This paper analyses the five-factor structure of the AF5 Self-Concept Questionnaire in dance practitioners and non-practitioners. The responses of 1630 adults (490 dancers and 1.240 non dance practitioners) were analysed using structural equation modelling. The oblique factorial structure, proposed by the author's scale, resulted in a better fit than two alternative structures (one-factor and orthogonal configurations), and was invariant across the two groups. Nevertheless, the factorial means and correlations of the physical with the professional and family dimensions were higher in the dancer group. Reliability was good for both the dancer and non-practitioners group
