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.
The objective of this study was to evaluate the psychometric properties of the Life Satisfaction Scale in the Brazilian sport context.
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.
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.
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.
