Constru？？o e evidências psicométricas de uma escala de avalia？？o da percep？？o visual

the main objective of this study was to develop and examine the psychometric parameters of an instrument used to evaluate adults' visual perception. the basic assumption was that visual perception includes constancy of form, figure-ground, position and spatial relation. a 4-factor solution was expected. respondents were 183 healthy adults without cognitive or visual perception impairment. in the instrument it was possible to establish the existence of inter-judges agreement, semantic adequacy and test-retest significance. the reliability coefficients ranged from 0.84 to 0.93. the four expected factors were found, each one containing 5 items. this solution accounted for 57.52% of the construct variance indicating that the instrument has good psychometric parameters, which suggests its applicability in scientific research and clinical practice.
