Is Problematic Physical Activity (PPA) a Uni- or Multi-Dimensional Concept? A Bifactor Analysis of the Exercise Dependence Scale-Revised (EDS-R).

The study of exercise dependence, or as we prefer, problematic physical activity (PPA), faces both theoretical and methodological challenges. Different factorial solutions were obtained for the widely used Exercise Dependence Scale-Revised (EDS-R), leading us to question both its latent underlying construct and the interpretation of its factor solutions. Through confirmatory factor analysis (CFA) and the use of a bifactor model (BCFA), we assessed the dimensionality of a French version of the EDS-R. We recruited 745 students from Paris Nanterre University, but we removed 88 responses (16.8%) to retain only those who (a) engaged in a moderate to high levels of physical activity, according to the Global Physical Activity Questionnaire (GPAQ; N = 494; 9.5%), and (b) completed the EDS-R. We used a final sample of 435 students (58.4% of the total population) for a factorial analysis of the EDS-R. We conducted a three-step CFA in Mplus, producing three models: (a) unidimensional, (b) second-order, and (c) bi-factor (BCFA). The results of the BCFA indicated that most EDS-R items were better indicators of a general factor than their respective group factors, except for the second factor measuring a withdrawal construct. These results add to an ongoing debate in the field of behavioral addiction as to how to better conceptualize and measure exercise dependence or PPA. Withdrawal appears to have a special position in this debate, since our BCFA suggested that it is the only specific sub-dimension of the EDS-R scale.

Chinese version of exercise dependence scale-revised: psychometric analysis and exploration of risk factors.

Exercise addiction (EA) is a dysfunctional behavior characterized by exaggerated training which has adverse effects on physiology and psychology. To examine the reliability and validity of the Chinese version of the Exercise Dependence Scale-Revised (EDS-R) and the social and psychological aspects related to EA, a large sample behavioral study was conducted. College students were selected as the target group. All of them were asked to finish the scales about exercise, including the Chinese version of EDS-R and the Motives for Physical Activity Measure-Revised scales. A confirmatory factor analysis, Mann-Whitney U test, and hierarchical regression test were performed to test the reliability and validity of the Chinese version of EDS-R and find the explanatory variables of EA. A total of 837 (556 female) students with a mean age of 20.38 years were recruited in the present study. The Chinese version of EDS-R showed good reliability and validity (McDonald's ω = 0.973, CR = 0.99, AVE = 0.80) in Chinese college students. EA was positively correlated with exercise frequency and ability motivation across the study sample. Besides, the Mann-Whitney U test revealed that the exercise motivation difference is the primary cause of the gender gap in EA. The Chinese version of EDS-R is a relatively robust and accurate instrument to assess the risk of EA. Additionally, exercise frequency and motivation may be the potential risk factors for EA. The screening of risk factors is of great significance for the early detection and prevention of EA.

Physical Exercise Addiction Among Students Based on the EDS-R Scale Adapted for Poland

The purpose of the research was to adapt the Exercise Dependence Scale – Revised (EDS-R) by H. A. Hausenblas and D. Symons Downs to the Polish context and to evaluate the exercise addiction rate among students. The research was conducted online with 290 interviewees aged 19–23 years. Factor analysis confirmed the 7-factor structure of the EDS-R test and its good internal consistency. All the subscales were characterized by adequate reliability. To evaluate scale’s accuracy, the correlation between the EDS-R scale and a question concerning the number of hours of exercise per week was measured. The number of hours spent exercising per week was favorably connected with all of the subscales of the EDS-R. Those results were confirmed by differential analysis. Based on the EDS-R test, the participants were classified as (1) at risk of exercise addiction (5.5%), (2) not addicted (symptomatic group) (72.8%) and (3) not addicted (asymptomatic) (21.7%). The material presented in the article may contribute to further research using the Polish adaptation of the EDS-R scale in different populations (e.g., due to different physical activities undertaken by the exercisers).

Factorial Validity and Psychometric Properties of Exercise Dependence Scale Revised Among Lebanese Exercisers.

