RESUMEN
BACKGROUND: There is a strong association between perfectionism and eating disorders. In a cognitive-behavioural model of compulsive exercise it has been suggested there are reciprocal associations between perfectionism, eating disorder pathology, and compulsive exercise. No study has examined if there is an indirect association between perfectionism and compulsive exercise through eating disorder pathology, which would inform a preliminary understanding of the cognitive-behavioural model of compulsive exercise. METHODS: The sample included 301 adolescent females diagnosed with eating disorders (age M = 14.89, SD = 0.85, range 13-17). We tested models of direct and indirect associations of compulsive exercise in the relationship between perfectionism and eating disorder pathology, and direct and indirect associations of eating disorder pathology in the relationship between compulsive exercise and perfectionism. RESULTS: Perfectionism was directly associated with eating disorder pathology and compulsive exercise. Perfectionism was indirectly associated with eating disorder pathology through compulsive exercise. Perfectionism also had an indirect association with compulsive exercise through eating disorder pathology. DISCUSSION: The findings suggest it would be useful for future prospective research to examine the cognitive-behavioural model of compulsive exercise in adolescents with eating disorders. Compulsive exercise and perfectionism may be useful targets for future research to improve eating disorder treatment. Level of evidence Level V: Opinions of respected authorities, based on descriptive studies, narrative reviews, clinical experience, or reports of expert committees.

OBJECTIVE: The development of novel treatments for anorexia nervosa (AN) requires a detailed understanding of the biological underpinnings of specific, commonly occurring symptoms, including compulsive exercise. There is considerable bio-behavioral overlap between AN and obsessive-compulsive disorder (OCD), therefore it is plausible that similar mechanisms underlie compulsive behavior in both populations. While the association between these conditions is widely acknowledged, defining the shared mechanisms for compulsive behavior in AN and OCD requires a novel approach. METHODS: We present an argument that a better understanding of the neurobiological mechanisms that underpin compulsive exercise in AN can be achieved in two critical ways. First, by applying a framework of the neuronal control of OCD to exercise behavior in AN, and second, by taking better advantage of the activity-based anorexia (ABA) rodent model to directly test this framework in the context of feeding pathology. RESULTS: A cross-disciplinary approach that spans preclinical, neuroimaging, and clinical research as well as compulsive neurocircuitry and behavior can advance our understanding of when, why, and how compulsive exercise develops in the context of AN and provide targets for novel treatment strategies. DISCUSSION: In this article, we (i) link the expression of compulsive behavior in AN and OCD via a transition between goal-directed and habitual behavior, (ii) present disrupted cortico-striatal circuitry as a key substrate for the development of compulsive behavior in both conditions, and (iii) highlight the utility of the ABA rodent model to better understand the mechanisms of compulsive behavior relevant to AN. PUBLIC SIGNIFICANCE: Individuals with AN who exercise compulsively are at risk of worse health outcomes and have poorer responses to standard treatments. However, when, why, and how compulsive exercise develops in AN remains inadequately understood. Identifying whether the neural circuitry underlying compulsive behavior in OCD also controls hyperactivity in the activity-based anorexia model will aid in the development of novel eating disorder treatment strategies for this high-risk population.

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. LEVEL OF EVIDENCE: Level V, Cross-sectional, Psychometric study.

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.

PURPOSE: This study aimed to examine changes in compulsive exercise among adults with eating disorders (ED) admitted for inpatient treatment in a randomized controlled trial comparing cognitive behavioral therapy (CBT) and compassion-focused therapy (CFT) and whether such changes were influenced by treatment condition, childhood trauma, or level of compulsive exercise. METHOD: A total of 130 adults admitted to inpatient treatment for EDs mean (SD) age 30.9 (9.7) years, mean illness duration 14.2 (8.9) years, were randomized to receive CBT or CFT and analyzed using multilevel modeling. Assessments included Eating Disorders Examination - Interview, Compulsive Exercise Test and Childhood Trauma Questionnaire. RESULTS: Mean total CET score at baseline was 14.7 (4.0) with no difference between the treatment groups. A total of 63 (48.5%) had CET score ≥ 15, indicating clinical levels. There was an overall time effect on reduction in CET total and all CET subscale scores except Lack of enjoyment, and CFT provided greater reduction compared to CBT on the CET subscale Mood improvements. Patients with clinical CET score levels showed greater reduction on CET total and the subscales Avoidance, Weight, and Rigidity across time compared to persons with non-clinical CET score. Childhood trauma did not predict changes in CET total or subscale scores. DISCUSSION: Both CBT and CFT improve overall compulsive exercise. The greater effect of CFT than CBT on exercise as a maladaptive mood regulator calls for further research on how affective oriented psychotherapies can not only reduce compulsive exercise but also promote functional exercise among persons with EDs. PUBLIC SIGNIFICANCE STATEMENT: Understanding and addressing compulsive exercise in adults with eating disorders is crucial. This study comparing cognitive-behavioral therapy and compassion-focused therapy shows both improve compulsive exercise. Importantly, compassion-focused therapy has a greater impact as an emotion-focused regulator. This emphasizes the need for further exploration into how emotion-focused therapies can reduce compulsive exercise and promote healthier, functional physical activity for individuals with eating disorders.

