Cognitive probing was conducted in children to evaluate their understanding of items and the response scale.
Finally, the pre-final version was used and tested to determine understanding of items at the Rehabilitation Department, Phramongkutklao Hospital [ 15].
The MEONF-II demonstrated good user-friendliness in terms of time to complete, ease of understanding of items, as well as ease of completion.