The aim of this manuscript is to discuss the reliability and the factorial, convergent and discriminant validities in measurement model of the 21-item Exercise Dependence Scale Revised (EDS-R) used for diagnosing exercise addiction. A study was conducted among 695 (364 male and 331 female) Lebanese bilingual young adults (aged 18–25) who filled the English version of this questionnaire, along with a general questionnaire. This study showed that, despite an acceptable fit index confirming the 7-factor structure and invariance across gender, exercise duration and age groups; the EDS-R lacks in reliability and convergent and discriminant validities in measurement model, due particularly to the “Reduction in other activities” subscale. The construction of the EDS-R is then to be discussed.

Risk of Dependence on Sport in Relation to Body Dissatisfaction and Motivation

The aim of this study was to investigate the risk of dependency on physical exercise in individual sportspeople and the relationship with body dissatisfaction and motivation. Two hundred and twenty-five triathletes, swimmers, cyclists, and athletics competitors aged 18 to 63 years old took part in the study, of which 145 were men (M = 35.57 ± 10.46 years) and 80 were women (M = 32.83 ± 10.31 years). The EDS-R (Exercise Dependence Scale-Revised) was used to study dependency on exercising, the Body Shape Questionnaire (BSQ) was used to study body dissatisfaction, the Behaviour Regulation in Exercise Questionnaire (BREQ-3) was used to determine the participants’ motivation and the BIAQ was used to analyse conducts of avoidance to body image. The obtained results show that 8.5% of the subjects have a risk of dependency on exercise and 18.2% tend to have corporal dissatisfaction, without meaningful differences in the kind of sport they practiced. However, there were important differences concerning the dependency on physical exercise (15% vs. 4.8%) and body dissatisfaction (31.1% vs. 11%) in relation to sex, with the higher percentages referring to women. Introjected regulation and the conduct of food restriction were predictor variables of the dependency on exercise and corporal dissatisfaction. Also, the number and duration of sessions; the age of the participants; the integrated, introjected, and external regulations surrounding social activities; and eating restraints could all predict dependence on physical exercise (DPE).

Examining the relationship between fitness-related self-conscious emotions, disordered eating symptoms, and morbid exercise behavior: An exploratory study

Background and aimsTheoretical models of morbid exercise behavior (MEB) suggest that it may emerge as a result of complex interactions between a range of psychosocial factors. However, in spite of fitness-related self-conscious emotions involving such factors, their relationship with the risk of MEB has never been investigated. Consequently, this study had two objectives. First, to explore the relationship that fitness-related self-conscious emotions have with (a) symptoms reflecting MEB as assessed by the Exercise Addiction Inventory (EAI) and the Exercise Dependence Scale-Revised (EDS-R) and (b) exercise frequency. Second, to examine whether these relationships might vary according to disordered eating symptoms.MethodsA sample of 646 undergraduate students (59% males; Mage = 21.25; SDage = 2.94) completed a self-reported questionnaire.ResultsAfter controlling for age, sex, and disordered eating symptoms, it was found that shame, hubristic pride, and authentic pride positively explained MEB; for their part, guilt (negatively) and authentic pride (positively) explained exercise frequency. The positive relationships between pride and MEB were weaker (in the case of the hubristic facet) or stronger (in the case of the authentic facet) under higher levels of disordered eating symptoms. The independent variables explained 29% (EAI), 28% (EDS-R), and 27% (exercise frequency) of the variance in dependent variables.DiscussionTempering fitness-related emotions of shame, guilt, hubristic pride, and authentic pride may contribute to healthier exercise behavior.

Relationship among sociodemographic and sport variables, exercise dependence, and burnout: a preliminary study in athletes

<p align="left">The aim of the study was to determine the prevalence of exercise dependence and athlete burnout and their relationship between them and among demographic and sport characteristics in 449 athletes, 320 males and 129 females (Age: <em>M</em>= 19.71, <em>SD</em>= 6.62). All of them replied the Spanish versions of Exercise Dependence Scale-Revised (EDS-R) and reduced version of Athlete Burnout Questionnaire (ABQ). The results showed a risk of exercise dependence in 8.7% of the athletes, with statistically significant differences in age (a greater exercise dependence was found in athletes under the age of 18 years old), not in gender, sport dedication and type of sport. Regarding burnout, measured through its three dimensions, the data showed 4% for emotional/physical exhaustion (EFE) and 4.9% for sport devaluation (SD) and reduced sense of accomplishment (RSA). Men and team-sport athletes showed a greater RSA. Men and athletes over the age of 18 also showed more DS. As for sport dedication, participants who spent less time training had higher levels of RSA, whereas those who dedicated more time, had higher levels of EFE. Finally, the relationship between exercise dependence and burnout showed that all dimensions of burnout correlated positively with exercise dependence. </p>