OBJECTIVE: There remains a lack of consensus around nosology for compulsive exercise (CE). Although widely observed in eating disorders (ED), CE shares theoretical overlap with obsessive-compulsive disorder (OCD), where exercise compulsions occur in response to obsessions. Yet, there is limited and mixed evidence of a relationship between CE with OCD. This study aims to explore the appropriate diagnostic classification of CE through examination of CE in relation to OCD, obsessional thinking, and ED symptoms. METHOD: Two hundred and eighty one adults with mental health symptoms, dieting, and exercise behaviour completed measures of OCD, CE, and disordered eating symptoms. Regression and Receiver Operating Characteristic analyses examined relationships between dimensions of CE with OCD and ED symptoms, and the predictive ability of CE assessment for detecting threshold OCD and ED symptoms. RESULTS: CE assessment was poor at predicting threshold OCD symptoms, probable Anorexia Nervosa, and Binge Eating Disorder and moderate at detecting probable disordered eating and Bulimia Nervosa. Associations between CE and OCD symptoms were not significant after adjustment for ED symptoms. Obsessional thinking was associated only with lack of exercise enjoyment. CONCLUSIONS: Results indicate that excessive exercise might represent a distinct disorder, with some shared traits across CE, OCD and ED symptoms. Findings question the utility of adaptation of OCD diagnostic criteria for CE. Assessment and treatment implications are considered.

BACKGROUND: The similarities and differences between orthorexia nervosa symptoms (ONs) and the symptoms and correlates of eating disorders listed in the DSM-5 need to be elucidated. ONs were examined in a volunteer community sample in conjunction with compulsive exercise, disordered eating, as well as emotional and behavioral correlates of eating disorders. METHODS: Participants were 561 adult volunteers (93 men, 17.09%) aged 19-72 (M = 32.7 ± 11), recruited via social media networks. Participants self-reported on the following measures online: Düsseldorf Orthorexia Scale, Compulsive Exercise Test, Retrospective Child Feeding Questionnaire, Experiences in Close Relationships, Difficulties in Emotional Regulation Scale, Toronto Alexithymia Scale, and Eating Disorder Examination Questionnaire 13. Data were downloaded and analyzed in SPSS26 and Amos26. RESULTS: A theoretical model of the connections between the study variables was tested via SEM and confirmed. The profiles of participants with high, average and low levels of ONs were compared. Participants with the highest levels also scored highest for compulsive exercise, insecure attachment, alexithymia, emotion regulation difficulties, weight and shape concerns, body dissatisfaction, restriction, bingeing, purging and parental feeding practices of concern about child's weight and restricting and monitoring the child's intake of calorie-rich foods. DISCUSSION: High levels of ONs are related to disordered eating attitudes and behaviors, as well as to emotional and behavioral correlates of eating disorders. It is unclear to what extent these ONs are distinguishable from symptoms of other eating disorders listed in the DSM-5. Longitudinal studies may help to elucidate distinct trajectories and risk factors for ON. LEVEL OF EVIDENCE: Level III, case-control analytic study.

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 (Nâ¯=â¯1157; Mage 36.4, standard deviationâ¯=â¯12.9, 77â¯% 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.

OBJECTIVE: Little is known about psychosocial variables that may be differentially associated with compulsive exercise versus adaptive exercise. The current study simultaneously examined associations of exercise identity, anxiety, and body dissatisfaction with both compulsive and adaptive exercise behaviors and investigated which construct may account for the most unique variance in compulsive and adaptive exercise. Hypotheses were that: 1) body dissatisfaction, anxiety, and exercise identity would be significantly associated with compulsive exercise and 2) exercise identity would be significantly associated with adaptive exercise. METHOD: A total of 446 individuals (50.2 % female) completed reports of compulsive exercise, adaptive exercise, body dissatisfaction, exercise identity, and anxiety via an online survey. Multiple linear regression and dominance analyses were used to test hypotheses. RESULTS: Exercise identity, body dissatisfaction, and anxiety were all significantly associated with compulsive exercise. Only exercise identity and anxiety were significantly associated with adaptive exercise. Dominance analyses suggested that exercise identity accounted for the largest proportion of variance in compulsive (Dominance R2 = 0.27) and adaptive exercise (Dominance R2 = 0.45). CONCLUSION: Exercise identity emerged as the strongest predictor of both compulsive and adaptive exercise. The simultaneous presence of exercise identity, body dissatisfaction, and anxiety may contribute to high risk for engagement in compulsive exercise. Incorporating exercise identity into established eating disorder preventions and treatments may contribute to the reduction of compulsive exercise behaviors.

