Randomized comparative study on feasibility of electronic version of the Pediatric Quality of Life Inventory (ePedsQL) - Development of ePedsQ

We found that the non-response alert lowered the item non-response rate. The conditional question branch had mixed effects on survey completion time depending on the respondents' age. Surprisingly, respondents rated the vertical question display for handheld devices less legible than the matrix format. Further, multigroup structural equation modelling revealed that the same configuration for both formats showed an acceptable fit.