Evaluating the Psychometric Properties of the Exercise Dependence Scale-Revised (EDS-R) in a Spanish Sample

Introduction: There are several instruments to evaluate behavioural addictions. Furthermore, several specific scales have been developed to assess various aspects of exercise dependence. Nevertheless, in Spain there is a lack of specific instruments designed to assess exercise dependence.Objective: This study aims to examine the psychometric properties of a Spanish version of the Exercise Dependence Scale-Revised.Method: 175 university students who were regular exercisers (M=59.11, SD=15.89) took part in the study. They were requested to complete the EDS-R, as well as the General Addiction Scale. The requirement to take part in the study was to exercise a minimum of four times per week.Results: Findings provide initial support for the psychometric properties of the scale as its internal consistency (Cronbach’s alpha: 0.907), and construct and convergent validity with the EAG-RC (r=.559; p<.001) are adequate. In addition, its structure did not need to be modified, as it kept the 21 original items from the American version. Factor analysis yielded a five-factor structure (tolerance, loss of control, continuity, intensity, and withdrawal symptoms) which differ from the ones obtained in the original (American) and French versions where seven factors were obtained. This correlated five-factor model explains 50% of the variance.Conclusion: This Spanish EDS-R, which presents adequate psychometric properties, will provide researchers and clinicians with specific data on this screening tool for assessing exercise dependence. Further research is needed to confirm the current results and check its validity both in research and clinical practice.

Exercise Dependence, Affect, And Preferred Weight Of Female Exercisers

Regular exercise offers many benefits, but some individuals may develop a dependency on exercise to continue receiving these benefits, such as affect regulation or attaining a preferred weight. PURPOSE: To examine associations among exercise dependence, affect, and current and preferred weight of female exercisers who hire personal trainers. METHODS: Female exercisers (n=39; 47+13 yrs; 167+36 lbs) who hire personal trainers at fitness centers in the Midwest completed the Exercise Dependence Scale-Revised (EDS-R), Positive Affect and Negative Affect Scale, and Eating Attitudes Test (EAT-26). A separate questionnaire collected demographic and exercise information as well as perceptions about their personal trainer. A difference score between their current and preferred weight (C-PW) was also created. Pearson correlations were used to identify predictor variables that were related (p < .10) to the exercise dependence score, and these predictor variables were included in a backward multiple regression with the exercise dependence score as the criterion variable. RESULTS: The exercise dependence score was related to positive affect (r = .33 p < .05) negative affect (NA: r = .29, p = .07), C-PW (r = -.45 p < .01), current weight (r = -.31, p = .05), minutes per week exercising without their personal trainer (ExwoT: r = .37, p < .05), and the extent they followed their personal trainer’s suggestions for exercise (r = .36, p < .05). Regression results indicated a final model of three predictors (NA, C-PW, ExwoT) for the exercise dependence score, R2 = .45, R2adj = .41, F(3,35) = 9.36, p < .001. The unstandardized and standardized coefficients are provided in parentheses for NA (1.169, .335, p < .001), C-PW (-.195, -.343, p < .05), and ExwoT (.046, .431, p < .01). CONCLUSION: Female exercisers with more negative affect who were closer to their preferred weight and exercised more without their personal trainer were found to have higher exercise dependence scores. Thus, female exercisers may be using exercise as a means to self-regulate negative affect, and as they get closer to their preferred weight, they exercise more than what they do with their trainer. Personal trainers and exercisers should be aware because as women become more tolerant of exercise, this behavior may lead to clinically significant issues.