Compulsive exercise (CE) is a core symptom of eating disorders (EDs) that is common in undergraduate men and women. Importantly, CE is a multidimensional construct, and certain facets of CE (i.e., exercise to control weight or to avoid negative affect associated with missed exercise) are more strongly associated with ED symptoms in undergraduate women than others. However, less is known about how CE facets relate to ED symptoms in men. This study examined: 1) gender differences in levels of CE facets, assessed using the Compulsive Exercise Test (CET); 2) whether specific CE facets independently relate to ED symptoms; and 3) whether gender moderates these relationships. Five hundred and ninety-one university students (58.5 % men) completed the CET and Eating Pathology Symptoms Inventory. Women reported significantly greater weight control exercise, exercise for mood improvement, lack of exercise enjoyment, body dissatisfaction, and purging than men, while men reported more muscle building than women. CE motivated by avoidance of negative emotions and performed in a rule-driven manner and weight control CE were associated with the greatest number of ED symptoms. Further, rigid exercise routines were associated with greater muscle building. Women with greater weight control CE experienced more body dissatisfaction, and women with more CE motivated by avoidance of negative emotions experienced more restriction, compared to men. Overall, specific CE facets relate to ED symptoms in men and women. Findings highlight the importance of interventions designed to target unhealthy exercise motivations and of cultivating healthy attitudes towards exercise across genders.

Anorexia nervosa is the most deadly mental disorder. Early detection is crucial. Most patients engage in compulsive exercise, often in an early stage. Compulsive exercise has a deleterious impact on the course of the disease. It can manifest in extreme forms with rigid rules and an inevitable urge. Three different subtypes exist: intensive sports, increased movement in everyday life, and motor restlessness. Besides the underlining motives, neurobiological mechanisms play a role. Moreover, cold ambient temperature increases compulsive exercise, while many patients intentionally expose themselves to cold. Compulsive exercise disappears only partly after weight recovery. Therefore, it needs specific treatment. Psycho-education is indispensable: to learn the difference between healthy and compulsive exercise. Besides decreasing excessive exercising, supervised exercise training is helpful. In short, think of AN in case of compulsive exercise and think of compulsive exercise of case of AN. Pose the right questions to get an impression of the severity.

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.

PURPOSE: Limited research has examined recovery processes and conceptualisations of recovery within orthorexia nervosa (ON). This study harnessed Instagram data to examine how people who self-identify with ON use the hashtag #OrthorexiaRecovery and how recovery is represented within this online space. METHODS: 500 textual posts containing #OrthorexiaRecovery were extracted from Instagram. Co-occurring hashtags were analysed descriptively to determine whether this online space is specific to ON, and textual data were analysed using reflexive thematic analysis. RESULTS: The hashtag analysis indicated that #OrthorexiaRecovery is being used within a wider context of eating disorder recovery and awareness, but also provides deep insights into experiences of recovery from ON. The thematic analysis generated five themes: the invisibility of orthorexia; a turbulent and continuous process; finding food freedom; from compulsive exercise to intuitive movement; a community of support. Our findings suggest that people with self-reported ON experience recovery as a continuous process and the current invisibility of ON within diagnostic criteria and wider society impedes recovery. While working towards recovery, users aimed to be free from diet culture, become more attuned to their bodies, and develop more adaptive relationships with food and fitness. Users noted a general lack of support for people with ON and so used this online space to create a supportive community, though some content was potentially triggering. CONCLUSION: Our findings highlight the importance of increased recognition of ON and the potential value of targeting societal norms and harnessing social identity resources within therapeutic interventions for ON.

Perfectionism has a strong association with eating disorders. Research in non-clinical adults has suggested that perfectionism has both direct and indirect effects on eating disorder symptoms, and that compulsive exercise is a potential mediator. The aim of this study was to understand whether perfectionism is associated with eating disorder symptoms, both directly and indirectly through compulsive exercise in underweight adolescents with eating disorders. Participants were 149 female adolescents (M = 14.90 years, age range 13-17) with eating disorders from the Helping to Outline Paediatric Eating Disorders (HOPE) Project, an ongoing, registry study of individuals consecutively referred individuals to a statewide eating disorder service. The majority had a diagnosis of anorexia nervosa restricting type (66 %), followed by unspecified feeding or eating disorder (21 %), and anorexia nervosa binge-eating purging type (13 %). To test the model, path analyses with bootstrapping were conducted. All paths were statistically significant, including the indirect effect from perfectionism to eating disorder pathology via the mediator of compulsive exercise, and the direct effect of perfectionism on eating disorder pathology. Overall, this research provides further evidence that compulsive exercise may be one factor that can explain the relationship between perfectionism and eating disorder symptoms. Future research should seek to determine the relative efficacy of approaches for the treatment of eating disorders in adolescents which target perfectionism and compulsive exercise.

