The visual analogue scale (VAS) and Likert scale (LS) are widely used but the patients might have difficulties to work with these scales and there might be errors in calculation. Huber, J F HÃ¼sler, J Zumstein, M D Ruflin, G LÃ¼scher, M VASs showed similar properties to Likert-type response scales in most cases. The associations were largely identical, with the exception of an increase in explained variance when predicting age from the VAS version of Excitement Seeking (B10 = 1318.95, Î”R(2) =. Both response scales showed a high overlap and the proposed relationships with age and gender. To assess the validity of the measurements, age and gender were used as criteria, because all three constructs have shown non-zero correlations with age and gender in previous research. Results show comparable reliabilities, means, and SDs for the VAS versions of the original scales, in comparison to Likert-type scales. The questionnaire contained all instruments in both answer scale versions in a counterbalanced design. A sample of 879 participants filled out an online questionnaire measuring Conscientiousness, Excitement Seeking, and Narcissism. The present study expands the comparison of response scales to properties of Internet-based personality scales in a within-subjects design. Visual analogue scales (VASs) have shown superior measurement qualities in comparison to traditional Likert-type response scales in previous studies.
