized relationships (r = 0.41) in the case of body/eating concerns, and (c) medium-sized relationships in the case of overall ED symptoms (r = 0.35) and dietary restraint (r = 0.42). Larger effect sizes were observed in the case of overall ED symptoms in clinical, younger, and thinner populations, as well as when employing a continuously-scored instrument for assessing ED or the Compulsive Exercise Test for assessing MEB. Larger effect sizes were also found in female samples when the ED outcome was dietary restraint. CONCLUSIONS The identified gaps in the literature suggest that future research on the topic may benefit from: (a) considering a range of clinical (in terms of diagnosed ED) and non-clinical populations from diverse exercise modalities, (b) addressing a wide range of ED symptomatology, and (c) employing longitudinal designs that clarify the temporal direction of the relationship under consideration.

Abstract
BACKGROUND Research has identified factors specific to exercise in eating disorder patients such as affect regulation and compulsivity. Existing measures of exercise behaviour which were not originally designed for eating disorder patients may not adequately assess these factors. The aim of this systematic review is to identify and assess the psychometric properties of all self-report measures of exercise designed to be used with eating disorder patients. METHOD A systematic review was conducted following the PRISMA guidelines. MedLine, Scopus and PsycINFO were systematically searched. A total of 12 studies examining two measures, the Exercise and Eating Disorders and the Compulsive Exercise Test, met inclusion criteria. RESULTS Validation studies showed promising results for both tests and established internal consistency, concurrent and convergent validity, and construct validity. The factor structure of the Compulsive Exercise Test was not confirmed in the majority of the studies included in this review, while there are only two studies conducting factor analysis on the Exercise and Eating Disorders. CONCLUSION The two measures identified by this systematic review represent the current research on measures of compulsive exercise for eating disorder patients. Further research is needed to confirm a factor structure and validate both the Compulsive Exercise Test and the Exercise and Eating Disorders in more diverse clinical samples.

Abstract
Objectives The objectives of this study were to (1) validate the Norwegian version of the Compulsive Exercise Test (CET) in adults with longstanding eating disorders, and (2) explore predictors of high CET-score. Methods: Adult inpatients (n = 166) with longstanding DSM-IV Anorexia Nervosa, Bulimia Nervosa (BN) or Eating Disorder not Otherwise Specified (EDNOS) completed the CET instrument, Eating Disorder examination questionnaire (EDE-Q), Beck Depression Inventory-II (BDI-II) and Symptom checklist-90 (SCL-90). A total CET score of 15 or above was defined as high CET-score. ANOVA, Confirmatory factor analysis, Pearson’s correlation, and logistic regression were used to analyze the data. Results Cronbach’s alpha varied from 0.68 to 0.96 for the CET and its subscales. The confirmatory factor analysis showed adequate fit. Convergent validity of the CET demonstrated correlation between EDE-Q global and subscale scores and CET total score. The same pattern was found for correlation between CET subscales and EDE-Q subscales. EDE-Q global score and frequency of exercise episodes predicted high CET-score, yet 21% of the patients with high CET score had less than one episode of exercise per week. Conclusion The Norwegian version of CET is valid and useful for assessing compulsive exercise in a sample with longstanding ED. The understanding of compulsive exercise must to a greater extent differ between obsessions and compulsions, as a significant number of patients with high CET score showed no or little exercise behavior.

Abstract
BACKGROUND Compulsive exercise (CE) is a frequent symptom in patients with eating disorders (EDs). It includes, in addition to quantitatively excessive exercise behaviour, a driven aspect and specific motives of exercise. CE is generally associated with worse therapy outcomes. The aims of the study were to compare self-reported quantity of exercise, compulsiveness of exercise as well as motives for exercise between patients with anorexia nervosa (AN), bulimia nervosa (BN) and healthy controls (HC). Additionally, we wanted to explore predictors of compulsive exercise (CE) in each group. METHODS We investigated 335 female participants (n = 226 inpatients, n = 109 HC) and assessed self-reported quantity of exercise, compulsiveness of exercise (Compulsive Exercise Test), motives for exercise (Exercise Motivations Inventory-2), ED symptoms (Eating Disorder Inventory-2), obsessive-compulsiveness (Obsessive-Compulsive Inventory-Revised), general psychopathology (Brief Symptom Inventory-18) and depression (Beck Depression Inventory-2). RESULTS Both patients with AN and BN exercised significantly more hours per week and showed significantly higher CE than HC; no differences were found between patients with AN and BN. Patients with EDs and HC also partly varied in motives for exercise. Specific motives were enjoyment, challenge, recognition and weight management in patients with EDs in contrast to ill-health avoidance and affiliation in HC. Patients with AN and BN only differed in regard to exercise for appearance reasons in which patients with BN scored higher. The most relevant predictor of CE across groups was exercise for weight and shape reasons. CONCLUSIONS Exercise behaviours and motives differ between patients with EDs and HC. CE was pronounced in both patients with AN and BN. Therefore, future research should focus not only on CE in patients with AN, but also on CE in patients with BN. Similarities in CE in patients with AN and BN support a transdiagnostic approach during the development of interventions specifically targeting CE in patients with EDs.

