Exercise Dependence Scale (EDS-21): Translation and Psychometric Validity for Use in Brazilian Dancers

ABSTRACT Exercise addiction is a dysfunctional behavior that includes excess and loss of control over physical activity or training, accompanied by negative consequences. The aim of the present study was to cross-culturally adapt the “Exercise Dependence Scale” for Brazilian dancers. Six judges evaluated the items and 338 dancers (Age=15.52 years; ±3.55) responded to the instrument. A prevalence of 54% were identified as symptomatic and 8.7%, as exercise dependent. Principal component and network analysis indicated seven symptom clusters. The instrument demonstrated internal consistency (α=0.84). The norms were developed using Item Response Theory. The “Exercise Dependence Scale” demonstrated validity evidence of its internal structure, making it suitable for evaluating adolescent dancers.
