[Comparison of the visual analog scale method and 5-point evaluation in student self-assessment of comprehension and...

In examining assessment methods used for evaluating training, there have so far been no studies reporting any differences between the visual analogue scale (VAS) evaluation method, based on a rating scale, and evaluation methods based on an ordinal scale. Here we report the findings of an examination into differences and discrepancies between the results of the VAS method and a 5-point evaluation. Following the end of their training period, seven trainees carried out a self-evaluation regarding their level of understanding and performance using the 5-point evaluation and VAS methods. We then compared the average results of both assessment methods and examined the correlation between the two sets of figures. We found no differences between the 5-point evaluation method and VAS method in evaluating training for dispensing drugs, administering injections, pharmacy preparation, and medication management and instruction. There was also a significant correlation between average values for the 5-point evaluation and VAS method in evaluating training for dispensing drugs, administering injections, pharmacy preparation, and medication management and instruction. This led us to the conclusion that both the 5-point evaluation method and VAS method give similar results and outcomes in assessing the results of practical training.