Exercise Dependence Scale: adaptação e evidências de validade e precisão

RESUMO Objetivo O presente estudo teve como objetivo conhecer evidências de validade e precisão da Exercise Dependence Scale-Revised (EDS-R). Métodos Contou-se com uma amostra não probabilística de 709 praticantes de exercício físico de todo o Brasil, com idades variando entre 12 e 73 anos (M = 25,7; DP = 8,43), a maioria do sexo masculino (55,1%) e apresentando o estado civil solteiro (75,5%). Os participantes responderam a EDS-R e questões demográficas. Procurando conhecer a estrutura fatorial, foram utilizados procedimentos de análise fatorial exploratória e confirmatória. Adicionalmente, a fim de avaliar a precisão do instrumento, efetuaram-se cálculos de alfa de Cronbach (consistência interna) e correlações de r de Pearson. Resultados A partir das análises exploratórias (principal axis factoring), foi observada uma variância explicada de 62,7% para uma estrutura de sete fatores. A consistência interna total da escala foi de 0,88, com índices de alfa de Cronbach variando de 0,68 a 0,89 entre os fatores. Os coeficientes de correlação variaram de 0,10 a 0,65, apontando para uma inter-relação entre as dimensões. Os procedimentos de análise fatorial confirmatória corroboraram a estrutura heptafatorial a partir de indicadores satisfatórios de bondade de ajuste do modelo [χ2 (168) = 288,21; p &lt; 0,001, χ2/gl = 1,78, GFI = 0,93, CFI = 0,95 e RMSEA = 0,04 (IC90% = 0,037-0,055)]. Conclusões Os achados apoiaram a adequação psicométrica da EDS-R, a partir das análises exploratórias e confirmatórias, em consonância com o modelo teórico de dependência de exercício físico.

FACTORIAL VALIDITY OF THE KOREAN VERSION OF THE EXERCISE DEPENDENCE SCALE-REVISED.

This study evaluated the psychometric properties of the Korean version of the 21-item Exercise Dependence Scale-Revised (EDS-R). The EDS-R was designed to measure the multidimensional aspects of exercise dependence symptoms such as withdrawal, continuance, tolerance, lack of control, reductions, time, and intention. Although the EDS-R has demonstrated sound psychometric properties, it has only been validated in Western samples. Cross-cultural validations of the instrument may increase the knowledge of exercise dependence. Therefore, this study aimed to contribute to the file by investigating the validity and utility of the construct of the EDS-R, using a non-Western sample. 402 adult participants who were over 18 years of age and who reported exercising at least once a week were asked to complete the EDS-R. The results from factor analyses supported that the seven-factor model of exercise dependence symptoms showed an adequate fit for both men and women. The EDS-R scores differentiated between samples, with varying amounts of exercise; 15.4% of the sample was classified as being at risk for exercise dependence. In sum, the results indicated that the EDS-R is a psychometrically reliable assessment tool for exercise dependence symptoms in Korea.

Spanish version of Adonis Complex Questionnaire. A questionnaire to test the muscle dimorphism and vigorexy

To validate the Spanish version of Adonis Complex Questionnaire in bodybuilders. Participants included 99 bodybuilders who train regularly (age: 25.45±5.19 y; BMI=24.53±1.89). In order to test the discriminant and concurrent validity the Exercise Dependence Scale-Revised (EDS-R) and the Eating Attitudes Test (EAT-26) were used. The scale's psychometric properties were obtained through a concurrent validity process, factorial analysis of principal components, internal consistency, and test-retest reliability. The internal consistency of this questionnaire was high (Cronbach's Alpha= 0.880) in total scale. The intraclass correlation coefficient (ICC) to test the temporal consistency of the questionnaire was 0.707 (95% IC=0.336- 0.871). The questionnaire obtained concurrent validity with the EDS-R (r=0.613, p<0.001), and EAT-26 (r=0.422, p<0.001). The results have shown a three-factor structure Factor 1: psychosocial effect of physical appearance, Factor 2: control of physical appearance, Factor 3: concern about physical appearance which explain 65.29% of variance. The Adonis Complex Questionnaire shows a proper psychometric properties and it is a valid and reliable measure of vigorexy and muscle dimorphism in bodybuilders.

