[Adaptation to Spanish of the Vividness of Visual Imagery Questionnaire-Revised Version (VVIQRV)]

Adaptation to Spanish of the Vividness of Visual Imagery Questionnaire-Revised Version (VVIQRV). The main goal of this paper was to adapt to Spanish language and to examine the psychometric properties of the "Vividness of Visual Imagery Questionnaire-Revised Version" (VVIQRV), an instrument that can be used to assess vividness of visual imagery. The adaptation was carried out starting from the Spanish version of VVIQ and taking into consideration improvement proposals suggested in other studies. The questionnaire was then administered to a sample of 414 Spanish university students and the psychometric characteristics were estimated on the basis of the classic theory and the Rasch rating scale model (RSM). The results were convergent with previous studies and indicated that the Spanish VVIQRV has good internal consistency and can be characterized by a single main factor structure. Also, the RSM analysis showed that the increment in the number of response categories, a proposal to improve the instrument, was not appropriate.
