Abstract:The purpose of this study was to test the preliminary VIPA for its psychometric properties and to explore associations of the questionnaire. The aim of VIPA is to measure differences in patient satisfaction between the use of 2D images and 3D images. 106 trauma patients with bone fractures answered VIPA. PCA indicated a factor structure of two different factors. These factors were interpreted as ‘the importance of seeing images’ and ‘clearness of the image’. Both factors showed an adequate Cronbach’s α with values of 0.84 and 0.75. There were no indicators for severe floor or ceiling effects. The correlation of Spearman’s ρ between the two factors was not sufficient to calculate a total score (r = 0.34), so the factors have to be scored independently. The two factors were both moderately correlated with overall satisfaction of imaging. Based on the outcomes, it is suggested that the final VIPA is a valid and reliable instrument to measure patients’ satisfaction with the use of images that can be used for further research. VIPA can now be used to measure difference in satisfaction among groups of patients about the use of 2D and 3D images.