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.

Today, many women are driven to subscribe to a more athletically oriented appearance ideal hallmarked by muscle tone (referred to as athletic- or fit-looking). However, the constellation of unhealthy eating and exercise behaviors that may accompany the pursuit of toned muscularity among women is not yet well characterized. To address this knowledge gap, our study evaluated the associations among the female drive for toned muscularity and both thinness-oriented disordered eating behaviors (e.g., dietary restriction) and muscularity-oriented disordered eating behaviors (e.g., excessive scrutiny of macro-nutrient values of food), as well as dimensions of compulsive exercise. Participants were 388 Australian undergraduate women who completed an online questionnaire including self-report measures of said constructs. Hierarchical regression models were used to determine whether the drive for toned muscularity accounted for unique variance in eating and exercise behaviors after adjusting for theoretically relevant covariates. Results indicated independent relationships between the drive for toned muscularity and several facets of thinness- and muscularity-oriented disordered eating, as well as compulsive exercise (e.g., exercise rigidity). Our findings further contribute to an emerging literature illustrating that women driven to attain a toned appearance may be vulnerable to engaging in a wide range of maladaptive eating and exercise practices.

PURPOSE: Mental health problems among university students have been reported to be significantly increasing and suggested to be associated with college drop-out. Body dissatisfaction and compulsive exercise are both constructs relevant for mental health problems in general and eating disorders in particular. This study examined associations between body dissatisfaction, compulsive exercise and self-reported symptoms of depression among Swedish university students. METHODS: Participants (n = 4262) are students in an ongoing cohort study, and data from the baseline assessment were used. Four linear regression models were built to explore the associations between body dissatisfaction, compulsive weight control exercise and depressive symptoms. RESULTS: Our findings showed that females reported higher levels of body dissatisfaction than males. Body dissatisfaction and compulsive exercise were associated with self-reported symptoms of depression in this non-clinical population. Results showed that compulsive exercise was negatively associated with reported symptoms of depression, while body dissatisfaction was positively associated with symptoms of depression. CONCLUSION: In line with previous research, there was a gender difference in body dissatisfaction where females displayed higher levels of dissatisfaction than males. Body dissatisfaction was positively associated with reported symptoms of depression, suggesting support of previous research indicating body dissatisfaction to increase mental health problems. Compulsive exercise was negatively associated with symptoms of depression suggesting a behavior negatively reinforced, supporting both constructs to be of interest for reported symptoms of depression in a non-clinical population of Swedish university students. LEVEL OF EVIDENCE: III, cohort study. TRIAL REGISTRATION: http://clinicaltrials.gov/ID : NCT04465435.

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.

PURPOSE: In this study, we aimed to test the relationship between compulsive exercise and self-esteem, body image, and body satisfaction as potential predictors of eating disorders. METHODS: Self-report measures of compulsive exercise beliefs and behaviors, self-esteem, body image, and body satisfaction, were completed by 120 female participants through an online questionnaire. Factor analyses with varimax rotation were performed to create exercise-frequency groups. ANOVA's were performed on Body Mass Index (weight adjusted for height squared, BMI), current minus ideal weight, self-esteem, body image, and body satisfaction to determine if there were differences depending on these exercise groups. RESULTS: Factor analysis revealed two factors for compulsive exercise beliefs and behaviors: (1) Exercise Fixation, and (2) Exercise Frequency and Commitment. Based on those factors, participants were subdivided into four clusters: (1) pathological obligatory exercisers, (2) exercise fixators, (3) committed exercisers, and (4) non-exercisers. No differences were found between these groups for BMI or current minus ideal weight. Pathological obligatory exercisers and committed exercisers spend significantly more hours on exercise weekly compared to exercise fixators or non-exercisers. No differences between pathological obligatory exercisers, exercise fixators, and non-exercisers were found on self-esteem or body satisfaction, where the committed exercisers scored significantly better. Both committed exercisers and non-exercisers scored significantly better on body image flexibility compared to pathological obligatory exercisers and exercise fixators. CONCLUSION: Compulsive exercise has both an exercise volume and an emotional component. The level of compulsive exercise is linked to one's self-esteem, body image, and body satisfaction and those factors could be a target for future interventions.