Abstract
The present study assessed the suitability of the Compulsive Exercise Test (athlete version; CET-A) for identifying female athletes with clinically significant features related to or comparable with eating psychopathology. Three hundred and sixty-one female athletes (including 12 with a clinically diagnosed eating disorder) completed the Eating Disorders Examination Questionnaire and the CET-A. Receiver operating curve analysis was employed to identify a cut-off value on the CET-A, which could indicate clinically significant features related to or comparable with eating psychopathology among female athletes. The analysis demonstrated that a CET-A score of 10 successfully discriminated female athletes with a current eating disorder. The results suggest that the CET-A may be a suitable tool for detecting eating psychopathology in female athletes. Additional longitudinal research is needed to evaluate the predictive value of the CET-A. Copyright © 2017 John Wiley & Sons, Ltd and Eating Disorders Association.

Abstract
BACKGROUND Compulsive exercise (CE) has been the neglected "Cinderella" among eating disorder (ED) symptoms, even though it seems to impact severity, treatment and outcome. This prompted a large-scale and systematic examination of the impact of CE in a representative ED sample. METHODS CE was examined in over 9000 female and male patients from a clinical ED database (covering out-patient, day and/or residential treatment) with respect to prevalence, ED diagnosis, ED symptoms, clinical features, patient characteristics, and outcome at 1-year follow-up. Relationships between changes in CE behavior and remission were also examined. RESULTS CE was a transdiagnostic symptom, present in nearly half of all patients (48%). It was associated with greater overall ED pathology, particularly dietary restraint, and negative perfectionism. Initial CE did not impact remission rate, but patients continuing or starting CE during treatment had considerably lower remission rates compared to patients who never engaged in, or ceased with, CE. Results were comparable for females and males. CONCLUSIONS At baseline, there were few differences between patients with and without CE, except a somewhat higher symptom load for patients with CE, and CE did not predict ED outcome. However, how CE developed during treatment to 1-year follow-up considerably impacted remission rates. We strongly recommend CE to be systematically assessed, addressed, and continuously evaluated in all ED patients seeking treatment.

Abstract
Objective The present study aimed to investigate disordered eating (DE) among Sami compared with non-Sami residing in northern Norway. Design In a cross-sectional design, stratified by sex and ethnicity, associations were tested between DE (Eating Disturbance Scale; EDS-5) and age, education level, BMI category, anxiety and depression, physical activity and consumption of snacks. Setting The SAMINOR 2 Clinical Survey (2012–2014) based on the population of ten municipalities in northern Norway. Subjects Adults aged 40–69 years; 1811 Sami (844 male, 967 female) compared with 2578 non-Sami (1180 male, 1398 female) individuals. Results No overall significant ethnic difference in DE was identified, although comfort eating was reported more often by Sami individuals (P=0·01). Regardless of ethnicity and sex, symptoms of anxiety and depression were associated with DE (P<0·001). Furthermore, DE was more common at lower age and higher BMI values. Education levels were protectively associated with DE among Sami men (P=0·01). DE was associated (OR, 95% CI) with low physical activity in men in general and in non-Sami women (Sami men: 2·4, 1·4, 4·0; non-Sami men: 2·2, 1·4, 3·6; non-Sami women: 1·8, 1·2, 2·9) and so was the consumption of snacks (Sami men: 2·6, 1·3, 5·0; non-Sami men: 1·9, 1·1, 3·1; non-Sami women: 2·1, 1·3, 3·4). Conclusions There were no significant differences regarding overall DE comparing Sami with non-Sami, although Sami more often reported comfort eating. There were significant sex and ethnic differences related to DE and physical activity, snacking and education level.
