Propriedades psicométricas da versão brasileira do Exame Geronto Psicomotor

The present study verified the evidence of validity and reliability of the Brazilian Geronto Psychomotor Exam (EGP-Br). 215 participants, mean age 70.22 years (SD: + 6.59) answered a sociodemographic questionnaire and were evaluated using the EGP-Br. The data were analyzed using Exploratory Factor Analysis, Cronbach's alpha, considering the adjustment indices: GFI (Goodness of Fit Index), AGFI (Adjusted Goodness of Fit Index) and RMSR (Root Mean Square Residual) and the Average Variance extracted. Factor Analysis indicated a structure with three factors: Factor 1 = Cognition (α = 0.90); Factor 2 = Joint Mobility (α = 0.80); Factor 3 = Equilibrium (α = 0.70), with good adjustment rates (GFI = 0.99; AGIF = 0.99; RMSR = 0.03). The psychometric parameters presented by factors 1, 2 and 3 were respectively: Convergent Validity = 0.55; 0.70; 0.50. Discriminant Validity = 0.74; 0.84; 0.70. In conclusion, the EGP-Br presents good evidence of validity and reliability, suitable for use in the Brazilian context.
