Resumen

Likert-type items are commonly used in social science research. This study explores if changing the response format of a scale could improve its psychometric properties. The compared response formats were the five-point Likert scale and the VAS (Visual Analog Scale). 584 participants (75.2 % women) with a mean age of 32.9 ages (SD = 13.4) answered an online survey VAS with two personality questionnaires that were applied twice, one with Likert items (0-4) and another with VAS items (0-100). Discrimination indexes, reliability, and factor loadings from scales with the Likert response format were higher than the ones found in the VAS scales. The response format did not affect the factorial structure of the scales. The VAS response format scales gave higher scores than the Likert response format scales. Although Likert response format showed better properties, this result may have been influenced by the line length of the VAS scale.