Personality traits and exercise dependence: Exploring the role of narcissism and perfectionism

There are currently limited investigations that have examined the relationship between personality traits and exercise dependence. The purpose of the present study was to explore the relationship between exercise dependence, narcissism and perfectionism. Ninety regular exercisers were recruited from various gyms, fitness centres and sporting events to complete the Narcissistic Personality Inventory [Raskin, R. N., & Terry, H. (1988). A principal-components analysis of the Narcissistic Personality Inventory and further evidence of its construct validity. Journal of Personality and Social Psychology, 54(5), 890–902], Multidimensional Perfectionism Scale [Hewitt, P. L., & Flett, G. L. (1991). Perfectionism in the self and social contexts: Conceptualization, assessment, and association with psychopathology. Journal of Personality and Social Psychology, 60(3), 456–470] and Exercise Dependence Scale-Revised [Symons Down, D., Hausenblas, H. A., & Nigg, C. R. (2004). Factorial validity and psychometric examination of the Exercise Dependence Scale-Revised. Measurement in Physical Education and Exercise Science, 8(4), 183–201] either online or in person. Exercise dependence was positively related to narcissism, self-orientated perfectionism and socially prescribed perfectionism. Gender differences between these relationships were also found. Hierarchical regression analysis indicated that a combination of narcissism and self-orientated perfectionism uniquely predicted a greater degree of exercise dependence. These findings indicate that both narcissism and perfectionism may be important antecedents of exercise dependence, and that a combination of these personality traits is associated with exercise dependence. Future research should continue to determine which personality traits contribute to the personality profile of individuals with exercise dependence.

Psychometric examination and factorial validity of the Exercise Dependence Scale-Revised in Italian exercisers.

Background and aims The purpose of this study was to verify the factorial structure, internal validity, reliability, and criterion validity of the 21-item Exercise Dependence Scale-Revised (EDS-R) in an Italian sample. Methods Italian voluntary (N = 519) users of gyms who had a history of regular exercise for over a year completed the EDS-R and measures of exercise frequency. Results and conclusions Confirmatory factor analyses demonstrated a good fit to the hypothesized 7-factor model, and adequate internal consistency for the scale was evidenced. Criterion validity was evidenced by significant correlations among all the subscale of the EDS and exercise frequency. Finally, individuals at risk for exercise dependence reported more exercise behavior compared to the nondependent-symptomatic and nondependent-asymptomatic groups. These results suggest that the seven subscales of the Italian version of the EDS are measuring the construct of exercise dependence as defined by the DSM-IV criteria for substance dependence and also confirm previous research using the EDS-R in other languages. More research is needed to examine the psychometric properties of the EDS-R in diverse populations with various research designs.

Dependence and Physical Exercise: Spanish Validation of the Exercise Dependence Scale-Revised (EDS-R)

The purpose of this study was to validate the Spanish version of the Exercise Dependence Scale-Revised (EDS-R). To achieve this goal, a sample of 531 sport center users was used and the psychometric properties of the EDS-R were examined through different analyses. The results supported both the first-order seven-factor model and the higher-order model (seven first-order factors and one second-order factor). The structure of both models was invariant across age. Correlations among the subscales indicated a related factor model, supporting construct validity of the scale. Alpha values over .70 (except for Reduction in Other Activities) and suitable levels of temporal stability were obtained. Users practicing more than three days per week had higher scores in all subscales than the group practicing with a frequency of three days or fewer. The findings of this study provided reliability and validity for the EDS-R in a Spanish context.

Relationships among Exercise Dependence, Commitment, Identity

The purpose of this research was to adopt the commitment and identity perspectives to examine the relationship between exercise dependence and exercise behavior. Two hundred and eighty-two regular exercisers, aged from 18 to 55 years (34.69±9.66) were participated in this study. All the subjects were attended to Leisure Time Exercise Questionnaire (LTEQ), Exercise Commitment Scale (ECS), Exercise Identity Scale (EIS) and Exercise Dependence Scale-Revised (EDS-R). Results of this research showed that exercise dependence correlated with exercise commitment and identity. In addition, Structural Equation Modeling (SEM) analysis found both exercise identity and have-to-commitment directly and indirectly predicted exercise dependence and vigorous exercise behavior. However, want-to-commitment failed to predict dependence and exercise behavior. Moreover, risk-dependence exercisers had higher vigorous exercise behavior than non-dependence symptomatic and non-dependence asymptomatic exercisers. This study concludes that both exercise identity and exercise commitment have direct and indirect influence on exercise dependence and exercise behavior. Additionally, exercise dependence may cause negative effect on exercisers. Therefore, exercise instructors and professionals need to deeply understand the antecedents and related variables of exercise dependence in order to develop a better exercise program and achieve better effects of exercise.

