Propriedades psicométricas da escala de satisfação com a vida no contexto esportivo Brasileiro

Abstract

Introduction: The subjective well-being is a construct referring to the perception that people have of their life and the evaluation that they make of it. Objective: The objective of this study was to evaluate the psychometric properties of the Life Satisfaction Scale in the Brazilian sport context. Methods: A total of 593 athletes (371 men) participated in the study, of which 180 (30.4%) practiced individual modalities and 413 (69.4%) collective modalities. By means of exploratory and confirmatory factor analysis, it was possible to verify that the items loaded in only one domain, with adequate adjustment indexes (comparative fit index [CFI] = 0.99; Tucker-Lewis Index [TLI] = 0.98; standardized root mean square residual [SRMR] = 0.016; standardized root mean square error of approximation [RMSEA] = 0.026), confirming the unidimensionality assumption of the construct. Results: The results showed good internal consistency (α=0.804) and a statistically significant correlation between all items (p<0.05). The covariance analysis showed that life satisfaction was influenced by age (F [4.568] p<0.033), that is, the instrument score varied according to the respondent’s age. Conclusion: It was concluded that the Life Satisfaction Scale presents excellent psychometric properties for use in athletes, constituting a viable option for the measurement of satisfaction with life in the sport context. Level of Evidence I; Testing of previously developed diagnostic criteria on consecutive patients (with universally applied reference “gold” standard).
