VVIQ2
Marks (1995) published a new version of the VVIQ, the VVIQ2. This questionnaire consists of twice the number of items and reverses the rating scale so that higher scores reflect higher vividness. Campos and Pérez-Fabello (2009) evaluated the reliability and construct validity of the VVIQ and the VVIQ2. Cronbach a reliabilities for both the VVIQ and the VVIQ-2 were found to be high. Estimates of internal consistency reliability and construct validity were found to be similar for the two versions.