Étude confirmative de l’échelle de dépendance à l’activité physique Exercise Dependence Scale-Revised pour une population francophone

Sur la base des critères diagnostiques de dépendance aux substances du DSM-IV [American Psychiatric Association. Diagnostic and statistical manual of mental disorders. 4th ed. Washington, DC: American Psychiatric Association; 1994.], Hausenblas et Downs [Exercise dependence: a systematic review. Psychol Sport Exerc 2002;3(2):89–123.] développent pour une population anglophone, une échelle d’évaluation des symptômes de dépendance à l’activité physique : l’Exercise Dependence Scale-Revised (EDS-R). Cette échelle est composée de sept facteurs. L’objectif de cette étude est de confirmer la présence de ces facteurs pour une version française de l’EDS-R [Factorial validity and psychometric examination of the exercise dependence scale-revised. Meas Phys Educ Exerc Sci 2004;8(4):183–201.]. La population étudiée est composée de 516 participants, engagés à un semi-marathon (moyenne d’âge égale à 39,02). L’analyse en composante principale réalisée sur la version française de l’EDS-R présente un nombre de facteurs (six facteurs) différent de celui de la version originale (sept facteurs). Cependant, les indices d’ajustement obtenus par une analyse factorielle confirmatoire montre que le modèle original demeure le plus pertinent. Les alphas de Cronbach des sept facteurs sont bons et présentent la version française de l’EDS-R comme une mesure valide de la dépendance à l’activité physique pour une population francophone. Since the first writings on excessive exercise, there has been an increased interest in exercise dependence. One of the major consequences of this increased interest has been the development of several definitions and measures of exercise dependence. The work of Veale [Does primary exercise dependence really exist? In: Annet J, Cripps B, Steinberg H, editors. Exercise addiction: Motivation for participation in sport and exercise.Leicester, UK: Br Psychol Soc; 1995. p. 1–5.] provides an advance for the definition and measure of exercise dependence. These studies have adapted the DSM-IV criteria for substance dependence to measure exercise dependence. The Exercise Dependence Scale-Revised is based on these diagnostic criteria, which are: tolerance; withdrawal effects; intention effect; lack of control; time; reductions in other activities; continuance. Confirmatory factor analyses of EDS-R provided support to present a measurement model (21 items loaded in seven factors) of EDS-R (Comparative Fit Index = 0.97; Root mean Square Error of Approximation = 0.05; Tucker-Lewis Index = 0.96). The aim of this study was to examine the psychometric properties of a French version of the EDS-R [Factorial validity and psychometric examination of the exercise dependence scale-revised. Meas Phys Educ Exerc Sci 2004;8(4):183–201.] to test the stability of the seven-factor model of the original version with a French population. A total of 516 half-marathoners ranged in age from 17 to 74 years old (Mean age = 39.02 years, ET = 10.64), with 402 men (77.9%) and 114 women (22.1%) participated in the study. The principal component analysis results in a six-factor structure, which accounts for 68.60% of the total variance. Because principal component analysis presents a six-factor structure differing from the original seven-factor structure, two models were tested, using confirmatory factor analysis. The first model is the seven-factor model of the original version of the EDS-R and the second is the model produced by the principal component analysis. The results of confirmatory factor analysis presented the original model (with a seven-factor structure) as a good model and fit indices were good (X2/ddl = 2.89, Root Mean Square Error of Approximation (RMSEA) = 0.061, Expected Cross Validation Index (ECVI) = 1.20, Goodness-of-Fit Index (GFI) = 0.92, Comparative Fit Index (CFI) = 0.94, Standardized Root Mean Square (SRMS) = 0.048). These results showed that the French version of EDS-R has an identical factor structure to the original. Therefore, the French version of EDS-R was an acceptable scale to measure exercise dependence and can be used on a French population.
